Troponin as a biomarker of cardiac toxicity: past, present, and future.

abstract：:Blood platelets play a fundamental role in hemostasis and thrombosis. The physiological role of platelets is to preserve the integrity of the cardiovascular system such that upon injury platelets are activated and serve to interrupt a potentially deleterious situation (i.e., hemorrhage). However, platelets are also in...
