BACKGROUND Implantable cardioverter defibrillators (ICDs) are life-saving devices in treatment of life-threatening arrhythmia. We evaluate the emotional status of Turkish patients with ICD and try to explain factors that affect emotional status of the patients. METHODS Ninety-one patients with previously implanted ICD were included in the study. Follow-up(More)
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 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)
Chronic thromboembolic pulmonary hypertension (CTEPH) is a progressive disease characterized by increased pulmonary vascular resistance resulting in pulmonary hypertension and right heart failure. The six-minute walk test (6MWT) distance is associated with the prognosis of CTEPH patients. Speckle tracking echocardiography (STE) is a reliable method for(More)
OBJECTIVE Circulating endothelial cells (CECs) have emerged as vascular damage markers and are increased in type 2 diabetic patients. Since type 1 diabetes is associated with vascular damage, we hypothesized high CEC numbers in this patient population. METHODS Thirty-nine patients with type 1 diabetes and 39 controls were included. CECs were isolated(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)
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)
Left atrial (LA) enlargement is a predictor of cardiovascular outcomes such as atrial fibrillation (AF), stroke, and death. The aim of this study was to explore the relationship between LA size and cognitive function in elderly patients without any signs of clinical dementia, AF or previous stroke. We assessed the cognitive status and LA volume (LAV) of 108(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)
BACKGROUND Activated factor XIII (FXIII) cross-links between fibrin monomers, thus increasing the clot stability and resistance to fibrinolysis. Congenital FXIII deficiency causes severe bleeding diathesis. Recently, a common polymorphism of the FXIII A subunit (FXIII Val34Leu) has been identified as a protective factor against both arterial and venous(More)
