Cardiac Risk Stratification for Patients with Sacral Ulcers Undergoing Wound Debridement

Initial Risk Assessment

The American College of Cardiology recommends using the Revised Cardiac Risk Index (RCRI) to assess perioperative risk of major cardiac complications, assigning 1 point for each of 6 predictors: ischemic heart disease, congestive heart failure, cerebrovascular disease, high-risk surgery, insulin-dependent diabetes mellitus, and preoperative kidney dysfunction 1, 2
Patients can be classified by RCRI score: 0 factors (low risk), 1 factor (low to moderate risk), 2 factors (moderate risk), and ≥3 factors (high risk) for major cardiac complications 1
The surgical risk level of the wound debridement procedure is typically low to intermediate risk depending on extent 2
Assessing functional capacity using the Duke Activity Status Index (DASI) is important, with poor functional capacity (inability to achieve 4 METs) indicating increased risk 2

Determining if the debridement is emergency, urgent, time-sensitive, or elective is crucial, as emergency procedures carry 2-5 times higher risk than elective surgeries 2
For patients with RCRI score 0-1 and good functional capacity, proceeding with debridement without additional cardiac testing is recommended 1, 2
For patients with RCRI score ≥2 or poor functional capacity, considering additional cardiac evaluation before proceeding is necessary 1
Evaluating for unstable coronary syndromes, decompensated heart failure, significant arrhythmias, and severe valvular disease is important for patients with RCRI score ≥2 or poor functional capacity 2
Measuring B-type natriuretic peptide (BNP) levels can provide additional risk stratification 2

For patients with RCRI ≥2 or poor functional capacity, considering stress imaging or coronary CTA to further stratify risk is recommended 3
If non-invasive testing reveals high risk or is inconclusive, considering invasive coronary angiography with fractional flow reserve (FFR) measurement may be necessary 3
For patients with known coronary artery disease, evaluating current symptoms and control of ischemia is important 3

For low-risk patients (RCRI 0-1), proceeding with standard monitoring during debridement is recommended 2
For intermediate-risk patients (RCRI 2), considering perioperative beta-blockers if already on therapy and implementing enhanced monitoring during and after the procedure may be beneficial 2
For high-risk patients (RCRI ≥3), considering perioperative statin therapy, implementing comprehensive cardiac monitoring, and considering surveillance for myocardial injury after noncardiac surgery (MINS) is recommended 2

Avoid relying solely on age as a risk factor; focus on cardiac, pulmonary, and renal disease status 2
Risk scores may have poorer discrimination in patients with limited mobility or vascular disease 2
Adherence to perioperative management guidelines is often poor, representing a clear opportunity for improving quality of care 2
