Summary

• Epidemiological studies verified a link between

osteoporosis and cardiovascular disease.

– Patients with osteoporosis are at higher risk for ischemic heart

disease and stroke and, on the other hand, patients with

peripheral arterial disease or ischemic heart disease have a

higher risk of osteoporotic fractures.

• However, further studies are required to investigate

the underlying mechanisms between osteoporosis

and cardiovascular disease.
