Background: Diagnosing pulmonary embolisms can be challenging, given that its presentation shares clinical manifestations with other conditions. For patients 80 years of age or older, the healthcare challenge increases due to associated comorbidity when compared with younger patients (<80 years).
Objective: The aim of our study was to report the incidence of pulmonary embolism in elderly patients in our setting and identify differences in the clinical manifestations, comorbidity and laboratory parameters between these 2 groups of patients.
Method: We conducted a hospital-based, case-control study to review the pulmonary embolisms diagnosed in our centre using computed tomography pulmonary angiography between 2013 and 2016.
Results: The study included 413 patients, 124 of whom were 80 years of age or older, with a median age of 72 years (IQR, 58-81). The typical presentation triad was uncommon and showed no differences between subgroups. The main symptoms presented by these groups were dyspnoea (73.4% vs. 63.7% for the elderly and younger groups, respectively; P=.055), chest pain (26.6% vs. 39.5%; P=.013) and cough/haemoptysis (31.1% vs. 18.9%; P=.021). The elderly group had more comorbidity (4.88±2.55 vs. 2.89±2.85; P=.0001).
Conclusion: Thirty percent of the pulmonary embolisms occurred in the elderly group. The typical presentation form was uncommon. We detected significant differences in individual symptoms, comorbidity and laboratory parameters compared with the younger patients.
