Background-The American Heart Association introduced the Life's Simple 7 (LS7) metrics to assess and promote cardiovascular health. We sought to examine the association between the LS7 metrics and incident heart failure (HF) in a multiethnic cohort. Methods and Results-We analyzed data from 6506 participants of the Multi-Ethnic Study of Atherosclerosis free of cardiovascular disease at baseline. The LS7 metrics (smoking, physical activity, body mass index, diet, blood pressure, total cholesterol, and blood glucose) were graded on a scale of 0 to 2, with 2 indicating ideal status, 1 intermediate status, and 0 poor status. Points were summed, thus the LS7 score ranged from 0 to 14. Cox proportional hazard ratios and incidence rates of HF per 1000 person-years were calculated. During a median follow-up of 12.2 years, 262 (4%) participants developed HF. Incidence of HF decreased as the number of ideal LS7 metrics increased; 5.9 per 1000 person-years for participants with 0 to 1 ideal metrics and 0.6 per 1000 person-years for those with 6 to 7 ideal metrics. Compared with inadequate scores (0-8 points), hazard ratios for HF were 0.57 (0.43-0.76) and 0.31 (0.19-0.49) for average (9-10 points) and optimal (11-14 points) scores, respectively. A similar pattern was observed when the results were stratified by 4 racial/ethnic groups: white, Chinese American, black, and Hispanic. Conclusions-A lower risk of HF with more favorable LS7 status regardless of race/ethnicity suggests that efforts to achieve ideal cardiovascular health may reduce the burden of HF, a major source of morbidity and mortality.
