What?
Stop and think. Covid vaccine adverse event reports are from 2021. They are from a search for cardiac arrest or myocarditis or tachycardia which is exactly what the doctor’s letter is about.
The d-dimmer scholarly article link includes some fron 2020.
As I responded you -- the scholarly work from 2020 in your google search talks about D-dimer as a prognosticator or mortality in diagnosed CoVID specifically. Did you not look at the titles or the actual articles? The 2020 articles have nothing to do with what the OP is about, and as I said, points out that how it is being used in the hospital by myself and my colleagues is for prognosis, not diagnosis. Your lack of understanding off covid adverse events reports (no doubt from VAERS which states specifically that no scientific conclusions can be drawn from its self reported database), and then stating it in combination with myocarditis (which the literature shows is brief and self limited after vaccination in the < 1% of cases in which it occurs) and tachycardia (do you even know what that means -- a fast heart rate -- so anyone who runs a mile after a vaccine at any time is subject to being called a complication?) demonstrates your complete lack of depth of knowledge of the topic at hand. Ridiculous.
