Background There is a high burden of premature cardiovascular disease (CVD) among African Americans. Measures of central aortic blood pressure (CASP) and wave reflection are predictive of CVD risk in adults, but there is a paucity of data regarding the relation of these measures to target organ damage among adolescents. The objective of this study was to examine the relationship between CASP, central pulse pressure (CPP), and augmentation index (AI) with left ventricular mass index (LVMI).MethodsA cohort of 120 African-American adolescents was examined. Study participants underwent measurement of peripheral blood pressure (BP) using auscultation, pulse wave analysis (PWA) for determination of CASP, CPP, and AI, and echocardiography for determination of LVMI. Results The cohort was 55% male, with mean BP 114/62 mm Hg, mean LVMI 36 g/m 2.7, mean CASP 94 mm Hg, mean CPP 31 mmHg, and mean AI was 0.5%. After adjustment for potential confounders, peripheral systolic BP (SBP) was significantly associated with LVMI (P = 0.008), but diastolic pressure was not (P = 0.887). The CASP and CPP were significantly associated with LVMI (P = 0.020 and 0.005, respectively). Peripheral SBP, CASP, and CPP had similar associations with respect to LVMI (r 2 0.26, 0. 26, and 0.27, respectively). Conclusion Central BP is associated with LVMI among African-American adolescents, and these associations are similar to those seen with peripheral BP measurements.
