Opis

Pathophysiology of Heart Failure brings together leading basic scientists and clinicians, presenting new approaches to this complex problem, involving cardiomyopathic processes and ischemia perfusion injury. The result is a synthesis of state-of-the-art information on molecular biology, cellular physiology and structure-function relationships in the cardiovascular system. The role which excess intracellular calcium plays in the genesis of cardiac dysfunction is described as a fundamental mechanism underlying heart failure; one which may lead to improved prevention and treatment.
Audience: Clinical and experimental cardiologists will find the book a helpful source of ideas and inspiration.
