This book is part of the AHA Clinical Series published in conjunction with the American Heart Association in order to focus on high-interest and emerging topics in cardiovascular disease targeted for cardiologists and other interested healthcare providers. Cardiogenic shock causes over half of the deaths among patients hospitalized with ST-elevation myocardial infarction worldwide. Therefore, its management is one of the most important aspects of the care of patients with acute MI. Yet there is no single comprehensive source for information about this problem in the modern era; this book fills that gap. Drs. Hochman and Ohman offer an extremely useful tool for investigating, evaluating, and treating one of the most important lingering challenges in acute cardiovascular care. © 2009 American Heart Association.
