Screening for Atrial Fibrillation in Older Adults
A two-week ambulatory electrocardiogram monitor in a large group of individuals 70 years of age or older with no history of atrial fibrillation (AF) showed a very low incidence of AF (4.4%), almost all of which was paroxysmal. In less than 2% of the subjects did it represent ≥ 2% of the monitoring time. However, some patients had hours of AF, raising a concern for thromboembolic risk.

A New Drug for Heart Failure with Preserved Ejection Fraction?
The addition of the nonsteroidal mineralocorticoid receptor antagonist finerenone to standard therapy reduced the incidence of recurrent heart failure and death compared to placebo in patients with heart failure and mildly reduced or preserved left ventricular ejection fraction and was generally well tolerated.

Risk of Atherosclerotic Coronary Artery Disease in Autoimmune Disorders
A large Danish registry study of patients with autoimmune disease referred for coronary computed tomography angiography compared to those without autoimmune disease has shown that autoimmune disease increases the incidence of atherosclerotic events and that the event rate is influenced by traditional atherosclerotic disease risk factors. These results support aggressive risk factor management in patients with autoimmune disease.

The Cath was “Clean!”
The featured electrocardiogram was obtained following successful resuscitation from cardiac arrest. Although echo done soon after showed akinesis of the anterior wall, no significant coronary narrowing was seen on cardiac catheterization. Can you explain? What is this phenomenon called?

CVD Risk from Ketogenic Diets
A recent analysis of the UK Biobank data found that subjects on a low-carbohydrate, high-fat diet had higher levels of low-density lipoprotein cholesterol and apolipoprotein B, and an increase in incident major adverse cardiovascular events over a 12-year follow-up than subjects on a standard diet.

A Run of Aberrant AFib?
The patient whose electrocardiogram (ECG) appears in the figure is a previously healthy man who presented to the emergency department because of acute dyspnea. What is the cause of the run of wide beats?

Complications of Implantable Cardioverter Defibrillators in the Emergency Department Setting
It is critical for providers in emergency department settings to be aware of the risks associated with implantable cardioverter defibrillator (ICD) placement and management of ICD malfunctions and complications.

Influenza Vaccination May Temporarily Aid Cardiovascular Event Prevention
Researchers studied English patients with an acute cardiovascular event who received an influenza vaccine in the same 12-month period and compared that to the 120-day period after vaccination and the rest of the year. They observed those vaccinated were less likely to experience an acute cardiovascular event for 120 days after vaccine vs. the rest of the year.

Patients Managing Severe Hypertension Should Avoid Drinking Too Much Coffee
Among patients with severe hypertension, drinking two or more cups of coffee a day was associated with twice the risk of death from cardiovascular disease, while green tea did not increase risk.
