If noninvasive testing is negative but the patient remains high-risk due to persistent symptoms, what is the recommended course of action?

• A. Proceed to noncardiac surgery with standard care
• B. Consider further evaluation or revascularization if risk remains
• C. Discharge the patient without further testing
• D. Initiate dialysis

Answer: (B)

When evaluating a patient for noncardiac surgery, a negative noninvasive test does not completely rule out significant coronary disease in someone who remains high‑risk because of persistent symptoms. If ischemic symptoms persist, ongoing myocardial risk remains, so the next step is to pursue further evaluation and consider revascularization if risk continues. Noninvasive tests can miss disease (false negatives) in certain patients, such as those with multivessel disease or baseline ECG abnormalities, or when symptoms are active. In a high-risk patient with persistent angina or other signs of ischemia, invasive testing with coronary angiography can define the coronary anatomy more definitively. If substantial obstructive disease is found and the patient is suitable for revascularization, performing PCI or CABG before the planned noncardiac surgery can reduce perioperative cardiac events. If revascularization isn’t feasible or the surgery is urgent, optimize medical therapy and carefully weigh the timing of surgery. Thus, the appropriate course is to pursue further evaluation or revascularization if the risk persists, rather than proceeding with surgery, discharging the patient, or initiating unrelated treatments.
