Abstract

Despite beneficial effects on morbidity and mortality after acute myocardial infarction (AMI), concerns remain about the safety of statin therapy, particularly their potential effects on cognitive and physical function, in elderly individuals. Among statin-naive AMI patients age ≥65years in a multicenter US registry, we examined the association between statin prescription at discharge and change in cognition (via Modified Telephone Interview for Cognitive Status [TICS-M]) assessed at 1 and 6 months after AMI. Short Form-12 Physical Component score, hand grip, walk time, and chair-rise tests were used to assess physical function. We conducted noninferiority testing to evaluate the hypothesis that the mean change in cognitive function was no worse among patients recently started on statins compared with those who were not. Among 317 elderly AMI patients, 262 patients (83%) were prescribed a statin at discharge and 55 were not. After matching for propensity to be discharged on statin after AMI, the effect of statin treatment on change in TICS-M from 1 to 6 months (estimated difference, 0.11 points; 95% confidence interval: -2.11 to 2.32, P = 0.92) showed noninferiority (inferiority threshold 3 points). There were no significant differences in any physical function measure. Among statin-naive elderly individuals recovering from AMI, initiation of statin therapy was not associated with detectable changes in short-term cognitive or physical function. These findings support the general safety of statin therapy for secondary prevention in this population.
