Correlation of Angiographic Findings and Clinical Presentations in Unstable Angina

Abstract

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 clinical presentation. However the highest classes have not been directly correlated with thrombotic and complex lesions. OBJECTIVE: The study was done to clarify the correlation between angiographic findings and the most acute and / or severe clinical presentation in unstable angina. PATIENTS AND METHOD: We conducted a prospective study of 110 patients of unstable angina at Ibn-Albitar Center for Cardiac Surgery. All of these patients underwent cardiac catheterization, culprit lesion was identified in 80 patients and in 30 patients there was no an identifiable culprit lesion .Complex lesions including complex morphology, intracoronary thrombus, or total occlusion were also quantitatively analyzed and Thrombolysis in Myocardial Infarction (TIMI) flow grade was assessed. Patients were classified according to Braunwald classification in instable angina .We compared patients with and those with no culprit lesions in regarding Braunwald classification. We sequentially compared the highest Braunwald classes II, C, 3 with classes
