Water retention in the legs usually mean right side heart failure. Whether caused by the valve and by a plugged artery is what I am wondering? Has he had an angiogram? Echocardiograms do not always show everything. If he has not had an angiogram, he should. If it's a plugged artery, surgeons can put a stent in and he will feel a lot better.
Hello and welcome to the forum. We're glad you found us, but sorry for the circumstances that bring you here. The questions on this forum are not answered by doctors. Rather, they are asked and answered by patients, caregivers and friends.
Do you know the classification of Heart Failure?
Digoxin is a commonly prescribed medication for patients with heart failure, afib/flutter or fast heart rhythms. Doxazosin can be prescribed alone, or in combination with other medications to treat high blood pressure.
Furosemide is a diuretic, used to treat fluid retention as a result of heart failure.
Warfarin is used to prevent blood clots, and is often prescribed for patients with afib (though it is also used for other reasons).
Simvastatin is used to treat patients with elevated cholesterol.
Ramipril is an ACE inhibitor, commonly used to treat heart failure and high blood pressure.
It appears that your friend has been prescribed a number of medications to treat his heart failure, afib and elevated BP. Whether they are the optimal medications is something a doctor would need to determine. In the U.S., coreg is a very common medication prescribed to CHF patients....not sure if it is available in the UK.
As to the atenolol, has anyone asked the doctor whether it would be worth trying it again? Although given the CHF, his new regime may actually be better for him. Given the development of CHF after the change in medication, I'd also want to know if the change was a mitigating factor.
Make sure your friend is limiting sodium and fluid intake. It is very important for CHF patents to watch their sodium and fluids. Perhaps his physician would recommend an appropriate cardiac rehabilitation program at your local hospital or wellness center.
Has he had a stress test? My Dad has CHF and beside an echo, he has a yearly stress test. He also had bypass surgery, so that may be the reason for the stress test....Still, it might be worth asking about.
