In hfpef we use vasconstrictors…why?

Hfpef maney ?

Heart failure preserved ejection fraction… Is it that we want to increase preload coz EF is already maintained or what?

In case of cardiogenic shock

No I am asking about management of chronic heart failure with preserved ejection fraction

And what is prime reason behind usage of vasconstrictors in it?

hocm/RCMP you manage the presentation, in case the sBP is <90, we use ionotropes, diastolic failure will present to you with shock
