Characteristics and outcomes of patients with no standard modifiable risk factors undergoing primary revascularization for acute myocardial infarction: Insights from the nationwide Japanese percutaneous coronary intervention registry
Authors' conclusion
However, although small in number, patients without SMuRFs are more likely to present with life-threatening conditions and have worse in-hospital survival.

- Participants
- 115,437 patients

Methodological detailsnationwide registry
- Nationwide registry
Main finding
As reported in the abstract
P < 0.001
Observational data: associations, not effects.
Further findings
- Prevalence of no SMuRFs — No SMuRFs
- 1.6%
Baseline presentation
- No SMuRFs: older, more left main disease, more HF, cardiogenic shock and cardiac arrest at presentation, more mechanical circulatory support and impaired post-PCI coronary flow
