Effects of β-Blockers on the Outcomes in Patients With Pulmonary Arterial Hypertension Stratified by the Presence of Comorbid Conditions: A Multicenter Prospective Cohort Study (BNP-PL).

Background: Current guidelines do not recommend β-blockers in pulmonary arterial hypertension (PAH) unless indicated by comorbidities. However, the evidence regarding the role of β-blockers in PAH is contradictory.

Research Question: What are the effects of β-blockers on clinical outcomes in patients newly diagnosed with PAH, and how do these outcomes differ based on the presence of cardiovascular comorbidities that are standard indications for β-blocker use?

Study Design And Methods: We analyzed data from 806 patients newly diagnosed with PAH enrolled prospectively in the Database of Pulmonary Hypertension in the Polish Population (BNP-PL).

Right-ventricle heart failure in PAH vs. HFrEF with secondary PH: Hemodynamic, ergospirometric, and organ function correlations.

Purpose: The goal of the study was to identify markers of organ function used in daily routines that could potentially aid in the overall evaluation of the cardiovascular system in patients with right-ventricle heart failure due to pulmonary arterial hypertension (PAH) and left-ventricle heart failure. We analyzed correlations between parameters from right heart catheterization (RHC), cardiopulmonary exercise test (CPET), and selected laboratory parameters of thyroid, liver, kidneys function and iron homeostasis.

Patients And Methods: A retrospective analysis included 107 patients (mean age 57.

Pentraxin 3 as a marker of development and severity of stable coronary artery disease.

Purpose: Inflammation plays a crucial role in the development of atherosclerotic plaques. Pentraxin 3 (PTX3) is produced at the site of inflammation and has been identified as a specific marker of atherosclerosis, vascular inflammation, and progression of the coronary artery disease (CAD). The aim of the study was to establish if PTX3 has potential relations with classical markers of cardiovascular risk, and if PTX3 may act as an independent risk factor of CAD occurrence and advancement.
