Coronary artery disease (CAD) is common in peripheral arterial disease patients undergoing vascular surgery. Preoperative cardiac evaluation should guide management, but prophylactic interventions are not routinely recommended.

Area of Science:

  • Cardiology
  • Vascular Surgery
  • Perioperative Medicine

Background:

  • Coronary artery disease (CAD) is prevalent in patients with peripheral arterial disease (PAD) and significantly contributes to morbidity and mortality following vascular operations.
  • Clinical risk assessment tools aim to stratify patients into low, intermediate, or high cardiac risk categories for adverse cardiac events.
  • For low-risk patients, additional cardiac testing provides minimal incremental information beyond clinical scoring.

Purpose of the Study:

  • To evaluate the utility of preoperative cardiac work-up in patients undergoing vascular surgery.
  • To determine the appropriate management strategy for patients with varying degrees of cardiac risk.
  • To assess the role of prophylactic coronary interventions in enhancing surgical safety.

Main Methods:

  • Review of clinical risk assessment strategies for perioperative cardiac events.
  • Analysis of the impact of additional cardiac testing on patient management.
  • Consideration of the timing and indication for coronary angiography and revascularization.

Main Results:

  • High-risk patients may require coronary angiography, intensive monitoring, or surgical modification, but further testing is only indicated if it alters management.
  • Intermediate-risk patients may benefit from further cardiac investigations, including coronary arteriography, if vascular surgery can be delayed for revascularization.
  • The urgency of vascular surgery (e.g., threatened limb) often precludes extensive preoperative cardiac work-up.

Conclusions:

  • Preoperative cardiac evaluation should be tailored to individual patient risk and the potential to alter management.
  • Prophylactic coronary artery bypass grafting (CABG) or percutaneous transluminal coronary angioplasty (PTCA) should not be routinely performed to enhance vascular surgery safety.
  • Decisions regarding coronary interventions should be based on cardiac symptoms and coronary anatomy, not solely on the planned vascular procedure.
