Prognostic relevance of exercise pulmonary hypertension: results of the multicentre PEX-NET Clinical Research Collaboration.

Background: Exercise pulmonary hypertension (PH) was defined by a mean pulmonary arterial pressure (mPAP)/cardiac output (CO) slope >3 mmHg·min·L between rest and exercise in the 2022 European Society of Cardiology/European Respiratory Society PH guidelines. However, large, multicentre studies on the prognostic relevance of exercise haemodynamics and its added value to resting haemodynamics are missing.

Patients And Methods: The PEX-NET (Pulmonary Haemodynamics during Exercise Network) registry enrolled patients who underwent clinically indicated right heart catheterisations both at rest and ergometer exercise from 23 PH centres worldwide.

Clinical trial design, end-points, and emerging therapies in pulmonary arterial hypertension.

Clinical trials in pulmonary arterial hypertension (PAH) have led to the approval of several effective treatments that improve symptoms, exercise capacity and clinical outcomes. In phase 3 clinical trials, primary end-points must reflect how a patient "feels, functions or survives". In a rare disease like PAH, with an ever-growing number of treatment options and numerous candidate therapies being studied, future clinical trials are now faced with challenges related to sample size requirements, efficiency and demonstration of incremental benefit on traditional end-points in patients receiving background therapy with multiple drugs.

Temporal implementation of a regional referral pathway in transthyretin cardiac amyloidosis: Emilia-Romagna experience.

Aims: Transthyretin cardiac amyloidosis (ATTR-CA) is a rare and progressive cardiomyopathy caused by amyloid fibril deposition in myocardial tissue. Diagnostic challenges have historically hampered timely detection. Recent advances in noninvasive diagnostic techniques have facilitated ATTR-CA diagnosis.

Initial combination therapy with macitentan and tadalafil in patients with pulmonary arterial hypertension, with and without cardiac comorbidities.

This prospective real-world study was designed to provide the first in-depth clinical data on the effectiveness of patisiran in patients with ATTRv reporting the p.Ile88Leu variant, the most widespread variant in the Emilia-Romagna regional area, which has been less represented in previous clinical trials.

Off-Label Use of Balloon-Expandable Transcatheter Valves to Treat Pure Aortic Regurgitation.

Transcatheter aortic valve implantation (TAVI) in native pure aortic regurgitation (AR) with off-label use of balloon-expandable valves (BEV) has been reported. However, there are scant data regarding optimal oversizing and its safety, and our study assessed BEV oversizing and outcomes of TAVI. Thirteen consecutive tricuspid aortic valve patients who underwent transfemoral TAVIs for pure AR with Sapien BEV at our center between 2019 and 2023 (69.

[ANMCO/SIC Consensus statement on pulmonary arterial hypertension].

Pulmonary hypertension (PH) is a frequent pathological condition worldwide, mainly secondary to cardiovascular and respiratory diseases, with a poor prognosis. Pulmonary arterial hypertension (PAH) is a rare form that affects the arterial pulmonary vasculature. PH and PAH are characterized by non-specific symptoms and a progressive increase of pulmonary vascular resistance that results in progressive, sometimes irreversible, right ventricular dysfunction.

Comparison of cardiac magnetic resonance imaging, functional and haemodynamic variables in pulmonary arterial hypertension: insights from REPAIR.

Background: Measures that can detect large treatment effects are important for monitoring therapeutic effectiveness. The 2022 European Society of Cardiology/European Respiratory Society guidelines highlight the importance of imaging in monitoring disease status and treatment response in pulmonary arterial hypertension (PAH). Are the standardised treatment effect sizes (STES) of cardiac magnetic resonance imaging (cMRI) comparable with functional and haemodynamic variables?

Methods: REPAIR (ClinicalTrials.

Effect of Macitentan in Pulmonary Arterial Hypertension and the Relationship Between Echocardiography and cMRI Variables: REPAIR Echocardiography Sub-study Results.

Introduction: The aim of this sub-study was to evaluate the relationship between echocardiography (echo) and cardiac magnetic resonance imaging (cMRI) variables and to utilize echo to assess the effect of macitentan on right ventricle (RV) structure and function.

Methods: REPAIR (NCT02310672) was a prospective, multicenter, single-arm, open-label, 52-week, phase 4 study in pulmonary arterial hypertension (PAH) patients, which investigated the effect of macitentan 10 mg as monotherapy, or in combination with a phosphodiesterase 5 inhibitor, on RV structure, function, and hemodynamics using cMRI and right heart catheterization. In this sub-study, patients were also assessed by echo at screening and at weeks 26 and/or 52.

Comparison of different treatment strategies in patients with chronic thromboembolic pulmonary hypertension: a single centre real-world experience.

Background: Pulmonary endarterectomy (PEA) has been the most effective therapy for chronic thromboembolic pulmonary hypertension (CTEPH). However, there is a substantial proportion of patients deemed not operable in whom other treatment strategies are available: medical therapy and balloon pulmonary angioplasty (BPA). We aimed to compare different CTEPH treatment strategies effect in a real-world setting.

Prognostic Role of Early Cardiac Magnetic Resonance in Myocardial Infarction With Nonobstructive Coronary Arteries.
