COVID-19 may be silently accelerating the aging of our arteries, with women facing the sharpest impact.
A major international study found that even mild Covid infections can stiffen blood vessels as if they had aged five extra years, raising long-term risks of heart attacks and strokes.
Covid Infection May Accelerate Vascular Aging
A Covid infection may cause blood vessels to age by about five years, with the effect most pronounced in women, according to new research published in the European Heart Journal.[1]
Normally, arteries and veins stiffen gradually as part of the natural aging process. This study, however, suggests that Covid speeds up that change. Stiffer blood vessels are a concern because they raise the risk of cardiovascular problems, including stroke and heart attack.
The work was led by Professor Rosa Maria Bruno of Université Paris Cité in France. She explained: “Since the pandemic, we have learned that many people who have had Covid are left with symptoms that can last for months or even years. However, we are still learning what’s happening in the body to create these symptoms.
“We know that Covid can directly affect blood vessels. We believe that this may result in what we call early vascular aging, meaning that your blood vessels are older than your chronological age and you are more susceptible to heart disease. If that is happening, we need to identify who is at risk at an early stage to prevent heart attacks and strokes.”
How the Study Was Conducted
The study followed 2,390 participants from 16 countries (Austria, Australia, Brazil, Canada, Cyprus, France, Greece, Italy, Mexico, Norway, Turkey, UK and US) recruited between September 2020 and February 2022. Participants were divided into groups: those who had never had Covid, those with a recent infection but no hospitalization, those hospitalized on a general ward, and those admitted to intensive care.
To measure vascular aging, researchers used a device that tracks how quickly a blood pressure wave travels between the carotid artery in the neck and the femoral arteries in the legs. This measurement, known as carotid-femoral pulse wave velocity (PWV), indicates vessel stiffness. Higher PWV means the arteries are stiffer and therefore considered older in biological terms. Each participant was tested at six months after infection and again at 12 months.
Researchers assessed each person’s vascular age with a device that measures how quickly a wave of blood pressure travels between the carotid artery (in the neck) and femoral arteries (in the legs), a measure called carotid-femoral pulse wave velocity (PWV). The higher this measurement, the stiffer the blood vessels and the higher the vascular age of a person. Measurements were taken six months after Covid infection and again after 12 months.
Demographic information was also collected, including sex, age, and other cardiovascular risk factors that could influence results.
Covid’s Lasting Impact on Arteries
After taking these factors into consideration, researchers found that all three groups of patients who had been infected with Covid, including those with mild Covid, had stiffer arteries, compared to those who had not been infected. The effect was greater in women than in men and in people who experienced the persistent symptoms of long Covid, such as shortness of breath and fatigue.
The average increase in PWV in women who had mild Covid was 0.55 meters per second, 0.60 in women hospitalized with Covid, and 1.09 for women treated in intensive care. Researchers say
an increase of around 0.5 meters per second is “clinically relevant” and equivalent to aging around five years, with a 3% increased risk of cardiovascular disease, in a 60-year-old woman.
People who had been vaccinated against Covid generally had arteries that were less stiff than people who were unvaccinated. Over the longer term, the vascular aging associated with Covid infection seemed to stabilize or improve slightly.
Why Covid Damages Blood Vessels
Professor Bruno said: “There are several possible explanations for the vascular effects of Covid. The Covid-19 virus acts on specific receptors in the body, called the angiotensin-converting enzyme 2 receptors, that are present on the lining of the blood vessels. The virus uses these receptors to enter and infect cells. This may result in vascular dysfunction and accelerated vascular aging. Our body’s inflammation and immune responses, which defend against infections, may be also involved.
“One of the reasons for the difference between women and men could be differences in the function of the immune system. Women mount a more rapid and robust immune response, which can protect them from infection. However, this same response can also increase damage to blood vessels after the initial infection.
Addressing Accelerated Vascular Aging
“Vascular aging is easy to measure and can be addressed with widely available treatments, such as lifestyle changes, blood pressure-lowering, and cholesterol-lowering drugs. For people with accelerated vascular aging, it is important to do whatever is 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 establish whether the accelerated vascular aging they have found leads to an increased risk of heart attacks and strokes in the future.
Expert Reactions and Editorial Insights
In an accompanying editorial,[2] Dr. Behnood Bikdeli from Harvard Medical School, Boston, USA and colleagues said: “Although the acute threat of the COVID-19 pandemic has waned, a new challenge emerged in its aftermath: post-acute COVID-19 syndrome. Defined by the World Health Organization as symptoms appearing three months post-infection and lasting at least two months, studies suggest that up to 40% of initial COVID-19 survivors develop this syndrome.
“This large, multicenter, prospective cohort study enrolled 2390 participants from 34 centers to investigate whether arterial stiffness, as measured by PWV, persisted in individuals with recent COVID-19 infection. […] sex-stratified analyses revealed striking differences: females across all COVID-19-positive groups had significantly elevated PWV, with the highest increase (+1.09 m/s) observed in those requiring ICU admission.
“The CARTESIAN study makes the case that COVID-19 has aged our arteries, especially for female adults. The question is whether we can find modifiable targets to prevent this in future surges of infection, and mitigate adverse outcomes in those afflicted with COVID-19-induced vascular aging.”

Just remember, folks, whatever the virus does to you, the vaccine is doing to you, too, but worse.
As yet the vaccine has failed to make me cough up fresh blood from my lungs for two days; Covid-19 did that.
