Low-density lipoprotein cholesterol(LDL-C) is a well established metabolic marker of cardiovascular risk, however, its role in pulmonary arterial hypertension (PAH) has not been determined. Therefore we assessed whether LDL-C levels are altered in PAH patients, if they are associated with survival in this group and whether pulmonary hypertension (PH) reversal can influence LDL-C levels. Consecutive 46 PAH males and 94 females were age matched with a representative sample of 1168 males and 1245 females, respectively...

Our understanding of the pathophysiological basis of chronic thromboembolic pulmonary hypertension (CTEPH) will be accelerated by an animal model that replicates the phenotype of human CTEPH. Sprague-Dawley rats were administered a combination of a single dose each of plastic microspheres and vascular endothelial growth factor receptor antagonist in polystyrene microspheres (PE) + tyrosine kinase inhibitor SU5416 (SU) group. Shams received volume-matched saline; PE and SU groups received only microspheres or SU5416, respectively...

In chronic thromboembolic pulmonary hypertension (CTEPH), stenoses or obstructions of the pulmonary arteries due to organized thrombi can cause an elevation in pulmonary artery resistance, which in turn can result in pulmonary hypertension and progressive right heart failure. CTEPH can be cured surgically by pulmonary endarterectomy (PEA); however, patients deemed unsuitable for PEA due to distal lesion, advanced age, or comorbidities have a poor prognosis and limited treatment options. Recently, an alternative interventional strategy of balloon pulmonary angioplasty (BPA) reduces pulmonary artery hypertension in patients with CTEPH...

The pathomechanisms underlying the development of thrombofibrotic pulmonary artery occlusions in Chronic Thromboembolic Pulmonary Hypertension (CTEPH) are largely unknown. The aim of this study was to allocate distinct cellular processes playing a role in thrombus resolution, such as inflammation, hypoxia, proliferation, apoptosis and angiogenesis, to different stages of thrombofibrotic remodelling. A total of 182 pulmonary endarterectomy (PEA) specimens were collected from 31 CTEPH patients. To facilitate co-localisation, Tissue MicroArrays were prepared and processed for (immuno)-histochemistry and confocal fluorescence microscopy...

Chronic thromboembolic pulmonary hypertension (CTEPH) is the most severe long term complication of acute pulmonary embolism (PE). Untreated, CTEPH is associated with a very poor prognosis and high risk of mortality, although curation can be achieved by surgical removal of the obstructive endothelialised thromboemboli from the pulmonary arteries. Early CTEPH diagnosis may improve surgical possibilities and patients outcome. Currently, early diagnosis of CTEPH is a major challenge as demonstrated by an unacceptable median diagnostic delay of over a year and as a result, surgery is impossible in 40% of patients...

Chronic thromboembolic pulmonary hypertension (CTEPH) is one of the potentially curable causes of pulmonary hypertension and is definitively treated with pulmonary thromboendartectomy. CTEPH can be overlooked, as its symptoms are nonspecific and can be mimicked by a wide range of diseases that can cause pulmonary hypertension. Early diagnosis of CTEPH and prompt evaluation for surgical candidacy are paramount factors in determining future outcomes. Imaging plays a central role in the diagnosis of CTEPH and patient selection for pulmonary thromboendartectomy and balloon pulmonary angioplasty...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease characterized by chronic obstructive thrombus and pulmonary hypertension. Balloon pulmonary angioplasty (BPA), an emerging alternative catheter-based treatment for inoperable patients with CTEPH, has not yet been standardised, especially for lesion assessment in distal pulmonary arteries. Recent advancement in computed tomography enables distal CTEPH lesions to be visualized. METHODS: We retrospectively studied 80 consecutive patients with inoperable CTEPH who received BPA guided by cone-beam computed tomography (CT) (CBCT) or electrocardiogram (ECG)-gated area detector CT (ADCT) for target lesion assessment...

: Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are subgroups of pulmonary hypertension and are considered rare diseases. Understanding how endpoints of clinical trials (and patient registry studies) of patients with PAH and CTEPH are associated with patient outcomes is important in order to address the concerns of patients, health care providers, decision makers, and payers. The purpose of this review was to examine how endpoints used in clinical trials and patient registry studies are associated with outcomes of patients with PAH and CTEPH...

Pulmonary endarterectomy (PEA) due to chronic thromboembolic pulmonary hypertension (CTEPH) is mainly performed in deep hypothermic circulatory arrest without additional cerebroprotective means. A 49-year-old man was treated by PEA for CTEPH by using selective antegrade cerebral perfusion by advancing the tip of the systemic perfusion cannula into the brachiocephalic trunk. The postoperative course was uneventful.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but life-threatening form of pulmonary artery hypertension that is defined as a mean arterial pulmonary pressure greater than 25mmHg that persists for more than 6 months following anticoagulation therapy in the setting of pulmonary emboli. CTEPH is categorized by the World Health Organization as group IV pulmonary hypertension and is thought to be due to unresolved thromboemboli in the pulmonary artery circulation. Among the 5 classes of pulmonary hypertension, CTEPH is unique in that it is potentially curable with the use of pulmonary thromboendarterectomy surgery...

Chronic thromboembolic pulmonary hypertension (CTEPH) is an important differential diagnosis in patients with unexplained dyspnoea. CTEPH is under-recognized and carries a poor prognosis without treatment. Surgical pulmonary endarterectomy is the preferred treatment for the majority of patients. Advances in surgical and anaesthetic techniques and post-operative intensive treatment have reduced perioperative morbidity and mortality. Pulmonary endarterectomy results in major improvement of haemodynamics and clinical status and offers excellent long-term survival...

Chronic thromboembolic pulmonary hypertension (CTEPH) represents a unique subtype of pulmonary hypertension characterized by the presence of mechanical obstruction of the major pulmonary vessels caused by venous thromboembolism. CTEPH is a progressive and devastating disease if not treated, and is the only subset of PH potentially curable by a surgical procedure known as pulmonary endarterectomy. The clot burden and pulmonary embolism recurrence may contribute to the development of CTEPH however only few thrombophilic factors have been found to be associated...

Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by formation of chronic, organized thrombus in pulmonary arteries resulting in development of pulmonary hypertension. We describe the favorable recovery of a patient with inoperable CTEPH treated with combination riociguat and inhaled treprostinil. The patient is a 77 year old female who presented with bilateral pulmonary emboli and was anticoagulated with warfarin for six months. One year later the patient developed recurrent dyspnea and multiple bilateral pulmonary emboli were again noted...

BACKGROUND: Endothelial dysfunction is key in the development of pulmonary hypertension (PH) and is associated with reduced number of circulating progenitor cells. Studies to date evaluating levels of circulating progenitor cells in PH have provided conflicting results. Current treatment of pulmonary arterial hypertension (PAH) and medical treatment of chronic thromboembolic pulmonary hypertension (CTEPH) targets endothelium dependent signalling pathways. The effect of PAH-targeted therapy on circulating progenitor cells has not been clearly established...
