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...
Neurocardiogenic syncope comprises situations triggered by neurological reflexes resulting in abnormal responses of the neurocardiovascular system that cause loss of consciousness. A vast number of clinical conditions may cause this disorder including pain, defecation, micturition, swallowing, cough, sudden fear or excitement, exercise, and long-time standing. Treatment options for syncope prevention...
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...
Epidemiological studies have shown that increased serum uric acid (SUA) level is associated with coronary artery disease (CAD). Leukocytes have been shown to play an important role in the atherosclerotic process. The aim of the study was to investigate whether there is any relationship among SUA, leukocyte counts and coronary atherosclerotic burden in patients who are suspected of having CAD.We enrolled...
