Saw cardiologist who said no heart failure, BP stable. He said only take lisinopril 5, crestor (rosuvastatin). Is that good? I'm 90. My friends take lots of pills.

That is very good. If you are 90 years old and only taking two pills that is excellent. Lisinopril is a great drug that lowers blood pressure, protects the kidney and may help prevent strokes. Crestor (rosuvastatin) is also a great medication for lowering cholesterol. You need to have periodic blood tests when you are on those drugs but i'm sure your doctors are doing those. Live long & laugh much.
If you were just. Started on Crestor (rosuvastatin) at the age of 90 i would reconsider. Statins are used to reduce the risks of strokes and heart attacks and to reduce the progression of disease, but their benefits, take years to derive. Unless your risks are very high or if your expected life span is more than a few years, i don't believe you would derive much benefit and you can potentially experience unwanted side effects.
