Estenosis carotídea asociada a cardiopatía isquémica en pacientes tratados con revascularización miocárdica

Abstract

Introduction and objectivesCarotid stenosis (CAS) is an important factor in neurological complications after coronary artery bypass grafting (CABG). Current guidelines recommend that patients older than 70 years with symptoms of neurological disease should be screened for CAS prior to surgery; however, this remains controversial. The objective of this study was to determine the frequency of CAS in patients undergoing CABG, in addition to assessing its influence on neurological events and mortality. MethodProspective study where carotid ultrasound was performed in asymptomatic patients prior to CABG. Patients were divided based on the degree of carotid stenosis (less than 50%, 50-70%, and greater than 70%) and classified based on age into 3 groups (less than 60, 60-70, and greater to 70 years). Median, maximum and minimum were measured in continuous numerical variables and percentage in categorical ones. Regression analysis was applied to selected parameters to identify risk factors for significant CAS. ResultsOnly one patient presented cerebral vascular event after CABG, we did not observe association of CAS with mortality or hospital time, however, an association was found with the affected vessels and the number of comorbidities. ConclusionsCAS is common in patients with ischemic coronary disease and is a marker of increased risk of cardiovascular events, so we believe that detecting it is important for preoperative risk stratification.
