hi -- i've just had two new cardiologists - first one is an EX cardiologist b/cuz for one thing she rxd metoprolol succinate at 100 mgs twice a day. i have low blood pressure sometimes but sometimes it's high like around 143 systolic. so i knew that 200 mg metoprolol a day was too much for me -- e.g. i'd end up on the floor after fainting (or worse) from dangerously low b.p. i now take 25 mg one or 2 x a day. and i do try to be checking my b.p. and heart rate. also the ex-cardiologist pushed me off to an NP after my 1st appt. i did not know ANYTHING about said NP, not even her name much less her qualifications/clinical experience. and when said NP sent me a stupid reply to a question i had posed to the MD i was both disappointed and angry b/cuz i was not getting the care i need and expected from the cardiologist. so i changed to another cardiologist in the same group. he seems ok but i'm not sure yet. i did ask a couple questions via the electronic portal -- cardiologist 2 answered vaguely e.g. no real answer. i am concerned about the BNP levels which were over 1000 sometimes. cardiologist 2 said it's best to talk about it at next appt. i also asked what the metoprolol and losartan are doing for my heart failure? he answered w. an empty answer. so i'll see how he is at my next appt. coming up next week.
