Comparative Study of Perioperative Cardiac Injury in Patients With Functional Adrenal Tumors

Dynamic Monitoring and Comparative Study of Perioperative Cardiac Injury in Patients With Functional Adrenal Tumors

The main goal of this study is to follow patients with functional adrenal tumors during the time before and after their surgery.

The main questions it aims to answer are:

• What heart and blood pressure changes do patients with different types of adrenal tumors have before surgery?
• What factors affect how the heart and blood pressure recover after surgery?
• Do the heart and blood pressure conditions before surgery influence recovery and the risk of heart or brain problems after surgery?

Patients will have heart ultrasound checks and health monitoring before and after surgery. The results will help doctors choose the right medicines before surgery, better understand possible risks during the operation, and make safer treatment plans for patients with functional adrenal tumors.

Inclusion Criteria:

• Patients diagnosed in the Department of Urology, Peking University First Hospital with pheochromocytoma and paraganglioma (PPGL), primary aldosteronism (PA), or Cushing syndrome (CS);
