Cardiac performance and coenzyme Q10 in thyroid disorders.

H Suzuki, T Naitoh, S Kuniyoshi

    Endocrinologia Japonica
    |December 1, 1984
    PubMed
    Summary

    Serum Coenzyme Q10 levels are inversely correlated with thyroid hormones. Supplementation improved cardiac performance in hyperthyroid patients, suggesting therapeutic value for thyrotoxicosis-induced heart failure.

    Area of Science:

    • Cardiology
    • Endocrinology
    • Nutritional Science

    Background:

    • Thyroid disorders, such as hyperthyroidism and hypothyroidism, can significantly impact cardiac function.
    • Serum levels of Coenzyme Q10 (CoQ10) may be altered in patients with thyroid dysfunction.
    • Cardiac performance is a critical indicator of cardiovascular health, particularly in endocrine-related conditions.

    Purpose of the Study:

    • To examine the relationship between serum Coenzyme Q10 levels and cardiac performance in individuals with thyroid disorders.
    • To assess the effect of Coenzyme Q10 supplementation on cardiac function in hyperthyroid patients.

    Main Methods:

    • Serum thyroid hormones and Coenzyme Q10 levels were measured in hyperthyroid, hypothyroid, and normal subjects.
    • Cardiac performance was evaluated in these groups.

  • A subset of hyperthyroid patients received daily Coenzyme Q10 (120 mg) for one week, with subsequent assessment of cardiac performance.

    • Main Results:

    • A significant inverse correlation was observed between thyroid hormone levels and serum Coenzyme Q10.
    • Hyperthyroid patients exhibited lower serum Coenzyme Q10 levels compared to controls.
    • Coenzyme Q10 supplementation led to further augmentation of cardiac performance in hyperthyroid patients.

    Conclusions:

    • Serum Coenzyme Q10 levels are closely linked to thyroid hormone status.
    • Coenzyme Q10 supplementation demonstrates therapeutic potential for managing cardiac dysfunction in severe hyperthyroidism.
    • These findings highlight the role of Coenzyme Q10 in cardiovascular health within the context of thyroid disorders.
