The Impact of Magnesium on Exercise Tolerance, Quality of Life & Clinical

Status Recruiting

Clinical Trial Summary

Magnesium supplementation could improve cardiac performance. Patients with chronic heart failure (CHF) are magnesium deficient and we hypothesized that 1 year supplementation of oral magnesium comparted to placebo will improve exercise duration time and quality of life.

Clinical Trial Description

Magnesium supplementation improves myocardial metabolism, inhibits calcium accumulation and myocardial cell death; it improves vascular tone, peripheral vascular resistance, afterload and cardiac output, reduces cardiac arrhythmias and improves lipid metabolism. Magnesium also reduces vulnerability to oxygen-derived free radicals, improves human endothelial function and inhibits platelet function. Patients with chronic heart failure (CHF) are magnesium deficient. The activation of the renin-angiotensin-aldosterone system and the use of diuretics are associated with depletion of potassium and magnesium in CHF. Magnesium deficiency stimulates aldosterone production and secretion, while magnesium infusion decreases aldosterone production production by inhibiting cellular calcium influx. Adamopoulos et al recently found that CHF in patients [mainly New York Heart Association (NYHA) II-II] with low serum magnesium ≤ 2 mEq/L was associated with increased cardiovascular mortality (but had no association with cardiovascular hospitalization) compared to those with serum magnesium > 2 mEq/L in a long-term follow-up of 36 months, suggesting that most of these deaths were likely sudden (arrhythmic) in nature. Furthermore, Stepura and Martynow demonstrated that oral magnesium orotate used as adjuvant therapy in severe NYHA IV CHF patients increased 1-year survival rate and improved clinical symptoms and patient's quality of life compared to placebo. The investigators hypothesized that 1-year supplementation of oral magnesium compared to placebo to CHF patients will improve exercise duration time and quality of life. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
