Abstract: The American Heart Association AHA recently developed the Cardiovascular Health Index CVHI, a health metric consisting of 7 modifiable risk factors. The relationship of the CVHI with preclinical markers, such as carotid intima-media thickness CIMT has not been assessed. We examined 490 male monozygotic and dizygotic twins without overt cardiovascular disease. CIMT was measured using B-mode ultrasonography. Each of the 7 CVHI components blood pressure, fasting glucose, total cholesterol, body mass index, physical activity, healthy diet, and smoking was given a point score of 0, 1, or 2 to represent poor, intermediate, or ideal health, respectively. A CVHI summation score was computed range 0 to 14 and categorized as inadequate 0 to 4, average 5 to 9, or optimum 10 to 14 cardiovascular health. Mixed-model regression was used to examine the association of the CVHI with CIMT. The mean age of the twins was 55.4 years, and 61% were monozygotic. The mean CIMT was 0.75 ± 0.11 mm and the mean CVHI score was 7.7 ± 2.1. There was an inverse correlation between CVHI and CIMT Spearman r=-0.22, P<0.01. For every 5-unit increase in overall CVHI score indicating better cardiovascular health category, CIMT decreased by 0.045 mm P<0.001 after adjusting for demographic variables and other confounders. Within monozygotic twin pairs, a 5-unit increment in CVHI score was associated with a 0.05 mm lower CIMT P<0.001. The CVHI is independently associated with CIMT and the association is not confounded by shared genetic and other familial factors.
