The clotting issues of the coronavirus continue to become more clear. A Dutch study reports that 50% of ICU COVID patients have blood clots in their lungs or brain, leading to infarctions and aneurysms.
There have been reports of patients being released from hospital with a clean bill of health, only to die of a heart attack.
The very first known patient in the US herself died of a 'burst' heart which imploded as blood pooled around it.

In light of this, those scary videos from China and Iran of people collapsing in the street make sense.
There is a lot more going on with this virus and how it affects blood than we at first realised, and this is likely a strong cause of mortality for this virus rather than ARDS of the lungs per se.
Anticoagulant drugs such as Warfarin, etc may be a lifesaver in treating COVID and should now be included as part of a standard treatment regimen. Antiplatelet drugs which reduce the likelihood of clotting (aspirin, etc) might also be helpful.
