The American Heart Association Posted a Expression of Concern in regards to the following Post that's been going around:

Abstract 10712: Mrna COVID Vaccines Dramatically Increase Endothelial Inflammatory Markers and ACS Risk as Measured by the PULS Cardiac Test: a Warning

We conclude that the mRNA vacs dramatically increase inflammation on the endothelium and T cell infiltration of cardiac muscle and may account for the observations of increased thrombosis, cardiomyopathy, and other vascular events following vaccination.

The AHA's Expression of Concern Post

This article expresses concern regarding abstract “Abstract 10712: Mrna COVID Vaccines Dramatically Increase Endothelial Inflammatory Markers and ACS Risk as Measured by the PULS Cardiac Test: a Warning” which originally published November 8, 2021; https://www.ahajournals.org/doi/10.1161/circ.144.suppl_1.10712.

Soon after publication of the above abstract in Circulation, it was brought to the American Heart Association Committee on Scientific Sessions Program’s attention that there are potential errors in the abstract. Specifically, there are several typographical errors, there is no data in the abstract regarding myocardial T-cell infiltration, there are no statistical analyses for significance provided, and the author is not clear that only anecdotal data was used.

We are publishing this Expression of Concern until a suitable correction is published to indicate that the abstract in its current version may not be reliable.

You can also look up Steven R Gundry other posts on the AHA website and decide if this is a reliable source.

I wanted to send the OG post to a relative so I wanted to sauce it, I might sure i can pass on the findings with confidence at this point.
