摘要
肺动脉高压在先天性心脏病中很常见,有效地降低患儿肺血管阻力,能够改善其远期生存率。对肺动脉高压病理生理的研究发现,使用磷酸二酯酶5抑制剂可使肺血管舒张,降低肺血管阻力。目前磷酸二酯酶5抑制剂西地那非在国外已用于治疗肺动脉高压。多个临床试验已经证明磷酸二酯酶5抑制剂能够显著降低肺血管阻力,改善患者远期生存率和生活质量,且能较好地被患者耐受。
Pulmonary arterial hypertension is conanon in patients with congenital heart disease. An effective reduction in pulmonary vascular resistance could improve the survival rate in the future. Research in the pathophysiology of pulmonary arterial hypertension shows that phosphodiesterase 5 inhibitors result in pulmonary vasodilation, decrease vascular resistance. Sildenafil, a inhibitor of phosphediesterase 5 has been permitted to treat pulmonary arterial hypertension oversea now. Phosphediesterase 5 inhibitors are proved to reduce pulmonary vascular resistance significantly, improve the survival rate in the future and be well tolerated. This review contains the changes of bemedynamics, exercise tolerance, side effect and pharmacokinetics of phosphodiesterase 5 inhibitors.
