Aims Few studies have reported the impact of high‐dose loop diuretics at discharge on prognosis in Japanese patients with heart failure (HF). Our purpose was to assess the relationship between the dose of loop diuretics at discharge and cardiovascular mortality in patients with HF. Methods and results We enrolled decompensated HF patients who were admitted to our hospital between March 2010 and March 2015, and compared HF patients who received high‐dose loop diuretics at discharge (HD group) with low‐dose loop diuretics at discharge (LD group) with regard to risk of cardiovascular mortality, and all‐cause mortality. High‐dose loop diuretic was defined as ≥40 mg/day of oral furosemide at discharge. A total of 215 patients were enrolled to the study. The median follow‐up duration was 641 days. All‐cause and cardiovascular mortality were significantly lower in the LD group than in the HD group (10.4% vs. 31.6%, P < 0.001; 2.2% vs. 24.6%, P < 0.001, respectively). High‐dose loop diuretics were associated with cardiovascular mortality in multivariate Cox proportional hazards model (hazard ratio, 16.06, 95% confidence interval 3.457 to 116.8; P < 0.001). The largest area under the receiver operating characteristic curve (0.85) for cardiovascular death was obtained with a threshold of 40 mg furosemide. Conclusions High‐dose loop diuretic use at discharge was one of the predictors of cardiovascular mortality in patients with HF. An oral furosemide dose of 40 mg daily may be defined as ‘high‐dose’ loop diuretics in Japanese patients with chronic HF.
