Incidence of Acute Pulmonary Embolism in a General Hospital: Conclusion

Whether the prevalence of PE shows a bias related to sex is unclear. Regarding patients of all ages, some autopsy studies showed no significant difference of the incidence of PE or venous thromboembolism based on sex. An autopsy study at a general hospital showed a higher prevalence of PE among women. Others showed a higher […]

Incidence of Acute Pulmonary Embolism in a General Hospital: Discussion

Population-based investigations and autopsy studies have shown that acute PE occurs predominantly in middle-aged and elderly people. Among patients who died of PE, 82% were > 41 years of age. Among deaths attributed to PE based on death certificates, 97% were > 40 years of age. Among 4,391 autopsies, there was an almost linear increase […]

Incidence of Acute Pulmonary Embolism in a General Hospital: Results

During the 4.75-year period of study, there were 175,730 patients admitted to the hospital. Among these, PE was diagnosed in 400 patients. The diagnosis was made in 256 patients by a high-probability V/Q lung scan, and in 144 patients by pulmonary angiography. The incidence of PE was 0.23% (95% CI, 0.21 to 0.25%). The incidence […]

Incidence of Acute Pulmonary Embolism in a General Hospital: Materials and Methods

A high-probability interpretation of the V/Q lung scan based on evidence from the Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) has become an accepted basis for the diagnosis of PE and was used as an objective indicator of PE in previous investigations of the incidence of PE. The positive predictive value of a high-probability interpretation […]

Incidence of Acute Pulmonary Embolism in a General Hospital

Although venous thromboembolism is the third most common cardiovascular disease after acute ischemic syndromes and stroke, the incidence of pulmonary embolism (PE) according to age in a general hospital, to our knowledge, has not been reported. The incidence according to sex has been sparsely studied, as has the incidence according to race. Prior to 1960, […]
