Abstract 14793: Relationship Between Self-Rated Health and Clinical Outcomes in Hypertension: A Secondary Analysis of the Systolic Blood Pressure Intervention Trial (SPRINT)

Abstract

Background: Self-rated health (SRH) is a well-known independent predictor of mortality. However, the association of SRH with clinical outcomes in patients with hypertension remains uncertain. SPRINT investigated the benefit of intensive (vs. standard) blood pressure treatment in patients with high-risk hypertension. Objective: To examine the association between SRH and the primary SPRINT outcome, which was defined as the composite of myocardial infarction, other acute coronary syndromes, stroke, heart failure, and cardiovascular death. Methods: A trained study personnel administered a questionnaire to assess SRH. Each participant rated their overall health as excellent, very good, good, fair, or poor (E, VG, G, F, P). We categorized SRH into excellent, very good, good and fair/poor. Multivariate Cox regression was used to examine the association of SRH and clinical outcomes in SPRINT. Results: We included 9,319 participants (aged 67.9±9 years, 35.6% women, 57.6% White) who had available data on SRH. After a median follow-up of 3.8 years, 724 and 500 primary outcome and all-cause mortality events occurred, respectively. Relative to SRH of excellent, the risk of the primary outcome (HR 95% CI) associated with very good, good, and poor/fair SRH was 1.11 (0.78-1.56; p=0.555), 1.45 (1.03-2.05; p=0.036) and 1.87 (1.28-2.75; p=0.001), respectively. Similarly, relative to excellent, the risk of all-cause mortality (HR 95% CI) associated with very good, good, and poor/fair SRH was 1.13 (0.73-1.76; p=0.581), 1.72 (1.12-2.64; p=0.014) and 2.11 (1.32-3.38; p=0.002), respectively. Poorer SRH was also associated with a higher risk of each component of the primary outcome and adverse events ( Table). Conclusion: In the SPRINT cohort, SRH was independently associated with the risk of cardiovascular outcomes, mortality, and adverse events. Further studies are needed to explore the utility of incorporating SRH in the assessment of risk in patients with hypertension.
