The incidence of stroke has been declining in Finland, as well as in Europe. However, it is unclear whether the incidence of transient ischemic attack (TIA) is also decreasing. In fact, the TIA incidence in the Finnish population has never been reported. Therefore, here we investigated the incidence of TIA in the Eastern Finnish population in 2017.
All patients with suspected TIA, from a defined catchment area, were referred to a neurological emergency unit at Kuopio University Hospital (KUH) in the Northern Savonia region of Eastern Finland, which had a population of 246,653 in 2017. The original study population comprised TIA patients diagnosed based on the WHO TIA criteria in 2017. Incidence rates were calculated by dividing the number of TIA cases by the number of people in different age groups.
Among 432 patients with a suspected TIA referred to the neurological emergency unit at Kuopio University Hospital in 2017, 293 were living in Northern Savonia and were ultimately diagnosed with TIA after neurological examinations. The number of first-ever TIAs was 211. The crude incidence of all TIA was 122/100,000 inhabitants, and of first-ever TIA was 86/100,000. The age-standardized incidence (European population 2010) of the first-ever TIA was calculated to be 64/100,000. The mean age of first-ever TIA patients was 70 years: 72 years for women versus 68 years for men.
We found a high incidence of TIA in Eastern Finland.
中风在芬兰乃至整个欧洲的发病率都在下降。然而，目前尚不清楚短暂性脑缺血发作（TIA）的发病率是否也在下降。事实上，芬兰人群的 TIA 发病率从未有过报道。因此，我们在此研究了 2017 年芬兰东部人群的 TIA 发病率。
所有疑似 TIA 的患者，来自一个确定的研究区域，都被转至芬兰北萨沃尼亚地区的于韦斯屈莱大学医院（KUH）的神经科急诊室。2017 年，该院服务人群为 246653 人。原始研究人群包括根据世界卫生组织（WHO）TIA 标准在 2017 年确诊的 TIA 患者。发病率通过 TIA 病例数除以不同年龄组人数计算得出。
2017 年，有 432 名疑似 TIA 的患者被转诊至于韦斯屈莱大学医院的神经科急诊室，其中 293 人居住在北萨沃尼亚，经过神经学检查后最终被诊断为 TIA。新发 TIA 患者有 211 人。所有 TIA 的粗发病率为 122/100000 居民，新发 TIA 的发病率为 86/100000。按照欧洲 2010 年人口标准，新发 TIA 的发病率计算值为 64/100000。新发 TIA 患者的平均年龄为 70 岁：女性为 72 岁，男性为 68 岁。
我们发现芬兰东部 TIA 的发病率很高。
