BACKGROUND: Unilateral absence of the pulmonary artery (UAPA) is a rare congenital malformation often associated with other cardiac anomalies; however it may occur as an isolated lesion. Isolated absence of the right pulmonary artery is twice more frequent than that of the left pulmonary artery. Patients with isolated UAPA are usually asymptomatic at birth; thereafter they may develop a progression of symptoms such as exercise intolerance, dyspnea, chest pain, hemoptysis and recurrent pulmonary infections...

We present here the case of a 30-year-old man with a long term history of nephrotic syndrome (NS) who developed an episode of acute left main pulmonary artery thrombosis complicated by a lung abscess. During the hospital admission was also identified a concomitant hyperhomocysteinemia. After an atypical resection of the left upper pulmonary lobe and the starting of long term anticoagulation the patient was discharged but did not attend the planned follow up visits until one year later when he was seen again for severe dyspnea and exercise intolerance...

Background: Sex differences in chronic thromboembolic pulmonary hypertension (CTEPH) have been revealed in few studies. Although right heart catheterization (RHC) is the gold standard for clinical diagnosis and assessment of prognosis in pulmonary hypertension (PH), cardiopulmonary exercise testing (CPET) has been a more widely used assessment of functional capacity, disease severity, prognosis, and treatment response in PH. We hypothesized that the "sex-specific" CPET indices could estimate the severity of inoperable CTEPH...

BACKGROUND: Studies have shown that peak circulatory power (peak CircP; peak oxygen uptake × peak systolic blood pressure) is a variable predictor of prognosis in patients with left heart failure. It remains unknown whether peak CircP also predicts outcome in patients with idiopathic pulmonary arterial hypertension (IPAH). METHODS: Patients with newly diagnosed IPAH who underwent symptom-limited cardiopulmonary exercise testing (CPET) from 1 January 2011 to 1 January 2014 in Fuwai Hospital were prospectively enrolled and followed for up to 66 months for cardiac events (mortality and lung transplantation)...

Pulmonary arterial hypertension (PAH) is a devastating disease characterized by progressive increases in pulmonary vascular resistance that can ultimately lead to right ventricle failure and death. Common symptoms include shortness of breath, fatigue, dizziness and chest pain, which negatively impact the functional capacity and quality of life. Despite the improvements in disease-targeted therapies, PAH remains incurable and with a high mortality rate, requiring effective therapeutic strategies. Exercise training is an important adjunct non-pharmacological treatment for patients with left heart failure and chronic obstructive pulmonary disease...

BACKGROUND: In heart failure (HF), a flattening oxygen consumption (VO2 ) trajectory during cardiopulmonary exercise test (CPET) reflects an acutely compromised cardiac output. We hypothesized that a flattening VO2 trajectory is helpful in phenotyping disease severity and prognosis in HF with either reduced (HFrEF), mid-range (HFmrEF), or preserved (HFpEF) ejection fraction. METHODS AND RESULTS: Overall, 319 HF patients (198 HFrEF, 80 HFmrEF, and 41 HFpEF) underwent CPET...

Pulmonary hypertension (PH) is a progressive and often fatal illness presenting with nonspecific symptoms of dyspnea, lower extremity edema, and exercise intolerance. Pathologically, endothelial dysfunction leads to abnormal intimal and smooth muscle proliferation along with reduced apoptosis, resulting in increased pulmonary vascular resistance (PVR) and elevated pulmonary pressures. PH is subdivided into five WHO groups based on the disease pathology and specific cause. While there are FDA-approved medications for the treatment of pulmonary arterial hypertension (PAH, Group 1 PH), as well as for chronic thromboembolic pulmonary hypertension (CTEPH, Group 4 PH), the morbidity and mortality remain high...

Exercise stress testing of the pulmonary circulation for the diagnosis of latent or early stage pulmonary hypertension is gaining acceptance. There is emerging consensus to define exercise-induced pulmonary hypertension by a mean pulmonary artery pressure higher than 30 mmHg at a cardiac output of less than 10 L/min and a total pulmonary vascular resistance higher than 3 Wood units at maximum exercise, in the absence of pulmonary hypertension at rest. Exercise-induced pulmonary hypertension has been reported in association with a bone morphogenetic receptor-2 gene mutation, in systemic sclerosis, in left heart conditions, in chronic lung diseases and in chronic pulmonary thrombo-embolism...

