Coronary disease & ACSCase-control study
Outcomes after a first acute myocardial infarction in patients with or without congenital heart disease
- Nationwide case-control study
- matched (1:10)
- Mean follow-up 6.5 years (ACHD) and 7.3 years (controls)
Authors' conclusion
This study suggests that survival rates and the incidence of recurrent AMI in ACHD patients are similar to those of controls.
Study context
- Population
- Adults with a first acute MI, nationwide, 2000–2022matched cohort
- Participants
- 213 vs 2,092
- Comparison
- ACHD vs matched controls without congenital heart disease
- ACHDn = 213
- Controlsn = 2,092reference
- Outcome
- All-cause mortality and recurrent acute MI
Main finding
As reported in the abstract
All-cause mortality and recurrent AMI · 1 year
- No significant difference in mortality or recurrent acute myocardial infarction (AMI) rates at 1 year between ACHD and matched controls
- matched cohort
Observational data: associations, not effects.
