Brief Summary

Coronavirus disease (COVID-19) related pneumonia significantly impact patients with underlying cardiovascular (CV) conditions. Animal studies suggest that drugs commonly used to treated CV diseases may increase the ability of COVID-19 to infect cells. The RAAS-COVID-19 trial aims to assess whether temporarily holding these CV drugs in patients who are admitted with COVID-19, versus continuing them, in patients admitted with COVID-19 can impact short term outcomes.

Detailed Description

Open-label, pragmatic, randomized, study of approximately 40 adults. The following groups of participants will be considered: i) within 48 hours of diagnosis of COVID-19; ii) who have received a diagnosis of COVID-19 from another facility and are within 48 hours of transfer to a study recruitment site (Royal Victoria Hospital, Montreal General Hospital, and Jewish General Hospital \[all in Montreal, Quebec, Canada\]). Participants will be randomized 1:1 to an upfront temporary discontinuation) of RAAS inhibition for the duration of the hospitalization (and to consider re-initiate after day 7 of admission or on discharge) versus a strategy continuation of RAAS inhibition. Re-initiation of held RAAS inhibition will be based on treating team's clinical judgement. The RAAS-COVID-19 RCT will evaluate whether an upfront strategy of temporary discontinuation of RAAS inhibition compared to the continuation of RAAS inhibition among patients admitted with established COVID-19 infection and on chronic RAAS inhibition therapy impacts short term clinical outcomes and biomarkers.

Primary Outcome Measures
NameTimeMethod
Global rank scoreBaseline - day 7

The primary end point is a global rank score which is applied to all participants. The global rank sum is based on the following endpoints (and corresponding score): Death (7); Transfer to ICU for Invasive ventilation (6); Transfer to ICU for other indication (5); Non-fatal MACE (Any of the following - MI, Stroke, Acute HF, new onset Afib) (4); Length of stay \> 4 days (3); Development of acute kidney injury (\>40% decline in eGFR or doubling of serum Cr) (2); Urgent intravenous treatment for high blood pressure/hypertensive crisis (2); \>30% Increase in baseline high sensitivity troponin (1); \>30% increase in baseline BNP (1); Increase in baseline CRP to 48 hours \>30%(1); Lymphocyte count drop \>30% (1).

The primary endpoint will be assessed from baseline to day 7 (or day of discharge if occurs before day 7). Participants will receive a weighted score depending on the events experienced. The global rank sum score will then be averaged and compared between treatment arms.
