目的在心血管重症病房建立患者病情危重程度的客观评估系统以更好地进行近期预后判断。方法根据心血管科重症患者特异病因的风险特征及脏器衰竭发展规律,制定病情危重程度评分量表,从武汉协和医院心血管科重症病房选取具备一项特定的急性心血管重症疾病或伴有一项脏器功能严重衰竭需要生命支持的患者共320例,采用病情危重程度评分量表对其进行评估,患者评分分值分为≤12分,~18分,~24分及〉24分等4个级别,观察记录各级别患者存活并成功出院的比例,分析危重程度评分与患者近期存活率的关系,评估该量表的临床应用价值。结果入住心血管重症病房的患者随着危重程度评分值的升高,其存活率显著下降,评分≤12分、~18分、~24分及〉24患者的平均存活率分别为91.9%、75.6%、48.8%、9.4%。结论基于特异心血管病病因及脏器衰竭制定的心血管科危重程度评分较好地反映了患者的近期预后,具有明显的临床应用价值。

英文摘要：

Objective To develop an objective evaluation system for assessment of the severity of critically ill patients with cardiovascular disease in order to better evaluate the short-term prognosis of these patients.Methods A critical severity score scale was developed based on the risk characteristics of patients with severe cardiovascular disease,or developing organ failure.A total of 320 patients who had severe acute cardiovascular disease or a severe organ failure and required life support were selected from the Cardiovascular Intensive Care Unit of Wuhan Union Hospital.The disease severity was assessed by using the critical severity score scale.The patients were divided into four levels according to the score：≤12points,13-18 points,19-24 points,and 24points.The proportion of patients who survived and was discharged from hospital were recorded in all levels.The relationship between the scores and the survival rates was analyzed and the clinical value of the severity score scale was evaluated.Results The survival rate decreased significantly with the severity score increasing in the patients admitted to the Cardiovascular Intensive Care Unit.The average survival rate was 91.9%in ≤12score points group,75.6%in 13-18 points group,48.8%in 19-24 point group,and 9.4%in24points group.Conclusion The objective severity evaluation system established on the specific cause of cardiovascular disease and organ failure can predict the short-term prognosis of patients,and represent a significant clinical value.
