Prognostic Role of Early Cardiac Magnetic Resonance in Myocardial Infarction With Nonobstructive Coronary Arteries
Authors' conclusion
In MINOCA with early CMR execution, the %LGE and abnormal T2 mapping values were identified as independent predictors of adverse cardiac events at ∼3.0 years of follow-up.
Study context
- Population
- Myocardial infarction with nonobstructive coronary arteries (MINOCA) patients with early cardiac magnetic resonance (CMR), excluding acute myocarditis, takotsubo, cardiomyopathies and other nonischemic etiologies, January 2017 to October 2021437 assessed
- Participants
- 198 patients
- Exposure
- CMR phenotypes: Late gadolinium enhancement (LGE)+/M+ vs LGE-/M+ vs LGE-/M-
- LGE+/M+n = 116
- Outcome
- MACE
- Follow-up
- Mean 33.7 ± 12.0 months
Methodological detailsCMR performed on average 4.8 ± 1.5 days from acute presentation
- CMR performed on average 4.8 ± 1.5 days from acute presentation
Main finding
As reported in the abstract
Observational data: associations, not effects.
Further findings
Independent predictors of major adverse cardiovascular events (MACE) (multivariable Cox regression)
| HR (95% CI) | P value | ||
|---|---|---|---|
| %LGE | 1.123 (1.064–1.185) | P < 0.001 | |
| T2 mapping values | 1.190 (1.145–1.237) | P = 0.001 | |
| 0.512Hazard ratio (log scale) |
- Extension of myocardial damage at CMR significantly greater in patients who developed MACE
