Summary

Preoperative cardiac evaluation before vascular surgery can lead to complications. Beta-blocker therapy significantly reduces cardiac events in patients with coronary artery disease (CAD).

Area of Science:

  • Cardiology
  • Vascular Surgery
  • Perioperative Medicine

Background:

  • Coronary artery disease (CAD) is common in patients needing vascular surgery, but consensus on preventing perioperative cardiac ischemic events is lacking.
  • Adverse cardiac outcomes occur frequently after infrainguinal operations, similar to aortic procedures, making findings relevant across vascular surgery types.

Purpose of the Study:

  • To analyze adverse outcomes associated with preoperative cardiac evaluation and intervention in vascular surgery patients.
  • To review current strategies for preoperative cardiac testing and management of CAD in vascular surgery.

Main Methods:

  • Retrospective analysis of 153 patients undergoing vascular procedures at the Denver Department of Veterans Affairs Medical Center.
  • Review of existing literature and ongoing trials (e.g., CARP trial) on cardiac evaluation and management strategies.

Main Results:

  • Of 42 patients with extended cardiac evaluations, 16 (38%) experienced untoward events.
  • Extensive cardiac evaluation can lead to morbidity, delays, and patient refusal of necessary vascular surgery.
  • Perioperative beta-blocker therapy has been shown to reduce adverse cardiac outcomes by 55% in vascular patients with CAD.

Conclusions:

  • The risks of preoperative cardiac evaluation and intervention must be weighed against potential benefits, considering the primary surgical indication and local complication rates.
  • Perioperative beta-adrenergic blockade is a proven strategy to mitigate cardiac risk in vascular surgery patients with CAD.
  • Further research, like the CARP trial, is needed to compare invasive cardiac intervention versus best medical care for these patients.
