The effect of coffee on the functional state of the cardiovascular system has been shown by numerous experiments and medical observations..

Finnish scientists in this article analyzed the results of many studies on the relationship between coffee consumption and the development of cardiovascular disease (CVD).

Coffee and the risk of coronary heart disease Long-term follow-ups in large populations have been mixed, with many studies finding an association between frequent coffee consumption and the development of coronary heart disease (CHD).

Regular coffee drinkers have approximately 10% higher cholesterol levels than non-drinkers.. According to available scientific data, a 1% increase in blood cholesterol increases the risk of developing coronary artery disease by 2%. It is becoming clear that regular coffee consumption can increase the risk of coronary heart disease by approximately 20%..

At the same time, it was noted that the increase in blood cholesterol is observed mainly in people who drink coffee prepared by boiling, while coffee prepared by passing water or steam through a filter, and some varieties of instant coffee do not lead to an increase in the level.

Boiled coffee is known to contain a fat-like substance that raises cholesterol.. This substance is sometimes found in additives that are introduced to improve the taste in instant coffee..

In this way. The effect of coffee on blood cholesterol levels depends on how it is prepared.. The authors even believe that the 10% reduction in cholesterol levels in Finns over the past two decades is half due to the fact that they switched from making coffee by boiling to making it by filtering..

Coffee and blood pressure.

Drinking coffee causes a short-term increase in blood pressure, and in hypertensive patients. Systolic pressure usually rises by 4-14 mmHg. st. (often called upper pressure), diastolic - by 5-6 mm Hg. st. , and this level persists for about 3-4 hours. However, people who drink coffee regularly. such an increase in pressure may not be observed due to addiction.

Studying the effect of coffee on blood pressure is made more difficult by the fact that regular coffee drinkers are more likely to smoke and drink more alcohol, two factors that independently affect blood pressure..

Coffee and smoking.

Drinking coffee and smoking at the same time causes more blood pressure than either alone.

Studies have shown that the caffeine in the body of a smoker breaks down faster, so smokers drink more coffee to maintain the level of caffeine in the blood at the usual level..

This must be remembered by those who quit smoking.. If they continue to drink the same amount of coffee, this can lead to a 2.

5-fold increase in caffeine blood levels..

Coffee and irregular heart rhythms.

Caffeine, as experimental studies show, can lead to irregular heart rhythms. True, the amount of coffee or tea that will cause a negative reaction of the body is quite significant - 7-9 cups a day..

Therefore, we do not recommend abusing coffee for those who already have heart rhythm disturbances..
