Background Few studies have assessed treatment effects on health-related quality of life (HRQoL) in patients with acute coronary syndrome (ACS) treated without revascularization. The TRILOGY ACS trial randomized patients with ACS to either prasugrel or clopidogrel therapy plus aspirin. Outcomes showed a complex pattern suggestive of late benefits with respect to repeat clinical events and benefits confined to patients who underwent angiography. Here, we examine the HRQoL correlates of these patterns.
Methods HRQoL was measured at baseline and 3, 12, and 24 months or end of study (EOS) in 7243 patients aged <75 years using the EuroQol 3-level, group 5-dimension index (EQ-5D). Linear mixed effects models for repeated measures were used to examine treatment differences in HRQoL overall, stratified by angiography status, and among patients who did and did not have non-fatal events.
Results No baseline differences in HRQoL were seen between patients randomized to prasugrel (n = 3620) or clopidogrel (n = 3623). At 24 months, remaining patients assigned to prasugrel (n = 1450) vs. clopidogrel (n = 1443) had higher EQ-5D index scores (86.4 vs. 84.9, P =.01). Mixed effects models found no difference in EQ-5D scores among prasugrel and clopidogrel patients overall across subgroups stratified by angiography status. However, among patients with non-fatal clinical events, patients on clopidogrel reported a larger decrement in HRQoL than patients on prasugrel (79.5 +/- 18.1 vs. 80.6 +/- 18.0; P = .02).
Conclusions Overall, there was no difference in HRQoL outcomes among patients receiving prasugrel vs. clopidogrel. However, the differential effects of the treatments among patients with non-fatal events require further investigation.
