Brief Summary

The dietary supplements selenium and Q10 has been evaluated in a double blind placebo-controlled study in an elderly Swedish population. The hypothesis is that as a majority of Northern Europeans suffers insufficient levels of selenium that is used by the cell in the building of at least 25 different enzyme systems in the body, and that the cell need presence of Q10 in order to produce the selenium containing enzymes, we wanted to evaluate the effect of a combined intervention of the two supplements in an elderly population in Sweden. All participants were controlled every 6 months, and the intervention was 48 months in each participant. Besides blood samples, echocardiography and cardiac natriuretic peptides were analyzed at start, every 6 months and at end of the study.

Outcome Measures

Primary Outcomes (1)

  • Change in cardiovascular and all-cause mortality as effect of intervention

    The cardiovascular and all-cause mortality is registered in the study population and an evaluation effect of intervention in terms of change in mortality will be analyzed

    From start until 48 months of intervention

Secondary Outcomes (1)

  • Change in cardiac function as measured by echocardiography and cardiac natriuretic peptides as effect of the intervention

    From start until 48 months of intervention

Study Arms (2)

sellenium + Q10

EXPERIMENTAL

Active dietary supplement that is compared against a placebo arm

Dietary Supplement: Selenium and ubiquinon (Q10) combined

Sugar pills

PLACEBO COMPARATOR

Placebo arm that is compared against active intervention with a dietary supplement with selenium + Q10

Dietary Supplement: Selenium and ubiquinon (Q10) combined

Interventions

A combination of 200 mg/day of coenzyme Q10 (Bio-Quinon 100 mg B.I.D, Pharma Nord, Vejle, Denmark) and 200 µg/day of organic selenium (SelenoPrecise 200 µg, Pharma Nord), or placebo

Also known as: Bio-Quinon 100mg, SelenoPrecise 200microgr
Sugar pillssellenium + Q10

Eligibility Criteria

Age70 Years - 87 Years
Sexall
Healthy VolunteersYes
Age GroupsOlder Adult (65+)

You may qualify if:

  • All elderly persons living in Kinda Municipality,
  • Sweden aged 70-87, who have accepted participation in the study, and who are expected to fulfill a study period of 4 years.

You may not qualify if:

  • Recent myocardial infarction (within 4 weeks).
  • Planned cardio-vascular operative procedure within 4 weeks.
  • Hesitation concerning if the candidate can decide for him/herself whether to participate in the study or not, or if he/she understands the consequences of participation.
  • Serious disease that substantially reduces survival or where it is not expected that the participant can cooperate for the full 4 year period.
  • Other factors making participation unreasonable, such as long/complicated transport to the Primary Health Center where the project is managed, or drug/alcohol abuse.
