Health-related quality of life in patients with acute coronary syndromes and treated with ticagrelor or clopidogrel
De Franco AC, Oldridge N. Health-related quality of life in patients with acute coronary syndromes and treated with ticagrelor or clopidogrel. Expert Rev Pharmacoecon Outcomes Res. 2014 Feb;14(1):23-6.
Evaluation of: Levin LA, Wallentin L, Bernfort L et al. Health-related quality of life of ticagrelor versus clopidogrel in patients with acute coronary syndromes results from the PLATO trial. Value Health 16(4), 574-580 (2013). Antiplatelet therapy is considered essential treatment for acute coronary syndromes with or without ST-segment elevation and after stent procedures. The PLATelet inhibition and patient Outcomes (PLATO) trial compared ticagrelor or clopidogrel for the prevention of cardiovascular events. Prespecified substudies included a health-related quality of life (HRQL) study; the EQ-5D, a self-report, standardized, nondisease-specific utility measure with a single index value for health status, was used to assess HRQL. In the primary HRQL analysis, the mean 12-month HRQL score in 15,212 patients was reported to be 0.840 in the ticagrelor group and 0.832 in the clopidogrel group (p = 0.046). Excluding patients who died resulted in no difference in HRQL between patients treated with ticagrelor or clopidogrel (0.864 and 0.863, respectively; p = 0.69). The improved survival and reduction in cardiovascular events with ticagrelor as demonstrated in the main PLATelet inhibition and patient Outcomes trial are apparently obtained with no difference in quality of life.
