Multidisciplinary Collaborative Care System for Acute Myocardial Infarction Complicated With Cardiogenic Shock

Acute myocardial infarction complicated by cardiogenic shock (AMI-CS) represents the most life-threatening subtype of acute cardiovascular diseases. Current clinical management of AMI-CS in China is plagued by multiple structural challenges, including a rapidly aging patient population, inequitable distribution of medical resources, the absence of standardized care models, and poor applicability of international risk stratification tools. Owing to ethnic disparities in disease presentation and the low penetration of mechanical circulatory support (MCS) devices in China, international clinical evidence for AMI-CS diagnosis and treatment cannot be directly translated into local clinical practice. Furthermore, the lack of a standardized multidisciplinary collaborative care system has become a critical bottleneck hindering the reduction of AMI-CS mortality. To address these unmet clinical needs, this study aims to develop a tailored multidisciplinary collaborative care system adapted to China's healthcare landscape and to evaluate its clinical efficacy and safety via a prospective multicenter registry study. The study will establish a tiered collaborative network encompassing healthcare institutions of all levels and formulate standardized clinical pathways and risk stratification strategies for AMI-CS. A total of at least 1,000 AMI-CS patients will be enrolled in the study, with systematic collection of their clinical characteristics, multidisciplinary interventions, MCS utilization, and prognostic outcomes to build a high-quality real-world database. Based on the registry data, a China-specific risk stratification model for AMI-CS will be developed by integrating clinical metrics, biomarkers, and imaging features. This study will assess the benefits and risks of MCS devices used alone or in combination, and evaluate the implementation effectiveness of the multidisciplinary collaborative care system by comparing core outcomes-including 30/180-day all-cause mortality, s
