Understanding the Mechanism of Cardiotoxicity Induced by Nanomaterials: A Comprehensive Review

open access: yesSmall Science, EarlyView.
This review provides a bibliometric analysis for understanding the study of nanotoxicity on cardiovascular health. It begins by outlining the pathways through which nanomaterials enter the cardiovascular system, followed by a summary of the mechanisms underlying nanomaterial‐induced cardiotoxicity.

Deciphering Heartbeat Signatures: A Vision Transformer Approach to Explainable Atrial Fibrillation Detection from ECG Signals [PDF]

open access: yesarXiv
Remote patient monitoring based on wearable single-lead electrocardiogram (ECG) devices has significant potential for enabling the early detection of heart disease, especially in combination with artificial intelligence (AI) approaches for automated heart disease detection. There have been prior studies applying AI approaches based on deep learning for

Impact of Renal Impairment on Beta-Blocker Efficacy in Patients With Heart Failure. [PDF]

open access: yes, 2019
BACKGROUND: Moderate and moderately severe renal impairment are common in patients with heart failure and reduced ejection fraction, but whether beta-blockers are effective is unclear, leading to underuse of life-saving therapy.

Treatment of focal junctional tachycardia using ivabradine in a dog

open access: yesVeterinary Record Case Reports, EarlyView.
Abstract A 10‐year‐old labrador retriever was referred as an emergency due to ascites and lethargy. Physical examination revealed a regular tachycardia at 160 beats per minute with a Grade 3/6, left apical systolic heart murmur. The dog was diagnosed with severe myxomatous mitral valve disease with biventricular congestive heart failure (mild pulmonary

Studying ECG signals using nonlinear oscillators and Genetic Algorithm [PDF]

open access: yesarXiv
Cardiovascular diseases are the leading cause of death and disability in the world and thus their detection is extremely important as early as possible so that it can be prognosed and managed appropriately. Hence, electrophysiological models dealing with cardiac conduction are critically important in the field of interdisciplinary sciences. The primary

Atrial Fibrillation and Hyperthyroidism [PDF]

open access: yes, 2005
Atrial fibrillation occurs in 10 – 15% of patients with hyperthyroidism. Low serum thyrotropin concentration is an independent risk factor for atrial fibrillation. Thyroid hormone contributes to arrythmogenic activity by altering the electrophysiological

Impact of atrial fibrillation on the cardiovascular system through a lumped-parameter approach [PDF]

open access: yes, 2014
Atrial fibrillation (AF) is the most common arrhythmia affecting millions of people in the Western countries and, due to the widespread impact on the population and its medical relevance, is largely investigated in both clinical and bioengineering ...
