[Algorithm of cardiac risk assessment before vascular surgery]

Area of Science:

• Cardiology
• Vascular Surgery
• Health Economics

Context:

• Vascular operations necessitate accurate cardiac risk assessment.
• Standard enlarged protocols may lead to overtreatment.
• Optimizing diagnostic pathways is crucial for patient care.

Purpose:

• To evaluate the American Heart Association (AHA) cardiac risk assessment algorithm.
• Compare its effectiveness against a standard enlarged protocol for vascular surgery patients.

Summary:

• 456 patients were analyzed; 198 with the standard protocol and 258 with the AHA protocol.
• The AHA protocol reduced unnecessary myocardial revascularization and invasive procedures by over 50%.
• The standard protocol resulted in a 2.6 times higher likelihood of unnecessary invasive procedures.

Impact:

• The AHA algorithm enhances clinical and economic effectiveness in cardiac risk assessment.
• It significantly decreases the number of invasive diagnostic procedures.
• This approach optimizes resource allocation and patient management.
