Abstract

High-risk acute coronary syndrome is characterized by vulnerable-plaque with subocclusive thrombus and down-stream microemboli spreading minor myocardial damage, resulting in non-ST-elevation myocardial infarction. Advances in the understanding of the pathogenesis and consequences of acute coronary syndrome have stimulated development of novel biomarkers, and expanded their role in the different spectrum of the underlying pathophysiology, namely multi-biomarker strategy; consisted of biomarkers for 1) myocardial necrosis(membrane damage to myofibril necrosis), 2) plaque destabilization, 3) myocardial stress(ischemic stress per se and end-diastolic atrial or ventricular wall stress), 4) myocardial ischemia, and 5) inflammatory process. In this article, we review clinical importance of novel biomarkers referring our previous clinical investigation and other reports, especially troponin T for detection of minor myocardial damage associated with vulnerable plaque with thrombus/embolus, heart-type fatty acid -binding protein for earlier detection of myocardial damage and it's role for the rule-out triage, N-terminal pro-BNP for earlier risk stratification in cardiac emergency, and soluble CD40 ligand for earlier identification of pl...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
