Cardiac hypertrophy is characterized by a growth in cardiomyocyte size and thickening of the ventriculur walls. It is the heart's response to increased workload, a heart attack or genetic mutation. Initially, such an increase is an adaptive response to maintain cardiac function. However, in constant stress situations and as time progresses, these changes become non-adaptive and eventually heart fails. Hypertension or high blood pressure is one of the most important risk factors of heart failure. The condition in which the heart is unable to pump an adequate supply of blood to the body is termed as heart failure. This book unravels the recent studies on cardiac hypertrophy and heart failure. It presents researches and studies performed by experts across the globe. This book includes some of the vital pieces of work being conducted across the world, on various topics related to cardiac hypertrophy and heart failure.
