Recent studies have found compelling evidence of increased risks of heart attacks and strokes long after a Covid-19 infection. These findings suggest that the cardiovascular impact of the virus could persist for up to three years.
A comprehensive study involving the UK Biobank database, which covers roughly a quarter of a million individuals, has revealed startling insights into the long-term cardiac risks associated with Covid-19. Specifically, individuals who contracted the virus in 2020 faced a risk of heart attack or stroke that was twice as high as those who never tested positive. This risk persisted nearly three years post-infection.
Dr. Stanley Hazen, a leading researcher, emphasised that this sustained risk is uncommon compared to other infections. He indicated that the study’s results showed no attenuation of this risk over time.
Further investigations are ongoing to understand the exact mechanisms by which the virus affects long-term cardiovascular health, with theories suggesting sustained damage to the blood vessel walls.
Despite the slight protection offered by blood type O, all individuals with a Covid-19 history remain at elevated risk. Blood type is just one of numerous factors contributing to this complex relationship.
While the study did not examine the impacts of Covid vaccinations on long-term cardiac risks, it is speculated that vaccinations could offer protective benefits by reducing the severity of the infection.
It remains essential to explore whether repeated infections further exacerbate heart risks, an area that necessitates further research.
Medical professionals should incorporate a patient’s Covid history into their cardiovascular risk assessments as part of routine practice. This proactive approach allows for better management of potential long-term heart risks associated with previous Covid-19 infections.
The study underscores the long-term impact of Covid-19 on cardiovascular health, urging individuals and healthcare providers to remain vigilant. Ongoing research is critical to fully understand the underlying mechanisms and potential mitigation strategies.
