With the evolving spectrum of cardiovascular diseases and changing characteristics of patient populations, the traditional coronary care unit can no longer meet the demands of critically ill patients. In recent years, the development of cardiac intensive care unit (CICU) has become a central focus in the field of critical cardiology. This expert consensus, initiated by the Heart Critical Care Subdivision of Zhejiang Medical Data Industry Research Association and the Cardiac Critical Care Committee of Chinese Medical Doctor Association, was jointly drafted by specialists from multiple tertiary hospitals with extensive experience in cardiac critical care. Drawing upon comprehensive reviews of international and domestic guidelines, available evidence, and clinical practice, the consensus outlines recommendations on CICU models of care, tiered management systems, ward design, equipment allocation, staffing, and training frameworks. The consensus aims to provide practical and evidence-based guidance for CICU establishment and management in China, foster standardized development nationwide, and facilitate alignment with international best practices.