The benefits of exercise training in virtually all humans, including those with a clinically stable chronic disease are numerous. The potential value lies in the fact that functional capacity is oftentimes significantly compromised. Exercise training not only play a role in reversing some of the pathophysiologic processes associated with chronic diseases but also improves clinical trajectory. Given the significant pathologic consequences associated with pulmonary hypertension and its implications for deteriorating right ventricular function as well as the perceived potential for a precipitous and possibly critical drop in cardiac output during periods of physical exertion, exercise training was historically not recommended for these patients...

BACKGROUND: Right ventricular function is the major determinant of morbidity and mortality in pulmonary arterial hypertension (PAH). The ESC risk assessment strategy for PAH is based on clinical status, exercise testing, NTproBNP, imaging and haemodynamics but does not include right ventricular function. Our aims were to test the power of resting echocardiographic measurements to classify PAH patients according to ESC exercise testing risk stratification cut-offs and to determine if the classification power of echocardiographic parameters varied in chronic thrombo-embolic pulmonary hypertension (CTEPH)...

Background -Patients with systemic sclerosis-associated pulmonary arterial hypertension (SSc-PAH) have a far worse prognosis than those with idiopathic PAH (IPAH). In the intact heart, SSc-PAH exhibits depressed rest and reserve right ventricular (RV) contractility as compared to IPAH. We tested whether this disparity involves underlying differences in myofilament function. Methods -Cardiac myocytes were isolated from RV septal endomyocardial biopsies from patients with SSc-PAH, IPAH, or SSc with exertional dyspnea but no resting PAH (SSc-d); control RV septal tissue was obtained from non-diseased donor hearts (6-7/group)...

Background: Exercise tolerance decreases as COPD progresses. Pulmonary hypertension (PH) is common in COPD and may reduce performance further. COPD patients with and without PH could potentially be identified by cardiopulmonary exercise test (CPET). However, results from previous studies are diverging, and a unified conclusion is missing. We hypothesized that CPET combined with arterial blood gases is useful to discriminate between COPD outpatients with and without PH. Methods: In total, 93 COPD patients were prospectively included...

Chronic thromboembolic pulmonary hypertension (CTEPH) has a poor prognosis because of the associated progressive right heart failure. Accurate evaluation of right ventricular (RV) function would thus be useful to predict prognosis. However, the significance of RV diastolic function remains unclear. We aimed to identify which echocardiographic measures are most accurate, and potentially useful, in assessing RV diastolic function in patients with CTEPH, and to study the effects of balloon pulmonary angioplasty (BPA) on them...

SERAPHIN was a double-blind, placebo-controlled, event-driven phase III trial that evaluated the effects of long-term treatment with macitentan, an oral endothelin receptor antagonist, in patients with pulmonary arterial hypertension (PAH). The majority of patients were receiving PAH therapy at enrollment, providing the opportunity to evaluate the efficacy and safety of macitentan in combination with other PAH therapies (predominantly phosphodiesterase type 5 inhibitors [PDE-5i]). In patients receiving background therapy, macitentan reduced the risk of morbidity/mortality by 38% compared with placebo (hazard ratio [HR] 0...

PURPOSE: Pulmonary hypertension (PH) in the setting of parenchymal lung disease adversely affects quality of life and survival. However, PH-specific drugs may result in ventilation/perfusion imbalance and currently, there are no approved PH treatments for this patient population. In the present retrospective study, data from 22 patients with PH associated with lung disease treated with inhaled treprostinil (iTre) and followed up clinically for at least 3 months are presented. METHODS: PH was defined by resting right heart catheterization as a mean pulmonary artery pressure (mPAP) ≥ 35 mmHg, or mPAP ≥ 25 mmHg associated with pulmonary vascular resistance ≥ 4 Woods Units...

PURPOSE: Assessment of balance performance is important for both diagnostic and therapeutic reasons in clinical practice. Although the ideal exercise prescription is unknown for patients with pulmonary arterial hypertension (PAH), balance training may be effective for this population if they have balance impairments, such as other patients with cardiopulmonary diseases. The present study aimed to evaluate static and dynamic balance performance and balance confidence in individuals with and without PAH...
