Abstract
Coronary atherosclerosis was induced in Yorkshire swine by diet-induced hyperlipidemia and balloon intimal abrasion of a coronary artery. Severe stenoses pathologically similar to the lesions of human atherosclerosis were seen after 8 months of the atherogenic regimen. To examine the relationship between the angiogram and pathology in the assessment of the extent and location of coronary atherosclerosis, antemortem angiographic results were compared with results of pathologic examination. Vernier caliper measurements of the coronary angiogram were compared with results of morphometric evaluation of perfusion-fixed coronary arteries. Isolated focal stenoses were correctly localized and quantified, as were focal lesions within vessels diffusely diseased. Both overestimation and underestimation of lesions occurred at bifurcation sites. Diffuse disease without focal stenoses was not well demonstrated angiographically. Vessels that were angiographically thought to be normal or only minimally diseased demonstrated significantly larger lumens angiographically than pathologically. This is believed to be due to fixation and paraffin-processing artifact, even though fixation was performed by perfusion at physiologic pressure. The demonstration of an excellent correlation between the luminal size as determined angiographically and morphometrically at sites of focal obstruction confirms the value of quantitation of coronary angiograms in vivo as a diagnostic tool in coronary atherosclerosis.Keywords
