Prediction of pulmonary embolism by an explainable machine learning approach in the real world.
Sci Rep
January 2025
Department of Respiratory and Critical Care Medicine, Changhai Hospital, The Second Military Medical University, Shanghai, People's Republic of China.
In recent years, large amounts of researches showed that pulmonary embolism (PE) has become a common disease, and PE remains a clinical challenge because of its high mortality, high disability, high missed and high misdiagnosed rates. To address this, we employed an artificial intelligence-based machine learning algorithm (MLA) to construct a robust predictive model for PE. We retrospectively analyzed 1480 suspected PE patients hospitalized in West China Hospital of Sichuan University between May 2015 and April 2020.

Objective: To investigate the effectiveness of initial hemostatic resuscitation(IHR) on the treatment of bleeding with recombinant human coagulation factor VIIa after cardiac surgery.
Methods: The clinical data of patients who received rFVIIa hemostatic treatment after cardiac surgery at Beijing Anzhen Hospital, Capital Medical University, from January 1, 2021, to December 31, 2021 were retrospectively collected. A total of 152 cases were included in the study.
Heparin rebound in patients undergoing off-pump coronary artery bypass grafting surgery: a single-center retrospective study.
J Cardiothorac Surg
January 2025
Department of Anesthesiology, Fuwai Hospital, National Center for Cardiovascular Diseases, Peking Union Medical College and Chinese Academy of Medical Sciences, No. 167, Beilishi Road, Xicheng District, China.
Background: Heparin, an anticoagulant used in cardiac surgery, can result in heparin rebound (HR), where it returns postoperatively despite being neutralized with protamine. This study was designed to investigate the prevalence of HR in patients undergoing off-pump coronary artery bypass grafting (OPCAB) and evaluate the impact of HR on their short-term outcomes.
Methods: HR was defined by a 10% increase in activated coagulation time (ACT) following two hours of heparin neutralization with protamine, bleeding over 200 mL/h, and abnormal laboratory coagulation examination results.
Fibrin film on clots is increased by haematocrit but reduced by inflammation: implications for platelets and fibrinolysis.

Discovery and Translational Science Department, Leeds Institute of Cardiovascular and Metabolic Medicine, University of Leeds, Leeds, UK.
Background: Blood clot formation, triggered by vascular injury, is crucial for haemostasis and thrombosis. Blood clots are composed mainly of fibrin fibres, platelets and red blood cells (RBCs). Recent studies show that clot surface also develops a fibrin film, which provides protection against wound infection and retains components such as RBCs within the clot.

Ethnopharmacological Relevance: Cryptotanshinone serves as the principal bioactive constituent of Salvia miltiorrhiza Bunge, possesses a wide range of pharmacological activities. Salvia miltiorrhiza Bunge, a long-standing therapeutic agent in traditional Chinese medicine (TCM) practice, is renowned for its efficacy in enhancing blood circulation and alleviating blood stasis and infarction, thereby treating cardiovascular and cerebrovascular diseases.
Aim Of The Study: Platelet activation, when excessive or aberrant, poses a significant risk, catalyzing the onset of various thrombotic disorders.
