Pre-Bypass Myocardial Ischaemia in Patients Undergoing Coronary Artery Surgery
Key result
Pre-bypass myocardial ischaemia occurred in 13% of patients undergoing elective coronary artery surgery, and none of the patients with postoperative myocardial infarction had prior ST depression.
Population
100 patients undergoing elective coronary artery surgery
Design
Cohort
Follow-up
From arrival in anaesthetic room until postoperative period

Implication
Pre-bypass ST depression should not guide postoperative MI risk assessment; leaves open the value of ischemia monitoring in elective coronary surgery.

Incidence of pre-bypass myocardial ischaemia (significant ST depression on ECG)surrogate
Pre-bypass myocardial ischaemia (ST depression) occurred in 13% of patients undergoing elective coronary artery surgery, but was not associated with postoperative myocardial infarction in this cohort.
Cite This Study
Davies et al. (1990) conducted an observational in Elective coronary artery surgery (n=100). Pre-bypass period was evaluated on Incidence of pre-bypass myocardial ischaemia (significant ST depression). Pre-bypass myocardial ischaemia occurred in 13% of patients undergoing elective coronary artery surgery, and none of the patients with postoperative myocardial infarction had prior ST depression.
