Fifty-three patients without pre-existing cardiac or pulmonary disease were reviewed 5 to 9 years after angiographically proved pulmonary embolism. Ten of the 42 (24%) with an initial predisposing factor for embolism had died, including 6 from a previously diagnosed medical condition. In this group there was no significant residual disability among survivors and no late recurrence of embolism. By comparison, there were 6 deaths among the 11 in whom no predisposing factor was identified (55%), including 3 from neoplasm and 2 from recurrent embolism with cardiac failure. The identification of a predisposing factor at the time of embolism was associated with a significantly better long-term prognosis.
对53例无心脏或肺部基础疾病且经血管造影证实有肺栓塞的患者进行了5至9年的随访。42例（24%）最初有栓塞诱发因素的患者中有10例死亡，其中6例死于先前诊断的疾病。该组幸存者中无明显的残留残疾，也无栓塞晚期复发。相比之下，11例未发现诱发因素的患者中有6例死亡（55%），其中3例死于肿瘤，2例死于复发性栓塞伴心力衰竭。栓塞时发现诱发因素与显著更好的长期预后相关。
