Key result
Waiting for coronary revascularization is associated with a ~2% pre-procedural death rate.
Why the study?
The occurrence of death, acute myocardial infarction, and hospitalization among patients waiting for coronary revascularization was not well described.
Population
718 patients on the waiting list for coronary revascularization in western Sweden
Comparison
Patients waiting for coronary artery bypass grafting or percutaneous transluminal coronary angioplasty
Design
Observational cohort study
Follow-up
Time on waiting list prior to revascularization

Waiting for revascularization carries measurable event risk; extends observational data on waitlist hazards but requires prospective trials before practice change.
Observational (n=718)
Patients waiting for coronary revascularization face a notable risk of adverse events, including a 2.1% mortality rate and a 29% hospitalization rate prior to the procedure, with higher risks in older patients, diabetics, and those with low ejection fraction.
Bengtson et al. (1996) conducted an observational in Coronary artery disease requiring revascularization (n=718). Waiting for coronary revascularization was evaluated on Death prior to revascularization. Waiting for coronary revascularization was associated with a 2.1% rate of death and a 1.7% rate of non-fatal acute myocardial infarction prior to the procedure.
