Implementation of high-sensitivity cardiac troponin assays and the recommendations of the Universal Definition of Myocardial Infarction identified patients at high-risk of cardiovascular and noncardiovascular events but was not associated with consistent increases in treatment or improved outcomes.

Primary result
MI or CV death · 1 year
Cause-specific hazard ratio

95% CI 5.12–6.22
Type 1 MI vs No myocardial injury

As reported in the abstract
Secondary outcomes
| Outcome | Cause-specific HR (95% CI) | |
|---|---|---|
| Non-CV death · 1 yearAcute myocardial injury vs No myocardial injury · highest in acute myocardial injury | 2.65 (2.33–3.01) | |
| MI or CV death in type 1 MI, after vs before implementation | 1.00 (0.82–1.21) | |
| 0.20.5125Cause-specific hazard ratio (log scale) |
Increase in diagnoses after implementation
- MI or CV death in type 1 MI, after vs before implementation: despite modest increases in antiplatelet therapy and coronary revascularization
Investigation, treatment and outcomes in type 2 MI and myocardial injury
- Increased recognition did not lead to changes in investigation, treatment or outcomes
