目的:探讨高原肺动脉高压及可疑高原肺动脉高压者心脏Tei指数。方法:应用多普勒超声心动图对临床确诊高原肺动脉高压及可疑肺动脉高压者行心脏Tei指数测定,并与正常组对照。结果:高原肺动脉高压者右心Tei指数为0.50±0.05、可疑肺动脉高压者右心Tei指数为0.44±0.05,较正常组(右心Tei指数为0.29±0.04)增高。结论:临床可疑肺动脉高压者右心Tei指数增高。
Objective: To investigate the Tei index of heart in patients with plateau pulmonary hypertension and suspicious high altitude pulmonary hypertension. Methods: Doppler echocardiography was used to measure the cardiac Tei index in patients with clinically diagnosed high altitude pulmonary hypertension and suspected pulmonary hypertension, and compared with the normal group. Results: The Tei index of right heart in high altitude pulmonary hypertension was 0.50 ± 0.05, the right heart Tei index of suspected pulmonary hypertension was 0.44 ± 0.05, which was higher than that of normal group (right heart Tei index was 0.29 ± 0.04). Conclusion: The Tei index of right heart in patients with suspected pulmonary hypertension is increased.
