\u201cSince the pandemic, we have learned that many people who have had (COVID-19) are left with symptoms that can last for months or even years. However, we are still learning what\u2019s happening in the body to create these symptoms,\u201d lead researcher Rosa Maria Bruno from Universit\u00e9 Paris Cit\u00e9, France<\/a>, said.
The study, published in the European Heart Journal, looked at around 2,400 people \u2014 about half were women \u2014 from across 16 countries, including Australia<\/a>, Brazil and those in Europe.
While blood vessels are known to become stiffer with age, a COVID-19 infection can accelerate the process and can heighten the risk of developing cardiovascular disease, including stroke and heart attack, the researchers said.
The participants\u2019 vascular (blood vessel) age was measured using a device that looks at how quickly a wave of blood pressure travels between the carotid artery (in the neck) and femoral arteries (in the legs) \u2014 called \u2018carotid-femoral pulse wave velocity\u2019.
A higher value indicates more stiffness and ageing of blood vessels. Measurements were taken six months after a COVID-19 infection and again after 12 months.
An increase in pulse wave velocity of around 0.5 metres per second is clinically relevant and roughly amounts to ageing by five years, with a three per cent increased risk of cardiovascular disease, in a 60-year-old woman, the researchers said.
The study found that, on average, pulse wave velocity among women who had a mild infection was increased by 0.55 metres per second, by 0.60 metres per second in those hospitalised and by over one metre per second for women treated in intensive care.
\u201c(Pulse wave velocity) differences were significant in women, but not in men. Among COVID-19 positive women, persistent symptoms were associated with higher (pulse wave velocity),\u201d the authors wrote.
\u201cA stable or improved (pulse wave velocity) after 12 months was found in COVID-positive groups, whereas a progression was observed in the COVID-negative group,\u201d they wrote.
Explaining how COVID-19 impacts blood vessels, Bruno said that the disease-causing virus \u201cacts on specific receptors in the body, called the angiotensin-converting enzyme 2 receptors, that are present on the lining of the blood vessels.\u201d \u201cThe virus uses these receptors to enter and infect cells. This may result in vascular dysfunction and accelerated vascular ageing. Our body\u2019s inflammation and immune responses, which defend against infections, may also be involved,\u201d the lead researcher said.
Further, compared to men, women are known to produce a more rapid and robust immune response which can protect from infection but can also inflict damage on blood vessels after initial infection, Bruno said.<\/p>\n
