Hyperhomocysteinemia - The Biochemical Link Between a Weak Heart and Brittle Bones? |
|
Osteoporosis, chronic heart failure (CHF) and mild to moderate hyperhomocysteinemia (HHCY) can frequently be found in elderly individuals and often occur in the same individual. Due to demographic changes in the number of elderly people the total number of individuals suffering from osteoporosis and/or CHF, and hence the cost to society, will increase dramatically over the next 50 years. Thus, prevention of these diseases by identifying and modifying risk factors is a major issue. Recent large population-based prospective studies suggested HHCY as an independent risk factor for CHF and osteoporosis. However, the mechanisms that link HHCY to CHF and osteoporosis are almost unknown. Moreover, until now both diseases have been considered as independent diseases. The finding that heart and bones share a common biochemical risk factor raises the question if there is a biochemical link between these two diseases? This manuscript reviews the existing literature about HHCY and osteoporosis, about HHCY and CHF, and about possible mechanisms that link HHCY to both diseases. Existing data suggest that HHCY could be a useful paradigm with most interesting therapeutic implications, because HCY lowering therapy could favourably influence the course in CHF and osteoporotic patients. |
