摘要 目的:研究缺氧性肺动脉高压(HPH)患者血浆C-型利钠肽(CNP)和神经肽Y(NPY)的水平变化,探讨CNP、NPY与HPH的关系,以揭示HPH的发病机制。方法:选择慢性阻塞性肺疾病(COPD)并肺动脉高压、肺心病患者30例和对照组20例,用放免法测定血浆CNP、NPY的含量,并同时测定其血氧分压和肺动脉压力。结果:(1)血浆CNP、NPY的含量在HPH组均高于对照组[HPH组为(78.20±22.31)、(209.01±42.25)pg/mL,对照组为(20.51±4.96)、(135.52±20.12)pg/mL;t=13.36,7.29;P<0.01]。(2)血浆CNP、NPY与氧分压呈负相关关系(r=-0.78,-0.67;P<0.01)。(3)血浆CNP与NPY呈正相关关系(r=0.68,P<0.01)。结论:CNP、NPY参与了HPH发生、发展的病理生理过程。在HPH中,收缩血管与舒张血管因子均升高,二者比例可能决定肺动脉高压的发生、发展。
