The so-called “weekend effect”—that idea that patients admitted to the hospital on Saturdays, Sundays and holidays face greater odds of readmission down the line—doesn’t apply to victims of cardiac arrest, according to data presented at the British Cardiovascular Society Conference in Manchester June 2.

Consuming 32 ounces or more of an energy drink within an hour could raise blood pressure and trigger life-threatening arrhythmias, according to research published ahead of print in the Journal of the American Heart Association.

People living in the Canadian province of Manitoba are facing up to 70-week waits for elective echocardiograms, CBC reported May 28—dozens of weeks longer than those living in neighboring Saskatchewan and Ontario provinces.

Women are less likely to be resuscitated by bystanders than men in cases of out-of-hospital cardiac arrest, and when resuscitation is attempted they see lower survival rates, according to research published in the European Heart Journal May 21.

An absorbable, antibiotic-eluting mesh envelope significantly reduced the incidence of major cardiac implantable electronic device (CIED) infections in a recent study of nearly 7,000 patients, researchers reported in the New England Journal of Medicine May 16.

A six-week online training course centered around living with an implantable cardioverter-defibrillator (ICD) helped alleviate anxiety in heart failure patients who were apprehensive about their devices.

Researchers at Florida Atlantic University’s College of Engineering and Computer Science have developed an algorithm that can identify precise internal targets for ablation in atrial fibrillation patients—the first, they say, that can do so without the help of specialized catheters or 3D electroanatomic mapping.

A high intake of grapefruit juice—and other dietary flavonoids found in fruits, vegetables, tea and wine—could correspond to QT interval prolongation in healthy individuals and those with heart disease, leaving them vulnerable to serious arrhythmias like torsades-de-pointes.
