Implication
May aid risk stratification in ambulatory chronic HF; leaves open need for prospective validation before adoption.
Key Points
- To develop and validate risk prediction models for mortality outcomes in ambulatory patients with chronic heart failure.
- Prospective cohort study of 992 consecutive ambulatory chronic heart failure patients followed for a median of 44 months.
- Multivariable Cox regression models evaluated independent predictors of all-cause mortality, cardiac mortality (primary endpoint), pump-failure death, and sudden death.
- Over the follow-up period, there were 267 all-cause deaths, 213 cardiac deaths (primary endpoint), 123 pump-failure deaths, and 90 sudden deaths.
- Ten independent predictors—including prior vascular events, left atrial size, ejection fraction ≤35%, arrhythmias, eGFR <60 mL/min/1.73 m², hyponatremia, elevated NT-proBNP, and positive troponin—were combined into the MUSIC Risk score.
- A cardiac mortality score greater than 20 points identified a high-risk patient subgroup with a four-fold increase in cardiac mortality risk.
