Abstract
OBJECTIVES: The objective of this study was to determine the impact of nonfatal cardiovascular (CV) events on changes in health-related quality of life (HRQL). BACKGROUND: There is limited understanding of the impact of nonfatal CV events on long-term changes in HRQL in survivors of myocardial infarction (MI). METHODS: The VALIANT (Valsartan In Acute Myocardial Infarction) trial enrolled 14,703 patients post-MI complicated by Killip class II or higher (scale measuring heart failure severity post-MI ranging from class I to IV) and/or reduced ejection fraction. The HRQL substudy included 2,556 (17.4%) patients who completed the EQ-5D with 5 questions, with responses mapped to utility weight on a scale of 0 to 1 and a visual analog scale (VAS) ranging from 0 (worst) to 100 (best) imaginable health state. EQ-5D was administered at baseline and 6, 12, 20, and 24 months. The trajectory of EQ-5D scores was developed by using linear mixed effects regression models with calculation of deviation from this trajectory after nonfatal CV events. Patients who died before the next EQ-5D assessment were excluded. RESULTS: Over a 2-year period, 597 patients experienced a nonfatal CV event and survived to have another EQ-5D assessment. Their baseline EQ-5D scores were lower than patients without a subsequent nonfatal CV event (VAS 61.0 ± 19 vs 68.2 ± 18 [p < 0.001] and US-based utility score 0.76 ± 0.22 vs 0.83 ± 0.17 [p < 0.001]). These patients with CV events experienced a trajectory-adjusted 6.6 point decrease (p < 0.001) in VAS scores and a 0.07 decrease (p < 0.001) in utility score after the nonfatal CV event. CONCLUSIONS: MI survivors suffering a CV event experienced significantly worse HRQL than their previous trajectory, suggesting that generic instruments can be responsive to nonfatal events. Reduction in nonfatal CV events may affect longitudinal changes in HRQL.
