Modern studies have progressively uncovered the intricate interplay between the brain and the heart, with cerebral injury influencing cardiac dysfunction, leading to a causative relationship. post-stroke cardiac changes, a common clinical disease caused by brain injury resulting in cardiac dysfunction, often presents medical challenges within the first few days after a stroke. Acute brain injuries can trigger heart failure even in the absence of primary heart disease, leading to potential long-term cardiac complications such as myocardial infarction, arrhythmias, and heart failure. These complications have become the second leading cause of death after stroke, with approximately 2–6 % of stroke patients dying from cardiac causes within the first three months after an ischemic stroke. The pathophysiology of post-stroke cardiac changes is still under investigation, and there is no standardized clinical treatment or universally accepted therapeutic approach. This paper aims to review the current global research status and trends in post-stroke cardiac changes.</div></div><div><h3>Methods</h3><div>Articles on post-stroke cardiac changes published from 1990 to 2025 were identified using the Web of Science Core Collection database.
