Abstract:
Objective The study aimed to analyze the clinical data of patients with pulmonary embolism and summarize the clinical characteristics of pulmonary embolism,in order to improve the correct diagnostic rate and the prognosis. Methods Data of 178 patients who were cured in our hospital from January 2011 to December 2014 were analyzed retrospectively,including relative risk factors,clinical behaviors,examination data,misdiagnosis and prognosis. Results Patients with pulmonary embolism had related basic diseases and risk factors. Their clinical symptoms,signs and ordinary detection methods indicated pneumatorexis and cardiovascular injury,but lacked of specificity. The misdiagnosis rate of the first diagnosis was 48.88%,including 22 cases of the misdiagnosis to COPD, 18 cases to pneumonia and 16 cases to coronary heart disease. The misdiagnosis rate of elderly patients was 56.36%, while that of the young and middle-aged patients was 36.80%,the difference was statistically significant,P < 0.05. Computed tomography pulmonary angiography(CTPA)could accurately observe the pathological changes of pulmonary embolism,and all the patients were diagnosed by CTPA in the research. 11 cases(10%)of elderly patients died,while 2 cases(2.9%)happened in young and middle-aged patients. There was no statistical significant difference(P > 0.05). Conclusion Although the related risk factors of pulmonary embolism in patients existed,the misdiagnosed rate of the disease was high and prognosis was poor due to many confusing basic diseases. And the symptoms,signs and ordinary inspection of the patients lacked specificity. CTPA,being utilized to diagnose pulmonary embolism reliably,should be promoted.
