    How do you take your caffeine? Caffeine is a stimulant that has been linked to improving the functioning of your brain. It is not surprising that it is one of the most used drugs on the planet. The most common forms of caffeinated beverages include coffee, tea, and energy drinks. New research in the Journal of the American College of Cardiology suggests that caffeine is not harmful to the heart, as previously suggested, and that it could actually be beneficial. Caffeine works by adding more energy to the inside of your cells. Because it is known that caffeine makes the heart beat faster, many people believe that it can damage the heart's electrical system. In fact, more than 80 percent of physicians in the US UU They recommend avoiding caffeine consumption in patients with known abnormal heart rhythms. Many feel that the faster heart rate makes their heart more vulnerable to entry to life-threatening rhythms. On the other hand, caffeine has also been described as an antioxidant. Antioxidants neutralize the negative waste products from the day-to-day activities of your cells and are thought to preserve the long-term health of your cells and tissues. Some scientists believe that caffeine protects the longevity of the heart muscle. Heart doctors do not have much evidence that caffeine causes abnormal heart rhythms. The current recommendations against caffeine are conservative and are based mainly on assumptions about how the body works. A new article in the Journal of the American College of Cardiology compiles data from multiple studies to add scientific data to the debate on caffeine.Regarding the results: multiple studies associate regular coffee drinkers with lower amounts of new-onset atrial fibrillation, commonly referred to as "a. Fib." Atrial fibrillation is a very common irregular heart rhythm that increases the risk of stroke. Approximately 9 percent of Americans over 65 have this abnormal rhythm, according to the US Centers for Disease Control and Prevention. UU The treatment usually includes medications to control your heart rate and, potentially, anticoagulants.Researchers in this article discusses other types of abnormal rhythms, including supraventricular tachycardia (SVT) and ventricular fibrillation ("v. Fib"). There were no studies that found an association between caffeine and these rhythms, even in patients who already had hearts sick from heart attacks or heart failure.While this information can be exciting for our regular customers "low fat, medium sugar and very hot", it is very important to keep in mind that some patients with atrial fibrillation have a negative relationship with caffeine. In 25 percent of people who already have a diagnosis of atrial fibrillation, caffeine can actually trigger an episode of the abnormal rhythm. As always, it is important to consult your doctor before making any changes.So here is the good news.The authors do not believe that caffeine causes most of the abnormal heart rhythms. In fact, they suggest that regular coffee use actually protects patients from atrial fibrillation. However, according to data from some animal trials, they recommend a maximum of 300 mg of caffeine per day. This is the equivalent of about three cups of coffee.If your coffee or tea is your drug of choice, you're lucky. If it is an energy drink, not so much. While coffee and tea seem to be quite safe, research suggests that most energy drinks are a bit riskier. Unfortunately for some of our readers, multiple studies recommend against the consumption of energy drinks. The researchers suggest that these drinks can cause life-threatening rhythms and even blood clots. In addition to high amounts of caffeine, they often have other ingredients such as guarana, sugar, and ginseng. These additives appear to amplify the body's response to the stimulant, causing more damaging side effects, including abnormal heart rhythms.Laura Shopp, MD, a third-year resident of pediatrics affiliated with Indiana University, works at the ABC News Medical Unit.
