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).

Expression of Acidic Fibrillar Protein and Neuroglobin in Thrombolytic Patients in Ischemic Stroke.

Purpose: Glial fibrillary acidic protein (GFAP) and neuroglobin (NGB) are important biomarkers of cerebral hypoxia. For this reason, an attempt was made to assess their concentrations in various time intervals and their impact on the severity of neurological symptoms and functional prognosis of thrombolytic ischemic stroke patients.

Patients And Methods: The study involved 94 patients reporting to the emergency department of the Collegium Medicum University Hospital in Bydgoszcz within < 4.
