Cardio-cerebral infarction: a narrative review of pathophysiology, treatment challenges, and prognostic implications.

Abstract

Cardio-cerebral infarction (CCI) is a rare clinical syndrome characterized by the simultaneous or sequential occurrence of acute myocardial infarction (AMI) and acute ischemic stroke (AIS). Despite its complex pathogenesis and more severe prognosis compared to isolated AMI or AIS, no consensus has been established regarding its definition, classification, epidemiology, treatment protocols, or prognostic management. Current research is largely confined to case reports or small case series, and there are no unified diagnostic or treatment guidelines, nor any expert consensus. Consequently, clinicians often rely on single-disease guidelines for AMI or AIS, or personal experience, when managing CCI cases. This approach complicates treatment decisions and may result in missed opportunities for optimal interventions, thereby adversely affecting long-term patient outcomes. This narrative review aimed to systematically summarize the definition, classification, epidemiological features, pathogenesis and therapeutic strategies, and prognostic aspects of CCI while thoroughly examining the progress and limitations of existing studies to guide future research and clinical practice. By offering a detailed analysis of reperfusion strategies, antiplatelet therapy, and anticoagulation in CCI patients, this review highlights the safety and efficacy differences among current treatments and explores methods for optimizing individualized management to improve clinical outcomes. Furthermore, this article aimed to enhance clinicians' understanding of CCI, provide evidence-based recommendations for patient care, and outline directions for future research. Ultimately, by refining diagnostic and therapeutic strategies, we aimed to reduce CCI-related mortality and improve long-term prognoses for affected patients.
