| Popis: | Pulmonary embolism (PE) is a common cardiovascular disease that can be easily missed or misdiagnosed. Electrocardiogram (ECG) is valuable in making early diagnoses and performing risk stratification with regard to acute PE.A total of 147 hospitalized patients diagnosed with acute PE were enrolled in this study and divided into the following 2 groups: main pulmonary artery trunk or main pulmonary artery (MPA) embolism and lobar artery or remote branch embolism. Electrocardiographic abnormalities associated with acute PE were subsequently identified.Electrocardiographic abnormalities were significantly different between the pulmonary trunk/MPA embolism group and the lobar artery/remote branch embolism group. The incidence of pulmonary trunk/MPA emboli was significantly related to the number of ECG abnormalities (t = -7.086, P = 5.556e-11). Furthermore, the number of ECG abnormalities noted among patients with pulmonary trunk/MPA emboli was 5.276 times greater than the number observed among the lobar artery/remote branch embolism group (P.001, 95% confidence interval = -6.57 to 3.97). The risk of either moderate or severe right ventricular hypertrophy was increased by 16.18% among patients with either pulmonary trunk or MPA emboli compared with patients with either lobar artery or remote branch emboli (P.001, 95% confidence interval = -2.76 to 0.876). The correct classification rate was as high as 92.3% when ECG was used to classify the prognosis of PE patients.The number of ECG abnormalities and the degree of right ventricular hypertrophy as determined via ECG can be used to assess the probability of developing a PE in the pulmonary trunk and MPA. Furthermore, ECGs can assist clinicians with risk stratification. |
