Decrease in heart attacks and strokes after anti-Covid vaccination
Data on nearly 46 million adults reveal vaccinated people have a lower risk of developing arterial thrombosis
A new scientific discovery is revolutionizing our understanding of the benefits of anti-Covid vaccines. A large-scale study, conducted in the United Kingdom and published in the prestigious journal Nature Communications, revealed a surprising link between vaccination and a significant reduction in the risk of heart attack and stroke.
The study
The researchers analysed health data of almost 46 million adults in the UK, and finding that vaccinated people had a significantly lower risk of developing arterial thrombosis, a condition that can lead to heart attacks and strokes. This protective effect was observed after both the first and second doses of the vaccine.
Key results
The results of the study were unequivocal. Idati showed a:
- Risk reduction: Constant reduction of cardiovascular risk among vaccinated people, regardless of the type of vaccine received (AstraZeneca or Pfizer-BioNTech)
- Broader protection: In addition to arterial thrombosis, the study showed a lower incidence of other cardiovascular diseases, such as deep venous thrombosis and pulmonary embolism
Why does it happen?
The question that arises is: how do vaccines protect the heart? The most likely answer is related to the capacity of anti-Covid vaccines. We know that COVID-19 can cause widespread inflammation in the body, including the cardiovascular system, increasing the risk of blood clots and heart damage. Therefore, by reducing the severity of infection, vaccines indirectly also protect the cardiovascular system.
Vaccine: benefits greater than those of the ricin
This research represents an important breakthrough in understanding the benefits of anti-Covid vaccines. Benefits that “far outweigh the risks, which are extremely rare.” The Director of the BHF Data Science Centre, William Whiteley, said. “Our results provide convincing evidence that vaccination against Covid-19, in addition to protecting from disease, also offers significant benefits for cardiovascular health.” says Samantha Ip, a researcher at the University of Cambridge.
Implications for public health
This discovery has important implications for public health. First, it confirms the effectiveness of anti-Covid vaccines in protecting not only against acute disease but also its long-term complications. Secondly, it stresses the importance of continuing to promote vaccination at a global level, including among those who do not have risk factors for cardiovascular disease.
