Key result
Angina at 6 weeks post-MI linked to ~49% higher 1-year unplanned rehospitalization risk.
Why the study?
Race and sex disparities in post-MI angina frequency and long-term risk of unplanned rehospitalization are not well understood.
Population
11,595 MI patients treated with PCI who survived to 1 year postdischarge
Comparison
Race and sex differences in post-MI angina frequency and unplanned rehospitalization
Design
Observational cohort study using TRANSLATE-ACS data
Follow-up
1 year

Post-MI angina signals elevated rehospitalization risk warranting closer monitoring; leaves open whether targeted interventions improve outcomes.
Observational (n=11,595)
Hazard Ratio: 1.49 (95% CI 1.36–1.62)
p-value: p=<0.0001
Post-MI angina is common and strongly associated with 1-year unplanned rehospitalization, with black and female patients experiencing the highest burden of both angina and rehospitalization.
Hess et al. (2017) conducted an observational in Acute myocardial infarction (n=11,595). 6-week angina vs. No 6-week angina was evaluated on 1-year unplanned rehospitalization (HR 1.49, 95% CI 1.36-1.62, p=<0.0001). Experiencing angina at 6 weeks post-MI was strongly associated with a higher risk of 1-year unplanned rehospitalization (HR 1.49; 95% CI 1.36-1.62; P<0.0001), irrespective of race or sex.
