Clinical and Molecular Aspects of Cardiomyopathies: Emerging Therapies and Clinical Trials.

Cardiomyopathies are diseases of the myocardium, often genetically determined, associated with heterogeneous phenotypes and clinical manifestations. Despite significant progress in the understanding of these conditions, available treatments mostly target late complications, whereas approaches that promise to interfere with the primary mechanisms and natural history are just beginning to surface. The last decade has witnessed the establishment of large international cardiomyopathy registries, paralleled by advances in cardiac imaging and genetic testing, deeper understanding of the pathophysiology and growing involvement by the pharmaceutical industry. As a result, the number of molecular interventions under scrutiny is increasing sharply.
