Abstract

Objective: The aim of this study was to explore race-ethnic differences in the association between plasma lipid components and risk of incident myocardial infarction (MI). Design/methods: As part of the Northern Manhattan Study, 2,738 community residents without cardiovascular disease were prospectively evaluated. Baseline fasting blood samples were collected, and lipid panel components were analyzed as continuous and categorical variables. Cox proportional hazards models were used to calculate HRs and 95% CIs for incident MI after adjusting for demographic and cardiovascular risk factors. Results: The mean age was 68.8 ± 10.4 years; 36.7% were men. Of the participants, 19.9% were non-Hispanic white; 24.9%, non-Hispanic black; and 52.8%, Hispanic (>80% from the Caribbean). Hispanics had lower mean high-density lipoprotein cholesterol (HDL-C) and higher triglycerides (TG)/HDL-C. During a mean 8.9 years of follow-up, there were 163 incident MIs. In the whole cohort, all lipid profile components were associated with risk of MI in the expected directions. However, HDL-C (adjusted HR per 10 mg/dL increase 0.93, 95% CI 0.76-1.12) and TG/HDL-C >2 (adjusted HR 0.89, 95% CI 0.51-1.55) were not predictive of MI among Hispanics but were predictive among non-Hispanic blacks and whites. Triglycerides/HDL-C per unit increase was associated with an 8% higher risk of MI among Hispanics (adjusted HR 1.08, 95% CI 1.04-1.12). Conclusions: In Hispanics, low HDL-C and TG/HDL-C >2 were not associated with MI risk. Our data suggest that a different TG/HDL ratio cutoff may be needed among Hispanics to predict MI risk.
