| Summary: | BACKGROUND:Several randomized control trials have established that drugs can decrease the heart failure (HF) rehospitalization in patients with HF. However, limited studies have investigated the duration of medicine use to decrease the rehospitalization period in the real world. Hence, this study aims to investigate whether the evidence-based medicine decreases the HF rehospitalization in different treatment intervals in the clinical practice. METHOD:We examined patients admitted with acute HF from the National Health Insurance Research Database in Taiwan. In addition, the major adverse cardiovascular events (MACE) were the composite endpoints of the in-hospital mortality and rehospitalization after 1 year. Furthermore, we analyzed the medicine use to decrease 14 days and 1, 6, and 12 months' HF rehospitalization. RESULTS:Overall, we examined 11,012 patients. The use of the renin-angiotensin system (RAS) blockers [hazard ratio (HR), 0.58; P < 0.01], β-blocker (HR, 0.67; P < 0.01), spironolactone (HR, 0.63; P < 0.01), and digitalis (HR, 0.67; P < 0.01) associated with the lower in-hospital mortality rate. The Cox regression analysis revealed that RAS blocker (HR, 0.86; P < 0.01) and β-blocker (HR, 0.71; P < 0.01) were independent predictors for MACE. Although RAS blockers declined rehospitalization to 6 months, β-blocker decreased the rehospitalization rate after 1 month use and the benefit persisted till 12 months. Furthermore, digitalis only lowered rehospitalization to 14 days. CONCLUSION:This study suggests that the use of evidence-based medicine is associated with lower MACE for patients with HF, and these drugs could play vital roles in different periods to decrease the rehospitalization in the clinical setting.
