[What pre-operative explorations should be performed in a cardiac patient scheduled for non cardiological surgery?]

Area of Science:

• Cardiology
• Anesthesiology
• Internal Medicine

Background:

• Preoperative assessment of cardiac patients undergoing non-cardiac surgery is crucial for managing risks.
• Coronary artery disease is a frequent concern, potentially leading to severe postoperative complications.
• Effective management requires evaluating clinical risk factors and pre-test probability of complications.

Purpose of the Study:

• To outline a strategy for preoperative cardiac risk assessment in patients undergoing non-cardiac surgery.
• To guide the selection of appropriate diagnostic tests based on estimated cardiac risk.
• To inform treatment decisions for coronary artery disease and other cardiac pathologies.

Main Methods:

• Clinical evaluation and resting electrocardiogram (EKG) form the initial assessment.
• Non-invasive tests like radionuclide angiography and stress echocardiography are used for higher-risk patients.
• Coronary angiography is employed if non-invasive tests indicate significant coronary stenosis.

Main Results:

• Low cardiac risk patients require minimal preoperative planning.
• Higher cardiac risk necessitates invasive examinations to quantify risk.
• Positive findings may lead to interventions like bypass grafting or angioplasty if beneficial.

Conclusions:

• Risk stratification guides the intensity of preoperative cardiac evaluation.
• Echocardiography is key for assessing left ventricular function and valvular disease.
• Utilizing risk classifications aids in patient management and resource allocation.
