標題: | Apolipoproteins and Carotid Artery Atherosclerosis in an Elderly Multiethnic Population: The Northern Manhattan Stroke Study | 作者: | JENG, JIANN-SHING | 公開日期: | 2002 | 卷: | v.165 | 期: | n.2 | 起(迄)頁: | 317-25 | 來源出版物: | ATHEROSCLEROSIS | 摘要: | The association of apolipoproteins A-I and B (apo A-I and apo B) with cardiovascular disease has been studied in younger populations, but there is sparse information in the elderly. We determined whether apo A-I and apo B were associated with carotid artery atherosclerosis (CAA) in 507 stroke-free elderly community residents (mean age 70.1+/-11. 7 years, 60% women, 41% Hispanics, 30% African American, 28 % Caucasian). CAA severity was normal (no plaque or carotid stenosis) in 39%, mild (maximum plaque thickness =1.8 mm or carotid stenosis <40%) in 25%, and moderate/severe ( maximum plaque thickness >1.8 mm or carotid stenosis >/=40%) in 36%. CAA severity increased with age in all race/ethnic groups (P<0.01). CAA was similar among African Americans and Caucasians, but less in Hispanics (age adjusted OR: 0.5, CI : 0.4-0.8). apo A-I <1.2 g/l (OR: 2.0, CI: 1.0-3.3) and apo B >/=1.4 g/l (OR: 2.0, CI: 1.1-3.6) were associated with moderate- severe CAA. An apo B/apo A-I ratio >/=1 was associated with moderate- severe CAA (OR: 2.4, CI: 1.3-4.4), and the association varied by race ( Hispanics OR: 4.3, CI: 1 .8-10; non-Hispanics, OR: 1.4, CI: 0.6-3.2). Total cholesterol, triglycerides and low density lipoprotein cholesterol were not associated with moderate-severe CAA, while high density lipoprotein cholesterol was protective ( OR: 0.4, CI: 0.2-0.8). Thus, in an elderly population, apo A -I and B were determinants of moderate-severe CAA, and the degree of association varied by race/ethnicity |
