Study provides evidence of a link between osteoporosis and heart disease
by Mike Adams, the Health Ranger, NaturalNews Editor
Dr. Pamela Marcovitz, from William Beaumont Hospital in Royal Oak, led a study of coronary artery disease (CAD) and found that patients suffering from osteoporosis are at an increased risk of developing CAD.
People with the bone-thinning disease osteoporosis are at increased risk for having coronary artery disease (CAD), in which plaque build-up starves the heart of its blood supply, investigators in Michigan report.
In fact, osteoporosis is a stronger factor than some traditional risk markers for CAD.
"A previous study showed that women with osteoporosis have more strokes and cardiovascular events, such as congestive heart failure and chest pain," lead author Dr. Pamela A. Marcovitz told Reuters Health.
With catheterization, doctors inject special contrast material into the body to create an "angiogram" that allows direct visualization of the coronary arteries to determine if blockage is present.
Marcovitz, from William Beaumont Hospital in Royal Oak, and her associates identified 183 women and 26 men who underwent bone testing and catheterization within the same 12-month period between 1999 and 2002.
Patients with CAD were more likely to have brittle bones, the investigators report in the American Journal of Cardiology.
The association was even stronger for those with osteoporosis.
Moreover, after accounting for traditional risk factors, osteoporosis remained a significant predictor of CAD: patients with osteoporosis were nearly six times more likely to have CAD than those without osteoporosis.
Osteoporosis was a stronger risk factor for CAD than high blood sugar levels, high blood pressure, or a family history of early CAD.
No one knows for sure, but cells that cause breakdown of bones, known as osteoclasts, have also been shown to stimulate calcium build-up in arteries, which may contribute to plaque build-up.
The results suggest that "perhaps we should be screening women with (brittle bones) for heart disease," Marcovitz commented, "and maybe we should be treating (brittle bones) more aggressively to see if CAD is improved."
