High-impact articles related to the pharmacotherapeutic management of systolic heart failure.

This compilation is part of a series of five articles identifying important literature in cardiovascular pharmacotherapy. This list focuses on pharmacotherapeutic management of acute decompensated and chronic heart failure. Most of the cited works present the results of landmark clinical studies that have shaped the management of patients with left ventricular systolic dysfunction.

Clopidogrel-induced thrombotic thrombocytopenic purpura-hemolytic uremic syndrome after coronary artery stenting.

The antiplatelet drug clopidogrel has largely replaced ticlopidine, due to an association between ticlopidine and thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS). Clopidogrel at first was thought to be void of this potentially fatal adverse effect, but recent case reports have called that assumption into question. Even with proper treatment (plasma exchange), TTP-HUS can persist for weeks.
