Abstract

BACKGROUND AND OBJECTIVE: Severe idiopathic pulmonary fibrosis is associated with an increased risk of cardiovascular disease and gastro-oesophageal reflux, which may influence prognosis. We evaluated associations between cardiovascular and antacid medications, and mortality, in oxygen-dependent pulmonary fibrosis (PF) of unknown cause.

METHODS: Prospective population-based study of adults starting long-term oxygen therapy (LTOT) for PF in Sweden 2005-2009. PF of unknown cause was defined by excluding patients with known or probable secondary PF. Time-dependent associations between medications and all-cause mortality were analysed using extended Cox regression, adjusting for potential confounders including age, sex, vital capacity, blood gases, body mass index, performance status, comorbidity and concurrent medications.

RESULTS: Of 462 included patients, 329 (71%) died under observation. No patient was lost to follow-up. Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB) were associated with reduced adjusted mortality (HR 0.63; 0.47-0.85) and antiplatelet drugs with increased mortality (HR 1.49; 1.11-2.00), largely driven by higher mortality in women. There were no associations with mortality for antacid treatments, β-blockers, diuretics or statins.

CONCLUSION: In oxygen-dependent PF, treatment with ACEI/ARB was associated with improved survival, antiplatelet drugs with decreased survival, whereas there was no association between antacid, β-blocker, diuretic or statin treatment and survival.
