What is the most common cause of death following vascular surgery?

Myocardial infarction is considered the most common cause of death following vascular surgery due to several factors linked to the stress of surgery and the underlying conditions of the patients undergoing such procedures. Patients often have multiple risk factors for cardiovascular diseases, and the surgical process itself can provoke hemodynamic changes that increase the likelihood of a heart attack. Additionally, stress responses from surgery can lead to an increase in myocardial oxygen demand combined with a potential decrease in supply, especially in the context of already compromised cardiac function.

The surgical process may also involve manipulation of vessels and increased intraoperative blood loss, which can contribute to the strain on the heart. Furthermore, postoperative complications, including arrhythmias, can further raise the risk of myocardial infarction in vulnerable patients.

Understanding these dynamics emphasizes the importance of preoperative assessment and management of cardiovascular risks in patients scheduled for vascular surgery to mitigate this significant postoperative risk.
