[Pathogenesis of carotid cerebrovascular accidents in an elderly cohort. Study of 62 patients more than 75 years old].
We have studied the cause of stroke in 62 patients aged over 75 years who suffered transient ischemic attacks (TIA) and minor stroke, compared to a control group of younger (age 45-74 years) patients with stroke of the same severity. Patients aged over 75 years had a higher incidence of events of undetermined origin, cardiac embolism, or multiple etiologies. This contrasted with a low prevalence of ischemic events secondary to stenosing carotid atheromatosis, and (to a lesser extent) hypertensive arteriolopathy, which predominated in the control group. The differences may be explained in part by a different distribution of risk factors in the older and younger patients, the latter being at higher risk for earlier vascular death.
