我们感谢Tanus-Santos博士对我们研究的兴趣。1 Muniz等人2的研究发现,内源性一氧化氮(NO)水平最低的勃起功能障碍患者对磷酸二酯酶-5(PDE 5)抑制剂西地那非的反应最好。我们认为肺动脉高压(PAH)患者也存在类似情况。我们发现我们研究中的PAH患者的NO产生受损,这表明这些患者是利用伐地那非治疗获益的最佳候选人。这可能是因为伐地那非是一种相对选择性的肺血管扩张剂,...
We thank Dr. Tanus-Santos for his interest in our study.1 The study by Muniz et al .2 found that erectile dysfunction patients with the lowest levels of endogenous nitric oxide (NO) have the best responses to the phosphodiesterase-5 (PDE5) inhibitor sildenafil. We believe an equivalent situation exists in patients with pulmonary arterial hypertension (PAH). We found impaired NO production in the patients with PAH included in our study, suggesting that these patients are the best candidates to take advantage of the benefits of vardenafil treatment. This may be because vardenafil is a relatively selective pulmonary vasodilator, which …
