Why the study?
Does the presence of chronic total occlusion (CTO) in a non-infarct-related artery impact 1-year mortality in STEMI patients undergoing primary PCI?
Population
2020 consecutive patients referred with STEMI between 2006 and 2011, categorized into single vessel disease…
Comparison
Primary percutaneous coronary intervention vs Comparison between single vessel disease, MVD…
Design
Cohort
Follow-up
1 year
Key result
In patients with STEMI, chronic total occlusion was not independently associated with 1-year mortality (HR 1.07; 95% CI 0.66-1.73; p=0.78) after adjusting for ejection fraction and renal function.

CTO in STEMI was associated with worse survival; leaves open whether revascularization improves outcomes.

Hazard Ratio: 1.07 (95% CI 0.66–1.73)
Absolute Event Rate: 28.1% vs 7.3%
p-value: p=0.78
Bataille et al. (2012) conducted an observational in ST-elevation myocardial infarction (STEMI) (n=2,020). Chronic total occlusion (CTO) vs. No CTO was evaluated on 1-year mortality (HR 1.07, 95% CI 0.66-1.73, p=0.78). In patients with STEMI, chronic total occlusion was not independently associated with 1-year mortality (HR 1.07; 95% CI 0.66-1.73; p=0.78) after adjusting for ejection fraction and renal function.
