Abstract

Background: Every year, millions of noncardiac surgeries occur, with 25% of patients aged 45 or older suffering from atherosclerosis-related cardiovascular disease and 45% experiencing hyperlipidemia and hypertension, all of which correlate with perioperative cardiovascular events.

Aim and objectives: Evaluation of the ability of cardiac biomarkers and stress tests to estimate the risk of noncardiac operations.

Subjects and methods: We performed this prospective observational research on 60 patients selected from the outpatient cardiovascular clinics of Al Azhar University Hospitals between February 2023 and December 2023. We divided them into survivors and deceased groups based on their respective outcomes.

Result: Stress ECG showed positive findings in 75% of the patients, negative findings, and inadequate results in 6.7% of each, while 11.7% showed inconclusive results. Based on dobutamine stress echocardiography, 8.3% of the patients showed high function capacity, and 10% showed low function capacity. Regarding the outcome, 81.7% of the patients survived, and 18.3% died ( 60% of them died due to myocardial infarction, 30% of them died due to stroke, 10% of them died due to pulmonary embolism). There wasn't statistically significant variance among survived and non-survived subjects regarding stress ECG and dobutamine stress echocardiography.

Conclusion: The cardiac biomarkers BNP and CK-MB have played a significant role in the cardiac risk stratification of cases scheduled for noncardiac surgery. There are no benefits to the stress ECG when used to compare patients' outcomes after noncardiac surgery.
