Recurrent Ischemic Stroke Found

A study by Professor Wang Yongjun and Dr. Zhang Changqing of the Center of Neurology, Beijing Tiantan Hospital, Capital Medical University, and the National Center for Neurological Diseases Clinical Medicine found that the degree of stenosis of responsible cerebral arteries is not less than 70% and repeated within 3 months before stroke. Ischemic cerebral ischemic attack (TIA) is a risk factor for the recurrence of ischemic cerebrovascular disease; the embolism caused by responsible cerebral artery stenosis or hypoperfusion of the distal brain tissue of the blood supply artery may be a recurrent episode of TIA and ischemic The cause of stroke recurrence. Experts believe that it is necessary to perform neuroimaging and timely and effective treatment for high-risk relapse patients. Related research papers were published in the Chinese Journal of Stroke.

The recurrence rate of patients with ischemic stroke is high in China. Currently, ESSEN stroke risk scales, improved ESSEN scales, and stroke prognosis scales are commonly used to predict ischemic stroke. However, these scales do not take into account the imaging features of the newly developed infarcts. Although the 90-day Stroke Recurrence Predictive Scale used the imaging features of the new infarcts as a predictor of stroke recurrence, it did not use responsible cerebral artery stenosis as a predictor. This is a lack of analysis of risk factors for recurrence in non-cardiogenic ischemic stroke patients.

The study included 1978 adult non-cardiogenic ischemic stroke and TIA patients. The demographic information, vascular risk factors, and main symptoms and signs at the time of onset were collected to evaluate the results of the patient's cranial magnetic resonance imaging, including the infarct Location, number, distribution of acute infarcts, and etiological classification of acute stenosis and ischemic stroke in responsible and responsible arteries; follow-up of patients with ischemic stroke or recurrent TIA within 1 year; analysis of ischemic stroke Risk factors for patient recurrence.

The results showed that the recurrence rate of ischemic cerebrovascular disease within one year was 4.8%. History of coronary atherosclerotic heart disease, history of ischemic stroke, repeated TIA within 3 months before onset of ischemic stroke, degree of cerebral arterial stenosis not less than 70%, and posterior circulation ischemic stroke, within 1 year Risk factors for recurrence. Patients with ischemic stroke with a history of coronary atherosclerotic heart disease have a higher risk of recurrence. The recurrence rate of patients with posterior circulation stroke symptoms or signs such as dizziness, diplopia, and visual field defects was higher at the time of admission. The risk of recurrence of stroke patients within one year was 1.9 times higher than that of patients with precirculation.

Wang Yongjun believes that the assessment of brain tissue and cerebrovascular imaging as soon as possible in patients with post-stroke stroke and repeated TIA episodes and targeted treatment will help reduce the risk of recurrent ischemic cerebrovascular disease.
