Öğe Burden of comorbidities in heart failure patients in TUrkiye(Tubitak Scientific & Technological Research Council Turkey, 2024) Cavusoglu, Yuksel; Murat, Selda; Sahin, Anil; Colluoglu, Inci Tugce; Ural, Dilek; Yilmaz, Mehmet Birhan; Nalbantgil, SanemBackground/aim: Heart failure (HF) is associated with a wide range of comorbidities that negatively impact clinical outcomes and cause high economic burden. We aimed to evaluate the frequency and burden of comorbidities in HF patients in Turkiye and their relationships with patients' demographic characteristics. Materials and methods: Based on ICD-10 codes in the national electronic database of the Turkish Ministry of Health covering the entire population of Turkiye (n = 85,279,553) from 1 January 2016 to 31 December 2022, data on the prevalence of comorbidities in HF patients were obtained. The frequency and burden of comorbidities were analyzed separately by age groups, sex, and socioeconomic status (SES). Results: Between 2016 and 2022, there were 2,722,151 patients (51.7% female) of all ages who were diagnosed with HF. In Turkiye, the most common comorbidities of HF patients were hypertension (HT) (97.6%), atherosclerotic cardiovascular disease (ASCVD) (84.9%), dyslipidemia (59.5%), anxiety disorder (48.1%), diabetes mellitus (DM) (45.2%), chronic obstructive pulmonary disease (COPD) (43.6%), anemia (40.6%), and atrial fibrillation (AF) (37.1%). Female patients had higher rates of anemia, DM, HT, and anxiety disorders, while male patients had higher rates of ASCVD, COPD, and dyslipidemia. The most common comorbidity in patients under 20 years of age was congenital heart disease (52.3%). More than 90% of HF patients had >= 2 comorbidities. HF patients with >= 5 comorbidities increased from 18.1% in the group aged 20-49 years to 38.3% in the group aged 50-79 years. Comorbidities were similar across SES groups. Conclusion: The most common comorbidities in cases of HF in Turkiye are HT, ASCVD, dyslipidemia, DM, COPD, anemia, and AF, respectively, and more than 90% of patients have >= 2 comorbidities. While ASCVD and dyslipidemia were more common in male patients, anemia, DM, and anxiety disorders were more common in female patients. The number of comorbid conditions increased with advanced age.Öğe Data on prevalence of dyslipidemia and lipid values in Turkey: Systematic review and meta-analysis of epidemiological studies on cardiovascular risk factors(TURKISH SOC CARDIOLOGY, 2018) Kayikcioglu, Meral; Tokgozoglu, Lale; Kilickap, Mustafa; Goksuluk, Huseyin; Karaaslan, Doruk; Ozer, Necla; Abaci, Adnan; Yilmaz, Mehmet Birhan; Barcin, Cem; Ates, Kenan; Bayram, Fahri; Sahin, Mahmut; Ural, DilekObjective: Dyslipidemias, primarily hypercholesterolemia, are independent and strong predictors of cardiovascular (CV) events. The frequency of dyslipidemia is very important in terms of determining CV prevention policies. In order to determine the up-to-date frequency of CV risk factors in Turkey, a meta-analysis of the epidemiologic studies carried out in the last 15 years was performed. This article presents the results on the dyslipidemia data including hypercholesterolemia principally. Methods: Epidemiological studies conducted during the last 15 years and having the potential to represent the general population in Turkey were searched in databases (Ovid Medline, Web of Science Core Collection, and Turkish Academic Network and Information Center [ULAKBIM]) and web pages (Ministry of Health, Turkey Statistical Institute, Turkish Society of Cardiology, Nephrology and Endocrinology Associations). A total of 7 studies including lipid data were found. Systematic review and meta-analysis of the studies with low bias score were performed. Crude values of the prevalence of hypercholeterolemia, hypertriglyceridemia and low HDL and mean lipid levels were calculated. Random effects model was used in meta-analysis. Results: The prevalence of hypercholesterolemia defined as a LDL-cholesterol > 130 and/or >= 130 mg/dL, was 29.1% (95% CI 23.6-35.0) in the general population, 30.2% in females (%95 CI 24.7-36.1), and 27.8% in males (95% CI 22.3-33.6). The prevalence of low HDL-cholesterol (<= 50 mg/dL for females and <= 40 mg/dL for males) was calculated as 46.1% (95% CI 42.4-49.9) in the whole group, 50.7% (95% CI 47.7-53.6) in females and 41.1% (95% CI 36.1-46.3) in males. The prevalence of hypertriglyceridemia (> 150 mg/dL) was 36.5% (95% CI 30.6-42.5) in general, 32.0% (95% GA 26.6-37.8) in females and 41.3% (95% CI 34.9-47.8) in males. Conclusion: Dyslipidemia constitutes a major public health problem in Turkey. In the adult population, almost 3 of 10 have hypercholesterolemia, one of 2 has a low HDL-cholesterol, and 1 of 3 has high triglycerides levels.Öğe Data on prevalence of hypertension and blood pressure in Turkey: Systematic review, meta-analysis and meta-regression of epidemiological studies on cardiovascular risk factors(TURKISH SOC CARDIOLOGY, 2018) Kilickap, Mustafa; Barcin, Cem; Goksuluk, Huseyin; Karaaslan, Doruk; Ozer, Necla; Kayikcioglu, Meral; Ural, Dilek; Yilmaz, Mehmet Birhan; Abaci, Adnan; Arici, Mustafa; Altun, Bulent; Tokgozoglu, Lale; Sahin, MahmutObjective: Cardiovascular risc factors may show significant changes over the years. A systematic review and meta-analysis of epidemiological studies conducted in Turkey was performed to assess the latest profile and temporal changes in cardiovascular risk factors. Presented here are the data on hypertension (HT) and blood pressure (BP). Methods: Ovid Medline, the Web of Science Core Collection, and the Turkish Academic Network and Information Center (ULAKBIM) were searched for epidemiological studies conducted in Turkey during the last 15 years. In addition, the web pages of the Ministry of Health, the Turkish Statistical Institute, and associations of cardiology, nephrology, and endocrinology were searched for appropriate studies. Regional studies were excluded. The studies included were assessed with a bias score developed by our team, then categorized as having a low risk or a high risk of bias. The crude values of HT prevalence and BP were pooled using a random effects model. Meta-regression was performed to explain heterogeneity and to assess temporal changes. Results: The agreement between the 2 authors on the selection and bias scoring of the studies was perfect (Kappa >= 0.95). There were 7 (n=73218) studies providing HT prevalence data, and 8 (n=75879) studies with BP data. The heterogeneity between the studies was high. Meta-analysis of the studies with a low risk of bias indicated that the crude prevalence of HT is higher in women, but that BP levels were similar in both sexes. The HT prevalence and BP value decreased between 2003 and 2012; however, the number of hypertensives stabilized at approximately 15 million, and the number of uncontrolled hypertensives, despite some decrease, was around 11 million. Conclusion: Despite some improvement, HT is still an important public health problem in Turkey.Öğe Data on prevalence of obesity and waist circumference in Turkey: Systematic review, meta-analysis and meta-regression of epidemiological studies on cardiovascular risk factors(TURKISH SOC CARDIOLOGY, 2018) Ural, Dilek; Kilickap, Mustafa; Goksuluk, Huseyin; Karaaslan, Doruk; Kayikcioglu, Meral; Ozer, Necla; Barcin, Cem; Yilmaz, Mehmet Birhan; Abaci, Adnan; Sengul, Sule; Arinsoy, Turgay; Erdem, Yunus; Sanisoglu, Yavuz; Sahin, Mahmut; Tokgozoglu, LaleObjective: Obesity is the most important epidemic of the 21st century and its incidence is increasing steadily in Turkey. The aim of this study was to assess the current status and temporal change in the prevalence of obesity in Turkey with a systematic review and meta-analysis of epidemiological studies conducted in the last 15 years. Methods: Ovid Medline, the Web of Science Core Collection and the Turkish Academic Network and Information Center (ULAKBIM) databases, as well as the web pages of the Turkish Ministry of Health, the Turkish Statistical Institute, and cardiology, nephrology and endocrinology associations were searched for epidemiological studies conducted within Turkey the last 15 years. Research focusing on local data was excluded. Studies included in the analysis were assessed with a special bias score and categorized as having low or high risk of bias. Body mass index (BMI), waist circumference, obesity and prevalence of abdominal obesity were calculated as crude values. Meta-regression analysis was performed to assess heterogeneity and change over time. Results: The agreement between the two investigators on the selection and bias scoring of the studies was excellent (kappa=0.95), but the heterogeneity between the studies was high. BMI (10 studies, n=93.554) was calculated as 28.2 kg/m(2) for women and 26.5 kg/m(2) for men. The prevalence of obesity (12 trials, n=106.553) was 33.2% in females and 18.2% in males. In 6 studies (n=66.591) that included a measurement of waist circumference, the values were 89.72 cm in women and 93.57 cm in men. Especially in women, the prevalence of abdominal obesity (5 studies, n=62331) was greater than that of general obesity (50.8% in women vs 20.8% in men). Meta-regression analysis revealed that the variance of the obesity prevalence between the studies could partly be explained by the age differences, but there was no temporal change in the prevalence of obesity during the years the studies were conducted. Conclusion: The prevalence of obesity, especially abdominal obesity, is considerably high in Turkish women and increases with advancing age. This finding points out that nationwide action plans against obesity, especially for women, should be designed and implemented by health policy makers.