Key result
J-MACS Risk Score aligns with HM3RS to stratify 3-year mortality in advanced HF.
Why the study?
Do the J-MACS, HeartMate3, and J-HeartMate risk scores predict 3-year mortality in Japanese patients with heart failure?
Observational

The J-MACS, HeartMate3, and J-HeartMate risk scores are useful for predicting 3-year mortality in Japanese heart failure patients, extending their utility beyond just post-LVAD prognosis.
BACKGROUND: In addition to the J-HeartMate Risk Score (J-HMRS) and HeartMate 3 Risk Score (HM3RS), the J-MACS Risk Score (J-MACS-RS) was developed to predict death after left ventricular assist device (LVAD) implantation in Japanese patients with heart failure (HF). However, the correlation between these scores, the characteristics of high-risk patients as per these scores, and the mortality stratification of these scores in HF patients regardless of LVAD implantation are still not fully understood. METHODS AND All scores stratified the 3-year mortality in patients with HF. CONCLUSIONS: The J-MACS-RS correlated well with the J-HMRS and HM3RS. These scores may predict 3-year mortality, even in Japanese HF patients, regardless of LVAD implantation.

Aoki et al. (2025) conducted an observational in Heart failure. J-MACS, HeartMate3, and J-HeartMate Risk Scores was evaluated on 3-year mortality. The J-MACS Risk Score correlated well with the J-HeartMate and HeartMate 3 Risk Scores, and all scores stratified 3-year mortality in Japanese patients with heart failure.
