肺高壓
肺高壓(pulmonary hypertension,PH,PHTN)或肺動脈高壓,是肺動脈壓力持續性超過正常值的病理狀態。一般定義靜息下,肺動脈收縮壓超過30mmHg或舒張壓超過15mmHg,或是肺動脈均壓(mPAP)超過20mmHg,即為肺動脈高壓[1]。肺動脈高壓可引起肺內血流動力學改變和右心功能障礙。

肺高壓會造成疲勞、勞力性呼吸困難、胸部不適、頭暈、昏厥、下肢水腫,肺高壓患者會因為心臟負荷增加令運動能力急速下降,以及發生其他症狀,可引致心臟衰竭導致病患死亡[2]。此症於1891年由恩斯特·馮·倫伯格首次描述[3]。根據最新的分類,肺高壓共有六種形式[4]。
症狀及徵象
較罕見的症狀包含乾咳、運動時暈眩和嘔吐[6]。部分患者有咳血的現象,特別是肺高壓的某些亞型,如遺傳性肺動脈高壓、艾森門格症侯群,和慢性栓塞型肺動脈高壓等[8]。肺靜脈高壓的典型症狀為臥姿時呼吸困難(端坐呼吸及陣發性夜間呼吸困難),肺動脈高壓則無此現象[9]。
其他典型症狀包含較強的第二心音。另外右心室肥大也會造成右心室產生第三心音,以及胸骨旁起伏。右心衰竭導致的全身性鬱血則可能合併有頸靜脈屈張、腹水,以及肝頸動脈回流[6][7][10] 。
病因
肺高壓的病因常不明,也可由呼吸系統、循環系統疾病導致的肺動脈壓力增高。1973年,世界衛生組織首次嘗試將肺高壓分類,當時分為原發性肺高壓,以及次發性肺高壓兩大類,並將初級肺高壓分為「叢狀動脈型」(arterial plexiform)、「靜脈阻塞型」(veno-occlusive),以及「血栓栓塞型」(thromboembolic)等[12]。1988年埃維昂萊班會議將次級肺高壓按原因分類[13]。隨著新研究的進展,2008年在達納角召開的第四屆世界肺動脈高壓研討會更新了定義。以下為達納點的分類系統[4]:
治療
肺高壓可利用藥物控制病情發展的程度,若針對第一型肺動脈高目前主要分有三種不同的標靶治療途徑: 1.內皮素1 2前列環素(PGI:途徑) 3一氧化氮途徑 而目前針對此三種不同途徑的藥物如下列所述: 1.內皮素1途徑--Bosentan、Macitentan(雙重ETA-ETB拮抗劑)、Ambrisentan(選擇性ETA受體拮抗劑) 2.前列環素(PG₂I)途徑--Epoprostenol、lloprost、Treprostinil(三者皆為PGl₂類似劑)、Selexipag(PGl受體奮劑) 3.一氧化氮途徑--一氧化氮氣體(刺激可溶性鳥苷酸環化酶)、Sildenafil(PDE5抑利劑)、口服Riociguat(直接sGC刺激劑)[14] 由於肺高壓不能根治,若已引發較嚴重的心臟衰竭,就需要進行心肺移植,由於器官移植輪候需時,所以一旦確診,除藥物控制病情外,醫生都會安排病人排入器官移植的等候名單,以期病人在症狀惡化至嚴重心臟衰竭前,有適合器官進行移植手術[15]。
