How do preoperative cardiac risk factors influence outcomes in patients undergoing prophylactic carotid endarterectomy for asymptomatic bruit?
How do preoperative cardiac risk factors influence outcomes in patients undergoing prophylactic carotid endarterectomy for asymptomatic bruit?
Cardiac morbidity and mortality significantly impact long-term outcomes after prophylactic carotid endarterectomy, suggesting the procedure should be reserved for patients with minimal or medically optimizable cardiac risk.
Cardiac risk factors associated with most late deaths after prophylactic CEA; leaves open whether optimization improves survival in asymptomatic patients.
We assessed the influence of preoperative cardiac risk factors in 57 patients undergoing 70 prophylactic carotid endarterectomies (PCE) and found that: (1) 47 (83%) had at least one cardiac risk factor and (2) nine of 15 deaths occurring in the late follow-up period (40 to 120 months) were due to cardiac causes. Perioperatively, one patient sustained a mild stroke. Although the cumulative stroke-free occurrence rate was kept to less than 6% over the five-year period, cardiac morbidity and mortality greatly influenced the quality of life after PCE. Therefore, PCE is suggested only for patients who have minimal preoperative cardiac risk factors or for those patients whose cardiac risk factors can be improved by medical therapy.
