Diastolic dysfunction and heart failure with preserved ejection fraction: rationale for RAAS antagonist/CCB combination therapy

Academic Article

Abstract

  • A large number of patients who present with signs or symptoms of heart failure (HF) do not have evidence of left ventricular systolic dysfunction. As a result, HF in the presence of normal or preserved ejection fraction, or diastolic HF, is increasingly recognized as a health care challenge. Guidelines have been issued for the classification, diagnosis, and prevention of HF from diastolic dysfunction, but treatment of this condition remains problematic. Antihypertensive agents that have been proven in clinical trials to improve outcomes in HF with systolic dysfunction, such as angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and β-blockers, have not yet demonstrated comparable benefits in patients with diastolic dysfunction. Combination therapy using an antagonist of the renin-angiotensin-aldosterone system and a calcium-channel blocker has potential advantages over monotherapy and is being explored in several ongoing clinical trials. © 2009 American Society of Hypertension.
