Even moderate covid may leave the blood vessels over five years

The blood vessels become more solid with age, but the new study indicates that Covid can accelerate this process. The researchers say this is important because people with the most solid blood vessels face a greater risk of cardiovascular disease, including stroke and heart attack.

The study was led by Professor Rosa Maria Bruno of the University of Paris City, France. She said: “Since the epidemic, we have learned that many people who have coffee have been leaving symptoms that can last for several months or even years. However, we are still learning what is happening in the body to create these symptoms.

“We know that Covid can directly affect the blood vessels. We believe that this may lead to what we call early blood vessels, which means that your blood vessels are older than your time and that you are more likely to have heart disease. If this happens, we need to determine who is at an early stage to prevent heart attacks and strokes.”

The study included 2,390 people out of 16 different countries (Austria, Australia, Brazil, Canada, Cyprus, France, Greece, Italy, Mexico, Norway, Turkey, the United Kingdom and the United States) who were recruited between September 2020 to February 2022. They were classified according to whether they had a newly delegate, not chosen in the hospital, and she was hospitalized, where they were stored in Hospital. The intensive care unit.

The researchers evaluated the age of each person from the era of blood vessels with a device that measures the speed in which a wave of blood pressure is transmitted between the carotid artery (in the neck) and the thighs (in the legs), a scale called the speed of the pulse wave (PWV). The higher this measurement, the more stiff the blood vessels and the height of a person’s vascular age. The measurements were taken six months after the Covid injury and again after 12 months.

Researchers also recorded demographic information such as patient gender, age and other factors that can affect cardiovascular health.

After taking into account these factors, the researchers found that the three groups of patients who had Covid, including those who suffer from moderate Covid, had more solid arteries, compared to those who did not get. The influence in women was more than men and people who suffered from long long symptoms, such as shortness of breath and fatigue.

The average PWV increase in women who suffer from Kofid was 0.55 meters per second, 0.60 in women in the hospital with Covid, and 1.09 for women who are treated in intensive care. The researchers say

An increase of about 0.5 meters per second is “clinically related” and equivalent to aging about five years, with an increased risk of cardiovascular disease by 3 %, in a 60 -year -old woman.

People who were vaccinated against Kovid were generally arteries were less solid than unprecedented people. In the long run, the aging of the blood vessels associated with infection settled or improving a little.

Professor Bruno said: “There are many potential explanations for the vascular effects of Covid. The Covid-19 virus works on specific receptors in the body, called transformed angiotensin receptors, which are present on the lining of the blood vessels. Inflammation and immune responses, which defend against infection, may participate.

“One of the reasons for the difference between women and men can be the differences in the function of the immune system. Women prove a faster and strong immune response, which can protect it from infection. However, this same response can increase the damage to blood after the initial injury.

“It is easy to measure blood vessel aging and can be treated with widely available treatments, such as lifestyle changes, lowering blood pressure and lowering medications to lower cholesterol. For people with rapid blood vessels aging, it is important to do everything possible to reduce the risk of heart attacks and strokes.”

Professor Bruno and her colleagues will continue to follow the participants over the coming years to prove whether the accelerated vascular aging that is found increasing the risk of heart tools and strokes in the future.

“Although the sharp threat of Covid-19 epidemic has faded, a new challenge has emerged in the aftermath of the aftermath, the following is related to 40 % of the first syndrome. Covid-19 survivors develop this syndrome.

“This is the large and multi-centers study that recorded 2390 participants from 34 centers to investigate whether it is atherosclerosis, as measured by PWV, continued in individuals with modern Covid-19 infection. It was observed in those who require acceptance of the intensive care unit.

“The COVID-19 has been enacted in arterial age, especially for female adults. The question is whether we can find adjustable goals to prevent this in the future bleeding of infection, and reduce harmful results in those with blood vessels caused by Covid-19.”
