The Importance of Dose Escalation in the Treatment of Pulmonary Arterial Hypertension with Treprostinil.

: Treprostinil, which is administered via continuous subcutaneous or intravenous infusion, is a medication applied in the treatment of pulmonary arterial hypertension (PAH). The dose of treprostinil is adjusted on an individual basis for each patient. A number of factors determine how well patients respond to treatment.

Exploring the patient perspective in pulmonary hypertension.

The global impacts of pulmonary hypertension (PH) were formally recognised in 1973 at the 1st World Health Organization meeting dedicated to primary pulmonary hypertension, held in Geneva. Investigations into disease pathogenesis and classification led to the development of numerous therapies over the ensuing decades. While the impacts of the disease have been lessened due to treatments, the symptoms and adverse effects of PH and its therapies on patients' wellbeing and mental health remain significant.

Initial combination therapy with macitentan and tadalafil in patients with pulmonary arterial hypertension, with and without cardiac comorbidities.

Aims: According to current guidelines, initial monotherapy should be considered for pulmonary arterial hypertension (PAH) patients with cardiopulmonary comorbidities. This analysis of combined data from the TRITON and REPAIR clinical trials, assesses efficacy and safety of initial double combination therapy in patients without vs. with 1-2 cardiac comorbidities.

Myo-inositol trispyrophosphate prevents right ventricular failure and improves survival in monocrotaline-induced pulmonary hypertension in the rat.

Background And Purpose: Pulmonary hypertension (PH) results from pulmonary vasculopathy, initially leading to a compensatory right ventricular (RV) hypertrophy, and eventually to RV failure. Hypoxia can trigger both pulmonary vasculopathy and RV failure. Therefore, we tested if myo-inositol trispyrophosphate (ITPP), which facilitates oxygen dissociation from haemoglobin, can relieve pulmonary vasculopathy and RV hypoxia, and eventually prevent RV failure and mortality in the rat model of monocrotaline-induced PH.

Safety and Outcomes of Inferior Vena Cava Filter Placement in Oncology Patients: A Single-Centre Experience.

The risk of venous thromboembolism (VTE) in the oncology population is significantly higher than in non-cancer patients. Inferior vena cava (IVC) filters may, therefore, be an important part of VTE treatment. In this study, we address the outcomes of placing IVC filters in the oncology population.

Chronic thromboembolic disease among patients undergoing surgical pulmonary embolectomy for acute pulmonary embolism.

Background: This study aimed to assess the prevalence of chronic thromboembolic lesions in the pulmonary arteries among patients undergoing pulmonary embolectomy for acute pulmonary embolism and their impact on treatment outcomes.

Methods: We conducted a retrospective, single-center analysis of consecutive patients undergoing emergency pulmonary embolectomy for acute pulmonary embolism between 2013 and August 2021. According to European Society of Cardiology guidelines, the diagnosis was based on clinical presentation, imaging studies and laboratory tests.

Comparison of cardiac magnetic resonance imaging, functional and haemodynamic variables in pulmonary arterial hypertension: insights from REPAIR.

Background: Measures that can detect large treatment effects are important for monitoring therapeutic effectiveness. The 2022 European Society of Cardiology/European Respiratory Society guidelines highlight the importance of imaging in monitoring disease status and treatment response in pulmonary arterial hypertension (PAH). Are the standardised treatment effect sizes (STES) of cardiac magnetic resonance imaging (cMRI) comparable with functional and haemodynamic variables?

Methods: REPAIR (ClinicalTrials.

Effect of Macitentan in Pulmonary Arterial Hypertension and the Relationship Between Echocardiography and cMRI Variables: REPAIR Echocardiography Sub-study Results.

Introduction: The aim of this sub-study was to evaluate the relationship between echocardiography (echo) and cardiac magnetic resonance imaging (cMRI) variables and to utilize echo to assess the effect of macitentan on right ventricle (RV) structure and function.

Methods: REPAIR (NCT02310672) was a prospective, multicenter, single-arm, open-label, 52-week, phase 4 study in pulmonary arterial hypertension (PAH) patients, which investigated the effect of macitentan 10 mg as monotherapy, or in combination with a phosphodiesterase 5 inhibitor, on RV structure, function, and hemodynamics using cMRI and right heart catheterization. In this sub-study, patients were also assessed by echo at screening and at weeks 26 and/or 52.

The Utility of a Resting Electrocardiogram (ECG-PH Index) in Evaluating the Efficacy of Pulmonary Endarterectomy in Chronic Thromboembolic Pulmonary Hypertension.

Background: The ECG-PH index (PH-ECG score) has been proposed as a valuable ECG-derived method of evaluating the effectiveness of balloon pulmonary angioplasty (BPA) in chronic thromboembolic pulmonary hypertension (CTEPH). Pulmonary endarterectomy (PEA) is the main form of therapy for CTEPH with a proximal clot location. The objective of this study was to assess the clinical utility of a resting electrocardiogram (ECG-PH index) in assessing the effectiveness of PEA in CTEPH patients.

The risk profile change in patients with severe chronic thromboembolic pulmonary hypertension treated with subcutaneous treprostinil.

