[Morphology of coronary vessels in coronary heart disease. An analysis of 930 coronary angiograms].
Coronary anatomy was analyzed in 930 patients who underwent coronary arteriography because of coronary artery disease. There was a slight predominance of single vessel disease, whereas double and triple vessel disease were equally distributed. A left main (LM) lesion was found in 5.2%, with an additional right coronary artery lesion in 3.3%. The left anterior descending (LAD) artery was involved most frequently, followed by the right coronary artery (RCA) and left circumflex (Cx). The LAD demonstrated more often a proximal stenosis than the RCA and Cx. If the LM is associated with a RCA-stenosis then the LAD and Cx are involved more commonly, suggesting a more advanced disease in all major vessels. The analysis of ventricular function revealed a significant deterioration according to the number of diseased vessels. If the LM is associated with a RCA lesion, then the hemodynamics are similar to a 3-vessel disease, whereas isolated LM lesions are associated with good ventricular function according to the lesser degree of coronary sclerosis. The deterioration of the hemodynamics in correlation with coronary vessel involvement is significant, however due to the large standard deviations conclusions for the individual patient can not be drawn.
