Pulmonary embolism in ischemic stroke: clinical presentation, risk factors, and outcome.
Limited information is available on the frequency of pulmonary embolism (PE) in patients with an acute ischemic stroke (AIS). We evaluated clinical characteristics, predisposing factors, and outcomes in AIS patients with PE. ⋯ In this large cohort study, PE occurred in nearly 1% of AIS patients. PE was more common in patients with severe stroke, history of cancer, previous DVT/PE or acute DVT and associated with lower short- and long-term survival, greater disability, and longer length of stay.
