Coronary atherosclerotic plaques may restrict coronary blood flow producing angina or rupture causing unstable angina, myocardial infarction or sudden death. The rupture prone plaques are lipid rich, have thin fibrous caps and are often angiographically mild. Most treatment strategies are focused on relieving cardiac symptoms or salvaging myocardium in the ...
