NBC NEWS – A new study, published Monday in the Journal of the American College of Cardiology, suggests that vaccination may protect against major cardiovascular events — like heart attacks and strokes — associated with Covid.
The study analyzed data from nearly 2 million people in the National Covid Cohort Collaborative database.
About 218,000 had received at least one dose of either the Pfizer-BioNTech or Moderna mRNA vaccine, or Johnson & Johnson’s single dose vaccine.
Even partial vaccination was associated with lower risk of cardiovascular events for at least six months, the researchers found.
More research is needed to confirm whether Covid vaccination reduces the risk of these cardiovascular events, but the new study begins to broaden the understanding of the unknown long-term effects vaccines may have on the heart.
“There have been a lot of various messages about the efficacy of vaccines,” said study co-author Joy Jiang, an M.D./Ph.D. candidate at the Icahn School of Medicine at Mount Sinai in New York City. “
This pushes the narrative toward encouraging people to get vaccinated because of this associated benefit.”
ALSO: Here’s how Covid damages the heart
Covid can cause damage to the heart on a cellular level that can lead to lasting problems, including irregular heartbeats and heart failure, preliminary research suggests.
Covid’s effects on the heart have been well documented, but a new study zooms in on the microscopic changes thought to be caused by the virus.
Researchers from Columbia University in New York City examined autopsied heart tissue from people who had Covid, and found that the infection damaged the way cells in the heart regulate levels of calcium, a mineral that plays an important role in how the organ contracts and pumps blood throughout the body. In another part of the study, the same damage was seen in mice with Covid …