Öğe Deciphering mortality risk of diabetes medications in heart failure patients with diabetes mellitus under triple guideline-directed medical therapy(Elsevier Ireland Ltd, 2024) Colluoglu, Inci Tugce; Celik, Ahmet; Ata, Naim; Ural, Dilek; Sahin, Anil; Ulgu, Mustafa Mahir; Kanik, Emine ArzuBackground: Scientific evidence regarding the impact of different combinations of diabetes medications in heart failure patients with diabetes mellitus (HFwDM) remains limited. Aim: We aimed to investigate the effect of monotherapy and combination therapy for DM on all -cause mortality in HFwDM under triple guideline -directed medical therapy (GDMT). Method: This nationwide retrospective cohort study included adult HFwDM under triple GDMT between January 1, 2016 and December 31, 2022.We collected the data from the National Electronic Database of the Turkish Ministry of Health.We created various combination including different diabetes medications based on the current guidelines for DM.The primary endpoint was all -cause mortality. Results: A total of 321,525 HFwDM under triple GDMT (female:49%, median age:68[61 -75] years) were included. The highest rate of prescribed combination therapy was metformin and sulfonylureas ( n = 55,266). In Cox regression analysis, ins & uuml;lin monotherapy had the highest risk for all -cause mortality (HR:2.25, 95CI%:2.062.45), whereas combination therapy including metformin, SGLT2i, and sulfonylureas provided the most beneficial effect on survival (HR:0.29, 95CI%:0.22 -0.39) when compared to patients not receiving diabetes medication. Among patients taking diabetes medications, the inclusion of SGLT2i demonstrated a survival benefit ( p < 0.05), despite concurrent use of volume -retaining medications such as insulin and thiazolidinediones. Conversely, combinations of diabetes medications without SGLT2i did not demonstrate any survival benefit compared to patients not taking diabetes medication ( p > 0.05). Conclusion: This study underscored the use of SGLT2i as monotherapy or as a part of combination diabetes medications to improve survival among HFwDM, while also highlighting that combinations lacking SGLT2i did not confer any survival benefit.Öğe Diagnosis and management of acute heart failure(TURKISH SOC CARDIOLOGY, 2015) Ural, Dilek; Cavusoglu, Yuksel; Eren, Mehmet; Karauzum, Kurtulus; Temizhan, Ahmet; Yilmaz, Mehmet Birhan; Zoghi, Mehdi; Ramassubu, Kumudha; Bozkurt, BiykemAcute heart failure (AHF) is a life threatening clinical syndrome with a progressively increasing incidence in general population. Turkey is a country with a high cardiovascular mortality and recent national statistics show that the population structure has turned to an 'aged' population. As a consequence, AHF has become one of the main reasons of admission to cardiology clinics. This consensus report summarizes clinical and prognostic classification of AHF, its worldwide and national epidemiology, diagnostic work-up, principles of approach in emergency department, intensive care unit and ward, treatment in different clinical scenarios and approach in special conditions and how to plan hospital discharge.Öğe Diagnosis and management of acute heart failure(Turkish Society of Cardiology, 2015) Ural, Dilek; Çavuşoğlu, Yüksel; Eren, Mehmet; Karaüzüm, Kurtuluş; Temizhan, Ahmet; Yılmaz, Mehmet Birhan; Zoghi, MehdiAcute heart failure (AHF) is a life threatening clinical syndrome with a progressively increasing incidence in general population.

The aim of this study was to review the diagnostic approach to HF in Turkiye. Materials and methods: This study is a subanalysis of the nationwide TRends-HF study, based on anonymized data from National Electronic Database between January 1, 2016, and December 31, 2022. Variables including date of birth, sex, socioeconomic development index, place of initial HF diagnosis, comorbidities, investigations, and diagnostic procedures were reported. Laboratory variables, including complete blood count, natriuretic peptides (NP), estimated glomerular filtration rate, uric acid, electrolytes, albumin, lipid profile, ferritin and hemoglobin A1c levels, and other imaging techniques (coronary angiogram [CAG], transthoracic echocardiography [TTE], chest X-ray [CXR], etc.) during the initial diagnosis and/or follow-up of HF patients, were obtained from the National Electronic Database. The diagnostic test usage rates were analyzed according to years, geographical regions, and socioeconomic regions of Turkiye. Results: The study population consisted of 2,722,151 HF patients (51.7% female, mean age 68.33 +/- 14.01 years). All HF patients had at least one electrocardiogram and one TTE examination, and all underwent routine biochemical tests at least once during the followup period. CXR utilization rate was 93.7%, while CAG utilization rate was 17.9%. Coronary computed tomographic angiography and cardiac magnetic resonance imaging were performed in only 1.8% and 0.3% of patients, respectively. Among all Turkish HF patients, 16.3% had at least one NP measurement. The highest rate of NP use was observed in the Central Anatolia Region (21.0%), while the lowest rate was in the Aegean Region (11.7%). NP measurement during HF diagnosis revealed a rising trend over time (12.3% in 2016 vs. 26.3% in 2021). Conclusion: The widespread use of TTE at the beginning of the diagnosis and during follow-up is important for providing quality care to HF patients in Turkiye. However, detailed laboratory tests and advanced imaging methods are not utilized sufficiently, which could lead to issues in patient management.