Patients with vascular disease risk factors will be identified by physicians in Family Practice or Internal Medicine, through chart review, or through advertisements. Those responding to advertisements or who have been referred by a physician will be invited to complete a screening phone call or to complete an on-line screening measure. Potentially eligible patients who were identified through chart review will first be sent a letter. This letter will be followed, at least one week later, by a phone call to assess for interest in the study and to provide information about the screening.
