Advances in nuclear imaging for preoperative risk assessment

Area of Science:

• Cardiology
• Cardiovascular Imaging
• Preoperative Risk Assessment

Background:

• Myocardial perfusion imaging (MPI) is a common tool for assessing patient risk before surgery.
• Its results are important for understanding long-term cardiac risk.
• MPI is most often used for intermediate-risk patients.

Purpose of the Study:

• To evaluate the utility of MPI in preoperative risk assessment across different patient risk categories.
• To highlight the importance of MPI findings for long-term risk stratification.
• To emphasize the consideration of coronary stenting's impact on surgical timing.

Main Methods:

• Review of existing literature and clinical guidelines on MPI for preoperative risk assessment.
• Analysis of MPI's applicability in low-, intermediate-, and high-risk patient groups.
• Consideration of factors influencing surgical timing post-coronary stenting.

Main Results:

• MPI is beneficial for preoperative risk assessment, particularly in intermediate-risk patients.
• MPI findings are relevant for predicting long-term cardiac risk.
• The use of MPI can be extended to selected low- and high-risk individuals.

Conclusions:

• Myocardial perfusion imaging is a valuable tool for preoperative risk assessment across a spectrum of patient risk levels.
• Clinicians should consider MPI results for long-term risk stratification.
• The influence of prior coronary stenting on the timing of noncardiac surgery must be integrated into the preoperative assessment when using MPI.
