摘　　要：目的探讨不同功能状态和肺动脉压力分级的肺动脉高压(PH)患者实验室指标特征。方法对2006年1月至2011年12月该院门、急诊及住院部符合PH诊断的2 752例患者资料进行回顾性研究。根据WHO PH功能及肺动脉压力分级对患者病情程度作临床评估,观察不同功能状态和压力分级的患者血液学指标、炎症指标及血气分析的特征。结果 PH患者中最常出现的血液学异常指标为血清脑钠肽(BNP)升高(89.12%)、肝脏功能异常(75.98%)和血红蛋白(Hb)异常(58.32%)。红细胞沉降率(ESR)和高敏C-反应蛋白(hs-CRP)在PH患者中升高的比例分别为78.52%和73.59%。血清BNP升高、肝脏功能异常、Hb异常、血尿酸(UA)升高、ESR升高在不同PH功能状态及肺动脉压力患者人群中的构成比差异有统计学意义(P<0.05)。最常出现的血气分析异常是低氧血症(83.08%)。在酸碱失衡中,以呼吸性碱中毒发生率最高(24.58%)。结论 PH患者中最常出现的血液学异常指标为BNP升高、肝脏功能异常和Hb异常;而此3项指标及UA、ESR升高等实验室指标的异常,往往与PH患者病情严重程度相关,需定期随访。Objective To analyze the laboratory index characteristics of pulmonary hypertention （PH ） patients with different function states and pressure stages .Methods 2 752 patients diagnosed with PH in the outpatient department ,emergency depart-ment and inpatient department of this hospital from January 2006 to December 2011 were retrospectively analyzed .The clinical as-sessment of the disease condition was done according to the function state and pressure stage of PH recommended by WHO .The characteristics of hematological indexes ,inflammatory indicators and blood gas analysis were observed as well .Results The most common hematological abnormal indexes were the serum brain natriuretic peptide （BNP） elevation（89 .12% ） ,abnormal liver func-tion（58 .32% ） and abnormal hemoglobin（58 .32% ） .The proportion of the PH patients with the elevation of erythrocyte sedimenta-tion rate（ESR） and high-sensitivity C-reactive protein （hs-CRP） were 78 .52% and 73 .59% respectively .The constituent ratio of the BNP increase ,liver function abnormality ,abnormal hemoglobin ,elevation of UA and ESR had statistical differences among the PH patients with different function states and pressure stages （P＆lt;0 .05） .The most commonly blood gas analysis abnormality was hypoxemia（83 .08% ） .Respiratory alkalosis had the highest incidence rate in the acid-base imbalance（24 .58% ） .Conclusion The most common hematological abnormal indexes among PH patients are the elevation of serum BNP ,abnormal liver function and he-moglobin abnormality .The laboratory abnormal indexes of above 3 items and the increase of UA and ESR are always related with the severity of disease ,which should to be followed-up .
