Researchers evaluated nearly 2,400 individuals from 16 countries – including the United States, France, and Brazil – between September 2020 and February 2022. Participants were grouped based on their Covid-19 exposure: those who had never contracted the virus, those with mild infections, those hospitalized on general wards, and those requiring intensive care. The study focused on carotid-femoral pulse wave velocity (PWV), a measure of artery stiffness. A higher PWV indicates older, less flexible blood vessels, and an increased risk of cardiovascular issues like stroke and heart attack.
The investigation, spearheaded by Professor Rosa Maria Bruno of Université Paris Cité in France, aimed to understand the long-term physiological effects of Covid-19. Professor Bruno explained the urgency of the study,stating,”We are still learning what’s happening in the body to create these long-term symptoms.”
Key Findings: Women More Vulnerable
The research team discovered that all groups who had experienced a Covid-19 infection exhibited increased artery stiffness compared to those who remained uninfected. Notably, the effect was more pronounced in women. Specifically, women with mild Covid-19 showed an average increase in PWV of 0.55 meters per second, while those hospitalized experienced a 0.60 m/s increase, and those in intensive care saw a notable 1.09 m/s increase.
Researchers determined that a 0.5 meters per second rise in PWV is clinically significant, roughly equivalent to five years of vascular aging and carries a 3% increased risk of cardiovascular disease for a 60-year-old woman. Vaccination against Covid-19 appeared to offer some protection, with vaccinated individuals showing less arterial stiffness compared to their unvaccinated counterparts.
| Covid-19 Exposure | Average PWV Increase (Women) | Equivalent Vascular Aging (Years) |
|---|---|---|
| Never Infected | Baseline | Chronological Age |
| Mild Covid-19 | 0.55 m/s | Approximately 5 years |
| Hospitalized (General Ward) | 0.60 m/s | Approximately 5 years |
| Hospitalized (ICU) | 1.09 m/s | Approximately 10 years |
Did You Know? The angiotensin-converting enzyme 2 (ACE2) receptors, which the Covid-19 virus targets, are found on blood vessel linings and play a crucial role in regulating blood pressure.
The Science Behind Vascular Aging & covid-19
Professor Bruno posited that the virus’s interaction with ACE2 receptors, combined with the body’s inflammatory response to infection, may be driving this accelerated aging process. Differences in immune responses between men and women may also contribute to the observed disparities, with women often mounting a more robust immune response that, while initially protective, could potentially cause more vascular damage.
This research echoes growing concerns about the long-term health consequences of Covid-19, often referred to as “long Covid.” Dr.Behnood Bikdeli of Harvard Medical School, in an accompanying editorial, underscored the emergence of post-acute Covid-19 syndrome, affecting up to 40% of initial survivors.
Pro Tip: Regular exercise, a heart-healthy diet, and managing stress levels are all proven strategies to maintain vascular health and mitigate the risk of cardiovascular disease.
Maintaining Vascular Health: A Long-Term perspective
Cardiovascular health is vital for overall well-being, and proactive measures can substantially reduce risk. As the American Heart Association notes,conditions like high blood pressure and high cholesterol contribute to arterial stiffness. Lifestyle modifications,including a diet rich in fruits,vegetables,and whole grains,coupled with regular physical activity,are crucial.According to the CDC, approximately 695,000 people in the United States died from heart disease in 2021, highlighting the pressing need for preventative care.
Frequently Asked Questions about Covid-19 & Vascular Health
- What is vascular aging? Vascular aging refers to the gradual stiffening of arteries, increasing the risk of cardiovascular diseases.
- How does Covid-19 affect blood vessels? covid-19 can directly impact blood vessels and trigger inflammation, potentially accelerating the aging process.
- Are men and women affected equally? No, the study found that women experienced a more significant increase in vascular aging following Covid-19 infection.
- Can vaccination protect against vascular damage from Covid-19? Yes, vaccinated individuals generally showed less arterial stiffness compared to unvaccinated individuals.
- What can I do to protect my vascular health? Lifestyle changes like exercise, a healthy diet, and managing stress, along with medical interventions when necessary, can definitely help maintain vascular health.
- Is the vascular aging caused by Covid-19 reversible? The study indicates it may stabilize or slightly improve over time, however, long-term effects are still being investigated.
- What is PWV? PWV stands for Carotid-Femoral Pulse Wave Velocity. It’s a measurement of how quickly blood pressure waves travel through arteries, used to assess artery stiffness.

What specific mechanisms contribute to endothelial dysfunction following a mild COVID-19 infection?
