Coronary Spasm Preferentially Occurs at Branch Points
Background –Coronary spasm plays an important role in the pathogenesis of ischemic heart disease. However, similarities and differences between coronary spasm and atherosclerosis are not known. We examined the angiographic characteristics of coronary spasm in comparison with those of atherosclerosis. Methods and Results –Thirty two left anterior descending (LAD), 11 left circumflex (LCx) and 23...

BACKGROUND Coronary spasm plays an important role in the pathogenesis of ischemic heart disease. However, similarities and differences between coronary spasm and atherosclerosis are not known. We examined the angiographic characteristics of coronary spasm in comparison with those of atherosclerosis. METHODS AND RESULTS Thirty-two left anterior descending arteries, 11 left circumflex arteries,...
متن کاملEarly evidence of endothelial vasodilator dysfunction at coronary branch points.
Intracoronary acetylcholine produces endothelium-dependent dilation of normal coronary arteries and paradoxical constriction of atherosclerotic vessels. Regional differences in endothelium-dependent vasomotion, however, have not been studied in relation to the nonuniform development of atherosclerosis. We compared the vasomotor response to increasing doses of acetylcholine of angiographically s...
متن کاملCoronary Circulation After Coronary Spasm
To examine whether acute myocardial ischemia activates the coagulation system and platelet activation in the coronary circulation, we measured plasma levels of fibrinopeptide A and j3-thromboglobulin in the coronary sinus and the aortic root simultaneously in 15 patients with coronary spastic angina before and after the left coronary spasm induced by intracoronary injection of acetylcholine and...
متن کاملMultivessel coronary artery spasm.
A 60-year-old patient with variant angina was shown to have myocardial ischemia in two different regions supplied by separate major coronary arteries. Neither artery had significant coronary atherosclerotic obstruction. Ventricular fibrillation was noted during ST-segment elevation in anteroseptal leads. The attacks of pain and arrhythmias disappeared during nifedipine therapy.
