A total of 225 hospitalized patients who underwent CTPA examination between May 2018 and November 2021 in our hospital were diagnosed with acute pulmonary embolism and were followed up for 30 days. Follow up information was collected via phone calls. The inclusion criteria were patients diagnosed with APE according to the 2019 European Heart Association Guidelines for Diagnosis and Treatment of Acute Pulmonary Embolism,[4 (link)] 256-slice spiral CTPA examination, clinical data, and follow-up data. The exclusion criteria were other cardiac diseases that caused cardiac enlargement, including chronic pulmonary heart disease, rheumatic heart disease, congenital heart disease, cardiomyopathy, and poor computed tomographic angiography image quality.
All participants were divided into 2 groups, the death group and the non-death group, according to the prognosis data obtained 30 days after onset.
The Wells score, D-dimer, CK, and CK-MB data were also collected when the patients were diagnosed with APE. The Wells score criteria[3 (link)] were as follows: history of pulmonary embolism or deep venous thrombosis, heart rate ≥ 100 beats/minutes, history of operation or braking in the past 4 weeks, hemoptysis, active stage of malignant tumor, DVT-related symptoms, and low possibility of diagnosis other than pulmonary embolism. Each item is counted at 1 point. The normal D-dimer reference value was 0 to 0.243μg/mL. The blood and myocardial enzymes, including CK-MB, had normal reference values < 24MB.
