Clinical outcomes of patients from older community hospitalized for heart failure in guideline-directed medical therapy era: Insights from the COMPASS-HF registry.

Abstract

Background: Despite strong recommendations in the latest guidelines for implementing guideline-directed medical therapy (GDMT) before discharge, there is a lack of data on the clinical characteristics and outcomes of older patients with heart failure (HF). Therefore, this study aimed to investigate the clinical characteristics and outcomes of patients with HF in a super-aging society during the GDMT era.

Methods and results: In the COMPASS-HF study including 305 consecutive hospitalized patients, 177 with acute HF were identified through a medical record review. The mean age of the enrolled patients was 86.2 years, and 46.3 % were men. The mean simple GDMT score, which is recognized as a useful prognostic tool for Japanese patients with HF, was 5.0. The incidences of all-cause death and HF hospitalization were 46.5 % and 19.4 %, respectively. The incidences of all-cause death and cardiovascular death were significantly lower in the high simple GDMT score group (≥5 points) than in the low simple GDMT score group (≤4 points) (p = 0.049 and p = 0.044, respectively). However, no significant differences were noted in HF hospitalization and composite events (cardiovascular death and HF hospitalization) between the groups (p = 0.564 and p = 0.086, respectively).

Conclusions: While GDMT was well-implemented in the older community, the mortality rate among hospitalized patients with HF remained high. Although GDMT appears to have reduced the HF hospitalization rate, further validation and development of an optimal predictive model for elderly patients with HF are essential.

X (formerly twitter): In the older community, although the short- and long-term mortality of hospitalized patients with HF is still high even in the GDMT era, the HF hospitalization rate is suppressed, probably due to GDMT. A simple GDMT score may also be useful for stratifying the prognosis of older patients with HF. #HeartFailure#Mortality#GDMT#Fantastic4.
