1/ #Frontline 
clinicians across the world are observing a #hypercoagulable state in patients with #COVID19. Could the severe and varied effects of the disease on multiple organ systems possibly be due to thrombus/micro-thrombus and associated sequela? @ASH_hematology @EricTopol https://twitter.com/NEJM/status/1248011487500795910

2/ Could a mechanism of #microvascular injury during the infection be through inappropriate effects of excess free angiotensin-II protein floating around because the ACE-2 that would normally be soaking it up is occupied by #SARSCOV2 particles? @EricTopol @ASH_hematology
3/ We know that ACE2 activation promotes antithrombotic activity and ACE2 deactivation would promote thrombus. #medtwitter #NurseTwitter #COVIDー19 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2811560/
4/ I was also thinking about the patient populations effected:
Men —> more ACE2
Post menopausal women —> more ACE2
Pregnant women —> higher risk for clot —> ACE2 expression increases in normal pregnancy 2nd trimester
Diabetes, HTN, Smoking —> preexisting vascular damage
Men —> more ACE2
Post menopausal women —> more ACE2
Pregnant women —> higher risk for clot —> ACE2 expression increases in normal pregnancy 2nd trimester
Diabetes, HTN, Smoking —> preexisting vascular damage
5/ So are the people that are more susceptible to #SARSCOV2 those with more ACE2 receptors at baseline? @ASH_hematology @EricTopol #medtwitter #nursetwitter
6/ The most striking reports have been interviews with clinicians on the front lines:
Neurology Today (Italy interview):
"There is a dramatic increase in the number of vascular events, ischemic strokes, and thrombosis..." https://journals.lww.com/neurotodayonline/blog/breakingnews/pages/post.aspx?PostID=920

7/ Another interview with an Italian anesthesiologist:
“We are performing daily echo on our patients in the ICU. We are seeing a number of patients with echo signs of pulmonary embolism (dilated right ventricle, tricuspid regurgitation). These patients are typically in the ICU...

8/…These patients are not necessarily ones who have been immobile in the ICU. We think this is because #COVIDー19 causes a massive hypercoagulable state, many patients have D-dimer levels extremely high on presentation..." https://www.mdcalc.com/covid-19/brescia-covid-respiratory-severity-scale-bcrss-interview

12/ @ASH_hematology recommends: "All hospitalized patients with #COVIDー19 should receive pharmacologic thromboprophylaxis with LMWH or fondaparinux (suggested over unfractionated heparin to reduce contact) unless patient has increased bleeding risk."

13/ @farid__jalali proposed a theory that has been widely circulated on @Facebook.

14/ Another theory by @VectorSting
"Physiology of COVID19 pneumonitis has the gist of shunt way out of proportion to lung injury. This suggests specific dysregulation of the pulmonary vascular compartment. Here is a hypothesis to explain why this might be the case..."

15/ Lastly, I am a Women’s Health NP. I fully acknowledge that I am not an infectious disease specialist, epidemiologist, immunologist, cardiologist, geneticist, or physician.
I just keep asking questions.
