Aims: To systematically assess late outcomes of acute pulmonary embolism (PE) and to investigate the clinical implications of post-PE impairment (PPEI) fulfilling prospectively defined criteria.

Methods And Results: A prospective multicentre observational cohort study was conducted in 17 large-volume centres across Germany. Adult consecutive patients with confirmed acute symptomatic PE were followed with a standardized assessment plan and pre-defined visits at 3, 12, and 24 months.

Quality of Life 3 and 12 Months Following Acute Pulmonary Embolism: Analysis From a Prospective Multicenter Cohort Study.

Background: Few data are available on the long-term course and predictors of quality of life (QoL) following acute pulmonary embolism (PE).

Research Question: What are the kinetics and determinants of disease-specific and generic health-related QoL 3 and 12 months following an acute PE?

Study Design And Methods: The Follow-up after Acute Pulmonary Embolism (FOCUS) study prospectively followed up consecutive adult patients with objectively diagnosed PE. Patients were considered for study who completed the Pulmonary Embolism Quality of Life (PEmb-QoL) questionnaire at predefined visits 3 and 12 months following PE.

Risk stratification strategy and assessment of disease progression in patients with pulmonary arterial hypertension: Updated Recommendations from the Cologne Consensus Conference 2018.

In the summer of 2016, delegates from the German Respiratory Society, the German Society of Cardiology and the German Society of Pediatric Cardiology met in Cologne, Germany, to define consensus-based practice recommendations for the management of patients with pulmonary arterial hypertension (PAH). These recommendations were built on the 2015 European Pulmonary Hypertension guidelines and included new evidence, where available, and were last updated in the spring of 2018. This article focusses on the proposed risk stratification and assessment of disease progression in patients with pulmonary arterial hypertension (PAH), covering 3 parts: In part 1, methods and markers that are recommended to assess severity and progression of PAH are discussed and commented.

Late outcomes after acute pulmonary embolism: rationale and design of FOCUS, a prospective observational multicenter cohort study.

Acute pulmonary embolism (PE) is a frequent cause of death and serious disability. The risk of PE-associated mortality and morbidity extends far beyond the acute phase of the disease. In earlier follow-up studies, as many as 30 % of the patients died during a follow-up period of up to 3 years, and up to 50 % of patients continued to complain of dyspnea and/or poor physical performance 6 months to 3 years after the index event.

Self-Report Daily Life Activity as a Prognostic Marker of Idiopathic Pulmonary Fibrosis.

Background: Idiopathic pulmonary fibrosis (IPF) is a progressive disease, leading to substantial physical impairment. The distance walked in 6 min (6MWD) is a measure of exercise tolerance and is of prognostic relevance in IPF. While 6MWD is a punctual measurement which may not be representative, self-reported daily life activity may represent the patients' functional capacity more globally even in less severe affected patients.

Residual pulmonary vasodilative reserve predicts outcome in idiopathic pulmonary hypertension.

Objective: Idiopathic pulmonary arterial hypertension (IPAH) remains a devastating and incurable, albeit treatable condition. Treatment response is not uniform and parameters that help to anticipate a rather benign or a malignant course of the disease are warranted. Acute pulmonary vasoreactivity testing during right heart catheterisation is recommended to identify a minority of patients with IPAH with sustained response to calcium channel blocker therapy.

[Treatment goals of pulmonary hypertension].

With significant therapeutic advances in the field of pulmonary arterial hypertension, the need to identify clinically relevant treatment goals that correlate with long-term outcome has emerged as 1 of the most critical tasks. Current goals include achieving modified New York Heart Association functional class I or II, 6-min walk distance >380 m, normalization of right ventricular size and function on echocardiograph, a decreasing or normalization of B-type natriuretic peptide (BNP), and hemodynamics with right atrial pressure <8 mm Hg and cardiac index >2.5 L/dk/m2.

Augmentation of the effects of vasoactive intestinal peptide aerosol on pulmonary hypertension via coapplication of a neutral endopeptidase 24.11 inhibitor.

A deficiency of the pulmonary vasodilative vasoactive intestinal peptide (VIP) has been suggested to be involved in the pathophysiology of pulmonary hypertension (PH). Supplementation of VIP as an aerosol is hampered by the fact that it is rapidly inactivated by neutral endopeptidases (NEP) located on the lung surface. Coapplication of thiorphan, an NEP 24.

Haemodynamic changes in pulmonary hypertension in patients with interstitial lung disease treated with PDE-5 inhibitors.

Background And Objective: Interstitial lung diseases (ILD) are often associated with pulmonary hypertension (PH). This study aimed to evaluate the therapeutic benefit of phosphodiesterase-5 (PDE-5) inhibitors in pulmonary hypertension secondary to ILD.

Methods: Patients with ILD and PH were treated with sildenafil or tadalafil.

Treatment goals of pulmonary hypertension.

With significant therapeutic advances in the field of pulmonary arterial hypertension, the need to identify clinically relevant treatment goals that correlate with long-term outcome has emerged as 1 of the most critical tasks. Current goals include achieving modified New York Heart Association functional class I or II, 6-min walk distance >380 m, normalization of right ventricular size and function on echocardiograph, a decreasing or normalization of B-type natriuretic peptide (BNP), and hemodynamics with right atrial pressure <8 mm Hg and cardiac index >2.5 mg/kg/min(2).

Acute hemodynamic responses to supplemental oxygen and their prognostic implications in pulmonary hypertension.

Background: Pulmonary hypertension (PH) of various causes leads to a poor prognosis. Pulmonary vasoreactivity testing during right heart catheterization (RHC) has prognostic and therapeutic consequences.

