Preoperative BNP and MINS in AAA Open Repair

Prognostic Impact of Preoperative B-type Natriuretic Peptide for Predicting Myocardial Injury After Non-cardiac Surgery in Patients Who Underwent Open Repair for Abdominal Aortic Aneurysm: a Retrospective Study

The aim of this study was to investigate whether preoperative B-type natriuretic peptides serves as an independent predictor of myocardial injury after non-cardiac surgery (MINS) in abdominal aortic aneurysm open repair.

The incidence of MINS was compared between the lower BNP and higher BNP groups, and a stepwise logistic regression analysis was performed to evaluate the predictors for MINS.

Inclusion Criteria:

patients who underwent open repair with AAA from September 2010 to October 2021

Exclusion Criteria:

1. Ruptured AAA
2. Traumatic aortic injury
3. Absence of troponin-T value within 30 days of surgery
4. Diagnosis of elevation of troponin-T due to non-ischemic cause (ex: sepsis, pulmonary embolism, atrial fibrillation, cardioversion, etc.)
5. Insufficient medical records
