Energy drinks and atrial fibrillation

Atrial fibrillation in healthy adolescents after highly caffeinated beverage consumption: two case reports.

Energy drinks and highly caffeinated drinks comprise some of the fastest growing products of the beverage industry, often targeting teenagers and young adults. Cardiac arrhythmias in children related to high caffeine consumption have not been well described in the literature. This case series describes the possible association between the consumption of highly caffeinated drinks and the subsequent development of atrial fibrillation in the adolescent population.

We report the cases of two Caucasian adolescent boys of 14 and 16 years of age at the time of presentation, each without a significant cardiac history, who presented with palpitations or vague chest discomfort or both after a recent history of excessive caffeine consumption. Both were found to have atrial fibrillation on electrocardiogram; one patient required digoxin to restore a normal sinus rhythm, and the other self-converted after intravenous fluid administration.

With the increasing popularity of energy drinks in the pediatric and adolescent population, physicians should be aware of the arrhythmogenic potential associated with highly caffeinated beverage consumption. It is important for pediatricians to understand the lack of regulation in the caffeine content and other ingredients of these high-energy beverages and their complications so that parents and children can be educated about the risk of cardiac arrhythmias with excessive energy drink consumption.

JP says January 30, 2013

Claire Squires, 30, suffered a cardiac arrest and collapsed in Birdcage Walk near Buckingham Palace, a few hundred metres from the finish line.

An inquest into her death heard that she had purchased a popular powder supplement called Jack3d which contained DMAA (dimethylamine), a drug that has similar properties to amphetamines and is said to boost energy, concentration and metabolism.

Her boyfriend, Simon van Herrewege, told Southwark Coroner’s Court that she bought it online and mixed it with liquid in her water bottle as she was keen to beat her personal best race time.

“It is a bit like caffeine,” he said.

“She said that if ‘I hit a bit of wall I will take it’.”

BBC: Vegetarians ‘cut heart risk by 32%’

Ditching meat and fish in favour of a vegetarian diet can have a dramatic effect on the health of your heart, research suggests…Differences in cholesterol levels, blood pressure and body weight are thought to be behind the health boost.

    I would bet on the healthy user or compliance effect: those with healthier habits (exercise, moderate alcohol, etc.) or genetic predisposition (such as high IQ) are more likely to be both healthy and vegetarian.

Healthline just designed a virtual guide of how atrial fibrillation affects the body. You can see the infographic here:

This is valuable med-reviewed information that can help a person understand the effects of afib of their body. I thought this would be of interest to your audience, and I’m writing to see if you would include this as a resource on your page:

If you do not believe this would be a good fit for a resource on your site, even sharing this on your social communities would be a great alternative to help get the word out.

Thanks so much for taking the time to review. Please let me know your thoughts and if I can answer any questions for you.
