potassium-magnesium-aspartate and Angina-Pectoris

To investigate the protective effects of potassium magnesium aspartate against oxidative stress status and lipid oxidative damage in the patients with angina and arrhythmia due to coronary artery disease, its therapeutic effect on arrhythmia and its possible mechanism.. With single blind protocol, 98 patients with angina and arrhythmia due to coronary artery disease were randomly divided into (1)Experiment group (n = 65), who received routine remedy for coronary heart disease plus potassium magnesium aspartate. (2)Control group (n = 33), who received only routine therapy for coronary heart disease without potassium magnesium aspartate. Reduced glutathione (GSH), oxidized glutathione (GSSG), malondialdehyde (MDA) and oxidized low density lipoprotein (ox-LDL) in plasma of all patients were examined before and one week after treatment, all patients with arrhythmia were equipped with Holter for continuous monitoring of cardiac rhythm.. After one week's treatment, the GSH level in plasma of experiment group and the ratio of GSH and GSSG (GSH/GSSG) were significantly increased comparing with control group (both P<0.01), while GSSG, MDA and ox-LDL levels significantly lowered comparing with control group(all P<0.01). The premature beats diminished 86.5% in experiment group, but the decrease rate in control group was only 47.4% (P<0.01). The improvement in indexes of oxidative stress status (including GSH/GSSG, MDA and ox-LDL) and the reduction of premature beats showed close correlation with each other (all P<0.01). No adverse effects of the drug were found after one week of administration of Potassium magnesium aspartate.. Potassium magnesium aspartate can strikingly improve oxidative stress status and decrease lipid oxidative damage in the patients with coronary heart disease, and the frequent premature beats were also significantly reduced by potassium magnesium aspartate. The analysis of above results reveals an intrinsic relationship between the improvement of oxidative stress status and the good therapeutic effects on frequent premature beats by potassium magnesium aspartate, which may suggest an involvement of oxidative stress in the pathogenesis of arrhythmias.
