Circular RNAs in atrial fibrillation: From bioinformatics analysis of circRNA-miRNA-mRNA network to serum expression.

Atrial fibrillation (AF) is a common arrhythmia in clinical practice, and its incidence is increasing year by year, which seriously affects the survival and prognosis of patients. In recent years, circRNAs has played an important role in the diagnosis and treatment of AF. The purpose of this study was to search for differentially expressed circRNAs(DEcircRNAs) in the serum of AF patients by analyzing the expression profile of existing chips, combining bioinformatics technology and in vitro experiments, and to explore the regulatory mechanism of circRNAs in the occurrence and development of AF.

The prognostic value of systemic vascular resistance in heart failure patients with permanent atrial fibrillation: a retrospective study.

Heart failure (HF) and permanent atrial fibrillation (AF) interact mutually, exacerbating hemodynamic effects and causing adverse outcomes and increased healthcare costs. Monitoring hemodynamic indicators in patients with these comorbidities is crucial for effective clinical management. Transthoracic impedance cardiography (ICG) has been widely employed in assessing hemodynamic status in clinical settings.

Research progress of non-coding RNA in atrial fibrillation.

Atrial fibrillation (AF) is a common arrhythmia in clinic, and its incidence is increasing year by year. In today's increasingly prevalent society, ageing poses a huge challenge to global healthcare systems. AF not only affects patients' quality of life, but also causes thrombosis, heart failure and other complications in severe cases.

The Relationship between Interleukin-6 Promotor Polymorphisms and Slow Coronary Flow Phenomenon.

Background: Several lines of evidence suggest that slow coronary flow (SCF) phenomenon seems to be an early form of atherosclerosis and low-grade inflammation plays a role in the development of SCF. Interleukin-6 (IL-6) is a pleiotropic cytokine, functions as a mediator of inflammatory response, and has both pro-inflammatory and anti-inflammatory properties. The aim of the present study is to investigate the relationship between IL-6 -634C/G polymorphism and SCF in Han Chinese.
