RESUMO

Background Risk assessment is the cornerstone for atherosclerotic cardiovascular disease ( ASCVD ) treatment decisions. The Pooled Cohort Equations ( PCE ) have not been validated in disaggregated Asian or Hispanic populations, who have heterogeneous cardiovascular risk and outcomes. Methods and Results We used electronic health record data from adults aged 40 to 79 years from a community-based, outpatient healthcare system in northern California between January 1, 2006 and December 31, 2015, without ASCVD and not on statins. We examined the calibration and discrimination of the PCE and recalibrated the equations for disaggregated race/ethnic subgroups. The cohort included 231 622 adults with a mean age of 53.1 (SD 9.7) years and 54.3% women. There were 56 130 Asian (Chinese, Asian Indian, Filipino, Japanese, Vietnamese, and other Asian) and 19 760 Hispanic (Mexican, Puerto Rican, and other Hispanic) patients. There were 2703 events (332 and 189 in Asian and Hispanic patients, respectively) during an average of 3.9 (SD 1.5) years of follow-up. The PCE overestimated risk for NHW s, African Americans, Asians, and Hispanics by 20% to 60%. The extent of overestimation of ASCVD risk varied by disaggregated racial/ethnic subgroups, with a predicted-to-observed ratio of ASCVD events ranging from 1.1 for Puerto Rican patients to 1.9 for Chinese patients. The PCE had adequate discrimination, although it varied significantly by race/ethnic subgroups (C-indices 0.66-0.83). Recalibration of the PCE did not significantly improve its performance. Conclusions Using electronic health record data from a large, real-world population, we found that the PCE generally overestimated ASCVD risk, with marked heterogeneity by disaggregated Asian and Hispanic subgroups.

RESUMO

BACKGROUND: Hispanics are the largest minority population in the United States (18%). They represent a heterogeneous and growing population. Cancer is the leading cause of death among Hispanics, yet few studies have described cancer mortality burden by specific Hispanic group nationwide. METHODS: Cancer-related deaths from U.S. death certificates for the years 2003-2012 were analyzed for decedents identifying as Mexican, Puerto Rican, Cuban, and Central or South American. We calculated descriptive statistics, including potential years of lives lost (PYLL), age-adjusted rates, standardized mortality ratios, and fitted JoinPoint regression models, to evaluate annual trends by Hispanic group, using non-Hispanic Whites (NHW) as the reference population. RESULTS: We identified 287,218 cancer-related deaths among Hispanics and 4,570,559 among NHWs. Mortality trends were heterogeneous across Hispanic groups. Female NHWs and male Puerto Ricans had the greatest rates of adjusted PYLL per 1,000 (NHWs, 19.6; Puerto Ricans, 16.5). Liver cancer was ranked among the top 5 cancer-related deaths for every Hispanic group, but not for NHWs. Stomach cancer mortality was twice as high for most Hispanic groups when compared with NHWs and especially high for Mexicans [male standardized mortality ratio (SMR), 2.07; 95% confidence interval (CI), 2.01-2.13; female SMR, 2.62; 95% CI, 2.53-2.71]. CONCLUSIONS: We observed marked heterogeneity in cancer mortality across Hispanic groups. Several cancers affect Hispanics disproportionately compared with NHWs. Screening programs in Hispanics should be considered for stomach and liver cancer. IMPACT: Disaggregated analysis of Hispanics is needed to fully understand cancer burden among the diverse Hispanic population and is critical for cancer prevention and control efforts.
