1092-P: Lipoprotein Insulin Resistance Index and Mortality in Heart Failure: A Population Study

Heart failure (HF) is associated with metabolic alterations, including insulin resistance (IR) . Perturbations in lipid metabolism and insulin signaling may impact outcomes, but the relationship between IR and mortality is not well characterized. The Lipoprotein Insulin Resistance Index (LPIR) is a score (0-100; higher values signify greater IR) calculated from 6 lipoprotein subclass/size parameters measured by nuclear magnetic resonance (NMR) . We examined the association between LPIR and death in a HF community cohort. LPIR was measured by NMR LipoProfile®. Meta-Analysis Global Group in Chronic HF (MAGGIC) scores were calculated from clinical data. Kaplan-Meier curves were used to evaluate survival; Cox regression was used to estimate risk of death by LPIR quartile. Among 1,381 community-dwelling persons with HF, the median LPIR score was 38 (IQR 21-56) . Higher LPIR was associated with younger age, diabetes, smoking, obesity, and lower MAGGIC scores, but not ejection fraction. Survival increased by LPIR quartile (p
