Correlation of cineangiographic and pathology findings in coronary artery disease.
In order to correlate the percent of coronary lumen reduction measured by cineangiography and by pathology, we reviewed the coronary trees of 12 patients who died of coronary heart disease. The 36 arterial segments were divided in two groups: group I showing a good correlation in its 24 segments (less than 15% difference between both methods, r = 0.90), and group II (12 segments) with a poor correlation. No significant differences were found every time there was a greater than 70% stenosis. Milder lesions have a higher rate of discrepancies, due to pathology overestimation because of collapse of the vessel and tissue shrinkage, and to the angiographic underestimation that appears when comparing the stenotic segment with a remaining presumably normal artery.
