Vasoreactive testing prevalence and characteristics in patients with idiopathic pulmonary arterial hypertension.

Introduction: The choice of treatment strategy in patients with idiopathic pulmonary arterial hypertension (IPAH)/HPAH/DPAH (Hereditary pulmonary arterial hypertension/ Drug-induced pulmonary arterial hypertension) II-III functional class (FC) (WHO) based on an acute vasoreactive testing result (VRT). Positive VRT (VRT+) is an indication for calcium channel blockers therapy. Long-term vasoresponders demonstrate sustained low-risk status and the highest survival among all PH subtypes.

PET/CT Imaging of the Right Heart Perfusion and Glucose Metabolism Depending on a Risk Status in Patients With Idiopathic Pulmonary Arterial Hypertension.

Right ventricular heart failure (RV HF) is the leading cause of death in pulmonary arterial hypertension (PAH). Relevance of the low-risk status assessment using available diagnostic tools requires a reliable confirmation. The study aimed to evaluate right ventricular perfusion and glucose metabolism using positron emission tomography (PET)/computed tomography (CT) with [13N]-ammonia and [18F]-fluorodeoxyglucose ([18F]-FDG) in 30 IPAH patients (33.

[Management Strategy for Patients With Idiopathic Recurrent Pericarditis. Position Statement of the Experts of the Russian Society оf Cardiology and Eurasian Association of Therapists].

Pericarditis as an inflammatory heart disease is rarely discussed in the cardiology community. The latest European guidelines on pericarditis were published in 2015, and Russian clinical guidelines are dated 2022. However, in recent years, a number of publications have appeared that have forced the scientific community to take a fresh look at this problem.

[Long-term goflkicept therapy for patients with idiopathic recurrent pericarditis: results of the interim analysis of an ongoing open-label extension study].

Aim: To evaluate the long-term safety and efficacy of goflkicept treatment in patients with idiopathic recurrent pericarditis (IRP).

Materials And Methods: This report presents the interim analysis of an ongoing open-label extension (OLE) clinical trial of goflkicept in patients with IRP (NCT05673902), as a continuation of the core study (NCT04692766). The study assessed the frequency of pericarditis recurrence, time to recurrence after 12 and 60 weeks of goflkicept therapy, changes in C-reactive protein level, chest pain intensity, pericardial effusion size, and adverse events (AEs).

Examining transfer of TERT to mitochondria under oxidative stress.

The primary role of telomerase is the lengthening of telomeres. Nonetheless, emerging evidence highlights additional functions of telomerase outside of the nucleus. Specifically, its catalytic subunit, TERT (Telomerase Reverse Transcriptase), is detected in the cytosol and mitochondria.
