Provoked coronary spasm and acute coronary syndromes.
lthough coronary artery spasm (CAS) has been linked ith acute coronary syndromes (ACS) and vulnerable laque (1), thrombosis (2), percutaneous coronary intervenion (PCI), and stenting (3–7), very limited attention is iven to CAS in the current era. This may be related to ssumptions that the frequency of CAS is decreasing and if resent it will be eliminated with calcium antagonist (8) or itrate u...
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 کاملPathophysiology of Coronary Thrombus Formation and Adverse Consequences of Thrombus During PCI
Atherosclerosis is a systemic vascular pathology that is preceded by endothelial dysfunction. Vascular inflammation "fuels" atherosclerosis and creates the milieu for episodes of intravascular thromboses. Thrombotic events in the coronary vasculature may lead to asymptomatic progression of atherosclerosis or could manifest as acute coronary syndromes or even sudden cardiac death. Thrombus encou...
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.
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...
