Stroke-heart syndrome is defined as a cardiovascular complication occurring within 30 days after stroke， including acute myocardial injury， acute coronary syndrome， cardiac insufficiency， arrhythmia， etc. Recent studies indicated that autonomic dysfunction， brain-gut axis damage， and inflammation may be involved in its pathogenesis. However， its etiology and prognosis are still not well elucidated. In addition， the stroke-heart syndrome may lead to a series of long-term complications like myocardial infarction， chronic cardiac dysfunction， cerebral white matter lesions， cognitive impairment， etc.， which can affect the prognosis of patients. This article reviews the research progress on the pathogenesis， long-term complications， and early risk assessment methods of stroke cardiac syndrome， aiming to deepen the understanding of this disease and provide reference for the development of more prevention and treatment methods in the future.
