Key result
Preoperative ejection fraction positively correlated with perioperative end-systolic elastance (r=0.69, p=0.03), which fell significantly following cardiopulmonary bypass (p<0.001).
Why the study?
Do preoperative ejection fraction and end diastolic pressure predict perioperative left ventricular function assessed non-invasively in CABG patients?

Do preoperative ejection fraction and end diastolic pressure predict perioperative left ventricular function assessed non-invasively in CABG patients?
Effect estimate: r = 0.69
p-value: p=0.03
Preoperative ejection fraction correlates with perioperative end-systolic elastance, which can detect systolic stunning after cardiopulmonary bypass.
Truls Myrmel Knut E. Kjørstad (2000) conducted an observational in Coronary artery disease requiring bypass surgery (n=11). Preoperative ejection fraction (EF) and end diastolic pressure (EDP) was evaluated on Correlation between preoperative EF/EDP and perioperative left ventricular function (end-systolic elastance and diastolic indexes) (r = 0.69, p=0.03). Preoperative ejection fraction positively correlated with perioperative end-systolic elastance (r=0.69, p=0.03), which fell significantly following cardiopulmonary bypass (p<0.001).
