【摘要】：目的:應用斑點追蹤成像技術(STI)中的心肌分層應變探討其在評價尿毒癥患者左室圓周收縮功能方面的價值。方法:選取78例確診為尿毒癥并行維持性血液透析的患者,根據左室構型情況分為左室構型正常組(LVN組,42例)和左室肥厚組(LVH組,36例),選擇38例健康人作為對照組。先行常規(guī)數據測量,接著應用STI獲取所有患者胸骨旁左室二尖瓣口、乳頭肌及心尖水平心內膜下心肌、中層心肌和心外膜下心肌收縮期圓周應變(CS)。結果:與對照組和LVN組比較,LVH組IVSTd、LVPWTd、LAESd、E/A顯著升高(均P0.05)。LVN組、LVH組和對照組的CS均存在如下規(guī)律:即心內膜下心肌CS最大,心外膜下心肌CS最小;與對照組比較,LVN組3層心肌CS降低均無統(tǒng)計學意義;與對照組及LVN組比較,LVH組二尖瓣口及乳頭肌水平心內膜下和中層心肌CS均顯著降低(均P0.05)。結論:心肌分層應變技術可以定量逐層評價尿毒癥患者左室CS,為準確判斷其心肌受累情況提供一種新的檢查方法。
[Abstract]:Objective: to investigate the value of myocardial delamination strain in dot-tracing imaging (STI) in evaluating left ventricular peripheral systolic function in uremic patients. Methods: 78 patients with uremia and maintenance hemodialysis were selected. According to the left ventricular conformation, the patients were divided into two groups: left ventricular normal group (n = 42) and left ventricular hypertrophy group (n = 36). 38 healthy persons were selected as control group. Routine data were measured first, and then left ventricular mitral orifice was obtained by STI. Papillary muscle and apical level subendocardial myocardium, Results: compared with the control group and the LVN group, the systolic circumferential strain of the middle and epicardial myocardium was significantly increased. Results: compared with the control group and the LVN group, the CS of the IVSTD group was significantly higher than that of the control group. (the CS of both the P0.05).LVN group and the control group were as follows: the subendocardial myocardial CS was the largest. Compared with the control group, there was no significant difference in CS between LVN group and LVN group. Compared with the control group and the LVN group, the CS of the subendocardial and middle myocardium in the mitral orifice and papillary muscle were significantly decreased (all P 0.05). Conclusion: myocardial stratification strain technique can quantitatively evaluate left ventricular CSS in uremic patients, which is an accurate judgment. A new method for detecting myocardial involvement is provided.
