Personal experience, not a vet's.
Cosmo, 17 year old beagle/blue tick mix....heart murmur/cough. He was prescribed Furosemide 20 mg 2x day. Coughing let up. A year later, his coughing got much worse.
So I went to you tube...I learned his potassium might be low. I added a potassium supplement...coughing stopped!!! He is still on the Furosemide for the murmur.
I asked for copies of his blood work from previous tests blood work confirmed his potassium was low...now it's in the middle range :)
