• Reflex mechanisms affecting the coronary circulation have been postulated and described as participating in the profound fall in blood pressure frequently attending cardiogenic shock following acute coxxmary occlusion. The reflex mechanisms suggested as being responsible for potentiating the cause of sudden death in coronary artery disease are: (1) an intercoronary reflex, which is believed t...

Introduction C total coronary occlusion remains one of the limitations of percutaneous transluminal coronary angioplasty, and few therapeutic devices are specifically designed to address this problem. Despite advances in device technology, the management of resistant, calcific lesions remains one of the greatest challenges in successful chronic total coronary occlusion intervention. Established...

AD, anterior descending coronary artery; CTO, chronic total occlusion; CX, circumflex coronary artery; F, female; LMC, left main coronary artery; M, male; RC, right coronary artery. a Patient no. 4 had chronic renal failure requiring hemodialysis, as well as severe peripheral arterial disease. Patient no. 7 had advanced chronic obstructive pulmonary disease. b Patient no. 4 had total occlusion ...

Acute left anterior descending coronary artery occlusion was produced in 21 conscious, chronically instrumented dogs. Forty minutes after coronary occlusion, nine dogs were given i.v. teprotide, 25 ,ug/kg/min, followed by oral doses of captopril, 10 mg/kg every 8 hours for 24 hours. The remaining 12 dogs served as saline-infused controls. In all dogs, acute coronary occlusion increased plasma r...

Heart rates (HR) were measured before (control HR) and after (ischemic HR) balloon inflation during percutaneous transluminal coronary angioplasty in 96 patients with effort angina pectoris. The delta HR, defined as (ischemic HR-control HR), in the right coronary artery occlusion was significantly smaller than that in the left anterior descending artery or left circumflex artery occlusion. Amon...

BACKGROUND Coronary artery hemostasis during offpump coronary artery bypass (OPCAB) may be achieved with extraluminal coronary occlusion or intraluminal coronary shunting. We sought to determine with a normal porcine beating-heart model whether coronary shunting preserves regional myocardial perfusion and function compared with coronary occlusion. METHODS Six pigs (50-60 kg) underwent sternot...

Although acute left main coronary artery occlusion is rare, it carries a very high mortality rate. Following the encouraging results of trials testing the effect of primary percutaneous coronary intervention, more cases of left main stenosis are treated as culprit lesion in acute myocardial infarction. Few cases of primary percutaneous intervention on left main occlusion have been published. We...

Recently a potent anti-inflammatory effect of hydroalcoholic extract of the aerial parts of the sterile stems of Stachys inflata has been reported. This study examined whether hydroalcoholic extract isolated from aerial parts of non-flowering stems of Stachys inflata (standardized to contain 4.5% caffeic acid derivatives) reduce myocardial infarct size arising from coronary artery occlusion (30...
