Plasma non-targeted metabolomics unravels the metabolic features of normal trans-right heart.

Introduction: Right heart (RH), as a junction between the venous system and pulmonary circulation, gains great emphasis on exploring the relevant pathological mechanism of many cardiopulmonary diseases. Although these pathogensis researches centering on RH-related diseases advance, the physiological mechanism research of the RH is scarce.

Objectives: This study aimed to accurately unravel the metabolic features of normal trans-RH through non-targeted metabolomics.

Direct oral anticoagulants in the treatment of chronic thromboembolic pulmonary hypertension patients: A retrospective cohort study.

Introduction: Direct oral anticoagulants (DOACs) are increasingly prescribed for life-long anticoagulation in chronic thromboembolic pulmonary hypertension (CTEPH) patients, despite not being recommended in the guidelines. This study aims to evaluate the efficacy and safety of DOACs in CTEPH patients.

Methods: From May 2013 to December 2022, patients who were first diagnosed with CTEPH in Fuwai Hospital and started long-term anticoagulation treatment with warfarin or DOACs were retrospectively included and followed up until (1) death, (2) transition to other kinds of anticoagulants, or (3) discontinuation of anticoagulation.

Untargeted metabolomics reveal the metabolic profile of normal pulmonary circulation.

Background: As an important place of material exchange, the homeostasis of the pulmonary circulation environment and function lays an essential foundation for the normal execution of various physiological functions of the body. Small metabolic molecules in the circulation can reflect the corresponding state of the pulmonary circulation.

Methods: We enrolled patients with Patent Foramen Ovale and obtained blood from the pulmonary arteries and veins through heart catheterization.

Clinical and Safety Outcomes Associated with Extended Treatment of Venous Thromboembolism: A Network Meta-Analysis.

Background: Many anticoagulant strategies are available for the extended treatment of venous thromboembolism, yet little guidance exists regarding which drug is most effective and safe.

Aim: A network meta-analysis was performed to resolve this uncertainty.

Methods: We searched the medical literature through June 2022 for randomized controlled trials (RCTs) evaluating the efficacy and safety of anticoagulants for adults with VTE compared with other anticoagulants or a placebo.
