1) High inotropy might change with the institution of other drugs. Introduce CCB first and secondly thiazide if the patient is normovolemic. In reverse order if the patient is hypervolemic and with normal vascular resistance. Therefore high inotropy should only be treated with carvedilol if 1) the patient is receiving ACE inhibitor, thiazide and CCB and the impedance measure of high inotropy is made after ACE-inhibitor, thiazide and CCB is started.
