Syncope in Athletes: A Prelude to Sudden Cardiac Death?

Athletes are generally healthy but might have certain cardiac disorders which might, during athletic participation or training, result in cardiac symptoms including syncope. Vasovagal syncope is probably the most common cause of syncope in athletes, but syncope in the context of these cardiac disorders might be a warning of sudden death.

N-Acetylcysteine and Atherosclerosis: Promises and Challenges.

Atherosclerosis remains a leading cause of cardiovascular diseases. Although the mechanism for atherosclerosis is complex and has not been fully understood, inflammation and oxidative stress play a critical role in the development and progression of atherosclerosis. N-acetylcysteine (NAC) has been used as a mucolytic agent and an antidote for acetaminophen overdose with a well-established safety profile.

Heart rate and death and hospitalization for heart failure in patients with persistent or permanent atrial fibrillation: Insights from the ARISTOTLE trial.

Rate control is fundamental in the treatment of patients with atrial fibrillation (AF). The independent association of heart rate with outcomes and range of heart rate associated with best outcomes remains uncertain. We assessed the relationship between heart rate and clinical outcomes in patients with persistent or permanent AF enrolled in the randomized, double-blind ARISTOTLE trial.

Trends in Oral Anticoagulant Use Among 436 864 Patients With Atrial Fibrillation in Community Practice, 2011 to 2020.

Background Among patients with nonvalvular atrial fibrillation (AF) and an elevated stroke risk, guidelines recommend direct oral anticoagulants (DOACs) over warfarin for stroke prevention. Changes in DOAC use over the past decade have not been well described. Methods and Results We evaluated trends in use of DOACs and warfarin from 2011 to 2020 among adults with AF and a CHADS-VASc score ≥2 based on electronic health record data from 88 health systems in the United States contributing to Cerner Real World Data.
