Several clinical trials of dapagliflozin in patients with type 2 diabetes mellitus (T2DM) at elevated cardiovascular risk have observed reduced hospitalization for heart failure (HHF). Several studies have also suggested cardiovascular benefits for patients with HF regardless of whether or not they have T2DM.
This meta-analysis was conducted to evaluate the therapeutic effects of dapagliflozin in patients with HF.
The PubMed, Embase, Cochrane Library, and Web of Science databases were systematically searched from database inception to 15 February 2020. Clinical studies of dapagliflozin use in patients with HF were included. Data on HHF, all-cause mortality, cardiovascular death, major adverse cardiovascular events (MACE), systolic blood pressure, body weight, glycated hemoglobin (HbA1c), and adverse events were collected for analysis.
Four randomized controlled trials involving 6738 patients with HF were included in this meta-analysis. Patients receiving dapagliflozin showed a significantly lower incidence of HHF [risk ratio (RR) 0.72; P < 0.00001], all-cause mortality (RR 0.83; P = 0.004), cardiovascular death (RR 0.86; P = 0.03), and MACE (RR 0.88; P = 0.03). Moreover, patients receiving dapagliflozin also showed significant improvements in systolic blood pressure and body weight. However, no statistical difference was observed in HbA1c. In addition, hypoglycemia, volume depletion, and renal impairment was not more frequent with dapagliflozin than with placebo.
This meta-analysis suggests that dapagliflozin could be a therapeutic strategy for patients with HF regardless of the presence or absence of T2DM.
