Heart failure is a serious condition caused by the heart failing to pump enough blood around the body at the right pressure. It usually occurs because the heart muscle has become too weak or stiff to work properly, most commonly caused by heart attack, high blood pressure or cardiomyopathy (heart disease). This book is a comprehensive guide to heart failure for clinicians. Divided into six sections, the book begins with emergency management, then discusses heart failure in both in-patient and out-patient hospital care. A complete chapter is dedicated to the role of biomarkers at different stages of heart failure.
