- Background: There is little knowledge of the association between physical activity (PA) level and the mortality risk post myocardial infarction (MI). Steffen/Batey et al (2000), concluded in a smaller study, that individuals who remained active or increased their level of PA post-MI had a lower risk of death. This study aimed to explore any association between PA level post-MI and all-cause mortality during follow-up in a large MI-cohort.Methods: A national cohort study including patients <75 years of age, with a diagnosis of MI between 2005-2014 (SWEDEHEART, SEPHIA-register). Self-reported PA, 6-10 weeks post-MI, (i.e. number of sessions during the past seven days with moderate and/or vigorous PA lasting ≥30 minutes) was obtained. The answers were grouped into 0-1 sessions (inactive), 2-4 sessions (moderately active) and 5-7 sessions (regularly active). First, stratified unadjusted associations were investigated. Thereafter, a multiple logistic regression was performed to control for possible confounders.Results: Complete data was obtained from 37 655 individuals (median age 63 years, 74 % men). A total of 2512 deaths occurred during a mean of 4.1 years of follow-up. The mortality rate was 17.0 cases/1000 person-years. Moderate and regular activity, was associated with a lower risk of all-cause mortality (OR 0.36, 95 % CI: 0.32-0.40 and OR 0.33, 95 % CI: 0.31-0.37) compared to being physically inactive. The OR´s remained largely unchanged when stratifying for age, gender, NSTEM/STEMI and ejection fraction. However, compared to inactive patients, physically active smokers and patients with ≤ 0.85 Eq5D had a higher OR, for subsequent death. The associations persisted in the multiple logistic regression, after adjustment for confounders (Figure 1).Conclusions: A higher level of PA, post-MI was associated with a lower risk of all-cause mortality. These results suggest that PA assessment is important post-MI, not least as an important predictor for risk of death.
