Key result
Acute coronary angiography after CABG was associated with higher 30-day mortality (7% vs 2%, p=0.002) and lower 5-year survival (77% vs 87%, p=0.043) compared to no angiography.
Why the study?
Is acute coronary angiography after CABG associated with increased short-term and long-term mortality?
Observational (n=4,446)
Is acute coronary angiography after CABG associated with increased short-term and long-term mortality?
Absolute Event Rate: 7% vs 2%
p-value: p=0.002
Acute coronary angiography after CABG is a rare event (2%) but identifies a high-risk cohort with significantly increased short-term and long-term mortality.
No takes yet. Share an insight, caveat, or question.
May indicate higher-risk patients selected for acute post-CABG angiography; leaves open causality and need for prospective confirmation.
Hultgren et al. (2016) conducted an observational in Coronary artery bypass grafting (CABG) (n=4,446). Acute coronary angiography vs. No acute coronary angiography was evaluated on Thirty-day mortality (p=0.002). Acute coronary angiography after CABG was associated with higher 30-day mortality (7% vs 2%, p=0.002) and lower 5-year survival (77% vs 87%, p=0.043) compared to no angiography.
