Characteristics of Discharged Elderly Patients with Acute Heart Failure Followed by Board-Certified-Cardiologists in a Rural Area of Japan.

The worldwide incidence rates of heart failure (HF) are approaching pandemic status due to aging societies. Board-certified cardiologists (BCCs) of the Japanese Circulation Society (JCS) are cardiologists who have completed the respective fellowship program and passed the examination. However, in rural areas, patients have limited access to medical care for social or geographical reasons. The clinical features of the specialist's follow-up for HF patients in rural areas are unclear.This study consists of 205 consecutive discharged elderly patients who were admitted to our hospital due to acute HF (AHF). All patients were recommended for follow-up with BCCs-JCS by the multidisciplinary HF team at the discharge-care planning meeting. The aim of this study was to investigate the clinical features and impact of BCC follow-up for discharged elderly patients with AHF in rural areas.A total of 156 patients chose follow-up with BCCs-JCS (BCC group), and 49 patients chose follow-up with non-BCCs-JCS (non-BCC group). Patients in the BCC group were younger (83 [76-86] versus 89 [75-93] years old, P < 0.001) and had more frequent use of β-blockers (67% versus 39%, P < 0.001). The degree of frailty assessed by the clinical frailty scale was more severe in the non-BCC group than in the BCC group (4 [3-5] versus 6 [4-7], P < 0.001). The non-BCC group lived in nursing homes more frequently than the BCC group (16% versus 5%, P = 0.011).The HF patients followed by BCCS-JCS in rural areas were younger and had less frailty.
