Abstract

OBJECTIVE

(1) To report the incidence of myocardial injury in patients undergoing endovascular aortic aneurysm repair (EVAR) through the routine measurement of perioperative cardiac troponin-T (cTnT) and (2) to investigate and correlate changes in perioperative cTnT levels with any concomitant hemostatic derangement.

METHODS

Prospective study of 30 patients undergoing elective EVAR for infrarenal abdominal aortic aneurysm. Cardiac TnT was assayed at 24 hours postoperatively. Plasma thrombin antithrombin III complex (TAT), plasminogen activator inhibitor 1 (PAI-1), tissue plasminogen activator (t-PA) activity, and soluble P-selectin (sP-selectin) were assayed preoperatively and at 24 hours postoperatively.

RESULTS

Five (17%) patients demonstrated elevated cTnT levels at 24 hours; 3 patients had no clinical evidence of myocardial injury. There was a positive correlation between cTnT and TAT levels at 24 hours post-EVAR (r = .38, P = .039, Kendall-tau B = 0.26).

CONCLUSIONS

Endovascular aortic aneurysm repair is associated with a significant risk of perioperative myocardial injury that is underdetected clinically and associated with a procoagulopathic state.