Öğe Exploring Regional Disparities in Heart Failure Epidemiology and Outcomes: A Comprehensive Study Across Geographical Regions in Türkiye(Galenos Publ House, 2024) Sahin, Anil; Coellueoglu, Tugce; Celik, Ahmet; Ata, Naim; Yilmaz, Mehmet Birhan; Ural, Dilek; Kanik, ArzuBackground: Heart failure (HF) is a common condition that affects 1-3% of the general population. Its prevalence exhibits notable international and intranational disparities, partly explained by socioeconomic status, religion, ethnic diversity, and geographic factors. A comprehensive understanding of the epidemiological symptoms of HF in different regions of Turkiye has yet to be revealed. Aims: To examine epidemiological data from 2016 to 2022, focusing on crucial patient characteristics and geographical regions, to determine the incidence and prevalence of HF in Turkiye across seven diverse geographical regions.Study Design: A nationwide population-based retrospective cohort study.Methods: The comprehensive National Electronic Database of the Turkish Ministry of Health was used in this study to obtain data that covers the whole Turkish population from January 1, 2016, to December 31, 2022. The International Classification of Diseases-10 (ICD-10) codes were used to identify adults with HF (n = 2,701,099) and associated comorbidities. Turkiye is divided into seven geographically distinct regions. Epidemiological characteristics and survival data of these regions were analyzed separately. All-cause mortality was set as the primary outcome. Results: In , the total estimated prevalence of adult patients with HF is 2.939%, ranging from 2.442% in Southeastern Anatolia to 4.382% in the Black Sea Region. Except for the Eastern Anatolia Region, the three most often reported comorbidities were hypertension, dyslipidemia, and anxiety disorders. The rates of prescribing guideline-directed medical therapy (GDMT) for HF and other medications varied significantly. GDMT prescription rates were lowest in the Eastern Anatolia Region (82.6% for beta-blockers, 48.7% for RASi, 31.8% for mineralocorticoid receptor antagonists, and 9.4% for SGLT2i). The Mediterranean and Aegean regions had the highest median N-terminal brain natriuretic peptide (NT-proBNP) levels of 1,990,0 pg/ml (518.0-6,636,0) and 1,441,0 pg/ml (363.0-5,000,0), respectively. From 2016 to 2022, 915,897 (33.9%) of 2,701,099 patients died. The Eastern Anatolia Region had the lowest all-cause mortality rate of 26.5%, whereas the Black Sea Region had the highest all-cause mortality rate of 35.3%.Conclusion: Our real-world analysis revealed geographic disparities in HF characteristics, such as decreased mortality in socioeconomically challenged regions. Higher stress susceptibility in developed regions may increase the likelihood of adverse outcomes.Öğe Heart and brain interaction in patients with heart failure: overview and proposal for a taxonomy. A position paper from the Study Group on Heart and Brain Interaction of the Heart Failure Association(WILEY, 2018) Doehner, Wolfram; Ural, Dilek; Haeusler, Karl Georg; Celutkiene, Jelena; Bestetti, Reinaldo; Cavusoglu, Yuksel; Pena-Duque, Marco A.; Glavas, Duska; Iacoviello, Massimo; Laufs, Ulrich; Marmol Alvear, Ricardo; Mbakwem, Amam; Piepoli, Massimo F.; Rosen, Stuart D.; Tsivgoulis, Georgios; Vitale, Cristiana; Yilmaz, M. Birhan; Anker, Stefan D.; Filippatos, Gerasimos; Seferovic, Petar; Coats, Andrew J. S.; Ruschitzka, FrankHeart failure (HF) is a complex clinical syndrome with multiple interactions between the failing myocardium and cerebral (dys-)functions. Bi-directional feedback interactions between the heart and the brain are inherent in the pathophysiology of HF: (i) the impaired cardiac function affects cerebral structure and functional capacity, and (ii) neuronal signals impact on the cardiovascular continuum. These interactions contribute to the symptomatic presentation of HF patients and affect many co-morbidities of HF. Moreover, neuro-cardiac feedback signals significantly promote aggravation and further progression of HF and are causal in the poor prognosis of HE The diversity and complexity of heart and brain interactions make it difficult to develop a comprehensive overview. In this paper a systematic approach is proposed to develop a comprehensive atlas of related conditions, signals and disease mechanisms of the interactions between the heart and the brain in HF. The proposed taxonomy is based on pathophysiological principles. Impaired perfusion of the brain may represent one major category, with acute (cardio-embolic) or chronic (haemodynamic failure) low perfusion being sub-categories with mostly different consequences (i.e. ischaemic stroke or cognitive impairment, respectively). Further categories include impairment of higher cortical function (mood, cognition), of brain stem function (sympathetic over-activation, neuro-cardiac reflexes). Treatment-related interactions could be categorized as medical, interventional and device-related interactions. Also interactions due to specific diseases are categorized. A methodical approach to categorize the interdependency of heart and brain may help to integrate individual research areas into an overall picture.