| 目的 探讨血液透析(HD)患者并发肺动脉高压的发生率及肺动脉高压与心输出量的关系。方法 运用超声心动图对78例HD患者并发肺动脉高压的发生率进行评估。以是否合并有肺动脉高压将研究对象分为肺动脉高压组和无肺动脉高压组,检测两组左心室射血分数、左心室容积、心输出量及心脏指数,并进行统计学分析。结果 78例HD患者并发肺动脉高压20例,发生率25.64%。20例并发肺动脉高压的患者中15例为轻度,4例为中度,1例为重度。两组间射血分数、心脏容积、心输出量及心脏指数差异均无统计学意义。心输出量与肺动脉高压无相关性。结论 HD患者并发肺动脉高压并不少见, 本研究中心输出量不是引起肺动脉压增高的原因。动-静脉内瘘及其他因素引起的心输出量的增加对肺动脉高压的影响有待进一步研究。 |

| Objective To investigate the incidence and the relation between pulmonary hypertension (PH) and cardiac output in hemodialysis (HD) patients with PH. Methods The incidence of PH was estimated with Doppler echocardiography in 78 patients receiving HD. Left ventricular ejection fraction, cardiac volume, cardiac output and cardiac index were compared between patients with or without PH. Results PH was found in 20 patients (25.64%), among them15 had mild PH, 4 had moderate PH and 1 had severe PH. There was no statistical difference of ejection fraction, cardiac volume, cardiac output and cardiac index between the two groups. PH was not related to cardiac output. Conclusion HD can lead to PH, but cardiac output can not result in PH. Further investigations about the effect of elevated cardiac output induced by internal arteriovenous fistula and other factors on PH are needed. |
