Abstract 16708: Valvular Disease in Hispanics
Introduction: Hispanics represent the largest racial/ethnic minority group in the United States. There are studies characterizing valvular heart disease in Caucasians and African Americans, but not among Hispanics.
Methods: As part of Echocardiographic Study of Latinos (ECHO-SOL) 1,818 participants ≥45 years of age underwent a comprehensive echocardiographic exam. We assessed prevalence of mitral (MR), tricuspid (TR), pulmonic (PR) and aortic (AR) regurgitation as well as bicuspid aortic valve (BAV), mitral valve prolapse (MVP), mitral (MS) and aortic (AS) stenosis. Logistic regression analysis using survey statistics and sampling weights was employed to examine the associations of clinical and sociodemographic variables with valvular lesions.
Results: Study population mean age 55.2 (SE 0.17); 57.4% were female. The prevalence of each valvular lesion is described in the Table. The overall prevalence of AVHD was 3.1% with no significant difference across gender; however, the prevalence of valvular lesions was greater with increasing age. The proportion of US vs. foreign born individuals was similar among those with vs. without AVHD (p=0.31). However, the weighted prevalence of AVHD was highest among Central Americans (8.4%) and lowest among Mexicans (1.2%). Regurgitant lesions of moderate or greater severity were present in 2.4% of the target population and stenotic lesions of moderate or greater severity in 0.2%. Compared to those without, those with AVHD were more likely to have health insurance coverage (59.6% vs 79.2%, p=0.007), but similar income (p=0.06) and educational status (p=0.46). Regurgitant lesions were associated with lower BMI, whereas stenotic lesions were associated with increasing BMI.
Conclusions: Our data provide the first population-based estimates of the prevalence of valvular disease in Hispanic. Valvular disease is fairly common in the Hispanicpopulation and may constitute an important public health problem.
