متن کاملCorrelation of regional myocardial blood flow and function with myocardial infarct size during acute myocardial ischemia in the conscious pig.
Regional myocardial function and blood flow were determined for 48 hours after permanent occlusion of the left circumflex coronary artery in conscious swine. Systolic wall thickening and end-diastolic wall thickness (EDWTh) were correlated with regional myocardial flow (RMBF) at 15 minutes, 24 and 48 hours after occlusion. Both regional function and blood flow were compared with the extent of m...
متن کاملIncreases Myocardial Infarct Size in Rats
Background Exposure to environmental tobacco smoke (ETS) has been epidemiologically linked to death from ischemic heart disease in nonsmokers. In this study, we evaluated the influence of 3 days, 3 weeks, and 6 weeks of ETS exposure on myocardial infarct size in a rat ischemia/reperfusion model. Methods and Results Sprague-Dawley rats exposed to ETS (four Marlboro cigarettes per 15 minutes, 6 h...
متن کاملEstimation of Acute Myocardial Infarct Size
This study was performed to determine the relationship between myocardial infarct size estimated by serum CK-MB methods and the extent of irreversible injury in acute myocardial infarction. In 321 consecutive patients, infarct size was estimated by different mathematical models, and in 22 patients who died in hospital, the extent of myocardial necrosis was determined by autopsy. We also investi...
متن کاملComparative efects of nitroprusside and pinacidil on myocardial blood flow and infarct size in awake dogs with acute myocardial infarction
The effect of nitroprusside in limiting myocardial infarct was compared with that of pinacidil, a new antihypertensive agent with potent coronary vasodilator properties, in instrumented awake dogs subjected to 4 hr of left anterior descending coronary artery occlusion and 20 hr of reperfusion. Dogs were randomly assigned to receive intravenous normal saline, nitroprusside, or pinacidil beginnin...
