    Abstract:
    Differences in geometric adaptation of the left ventricle and associated cardiovascular risk may reflect the differential effects of classic risk factors and arterial stiffness on the left ventricle. In the present study, the influence of cardiovascular risk factors and arterial stiffness indexes on left ventricular (LV) geometry types were studied in a large community-based cohort of young adults. As part of the Bogalusa Heart Study, echocardiographic examinations of the heart were performed on 786 black and white adults (age range 24 to 43 years, average 36; 42% men, 70% white). Arterial stiffness indexes of the study cohort included aorta-femoral pulse wave velocity, carotid artery elastic modulus, and arterial compliance using tonometry. Pulse pressure in young adults with concentric LV hypertrophy (47 +/- 11 mm Hg) was significantly higher than in those with eccentric LV hypertrophy (40 +/- 8 mm Hg) and normal geometry (37 +/- 7 mm Hg). Multinomial logistic regression analysis showed that widened pulse pressure, the presence of diabetes mellitus, and increased body mass index were associated with concentric LV hypertrophy compared with normal geometry. Similarly, higher Peterson's and Young's elastic modulus of the carotid arteries and lower large- and small-artery compliance, in addition to increased body mass index, diabetes mellitus, and black race, were associated with concentric LV hypertrophy in young adults. In conclusion these data suggested that concentric LV hypertrophy was associated with widened pulse pressure, increased arterial stiffness, and decreased arterial compliance in young adults.
