title: Treatment of diastolic dysfunction in hypertension.
abstract: Diastolic dysfunction is present in half of patients with hypertension and has been shown to be associated with increased cardiovascular morbidity and mortality, as well as the development of heart failure. With the high prevalence of hypertension and its associated complications, treatment of diastolic dysfunction in hypertension is an important and desirable goal. Angiotensin converting enzyme inhibitors and angiotensin receptor blockers have been shown to be effective in improvement of measures of diastolic function and are recommended as first-line agents in the control of hypertension in patients with diastolic heart failure. Beta-blockers, calcium channel blockers, and diuretics have also shown some efficacy in improved indices of diastolic filling. However, the independent impact of these pharmacologic interventions on prognosis and outcome in diastolic dysfunction has yet to be clarified. The Irbesartan in Heart Failure with Preserved Ejection Fraction (I-PRESERVE) study, Candesartan in Heart Failure: Assessment in Reduction of Mortality and Morbidity (CHARM-Preserved) trial and the Losartan Intervention For End-point Reduction in Hypertension (LIFE) Study all failed to show improved morbidity and mortality with these drugs although, the LIFE study showed reduced heart failure hospitalization in hypertensive patients with normal in-treatment diastolic function. The Trial Of Preserved Cardiac function heart failure with an Aldosterone anTagonist (TOPCAT) is an on-going large, international study evaluating the effect of spironolactone on cardiovascular mortality, aborted cardiac arrest, or hospitalization for diastolic heart failure. This and other studies will provide further insight into the pathophysiology and management of patients with diastolic dysfunction.
