Association between physical activity and peripheral artery disease and carotid artery stenosis in a self-referred population of 3 million adults.

ABSTRACT: Although the relationship between physical activity and coronary heart disease is well characterized, a paucity of data exists on physical activity and vascular disease in other arterial territories. This study examined the prevalence of peripheral artery disease (PAD) and carotid artery stenosis (CAS) in association with physical activity.The association between physical activity and vascular disease was examined in >3 million self-referred US participants in the United States from 2003 to 2008 who completed a medical and lifestyle questionnaire in the Life Line screening program. All subjects were evaluated by screening ankle brachial indices <0.90 for PAD and ultrasound imaging for CAS >50%. Multivariable logistic regression modeling was used to estimate odds of disease. Among 3 250 350 subjects, 63% of the population engaged in some leisure time vigorous physical activity. After adjustment for age, sex, race/ethnicity, hypertension, hypercholesterolemia, smoking status, diabetes mellitus, body mass index, and family history of cardiovascular disease, subjects who reported any physical activity had a significantly lower odds of PAD (odds ratio, 0.64; 95% confidence interval, 0.63-0.65) and CAS (odds ratio, 0.80; 95% confidence interval, 0.79-0.81). The association between physical activity with PAD and CAS was robust when stratified by sex, race, and age categories. Physical activity intensity frequency was associated with lower PAD and CAS in a graded manner (P trend <0.0001 for both). Findings seemed unaffected by confounding by comorbidity or indication.In a large population-based study, higher levels of physical activity were independently associated with lower odds of vascular disease in the lower extremities and carotid arteries.

Project description:Patients with contralateral carotid occlusion (CCO) have been excluded from randomized clinical trials because of a deemed high risk for adverse neurologic outcomes with carotid endarterectomy (CEA). Evidence for this rationale is limited and conflicting. Therefore, we aimed to compare outcomes after CEA between patients with and without CCO and varying degrees of contralateral carotid stenosis (CCS).We identified patients undergoing CEA from 2003 to 2015 in the Vascular Study Group of New England (VSGNE) registry. Patients were stratified by preoperative symptom status and presence of CCO. Multivariable analysis was used to account for differences in demographics and comorbidities. Our primary outcome was 30-day stroke/death risk.Of 15,487 patients we identified who underwent CEA, 10,377 (67%) were asymptomatic. CCO was present in 914 patients, of whom 681 (75%) were asymptomatic. Overall, the 30-day stroke/death was 2.0% for symptomatic patients (CCO: 2.6%) and 1.1% for asymptomatic patients (CCO: 2.3%). After adjustment, including symptom status, CCO was associated with higher 30-day stroke/death (odds ratio [OR], 2.1; 95% confidence interval [CI], 1.4-3.3; P = .001), any in-hospital stroke (OR, 2.8; 95% CI, 1.7-4.6; P < .001), in-hospital ipsilateral stroke (OR, 2.2; 95% CI, 1.2-4.0; P = .02), in-hospital contralateral stroke (OR, 5.1; 95% CI, 2.2-11.4; P < .001), and prolonged length of stay (OR, 1.6; 95% CI, 1.3-1.9; P < .001). CCS of 80% to 99% was only associated with a prolonged length of stay (OR, 1.3; 95% CI, 1.1-1.6; P = .01), not with in-hospital stroke. Neither CCO nor CCS was associated with 30-day mortality.Although CCO increases the risk of 30-day stroke/death, in-hospital strokes, and prolonged length of stay after CEA, the 30-day stroke/death rates in symptomatic and asymptomatic patients with CCO remain within the recommended thresholds set by the 14 societies' guideline document. Thus, CCO should not qualify as a high-risk criterion for CEA. Moreover, there is no evidence that patients with CCO have lower stroke/death rates after carotid artery stenting than after CEA. We believe that CEA remains a valid and safe option for patients with CCO and that CCO should not be applied as a criterion to promote carotid artery stenting per se.
