Hospitalized adults with acute MI and anemia (hemoglobin [Hb] less than 10 g\/dL). The MINT trial randomized 3504 patients, and this analysis included those who had QOL data collected and those who died before the 30-day follow-up period.

A total of 2525 (88.8%; 1254 [49.7%] in the restrictive group and 1271 [50.3%] in the liberal group) had QOL data, and 319 (11.2%) died before 30-day follow-up. Overall, there were no differences in mean or median scores for any EQ-5D-5L QOL outcome between assigned transfusion strategies at 30 days postrandomization. Although a higher percentage of patients in the liberal compared with the restrictive transfusion group reported no problems compared with any problem in usual activities (506 of 1268 [39.9%] vs 473 of 1247 [37.9%]), mobility (474 of 1270 [37.3%] vs 460 of 1254 [36.7%]), and self-care (858 of 1271 [67.5%] vs 803 of 1254 [64.0%]) domains, none of these differences were statistically significant. Adjusted mixed-effects linear regressions showed no association between assigned transfusion strategy and mean differences in any QOL outcome. Adjusted regressions in several prespecified subgroups showed an association between a liberal transfusion strategy and better QOL scores in domains related to functional capacity, but the effects were only statistically significant in patients with a history of heart failure  (Health Today rating: \u03b2, 2.06 [95% CI, \u22120.23 to 4.35] vs \u22121.44 [95% CI, \u22123.81 to 0.92]; <jats:italic>P<\/jats:italic>\u2009=\u2009.04).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions and Relevance<\/jats:title><jats:p>This secondary analysis of the MINT trial found that in patients with MI and anemia, a liberal transfusion strategy compared with a restrictive transfusion strategy did not affect QOL outcomes 30 days after randomization. This suggests that higher Hb levels maintained with RBC transfusion may not offer significant benefits to QOL overall in patients with MI and anemia. Additional studies may be useful for further examining and validating transfusion\u2019s effect on QOL in patients with MI and heart failure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Trial
