UNLABELLED Our aim was to determine the value of vasodilator left ventricular ejection fraction (LVEF) reserve (stress ejection fraction - rest ejection fraction) in evaluating the magnitude of myocardium at risk and the anatomic extent of underlying severe coronary artery disease (CAD). METHODS We studied 510 consecutive patients with suspected CAD undergoing gated rest and vasodilator stres...

Sixteen patients, 10 with significant three-vessel coronary artery disease (>50% occlusion of each vessel) and six without coronary disease, had nutrient myocardial blood flow, cardiac output, pressure time/ min and arterial pressure determinations at rest, with atrial pacing and with right atrial pacing plus nitroglycerin. In the patients with coronary disease, nutrient myocardial blood decrea...

O coronary artery bypass (OPCAB) is a technique of performing coronary anastomosis on a beating heart without instituting cardiopulmonary bypass (CPB). Coronary stabilizers (CS) are used for local cardiac wall immobilization and access to the heart can be achieved by a lateral, anterolateral, subxyphoidal or midsternal incision. With median sternotomy and use of CS, all sides of the heart can b...

Current treatment strategies for multi-vessel coronary artery disease include either coronary artery bypass surgery or percutaneous coronary intervention with stenting. The present study evaluates the morbidity and mortality among coronary artery disease patients undergoing triplevessel angioplasty. This prospective record based descriptive study was carried out in Medical College, Pariyaram, K...

Glycoprotein IIb/IIIa (GP IIb/IIIa) inhibitors were developed in the early 1990’s with the purpose of providing maximum platelet aggregation blockade. At first they were used adjunctly with balloon coronary angioplasty to reduce acute occlusion of the vessel treated and its complications such as periprocedural acute myocardial infarction (MI). The dissection of the vessel after balloon dilation...

Two hundred and sixteen patients with acute myocardial infarction were treated with immediate infusion of high-dose (1.5 million units) intravenous streptokinase followed by emergency coronary angioplasty. The infarct lesion was crossed and dilated in 99% and persistent coronary perfusion after the procedure was achieved in 90% (including 3% with significant residual stenosis). Total in-hospita...

BACKGROUND Chemerin is a novel adipokine that is associated with inflammation and adipogenesis. However, it remains unclear whether chemerin is involved in patients with cardiovascular disease. We investigated whether the serum chemerin levels of Korean patients with coronary artery disease correlated with specific cardiometabolic parameters. METHODS In total, 131 patients, all of whom had co...

Background Vessel wall inflammation plays a key role in the initiation and progression of atherosclerosis, from endothelial injury to remodeling and plaque formation. Cardiovascular (CV) magnetic resonance (CMR) provides noninvasive visualization and characterization of arterial remodeling both in the great vessels, and also the coronary arteries. Contrast-enhanced inversion-recovery (CEIR) pre...

Background The aim for ultrahigh field coronary MR angiography (MRA) is to convert the benefit of increased signal-tonoise ratio (SNR) to improved spatial resolution and thereby better vessel edge sharpness (VES), while vessel conspicuity is preserved. Furthermore, black blood coronary MRA has been shown to be an alternative technique to detect arterial remodeling in patients with coronary arte...
