Key result
CCTA and CAC match or outperform traditional imaging for predicting MACE risk before noncardiac surgery.
Why the study?
Perioperative and long-term postoperative MACE are leading causes of morbidity and mortality in noncardiac surgery, creating a need to evaluate CCTA and CACS for direct anatomical assessment in preoperative risk stratification.
Does coronary computed angiography and coronary artery calcium score improve risk stratification for major adverse cardiovascular events in patients undergoing noncardiac surgery?
Does coronary computed angiography and coronary artery calcium score improve risk stratification for major adverse cardiovascular events in patients undergoing noncardiac surgery?
CCTA and CACS offer reliable anatomical assessment for preoperative cardiovascular risk stratification in noncardiac surgery, potentially outperforming traditional stress imaging.

May support CCTA or CACS for preoperative MACE stratification; leaves open need for prospective validation before practice change.
Perioperative and long-term postoperative major adverse cardiovascular events (MACE) are a leading cause of morbidity and mortality in patients undergoing noncardiac surgery. In selected high-risk patients, when information about cardiovascular status may influence surgical decisions, preoperative risk stratification is reasonable, with stress imaging being the preferred method. Coronary computed angiography (CCTA) and coronary artery calcium score (CACS) offer direct anatomical assessment of atherosclerotic coronary arteries and help gauge the extent and severity of coronary artery disease. Strong evidence supports that CCTA and CACS, either alone or in combination, are reliable methods for assessing the risk of both perioperative and long-term postoperative MACE, often demonstrating equal or superior prognostic performance compared to traditional imaging tools. Moreover, integrating CCTA or CACS into standard preoperative imaging protocols further enhances perioperative risk prediction and improves the ability to accurately stratify patients. Future research is needed to better define the role of CCTA and CACS in preoperative cardiovascular risk evaluation of patients undergoing noncardiac surgery.

Kyriakoulis et al. (2025) conducted a review in Patients undergoing noncardiac surgery. Coronary computed angiography (CCTA) and coronary artery calcium score (CACS) vs. Traditional imaging tools was evaluated on Perioperative and long-term postoperative major adverse cardiovascular events (MACE). Coronary computed angiography and coronary artery calcium score demonstrate equal or superior prognostic performance compared to traditional imaging for assessing MACE risk before noncardiac surgery.
