OBJECTIVE: Clinical presentation and short-term prognosis of patients with travel-associated acute pulmonary embolism (PE) (i.e., economy class syndrome [ECS]) is not well understood.
METHODS: In this retrospective cohort study of patients with acute PE identified from a single center registry, we assessed the clinical presentation and the association between ECS and the outcomes of all-cause mortality, PE-related mortality, nonfatal venous thromboembolism and nonfatal major bleeding rates through 30days after initiation of PE treatment.
RESULTS: Of the 2,333 patients with acute symptomatic PE, 124 (5.3%; 95% confidence interval, 4.4-6.3%) had ECS. Patients with ECS were younger and had fewer comorbid diseases (recent bleeding, chronic obstructive pulmonary disease, congestive heart failure), but they presented with more signs of clinical severity (syncope [48% vs. 14%; P<.001], tachycardia [37% vs. 21%; P<.001], right ventricular dysfunction [31% vs. 19%; P<.01] and myocardial injury [57% vs. 28%; P<.001]) compared to those without ECS. Regression analyses showed a significantly lower risk of all-cause mortality for patients with ECS compared to patients without ECS (1.6% vs. 9.6%; P<.01). We did not detect a difference in PE-related mortality at 30days between those with and those without ECS (0.8% vs. 3.1%; P=.18).
CONCLUSIONS: PE patients with ECS are younger and have fewer comorbid diseases compared to those without ECS. Though they present with more signs of clinical severity, their short-term prognosis is excellent.
