Background : We sought to compare the outcomes of patients receiving combination therapy of diuretics and neurohormonal blockers, with a matched cohort with monotherapy of loop diuretics, using real-world big data. Methods : This study was based on the Diagnosis Procedure Combination database in the Japanese Registry of All Cardiac and Vascular Datasets (JROAD-DPC). After exclusion criteria, we identified 78,685 patients who were first hospitalized with heart failure (HF) between April 2015 and March 2017. Propensity score (PS) was estimated with logistic regression model, with neurohormonal blockers (angiotensin-converting enzyme inhibitor : ACEi or angiotensin receptor blocker : ARB, ?-blockers and mineralocorticoid receptor antagonists : MRA) as the dependent variable and 24 clinically relevant covariates to compare the in-hospital mortality between monotherapy of loop diuretics and combination therapies. Results : On PS-matched analysis, patients with ACEi?/?ARB, ?-blockers, and MRA had lower total in-hospital mortality and in-hospital mortality within 7 days, 14 days and 30 days. In the sub-group analysis, regardless of clinical characteristics including elderly people and cancer, patients treated with a combination of loop diuretics and neurohormonal blockers had significantly lower in-hospital mortality than matched patients. Conclusions : Our data indicate the benefits of guideline-directed medical therapy to loop diuretics in the management of HF. J. Med. Invest. 70 : 41-53, February, 2023
