Acta Cardiol 2022 Aug 10:1-8. Epub 2022 Aug 10.

Research Group on Heart Failure, IIS Aragón, Zaragoza, Spain.

Background: We aimed to characterise and compare the clinical profile of heart failure (HF) with mid-range (HFmrEF), reduced (HFrEF) and preserved (HFpEF) left-ventricular ejection fraction.

An explorative metabolomic analysis of the endothelium in pulmonary hypertension.

Sci Rep 2022 Aug 2;12(1):13284. Epub 2022 Aug 2.

Department of Clinical Immunology, Copenhagen University Hospital, Rigshospitalet, Copenhagen, Denmark.

Pulmonary hypertension (PH) is classified into five clinical diagnostic groups, including group 1 [idiopathic pulmonary arterial hypertension (IPAH) and connective tissue disease-associated PAH (CTD-aPAH)] and group 4 (chronic thromboembolic pulmonary hypertension (CTEPH)). PH is a progressive, life-threatening, incurable disease. The pathological mechanisms underlying PH remain elusive; recent evidence has revealed that abnormal metabolic activities in the endothelium may play a crucial role. Read More

Prognostic Implications of the Novel Pulmonary Hypertension Definition in Patients with Aortic Stenosis after Transcatheter Valve Replacement.

J Clin Med 2022 Jul 22;11(15). Epub 2022 Jul 22.

Faculty of Medicine, Department of Medicine, Geneva University, 1206 Geneva, Switzerland.

: Pulmonary hypertension (PH), traditionally defined as a mean pulmonary artery pressure (PAP) ≥ 25 mmHg, is associated with poor outcomes in patients undergoing a transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS). Recently, a novel definition for PH has been proposed, placing the cut-off value of mean PAP at 20 mmHg, and introducing pulmonary vascular resistance as an exclusive indicator for the pre-capillary involvement. In light of the novel criteria, whether PH still preserves its prognostic significance remains unknown. Read More

J Cardiovasc Pharmacol 2022 Jul 12. Epub 2022 Jul 12.

Pediatrics Departments, Faculty of Medicine, Ain Shams University, Cairo, Egypt.

Abstract: Persistent pulmonary hypertension (PPHN) is a condition caused by failure of pulmonary vascular adaptation at birth, resulting in severe hypoxia. Several therapeutic modalities are being tried in developing countries where established therapies (inhaled nitric oxide [iNO] and extracorporeal membrane oxygenation [ECMO]) are widely unavailable. This study aimed to assess the efficacy of milrinone versus sildenafil as available alternative therapeutics in treating PPHN. Read More

Assessment of Clinical Worsening End Points as a Surrogate for Mortality in Pulmonary Arterial Hypertension: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Circulation 2022 Jul 8:101161CIRCULATIONAHA121058635. Epub 2022 Jul 8.

Institut Universitaire de Cardiologie et de Pneumologie de Québec Research Center, Université Laval, Quebec City, Canada. (E.T., C.G., V.M., A.C.L., Y.L., S.B., S.P.).

All Roads Lead to Rome: Diverse Etiologies of Tricuspid Regurgitation Create a Predictable Constellation of Right Ventricular Shape Changes.

Front Physiol 2022 2;13:908552. Epub 2022 Jun 2.

St. Luke's Medical Center Cardiothoracic and Vascular Surgery, Boise, ID, United States.

Myriad disorders cause right ventricular (RV) dilation and lead to tricuspid regurgitation (TR). Because the thin-walled, flexible RV is mechanically coupled to the pulmonary circulation and the left ventricular septum, it distorts with any disturbance in the cardiopulmonary system. TR, therefore, can result from pulmonary hypertension, left heart failure, or intrinsic RV dysfunction; but once it occurs, TR initiates a cycle of worsening RV volume overload, potentially progressing to right heart failure.
