Research Progress on Risk Factors of In-Hospital Cardiac Arrest in Adults

院内心脏骤停(in-hospital cardiac arrest, IHCA)是可能威胁任何住院患者生命安全的紧急事件。随着老龄化社会的到来，IHCA发生率及致死率、致残率逐年升高，且年龄越大预后越差。早期发现IHCA的独立危险因素是降低其发生率、提高救治成功率的关键环节。有关IHCA的研究数据却十分有限，IHCA的危险因素尚不完全清楚。本文拟就当前研究证据较多的成人IHCA危险因素做一综述，以期为临床防治IHCA和开展相关研究提供参考。In-hospital cardiac arrest (IHCA) is an emergency that can threaten the life of any hospitalized patient. With the advent of the aging society, the incidence, mortality and disability of IHCA increase year by year, and the older the age, the worse the prognosis. Early detection of independent risk factors of IHCA is the key to reducing its incidence and improving the success rate of treatment. Research data on IHCA are very limited, and the risk factors for IHCA are not fully understood. In this paper, the risk factors of IHCA in adults with more research evidence are reviewed in order to provide reference for clinical prevention and treatment of IHCA and related research.
