摘要
目的:观察夜间非勺型心率与不同类型的冠心病的关系。方法:220例经冠状动脉造影证实的冠心病患者,分为急性心肌梗死(AMI)组69例、不稳定型心绞痛(UAP)组71例,稳定型心绞痛(SAP)组80例。72例非冠心病者作为对照组。应用动态血压记录各组患者入院后第14天的24h心率,分析夜间非勺型心率百分比。结果:AMI组、UAP组、SAP组和对照组夜间非勺型心率百分比分别为46.25%、35.36%、20.25%和18.32%。AMI组比UAP组大(P<0.05),且均大于SAP组和对照组(均P<0.05)。结论:冠状动脉病变越严重,夜间非勺型心率比例就越大。
Objective： To study the relationship between nocturnal non-dipping heart rate and coronary heart disease. Methods： The 220 cases with coronary heart disease were divided into three groups： acute myocardial infarction （AMI） group （n=69）, unstable angina peetoris （UAP） group （n=71）, stable angina （SAP） group （n=80）. There were additional 72 cases of non-coronary heart disease in control group. 24 hours heart rate of patients was recorded by ambulatory blood pressure monitoring on the 14th day of admission. Results：The percent- age of nocturnal non-dipping heart rate in AMI, UAP, SAP, control groups were 46.25%, 35.36%, 20.25%, 18.32%, respectively, which was significantly higher in AMI group and UAP group than in SAP group and con- trol group （all P〈0.05）. Conclusion： The greater percentage of nocturnal non-dipping heart rate is correlated with severer coronary artery disease.
