[An Analysis of Basic Clinical Data on Hemorrhagic Stroke Patients Using the Korean Hemorrhagic Stroke Registry]

Stroke is a major cause of death and disability in Korea and given its aging population, stroke incidence cases are expected to continue to increase. In particular, hemorrhagic stroke is a highly severe type of strokes with poor prognosis. Therefore, it is necessary to build the multi-center registry system to accumulate data on clinical and epidemiological characteristics of various hemorrhagic stroke patients and based on the accumulated data to do researches on it. This study made into database the clinical data on 457 hemorrhagic stroke patients of three Korean university hospitals (Regional Cardiocerebrovascular Centers) included in the Korean Hemorrhagic Stroke Registry from September 1, 2021 to July 31, 2022 and analyzed the data. The mean age of patients in the registry was 62.8 years old, with males being 51.4%. Among them, the largest proportion of hemorrhagic stroke was taken up by intracerebral hemorrhage (68.9%), followed by subarachnoid hemorrhage (26.1%) and intraventricular hemorrhage (5.0%). 61.7% of patients arrived within 3 hours of onset, and 81.4% of patients were carried to hospital by ambulance. Arriving at hospital, 49.2% of patients were under stupor or worse. The most prevalent risk factor for hemorrhagic stroke was high blood pressure (50.5%), followed by alcohol (37.6%) and smoking (24.3%). The mean rate of expired at hospital was 13.6%, with that of subarachnoid hemorrhage being the highest (18.5%). This study expects that there will be further long-term follow-up studies in the future that will contribute to creating the guidelines for hemorrhagic stroke and establishing national public health policies.
