BACKGROUND Endothelial dysfunction plays a key role in atherosclerosis and predicts future cardiovascular events in individuals with or without coronary artery disease and improves with risk reduction therapy. We sought to determine the predictive value of endothelial dysfunction for long-term cardiovascular events and in-stent restenosis in patients(More)
OBJECTIVES Postoperative retching and vomiting is an important cause of morbidity that may lead to patient discomfort, distress, and complications. Stimulation of acupuncture points has been shown to be effective in the prevention as well as treatment of PONV. The current treatments of choice are the 5-hydroxytryptamine type 3-antagonists, such as(More)
AIM Metabolic syndrome is associated with increased risk of mortality and morbidity. The present study evaluates the repolarization abnormalities in patients with uncomplicated metabolic syndrome measuring corrected QT interval (QTc) and corrected QT dispersion (QTd) on electrocardiogram. METHODS The study involved 83 subjects. A total of 50 individuals(More)
BACKGROUND Acute decompensated heart failure (HF) is a serious complication associated with significant morbidity and mortality. The CA-125 and NT-proBNP levels have been shown in some studies to predict the outcome, however, the prognostic value of other simple clinical parameters such as pleural effusion has not been established yet. AIM To assess the(More)
Valvular heart diseases cause serious health problems in Turkey as well as in Western countries. According to a study conducted in Turkey, aortic stenosis (AS) is second after mitral valve disease among all valvular heart diseases. AS is frequently observed in elderly patients who have several cardiovascular risk factors and comorbidities. In symptomatic(More)
BACKGROUND & OBJECTIVES In recent years, emerging transcatheter aortic valve implantation (TAVI) has become an alternative for surgery. However, with advanced age, several co-morbid factors together with contrast agent usage can cause deterioration in renal function and increase in the risk of acute kidney injury (AKI) with poor prognosis in patients with(More)
OBJECTIVE Prediabetes is a condition between a normal metabolic state and diabetes mellitus, which includes impaired glucose tolerance (IGT), impaired fasting glucose (IFG), or both. Prediabetes is related with undesirable cardiovascular outcomes. Epicardial fat thickness (EFT) has been correlated with cardiovascular risk factors. We herein aimed to assess(More)
A 67-year-old woman was admitted with aortic valve endocarditis and aortic wall thickening (AWT). Physical examination and laboratory findings yielded infective endocarditis. Echocardiography revealed several small vegetations on the aortic valve, leading to moderate aortic insufficiency together with a small ventricular septal defect. We also became aware(More)
In developing countries, rheumatic valve disease (RVD) is still prevalent. Management of RVD depends on symptomatology, physical examination and echocardiographic evaluation, all of which, however, might be inadequate. Reliable biomarkers to establish severity of RVD and predict complications would be highly beneficial. Urotensin II is regarded as a(More)
The protective effect of severe mitral regurgitation (MR) against left atrial thrombus formation has been well documented. It was also proposed that severe MR may prevent thrombus formation within the left ventricle (LV) with systolic dysfunction. Therefore, we investigated whether ischemic MR prevents thrombus formation within the LV in patients with(More)
