Key result
Normothermic cardiopulmonary bypass during primary CABG was associated with lower rates of perioperative myocardial infarction (0.7% vs 2.0%) compared to hypothermic perfusion.
Cohort (n=1,442)

Supports normothermic cardiopulmonary bypass in primary CABG to reduce perioperative MI; adds randomized evidence favoring normothermia over hypothermia.
Jan T. Christenson (1995) conducted a cohort in Primary coronary artery bypass grafting (n=1,442). Normothermic cardiopulmonary bypass vs. Hypothermic cardiopulmonary bypass (28 °C rectal temperature) was evaluated on Perioperative mortality rate. Normothermic cardiopulmonary bypass during primary CABG was associated with lower rates of perioperative myocardial infarction (0.7% vs 2.0%) compared to hypothermic perfusion.
