Treatment of hypertension for patients with diastolic dysfunction.

Diastolic dysfunction is a poorly understood pathophysiological entity; its importance is magnified by the increasing prevalence of diastolic heart failure. Forty-six million people in the US are experiencing heart failure and 550000 new cases are diagnosed annually. A large percentage of these patients with heart failure have a normal or nearly normal left-ventricular ejection fraction. Isolated diastolic dysfunction may be associated with an increased mortality. One of the major causes of diastolic dysfunction is hypertension. Advances in diagnosis and treatment strategies may improve the clinical outcome for patients with diastolic dysfunction.
