Diagnostic dilemma of perioperative myocardial infarction after coronary artery bypass grafting: A review
Key result
While CABG-related perioperative morbidity and mortality are below 5%, a combination of existing diagnostic modalities is required for early and reliable detection of perioperative myocardial infarction.
Why the study?
Perioperative myocardial infarction is a significant complication after CABG, but differentiating it from expected procedure-related changes remains a diagnostic dilemma.
How are cardiac biomarkers, echocardiography, and electrocardiography used to differentiate perioperative myocardial infarction from expected procedure-related changes after CABG?

Implication
Requires combined modalities for reliable post-CABG PMI detection; leaves open development of more sensitive specific tests.
Structured PICO
How are cardiac biomarkers, echocardiography, and electrocardiography used to differentiate perioperative myocardial infarction from expected procedure-related changes after CABG?
P
Population
Patients undergoing coronary artery bypass grafting (CABG)
E
Exposure
Diagnostic modalities including cardiac biomarkers, intra- and post-operative echocardiography, and electrocardiography
O
Outcome
Detection of perioperative myocardial infarction (PMI)
A multimodality approach combining biomarkers, echocardiography, and ECG is currently required for the reliable detection of perioperative myocardial infarction after CABG, highlighting the need for more specific diagnostic tools.
Limitations
- No perfect diagnostic test for the detection of clinically meaningful perioperative myocardial infarction exists
- More sensitive and specific modalities are needed

Weidenmann et al. (2020) conducted a review in Perioperative myocardial infarction after coronary artery bypass grafting. Diagnostic modalities (cardiac biomarkers, echocardiography, electrocardiography) was evaluated on Detection of perioperative myocardial infarction. While CABG-related perioperative morbidity and mortality are below 5%, a combination of existing diagnostic modalities is required for early and reliable detection of perioperative myocardial infarction.