Chronic thromboembolic pulmonary hypertension (CTEPH) is successfully treatable with pulmonary endarterectomy (PEA), balloon pulmonary angioplasty, and medical therapy. Registry to Evaluate Early and Long-Term Pulmonary Arterial Hypertension Disease Management risk score (RRS) is able to predict long-term outcome in inoperable patients or in patients with residual PH after surgery. We performed a post hoc analysis of RRS in patients who were enrolled in the CTREPH study (NCT01416636), a randomized, double-blind clinical trial comparing high-dose and low-dose subcutaneous (SC) treprostinil in patients with severe CTEPH that was classified by an interdisciplinary CTEPH team as nonoperable, or as persistent or recurrent pulmonary hypertension after PEA.

Treatment of high- and intermediate-high-risk pulmonary embolism by the Pulmonary Embolism Response Team: Focus on catheter-directed therapies.

Background: Multidisciplinary Pulmonary Embolism Response Teams (PERTs) were established to individualize the treatment of high-risk (HR) and intermediate-high-risk (IHR) pulmonary embolism (PE) patients, which pose a challenge in clinical practice.

Methods: We retrospectively collected the data of all HR and IHR acute PE patients consulted by PERT CELZAT between September 2017 and October 2022. The patient population was divided into four different treatment methods: anticoagulation alone (AC), systemic thrombolysis (ST), surgical embolectomy (SE), and catheter-directed therapies (CDTx).

The Diagnostic Approach to Pulmonary Hypertension.

The clinical presentation of pulmonary hypertension (PH) is nonspecific, resulting in significant delays in its detection. In the majority of cases, PH is a marker of the severity of other cardiopulmonary diseases. Differential diagnosis aimed at the early identification of patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) who do require specific and complex therapies is as important as PH detection itself.

European Society of Cardiology quality indicators for the care and outcomes of adults with pulmonary arterial hypertension. Developed in collaboration with the Heart Failure Association of the European Society of Cardiology.

Aims: To develop a suite of quality indicators (QIs) for the evaluation of the care and outcomes for adults with pulmonary arterial hypertension (PAH).

Methods And Results: We followed the European Society of Cardiology (ESC) methodology for the development of QIs. This included (i) the identification of key domains of care for the management of PAH, (ii) the proposal of candidate QIs following systematic review of the literature, and (iii) the selection of a set of QIs using a modified Delphi method.

Acute pulmonary embolism with coexisting right heart thrombi in transit-surgical treatment of 20 consecutive patients.

Objectives: The presence of right heart thrombi in transit (RHTiT) in the setting of acute pulmonary embolism (PE) is associated with high mortality. The optimal management in such cases is inconclusive. We present the results of surgical treatment of 20 consecutive patients diagnosed with high- or intermediate-high-risk PE with coexisting RHTiT.

Outcomes of COVID-19 in patients vaccinated and unvaccinated against SARS-CoV-2 and suffering from pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension.

Introduction: Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) lead to progressive right heart failure. The mortality rates in PAH and CTEPH patients due to COVID‑19 are high, and vaccination against COVID‑19 is recommended in this group.

Objectives: We analyzed the incidence and outcomes of COVID‑19in the PAH/CTEPH patients for 2 years of the pandemic, as well as the predictors of worse outcomes of COVID‑19 in this group.

Long-Term Safety, Tolerability and Survival in Patients with Pulmonary Arterial Hypertension Treated with Macitentan: Results from the SERAPHIN Open-Label Extension.

Introduction: In SERAPHIN, a long-term, event-driven, double-blind randomised controlled trial in pulmonary arterial hypertension (PAH), macitentan 10 mg significantly reduced the risk of morbidity/mortality compared with placebo. Its open-label extension study (SERAPHIN OL) further assessed long-term safety and tolerability of macitentan 10 mg in PAH patients.

Methods: Patients in SERAPHIN who completed the double-blind treatment period or experienced a morbidity event during the study could enter SERAPHIN OL.

An expert opinion of the Polish Cardiac Society Working Group on Pulmonary Circulation on screening for chronic thromboembolic pulmonary hypertension patients after acute pulmonary embolism: Update.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism (APE). Both pharmacological and invasive treatments for CTEPH are available in Poland, and awareness of the disease among physicians is growing. It has been suggested that the COVID-19 pandemic may increase the incidence of CTEPH and facilitate disease detection during more advanced stages of the illness.

Prostacyclin analogues decrease platelet aggregation but have no effect on thrombin generation, fibrin clot structure, and fibrinolysis in pulmonary arterial hypertension: PAPAYA coagulation.

Prostacyclin (PGI) analogues (epoprostenol, treprostonil, iloprost) are the cornerstone of pulmonary arterial hypertension (PAH) treatment. PGI analogues inhibit platelet reactivity, but their impact on coagulation and fibrinolysis parameters has not been elucidated. We compared platelet reactivity, thrombin generation, clot permeation, and lysis properties in patients with PAH treated with PGI analogues (n = 20) and those not receiving PGI analogues (n = 20).
