Scientists from the National Health Insurance Service in South Korea found that full vaccination against COVID-19 is linked to a lower risk for heart attack and stroke 31 to 120 days after COVID-19.
The research is published in the Journal of the American Medical Association and was conducted by Young-Eun Kim et al.
In the study, the team compared the incidence of heart attacks and strokes after COVID-19 (July 2020 to December 2021) between patients who were never vaccinated (62,727 individuals) and those who were fully vaccinated (168,310 individuals) with two doses of mRNA vaccines or a viral vector vaccine against severe COVID-19.
The researchers found hospitalizations for heart attack and stroke (31 to 120 days after COVID-19 diagnosis) had an incidence of 6.18 versus 5.49 per 1 million person-days for unvaccinated versus vaccinated people.
In the fully vaccinated group, the overall risk was much lower, including for both heart attack and stroke.
While a lower risk for outcome events in fully vaccinated patients was found in all subgroups, it was not significant for those with severe or critical infections.
These findings support vaccination, especially for those with risk factors for heart diseases.
If you care about COVID, please read studies about antibodies that block all the COVID-19 variants, and Kidney injury from COVID-19 may be twice as common as diagnosed.
For more information about COVID, please see recent studies about common asthma drugs that could help treat COVID-19, and results showing vaccines have up to 90% efficacy against severe COVID-19 for up to 6 months.
