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.
متن کاملCoronary Artery Spasm and Vasoconstriction
It is now generally accepted that an episodic increase of the vasomotor tone of epicardial coronary arteries not only is the cause of variant angina but also may represent a pathogenetic component in other, more common, anginal syndromes.1,2 The terms "spasm" and "coronary constriction" are often used interchangeably when referring to increases in coronary vasomotor tone. This generalization ma...
