For less side effects and less potassium loss I'g go with hydrochlorothiazide.
For instantaneous large water loss, I'd go with Lasix (furosemide)...I think they call it Frusemide in the UK. Go with 40 mg. twice a day. With Lasix you should take 20 Meq's (about 800 mg) KCl.

For noticeable edema, I think the latter is the better choice.

oceanview,

Two choices for diuretic:
HCTZ (hydrochlorothiazide)...lowers sodium and water slowly. Little potassium loss but high sodium loss.
Lasix (furosemide) probably called frusemide in the UK. Large postassium loss, little sodium loss. Should be taken with KCl 20 Meq (about 800 mg.) At a dose of 40 mg. twice a day, you will lose any water retention very quickly.

Nuclear stress perfusion test might be called a Sestamibi Scan, or a MIBI scan, or a nuclear stress test...all the same thing. An isotope is injected into your bloodstream and the distribution is mapped on a scanner. Areas of the heart without radiation are being starved of blood.

Ocean,

Two choices of diuretic:

Hydrochlorothiazide...easy on postasssium but significant sodium loss.

Lasix (furosemide) probaly Frusemide in the UK...fast water dump, potassium loss requires supplementation with KCl every day (like 20 Meq). Doseage of 40 mg twice a day will blow off edema fast.

Stress perfusion teat goes by the alternate names: sestamibi scan, MIBI scan, thallium-stress test, nuclear stress test. All involve injection of a radioactive isotope into the bloodstream. A scan shows areas of the hearts with no radiation which are areas that are not getting a sufficient blood flow.

Apologies for the three posts: The first two went "into the ether" and disappeared...or so I though. Then all three reappeared. I think I'll stick to my morning postings:D:D:D
