BACKGROUND Fragmented QRS complex (fQRS) is associated with increased morbidity and mortality, sudden cardiac death and recurrent cardiovascular events. However, its prognostic role has not been studied comprehensively in patients undergoing coronary artery bypass graft (CABG) surgery. In this study, we investigated the relationship between the presence of(More)
BACKGROUND Ascending aortic aneurysm is an uncommon condition with lethal consequences. Lately, epicardial adipose tissue (EAT) is acknowledged as an organ with important effects on the vascular system. In this study, we aimed to investigate whether EAT, cardiovascular risk factors, and vascular structure and functions are independently related to ascending(More)
BACKGROUND Hypertension, identifiable by elevated blood pressure (BP), is a heterogeneous multifactorial disorder. Epicardial adipose tissue (EAT), a special fat depot that is related to visceral fat rather than total adiposity, shares the same microcirculation with myocardial tissue and coronary vessels. Recent studies have identified EAT as an active(More)
BACKGROUND QRS complex fragmentations can frequently be seen on routine ECG with narrow or wide QRS complex. Fragmented QRS complexes (fQRS) are defined as various RSR' patterns (≥ 1 R' or notching of S wave or R wave) in two contiguous leads corresponding to a major coronary artery territory. In previous studies, fQRS has been associated with increased(More)
BACKGROUND AND OBJECTIVES Fragmented QRS complexes (fQRS) are associated with increased morbidity and mortality. The causative relationship between fQRS and cardiac fibrosis has been shown, but whether the presence and the number of fQRS on admission of electrocardiogram (ECG) predicts ST segment resolution in patients undergoing primary percutaneous(More)
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. The(More)
BACKGROUND AND OBJECTIVES QRS complex fragmentations are frequently seen on routine electrocardiograms with narrow or wide QRS complex. Fragmented QRS complex (fQRS) is associated with increased morbidity and mortality, sudden cardiac death and recurrent cardiovascular events. In this study, we aimed to interrogate the relationship of systemic inflammation(More)
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(More)
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(More)
OBJECTIVE Bilirubin is a bile pigment with potent anti-oxidant properties; in previous studies it has been reported to be negatively associated with coronary artery disease (CAD). Although elevated serum bilirubin concentrations may protect against endothelial dysfunction, it is not clear whether higher serum bilirubin levels (SBLs) in physiological ranges(More)
