摘要
目的观察维持性血液透析(MHD)患者肺动脉高压(PH)的发生情况,探讨其相关影响因素。方法选取行MHD的终末期肾脏病患者100例,按是否发生PH分为PH组(41例)、无PH组(59例),比较两组年龄、收缩压(SBP)、舒张压(DBP)、血管通路方式(动静脉内瘘、中心静脉导管)、透析充分性指标(KT/V)及血浆白蛋白(ALB)、血红蛋白(Hb)、血钙(Ca)、血磷(P)、甲状旁腺素(PTH)等生化指标,并对相关因素进行Logistic多元回归分析。结果PH组肺动脉收缩压(PASP)为(46.72士9.26)mmHlg(1mmHg=0.133kPa),无PH组PASP为(32.06±6.14)mmHg,两组比较差异有统计学意义(P〈0.01)0PH组中动静脉内瘘占95.1%(39,41)、Hb(78.27±4.53)g/L、P1H(863.16±146.91)ng/L、右室横径(32.43±4.32)mm、右房横径(38.67±7.13)mm、右房长径(57.23±7.26)mm、左室射血分数(56.38±11.43)%,无PH组中分别为79.7%(47/59)、(82.67±5.32)g/L、(725.68±137.14)ng/L、(21.64±3.65)mm、(34.17±6.28)mm、(46.18±6.20)mm、(64.37±6.83)%,两组比较差异有统计学意义(P〈0.05或〈0.01)。Logistic多元回归分析结果显示,PTH、Hb、右房横径、左室射血分数、血管通路方式是PH发生的主要相关因素。结论血PTH、Hb、右房横径、左室射血分数、血管通路方式是MHD患者PH发生的主要相关因素,通过对上述因素进行纠正有助于PH的早期防治。
Objective To observe the occurrence and related factors of pulmonary hypertension (PH) in maintenance hemodialysis (MHD) patients. Methods One hundred MHD patients were divided into PH group (41 cases) and non-PH group (59 cases) according to the pulmonary artery pressure measured by cardiac ultrasound. The age, systolic blood pressure (SBP), diastolic blood pressure (DBP), vascular access way (arteriovenous fistula, central venous catheter), dialysis adequacy index (KT/V) andalbumin (ALB), hemoglobin (Hb), calcium (Ca), phosphorus (P), parathyroid hormone (PTH)was compared between two groups, and related factors were analyzed by Logistic regression analysis. Results Pulmonary artery systolic pressure (PASP) of PH group and non-PH group was (46.72 ± 9.26) mm Hg ( 1 mm Hg = 0.133 kPa) and (32.06 ± 6.14) mm Hg, and the difference between two groups was significant(P〈 0.01 ). The arteriovenous fistula rate accounts for 95.1% (39/41)in PH group, and Hb was (78.27 ± 4.53) g/L, PTH was (863.16 ± 146.91) ng/L, right ventricular cross diameter was (32.43 ±4.32) mm, right atrial cross diameter was (38.67 ± 7.13 ) mm, right atrial length diameter was (57.23 ±7.26) mm and left ventricular ejection fraction(LVEF) was(56.38 ±11.43)%, while 79.7%(47/59), (82.67 ±5.32) g/L,(725.68± 137.14) ng/L, (21.64 ±3.65 ) mm, (34.17 ±6.28) mm, (46.18± 6.20) mm, (64.37± 6.83 )% in non-PH group,the differences were statistically significant between two groups (P 〈0.05 or 〈0.01). Multivariate Logistic regression analysis showed that serum PTH, Hb, right atrial cross diameter, LVEF, vascular access way were related factors of PH. Conclusion The serum PTH, Hb, right atrial cross diameter, LVEF, vascular access way are related factors of PH, and the PH may be early prevented and treated by correcting these related factors.
