| pubmed-article:2242540 | pubmed:abstractText | The loss of coronary vasodilator reserve after ischemia-reperfusion may be due to endothelial injury, and this vascular dysfunction may contribute to functional alterations observed after ischemia. To determine whether endothelial dysfunction occurs after relatively brief periods of moderate low-flow ischemia in vivo, open-chest swine were subjected to 15 minutes of critical, subtotal left anterior descending coronary artery occlusion (80%) followed by 60 minutes of reperfusion. Serial measurements of regional coronary flow were made with the radiolabeled microsphere technique. After 60 minutes of reperfusion, the left anterior descending coronary artery was excised together with a section of the normally perfused left circumflex coronary artery to examine in vitro the relaxations to the endothelium-dependent dilators ADP and bradykinin and to the endothelial-independent dilators sodium nitroprusside and adenosine. Contractions to serotonin in quiescent rings were also examined. Endocardial and transmural blood flows recovered to preocclusion levels within 60 minutes of reperfusion, as did the epicardial-to-endocardial ratio. Vascular responses in isolated, reperfused left anterior descending coronary artery rings were significantly different from responses in control left circumflex coronary artery rings. Endothelium-dependent relaxations to adenosine diphosphate and bradykinin were significantly depressed in the left anterior descending coronary artery rings compared with left circumflex coronary artery rings (p less than 0.05). Serotonin-induced contractions were significantly greater in occluded-reperfused left anterior descending than in left circumflex coronary arteries (p less than 0.05). Relaxations to adenosine and sodium nitroprusside were not significantly different between the two groups.(ABSTRACT TRUNCATED AT 250 WORDS) | lld:pubmed |