Long-term Vascular Aging Linked to Even Mild COVID-19 Infections
Understanding the Connection: COVID-19 and Vascular Health
Recent research increasingly points to a concerning link between even mild COVID-19 infections and accelerated vascular aging. This isn’t just about severe cases requiring hospitalization; individuals experiencing mild symptoms – or even asymptomatic infections – may be at risk of long-term cardiovascular consequences. Vascular aging, the stiffening and dysfunction of blood vessels, is a key driver of age-related diseases like heart disease, stroke, and dementia. COVID-19 appears to be exacerbating this process, possibly years after the initial infection. This is a critical area of study in post-COVID conditions and long COVID.
How COVID-19 Impacts Blood Vessels
The SARS-CoV-2 virus doesn’t just target the respiratory system. It can directly and indirectly affect the vascular endothelium – the inner lining of blood vessels. Here’s how:
endothelial Dysfunction: The virus can invade endothelial cells, causing inflammation and impairing their ability to regulate blood flow, blood clotting, and vascular permeability. This is a core component of cardiovascular complications post-COVID.
Inflammation & Oxidative Stress: COVID-19 triggers a systemic inflammatory response. Chronic inflammation and increased oxidative stress damage blood vessels over time, accelerating the aging process. Chronic inflammation is a key factor.
Microclots: Evidence suggests COVID-19 can lead to the formation of microclots in small blood vessels, restricting blood flow and contributing to tissue damage. These blood clots can have lasting effects.
Autoantibody Production: Some individuals develop autoantibodies after COVID-19 that attack their own endothelial cells, further damaging vascular function. This is an emerging area of research in immune dysregulation following infection.
Identifying Accelerated Vascular Aging: Key Indicators
Detecting accelerated vascular aging requires a proactive approach. Several indicators can signal potential problems:
Increased Blood Pressure: Even a slight,sustained increase in blood pressure can indicate vascular stiffness. Regular monitoring is crucial.
Arterial Stiffness: Measured through pulse wave velocity (PWV), this assesses how quickly blood travels through arteries. Higher PWV indicates stiffer arteries.
Endothelial Function Tests: These tests measure the ability of blood vessels to dilate and constrict properly.
Biomarkers: Elevated levels of certain biomarkers, such as inflammatory markers (CRP, IL-6) and markers of endothelial dysfunction, can suggest vascular damage.
Changes in cholesterol Levels: While not a direct indicator, significant shifts in cholesterol profiles can be associated with vascular health.
The Role of Severity: Mild vs. Severe COVID-19
while severe COVID-19 is undoubtedly linked to significant cardiovascular risks, the emerging data is particularly concerning regarding mild cases.
Mild Cases, Lasting Impact: Studies are showing that even individuals with mild, self-limiting COVID-19 infections can experience measurable increases in vascular age.
Dose-Response Relationship: There appears to be a dose-response relationship – the more severe the initial infection, the greater the potential for long-term vascular damage. However, even mild infections contribute.
Asymptomatic Infections: The impact of asymptomatic infections on vascular health is still being investigated, but preliminary findings suggest they may also contribute to accelerated aging. Silent infections pose a hidden risk.
Protecting Your Vascular Health Post-COVID: Practical Strategies
Taking proactive steps to protect your vascular health is crucial, especially after a COVID-19 infection.
- Regular Cardiovascular Check-ups: Schedule regular check-ups with your doctor to monitor blood pressure, cholesterol levels, and overall cardiovascular health.
- Healthy Diet: Adopt a heart-healthy diet rich in fruits, vegetables, whole grains, and lean protein. Limit processed foods, saturated and trans fats, and excessive sodium. Focus on anti-inflammatory foods.
- Regular Exercise: Engage in at least 150 minutes of moderate-intensity aerobic exercise per week. Exercise improves blood flow and strengthens the cardiovascular system. Physical activity is key.
- Stress Management: Chronic stress can contribute to vascular inflammation. Practice stress-reducing techniques like yoga,meditation,or deep breathing exercises.
- Hydration: Drink plenty of water to maintain healthy blood volume and circulation.
- Quit Smoking: Smoking is a major risk factor for vascular disease. Quitting smoking is one of the best things you can do for your cardiovascular health.
- Consider Supplements (with doctor’s approval): Some supplements, like Omega-3 fatty acids and Vitamin D, may support vascular health, but always consult your doctor before starting any new supplement regimen.
Real-World Examples & Emerging Research
A study published in nature Cardiovascular Research in early 2023 followed a cohort of individuals post-COVID-19 and found a significant increase in PWV, indicating accelerated arterial stiffness, even in those who had experienced only mild symptoms. Another study, conducted by researchers at Mount Sinai, revealed persistent endothelial dysfunction in a significant percentage of patients months after their initial infection, irrespective of disease severity. these findings underscore the
