February 23, 2023 – In the most important and most comprehensive evaluation up to now, researchers found that the chance of heart attack or stroke after COVID is reduced by 41% in fully vaccinated people.
Even partial vaccination provided some protection and reduced the chance of a serious cardiac event by about 24%.
“To our surprise, even partial vaccination was associated with a lower risk of adverse cardiovascular events,” said researcher Joy Jiang in a opinion“Given the magnitude of SARS-CoV-2 infections worldwide, we hope our findings can help improve vaccination rates, particularly among people with comorbidities.”
Anyone who had received at the least two doses of the mRNA vaccine, akin to those from Moderna or Pfizer, or one dose of the Johnson & Johnson vaccine was considered fully vaccinated.
The study was published this week in Journal of the American College of CardiologyThe researchers examined data from greater than 1.9 million people aged 18 to 90 who were infected with COVID between March 1, 2020, and February 1, 2022. They were followed for 180 days after diagnosis. The average age was 45 years, and 56% of patients were women.
In addition to the dimensions and variety of the study, which give its findings significance, the evaluation was one among the primary to incorporate people vaccinated with the Johnson & Johnson vaccine alongside those that received the Moderna and Pfizer mRNA vaccines. The study was also the primary to look at the protection provided by partial vaccination, the authors said.
They identified that previous studies have shown that COVID infection increases the chance of significant heart problems and can also be related to long-term heart problems.
As the newest study shows, individuals with heart problems, type 2 diabetes, high cholesterol, obesity or liver disease are at increased risk of a serious cardiac event.
The authors explained that the study had limitations, amongst other things, since it couldn’t distinguish between repeat infections and couldn’t isolate the COVID-19 strain that caused the infection.
Nationally, COVID-19 cases proceed to say no, although about half of U.S. states are reporting some increase, in line with the New York Times Data tracker and that American Medical Association.
