心源性卒中是由各种原因的心脏疾病导致的心脏附壁血栓脱落，且栓塞于脑动脉系统时出现的卒中，约占所有缺血性卒中的30%。目前为了寻找栓子可能来源于心脏的证据，需要大量的辅助检查。良好的血液生物学标志物对急诊医生快速判别缺血性卒中类型至关重要，然而目前这方面的研究还没有突破。脑利钠肽在心室肌和下丘脑均有分泌，可能是脑、心疾病之间相互影响的重要桥梁，但其在心源性卒中诊治方面的应用仍十分局限。文中对脑利钠肽水平与心源性卒中的研究现况进行综述，并提出了进一步的研究趋势和展望。“,”Cardiac stroke is a stroke that occurs when a heart mural thrombus falls off and embolizes in the cerebral arterial system caused by various causes of heart disease, accounting for about 30% of all ischemic strokes. At present, in order to find evidence that emboli may originate from the heart, a large number of auxiliary examinations are needed. Good blood biomarkers are essential for the rapid identification of ischemic stroke in the emergency department. However, there is no breakthrough in this area. Brain natriuretic peptide is secreted in ventricular muscle and hypothalamus. It may be an important bridge between brain and heart diseases. However, the application of brain natriuretic peptide in the diagnosis and treatment of cardiogenic stroke is still very limited. This article reviews the current research status of brain natriuretic peptide levels and cardiogenic stroke and proposes further research trends and prospects.
