Beta-Blockers in Heart Failure with Preserved Ejection Fraction: Could Their Use Be Vindicated as an Acceptable Option in the Future Treatment Guideline?

Current Status of Pharmacologic and Nonpharmacologic Therapy in Heart Failure with Preserved Ejection Fraction

Heart failure with preserved ejection fraction (HFpEF) is a significantly symptomatic disease and has a poor prognosis similar to that of heart failure with reduced ejection fraction (HFrEF). Contrary to HFrEF, HFpEF is difficult to diagnose, and the recommended diagnostic algorithm of HFpEF is complicated. Several therapies for HFpEF have failed to reduce mortality or morbidity. HFpEF is thought to be a complex and heterogeneous systemic disorder that has various phenotypes and multiple comorbidities. Therefore, therapeutic strategies of HFpEF need to change depending on the phenotype of the patient. This review highlights the pharmacologic and nonpharmacologic treatment of HFpEF.

Therapeutic Properties of Highly Selective β-blockers With or Without Additional Vasodilator Properties: Focus on Bisoprolol and Nebivolol in Patients With Cardiovascular Disease

Bisoprolol and nebivolol are highly selective β₁-adrenoceptor antagonists, with clinical indications in many countries within the management of heart failure with reduced left ventricular ejection fraction (HFrEF), ischaemic heart disease (IHD), and hypertension. Nebivolol has additional vasodilator actions, related to enhanced release of NO in the vascular wall. In principle, this additional mechanism compared with bisoprolol might lead to more potent vasodilatation, which in turn might influence the effectiveness of nebivolol in the management of HFrEF, IHD and hypertension. In this article, we review the therapeutic properties of bisoprolol and nebivolol, as representatives of “second generation” and “third generation” β-blockers, respectively. Although head-to-head trials are largely lacking, there is no clear indication from published studies of an additional effect of nebivolol on clinical outcomes in patients with HFrEF or the magnitude of reductions of BP in patients with hypertension.

Heart failure with preserved ejection fraction: insights from recent clinical researches

Heart failure (HF) with preserved ejection fraction (HFpEF) accounts for nearly half of the cases of HF and its incidence might be increasing with the aging society. Patients with HFpEF present with significant symptoms, including exercise intolerance, impaired quality of life, and have a poor prognosis as well as frequent hospitalization and increased mortality compared with HF with reduced ejection fraction. The concept of HFpEF is still evolving and may be a virtual complex rather than a real systemic disorder. Thus, beyond solely targeting cardiac abnormalities management strategies need to be extended, such as left ventricular diastolic dysfunction. In this review, we examine new diagnostic algorithms, pathophysiology, current management status, and ongoing trials based on heterogeneous pathophysiology and etiology in HFpEF.
