Abstract

Background: Cardiovascular events after orthopedic surgery may result in mortality. Therefore, predictors of early cardiovascular events after elective orthopedic surgery are required.

Aim: The aim of this study is to investigate the relationship between aortic arch calcification and 30-day major adverse cardiac events following elective orthopedic surgery.

Methods: Patients who had undergone orthopedic surgery were screened. Preoperative detailed anamnesis was taken. Echocardiography and standard chest x-ray were performed.Patients were followed in terms of perioperative 30-days major cardiac events and were classified into two groups according to development of perioperative major adverse cardiac events.Aortic arch calcification was evaluated by two cardiologists, blinded to study findings and was graded as 0 to 3 on chest x-ray.

Results: A total of 1060 patients were approached for the study participation. Of these 714 were included in the study (mean age: 70.43, 65% female). Cardiovascular events occurred in 33 patients. As compared to the patients without cardiac events, the prevalence of aortic arch calcification, coronary artery disease, hypertension, and smoking were higher in patients with cardiac events. In addition, Lee index, left ventricular end-systolic, end-diastolic and left atrial diameter were significantly higher, GFR values were significantly lower in the group with cardiac events.Multivariate regression analysis showed that smoking (OR 5.031, 95% CI 1.602 to 15.794), presence of hypertension (OR 5.133, 95% CI 1.297 to 20.308) and aortic arch calcification (OR 6.920, 95% CI 3.890 to 12.310) are independent predictors of major cardiac events within 30-day of elective orthopedic surgery.

Conclusions: Presence of aortic arch calcification is associated with development of major cardiac events within 30-days after elective orthopedic surgery.
