Predictors for New Native-Vessel Occlusion in Patients with Prior Coronary Bypass Surgery: A Single-Center Retrospective Research

Blog Article

Objectives.Chronic total occlusion (CTO) is prevalent in patients with prior coronary artery bypass grafting (CABG).However, data available concerning the prevalence of new-onset CTO of native vessels in patients with prior CABG is limited.Therefore, the objective of the study is to determine predictors for new native-vessel occlusion in patients with prior coronary bypass surgery.Methods.

354 patients with prior CABG receiving follow-up kt196 torque converter angiography are selected and analyzed in the present study, with clinical and angiographic variables being analyzed by logistic regression to determine the predictors of new native-vessel occlusion.Results.The overall new occlusion rate was 35.59%, with multiple CTOs (42.06%) being the most prevalent (LAD 24.

60% and RCA 18.25%, respectively).Additionally, current smoking (OR: 2.67; 95% CI: 2.60 to 2.

74; p=0.01), reduced ejection fraction click here (OR: 1.76; 95% CI: 1.04 to 2.97; p=0.

04), severe stenosis (OR: 3.65; 95% CI: 2.55 to 5.24; p=0.01), and diabetes mellitus (OR: 1.

86; 95% CI: 1.34 to 2.97; p=0.04) serve as the independent predictors for new native-vessel occlusion.Conclusion.

As to high incidence of postoperative CTO, appropriate revascularization strategies and postoperative management should be taken into careful consideration.
