To compare global Left Ventricular (LV) systolic function assessment by 16-detector row Computed Tomography (MDCT) with Two-Dimensional Standard Echocardiography (2DSE) in a routine cardiology practice setting and to ascertain the degree of correlation between LV volumes and measurements obtained by 2DSE with those measured by MDCT. In 52 patients with(More)
BACKGROUND The 3-hydroxy-3-methylglutaryl-CoA reductase inhibitors (statins) reduce serum cholesterol level and cardiovascular morbidity and mortality. However, the effect of statins on glucose metabolism is unclear. Some studies have suggested that statins may cause hyperglycemia by increasing calcium concentration in the islet cells leading to decrease in(More)
Recent studies have suggested that proton pump inhibitors (PPIs) attenuate the benefits of clopidogrel. The clinical relevance of this interaction in patients who have undergone percutaneous coronary intervention (PCI) is unknown. We hypothesized that post-PCI patients discharged on clopidogrel will have higher cardiovascular events if concomitant PPI(More)
Haematemesis and malena are the two most important symptoms of upper gastrointestinal bleeding. The most common cause of upper gastrointestinal bleeding is due to a peptic ulcer. In this paper, the authors research the cause of bleeding. Contrary to previous studies, results favor esophageal varices, e.g., alcoholism or cirrhosis liver post necrotic, as the(More)
Hydroxymethylglutaryl coenzyme A reductase inhibitors (statins) decrease serum cholesterol. Dyslipidemia is believed to be associated with the development of renal dysfunction. It was postulated that statins may reduce the development of renal dysfunction. The effect of statin use on the development of renal dysfunction in 197,551 patients (Department of(More)
BACKGROUND/OBJECTIVE In this era of drug eluting stents (DES), the long-term outcome of percutaneous intervention (PCI) on saphenous venous grafts (SVG) is unknown. The objective of the study was to compare the long-term outcomes of DES versus bare metal stent (BMS) in this population and to determine the predictors of outcomes. METHODS We reviewed the(More)
TWA value as positive. Although this analysis operates on this ichotomy to generate the “positive” and the “negative” response of patient to MTWA testing, thus creating a qualitative context, here is a quantitative issue as its underpinning (i.e., a patient has o reach the threshold to qualify as “positive”). Moreover, current ork indicates that the(More)
Previous reports have suggested that blacks receive life-saving cardioprotective therapies less often than whites, probably because of a lower socioeconomic status, which leads to poor access to physicians. We questioned whether racial disparity existed in the Veterans Affairs Healthcare System. We examined the Veterans' Integrated Service Network (VISN 16)(More)
BACKGROUND Cocaine causes coronary artery constriction and may cause acute myocardial infarction (AMI). The role of traditional coronary risk factors in cocaine-associated myocardial infarction is unclear. HYPOTHESIS We hypothesized that traditional risk factors play a major role in predicting AMI in patients admitted with cocaine-associated chest pain (More)
OBJECTIVE To determine the feasibility of a hybrid coronary revascularization (HCR) approach for the treatment of left main (LM) coronary artery stenosis. BACKGROUND The recommended therapy for significant LM stenosis is coronary artery bypass grafting (CABG). Percutaneous coronary intervention (PCI) of unprotected LM lesions is reserved for patients at(More)
