评价动态血压与动态心电图同步监测高血压无症状心肌缺血患者的应用价值

Value of simultaneous ambulatory blood pressure and electrocardiography monitoring in hypertensive patients with asymptomatic myocardial ischemia

目的对动态血压与动态心电图同步监测在高血压无症状心肌缺血(SMI)患者中的应用价值进行分析和评价。方法选取我院2014年1月-2016年6月收治的50例高血压患者,按照是否伴有左室肥厚将患者分为观察组(伴有左室肥厚)和对照组(无左室肥厚),两组患者均分别接受动态血压与动态心电图同步监测,比较监测结果。结果观察组患者无症状心肌缺血发生率为66.70%,显著高于对照组患者的25.00%,比较差异具有统计学意义(P<0.05);两组患者昼夜收缩压,舒张压之间的比较差异不显著(P>0.05),但观察组患者昼夜心率均高于无左室肥厚对照组患者,同时有SMI的患者昼夜心率均高于无SMI的患者,比较差异显著(P<0.05)。结论动态血压与动态心电图同步监测在高血压无症状心肌缺血患者中的应用价值显著,可有效监测患者心率变化,提高无症状心肌缺血患者检出率。

Objective To investigate the value of simultaneous ambulatory blood pressure and electrocardiography monitoring in hypertensive patients with asymptomatic myocardial ischemia （SMI）. Methods A total of 50 hypertensive patients who were admitted to our hospital from January 2014 to June 2016 were enrolled, and according to the presence or absence of left ventricular hypertrophy, the patients were divided into observation group （with left ventricular hypertrophy） and control group （without left ventricular hypertrophy）. The patients in both groups were given simultaneous ambulatory blood pressure and electrocardiography monitoring, and the monitoring results were compared between the two groups. Results The observation group had a significantly higher incidence rate of SMI than the control group （66.70% vs 25.00%, P〈O.05）. There were no significant differences in diurnal systolic pressure and diastolic pressure between the two groups （P〉0.05）, but the observation group had a significantly higher diurnal heart rate than the control group, and the patients with SMI also had a significantly higher diurnal heart rate than those without SMI （P〈0.05）. Conclusion Simultaneous ambulatory blood pressure and electrocardiography monitoring has a significant value in hypertensive patients with SMI and can effectively monitor the change in heart rate and improve the detection rate of patients with SMI.
