Analysis of 6 701 patients with cardiovascular diseases hospitalization

目的利用较大样本住院资料分析兰州大学第一医院心血管疾病住院患者病种的构成比,探讨本地区心血管疾病的发病情况和病种变迁规律。方法回顾性分析1995年1月-2004年12月兰州大学第一医院6701例、按国内同期标准诊断的住院心血管疾病资料,病种参考国际疾病分类(ICD9)、略加调整共分9类,按年度对心血管疾病病种和年龄进行分析。结果6701例心血管疾病住院患者中男性3049例,48.18±21.57岁,女性3652例,49.73±22.09岁,两者有显著性差异(P=0.004)。冠心病、高血压病、先天性心脏病、心律失常、风湿性心脏病、特发性心肌病、病毒性心肌炎、心脏神经症和其他的构成比分别为27.58%、25.46%、18.42%、14.13%、7.91%、2.28%、2.22%、1.28%和0.70%。50～70岁年龄段分布频率占整个年龄段的46.79%,冠心病和高血压病的住院年龄段以60～70岁占首位。10年间冠心病的住院年龄有显著性差异(P=0.016),但无明显年轻化趋势。结论心血管疾病构成比中冠心病和高血压病所占比例排1、2位,心律失常的住院患者以年均1.05%的速度递增,风湿性心脏病的住院比例且以年均0.51%的速度递减。50～70岁系心血管疾病住院的主要年龄段。

Objective To analyze the constituent ratio of 6 701 patients with cardiovascular diseases in The First Hospital of Lanzhou University from January 1995 to December 2004.Methods A retrospective review on the case date of the first Hospital of Lanzhou University,analysed the constituent ratio of 6 701 Chinese patients who cardiovascular diseases hospitalization,and these cardiovascular diseases were classified into 9 categories according to International Classification of Disease 9.Results The constituent ratio of coronary heart disease,essential hypertension,congenital heart disease,cardiac arrhythmia,rheumatic heart disease,idiopathic cardiomyopathy,viral myocarditis,cardioneurosis and other cardiac disease was 27.58%,25.46%,18.42%,4.13%,7.91%,2.28%,2.22%,1.28% and 0.70%,respectively.The frequency of distribution for portion of age between 50 and 70 years occupied 46.79% in total.The first portion of age both coronary heart disease and essential hypertension was between 60 and 70 years.Conclusion The constituent ratio of 6 701 patients with cardiovascular diseases,53.04% is coronary heart disease and essential hypertension.Hospitalization patients with cardiac arrhythmia increase gradually at a rate of 1.05% and hospitalization patients with rheumatic heart disease decrease gradually at a rate of 0.51% a year.The major of age portion of 50~70 years in hospitalization patients with cardiovascular disease.