Öğe Impact of implantable cardioverter defibrillators on mortality in heart failure receiving quadruple guideline-directed medical therapy: a propensity score-matched study(Bmc, 2024) Sahin, Anil; Celik, Ahmet; Ural, Dilek; Colluoglu, Inci Tugce; Ata, Naim; Kanik, Emine Arzu; Ulgu, Mustafa MahirBackgroundIn the contemporary management of heart failure with reduced ejection fraction (HFrEF), the recommended quadruple guideline-directed medical therapy (GDMT) consists of angiotensin receptor-neprilysin inhibitor (ARNI), evidence-based beta-blockers (BB), mineralocorticoid receptor antagonists (MRA), and sodium-glucose cotransporter-2 inhibitors (SGLT-2i). This study explored the impact of adding implantable cardioverter-defibrillator (ICD) therapy to this comprehensive regimen in HFrEF patients.MethodsUtilizing deidentified data from the National Electronic Database of the Turkish Ministry of Health, we conducted a nationwide retrospective cohort study on 5450 HFrEF patients receiving quadruple GDMT, including ARNI. Among them, 709 patients underwent additional ICD or cardiac resynchronization therapy defibrillator (CRT-D) implantation. Propensity score matching ensured balanced baseline characteristics between groups. Primary endpoint was determined as all-cause mortality.ResultsIn the matched cohort, all-cause mortality occurred in 108 out of 619 patients (17.4%) in the GDMT group and 101 out of 619 patients (16.3%) in the ICD group, with a hazard ratio (HR) of 0.74 and a 95% confidence interval (CI) ranging from 0.57 to 0.98. The median follow-up time was 1365 days in the matched cohort, 1283 days in the GDMT group. Subgroup analyses consistently demonstrated benefits, particularly among individuals aged 61 years and older (HR: 0.60, 95% CI: 0.42-0.87, p = 0.006), those with sinus rhythm (HR: 0.55, 95% CI: 0.34-0.89, p = 0.013), individuals not using amiodarone (HR: 0.61, 95% CI: 0.42-0.89, p = 0.011), and those with an estimated glomerular filtration rate lower than 61.9 (HR: 0.66, 95% CI: 0.48-0.91, p = 0.011).ConclusionsThis study may offer a glimmer of hope that even after achieving the best current optimal medical therapy, the addition of device therapy could still yield positive outcomes in the management of patients with HFrEF.Öğe In Response to The Importance of Age Standardisation in Comparing Regional Inequalities(Galenos Publ House, 2025) Sahin, Anil; Colluoglu, Tugce; Celik, Ahmet; Ata, Naim; Yilmaz, Mehmet Birhan; Ural, Dilek; Kanik, Arzu[No abstract available]Öğe Iron deficiency and anemia in heart failure(TURKISH SOC CARDIOLOGY, 2017) Cavusoglu, Yuksel; Altay, Hakan; Cetiner, Mustafa; Guvenc, Tolga Sinan; Temizhan, Ahmet; Ural, Dilek; Yesilbursa, Dilek; Yildirim, Nesligul; Yilmaz, Mehmet BirhanHeart failure is an important community health problem. Prevalence and incidence of heart failure have continued to rise over the years. Despite recent advances in heart failure therapy, prognosis is still poor, rehospitalization rate is very high, and quality of life is worse. Co-morbidities in heart failure have negative impact on clinical course of the disease, further impair prognosis, and add difficulties to treatment of clinical picture. Therefore, successful management of co-morbidities is strongly recommended in addition to conventional therapy for heart failure. One of the most common co-morbidities in heart failure is presence of iron deficiency and anemia. Current evidence suggests that iron deficiency and anemia are more prevalent in patients with heart failure and reduced ejection fraction, as well as those with heart failure and preserved ejection fraction. Moreover, iron deficiency and anemia are referred to as independent predictors for poor prognosis in heart failure. There is strong relationship between iron deficiency or anemia and severity of clinical status of heart failure. Over the last two decades, many clinical investigations have been conducted on clinical effectiveness of treatment of iron deficiency or anemia with oral iron, intravenous iron, and erythropoietin therapies. Studies with oral iron and erythropoietin therapies did not provide any clinical benefit and, in fact, these therapies have been shown to be associated with increase in adverse clinical outcomes. However, clinical trials in patients with iron deficiency in the presence or absence of anemia have demonstrated considerable clinical benefits of intravenous iron therapy, and based on these positive outcomes, iron deficiency has become target of therapy in management of heart failure. The present report assesses current approaches to iron deficiency and anemia in heart failure in light of recent evidence.