Atherosclerosis in coronary arteries and aorta among Greenlanders: an autopsy study

In a cross-sectional autopsy study of 107 Inuit in Greenland, the extent of arterial surface involvement with atherosclerosis was evaluated in the presence of known or estimated environmental risk factors for coronary heart disease (CHD): age, gender, obesity, serum lipids, smoking, and hypertension. Mean, median, and range values for all of the risk factor variables and for the extent of atherosclerosis in the thoracic aorta, abdominal aorta, right coronary artery, and left anterior descending coronary artery are reported by age strata, along with the results of covariant analysis of the dependence of the extent of atherosclerosis upon the risk factors. No significant differences between females and males were found in either the risk factors or prevalence and extent of atherosclerosis in the aorta and in the coronary arteries. It appears that the extent of advanced atherosclerotic lesions in Greenlanders appears to be the same as that previously reported in a similar study in Alaska Natives.
