Abstract | BACKGROUND: METHODS: This trial was a prospective multicenter study of 58 T2DM patients with stable HF at five institutions in Japan. Patients who had been taking at least one antidiabetic drugs other than SGLT2 inhibitors started the administration of 5 mg/day of dapagliflozin. The physical examinations, blood tests, and echocardiography were performed at baseline and 6 months after administration of dapagliflozin. The primary endpoint was defined as a change in mitral inflow E and mitral e' annular velocities (E/e') between baseline and 6 months after the administration of dapagliflozin. The secondary end points consisted of a change in brain natriuretic peptide (BNP), LV mass index (LVMI) and left atrial volume index (LAVI). RESULTS: E/e' significantly decreased from 9.3 to 8.5 cm/s (p = 0.020) 6 months after administration of dapagliflozin. LAVI and LVMI significantly decreased from 31 to 26 mL/m2 (p = 0.001), and from 75.0 to 67.0 g/m2 (p < 0.001), respectively, 6 months after administration of dapagliflozin. No significant change was observed in BNP (from 27.9 to 28.9 pg/mL; p = 0.132) 6 months after administration of dapagliflozin, except for a significant decrease from 168.8 to 114.3 pg/mL (p = 0.012) in patients with BNP ≥ 100 pg/mL. CONCLUSION: This prospective multicenter trial showed the beneficial effect of SGLT2 inhibitors on LV diastolic functional parameters for T2DM patients with HF. Our findings may thus offer a new insight into the management of T2DM patients.
