Background Pulmonary thromboembolism (PTE) is a common health problem that causes high mortality and morbidity. Its epidemiology is difficult to determine as it may be asymptomatic, or its diagnosis may be an incidental finding. Delayed diagnosis is a common cause of death; if caught early the risk may be temporary and reversible. Clinical manifestations of acute pulmonary embolism are highly variable. The aim of this research was to study patients’ clinical profiles and the association of risk factors with pulmonary thromboembolism diagnosis.
