    Atherogenic indexes versus hematologic inflammatory indexes: What is the most useful predictor of coronary slow flow?
    (Bayrakol Medical Publisher, 2021) Dindas, Ferhat; Koyun, Emin; Cerik, Idris Bugra; Sahin, Anil; Kilit, Celal; Dogdus, Mustafa
    Aim: Previous studies reported that inflammation and atherosclerosis are linked to coronary slow flow (CSF). The predominant pathological mechanism has not been elucidated yet. Hence, we aimed to compare hematologic inflammatory and atherogenic indexes simultaneously between patients with normal coronary flow (NCF) and CSF. Material and Methods: In a single-center retrospective analysis, 91 consecutive NCF patients and 90 consecutive CSF patients constituted two groups according to Thrombolysis in Myocardial Infarction frame count (TFC). Hematological indexes consist of the neutrophil-lymphocyte ratio (NLR), the lymphocyte to monocyte ratio (LMR), and the platelet-lymphocyte ratio (PLR), and the atherogenic indexes consist of an atherogenic index of plasma (AIP), atherogenic coefficient (AC), and Castelli's risk index (CRI). Baseline clinical parameters were compared beside the indexes. Results: NLR, LMR, PLR were similar in groups. AIP, AC and CRI were significantly higher in the CSF group (p<0.05). In correlation analysis, only CRI has significantly positive correlation with mean TFC (r: 0.419 p <0.001). In multivariate regression analysis, CRI was found as independently predictor of CSF (Odds ratio = 2.74, 95% CI = 1.21-6.207; p=0.016). Discussion: An elevated CRI may be an independent predictor for the presence of CSF. Additionally, it can be said that the inflammatory activity in CSF is transformed into atherosclerotic structures.

    Which Coronary Lesions Are More Prone to Cause Acute Myocardial Infarction?
    (ARQUIVOS BRASILEIROS CARDIOLOGIA, 2017) Sen, Taner; Astarcioglu, Mehmet Ali; Beton, Osman; Asarcikli, Lale Dinc; Kilit, Celal
    Background: According to common belief, most myocardial infarctions (MIs) are due to the rupture of nonsevere, vulnerable plaques with < 70% obstruction. Data from recent trials challenge this belief, suggesting that the risk of coronary occlusion is, in fact, much higher after severe stenosis. The aim of this study was to investigate whether or not acute ST-elevation MIs result from high-grade stenoses by evaluating the presence of coronary collateral circulation (CCC). Methods: We retrospectively included 207 consecutive patients who had undergone primary percutaneous coronary intervention for acute ST-elevation MI. Collateral blood flow distal to the culprit lesion was assessed by two investigators using the Rentrop scoring system. Results: Out of the 207 patients included in the study, 153 (73.9%) had coronary collateral vessels (Rentrop 1-3). The Rentrop scores were 0, 1, 2, and 3 in 54 (26.1%), 50 (24.2%), 51 (24.6%), and 52 (25.1%) patients, respectively. Triglycerides, mean platelet volume (MPV), white cell (WBC) count, and neutrophil count were significantly lower in the group with good collateral vessels (p = 0.013, p = 0.002, p = 0.003, and p = 0.021, respectively). Conclusion: More than 70% of the patients with acute MI had CCC with Rentrop scores of 1-3 during primary coronary angiography. This shows that most cases of acute MI in our study originated from underlying high-grade stenoses, challenging the common believe. Higher serum triglycerides levels, greater MPV, and increased WBC and neutrophil counts were independently associated with impaired development of collateral vessels.
