[메디컬투데이=남연희 기자] Studies have shown that drinking coffee reduces the risk of arrhythmia and cardiovascular disease by up to 24%.
Dr. Peter M. Kistler’s team at the Baker Heart and Diabetes Institute in Australia studied 382,535 people who participated in the Biobank project in the UK on different types of coffee consumption and arrhythmias, as well as cardiovascular diseases The results of the disease relevance analysis were published.
As a result of the study, the risk of death due to arrhythmia and cardiovascular disease could be reduced by up to 24% if you enjoyed coffee regardless of the type, including instant coffee, ground coffee, and decaffeinated coffee.
The research team divided the study subjects into 6 groups according to their daily coffee intake: 0 cups, less than 1 cup, 1 cup, 2-3 cups, 4-5 cups, and more than 5 cups.
Drinking 1 to 5 cups of instant or ground coffee per day has been shown to reduce the risk of arrhythmia, cardiovascular disease, coronary artery disease, heart failure, and stroke. The greatest reduction in the risk of death from cardiovascular disease was found when drinking ground coffee (26%), followed by decaffeinated coffee (15%) and instant coffee (10%).
The cardiovascular disease prevention effect was greatest when 2 to 3 cups of ground coffee or instant coffee were consumed per day. It showed a neutral effect (meaning it did not significantly increase or decrease risk) on the incidence of cardiovascular disease in people who consumed the same amount of instant coffee each day as those who drank 2 to 3 cups of ground coffee a day. Caffeine can speed up the heart, but it does not cause abnormal heart rhythms, the researchers concluded.
In fact, drinking a lot of coffee did not increase the risk of heart failure, including atrial fibrillation or atrial flutter.
Coffee contains up to 100 other substances apart from the most well-known caffeine. Antioxidants in coffee have been shown to reduce oxidative stress and inflammation, improve insulin sensitivity, boost metabolism, prevent visceral fat absorption, and help block receptors known to be associated with abnormal heart rhythms.
The findings were published in a recent issue of the Journal of the American College of Cardiology.
