Old age groups have different risk profile and stroke features compared to younger groups. Our aim was to examine the risk factor profile and stroke subtype in patients older than 80 years with ischemic stroke. Data of 535 patients with ischemic stroke or transient ischemic attack (TIA) were prospectively recorded. Cardiovascular risk factors and stroke subtype in individuals aged 80 years or older were compared with patients under 80. Of 535 patients a total of 179 were over 80 years (33.5%). The mean age was 84.4 ± 4.4 years (61.8%; 111 women). The most common risk factors included hypertension (82.7%) and hyperlipidemia (40.2%). Lacunar stroke was the most frequent subtype of stroke (41.7%). When the groups were compared, we observed the following risk factors more frequently in the group older than 80: female patients ( P = <0.001), hypertension (OR = 1.62), atrial fibrillation (OR = 2.64); whereas diabetes (OR = 0.54), hyperlipidemia (OR = 0.57), smoking (OR = 0.17) and obesity (OR = 0.58) were more frequent in the group younger than 80. In the old group we found a high incidence of ischemic stroke in women. We also found a higher frequency of hypertension and atrial fibrillation. The available and future epidemiological data will provide a better knowledge about the effect of typical risk factors in old people.
