OBJECTIVES The present analysis was performed to evaluate the impact of diabetes mellitus (DM) status on the severity of coronary artery disease (CAD) and current approaches in interventional treatment. BACKGROUND Little is known about the effect of DM treated with diet, oral agents, or insulin on lesion characteristics and anatomical pattern of CAD and their interventional treatment. METHO...
Angiographically determined changes in segmental wall motion (SWM) and ejection fraction (EF) are sensitive indices of left ventricular (LV) function. To compare the effects of exercise on LV function, first pass radionticlide angiocardiography was used before and during maximal upright bicycle stress in patients with nonsignificantly stenosed coronary arteries, and in those with > 75% stenosis...

Percutaneous transluminal balloon angioplasty was attempted in seven patients with internal carotid artery stenosis, including one patient who had two procedures. All had recurrent, carotid territory, neurological symptoms considered haemodynamic in origin. Six had occlusion of the contralateral internal carotid artery. Cerebral blood flow studies confirmed diminished cerebrovascular reserve in...
BACKGROUND The purpose of this study was to determine the ability of blood oxygen level dependent (BOLD) cardiovascular magnetic resonance (CMR) to detect stress-inducible myocardial ischemic reactions in the presence of angiographically significant coronary artery disease (CAD). METHODS Forty-six patients (34 men; age 65 ± 9 years,) with suspected or known coronary artery disease underwent C...
We report two rare cases of an anomalous origin of the left pulmonary artery (AOLPA) from the ascending aorta, associated with pulmonary atresia, a ventricular septal defect and a left aortic arch. The cases are unusual because AOLPA is more commonly associated with a right aortic arch and it is more usual for the right pulmonary artery to originate anomalously from the ascending aorta. The pul...
cardiovascular diseases are one of the most common diseases that cause a large number of deaths each year. coronary artery disease (cad) is the most common type of these diseases worldwide and is the main reason of heart attacks. thus early diagnosis of cad is very essential and is an important field of medical studies. many methods are used to diagnose cad so far. these methods reduce cost and...
