Five Year Outcomes in Men Screened for Carotid Artery Stenosis at 65 Years of Age: A Population Based Cohort Study - European Journal of Vascular and Endovascular Surgery

Among men participating in carotid screening at age 65, 3,057 were re-screened at age 70. In those with normal carotids (n = 2,318), 23 (1.0%) progressed to a moderate stenosis, and four (0.2%) to a symptomatic severe stenosis. Among those with plaque (n = 696), 25 (3.6%) progressed to moderate stenosis, and eight (1.1%) to severe stenosis, of whom four (0.6%) had symptoms. Of 31 men with 50–79% stenosis, four (12.9%) had progressed to a severe stenosis, of whom two (6.5%) developed symptoms. Five of twelve subjects (42%) with 80–99% stenosis developed symptoms. Disease regression was present among 289/692 plaque (41.7%) and 16/33 stenosis (48.4%). In multivariable analysis, smoking, coronary artery disease and hypercholesterolemia were associated with disease progression. The proportions of antiplatelet, statin, and antihypertensive treatment in the population at age 70 were 22%, 29%, and 55%, respectively.
