CCB possess negative inotropy... The weaker contractions... Heart failure worsens... Also, BB are not recommended in acute HF decompensation-- should decrease the dose to min... Also can worsen HF... The dose reduction only in decompensation.. After reaching euvolemia, go back to the max tolerated BB dose in HF...

beta blockers increase longevity
but they should be used cautiously in acute decompensated systolic HF

CCB are negative inotropes without any proven mortality benefit
so why risk the patient's compromised EF further ?

CCBs also cause peripheral vasodilation (ALL of them at different levels) which may cause reflex tachicardia and increase oxygen demand.
