3 doctors agree
In brief: They don't
Beta blockers do not increase cardiac output.
If anything, they reduce cardiac output by reducing heart rate and the strength of contraction (contractility).

In brief: They do not per se
In treatment of cardiomyopathy they take strain off the heart so it can heal & regain strength over time and in that way can eventually improve cardiac output = heart rate x stroke volume.
