High intake of supplemental calcium associated with excess CVD death in men but not women

High intake of supplemental calcium associated with excess CVD death in men but not women | Heart diseases and Heart Conditions | Scoop.it

Importance Calcium intake has been promoted because of its proposed benefit on bone health, particularly among the older population. However, concerns have been raised about the potential adverse effect of high calcium intake on cardiovascular health.

 

Objective To investigate whether intake of dietary and supplemental calcium is associated with mortality from total cardiovascular disease (CVD), heart disease, and cerebrovascular diseases.

 

Results During a mean of 12 years of follow-up, 7904 and 3874 CVD deaths in men and women, respectively, were identified. Supplements containing calcium were used by 51% of men and 70% of women. In men, supplemental calcium intake was associated with an elevated risk of CVD death (RR>1000 vs 0 mg/d, 1.20; 95% CI, 1.05-1.36), more specifically with heart disease death (RR, 1.19; 95% CI, 1.03-1.37) but not significantly with cerebrovascular disease death (RR, 1.14; 95% CI, 0.81-1.61). In women, supplemental calcium intake was not associated with CVD death (RR, 1.06; 95% CI, 0.96-1.18), heart disease death (1.05; 0.93-1.18), or cerebrovascular disease death (1.08; 0.87-1.33). Dietary calcium intake was unrelated to CVD death in either men or women.

 

Conclusions and Relevance Our findings suggest that high intake of supplemental calcium is associated with an excess risk of CVD death in men but not in women. Additional studies are needed to investigate the effect of supplemental calcium use beyond bone health.

Thre has been concern that the risks of taking calcium supplements may exceed the benefits in some patients. The "hardening of the arteries" that causes vascular problems such as heart attack, stroke and gangrene, is caused by calcium deposits (vascular calcification).  Taking high doses of calcium raises the available calcium in the blood vessles for deposit in the artery wall and the calcium may not be incorporated in the bones which is the goal of treatment.  The recommendation that men consider avoiding calciu supplemetns is reasonable.

Vitamins Herbal & Natural - A Cardiologists Perspective

Pentucket Medical cardiologists Seth Bilazarian and Sunny Srivastava discuss vitamins and dietary supplements as alternative, complimentary and natural therapies.

Patients often think doctors are "against" the use of vitamin or herbal therapies.  I try to explain on our community program "Matters of the Heart"  the doctors viewpoint on Vitamin supplements - cautions and recommendations.  I speak about Vitamin D deficiency and its treatment.

Because its a VItamin or because it says its natural doesn't mean its good.
