| Popis: | Introduction: South Asian ethnicity is associated with increased atherosclerotic cardiovascular disease (ASCVD) risk and has been identified as a “risk enhancer” in the 2018 ACC/AHA Guideline on the Management of Blood Cholesterol. Hypothesis: An increased use of statins has been recommended since implementation of the 2013 ACC/ AHA Pooled Cohort Equation (PCE); however, the impact of statins on ASCVD outcomes in South Asians is not well understood. We aim to identify the accuracy of 10-year ASCVD risk prediction by the PCE, based on statin use, in a South Asian cohort. Methods: This is a retrospective cohort study of members within Kaiser Permanente Northern California without existing ASCVD, age range 30-70, for whom lipid panel, ethnic data, and 10-year follow up were available. ASCVD events were defined as acute myocardial infarction, ischemic stroke, and cardiovascular death. The cohort was stratified by statin use: never, at baseline and follow-up and only during follow-up. Predicted probability of ASCVD, using the PCE were calculated and compared to the observed for each ASCVD risk category: low =20.0%. Results: A total of 1,835 South Asian patients were included. ASCVD risk was underestimated by the PCE across all risk categories and statin groups. The greatest disparity was seen in the low-risk ASCVD risk group; entire cohort: 1.8 vs 4.9%, p Conclusions: In a large, community-based South Asian cohort, the PCE underestimated risk in South Asians, who were taking statins, in the low ASCVD risk category. |
