Between April 2019 and April 2021, a total of 150 patients were randomized to receive either empagliflozin or placebo at 31 centers in Japan. In men, the rate of ventricular arrhythmia events was significantly lower in the empagliflozin group than in the placebo group, with a rate ratio of 0.33 (95% CI: 0.27-0.39; P < 0.001). In women, the rate ratio was 1.78 (95% CI: 0.54-5.90; P = 0.35), with no statistically significant difference observed. Notably, a significant interaction between sex and treatment was observed, suggesting a sex-specific treatment response (P = 0.006) CONCLUSIONS: The arrhythmic effect of empagliflozin in patients with T2DM treated with ICDs appears to be more pronounced in men than in women. These findings underscore the need for investigating sex-specific responses to sodium-glucose cotransporter 2 inhibitors, advancing personalized strategies for arrhythmia management.
