Combining ACE inhibitors with ARBs ___________ mortality.
does not; it does reduce incidence of events, but the benefits do not outweigh the risks

HFrEF patients who cannot tolerate ACE inhibitors
Norepinephrine levels are _________ in CHF.
elevated (those with higher levels have lower survival probability)
Why are ß-blockers given to those with CHF?
Because ß1 receptors are down-regulated, and giving small amounts of ß-blockers causes ß1 to increase, thus improving ejection fraction
