OBJECTIVE: To analyze the clinical feature and prognosis during hospitalization of pulmonary thromboembolism(PTE) patients with hemoptysis. METHODS: Between January 2010 and January 2015, a total of 220 patients diagnosed with acute PTE were recruited in our study in Beijing Hospital. Baseline characteristics, clinical signs and symptoms, laboratory tests, imaging findings, therapy and hospitalization outcomes(including mortality, and incidences of bleeding events) were collected. All the patients were divided into two groups according to whether hemoptysis occurred. A variety of clinical parameters in clinical features and prognosis were compared between the two groups.RESULTS: Among 220 patients, 16(7.3%) had hemoptysis and 204(92.7%) did not. Hemoptysis group were significantly younger [(59.7±16.6)vs.(67.2±13.6) years, P=0.037] and there were more males(75.0% vs. 44.6%, P=0.034). Compared to patients without hemoptysis, those with hemoptysis had a higher incidence of fever(31.3% vs. 11.3%, P=0.037) and chest pain(50.0% vs. 26.0%; P=0.039). The average diagnosis time of hemoptysis group was(8.91 ± 6.09) days. Patients in the hemoptysis group had a higher proportion of inferior vena cava filter(IVCF)(18.8%vs. 3.4%, P=0.028). There was no significant difference in severity and in-hospital mortality between the two groups. CONCLUSION: The lack of specificity of hemoptysis caused by PTE often leads to misdiagnosis or delayed diagnosis. Early diagnosis is helpful to correct treatment and reduce the adverse consequences of improper measures.
