title: A comparison of coronary and internal mammary arteries and implications of the results in the etiology of arteriosclerosis.
abstract: Comparison was made between the intimal thickening of the anterior descending branch of the left coronary artery and the internal mammary artery in 352 necropsy examinations. The coronary arteries showed severe intimal thickening, progressing in severity throughout life, whereas the internal mammary showed no more than slight changes at any age. These observations, together with the variation in severity of the changes in different portions of the same vessel, and the freedom from this disease of the smaller arteries throughout the body, strongly suggest that a local or anatomic factor is the dominant influence in coronary artery disease.
