Purpose The aim of this study was to investigate the relationship between monocyte count/high density lipoprotein cholesterol (HDL-C) ratio (MHR) and the severity of coronary atherosclerosis, as assessed by the SYNTAX score (SXscore), in patients with stable coronary artery disease (CAD) undergoing coronary angiography. Materials and methods A total of 428 patients were included in the study between...
Background Grade 3 ischemia (G3I) is defined as ST elevation with distortion of the terminal portion of the QRS complex on electrocardiograms (ECGs) of patients with ST-segment elevation myocardial infarction (STEMI). Although the association between G3I and short- and long-term cardiovascular events is well established, its mechanism is unclear. We assessed the association between G3I on the admission...
Objective We aimed to elucidate the relationship between mild-to-moderate renal impairment and the development of coronary collateral vessels (CCV) in patients with acute coronary syndrome (ACS). Methods We enrolled 461 patients with ACS who underwent coronary angiography for the first time. The development of CCV was assessed with the Rentrop score. Kidney function was classified according to the...
Background Fragmented QRS complexes (fQRS) have been associated with increased morbidity and mortality, sudden cardiac death, and recurrent cardiovascular events. The association between left ventricular systolic and diastolic functions and presence of fragmented QRS has not been comprehensively studied to date. We tested the hypothesis that the presence of fragmented QRS is associated with left ventricular...
Background Macrophages in atherosclerotic plaques secrete YKL-40, a new biomarker of acute and chronic inflammation in patients with stable CAD. We hypothesized that YKL-40 may be a specific marker reflecting the burden of localized inflammation in myocardium and a predictor in patients with STEMI. In this study, we investigated the relationship of YKL-40 to in-hospital major adverse cardiac events...
Background Aortic valve sclerosis (AVS) is closely related to hypertension and is an important predictor of coronary artery disease as well as cardiovascular morbidity and mortality. However, the mechanisms causing AVS have not yet been clarified. Therefore, we planned to investigate the influence of atherosclerosis-related risk factors including C-reactive protein (CRP), epicardial adipose tissue...
Background Slow coronary flow (SCF) is an angiographic finding characterized by delayed opacification of the epicardial coronary arteries without obstructive coronary disease. Resistin, an adipocytokine, plays a major role besides low-grade inflammation in atherosclerotic vascular processes and may be of importance in other coronary pathologies such as SCF. Methods The present study was cross-sectional...
