magnesium-orotate and Heart-Failure

Metabolic therapy involves the administration of a substance normally found in the body to enhance a metabolic reaction within the cell. This may be achieved in two ways. Firstly, for some systems a substance can be given to achieve greater than normal levels in the body so as to drive an enzymic reaction in a preferred direction. Secondly, metabolic therapy may be used to correct an absolute or relative deficiency of a cellular component. Thus, metabolic therapy differs greatly from most standard cardiovascular pharmacologic therapies such as the use of ACE Inhibitors, beta-blockers, statins and calcium channel antagonists that are given to block rather than enhance cellular processes.

Magnesium orotate dihydrate (MO) has the sum formula C10H6MgN4O8 x 2H2O and a MG of 370.52. The salt is poorly soluble in water and hence does not bind gastric acid nor does it exhibit noteworthy laxative effects upon oral administration in contrast to easily dissociable Mg salts. As a source of magnesium (Mg), MO is indicated for the oral treatment of extracellular Mg deficiency. Orotic acid (OA), the second active ingredient of MO, is a key intermediate in the biosynthetic pathway of pyrimidines and is shown to improve the energy status of injured myocardium by stimulating, a.o., the synthesis of glycogen and ATP. Myocardial energy-rich phosphate levels are decreased during hypoxic conditions; subsequently, intracellular Mg is depleted and lost via the urine. Since binding sites for Mg (ATP) are provided by OA it can be classified as "Mg-fixing agent". Accordingly MO is also indicated for the treatment of Mg depletion as convincingly shown in animal experiments and also in coronary heart patients undergoing e.g. aortocoronary bypass surgery.

Aim of this study was to evaluate adjuvant magnesium orotate on mortality and clinical symptoms in patients with severe heart failure under optimal cardiovascular medication.. In a monocentric, controlled, double-blind study, 79 patients with severe congestive heart failure (NYHA IV) under optimal medical cardiovascular treatment were randomised to receive either magnesium orotate (6000 mg for 1 month, 3000 mg for about 11 months, n = 40) or placebo (n = 39). Both groups were comparable in demographic data, duration of heart failure and pre- and concomitant treatment.. After mean treatment duration of 1 year (magnesium orotate: 364.1 +/- 14.7 days, placebo: 361.2 +/- 12.7 days) the survival rate was 75.7% compared to 51.6% under placebo (p < 0.05). Clinical symptoms improved in 38.5% of patients under magnesium orotate, whereas they deteriorated in 56.3% of patients under placebo (p < 0.001).. Magnesium orotate may be used as adjuvant therapy in patients on optimal treatment for severe congestive heart failure, increasing survival rate and improving clinical symptoms and patient's quality of life.

In a pilot study at 14 patients with coronary heart disease (CHD) and left-ventricular dysfunction (left ventricular enddiastolic volume [LVEDV] > or = 100 ml), who actively participated in an ambulatory cardiac sports group, left ventricular endsystolic volume (LVESV), LVEDV and duration of exercise were analyzed by echocardiographic and ergometric tests. An initial workup was followed by a 4 week double blind treatment phase, in which magnesium orotate 3 x 1 g or placebo was given additionally to medication taken prior to the study. At the end of this phase a concluding workup was performed. Magnesium orotate decreased significantly (p = 0.016) LVESV, increased significantly (p = 0.035) EF, decreased in tendency (p = 0.054) LVEDV and increased significantly (p = 0.011) exercise duration. The study gives references to favourable effects of oral magnesium orotate to left ventricular function and exercise tolerance in patients with CHD.

This study deals with the potential therapeutic effect of orotic acid (OA) and Mg Orotate (MgO) on myocardial degeneration and the development of congestive heart failure in cardiomyopathic (CM) hamsters of the UM-X7.1 line. Two major age groups (group I, < 30 days and group II, > 180 days old) were used in these experiments, which lasted 30 and 50 days, respectively; the orotic salts were incorporated (10%) into Purina Lab Chow given ad libitum. Macroscopic and microscopic assessment of pathologic changes together with ECG recordings revealed that MgO treatment significantly reduces myocardial damage, especially the severity of calcific changes. ECG recordings clearly demonstrated a significant shortening of QTc and PR intervals, resulting in partial electrical stabilization of failing hearts, with a significant delay in systemic congestive changes. The prevention of heart lesions was less evident in animals receiving OA, but both preparations proved to be equally efficient in prolonging survival of the CM hamsters.
