Predictors of mortality and mortality from cardiac causes in the bypass angioplasty revascularization investigation...

Area of Science:

• Cardiology
• Interventional Cardiology
• Clinical Trials

Background:

• Uncertainty exists regarding long-term mortality differences between PTCA and CABG in patients suitable for both.
• Patient demographics, clinical status, and angiographic findings may influence outcomes.

Purpose of the Study:

• To identify factors influencing long-term mortality in patients undergoing PTCA versus CABG.
• To explore treatment interactions with patient characteristics.

Main Methods:

• Analysis of the Bypass Angioplasty Revascularization Investigation (BARI) trial and registry data.
• Inclusion of 3610 patients eligible for both PTCA and CABG.
• Multivariate Cox models to assess 5-year and cardiac mortality.

Main Results:

• Insulin-treated diabetes was associated with higher mortality with PTCA compared to CABG.
• ST-elevation myocardial infarction was linked to higher cardiac mortality with CABG versus PTCA.
• High mortality risk factors included insulin-treated diabetes, heart failure, kidney failure, older age, and Black race.

Conclusions:

• Identified variables can aid in selecting revascularization procedures.
• Risk stratification for long-term mortality is improved by considering specific patient factors.
