Evaluation Of Stent Expansion During Coronary Artery Intervention By Stent Enhancement Compared With Quantitative Coronary Angiography And Intravascular Ultrasound In Diabetic Patients

Background: Coronary stent under expansion has a crucial impact in the incidence of in-stent thrombosis and re-stenosis in cases subjected to percutaneous coronary interventions (PCI), even in the drug-eluting stent era. The current study aim to assess the accuracy of employing stent enhancement in order to identify stent expansion during coronary artery intervention compared with intravascular ultrasound (IVUS) and quantitative coronary angiography (QCA) in diabetic patients. Methods: This cross-sectional study was performed on cases scheduled for elective coronary intervention at Police Medical Complex Hospital in New Cairo. All patients of the groups were subjected to complete history taking, clinical assessment, laboratory tests, and echocardiography. Results: stent boost (or clear stent) measurements generally showed higher reliability and agreement with IVUS than QCA. stent boost measurements generally showed higher agreement with IVUS compared to QCA for both diabetic and non-diabetic cases, with the diabetic group demonstrating particularly robust agreement. Conclusion: Stent boost (or clear stent) measurements generally showed higher agreement with IVUS compared to QCA for both diabetic and non-diabetic cases, with the diabetic group demonstrating particularly robust agreement.
