Direct oral anticoagulants (DOACs) can cut the short-term risk of thromboembolic events in half for patients who have undergone cardioversion of atrial fibrillation (AFib), suggests a meta-analysis published in the Journal of the American College of Cardiology.

When cardiologists get involved in the treatment of patients with a history of cancer and newly diagnosed atrial fibrillation (AFib), those people see a subsequent 11 percent reduction in the risk of stroke, according to a new study in the Journal of the American College of Cardiology. But those visits occur less often for that subgroup of patients than in AFib patients without cancer.

Digoxin, a cardiac glycoside popularly sold under the brand name Lanoxin, poses a major threat to the heart health of atrial fibrillation (AF) and heart failure (HF) patients, according to a review published in the American Journal of Cardiology Oct. 4. Even without confounding conditions, the drug can raise an individual’s risk of all-cause mortality.

“The people most in need of it, those who might benefit from tests and distance monitoring, are the least likely to get (the Apple Watch),” Aaron E. Carroll, MD, wrote in the New York Times. “If we truly believed this was a medical test beneficial to the general population, insurance should pay for it."

The long-held belief that sudden cardiac arrests (SCAs) occur most commonly on weekday mornings has been debunked by a team in Portland, Oregon, whose recent study of more than 1,500 SCA victims failed to identify any peak windows during which heart patients were prone to sudden cardiac death.

In patients with atrial fibrillation who have experienced MI or undergone percutaneous coronary intervention (PCI), treatment with a combination of direct oral anticoagulants (DOACs) and dual antiplatelet therapy (DAPT) could significantly decrease the risk of bleeding and other major thromboembolic events, according to research published ahead of print in the Journal of the American College of Cardiology.

Increases in tricuspid regurgitation (TR) severity occurred in 11.5 percent of patients following transvenous lead extraction, according to a single-center study, which also identified lead age as an important predictor of acute TR increases and tricuspid valve injury.

A patient’s odds of surviving out-of-hospital cardiac arrest (OHCA) fluctuate an average of 56 percent from one emergency medical services (EMS) agency to another, researchers reported Sept. 26 in JAMA Cardiology.
