Implication
May support anticoagulants in acute MI; extends observational data but leaves causality open for RCTs.
Key Points
- This study aims to evaluate the impact of anticoagulant therapy on survival rates in patients with myocardial infarction.
- Community-wide examination of 1,307 patients with acute myocardial infarction.
- Comparison of in-hospital case-fatality rates based on anticoagulant therapy use.
- Follow-up of hospital survivors for up to ten years.
- Adjusted in-hospital case-fatality rate was 18% for anticoagulant users vs. 31% for non-users.
- Survival advantage for anticoagulant recipients persisted across different years and hospitals.
- Long-term follow-up showed better survival for patients treated with anticoagulants compared to those not treated.
