Coronary disease & ACSCohort study
One-year and 5-year transition risks between major bleeding, reinfarction, and death following acute myocardial infarction in England and Wales: a population-based cohort study
- population-based cohort study
- national registry data
- multistate modelling (six-state model with nine transitions)
Authors' conclusion
In this national AMI cohort, 5-year direct death and bleeding events were more frequent than reinfarction, and the highest mortality occurred in women after AMI admission and in men following reinfarction. These transition patterns quantify the substantial absolute risks patients face post-AMI and highlight important sex-specific differences in adverse outcomes.
Study context

- 837,384 patients
- Exposure
- females vs males
Main finding
As reported in the abstract
First event post-AMI admission
bleeding
19.8%
reinfarction
8.1%
death
20.6%
Observational data: associations, not effects.

| Outcome | females | males |
|---|---|---|
| Adjusted transition IRs (×100 person-years) · 1-year | ||
| AMI admission → bleeding | 6.7 (95% CI 6.5-6.9) | 5.2 (95% CI 5.0-5.4) |
| AMI admission → reinfarction | 0.2 (95% CI 0.2-0.2) | 0.2 (95% CI 0.2-0.2) |
| AMI admission → death | 43.5 (95% CI 41.9-45.2) | 23.7 (95% CI 22.8-24.6) |
| bleeding → death | 22.2 (95% CI 20.9-23.5) | 14.5 (95% CI 13.6-15.4) |
| reinfarction → death | 41.9 (95% CI 38.1-46.0) | 25.9 (95% CI 23.8-28.3) |
| Adjusted transition IRs (×100 person-years) · 5-year | ||
| AMI admission → bleeding | 2.1 (95% CI 2.0-2.2) | 1.6 (95% CI 1.6-1.7) |
| AMI admission → reinfarction | 0.04 (95% CI 0.04-0.05) | 0.04 (95% CI 0.04-0.04) |
| AMI admission → death | 17.5 (95% CI 16.9-18.2) | 9.5 (95% CI 9.2-9.9) |
| bleeding → death | 9.7 (95% CI 9.2-10.3) | 6.3 (95% CI 5.9-6.8) |
| reinfarction → death | 17.6 (95% CI 16.0-19.4) | 10.9 (95% CI 10.0-11.9) |
Death after first event
- of those with bleeding, died
- 39.4%
- of those with reinfarction, died
- 49.9%
Transition rates by sex
- females had higher rates of transitioning to any of the five states than males
Transition rates by diabetes and ethnicity
- those with diabetes and white patients had higher transition rates than those without diabetes and black patients
