Abstract P571: Investigating Factors Relevant to Understanding the Hispanic Health Paradox in Patients After Cardiac Arrest

Abstract

Introduction: The growing Hispanic community faces disproportionate hardship due to lower financial capital and educational opportunity. The Hispanic health paradox refers to the finding that Hispanics tend to have better cardiovascular outcomes than non-Hispanics, despite facing greater hardships and more cardiovascular risk factors. Behavioral (e.g., sleep) and psychological (e.g., optimism) factors predict recovery after acute coronary syndrome events, but less is known about how these factors differ by ethnicity after cardiac arrest (CA). We tested demographic, psychological, behavioral, and recovery factors that may underlie the Hispanic health paradox among CA survivors. Hypothesis: We hypothesized that Hispanic vs. non-Hispanic cardiac arrest survivors would have lower income and education but would not differ in behavioral, psychological, and recovery factors. Methods: An observational cohort study, Psychological predictors of recovery after an Acute Cardiac Event (PACE) , enrolled 68 neurologically intact CA survivors admitted to NewYork-Presbyterian Hospital. At hospital discharge, self-reported demographic, psychological, behavioral, and recovery variables were assessed. Independent-samples t-tests of Hispanic vs. non-Hispanic CA survivors were conducted comparing income, education, posttraumatic stress symptoms, depression, negative affect, cardiac anxiety, optimism, positive affect, social support, sleep, physical activity, independent activities of daily living, and self-maintenance. Results: As hypothesized, Hispanic vs. non-Hispanic participants had lower income, Mann Whitney U = 99.00, z = -3.46, p < .01, and lower education, Mann Whitney U = 336.00, z = -2.65, p = .01. Unexpectedly, Hispanic patients reported greater cardiac anxiety M = 39.60, SD = 16.70) than non-Hispanic patients ( M = 30.29, SD = 11.67), t (66) = -2.722, p = .008. No other tested factors were significant, all p s ≥ .419. Conclusions: Cardiac anxiety is the only tested variable that differed by ethnicity. While Hispanic ethnicity may be protective for certain aspects of cardiovascular health, the present findings indicate that Hispanic CA survivors experience higher psychological distress, which itself is a known risk factor for poor health behaviors. Future research should assess potential drivers of cardiac anxiety (e.g., mistrust of healthcare system, poor patient-physician communication). Future intervention research should target heart-related fear during CA recovery.
