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
