BOSTON — Patients with COPD are at an increased risk for fatal pulmonary embolism (PE) and may require personalized, targeted thromboprophylaxis.
The data suggest that “maybe we should start thinking about if we are admitting a patient with COPD in that specific age group, higher thromboprophylaxis for PE,” said Marwa Oudah, MD, a pulmonary hypertension fellow at the University of Pennsylvania, Philadelphia. She presented her group’s findings in a rapid-fire oral abstract session at the CHEST Annual Meeting.
Known Risk Factor
COPD is a known risk factor for PE. To estimate how the obstructive lung disease may contribute to PE-related deaths among patients of varying ages, Oudah and colleagues drew data on deaths due to an underlying cause of PE from 1999 to 2020 from the Centers for Disease Control and Prevention’s WONDER database.
They stratified the patients into two groups — those with or without COPD — whose data were included in the Multiple Causes of Death dataset, according to age groups ranging from 35 years to over 100 years. The investigators calculated proportional mortality ratios in the non-COPD group and applied these to the COPD-positive group among different age ranges to estimate the observed vs expected number of deaths.
A total of 10,434 persons who died from PE and had COPD listed among causes of death were identified. The sample was evenly divided by sex. The peak range of deaths was among those aged 75-84 years.
The authors saw an increase in PE-related mortality among patients with COPD aged 65-85 years (P < .001).
The ratios of observed-to-expected deaths among patients in this age range were “substantially greater than 1” said Oudah, with patients aged 75-79 years at highest risk for PE-related death, with an observed-to-expected ratio of 1.443.
In contrast, the rate of observed deaths among patients aged 85-89 years was similar to the expected rate, suggesting that the COPD-PE interaction may wane among older patients, she said.
Among patients aged 35-64 years, the risk for death from PE was not significantly higher for any of the 5-year age categories.
The investigators emphasized that “given the observed trend, individualized patient assessments are imperative to optimize preventable measures against PE in the aging COPD population.”
Confounding Comorbidities
In an interview, a pulmonary specialist who was not involved in the study commented that older persons with COPD tend to have multiple comorbidities that may contribute to the risk for PE.
“Older patients have so many comorbidities, and their risk for pulmonary embolism and thromboembolic disease is pretty high, so I’m not surprised that 75 to 79 years olds are having a higher mortality from PE, but it’s a little difficult to say whether that’s due to COPD,” said Krishna Sundar, MBBS, MD, FCCP, a pulmonary, sleep medicine, and critical care medicine specialist at St. John’s Medical Center in Jackson, Wyoming, who moderated the session.
The authors did not report a study funding source. Oudah and Sundar reported no relevant financial relationships.
