CONTEXT Vitamin D receptors are present in many tissues. Hypovitaminosis D is considered to be a risk factor for atherosclerosis. OBJECTIVE This study explores the effects of vitamin D replacement on insulin sensitivity, endothelial function, inflammation, oxidative stress, and leptin in vitamin D-deficient subjects. DESIGN, SETTING, AND PATIENTS(More)
BACKGROUND Chronic renal failure (CRF) is associated with increased risk of cardiovascular morbidity and mortality. Aspirin resistance worsens clinical prognosis. The aim of this study was to explore the prevalence of aspirin resistance in CRF. METHODS Two hundred and forty-five CRF patients (115 patients undergoing chronic hemodialysis and 130 patients(More)
BACKGROUND Iron-mediated cardiomyopathy is the main cause of death in thalassemia patients. Early detection of cardiac abnormalities is important as aggressive chelation therapy may improve prognosis in these patients. The aim of this study is to evaluate left ventricular (LV) functions by tissue velocity imaging (TVI) and strain imaging (SI) in thalassemia(More)
Narrowing of the arteries due to atherosclerosis may lead to congestive heart failure (CHF). It is advantageous to perform atherosclerosis studies in apolipoprotein E-deficient (Apo E(-/-)) mice models, which develop atherosclerosis very rapidly in comparison to humans. Darbepoetin is a synthetic erythropoietin analogue and stimulates erythropoiesis. The(More)
Cardiac involvement, such as pericarditis, myocarditis, and endocarditis, is seen in juvenile idiopathic arthritis. Although there have been some reports about right-ventricular systolic and diastolic functions of adults with rheumatoid arthritis and left-ventricular systolic and diastolic functions of children with JIA, there have been no studies about RV(More)
Heart-type fatty acid-binding protein (H-FABP), a new biochemical marker of sarcolemmal injury due to acute myocardial ischemia, can be used as a tool in early diagnosis and management of patients at high risk. The aim of this study was to determine the early diagnostic value of H-FABP in acute coronary syndrome (within 6-24 h of chest pain) and to compare(More)
BACKGROUND The evaluation of right ventricular (RV) dysfunction by echocardiography is one of the most important established determinants of the prognosis of acute pulmonary embolism. The aim of the study was to investigate possible association between diameter of right descending pulmonary artery on chest X-rays and RV dysfunction by echocardiography in(More)
BACKGROUND Right ventricular dysfunction and N-terminal proB-type natriuretic peptide (NT-proBNP) are established determinants of prognosis in acute pulmonary embolism (PE). The aim of the study was to investigate the prognostic value of C-reactive protein (CRP) in PE. METHODS Fifty-six patients (mean age, 64.4 T 14.8years; 22 male subjects) with acute PE(More)
BACKGROUND Accelerated atherosclerosis is the major cause of mortality in patients on chronic haemodialysis (HD). Increased oxidative stress might be the major factor leading to high cardiovascular mortality rate in HD patients. The aim of our study was to clarify effects of uraemia and dialysis on oxidative stress parameters and explore the relation(More)
The differences between long-acting dihydropyridines and angiotensin-converting enzyme inhibitors with regard to their long-term effects on 24-h heart rate variability (HRV) and left ventricular (LV) mass are less clear in mild-to-moderate essential hypertension. We studied the long-term effects of amlodipine and fosinopril on 24-h HRV and LV mass in(More)