Öğe Lymphocytopenia is associated with poor NYHA functional class in chronic heart failure patients with reduced ejection fraction(TURKISH SOC CARDIOLOGY, 2015) Yucel, Hasan; Ege, Meltem Refiker; Zorlu, Ali; Kaya, Hakki; Beton, Osman; Gungor, Hasan; Acar, Gurkan; Temizhan, Ahmet; Cavusoglu, Yuksel; Zoghi, Mehdi; Eren, Mehmet; Ural, Dilek; Yilmaz, Mehmet BirhanObjective: In heart failure (HF) patients, functional capacity has been demonstrated to be a marker of poor prognosis, independent of left ventricular ejection fraction (EF). Lymphocyte count is currently recognized in certain risk stratification scores for chronic HF, and severe HF is associated with lymphocytopenia. However, no data exists on the association between lymphocyte count and functional capacity in patients with stable HF. This study aimed to assess the relationship between lymphocyte count and New York Heart Association (NYHA) functional capacity in systolic HF outpatients. Methods: The Turkish Research Team-HF (TREAT-HF) is a network which undertakes multi-center observational studies in HF. Data on 392 HF reduced ejection fraction (HFREF) patients from 8 HF centers are presented here. The patients were divided into two groups and compared: Group 1 comprised stable HFREF patients with mild symptoms NYHA Class (I-II), while Group 2 consisted of patients with NYHA Class III-IV symptoms. Results: Patient mean age was 60 +/- 14 years. Lymphocyte count was lower in patients with NYHA functional classes III and IV than in patients with NYHA functional classes I and II, 0.9 [0.6-1.5] x1000 versus 1.5 [0.7-2.2] x1000, p<0.001). In multivariate logistic regression analysis, lymphocyte count OR: 0.602, 95% CI: 0.375-0.967, p=0.036), advanced age, male gender, presence of hypertension, EF, left atrium size, systolic pulmonary artery pressure, neutrophil and basophil counts, creatinine level, and diuretic usage were associated with poor NYHA functional class in systolic HF outpatients. Conclusion: The present study demonstrated that in stable HFREF outpatients, lymphocytopenia was strongly associated with poor NYHA function, independent of coronary heart disease risk factors.Öğe Navigating Heart Failure: Unveiling Sex Disparities in Guideline-Directed Medical Therapy Combinations(Excerpta Medica Inc-Elsevier Science Inc, 2024) Celik, Ahmet; Sahin, Anil; Ata, Naim; Colluoglu, Inci Tugce; Ural, Dilek; Kanik, Emine Arzu; Ayvali, Mustafa OkanMajor heart failure (HF) trials remain insufficient in terms of assessing the differences in clinical characteristics, biomarkers, treatment efficacy, and safety because of the underrepresentation of women. The study aimed to present sex-related disparities in HF management, including differences in demographics, co-morbidities, cardiac biomarkers, prescribed medications, and treatment outcomes. The study utilized anonymized data from and December 31, 2022. The cohort analysis included 2,501,231 adult patients with HF. Specific therapeutic combinations were analyzed using a Cox regression model to obtain relative risk reduction for all-cause death. The primary end point was all-cause mortality. In the cohort, 48.7% (n = 1,218,911) were male, whereas 51.3% (n = 1,282,320) were female. Female patients exhibited a higher median age (71 vs 68 years) and manifested higher prevalence of diabetes mellitus, anemia, atrial fibrillation, anxiety, and ischemic stroke. Male patients demonstrated higher rates of previous myocardial infarction, dyslipidemia, chronic obstructive pulmonary disease, and chronic kidney disease. Higher concentrations of natriuretic peptides were observed in female patients. Renin-angiotensin aldosterone inhibitor, b blockers, mineralocorticoid receptor antagonists, sodium/glucose cotransporter 2 inhibitor (SGLT2i), and ivabradine were more commonly prescribed in male patients, whereas loop diuretics, digoxin, and ferric carboxymaltose were more frequent in female patients. Male patients had higher rates of cardiac resynchronization therapy and implantable cardioverter defibrillator implantation rates. All-cause mortality and hospitalization rates were higher in male patients. Compared with monotherapy, all combinations, including SGLT2i, showed a beneficial effect on all-cause mortality in both female and male patients with HF. In hospitalized patients with HF, the addition of digoxin to renin-angiotensin aldosterone inhibitor, mineralocorticoid receptor antagonists, and b blockers was superior to monotherapy regarding all-cause mortality in female patients with HF compared with male patients with HF. In conclusion, this study highlights that sex-specific responses to HF medication combinations compared with monotherapy and differences in co-morbidities underscore the importance of tailored management strategies. Digoxin showed a contrasting effect on allcause mortality between both sexes after hospitalization, whereas SGLT2i exhibited a consistent beneficial effect in both sexes when added to all combinations.

