Abstract
BACKGROUND: Cardiovascular disease (CVD) imposes a major healthcare burden on young descendants of South Asian migrants living in the western world. In comparison to the native population, the prevalence is significantly higher and the prevalence of CVD risk factors is increasing rapidly. The cardiovascular risk profile and 10-year risk scores of South Asian descendants were evaluated in two cohorts with a 10-year time difference. METHODS: Two cross-sectional studies, conducted in 2004 and 2014, focused on asymptomatic South Asian descendants aged 18-59 years were performed. A short questionnaire, BMI, waist circumference, blood pressure, and nonfasting blood tests were obtained. The cohort of 2014 was matched with the cohort of 2004, based on age, gender, and family history of CVD. RESULTS: In 2014, 674 South Asians (44% men, age 38.2 ± 12.0 years) were matched with 674 South Asians (44% men, age 38.3 ± 12.1 years) included in 2004. Notably, hypertension prevalence decreased significantly in 2014 (10.6% vs 23.1% in 2004, P < 0.001), while mean BMI increased (26.1 vs 24.9, P < 0.001). The mean Framingham risk score was lower in 2014 (5.31 ± 6.19%) than in 2004 (6.45 ± 8.02%, P < 0.05). CONCLUSION: This study demonstrates that South Asian descendants in 2014 have a lower but still high absolute risk for coronary events compared to 2004. Important differences in cardiovascular risk profile exist. Despite improvements, South Asian descendants in 2014 still face a high absolute risk for coronary events compared to 2004, indicating the necessity for continued primary prevention and lifestyle interventions.
