Pulmonary embolism may be cause of syncope in some elderly
(HealthDay)—About one of every six patients hospitalized for a first episode of syncope has a pulmonary embolism, according to a study published in the Oct. 20 issue of the New England Journal of Medicine.
Researchers at 11 hospitals in Italy performed a systematic work-up for pulmonary embolism in 560 patients admitted for a first-time syncope episode. The patients were 76 years old, on average, and had been admitted from the emergency department for various reasons: The cause of syncope was not apparent; there was reason to suspect a cardiovascular-related cause; they had other serious medical conditions; or they'd been injured when they fainted.
The team found that 17.3 percent—or roughly one in six—were diagnosed with pulmonary embolism. That included 13 percent of patients who'd had a potential alternative explanation for their syncope, such as a cardiovascular condition.
"In elderly patients presenting with syncope, the attending physician in medical wards should consider pulmonary embolism as a possible differential diagnosis—particularly when an alternative explanation is not found," study coauthor Sofia Barbar, M.D., a physician at the Civic Hospital of Camposampiero in Padua, Italy, told HealthDay.
