Bloodwork After HF Diagnosis

After being diagnosed with reduced EF, I was started on Carvedilol, Farxiga & Entresto. A week later I had a heart cath and when they did bloodwork they noticed my kidney function wasn’t 100% and my potassium was low (3.0).

From what I’ve read, low potassium significantly increases the risk of dangerous heart rhythms and that most doctors usually do bloodwork 3-4 weeks after starting HF meds to make sure the kidneys are handling it well.

What has been everyone’s experience with bloodwork after starting meds? Did you have follow up bloodwork done? Has anyone had low potassium and if so, how did your dr handle it?

I have a cardiac MRI scheduled for the end of next month, which will be three months since my diagnosis. My next cardiologist appointment isn’t until after the MRI to go over results, so I know I will be going at least 3 months with no follow up bloodwork to check kidney function or potassium levels.
