300 mg cafeïne per dag verlaagt atriumfibrillatie

Research 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.
