Case presentation A: A 50-year-old diabetic man presented to the hospital after 8 hours of continuous chest pain. Because of acute myocardial infarction of the anterior wall, he underwent direct stenting to an occlusion in the left anterior descending coronary artery. Despite revascularization, suboptimal coronary flow was achieved, and he subsequently developed heart failure. Case presentation...

To try to unravel the complexity and heterogeneity of the "no-reflow" phenomenon and its underlying mechanisms, we studied tissue perfusion in reperfused heart muscle by using tracer microspheres in an anesthetized dog model of 90-minute coronary occlusion followed by reperfusion for 2 1/2 hours, 24 hours, or 1 week. Regional myocardial blood flow was determined both in basal flow conditions an...

ne of the corporate goals at AT&T is to eliminate chloroflurocarbons (CFCs) from its manufacturing operations by the end of 1994. Many alternatives have been implemented to meet this objective, including noclean wave soldering using low-solids flux, aqueous cleaning of water-soluble flux, aqueous cleaning with saponifiers and semiaqueous (terpene) cleaning. Part 1 of this article describes the ...

BACKGROUND AND PURPOSE While polymorphonuclear leukocytes may contribute to the "no-reflow" phenomenon after focal cardiac and skeletal muscle ischemia/reperfusion, their contribution to acute focal cerebral ischemia is unresolved. We have examined the role of polymorphonuclear leukocytes in microvascular perfusion defects after focal cerebral ischemia/reperfusion in a baboon model of reversibl...
