Autopsy studies of atherosclerosis of the aorta and the coronary arteries were carried out in 3134 subjects with essential hypertension. A comparison was made with low, average, and high atherosclerosis groups. Essential hypertension was found to accelerate the development of all types of aortic lesion, except fatty streak, as compared with the standardized average atherosclerosis group, and to accelerate the development of fibrous plaque but not complicated and calcified lesions as compared with the high atherosclerosis group. The extent of fibrous plaque in the coronary arteries was greater in the essential hypertension group than in the low and standardized average atherosclerosis groups but did not differ from that in the high atherosclerosis group. The extent of complicated and calcified lesions and the prevalence of coronary stenosis were higher in the high atherosclerosis group than in cases of hypertension. Geographical differences in atherosclerosis among hypertensives in different towns reflected the findings for the whole material. Symptomatic hypertension was found to accelerate aortic atherosclerosis at least to the same extent as essential hypertension. It was conductive to coronary atherosclerosis but not to the same extent as essential hypertension. Coronary stenosis and various manifestations of coronary heart disease were rare in symptomatic hypertension. |
