PD treatment for severe congestive heart failure.

Our objective was to evaluate if peritoneal dialysis (PD) could improve survival of patients with progressive severe congestive heart failure resistant to drug therapy. The patients were selected by the cardiologist in cooperation with a nephrologist, including patients not responding to conventional medication with an expected fatal outcome within the next months. The study included 16 consecutive patients with a chronic progressive severe refractory heart failure (sHF) of NYHA class III (n = 6) or IV (n = 10) who did not respond to diuretics and angiotension converting enzyme (ACE) inhibitors.

Nutritional magnesium supplementation does not change blood pressure nor serum or muscle potassium and magnesium in untreated hypertension. A double-blind crossover study.

The aim of this study was to evaluate if a nutritional dose of magnesium given orally changes the blood pressure in untreated hypertensive patients and if orally-given magnesium had any influence on serum and muscle magnesium and potassium. A randomized, double-blind crossover study design was followed with magnesium 15 mmol/day or placebo treatment for two months. Thirty-nine patients aged 20-59 years, were treated.
