Idiopathic Cardiomyopathy.

Idiopathic cardiomyopathy is a very common cause of heart failure today. It is a diagnosis of exclusion, and careful attention should be paid to the patient history to exclude all other causes. ACE inhibitors have become the first line therapy for all classes of left ventricular dysfunction. Doses of all therapeutic drugs for CHF should be up-titrated to maximum targeted dosages. New agents are being developed that offer increasing hope for therapies that will alter the natural history of heart failure.
