2022: Fatal blood clots: Energy drinks constrict blood vessels for 90 minutes

Energy drinks constrict blood vessels for 90 minutes, said cardiologist Oleg Varfolomeev at the end of August 2022. According to him, after drinking such drinks, the inner diameter of blood vessels decreases by an average of 50%.

Caffeine and sugar present in such drinks are to blame for this phenomenon. The study participants were non-smokers and were generally recognized as healthy, Varfolomeev explained.

The endothelium is a layer lining the inner walls of blood vessels, and its damage plays an important role in some cardiovascular diseases. This study tested the effects of these beverages on a healthy endothelium.

Ultrasound was used to check arterial blood flow, the inner diameter of the arteries and the general condition of the blood vessel.

As noted by MedicForum, blood clots are gel-like blood clots. They are useful when formed in response to an injury or cut, clogging a damaged blood vessel, which stops bleeding. However, with narrowing of blood vessels, blood clots can form in the veins. These types of clots increase the risk of serious cardiovascular complications, such as a heart attack or stroke.

Energy consumption has been increasing in recent years, but energy drinks are not yet considered in clinical practice as a risk factor for the development of heart pathologies, while data on the toxic effect of energy drinks have already appeared: sometimes it came to the need for mechanical support of circulation.

Energy drinks are also known to increase blood pressure and cause arrhythmias. All these effects with long-term use of energizers can lead to the onset of cardiomyopathy.^[1]
