NCT03840226

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Improvement in exercise duration time

    Improvement in 6-minute walking testing (any improvemnt of length in meters from baseline). The outcome will be measured in meters and the higher is better from baseline. A 10% higher distance from baseline will be considered significant improvement.

    1 year

  • Qaulity of life

    Improvement in quality of life by Minisota living with Heart Failure Questionnaire. The scale is in points and the higher scale the better. Any improvement in at least 10% from baseline will be considered a significant improvement.

    1 year

Secondary Outcomes (1)

  • Improvment in the number of hospitalizations for heart failure

    1 year

Model Details: The aim of the study is to test The impact of magnum versus placebo, on six-minute and clinical outcomes of patients with CHF (level 2-4). The Primary endpoints are: 1. Improvement in Six-Minute walk test. 2. Improvement in clinical outcomes: death, CHF hospitalization, revascularization etc. To test the hypothesis that the six-minute results between the two study groups are different, with significance level of 5% and power of at least 80%, we use the t-test. Based on Monica et al (2001), the mean six-minute results among these patients is 218 with SD=28. for an expected difference of at least 10 meter, we need a sample size of 125 patients in each group.
