The authors note that interventions geared toward raising vitamin D and lowering CRP levels in heart failure patients are possible, but "it remains unclear whether vitamin D therapy has a role in the management of elderly patients with HF." If it is shown that "vitamin D therapy improves physical performance and modulates the inflammatory response, this could become an attractive therapy for patients with HF."
2011 — New research linking low vitamin D levels with deaths from heart disease and cancer causes, bolsters mounting evidence about the "sunshine" vitamin's role in good health. Scientists have known for ages about vitamin D's role in helping the body absorb calcium, in maintaining bone density, and in preventing osteoporosis
Patients with the lowest blood levels of vitamin D were about four times more likely to die from any cause during the next eight years than those with the highest levels, the study found. The link with heart-related deaths was particularly strong in those with low vitamin D levels.
In another study a link has been found about high blood pressure and vitamin-D deficiency.
Low sexual activity and poor physical performance are linked to vitamin-D deficiency.
For one thing, megadoses of vitamin D pills can help avoid the dangerous diseases and reduce risks of heart disease easily from too much sunshine is well-known.
Low vitamin D levels could reflect age, lack of physical activity and other lifestyle factors detailed below that also affect health, said American Heart Association spokeswoman Alice Lichtenstein, director of the Cardiovascular Nutrition Laboratory at Tufts University.
The study led by Austrian researchers involved 3,258 men and women in southwest Germany. Participants were aged 62 on average, most with heart disease, whose vitamin D levels were checked in weekly blood tests. During roughly eight years of follow-up, 737 died, including 463 from heart-related problems.
