What is the proper evaluation and need for further cardiac testing in a patient with sharp chest pain on exertion and rare supraventricular ectopics (SVEs) mostly in sinus rhythm (SR) undergoing preoperative anesthesia for robotic inguinal hernia repair?

Preoperative Cardiac Evaluation for Exertional Chest Pain

This patient can proceed to robotic inguinal hernia repair without additional cardiac testing, as the sharp, brief, exertional chest pain with rare SVEs on Holter monitoring does not meet criteria for active cardiac conditions requiring preoperative intervention, and inguinal hernia repair is a low-risk surgical procedure. 1

Risk Stratification

Active Cardiac Conditions Assessment

• The patient does not have unstable coronary syndromes (unstable or severe angina CCS class III-IV, recent MI within 30 days), decompensated heart failure, significant arrhythmias (high-grade AV block, symptomatic ventricular arrhythmias, supraventricular arrhythmias with uncontrolled ventricular rate >100 bpm), or severe valvular disease that would require evaluation and treatment before surgery 1, 2
• Rare supraventricular ectopics (SVEs) in sinus rhythm do not constitute a "significant arrhythmia" requiring preoperative intervention 1
• The chest pain described is sharp, lasts only minutes, self-resolves, and occurs with hiking—this atypical presentation (sharp quality, brief duration) is less consistent with classic angina, which typically presents as substernal pressure 3

Surgical Risk Classification

• Robotic inguinal hernia repair is classified as low-risk surgery (<1% risk of major adverse cardiac events) 1
• For low-risk surgical procedures, routine preoperative cardiac testing including stress testing is not indicated regardless of clinical risk factors 1

Guideline-Based Approach

Step-by-Step Algorithm

1. Emergency surgery needed? No—this is elective surgery, so systematic evaluation is appropriate 1

2. Active cardiac conditions present? No—the patient has no unstable coronary syndromes, decompensated HF, significant arrhythmias, or severe valvular disease 1, 2

3. Low-risk surgery? Yes—inguinal hernia repair is low-risk 1

4. Conclusion: Proceed to surgery without further cardiac testing 1

Supporting Evidence

• The 2014 ACC/AHA guidelines explicitly state that "routine screening with noninvasive stress testing is not useful for low-risk noncardiac surgery" (Class III: No Benefit, Level of Evidence B) 1
• A preoperative resting 12-lead ECG may be reasonable for asymptomatic patients except for low-risk surgery (Class IIb) 1
• Exercise stress testing is not indicated before noncardiac surgeries in patients who can achieve 4 metabolic equivalents (METs) without symptoms 4

Clinical Considerations

Functional Capacity

• The patient reports hiking, which suggests functional capacity likely ≥4 METs 1
• Patients with functional capacity ≥4 METs without symptoms should proceed to planned surgery 1, 5
• The ability to hike typically represents 4-10 METs of activity, which is associated with excellent perioperative prognosis 1

Chest Pain Characteristics

• Sharp chest pain lasting only minutes that self-resolves is atypical for angina 3
• Classic angina presents as substernal pressure beginning with exertion and relieved by rest, not sharp pain of brief duration 3
• The brief, self-limited nature makes unstable coronary syndrome unlikely 1

Holter Monitor Findings

• Rare SVEs in mostly sinus rhythm are benign findings that do not require treatment or delay surgery 1
• Nearly half of high-risk patients undergoing noncardiac surgery have frequent premature ventricular contractions or asymptomatic nonsustained ventricular tachycardia without increased risk of MI or cardiac death 1
• Supraventricular ectopy without uncontrolled ventricular rate or symptoms does not constitute a "significant arrhythmia" 1

Perioperative Management Recommendations

Optimization Without Additional Testing

• Ensure guideline-directed medical therapy (GDMT) is optimized 1
• Document all current medications including dosages 1, 2
• Maintain sinus rhythm and avoid tachycardia perioperatively 1
• Standard intraoperative monitoring is appropriate for low-risk surgery 1

Communication

• Avoid using the phrase "cleared for surgery" in documentation 2, 6
• Instead, document that the patient is in optimal medical condition for the planned low-risk procedure 2, 6
• Note that rare SVEs do not increase perioperative cardiac risk 1

Common Pitfalls to Avoid

• Do not order stress testing for low-risk surgery—this represents unnecessary testing that will not change management 1
• Do not delay surgery for benign arrhythmias like rare SVEs 1
• Do not misinterpret atypical chest pain (sharp, brief) as equivalent to angina requiring extensive workup 3
• Do not order tests that will not impact perioperative management decisions 2, 6
