Correlation of Angiographic Findings and Clinical Presentations in Unstable Angina


ABSTRACT:BACKGROUND:Unstable angina is usually related to acute thrombosis superimposed on a disrupted plaque. The highest;level of Braunwald classification of unstable angina can be used to assess the severity of clinicalpresentation. However the highest classes have not been directly correlated with thrombotic and complexlesions.OBJECTIVE:The study was done to clarify the correlation between angiographic findings and the most acute and / orsevere clinical presentation in unstable angina.PATIENTS AND METHOD:We conducted a prospective study of 110 patients of unstable angina at Ibn-Albitar Center for CardiacSurgery. All of these patients underwent cardiac catheterization, culprit lesion was identified in 80patients and in 30 patients there was no an identifiable culprit lesion .Complex lesions including complexmorphology, intracoronary thrombus, or total occlusion were also quantitatively analyzed andThrombolysis in Myocardial Infarction (TIMI) flow grade was assessed. Patients were classifiedaccording to Braunwald classification in instable angina .We compared patients with and those with noculprit lesions in regarding Braunwald classification. We sequentially compared the highest Braunwaldclasses II, C, 3 with classes
