BACKGROUND Results of experimental and clinical studies suggest that both coronary artery disease (CAD) itself and its traditional risk factors lead to endothelial dysfunction. The aim of the present study was to determine which CAD risk factors sustain their contribution to endothelial dysfunction despite the presence of established CAD. METHODS AND(More)
BACKGROUND Endothelial nitric oxide synthase produces nitric oxide which is involved in many physiologic regulatory functions. Variable number of tandem repeats in intron 4 of endothelial nitric oxide synthase gene are reported to be associated with blood pressure regulation. Nitric oxide is involved in regulation of cardiomyocyte genes but it is not known(More)
Akut abdominal aort tıkanıklığı, ölüm ile sonuçlanabileceği için, erken girişim gerektiren, sık görülmeyen bir vasküler cerrahi acil durumudur. Bu yazıda tromboza bağlı akut abdominal aort tıkanıklığı görülen ve literatür incelemesinden elde edilen verilere dayanarak, kurumsal politika çerçevesinde tedavi edilen, diyabetik ve sigara içen 44 yaşında kadın(More)
Acute myocardial infarction (AMI) in pregnancy is rare and has a high mortality rate of 37-50%. The most important risk factors are advanced maternal age, hypertension and diabetes mellitus. Although thrombolytic therapy, percutaneous transluminal coronary angioplasty (PTCA) and coronary artery by-pass grafting can be performed, primary PTCA and(More)
The left atrial appendage (LAA) function was evaluated in patients with severe rheumatic mitral regurgitation, having sinus rhythm or atrial fibrillation, by standard and tissue Doppler echocardiographic examinations. Sixty patients with rheumatic severe mitral regurgitation were enrolled. The patients (14 females and 6 males) having sinus rhythm were(More)
Primary percutaneous coronary intervention (P-PCI) is the gold standard treatment for acute coronary syndromes. Plasma levels of catecholamines and other vasopressors are elevated during acute myocardial infarction (AMI) and coronary vasoconstriction is frequent. We aimed to compare the reference vessel diameter (RVD) of the infarct-related artery (IRA)(More)
It has been suggested that successful percutaneous balloon mitral valvuloplasty (PMV) decreases the intensity of spontaneous left atrial contrast, reduces the size of the left atrium, and improves left atrial function in patient with mitral stenosis. However, left atrial mechanical functions immediately after PMV have not been extensively evaluated yet. The(More)
The general recommended strategy after arterial invasive procedures is a 4- to 6-hour bed rest that is associated with patient discomfort and increased medical costs. We hypothesized that mobilization of selected patients at the second hour would not increase vascular complications. Coronary angiography was performed through the femoral route via 6-Fr(More)
Prolonged QRS duration is the main selection criterion for cardiac resynchronization therapy (CRT) which ameliorates left ventricular mechanical dyssynchrony (MD). However, consequences of post-CRT QRS prolongation and residual MD have been poorly evaluated. We aimed to define the predictors of persistent MD and hypothesized that CRT-induced QRS change(More)
The left main coronary angiography (LMCA) ranges from 3 to 6 mm in diameter and may be up to 10 to 15 mm in length in humans. We here report a case of the longest LMCA (38 mm) in a 60-year-old woman with subacute anterior myocardial infarction. In coronary angiography and coronary computerized tomography LMCA was measured to be 38 mm long.
