Abstract
- Beta-blocker (BB) therapy is a main pillar in treating patients with heart failure and reduced ejection fraction and has shown a prognostic benefit. However, evidence for application of BB in heart failure with preserved ejection fraction (HFpEF), especially in the absence of coronary artery disease, atrial fibrillation or arterial hypertension, is scarce. HFpEF is characterized by elevations in left atrial pressure and reduced compliance of the left ventricle leading to a hampered increase of cardiac output (CO) during exercise, which results in exertional dyspnea. This may be due to either a limited increase in stroke volume or reduced chronotropy during physical activity. We critically discuss the pathophysiological background of HFpEF, current data on BB in heart failure therapy, as well as the potential benefits and harms of BB therapy in HFpEF. Furthermore, we argue that non-cardio selective BB with peripheral activity to reduce afterload may be more suitable in this population than cardio-selective BB. Although preliminary data on BB in HFpEF are available, multicenter prospective trials to assess a reduction of cardiovascular morbidity are warranted. Future trials need to focus on phenotyping HFpEF patients and assess who may benefit most from tailored BB therapy. [ABSTRACT FROM AUTHOR]
