Abstract:Objective To investigate the influence of coronary artery ectasia(CAE) on the prognosis of patients with coronary heart disease.Methods A total of 86 patients with coronary artery dilatation confirmed by percutaneous coronary angiography in Suqian People′s Hospital from January 2012 to July 2019 were retrospectively collected, among them 79 patients with CAE complicated with coronary heart disease were selected as the study group.The control group consisted of 48 patients with coronary atherosclerotic heart disease without CAE.Demographic data, cardiovascular risk factors, hospitalization data, major cardiovascular events during follow-up were collected. Results There was no significant difference in basic demographic data, cardiovascular risk factors, coronary angiography characteristics and incidence of complications during hospitalization between the two groups (P>0.05).The number of patients without PCI and the number of stents implanted in the study group were less than those in the control group (P<0.05).There was no significant difference in major cardiovascular events and readmission rate between the two groups during the follow-up period (P>0.05). ConclutionCAE is not common, but it increases the complexity of coronary lesions, leading to a reduction in the number of percutaneous coronary treatment and stent implantation.But in general, CAE has no significant effect on the prognosis of patients with coronary heart disease.
