You try so hard, but it all starts with insults of what you dont understand, then comes down to left and right for you. I'm not a liberal, not politically motivated in my thinking and actually more conservative politically. I'm talking about science and medicine that a segment of the population want to deny is evidence based.
COVID-19 doesnt "mirror vascular diseases" in some cases like you say. Like I mentioned earlier in this thread....COVID-19 's gateway into the bloodstream is ACE-2 receptors and from there can attack any area of the body that there is blood flow.
I was first made aware of this when I was told by physicians that Covid patients were experiencing endocarditis. The initial experience was respiratory ailments and fluid buildup in the lungs required draining, but then the endocarditis resulted in fluid buildup in the pericardium. From there the connection with ACE-2 was made. Different demographics have differing levels of ACE-2 receptors, but I'm sure you already know that info.
Hydroxychloroquiine was shown in multiple studies to not be effective in treating Covid-19 and even to the point where health authorities warned against its use and deemed it off label use. It was politicized as beneficial, but wasnt even used in the treatment plan of President Trump while at Walter Reed, when positive with COVID-19.
