Summary

This summary is machine-generated.

Intermediate-risk patients most benefit from preoperative cardiac testing and coronary revascularization before major surgery. This approach improves long-term survival for this specific group, guiding clinical decisions.

Area of Science:

Cardiology
Vascular Surgery
Clinical Risk Stratification

Background:

Guidelines recommend non-invasive cardiac testing before major non-cardiac surgery.
Data is lacking to identify patients who truly benefit from preoperative cardiac testing and coronary revascularization (CR).

Purpose of the Study:

Identify predictors for patients most likely to benefit from preoperative cardiac testing and CR.
Develop a risk score to stratify patients undergoing major vascular surgery.

Main Methods:

Retrospective analysis of 624 major vascular surgery patients.
Correlated preoperative thallium scanning (PTS) and CR with long-term survival (3-15 years).
Developed a Long-Term Survival Score (LTSS) based on seven independent predictors.

Main Results:

Seven predictors (age, diabetes, cerebrovascular disease, ischemic heart disease, heart failure, ECG ST-depression, renal insufficiency) identified.
LTSS stratified patients into low (0-1), intermediate (2-3), and high (>=4) risk groups.
Intermediate-risk patients showed improved long-term survival after CR (HR=0.48), unlike low- or high-risk groups.

Conclusions:

Intermediate-risk patients (LTSS 2-3) are the primary beneficiaries of preoperative cardiac testing and CR.
The findings aid in selective application of cardiac testing and CR to optimize surgical outcomes.
