Abstract P352: Racial/Ethnic Differences in Cardiovascular Disease Outcomes among Patients with Hypertension or Type 2 Diabetes

Background: This study assesses racial/ethnic differences in CVD outcomes among patients with hypertension (HTN) or type 2 diabetes (T2DM) across Asian American subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese), Mexican, non-Hispanic black (NHB), and non-Hispanic White (NHW) in a large, mixed payer ambulatory care setting in northern California. Study Design: We estimated the rate of CVD incidence among adult patients with HTN (N=171,864) or T2DM (N=10,570), or both (N=36,589) using electronic health records between 2000-2013. Average follow-up was 4.5 years. CVD, including CHD (410-414), PVD (415, 440.2, 440.3, 443.9, 451, 453), and stroke (430-434), was defined by ICD-9 codes; HTN and T2DM were defined by ICD-9 codes, medication history, or two or more elevated blood pressure measures/abnormal glucose lab test results. Cox proportional hazard models were used to estimate hazard ratios for CHD, PVD, and stroke across race/ethnicity. Results: Among these patients, 10.5% developed C...
