OBJECTIVES: This study sought to evaluate INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) profiles for prognostic use among ambulatory non-inotrope-dependent patients with heart failure with reduced ejection fraction (HFrEF).
BACKGROUND: Data for INTERMACS profiles and prognoses in ambulatory patients with HFrEF are limited.
METHODS: We evaluated 3-year outcomes in 969 non-inotrope-dependent outpatients with HFrEF (EF: ≤40%) not previously receiving advanced HF therapies. Patients meeting an INTERMACS profile at baseline were classified as profile 7 (n = 348 [34.7%]); 146 patients (14.5%) were classified profile 6; and 52 patients (5.2%) were classified profile 4 to 5. Remaining patients were classified "stable Stage C" (n = 423 [42.1%]).
RESULTS: Three-year mortality rate was 10.0% among stable Stage C patients compared with 21.8% among INTERMACS profile 7 (hazard ratio [HR] vs. Stage C: 2.45; 95% confidence interval [CI]: 1.64 to 3.66), 26.0% among profile 6 (HR: 3.93; 95% CI: 1.64 to 3.66), and 43.8% among profile 4 to 5 (HR: 6.35; 95% CI: 3.51 to 11.5) patients. Hospitalization rates for HF were 4-fold higher among INTERMACS profile 7 (38 per 100 patient-years; rate ratio [RR] vs. Stage C: 3.88; 95% CI: 2.70 to 5.35), 6-fold higher among profile 6 patients (54 per 100 patient-years; RR: 5.69; 95% CI: 3.72 to 8.71), and 10-fold higher among profile 4 to 5 patients (69 per 100 patient-years; RR: 9.96; 95% CI: 5.15 to 19.3) than stable Stage C patients (11 per 100 patient-years). All-cause hospitalization rates had similar trends. INTERMACS profiles offered better prognostic separation than NYHA functional classifications.
CONCLUSIONS: INTERMACS profiles strongly predict subsequent mortality and hospitalization burden in non-inotrope-dependent outpatients with HFrEF. These simple profiles could therefore facilitate and promote advanced HF awareness among clinicians and planning for advanced HF therapies.
