Effect of calcium supplements on risk of myocardial infarction and

Objective To investigate whether calcium supplements increase the risk.. The likely adverse effect of calcium supplements on cardiovascular.

Prespecified subgroup analyses showed a significant interaction between treatment allocation and dietary calcium intake for myocardial infarction. Calcium treatment was associated with an increased risk of myocardial infarction in people with dietary calcium intake above the median of 805 mg/day (hazard ratio 1.85, 95% confidence interval 1.28 to 2.67) but no increased risk in those with dietary calcium intake below the median (0.98, 0.69 to 1.38, P for interaction 0.01). When the cohort was divided by fifths of dietary calcium intake rounded to the nearest 100 mg/day, the respective hazard ratios (95% confidence intervals) for the effect of calcium treatment on myocardial infarction were 1.18 (0.70 to 2.00) for <500 mg/day, 0.68 (0.39 to 1.18) for 500-699 mg/day, 2.28 (1.26 to 4.15) for 700-899 mg/day, 1.81 (0.97 to 3.41) for mg/day, and 1.41 (0.81 to 2.48) for ≥1100 mg/day; test for linear trend when hazard ratios are expressed relative to the <500 mg/d fifth, P=0.12.

Study adds weight to link between calcium supplements and heart

Study adds weight to link between calcium supplements and heart

The authors suspect that the abrupt change in blood calcium levels after taking a supplement causes the adverse effect, rather than it being.

The Women's Health Initiative (WHI) study -- a seven-year trial of over 36,000 women -- found no cardiovascular effect of taking combined calcium and vitamin D supplements, but the majority of participants were already taking personal calcium supplements, which may have obscured any adverse effects.

So a team of researchers, led by Professor Ian Reid at the University of Auckland, re-analysed the WHI results to provide the best current estimate of the effects of calcium supplements, with or without vitamin D, on the risk of cardiovascular events.

New research published online in the British Medical Journal adds to mounting evidence that calcium supplements increase the risk of cardiovascular events, particularly heart attacks, in older women.

They analysed data from 16,718 women who were not taking personal calcium supplements at the start of the trial and found that those allocated to combined calcium and vitamin D supplements were at an increased risk of cardiovascular events, especially heart attack.

But in an accompanying editorial, Professors Bo Abrahamsen and Opinder Sahota argue that there is insufficient evidence available to support or refute the association.

Clearly further studies are needed and the debate remains ongoing." Story Source:.

If this target is not achievable, calcium supplementation is generally effective, cheap. Occasional adverse effects include constipation, bloating and flatulence.

But why did we ever recommend calcium supplements at all? Did we have any good evidence that they worked? Sort of, but in retrospect, not really.

It doesn’t do much for the image of so-called “science-based medicine” when real doctors buy into and then promote these ephemeral alt-health crazes.

Is there a correlation to the “slip-slop-slap” campaign and the government-promoted paranoia about any citizen being exposed to any sunlight whatsoever? Yes, sunbaking is bad and it’s wonderful that Australia is taking steps to prevent more melanomas, but SOME sun exposure, maybe 20 minutes while walking to school or to the shops, especially before 9am, is not unreasonable for people to get.

“Lots of people are Vitamin D deficient, so many of us that the Australian Government recently queried why testing for Vitamin D has gone through the roof over the last ten years.”

Honestly, if we keep getting fished in by these silly trends, we are acting more and more like a bunch of Dr Oz clones….
