[Algorithm of cardiac risk assessment before vascular surgery]
Insights
The American Heart Association (AHA) cardiac risk algorithm significantly reduces unnecessary invasive procedures for vascular surgery patients. This cardiac risk assessment improves clinical and economic effectiveness compared to standard protocols.
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.
The Object:
to detect the informative value of algorithm of cardiac risk assessment recommended by American Heart Association compared with original standard enlarged protocol. Overall 456 patients underwent vascular operations. First group consisted of 198 patients who were examined according original enlarged protocol; other 258 patients (2nd group) were examined with AHA protocol. At 1st group 41% patients didn't need myocardial revascularization (according coronarography results), preventive coronary bypass surgery was performed at 32% patients. At 2nd group coronarography was performed at 133 (51%) patients according risk factors stratification and stress-examination results. Preventive coronary bypass surgery was performed at 97 patients; 27 patients refused this recommendation. Enlarged protocol increases in 2.6 times the odds of unnecessary invasive procedure. It is concluded that AHA algorithm permits to reduce in 2 times and more the number of invasive diagnostic procedures compared with standard enlarged protocol; AHA algorithm increases the clinical and economic effectiveness.
