斑点追踪技术评价OSAHS 合并COPD 患者右心功能

Evaluation of right ventricular function in patients with OSAHS complicated with COPD by speckle tracking imaging

摘要:

目的 分析二维斑点追踪技术在评价阻塞性睡眠呼吸暂停低通气综合征（OSAHS）合并慢性阻塞性肺疾病（COPD）患者右心功能中的应用价值。方法 将锦州医科大学附属第一医院2015 年8 月-2016年10 月期间收治的43 例OSAHS 患者设为对照组，将同期收治的40 例OSAHS 合并COPD 患者设为观察组，均对两组患者实施常规超声心动图检查和脉冲组织多普勒超声检查，应用二维斑点追踪技术测量两组患者右心室游离壁不同段心肌应变率参数。结果 两组患者常规超声心动图检查结果和脉冲组织多普勒超声检查结果显示有部分指标比较差异有统计学意义（P <0.05）。二维斑点追踪技术分析结果显示观察组游离壁中间段心肌应变率参数、游离壁心尖段心肌应变率参数、游离壁基底段心肌应变率参数与对照组比较差异均有统计学意义（P <0.05）。结论 二维斑点追踪能够很好地评价患者右心功能，且OSAHS 合并COPD 患者的右心损害比单独OSAHS 患者更为严重。

Abstract:

Objective To analyze the value of right ventricular function in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) complicated with chronic obstructive pulmonary disease (COPD) by speckle tracking imaging. Methods Forty-three cases of patients with OSAHS treated in our hospital from August 2015 to October 2016 were selected as control group, and 40 cases of patients with OSAHS complicated with COPD were selected as observation group. They received conventional echocardiography and pulsed tissue Doppler imaging,and their strain rate parameters of different segments of free wall of right ventricle were tested with speckle tracking imaging. Results There were significant differences in partial results of conventional echocardiography and pulsed tissue Doppler imaging between the two groups (P < 0.05). There were significant differences in the parameters of myocardial strain rate in the middle segment of free wall, myocardial strain rate parameters of apical segment of free wall and myocardial strain rate parameters of basal segment of free wall under speckle tracking imaging between the two groups (P < 0.05). Conclusions Speckle tracking imaging is great in evaluation of right ventricular function,and the right heart damage in patients with OSAHS complicated with COPD is more severe than patients only with OSAHS.
