Heart Failure Risk and Selenium Deficiency

Low plasma selenoprotein P levels are associated with a higher risk of heart failure in a Swedish population [Jujic 2023].

Heart rate
Selenium deficiency in heart failure patients is significantly associated with increased risk of cardiovascular mortality, impaired exercise capacity, and poorer quality of life [Bomer 2020].
Selenoprotein P is the primary protein transporter of selenium in the blood.

Plasma and serum selenoprotein P concentrations are useful biomarkers of selenium status in individuals with relatively low selenium intakes because selenoprotein P responds to different intake forms of selenium [Hurst 2010].

Selenium deficiency – defined as serum selenium concentrations below 70 mcg/L – has been associated with more severe symptoms of heart failure, poorer exercise capacity, and poorer quality of life. Sub-optimal serum selenium concentrations of 70–100 mcg/L have similar adverse associations, suggesting that values less than 100 mcg/L, might be considered abnormal [Bomer 2020]. read more

Selenium and Coenzyme Q10 Supplementation To Prevent Heart Disease

Heart disease prevention. In the KiSel-10 Study, combined supplementation of community living senior citizens for four years with an organic high selenium yeast (200 mcg selenium/day) and Coenzyme Q10 in the ubiquinone form (2 x 100 mg/day) prevented an increase in fibroblast growth factor 23 and reduced the risk of cardiovascular disease [Alehagen Feb 2022].

what is fibroblast growth Factor 23?
Prof. Urban Alehagen
Prof. Urban Alehagen was among the first cardiologists to suspect that low selenium intakes might increase the risk of death from heart disease. He designed and conducted the KiSel-10 Study to test the hypothesis that combined selenium and Coenzyme Q10 supplementation might reduce the risk of cardiovascular disease.

Professor Urban Alehagen explains that fibroblast growth factor 23 is a hormone that is secreted primarily from the osteocytes (i.e., mature bone cells) into the blood. From the blood circulation, the hormone acts on fibroblast growth factor receptors in the heart, intestine, kidney, and parathyroid gland [Alehagen Feb 2022].

Fibroblast growth factor 23 is mainly active in the metabolism of vitamin D and phosphorus. However, there have been reports that indicate an association between increased fibroblast growth factor 23 levels and cardiovascular mortality even in the patients with no sign of kidney disease [Alehagen Feb 2022]. read more

Selenium Deficiency and Heart Failure

Heart failure – the inability of the heart muscle to pump a sufficient quantity of blood out to the body – is a debilitating disease, resulting in shortness of breath, congestion in the lungs, and pooling of blood in the lower extremities. Heart failure is equivalent to diminished quality of life.

Mitochondrion
Depiction of a mitochondrion. The mitochondria in our cells convert energy sources such as fatty acids, glucose, and ketones into ATP energy molecules. Sufficient intakes of micronutrients such as selenium, Coenzyme Q10, and zinc are important for mitochondrial energy production and for antioxidant protection of cells, lipids, proteins, and DNA.

The prognosis for heart failure is poor, and the available medical therapies for patients with heart failure are inadequate. New treatment strategies are needed [Mortensen 2015].

Yin et al have analyzed the data from 39,757 adults in a cross-sectional study from the 2005–2018 US National Health and Nutrition Examination Survey. Their findings suggest that high levels of combined dietary antioxidant micronutrients are associated with decreased prevalence of various forms of cardiovascular disease and that selenium has the greatest contribution to this association [Yin 2022]. read more

Selenium and Coenzyme Q10 Combination

The Swedish cardiologist Dr. Urban Alehagen has written persuasively that there exists a special inter-relationship between selenium and Coenzyme Q10 in the prevention of cardiovascular diseases.

Briefly, Prof. Alehagen, together with the Norwegian professor Jan Aaseth, makes the point that low selenium intakes and status could restrict the cells’ ability to get optimal concentrations of Coenzyme Q10 and that the cells need adequate of Coenzyme Q10 to permit optimal function of selenium [Alehagen & Aaseth 2015a].

The clinical outcomes of the KiSel-10 intervention study in which community living Swedish citizens, average age 78 years, were administered selenium and Coenzyme Q10 daily for four years show that combined selenium and Coenzyme Q10 supplementation, compared to placebo treatment, can be beneficial in populations that have low selenium status: read more
