Obstructive sleep apnea and atrial fibrillation: insights from a bidirectional Mendelian randomization study

BMC Medical Genomics, 2022
Background Observational studies have suggested that obstructive sleep apnea (OSA) is in relation to atrial fibrillation (AF); however, these studies might be confounded and whether the relationship is causal remains unclear. We conducted a bidirectional

Genetic Determinants of Atrial Fibrillation:converging genetic and clinical information [PDF]

, 2021
Atrial fibrillation is a common cardiac arrhythmia and is characterized by an irregular heart rate. Approximately one-third of the individuals above the age of 55 years will develop atrial fibrillation in their lifetime.

Recruited macrophages elicit atrial fibrillation

Science, 2023
Atrial fibrillation disrupts contraction of the atria, leading to stroke and heart failure. We deciphered how immune and stromal cells contribute to atrial fibrillation.

Ibandronate promotes autophagy by inhibiting Rac1–mTOR signaling pathway in vitro and in vivo

Cell Death Discovery, 2022
We previously reported that ibandronate (IBAN) could improve endothelial function in spontaneously hypertensive rats. However, the mechanism by which IBAN improves endothelial function is unclear.

Effectiveness of catheter ablation of atrial fibrillation according to heart failure etiology

Journal of Arrhythmia, 2020
Background Catheter ablation is an important rhythm control therapy in patients with atrial fibrillation (AF) with concomitant heart failure (HF). The objective of this study was to assess the comparative efficacy of AF ablation patients with ischemic vs

Atrial fibrillation and survival in colorectal cancer [PDF]

, 2004
BACKGROUND: Survival in colorectal cancer may correlate with the degree of systemic inflammatory response to the tumour. Atrial fibrillation may be regarded as an inflammatory complication.

Association of Sleep Duration With Atrial Fibrillation and Heart Failure: A Mendelian Randomization Analysis

Frontiers in Genetics, 2021
Both short (<7 h per night) and long (≥9 h per night) sleep durations are related to atrial fibrillation (AF) and heart failure (HF), but their causality has not been confirmed. We applied Mendelian randomization (MR) approaches to estimate the causal

Non-invasive estimation of left atrial dominant frequency in atrial fibrillation from different electrode sites: Insight from body surface potential mapping [PDF]

, 2014
© 2014, CardioFront LLC. All rights reserved. The dominant driving sources of atrial fibrillation are often found in the left atrium, but the expression of left atrial activation on the body surface is poorly understood.

Physical Activity and Risks of Cardiovascular Diseases: A Mendelian Randomization Study

Frontiers in Cardiovascular Medicine, 2021
Background: Although some observational studies have shown that physical activity may have a positive relationship with cardiovascular diseases, the causal effect remains uncertain.
