Abstract
IntroductionMany publications on coronary surgery and carotid stenosis (CS) can be found, but we do not have enough information about the relationship between ischemic stroke, CS and non-coronary cardiac surgery.ObjectivesTo evaluate the incidence and risk factors associated with the stroke and CS ≥50% in patients undergoing non-coronary surgeries.ObjectivesWe assessed 241 patients, aged 40 years or older, between 2009 and 2016, operated in Santa Casa de Misericórdia de Ponta Grossa-PR, Brazil. We perform carotid Doppler in patients 40 years of age or older before any cardiac surgery as a routine. The incidence and possible risk factors for CS ≥50% and perioperative stroke were analyzed by univariate statistical analysis.Results11 patients (4.56%) presented perioperative stroke. The risk factor for stroke was CS ≥50%: OR=5.3750 (1.2909-22.3805), P=0.0208. Eighteen patients (7.46%) had CS ≥50% and their risk factors were extracardiac arteriopathy: OR=18.6607 (6.3644-54.7143), P<0.0001; COPD: OR=3.9040 (1.4491-10.5179), P=0.0071; diabetes mellitus: OR=2.9844 (1.0453-8.5204), P=0.0411; recent myocardial infarction: OR=13.8125 (1.8239-104.6052), P=0.0110; EuroSCORE II higher P=0.0056. ConclusionThe incidences of stroke and CS ≥50% were 4.56% and 7.46%, respectively. The risk factor for stroke was CS ≥50% and for CS ≥50% were extracardiac arteriopathy, COPD, diabetes mellitus, recent myocardial infarction and higher EuroSCORE II.

The risk factors for the presence of CS ≥50% can be observed in Table 3, in which the statistically significant ones were: extracardiac arteriopathy: OR=18.6607 (6.3644-54.7143), P
Summary
Many publications on coronary surgery and carotid stenosis (CS) can be found, but we do not have enough information about the relationship between ischemic stroke, CS and non-coronary cardiac surgery. Many studies have correlated carotid stenosis (CS) with coronary artery disease, coronary artery bypass grafting, and stroke risk[1,2,3,4,5,6,7,8,9,10,11,12]. The 2011 Guideline of the American Heart Association recommends special care for patients with severe carotid stenosis, cardiac surgery candidates, even if asymptomatic. That guideline recommends performing prophylactic treatment with endarterectomy or stenting in the
