Many coffee does not harm heart - scientists

The debate about what effect of coffee on health cores, do not cease for many decades. In the new study, experts have attempted to resolve this issue definitively.

One of the most common diseases of the heart is atrial fibrillation. If it is one of the phases of the cardiac cycle (namely, the atria) is lost. As a result, one can observe a chaotic twitching of the atria, or so-called flicker. The patient may experience thrombus formation and heart failure. Furthermore, one of the scenarios of the disease may become ischemic stroke: it is the result of contact with blood through the blood clots in the human brain.

Atrial fibrillation is often associated with the use of high doses of alcohol. But what about coffee? Susanna Larsson (Susanna Larsson) from Sweden and his colleagues conducted a large-scale study that affected 80 thousand. Citizens of the Nordic countries and the United States. Experts conducted polls for drinking coffee and other caffeinated beverages, as well as fixed heart and blood vessels. Approximately 9% of participants in the experiment suffered from atrial fibrillation. Total observation lasted more than 12 years.

It was found that even if a person tried coffee in very large quantities, it does not result in atrial arrhythmia. We do not face additional difficulties and those who already had the disease. To confirm the findings, the researchers expanded the group of volunteers, as well as analyzed the works of their colleagues. As a result, the number of study participants increased to 250 thousand.

The results of additional analysis remained unchanged: Caffeine slightly increases the chances of developing the disease in men and decreased in part those of women. The scientists say that coffee lovers are afraid of nothing. Anyway, atrial fibrillation is not associated with frequent consumption of the drink.

Among the admirers of coffee was a French Enlightenment philosopher Voltaire. It is known that on the day he drank about 50 cups of the drink and still lived to be 83 years. The composer Ludwig van Beethoven began his day with a cup of coffee, which is brewed from 60 grains.

Not so long ago, other researchers found that the drink a few cups of coffee a day a person has 15% less likely to die in a short time than one who does not drink at all. Similar conclusions are reached and green tea. However, it should be understood that in certain diseases of the heart strong coffee, and even in large quantities actually contraindicated.
