Preoperative and perioperative management of cardiac patients undergoing noncardiac surgery
1Department of Medicine, Baylor College of Medicine, Houston, Texas, USA.
Insights
Major noncardiac surgery poses risks for patients with coronary artery disease. While overall risks are low, high-risk procedures require careful patient assessment and consideration of preoperative interventions to minimize cardiac complications.
Area of Science:
- Cardiology
- Anesthesiology
- Cardiovascular Surgery
Background:
- Cardiac diseases, especially coronary artery disease (CAD), are primary drivers of perioperative complications in major noncardiac surgery.
- While overall risks are low, selected high-risk patients and procedures face significant complication rates.
- Current focus is on risk identification, potentially leading to over-testing in low-to-moderate risk cases.
Purpose of the Study:
- To evaluate the effectiveness of preoperative interventions in reducing perioperative cardiac risk.
- To assess the role of revascularization strategies in mitigating surgical complications.
- To highlight specific considerations for patients with cardiac devices and complex surgical histories.
Main Methods:
- Literature review focusing on risk identification, clinical assessment, and cardiac testing.
- Analysis of patient and surgical characteristics influencing outcomes.
- Exploration of preoperative interventions, including revascularization and support devices.
Main Results:
- Current practices may involve excessive testing in lower-risk patients.
- Limited research exists on the efficacy of preoperative interventions for risk reduction.
- Percutaneous or surgical revascularization as a risk-reduction strategy is not widely assessed and may be costly or risky.
- Timing of revascularization should align with noncardiac procedure urgency and risk.
Conclusions:
- Further research is needed on preoperative interventions to reduce perioperative cardiac risk.
- Careful patient selection and tailored approaches are crucial for high-risk procedures.
- Specific patient populations, including those with cardiac devices or complex surgical backgrounds, require specialized perioperative management.
Abstract:
Cardiac diseases, particularly coronary artery disease and its risk factors, are associated with the majority of perioperative complications in patients undergoing major noncardiac surgery. Risks are remarkably low overall, yet for selected patients undergoing high-risk procedures, the chances of complications remain reasonably high. The literature has focused largely on identifying patients in whom complications are most likely to occur, using clinical assessment, including RFI, specialized cardiac testing, and perioperative monitoring. Characteristics of the patient and the surgery both influence outcomes. Current practices may have swung toward excessive testing, especially in patients whose surgical risks are low or moderate. Surprisingly little attention has been devoted to the evaluation of preoperative interventions for reducing perioperative risk. Some observations support the feasibility of performing noncardiac surgery in some high-risk groups using support devices or temporizing techniques. The general application of percutaneous or surgical revascularization as a means of reducing perioperative risk has not been assessed and to date represents an expensive and perhaps risky strategy. In patients who satisfy the usual symptomatic or prognostic criteria for coronary revascularization, its timing should depend on the urgency and risk of the noncardiac procedure. Finally, patients with cardiac devices--pacemakers, prosthetic valves, implantable debrillators, and antitachycardia devices--and survivors of congenital and transplant surgery have specific needs that require careful attention, going beyond the usual vigilance required in the perioperative period.
