With this statement from an autopsy you would never see the damage from the micro-strokes on any imaging.
Autopsies show this:
Translation: The lungs of the patients who died secondary to Covid-19 had wide-spread clotting, nine times more blood clots and blockages in the thousands of small capillaries and blood vessels in their lungs, compared with the lungs of patients who died from influenza.
I would demand my doctor treat me as if I had a stroke; warfarin, tPA, Lovenox if I came in with COVID-19. But I'm not medically trained so don't listen to me.
Confirmed ischemic stroke rates low in COVID-19

The study also found that most strokes in these patients were cryptogenic and were linked to increased mortality.
COVID-19 in New York
Researchers analyzed data from patients who were hospitalized for COVID-19 in the New York metropolitan area between March 15 and April 19. Two control groups were formed in this study; a contemporary control group included patients with stroke and without COVID-19, and a historical control group included patients who were discharged with a diagnosis of ischemic stroke between March 15 and April 15.All patients underwent a standard diagnostic evaluation per institutional protocol. Other information was abstracted from medical records including clinical and demographic variables, imaging variables, laboratory variables, discharge outcomes and in-hospital treatments. COVID-19 screening was performed at first provider contact.
Of the 3,556 patients who were hospitalized for COVID-19, 0.9% (n = 32; median age, 63 years; 72% men) had an ischemic stroke that was radiologically proven. The median time from the onset of COVID-19 symptoms to stroke identification was 10 days. Patients with COVID-19 and stroke were more likely to have cryptogenic stroke (65.6%) compared with the contemporary control (30.4%; P = .003) and historical control groups (25%; P < .001).
Compared with the contemporary control group, those with stroke and COVID-19 had higher peak D-dimer levels (> 10,000 ng/mL vs. 525 ng/mL; P = .011) and higher admission NIH Stroke Scale scores (19 vs. 8; P = .007). Patients with COVID-19 and stroke were more likely to be men (71.9% vs. 45%; P = .012) and had positive troponin levels (45.2% vs. 8.1%; P < .001), higher erythrocyte sedimentation rate levels (79 vs. 41; P = .001) and higher NIH Stroke Scale scores (19 vs. 3; P = .001) compared with the historical control group.
The mortality rate was higher in patients with COVID-19 and stroke compared with contemporary (63.6% vs. 9.3%; P < .001) and historical control groups (63.6% vs. 6.3%; P < .001).

“Studies are needed to determine the utility of therapeutic anticoagulation for stroke and other thrombotic event prevention in patients with COVID-19,” Yaghi said in an interview.For more information:
