目的 应用斑点追踪显像定量评价阻塞性睡眠呼吸暂停综合征患者的左心房功能,并进行对比研究。方法 OSAS患者60例,根据睡眠呼吸暂停低通气指数(AHI)分为3组,轻度组,中度组,重度组,每组20人;另选择20名健康正常人作为正常对照组。采用二维斑点追踪成像技术测量各组左心房相关应变参数:收缩期应变(Ss),舒张早期应变(Se),舒张晚期应变(Sa),左心房收缩期应变率(SRs),左心房舒张早期应变率(SRe),左心房舒张晚期应变率(SRa),分析并比较各组间参数的差异性。结果 随着疾病严重程度的增加Ss、SRs、Se、SRe呈逐渐减低的趋势,而Sa、SRa先升高后减低,差异有统计学意义(P<0.05)。结论 应用斑点追踪成像技术可在OSAS患者发生左心房重构前检测出心房功能的变化。
Objective The left atrial function of patients with obstructive sleep apnea syndrome was quantitatively evaluated by speckle tracing imaging and compared. Methods Sixty patients with OSAS were divided into three groups according to the sleep apnea hypopnea index(AHI),including the mild group, the moderate group and the severe group, with 20 patients in each group. Another 20 healthy people were selected as the normal control group. Left atrial correlation strain parameters:systolic strain(Ss), early diastolic strain(Se), late diastolic strain(Sa), left atrial systolic strain rate(SRs), early diastolic strain rate(SRe), left atrium left atrium late diastolic strain rate(SRa) were measured by two dimensional speckle tracking imaging technology, and the differences of parameters between groups were compared. Results With the increase of disease severity, Ss, SRs, Se and SRe showed a trend of gradual decrease, while Sa and SRa increased first and then decreased, and the difference was statistically significant(P<0.05). Conclusion Changes in atrial function may be detected in OSAS patients prior to left atrial remodeling using speckle tracking imaging.
