As I understand (DOI I have not read the paper relying on others interpretation) the lancet paper is hypothetical not hard evidence. European society of cardiology has an excellent position paper on the use of ACE- inhibitors/A2RBs that is available on their website.
w.r.t the last FAQ point, I have tried to dissect the Lancet letter in question, and am wondering if my interpretation is correct;https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30116-8/fulltextBasically what I understand is that if you are taking ACE Inhibitors, and you encounter a drug interaction with a different drug, there may be additional risk/complications.However, this is only off investigating dead bodies with comorbidities, so it's not necessarily an accurate representation of the facts.Thanks
