Frequency and predictors for chronic thromboembolic pulmonary hypertension after a first unprovoked pulmonary embolism: Results from PADIS studies.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening complication of a pulmonary embolism (PE) whose incidence and predictors are not precisely determined.

Objective: To determine the frequency and predictors for CTEPH after a first unprovoked PE.

Patients/methods: In a randomized trial comparing an additional 18-month warfarin versus placebo in patients after a first unprovoked PE initially treated with vitamin K antagonist for 6 months, we applied recommended CTEPH screening strategies through an 8-year follow-up to determine cumulative incidence of CTEPH.

Evaluation of Venous Thromboembolism Recurrence Scores in an Unprovoked Pulmonary Embolism Population: A Post-hoc Analysis of the PADIS-PE trial.

Background: We aimed to validate the Men Continue and HERDOO2 (HERDOO2), D-dimer, age, sex, hormonal therapy (DASH), and updated Vienna recurrent venous thromboembolism prediction models in a population composed entirely of first unprovoked pulmonary embolism, and to analyze the impact of the addition of the pulmonary vascular obstruction index (PVOI) on score accuracy.

Methods: Analyses were based on the double-blind, randomized PADIS-PE trial, which included 371 unprovoked pulmonary embolism patients initially treated for 6 months, successively randomized to receive an additional 18 months of warfarin or placebo, and subsequently followed-up for 2 years.

Results: The HERDOO2, DASH, and updated Vienna scores displayed C-statistics of 0.

Evaluation of the predictive value of the bleeding prediction score VTE-BLEED for recurrent venous thromboembolism.

Introduction: VTE-BLEED is a validated score for identification of patients at increased risk of major bleeding during extended anticoagulation for venous thromboembolism (VTE). It is unknown whether VTE-BLEED high-risk patients also have an increased risk for recurrent VTE, which would limit the potential usefulness of the score.

Methods: This was a post hoc analysis of the randomized, double-blind, placebo-controlled PADIS-PE trial that randomized patients with a first unprovoked pulmonary embolism (PE) initially treated during 6 months to receive an additional 18-month of warfarin vs.

Predictors for Residual Pulmonary Vascular Obstruction after Unprovoked Pulmonary Embolism: Implications for Clinical Practice-The PADIS-PE Trial.

Background:  We aimed to identify risk factors for residual pulmonary vascular obstruction after a first unprovoked pulmonary embolism (PE).

Methods:  Analyses were based on data from the double-blind randomized "PADIS-PE" trial that included 371 patients with a first unprovoked PE initially treated during 6 uninterrupted months; all patients underwent baseline ventilation-perfusion lung scanning at inclusion (i.e.

Risk factors for recurrent venous thromboembolism after unprovoked pulmonary embolism: the PADIS-PE randomised trial.

We aimed to identify risk factors for recurrent venous thromboembolism (VTE) after unprovoked pulmonary embolism.Analyses were based on the double-blind randomised PADIS-PE trial, which included 371 patients with a first unprovoked pulmonary embolism initially treated during 6 months who were randomised to receive an additional 18 months of warfarin or placebo and followed up for 2 years after study treatment discontinuation. All patients had ventilation/perfusion lung scan at inclusion ( at 6 months of anticoagulation).
