Relationship Between the Degree of Carotid Stenosis and the Risk of Stroke in Patients Undergoing Cardiac Surgery
CS is an independent risk factor of post-operative stroke and/or TIA. This study suggests for the first time that the risk of stroke increases with the degree of severity of CS, with the greatest risk being for CS between 80-99%. The strength of this relationship and potential causality effect should be further explored in a prospective study focusing on this most at risk population.
