A frequent concern for doctors and patients is whether the daily consumption of 2-4 cups of coffee can lead to arrhythmias in susceptible individuals. Irregular heart rhythms, such as tachycardia or premature ventricular beats, are common and their incidence increases with age under normal circumstances.
A frequent concern for doctors and patients is whether the daily consumption of 2-4 cups of coffee can lead to arrhythmias in susceptible individuals. Irregular heart rhythms, such as tachycardia or premature ventricular beats, are common and their incidence increases with age under normal The University of Minnesota and the University of Minnesota have developed a new approach to heart rhythms.
A team from the University of Minnesota and the University of Minneapolis were the first organisations to investigate the issue of coffee and premature ventricular beats. They divided 7,311 men aged 35-57 years into seven groups based on no coffee consumption to more than 10 cups of coffee per day. The prevalence of ventricular premature contractions was 3.l% in the no coffee group and 3.2% in the 7-8 cups per day group, and only in those who drank more than 9 cups per day was the prevalence of ventricular premature contractions higher than 5%, so there was no causal relationship between moderate or high coffee consumption (up to 9 cups) and ventricular premature contractions.
However, many studies of the negative effects of caffeine on the cardiovascular system fail to mention any difference between habitual coffee drinkers and non-coffee drinkers. In fact, drinking 3 cups of coffee in an unexposed person can lead to significant changes in haemodynamics and body fluids. A study was conducted in which fasting people who drank coffee showed no change in heart rate or even a slight decrease in heart rate in the first hour. For the next 2 hours, the heart rate increased above baseline and the systolic blood pressure increased slightly, consistent with the highest levels of caffeine in the blood. However, a high degree of caution should be taken in patients with hypertension who drink more than 6 cups of coffee per day, especially those with high renin levels.
In addition to its antioxidant effects, coffee has other effects, such as the antidepressant effect of chlorogenic acid derivatives (lactones). Regular and moderate consumption of properly roasted coffee may be an important means of preventing many diseases, including diabetes and coronary artery disease.
Since coffee has been proven not only to have nothing to do with the misconception that it is bad for health, but also to have a positive effect on many chronic diseases, why don’t we put aside our prejudices and have some coffee in moderation, which is still very beneficial to our bodies! However, in view of modern life, we all consume too much sugar and fat in our diet, so I still suggest that those who start to try coffee, learn to try pure black coffee, not only to eliminate fat and fat, but also to reduce the burden of various additives on the body, so that the health benefits of coffee to the maximum.