(Am J Cardiol 2024;216:27-34)Öğe Outcomes of patients with heart failure in Turkiye(Tubitak Scientific & Technological Research Council Turkey, 2024) Sahin, Anil; Yilmaz, Mehmet Birhan; Celik, Ahmet; Colluoglu, Inci Tugce; Ural, Dilek; Asarcikli, Lale Dinc; Nalbantgil, SanemBackground/aim: Despite T & uuml;rkiye's relatively young population, there is an emerging trend of earlier diagnoses of chronic diseases, including heart failure (HF). This study aims to shed light on survival rates, potential influences of guideline-directed therapies, and sex-based differences necessitating personalized management in HF. Materials and methods: We conducted a nationwide retrospective cohort analysis of 2,722,151 patients with HF using deidentified data from the Turkish Ministry of Health's national electronic database. That cohort included 2,701,099 adult patients with HF. Adult patients were divided into two groups based on their outcomes as those who were deceased and those who survived and were then compared. Multivariate regression analysis was conducted to identify variables predicting mortality. The patients' hospital admissions and length of hospital stay were analyzed based on survival status and age. Results: Out of 2,722,151 HF patients, the overall mortality rate was 33.7%, with a difference observed according to sex (32.5% in female patients, 35.0% in male patients). Survival rates at 1, 5, and 7 years after the HF diagnosis were detailed. Deceased HF patients had more comorbidities, higher natriuretic peptides, and lower glomerular filtration rates. Hospitalization patterns varied, with 41% experiencing no hospitalization. The average length of hospital stay in 2022 was 6 days, with sex- and age-specific disparities. Conclusion: The survival rate of HF in T & uuml;rkiye is similar to world data. The survival of female patients is better than that of male patients. Increased survival rates can likely be attributed to the widespread use of guideline-directed therapies. Finally, high healthcare utilization is observed, especially in emergency situations.Öğe Real-Life Individual Comparison of Sodium-Glucose Cotransporter-2 Inhibitors in Patients with Heart Failure and Diabetes Mellitus(Adis Int Ltd, 2025) Yilmaz, Mehmet Birhan; Celik, Ahmet; Colluoglu, Tugce; Sahin, Anil; Ural, Dilek; Kanik, Arzu; Ata, NaimBackgroundSodium-glucose cotransporter-2 inhibitors (SGLT2is) are breakthrough agents for the treatment of type 2 diabetes mellitus (T2DM) and heart failure (HF). However, among patients with HF and T2DM, some uncertainty remains about individual comparisons, including dosing.ObjectivesWe aimed to make a real-life individual comparison of SGLT2is among patients with HF and T2DM.MethodsThis was a subgroup analysis of the Turkish Ministry of Health's National Electronic Database for adult patients with HF (TRends-HF). All-cause mortality (ACM) data up to 7 years were evaluated. Patients with HF and T2DM who were prescribed an SGLT2i were identified, and individual doses of empagliflozin 25 mg, empagliflozin 10 mg, and dapagliflozin 10 mg were compared. For individual comparisons, propensity score-matching analysis was generated as 1:1:1, and disease-modifying therapies (DMTs) for HF were considered.ResultsIn the triple-matched cohort, 1-, 5-, and 7-year survival rates were 95%, 81%, and 76% versus 94%, 78%, and 72% versus 94%, 80%, and 75% for empagliflozin 25 mg, empagliflozin 10 mg, and dapagliflozin 10 mg, respectively. Among patients who were on triple DMT for HF, 1-, 5-, and 7-year survival rates were 95%, 78%, and 70% for empagliflozin 25 mg, 95%, 74%, and 66% for empagliflozin 10 mg, and 94%, 77%, and 69% for dapagliflozin, respectively. Annual emergency department visits were slightly lower with empagliflozin 10 mg and dapagliflozin 10 mg than with empagliflozin 25 mg. A greater proportion of patients on dapagliflozin 10 mg did not experience hospitalization during the 7-year follow-up compared with both doses of empagliflozin, albeit with a small effect size.ConclusionAmong patients with HF and T2DM, SGLT2is are instrumental, and empagliflozin 10 mg remains significantly inferior to dapagliflozin 10 mg and empagliflozin 25 mg in terms of 5- and 7-year ACM.