AbstractTo explore the clinical manifestations and factors leading to misdiagnosis in pulmonary embolism (PE) patients in a cardiology department. We retrospectively analyzed 74 patients diagnosed with PE at our hospital from March 2018 to March 2022, comparing them to 136 patients suspected of PE but excluded by computed tomography pulmonary angiography during the same period. Both groups received the same basic care, including disease counseling, nutritional planning, and monitoring. We compared general information, clinical manifestations, risk factors, and auxiliary examinations to identify correlations between specific manifestations and misdiagnosis factors. The male-to-female ratio in the PE group was approximately 3:4, which was statistically significant compared to the control group (P < .05), though its impact on PE incidence was low. Common symptoms in the PE group included chest tightness, shortness of breath, sweating, and chest pain, with no significant difference from the control group (P > .05). Notable risk factors included deep vein thrombosis (DVT) (43.24%), prolonged bed rest (32.43%), lower limb varicose veins (18.92%), trauma (21.62%), pulmonary infections (62.16%), coronary heart disease (37.84%), respiratory failure (32.43%), and chronic obstructive pulmonary disease (13.51%). DVT was significantly associated with PE (P < .05). Multivariate logistic regression identified DVT (OR = 118.528, 95% CI: 6.959-2018.906, P = .001) and lower limb varicose veins (OR = 212.766, 95% CI: 6.584-6875.950, P = .003) as independent predictive factors for suspected PE. Clinical manifestations strongly correlated with PE included pulmonary rales, cyanosis, tachycardia, hypotension, elevated D-dimer, positive N-terminal pro-brain natriuretic peptide, and sinus tachycardia on echocardiogram. PE in cardiology patients may present with pulmonary rales, hypotension, shortness of breath, and abdominal symptoms, warranting reexamination for PE. Misdiagnosis factors typically involve chest pain, tightness, and shortness of breath. Lower limb varicose veins and DVT are reliable predictors of suspected PE.Copyright © 2024 the Author(s).
