Prognostic Value of Insulin Resistance Assessed by HOMA-IR in Non-Diabetic Patients with Decompensated Heart Failure.

The predictive value of insulin resistance in patients hospitalized with heart failure is unknown. To evaluate prognostic value of insulin resistance (defined by a HOMA IR ≥ 2.5) for the combined event of death and readmission at 90 and 365 days post discharge and to determine if there are differences according to ejection fraction. Prospective study of 156 p hospitalized for acute heart failure without diabetes. A total of 83 years, 48% female, EF ≤ 45% 48%. Of 28% presented HOMA ≥2.5. HOMA IR ≥2.5 was associated with combined event (OR 2.4; 95% CI 1.9-5.1; P: 0.02) at 90 days. A multivariate analysis demonstrated its independent predictive value (OR 2.5, 95% CI 1.1-5.8; P: 0.03). At 1 year follow-up HOMA IR did not predict events. The predictive value of HOMA-IR was not associated with ventricular function. HOMA IR index was a predictor of a combined event at 90 days in our population. It is a simple determination that could contribute to identify higher risk patients during this vulnerable post-discharge phase. These data must be validated in larger studies.
