RESUMEN
Heart failure with preserved ejection fraction (HFpEF) is rapidly growing as the most common form of heart failure. Among HFpEF phenotypes, the cardiometabolic/obese HFpEF - HFpEF driven by cardiometabolic alterations - emerges as one of the most prevalent forms of this syndrome and the one on which recent therapeutic success have been made. Indeed, pharmacological approaches with sodium-glucose cotransporter type 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) have proved to be effective due to metabolic protective effects. Similarly, lifestyle changes, including diet and exercise are crucial in HFpEF management. Increasing evidence supports the important role of diet and physical activity in the pathogenesis, prognosis, and potential reversal of HFpEF. Metabolic derangements and systemic inflammation are key features of HFpEF and represent the main targets of lifestyle interventions. However, the underlying mechanisms of the beneficial effects of these interventions in HFpEF are incompletely understood. Hence, there is an unmet need of tailored lifestyle intervention modalities for patients with HFpEF. Here we present the current available evidence on lifestyle interventions in HFpEF management and therapeutics, discussing their modalities and potential mechanisms.
RESUMEN
PURPOSE OF REVIEW: Incretin-based drugs are potent weight-lowering agents, emerging as potential breakthrough therapy for the treatment of obesity-related phenotype of heart failure with preserved ejection fraction (HFpEF). In this review article, we will discuss the contribution of weight loss as part of the benefits of incretin-based medications in obese patients with HFpEF. Furthermore, we will describe the potential effects of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists on the heart, particularly in relation to HFpEF pathophysiology. RECENT FINDINGS: In the STEP-HFpEF trial, the GLP-1 receptor agonist semaglutide significantly improved quality of life outcomes in obese HFpEF patients. Whether the beneficial effects of semaglutide in obese patients with HFpEF are merely a consequence of body weight reduction is unclear. Considering the availability of other weight loss strategies (e.g., caloric restriction, exercise training, bariatric surgery) to be used in obese HFpEF patients, answering this question is crucial to provide tailored therapeutic options in these subjects. SUMMARY: Incretin-based drugs may represent a milestone in the treatment of obesity in HFpEF. Elucidating the contribution of weight loss in the overall benefit observed with these drugs is critical in the management of obese HFpEF patients, considering that other weight-lowering strategies are available and might represent potential alternative options for these patients.
