Comprehensive exploration of unexplained dyspnoea in subjects with normal ejection fraction and low natriuretic peptides

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 879-887, April 2025.
Abstract Background Unexplained exertional dyspnoea without significant elevation of natriuretic peptides is common. One of the causes might be early heart failure with preserved ejection fraction (HFpEF). Aims This study aimed to characterize patients with exertional dyspnoea and normal/near‐to‐normal N‐terminal pro‐brain natriuretic peptide (NT ...

Sildenafil dosed concomitantly with bosentan for adult pulmonary arterial hypertension in a randomized controlled trial [PDF]

open access: yes, 2017
BACKGROUND: Few controlled clinical trials exist to support oral combination therapy in pulmonary arterial hypertension (PAH). METHODS: Patients with PAH (idiopathic [IPAH] or associated with connective tissue disease [APAH-CTD]) taking bosentan (62.5 ...

Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1029-1044, April 2025.
Abstract Cardiac remodelling is a key determinant of worse cardiovascular outcome in patients with heart failure (HF) and reduced ejection fraction (HFrEF). It affects both the left ventricle (LV) structure and function as well as the left atrium (LA) and the right ventricle (RV).

Pathogenic Role of mTORC1 and mTORC2 in Pulmonary Hypertension. [PDF]

open access: yes, 2018

Micro-RNA-1 is decreased by hypoxia and contributes to the development of pulmonary vascular remodeling via regulation of sphingosine kinase 1 [PDF]

open access: yes, 2018
Sphingosine kinase 1 (SphK1) upregulation is associated with pathologic pulmonary vascular remodeling in pulmonary arterial hypertension (PAH), but the mechanisms controlling its expression are undefined.

Epistatic interactions in idiopathic pulmonary arterial hypertension

open access: yesIndian Journal of Human Genetics, 2012
Idiopathic pulmonary arterial hypertension (IPAH) is a poorly understood complex disorder, which results in progressive remodeling of the pulmonary artery that ultimately leads to right ventricular failure. A two-hit hypothesis has been implicated in pathogenesis of IPAH, according to which the vascular abnormalities characteristic of PAH are triggered

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).

Mate-pair sequencing identifies a cryptic mutation in hereditary pulmonary arterial hypertension

open access: yesPulmonary Circulation, 2020
Current guidelines suggest screening all patients with idiopathic pulmonary arterial hypertension for genetic aberrations, particularly mutations in Bone Morphogenic Protein Receptor Type II ( BMPR2 ), the gene most commonly implicated in the ...

Non-infectious pulmonary complications of hematopoietic stem cell transplantation [PDF]

open access: yes, 2014
Noninfectious pulmonary complications of hematopoietic stem cell transplant are currently more prevalent than infectious complications. Unfortunately, the pathophysiology basis is not completely understood.
