  • Beschreibung: ObjectivesTo determine the prognostic value of slow gait in predicting outcomes 1 year after acute myocardial infarction (AMI).DesignObservational cohort with longitudinal follow‐up.SettingTwenty‐four U.S. hospitals participating in the Translational Research Investigating Underlying disparities in recovery from acute Myocardial infarction: Patients' Health status Registry.ParticipantsOlder adults (≥65) with in‐home gait assessment 1 month after AMI (N = 338).MeasurementsBaseline characteristics and 1‐year mortality or hospital readmission adjusted using Cox proportional hazards regression in older adults with slow (<0.8 m/s) versus preserved (≥0.8 m/s) gait speed.ResultsSlow gait was present in 181 participants (53.6%). Those with slow gait were older, more likely to be female and nonwhite, and had a higher prevalence of heart failure and diabetes mellitus. They were also more likely to die or be readmitted to the hospital within 1 year than those with preserved gait (35.4% vs 18.5%, log‐rank P = .006). This association remained significant after adjusting for age, sex, and race (slow vs preserved gait hazard ratio (HR) = 1.76, 95% confidence interval (CI)=1.08–2.87, P = .02) but was no longer significant after adding clinical factors (HR = 1.23, 95% CI=0.74–2.04, P = .43).ConclusionSlow gait, a marker of frailty, is common 1 month after AMI in older adults and is associated with nearly twice the risk of dying or hospital readmission at 1 year. Understanding its prognostic importance independent of comorbidities and whether routine testing of gait speed can improve care requires further investigation.
