What is the accuracy of angiographic determination of left main coronary arterial narrowing?
The accuracy of angiographic determination of left main coronary arterial narrowing has been demonstrated in several studies. In a study conducted by Isner et al. (1981), the accuracy of angiographic determination of left main coronary arterial narrowing was found to be 84%, with a correlative histologic analysis in 28 patients. Cameron et al. (1983) also found that the accuracy of angiographic determination of left main coronary arterial narrowing was approximately 80%. These studies demonstrate the accuracy of angiographic determination of left main coronary arterial narrowing, which can be used to assess the prognosis of patients with coronary artery disease.
