Key result
Elective surgery was associated with a higher incidence of perioperative myocardial infarction compared to urgent surgery (13.2% vs 2.5%, P<0.01) in patients with unstable angina.

May support urgent over elective timing to lower perioperative MI in unstable angina; leaves open confirmation in randomized trials.

What factors are associated with operative mortality and perioperative myocardial infarction in patients with unstable angina pectoris undergoing myocardial revascularization?
Absolute Event Rate: 13.2% vs 2.5%
p-value: p=<0.01
In patients with unstable angina undergoing myocardial revascularization, critical triple-vessel disease is a major risk factor for operative mortality, while urgent surgery is associated with a lower incidence of perioperative MI compared to elective surgery.
John Eugene (1985) conducted a cohort in Unstable angina pectoris (n=207). Elective surgery vs. Urgent surgery was evaluated on Perioperative myocardial infarction (p=<0.01). Elective surgery was associated with a higher incidence of perioperative myocardial infarction compared to urgent surgery (13.2% vs 2.5%, P<0.01) in patients with unstable angina.
