Despite the poor prognosis of HFrEF, the sodium-glucose cotransporter 2 inhibitor (SGLT2i) dapagliflozin may help reduce the risk of death caused by ventricular arrhythmias.
Introduction Despite the progress made in the treatment of heart failure with reduced ejection fraction (HFrEF) in recent years, the prognosis of the disease remains poor, with ventricular arrhythmias (VA) contributing significantly to increased mortality. Areas covered A recently published post hoc analysis of the DAPA-HF trial evaluated the effect of the sodium-glucose cotransporter 2 inhibitor (SGLT2i) dapagliflozin versus placebo on the incidence of VA, resuscitated cardiac arrest, or sudden death among people with HFrEF. During a median follow-up of 18.2 months, the composite primary outcome occurred in 140 (5.9%) people who received dapagliflozin compared to 175 (7.4%) participants in the placebo arm (hazard ratio 0.79; 95 confidence interval 0.63-0.99, P = 0.037). Animal studies suggest that SGLT2i could ameliorate the deleterious effects of myocardial injury, through various mechanisms, including reduced sympathetic activity, improved oxidative stress, tissue oxygenation, autophagy, heart energy metabolism, and promotion of cardiac remodeling. Expert opinion Taken together, the above findings indicate a place for SGLT2i in future trials investigating novel treatments to improve survival in patients with acute cardiovascular episodes. This is primarily applicable for acute decompensated HF; however, their use could also be evaluated in other conditions that induce VA, such as acute coronary syndromes.