Objective: To characterize the acute hemodynamic response to short-term oxygen supplementation (SHOT) in adult PH patients and its impact on prognosis.

The potential of biomarkers in pulmonary arterial hypertension.

Effective management of patients with pulmonary arterial hypertension (PAH) requires comprehensive prognostic evaluation in order to determine optimal management strategies. Although a number of clinical and hemodynamic parameters linked to PAH prognosis have been identified, some are associated with significant limitations (eg, invasive techniques, subjective measures). There is a need for noninvasive and objective measures to be established that function as biomarkers for the diagnosis and assessment of disease prognosis, and that determine response to therapy in patients with PAH.

Riociguat for interstitial lung disease and pulmonary hypertension: a pilot trial.

We assessed the safety, tolerability and preliminary efficacy of riociguat, a soluble guanylate cyclase stimulator, in patients with pulmonary hypertension associated with interstitial lung disease (PH-ILD). In this open-label, uncontrolled pilot trial, patients received oral riociguat (1.0-2.

Non-invasive diagnosis of pulmonary hypertension: ESC/ERS Guidelines with Updated Commentary of the Cologne Consensus Conference 2011.

The 2009 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension have been adopted for Germany. The guidelines contain detailed recommendations for the diagnosis of pulmonary hypertension. However, the practical implementation of the European Guidelines in Germany requires the consideration of several country-specific issues and already existing novel data.

Preserved pulmonary vasodilative properties of aerosolized brain natriuretic peptide.

Introduction: Inhalation of vasoactive substances is an effective treatment of pulmonary hypertension. The B-type natriuretic peptide (BNP) leads to relaxation of smooth muscle cells, caused by an increased formation of cyclic guanosine monophosphate (cGMP). The biologic activity of BNP using an inhalative approach has not been addressed.

Inhalation of endothelin receptor blockers in pulmonary hypertension.

Endothelin 1 (ET-1) is a potent pulmonary vasoconstrictor and mediator of lung diseases. Antagonism of the ET-1-mediated effects has become an important therapeutic approach. ET-1 (A and B) receptors are differentially distributed in the lung vasculature.

N-terminal pro-brain natriuretic peptide and renal insufficiency as predictors of mortality in pulmonary hypertension.

Background: N-terminal pro-brain natriuretic peptide (NT-proBNP) is a byproduct of the brain natriuretic peptide (BNP) that was shown to be of prognostic value in pulmonary hypertension (PH). The role of NT-proBNP in PH has to be determined, especially under the influence of renal impairment that might lead to an accumulation of the peptide, and may be a sign of increased mortality per se.

Methods: We assessed NT-proBNP, BNP, renal function, and hemodynamic parameters (during right-heart catheterization) in 118 consecutive patients with isolated PH, excluding left-heart disease.

Brain natriuretic peptide is a prognostic parameter in chronic lung disease.

Rationale: The detection of pulmonary hypertension in patients with chronic lung disease has prognostic implications. The brain natriuretic peptide (BNP) has been suggested as a noninvasive marker for the presence and severity of pulmonary hypertension.

Objectives: We evaluated circulating BNP levels as a parameter for the presence and severity of pulmonary hypertension in patients with chronic lung disease.

Characterization of brain natriuretic peptide in long-term follow-up of pulmonary arterial hypertension.

Study Objectives: Pulmonary arterial hypertension (PAH) leads to substantial morbidity and mortality. Noninvasive parameters in the follow-up assessment of PAH could be helpful in clinical decision making. The brain natriuretic peptide (BNP) has been shown to correlate with the functional status and prognosis of these patients and could be a valuable parameter in this respect.

Iloprost for idiopathic pulmonary arterial hypertension.

Idiopathic pulmonary arterial hypertension is a rare but serious and life-threatening disease that leads to right heart failure and death within 2.8 years without specific treatment. This review focuses on the stable prostacyclin analog iloprost, its biologic action and pharmacology and, finally, on its clinical development, efficacy and safety in patients with idiopathic pulmonary arterial hypertension, which led to its approval for this indication.

Brain natriuretic peptide and exercise capacity in lung fibrosis and pulmonary hypertension.

Pulmonary hypertension (PH) can develop in lung fibrosis, and contributes to increased morbidity and mortality. Noninvasive parameters in the evaluation of PH in lung disease could aid in the management of these subjects. In this study, we aimed to characterize the role of brain natriuretic peptide (BNP) and the six-minute walk distance (6-MWD) in the assessment of pulmonary hypertension (PH) in subjects with lung fibrosis.

Clinical significance of brain natriuretic peptide in primary pulmonary hypertension.

Objectives: The aim of this study was to investigate the potential role of brain natriuretic peptide (BNP) levels in the assessment of functional status and right heart performance in primary pulmonary hypertension (PPH).

Background: Primary pulmonary hypertension is a progressive disease leading to right heart failure and death. Right heart catheterization and maximal or submaximal exercise tests are employed to assess the course of the disease and the effect of therapeutic interventions.

Hemodynamic response to sildenafil, nitric oxide, and iloprost in primary pulmonary hypertension.

Study Objectives: Different vasodilators and different routes of application are used for the treatment of primary pulmonary hypertension (PPH). Recently, sildenafil, a phosphodiesterase-V inhibitor, has been shown to have beneficial hemodynamic effects in PPH. However, the hemodynamic effects of sildenafil have not been characterized and compared to other vasodilators such as inhaled nitric oxide (iNO) or iloprost in PPH in the same group of patients.
