[Correlations between clinical picture and coronary angiography in unstable angina]

In a one year period (from 01.07. 1993 to 30. 06. 1994) 103 patients were admitted to the Central Intensive Care Unit of the Albert Szent-Györgyi Medical University with the diagnosis of unstable angina. In this cohort of patients the authors assessed the correlation of clinical and angiographic data. Significant coronary artery disease was found in 84% (85 patients), single-vessel disease in 23% (24 patients), double-vessel disease in 38% (29 patients), triple-vessel disease in 20% (21 patients), left main stenosis in 8% (8 patients). The culprit lesion was determined in 73 cases. The distribution of the culprit lesion severity was the following: 50-70% in 17% (12 cases), 70-90% in 27% (20 cases), greater than 90% in 44% (32 cases), 100% in 12% (9 cases). Simplex lesions were seen in 43 cases, complex lesions in 9 cases, diffuse irregularities in 5 cases and total occlusions in 9 cases. Abnormalities indicating intracoronary thrombin-us were seen on 5 coronarograms. No correlation could be demonstrated between the clinical classes according to Braunwald and the angiographic morphology.
