Abstract 17729: Ideal Cardiovascular Health is Associated With a Lower Prevalence of Adverse Left Ventricular Remodeling Patterns in the Framingham Offspring Study
Introduction: The American Heart Association Heart Healthy score (AHA score or Life’s Simple 7™) is inversely associated with atherosclerotic vascular disease including heart failure (HF), but its relationship to adverse left ventricle (LV) geometric patterns (known precursors of HF) is unknown. LV geometry can be categorized into 4 distinct patterns: normal (normal LV mass [LVM] and relative wall thickness [RWT]), concentric remodeling (normal LVM with increased RWT), eccentric hypertrophy (increased LVM with normal RWT) and concentric hypertrophy (increased LVM and RWT).
Hypothesis: We hypothesized that ideal cardiovascular health is inversely associated with adverse LV geometric patterns.
Methods: We evaluated the cross-sectional relations between the AHA score (range 1-7, based on lifestyle and risk factor profile, 7 being healthiest) and the prevalence of echocardiographic LV geometric patterns in 2392 Framingham Offspring Study participants (mean age 58 years, 56% women). Using generalized logits models, we calculated odds ratios (OR) for each pattern of LV remodeling as compared to the normal pattern (that served as referent) for every unit-increase in AHA score, adjusting for age and sex.
Results: Normal geometry was present in 1283 participants (54%), concentric remodeling in 486 (20%), eccentric hypertrophy in 352 (15%) and concentric hypertrophy in 271 (11%). Each unit- increase in the AHA score was associated with lower odds of concentric remodeling and hypertrophy, Table. We did not observe a significant association between the AHA score and the odds of eccentric hypertrophy.
Conclusions: Our findings support the association between ideal cardiovascular health and a lower prevalence of adverse cardiac remodeling, consistent with the favorable impact of both a healthy lifestyle and optimal risk factor profile on HF risk.
