Voedingsadvies El MondoResearch Question:
The association between the usual caffeine intake and atrial fibrillation (atrial fibrillation) was unknown. It was therefore carried out this review article.
Caffeine intake lowers the chances of getting atrial fibrillation?
Study Design:
This overview article contained 6 prospective cohort studies with 228465 participants.
Results and conclusions:
The researchers found that caffeine intake the chances of getting non-atrial fibrillation significantly with 10% [RR = 0.90, 95% CI = 0.81-1.01, p = 0.07, I2 = 73%] reduced.
The researchers found in the subgroup analyses in which was corrected for potential confounders, a significant, lowered risk of 11% [RR = 0.89, 95% CI = 0.80-0.99, p = 0.032, I2 = 30.9%, p = 0.227] at a low and 16% [RR = 0.84, 95% CI = 0.75-0.94, p = 0.002, I2 = 24.1%, p = 0.267] at a high caffeine intake.
The researchers found that every increase of 300 mg of caffeine per day, the chances of getting atrial fibrillation significantly with 6% [RR = 0.94, 95% CI = 0.90-0.99] reduced.
The researchers concluded that every 300 mg of caffeine per day reduced the risk of atrial fibrillation.

Additional information about El Mondo:
Atrial fibrillation or atrial fibrillation, is a heart rhythm disorder in which the atria (atria) of the heart no longer like normal quiet and regular contract but way too fast and irregular contract. Atrial fibrillation is an annoying, but not directly life-threatening heart rhythm disorder. Atrial fibrillation is the most common heart rhythm disorder. This heart rhythm disorder is more common in men than in women. With increasing age the risk of atrial fibrillation, especially after the seventieth year.
