title: [Clinical presentation and coronary angiographic results in unstable angina pectoris].
abstract: The syndrome "unstable angina" (UA) covers a broad spectrum of patients. In this study we tried to determine the relationship between the severity of UA and angiographic findings. We evaluated 1000 consecutive patients undergoing coronary angiography. Those with the clinical diagnosis "UA" were included in the study. In a retrospective analysis of their records we categorized them, using the Braunwald-classification for determination of the severity of the disease. 352 patients were include, 209 men and 143 women, the mean age was 65 years. 47% met Braunwald-Class I, 26% Class II and 27% Class III. Coronary single-vessel disease was present in 29%, two-vessel disease in 20%, three-vessel disease in 25%, normal coronaries in 13% and coronary atherosclerosis without critical narrowing in 13%. Left ventricular function was preserved in 72%, mild systolic dysfunction was found in 10%, moderate in 13% and severe in 5%. There was no overall correlation between clinical presentation (Braunwald-Classes) and angiographic findings. Women showed a similar distribution of Braunwald-Classes, but significantly more coronary arteries without critical obstruction. In patients with reduced systolic function the percentage of multi-vessel disease was significantly higher, the percentage without relevant coronary artery narrowing was significantly lower. 1) The lack of overall correlation between clinical presentation and angiographic findings supports the importance of coronary angiography in the evaluation of patients with UA. 2) The assessment of women with chest pain is more difficult than of men with regard to coronary heart disease. 3) UA in patients with impaired left ventricular function is a predictor of severe coronary artery disease.