Öğe Timing and Adherence Matter for Sodium-Glucose Cotransporter-2 Inhibitors in Heart Failure(Wiley, 2025) Yilmaz, Mehmet Birhan; Celik, Ahmet; Sahin, Anil; Colluoglu, Tugce; Ural, Dilek; Kanik, Arzu; Ata, NaimBackground It is imperative to maintain the use of sodium-glucose cotransporter-2 inhibitors (SGLT-2is) in patients with diabetes both after the index diagnosis of heart failure (HF) and even prior to the index diagnosis of HF. We aimed to investigate whether timing of SGLT-2 is before the index diagnosis of HF, and second, adherence to SGLT-2is in the form of the proportion of days covered metric matter in patients with HF and diabetes. Methods and Results All-cause death up to 7 years were evaluated in HF with diabetes from the subgroup analysis of TRends-HF (TRends in Heart Failure in T & uuml;rkiye). Patients with HF and diabetes, who were prescribed an SGLT-2i either before or after the index diagnosis of HF were identified, categorized according to duration of exposure before the index HF diagnosis and according to proportion of days covered after the index diagnosis of HF, and compared with nonusers. There were 1 229 833 patients with HF and diabetes in the cohort. A total of 247 987 were on an SGLT-2i and had available timing data, and 14.06% had SGLT-2i on board before the index HF diagnosis. Median duration of SGLT-2i exposure before the index HF diagnosis was 417 days. Prognosis was the best among patients with diabetes who were prescribed an SGLT-2i before the index diagnosis of HF with an exposure more than median duration. Of note, among patients who were prescribed an SGLT-2i after the index HF diagnosis; there was a numerically graded increase in all-cause mortality rate such that a >10% decrease in SGLT-2i proportion of days covered was associated with a 59% increase in all-cause death (hazard ratio, 1.21-2.09). Conclusions Regardless of time or adherence, SGLT-2is offer a remarkable all-cause death benefit to patients with HF and diabetes. SGLT-2is' all-cause death benefit for patients with HF and diabetes was greatest when it was prescribed before the HF index diagnosis. Poor adherence to SGLT-2is was associated with worsening survival in patients with HF and diabetes following the diagnosis of index HF.Öğe Trends in heart failure between 2016 and 2022 in Türkiye (TRends-HF): a nationwide retrospective cohort study of 85 million individuals across entire population of all ages(Elsevier, 2023) Celik, Ahmet; Ural, Dilek; Sahin, Anil; Colluoglu, Inci Tugce; Kanik, Emine Arzu; Ata, Naim; Arugaslan, EmreBackground Data on the burden of heart failure (HF) outside western countries are limited, but available data suggest it may present differently in other countries. The aim of this study was to examine the incidence, prevalence, and survival rates of HF in Turkiye, with a specific focus on how these rates vary according to age, sex, comorbidities, and socioeconomic status (SES).Methods We harnessed the extensive National Electronic Database of the Turkish Ministry of Health, covering Turkey's entire population from January 1, 2016, to December 31, 2022, to identify 2,722,151 cases of HF and their associated comorbidities using ICD-10 codes. Analyzing the primary endpoint of all-cause mortality, our study utilized anonymized data to examine patient demographics, comorbidities, socioeconomic status, and survival patterns, employing statistical techniques to delve into relationships and trends. The data were segmented by gender, socioeconomic status, and age, involving cross-tabulations and statistical metrics to explore connections, odds ratios, and survival rates.Findings The estimated prevalence of HF was 2.114% in Turkiye at the end of 2022, with an annual incidence ranging between 3.00 and 6.06 per 1000 person years. Females were older than males (69.8 +/- 13.9 years vs. 66.8 +/- 13.9 years, respectively). The most common comorbidities were congenital heart diseases and anemia under the age of 20, and hypertension and atherosclerotic cardiovascular disease in the adult population. Only 23.6% (643,159/2,722,151) of patients were treated with any triple guideline-directed medical therapy (GDMT) and 3.6% (96,751/2,722,151) of patients were on quadruple GDMT. The survival rates for patients with HF at 1, 5, and 7 years were 83.3% (95% CI: 83.2-83.3), 61.5% (95% CI: 61.4-61.6), and 57.7% (95% CI: 57.6-57.8) among females, and 82.1% (95% CI: 82.0-82.2), 58.2% (95% CI: 58.1-58.3), and 54.2% (95% CI: 54.0-54.3) among males. Despite a tendency for an increase from the highest to the lowest SES, the prevalence of HF and mortality were paradoxically lowest in the lowest SES region.Interpretation The prevalence, incidence, and survival rates of HF in Turkiye were comparable to western countries, despite the notable difference of HF onset occurring 8-10 years earlier in the Turkish population. Drug usage statistics indicate there is a need for effective strategies to improve treatment with GDMT.Öğe Why has the incidence of heart failure decreased by half in Türkiye?-Authors' reply(Elsevier, 2023) Celik, Ahmet; Colluoglu, Inci Tugce; Sahin, Anil; Ural, Dilek; Yilmaz, Mehmet Birhan; Ataf, Naim[Abstract Not Available]
