风湿性心瓣膜病患者心功能量化的初步评估

Clinical evaluation of cardiac function in patients with rheumatic heart disease

摘要: 目的:探讨风湿性二尖瓣狭窄患者术前心功能储备的评估方法。方法: 随机抽取2011年1月～12月100名风湿性二尖瓣狭窄的住院患者(患者组,n=100)和100名无心血管病史的同期在院陪护的患者家属(正常对照组,n=100)，采用心音监测仪分别于静息状态和完成规定运动量后即刻采集心音，进行心率、D/S 比值以及S1/ S2比值的对照研究。结果：患者组100名风心病患者静息状态下心率、D/S比值和运动后即刻S1/S2比值与正常对照组存在着显著的差异(均P<005)。结论：心音监测法有可能为临床心功能储备提供一种量化的标准。

Abstract: AIM:To explore a novel method for evaluating cardiac function in patients with rheumatic heart disease. METHODS: Heart sound signals were sampled randomly from 100 inpatients with rheumatic heart disease in our hospital from January to November 2011 (experimental group) and 100 relatives of patients without history of angiocardiopathy (control group). Heart rate, D/S ratio and S1/S2 ratio in the two groups were analyzed and compared. RESULTS: The heart rate, D/S ratio and S1/S2 ratio in experiment group were significantly different from those in the control group. CONCLUSION: Patients with rheumatic heart disease have lower levels of cardiac reserve. Monitoring heart sound signals is a new quantitative evaluation to assess patients’ preoperative cardiac reserve and operative tolerance.
