Are there Different Rates of Acute Stroke Risk Factors in the South Texas Mexican American population? (P7.146)

BACKGROUND: Recent studies have shown that there are significant disparities among ethnicities in the United States (US), especially Mexican Americans. The South Texan Mexican American (STMA) population is a unique community with some of the highest rates of hypertension, diabetes and obesity in the country. There is a paucity of data correlating poor outcomes in this population with their unique risk stratification. OBJECTIVE: To evaluate whether risk factors in the STMA are uniquely high compared to published national data, and if there are unique predictors of poor outcome in this acute ischemic stroke (AIS) population. METHODS: Data was abstracted via chart review for all AIS from June 2010-June 2014 from a Gold Plus Target Stroke Honor Roll primary stroke center. Demographics, risk factors, admission national institute of health stroke scale (NIHSS), and discharge modified Rankin score (mRS) were obtained. The risk factors collected were hypertension, diabetes, chronic renal failure, congestive heart failure (CHF), hyperlipidemia, and atrial fibrillation (AFIB). We compared the prevalence of risk factors to the recently published AHA Science Advisory- Status of Cardiovascular Disease and Stroke in Hispanics/Latinos in the US. RESULTS: A total of 1584 patients [mean-age (±SD) 68.6±13.7 years; 55.6[percnt]men] were discharged with the diagnosis of AIS. The proportion of patients with hypertension (89.9[percnt] vs 30.1[percnt]), diabetes mellitus (57.3[percnt] vs 12.7[percnt]), hyperlipidemia (68.8[percnt] vs 48.1[percnt]), and CHF(13.5[percnt] vs 1.9[percnt]) were significantly higher among STMA AIS patients compared with Hispanics/Latinos in the US. AFIB (p<0.001) and CHF (p<0.001) were the only statistically significant predictors of poor outcome. CONCLUSION: In the South Texas Mexican American AIS population, there is greater then a three-fold higher prevalence of hypertension, diabetes and CHF compared with Hispanics/Latinos in the US. AFIB and CHF are significant predictors of poor outcome in this unique population. Disclosure: Dr. Tekle has nothing to disclose. Dr. Hassan has nothing to disclose.
