Although measurement of right ventricular ejection fraction (RVEF) may be relevant for evaluation of therapeutic efficacy and/or prognosis in patients with pulmonary hypertension, RVEF obtained by echocardiography has limited accuracy. In contrast, radionuclide and/or magnetic resonance imaging can measure RVEF more reliably. In this study, we investigated the relationship between RVEF measured by radionuclide angiography and the echocardiographic parameters that are recommended by the American Society of Echocardiography as representative of right heart function...

BACKGROUND: For treatment of chronic thromboembolic pulmonary hypertension (CTEPH), the evaluation of segmental pulmonary perfusion is important. There are no previous reports about lung subtraction iodine mapping (LSIM) computed tomography (CT) for evaluation of segmental pulmonary perfusion in patients with CTEPH, using lung perfusion SPECT/CT (LPS) as the reference. METHODS: 50 patients (age, 60.7±16.7years) with known or suspected CTEPH were enrolled in this study...

Pulmonary hypertension (PH) is a complex disease process of the pulmonary vasculature system characterized by elevated pulmonary arterial pressures. Patients with PH are at increased risk for morbidity and mortality, including intraoperatively and postoperatively. Appreciation by the clinical anesthesiologist of the pathophysiology of PH is warranted. Careful and meticulous strategy using appropriate anesthetic medications, pulmonary vasodilator and inotropic agents, and careful fluid management all increase the likelihood of the best possible outcome in this challenging patient population...

Pulmonary hypertension is defined by a mean pulmonary artery pressure ≥25 mm Hg at rest. Management of pulmonary arterial hypertension (PAH) includes specific drug therapy with calcium channel blockers in vasoreactive patients, or drugs approved for PAH in non-reactive patients that target the endothelin, nitric-oxide and prostacyclin pathways. Areas covered: The review covers receptor selectivity, pharmacokinetics, pharmacodynamics and adverse effects (AEs) of intravenous (IV) epoprostenol (synthetic prostacyclin); the prostacyclin analogs iloprost, beraprost, and treprostinil administered by IV, subcutaneous, inhaled or oral routes; and the oral selective prostacyclin receptor agonist selexipag...

Pulmonary arterial hypertension (PAH), at one time a largely overlooked disease, is now the subject of intense study in many academic and biotech groups. The availability of new treatments has increased awareness of the condition. This in turn has driven a change in the demographics of PAH, with an increase in the mean age at diagnosis. The diagnosis of PAH in more elderly patients has highlighted the need for careful phenotyping of patients and for further studies to understand how best to manage pulmonary hypertension associated with, for example, left heart disease...

Sulfur dioxide (SO₂) is a toxic gas and air pollutant. The toxic effects of SO₂ have been extensively studied. Oxidative damage due to SO2 can occur in multiple organs. Inhaled SO₂ can also cause chromosomal aberrations, DNA damage and gene mutations in mammals. However, SO₂ can also be generated from the sulfur-containing amino acid, L-cysteine. Recent studies have shown that SO₂ has a vasorelaxant effect, and ameliorates pulmonary hypertension and vascular remodeling. SO₂ can also reduce lung injury and myocardial injury in rats...

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare clinical entity that occurs in a small subset of acute pulmonary embolism (PE) cases and is surgically cured by pulmonary endarterectomy. We report a case of a 44-year-old female with a complex history of CTEPH treated by thromboendarterectomy who presented with a subdural hematoma while on warfarin. The patient eventually recovered by a multidisciplinary approach, use of inferior vena caval filter, and effective anticoagulation management.

With rising altitude the partial pressure of oxygen falls. This phenomenon leads to hypobaric hypoxia at high altitude. Since more than 140 million people permanently live at heights above 2500 m and more than 35 million travel to these heights each year, understanding the mechanisms resulting in acute or chronic maladaptation of the human body to these circumstances is crucial. This review summarizes current knowledge of the body's acute response to these circumstances, possible complications and their treatment, and health care issues resulting from long-term exposure to high altitude...

Left ventricular assist device (LVAD) is one of the modern management therapies in patients with advanced heart failure, and it serves as a bridge to heart transplantation or even as destination therapy. However, it is burdened with a high risk of thromboembolic, hemorrhagic, and infectious complications despite prophylactic management. Splenic abscesses, as septic complications following implantation of mechanical ventricular support, have not yet been described in the literature. We report of a patient with severe left ventricular insufficiency (NYHA II/III), pulmonary hypertension, and arrhythmia who underwent implantation of the Heart Ware® pump for left ventricular support with simultaneous tricuspidvalvoplasty, as a bridge therapy to heart transplantation...

Background: Pulmonary arterial hypertension (PAH) is a rapidly degenerating and devastating disease of increased pulmonary vessel resistance leading to right heart failure. Palliative modalities remain limited despite recent endeavors to investigate the mechanisms underlying increased pulmonary vascular resistance, i.e. aberrant vascular remodeling and occlusion. However, little is known of the molecular mechanisms responsible for endothelial proliferation, a root cause of PAH-associated vascular remodeling...

Pulmonary hypertension (PH) is a progressive disorder whose cellular pathogenesis involves enhanced smooth muscle cell (SMC) proliferation and resistance to apoptosis signals. Existing evidence demonstrates that the tumor suppressor, programmed cell death 4 (PDCD4) affects patterns of cell growth and repair responses in the systemic vasculature following experimental injury. In the current study, the regulation PDCD4 and its functional effects on growth and apoptosis susceptibility in pulmonary artery smooth muscle cells was explored...

As the prevalence of morbid obesity increased in Korea, the estimation of the accurate socioeconomic costs by morbid obesity was required; we analysed national medical costs through the big data. From 2009 year to 2013 year, Direct Costs (DC) for medical costs, transit costs and nursing costs and Indirect Costs (IC) for Future Income Loss (FIL) and Productivity Loss (PL) of morbid obesity (BMI≥30) were calculated, and socioeconomic costs were estimated by applying Population Attributable Risk (PAR) proportion according to obesity related diseases...

Mazindol is an imidazo-isoindole derivative, a tricyclic compound and a non-amphetamine central nervous system stimulant that blocks dopamine and norepinephrine reuptake. Mazindol was withdrawn from the US and European markets in 1999 for reasons unrelated to its efficacy or safety around a time when other anorexic drugs were found to be associated with the development of pulmonary arterial hypertension (PAH). Despite the use of mazindol for decades, reports of PAH due to mazindol intake have been extremely rare...

Systemic sclerosis (SSc) is an autoimmune disease characterized by vascular dysfunction and excessive fibrosis, involving internal organs including the heart. The estimated prevalence of cardiac involvement in SSc is high and remains subclinical until the late stages. It is either primary, related to myocardial inflammation and fibrosis, or secondary, due to pulmonary arterial hypertension (SSc-PAH) or systemic hypertension, in those patients with renal involvement. Cardiovascular magnetic resonance (CMR) is a useful tool for the early assessment of cardiac involvement in SSc...

Pulmonary hypertension (PH) in neonates, infants, children, adolescents, and young adults is a complex condition that can be associated with several cardiac, pulmonary, and systemic diseases contributing to morbidity and mortality. The underlying pulmonary hypertensive vascular disease (PHVD) is characterized by inflammation, pulmonary vascular remodeling, and angio-obliteration leading to elevated pulmonary arterial pressure and resistance, right ventricular dysfunction, left ventricular compression, and subsequent heart failure...
