Coronary Artery Stenosis
Background. Nitroglycerin is effective in relieving myocardial ischemia; however, intracoronary nitroglycerin often fails to relieve angina and has been reported to have deleterious effects on subendocardial blood flow. To understand the mechanisms involved, we evaluated the direct effect of nitroglycerin on coronary circulation of the ischemic hearts. Methods and Results. We measured the phasi...
متن کاملLeft main coronary artery stenosis.
Between 1 January, 1989, and 28 April, 1990, a total of 888 selective coronary arteriographies were performed at the Institute for Clinical and Experimental Medicine in Prague. Of that number, 58 findings were assessed as at least 50% stenosis of the left main coronary artery (LCA). Having applied exclusion criteria, 50 patients (i.e., 5.63% of all those examined) were entered into a retrospect...
متن کاملLeft Main Coronary Artery Stenosis
A retrospective study was carried out in 114 unoperated and 197 operated patients having left main coronary artery (LMCA) stenosis 2 50%. Including the operative mortality of 9.1%, survival at seven years was significantly greater following pure aortocoronary bypass graft surgery, 77.5% as compared to 48.5% for the unoperated patients (P < 0.01). The surgical mortality was significantly less du...
متن کاملCoronary Artery Calcium Score Improves the Prediction of Occult Coronary Artery Stenosis in Ischemic Stroke Patients
BACKGROUND Coronary heart disease is a significant cause of morbidity and mortality in stroke patients. The coronary artery calcium score (CACS) has emerged as a robust and noninvasive predictor of coronary events. We assessed the predictive ability of CACS to identify stroke patients with severe (≥50%) occult coronary artery stenosis in a stroke/transient ischemic attack population, in additio...
متن کاملFluid dynamics of coronary artery stenosis.
A large-scale model of the coronary circulation, instrumented to permit detailed pressure and velocity measurements, has been used to study flow through isolated stenotic elements in large coronary arteries. Pulsatile aortic and instantaneous peripheral resistance were stimulated with servovalves. A variety of axisymmetric and asymmetric stenoses were studied and flow separation was found to oc...
