Preoperative cardiac evaluation

Area of Science:

• Cardiology
• Anesthesiology
• Vascular Surgery

Background:

• Published guidelines exist for perioperative cardiovascular evaluation before noncardiac surgery.
• Risk stratification is crucial for determining the necessity of further diagnostic testing.
• Identifying patients at high risk for cardiovascular events is a key concern.

Purpose of the Study:

• To outline a strategy for perioperative cardiovascular evaluation in noncardiac surgery.
• To emphasize the role of clinical risk factors, surgery-specific risk, and functional capacity.
• To discuss the utility of beta-adrenergic blockade in high-risk surgical patients.

Main Methods:

• Integration of clinical risk factors into the evaluation process.
• Assessment of surgery-specific cardiovascular risk.
• Evaluation of patient's functional capacity to gauge physiological stress tolerance.

Main Results:

• Beta-adrenergic blockade demonstrated efficacy in reducing perioperative risk for high-risk patients, especially those with myocardium at risk undergoing vascular surgery.
• This approach may decrease the need for more invasive procedures.
• Coronary intervention is recommended only when indicated independently of the noncardiac surgery.

Conclusions:

• A comprehensive approach integrating clinical risk, surgical risk, and functional capacity guides perioperative cardiovascular evaluation.
• Beta-adrenergic blockade is a valuable tool for mitigating perioperative risk in selected high-risk patients.
• The decision for coronary intervention should be based on the patient's cardiac condition, separate from the planned noncardiac surgery.
