Long-term prognosis and related factors towards patients with acute pulmonary thromboembolism

This study aims to investigate the long-term prognosis and the affecting factors towards the patients with acute pulmonary thromboembolism (APTE). The clinical data of 903 PTE patients, diagnosed by the spiral CT pulmonary angiography (CTPA) or lung ventilation perfusion scanning when hospitalized in the Second Hospital of Hebei Medical University from January 1998 to December 2013, were collected, among who 548 patients were performed the long-term follow-up, and the factors that would affect the prognosis were statistically analyzed. The univariate analysis showed that many factors would affect the prognosis of PTE. The multivariate non-conditional logistic regression analysis showed that: the relevant factors of re-embolization included the idiopathic pulmonary embolism, RVD, D-dimer positive, anticoagulation treatment < 3 months, post-treatment PASP > 40 mmHg, the relevant factors of death included the D-dimer positive, anticoagulation treatment < 3 months, cTnI positive, post-treatment PASP > 40 mmHg. RVD and post-treatment PASP > 40 mmHg would increase the risk of chronic thromboembolic pulmonary hypertension (CTEPH). The idiopathic pulmonary embolism, RVD, D-dimer positive, anticoagulation treatment < 3 months, cTnI positive and post-treatment PASP > 40 mmHg were the important factors that would affect the long-term prognosis of PTE patients.
