Keywords: aging; aspirin; body weight EN aging aspirin body weight 1110 1112 3 04/20/20 20200331 NES 200331 A recent meta-analysis[1] of individual patient data from several randomized, controlled trials evaluating aspirin for the prevention of primary or secondary cardiovascular events found that the protective effect of low-dose aspirin (<=100 mg) was limited to individuals weighing <70 kg, driven by lean body mass (LBM) but not body mass index (BMI).[1] Given the limited number of people >=70 years of age who were included in the meta-analysis[1] and calls for validation of these findings,[2],[3] we investigated whether body habitus modulated the efficacy of aspirin in a post hoc analysis of the ASPREE trial (Aspirin in Reducing Events in the Elderly).[4] ASPREE randomized 19 114 older participants to daily 100-mg enteric-coated aspirin (9525) or matched placebo (9589) and followed them up for a median of 4.7 years for disability-free survival and other clinical outcomes.[4] Trial participants were community-dwelling Australian (16 703) and US (2411) men and women who were >=70 years of age at enrollment or >=65 years of age for US blacks and Hispanics. At baseline, anthropometric indexes (mean±SD) of body weight, BMI, waist circumference, and LBM in the aspirin versus placebo groups were 77.0±15.1 kg versus 77.0±14.8 kg, 28.1±4.8 kg/m SP 2 sp versus 28.1±4.7 kg/m SP 2 sp , 97±13 cm versus 97±13 cm, and 49.8±8.3 kg versus 49.9±8.2 kg, respectively. Larger BMI or waist circumference or LBM also did not alter the effect of aspirin on the risk of cardiovascular disease or major hemorrhage (Figure). [Extracted from the article]
