Metabolic syndrome (MetS) is a serious health condition that puts people at a higher risk of heart disease, diabetes, stroke, and atherosclerosis. Prevalent worldwide, MetS-related induced mortality and frequency contributes to the progression of heart failure, which can be controlled by proper treatment. This book identifies the echocardiographic characteristics that undergo changes in MetS, significantly affecting its course, and contributing to the clinical aggravation of the disease. This linking with echocardiography as a marker of heart failure due to MetS is useful for academics and professionals in Cardiology, Endocrinology, and Internal Medicine for effective management.
