Abnormal Heart Rate Recovery in Stable Heart Failure Patients
Yilmaz, Ahmet; Erdem, Alim; Kucukdurmaz, Zekeriya; Karapinar, Hekim; Gul, Ibrahim; Sarikaya, Savas; Dizman, Rafet (WILEY, 2013)Background Heart rate decrease after exercise, that is associated with reactivation of parasympathetic system, is important, as it is also associated with mortality. Previous studies have shown that this is an independent ... -
Acute Effects of Levosimendan and Dobutamine on QRS Duration in Patients with Heart Failure
Yontar, Osman Can; Yilmaz, Mehmet Birhan; Yalta, Kenan; Erdem, Alim; Tandogan, Izzet (ARQUIVOS BRASILEIROS CARDIOLOGIA, 2010)Background: Levosimendan is a novel inotropic agent that enhances cardiac contractility without increasing cellular calcium intake, so that it is not supposed to cause intracellular calcium overload and related arrhythmias. ... -

Oflaz, Mehmet Burhan; Kucukdurmaz, Zekeriya; Guven, A. Sami; Karapinar, Hekim; Kaya, Ali; Sancakdar, Enver; Deveci, Koksal; Gul, Ibrahim; Erdem, Alim; Cevit, Omer; Icagasioglu, F. Dilara (MARY ANN LIEBERT, INC, 2013)Introduction: Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic viral disease with a high mortality rate. In clinical practice, we observed bradycardia in some pediatric patients with CCHF during the clinical course. ... -
Catheter ablation for atrial fibrillation results in greater improvement in cardiac function in patients with low versus normal left ventricular ejection fraction
Kucukdurmaz, Zekeriya; Kato, Ritsushi; Erdem, Alim; Golcuk, Ebru; Tobiume, Takeshi; Nagase, Takahiko; Ikeda, Yoshifumi; Nakajima, Yoshie; Matsumura, Makoto; Komiyama, Nobuyuki; Nishimura, Shigeyuki; Matsumoto, Kazuo (SPRINGER, 2013)It is still unknown whether left ventricular ejection fraction (LVEF) might affect the magnitude of improvement after atrial fibrillation (AF) ablation on cardiac function in persistent or longstanding persistent AF (CAF) ... -
Comparative effects of levosimendan and dobutamine on right ventricular function in patients with biventricular heart failure
Yilmaz, Mehmet Birhan; Yontar, Can; Erdem, Alim; Karadas, Filiz; Yalta, Kenan; Turgut, Okan Onur; Yilmaz, Ahmet; Tandogan, Izzet (SPRINGER, 2009)Severe heart failure represents a major source of morbidity and mortality. Poor right ventricular function is an independent prognostic marker for mortality in patients with chronic heart failure. In this study, levosimendan ... -
Comparison of myocardial performance index versus ratio of isovolumic contraction time/ejection time in left ventricular systolic dysfunction
Yilmaz, Ahmet; Yalta, Kenan; Turgut, Okan Onur; Yilmaz, Mehmet Birhan; Ozyol, Ali; Erdem, Alim; Tandogan, Izzet (SPRINGER, 2007)Myocardial performance index (MPI) has been regarded as an important parameter in the evaluation of ventricular systolic function in congestive heart failure. This study was designed to investigate the relationship between ... -
Crimean-Congo hemorrhagic fever: does it involve the heart?
Engin, Aynur; Yilmaz, Mehmet Birhan; Elaldi, Nazif; Erdem, Alim; Yalta, Kenan; Tandogan, Izzet; Kaya, Safak; Bakir, Mehmet; Dokmetas, Ilyas (ELSEVIER SCI LTD, 2009)Objective: Crimean-Congo hemorrhagic fever (CCHF) is an acute viral hemorrhagic fever with a high mortality rate. Despite increasing knowledge about viral hemorrhagic fevers, the pathogenesis of CCHF and causes of death ... -
A giant coronary sinus mimicking descending aorta
Yontar, Osman Can; Erdem, Alim; Tandogan, Izzet (ACTA CARDIOLOGICA, 2008)A 58-year-old male patient was admitted to the emergency service with dyspnoea. The patient underwent several laboratory and imaging tests including echocardiography and a diagnosis of descending aortic aneurysm was ... -

Yalta, Kenan; Erdem, Alim; Yilmaz, Ahmet; Turgut, Okan Onur; Yilmaz, Mehmet Birhan; Yontar, Can; Tandogan, Izzet (I C R PUBLISHERS, 2007)Background and aim of the study: Heart rate turbulence (HRT) is a relatively newer parameter which has predictive value for mortality and severity in a variety of cardiovascular diseases. The study aim was to investigate ... -
