Abstract

BACKGROUND: Data are limited regarding the relationship between the life-course burden of risk factors and adult cardiac function. This study sought to examine the impact of long-term burden of body mass index (BMI) and blood pressure (BP) levels on changes in adult left ventricular (LV) structure and function in a community-based cohort. METHODS AND RESULTS: The longitudinal study cohort consisted of 1108 adult patients (726 White; 41.9% men; mean age, 48.2 years in the last survey) who had been examined 4 to 16 times for BMI and BP and echocardiographic LV structure and function in adulthood, with a mean follow-up period of 38.8 years. The area under the curve was used as a measure of long-term burden of BMI and BP. Adult LV mass index was significantly associated with childhood and adulthood BMI and systolic BP (SBP), and their area under the curve values (β=0.07–0.37; P<0.05 for all). Adult LV ejection fraction was negatively associated with childhood BMI (β=−0.08), adult BMI (β=−0.07) and BMI area under the curve (β=−0.07) (P<0.05 for all); the effects of SBP measures were not significant. Adult E/A ratio was negatively associated with adulthood SBP (β=−0.13; P<0.01) and total area under the curve of SBP (β=−0.13; P<0.01). E/e′ ratio was positively associated with BMI and SBP measures. The effects of diastolic BP measures were substantially similar to those of SBP measures. Participants with LV hypertrophy, eccentric hypertrophy, and concentric hypertrophy had significantly lower LV ejection fraction and higher E/e′ ratio. CONCLUSIONS: These observations provide strong evidence that early-life adiposity and BP levels and their life-course cumulative burdens are associated with subclinical changes in adult LV structure and function in the general population.
