  • The Potential for Macitentan, a New Dual Endothelin Receptor Antagonist, in the Treatment of Pulmonary Arterial Hypertension
  • (Medscape) In recent years in the management of pulmonary arterial hypertension (PAH), endothelin receptor antagonists (ERAs) represent a well-established class of therapeutic agents with clear beneficial effects. Macitentan (Opsumit®), a dual ERA optimized for efficacy and safety, is the newest drug in the class. Macitentan presents a number of key beneficial characteristics, including increased in vivo preclinical efficacy versus existing ERAs, resulting from sustained receptor binding and physicochemical properties that allow enhanced tissue penetration. The clinical pharmacokinetics studies also indicated a low predilection of macitentan for drug–drug interactions. In the SERAPHIN trial, a phase III long-term study of PAH, macitentan significantly reduced morbidity and mortality by 45% versus placebo, providing sustained long-term improvements in exercise capacity. No association was found between changes in exercise capacity and long-term clinical outcomes, but improved cardiopulmonary hemodynamics were recorded in macitentan-treated patients irrespective of baseline background PAH therapy or World Health Organization functional class. Based on these favorable data, the US Food and Drug Administration approved the 10 mg/day dose in late 2013 and the same process has recently been concluded by the European Medicines Agency.

  • Pulmonary Hypertension Is Related to Peripheral Endothelial Dysfunction in Heart Failure With Preserved Ejection Fraction
  • (AHA Journals) Pulmonary hypertension and collagen metabolism abnormalities are prevalent in patients with HFpEF. Peripheral endothelial dysfunction (PED) has been described in heart failure (HF), as well as in pulmonary arterial hypertension. Our aim is to determine whether pulmonary hypertension is associated with PED and impaired collagen metabolism in patients with heart failure and preserved ejection fraction (HFpEF).

  • Up-Regulated LCN2 in PH Involving in PASMC Resistance to Apoptosis
  • (Int J Biol Sci) A key feature of pulmonary hypertension (PH) is the remodeling of small pulmonary arteries due to abnormal pulmonary artery smooth muscle cell (PASMC) proliferation and resistance to apoptosis. However, the cellular mechanisms underlying how PASMCs in the pathological condition of pulmonary hypertension become resistant to apoptosis remain unknown. It was recently reported that lipocalin 2 (Lcn2) is up-regulated in a wide array of malignant conditions, which facilitates tumorigenesis partly by inhibiting cell apoptosis. In this study, we observed that the expression levels of Lcn2 were significantly elevated in a rat PH model induced with monocrotaline and in patients with congenital heart disease-associated PH (CHD-PH) when compared with respective control.

  • Making Pulmonary Pressure Measurements Safer For PH Patients Using Ultrasound
  • (Pulmonary Hypertension News) A group of researchers from Flinders Medical Centre and Flinders University in Australia are working to make measuring pulmonary pressures safer for patients with pulmonary hypertension. Their study, published in Critical Ultrasound Journal,investigated the use of ultrasound-echocardiography for estimating mean pulmonary arterial pressure in critically ill patients. Although the results were not on-par with those from the accepted standard, more work may refine the technique to provide a less invasive monitoring system.

  • Major Signaling Pathway in Scleroderma May Enable Effective Treatments, Cures
  • (Pulmonary Hypertension News) As any scleroderma patient knows, the disease has no cure and no effective treatments exist. The main goal of current treatments is reducing inflammation which, often times, is not enough to provide relief to patients, especially those who have developed pulmonary hypertension as a result of thickened pulmonary arteries.

  • New PAH-Related Hospitalization Study Released
  • (Pulmonary Hypertension News) Lead author Charles Burger, MD, from the Mayo Clinic, and colleagues reported their findings in Chest. Data was gathered for 862 patients, and 490 (56.8%) experienced at least one hospitalization during their first three years post-diagnosis. 490 of the total had experienced at least one hospitalization during the 3-year follow-up period. 52.4% of the hospital admissions were PAH-related, while 43.7% were unrelated to the disease and 3.9% were due to undetermined causes. Half were related to the patients’ PAH, and the mean total number of days spent in the hospital was 15.3 days. Not only is a hospital stay burdensome to patients, but also it places a burden on the healthcare system.

If the clot came loose, the consequences would likely be catastrophic for the patient, who suffered from pulmonary hypertension - a dangerous narrowing of blood vessels connecting the heart and lungs.

    But experts at the UC San Diego Sulpizio Cardiovascular Center (SCVC) are now able to save patients like this one from potentially fatal outcomes by using a new technology capable of removing blood clots, infected masses or foreign bodies from major cardiac blood vessels without performing open-heart surgery.....

  • The LARIAT trial: PAH clinical trial using bardoxolone methyl
  • (pulmonaryhypertensionnews.com) The molecular and pharmacological effects of bardoxolone methyl are broad through its induction of Nrf2 and suppression of NF-κB. Bardoxolone methyl may therefore address multiple facets of the pathophysiology of PAH because it suppresses activation of proinflammatory mediators, enhances endothelial NO bioavailability, improves metabolic dysfunction, suppresses vascular proliferation, and prevents maladaptive remodeling. Furthermore, while existing therapies primarily target only smooth muscle cells, bardoxolone methyl targets multiple cell types relevant to PAH, including endothelial cells, smooth muscle cells, and macrophages.
