INVESTIGATION OF BONE MINERALIZATION IN PATIENTS WITH CORONARY HEART DISEASE COMPLICATED BY CHRONIC HEART FAILURE, STAGE II-A.

The majority of the studies have shown that individuals with cardiovascular diseases have a higher risk of experiencing bone loss and thus greater predisposition to risk of fracture. On the other hand there is growing evidence that individuals with low bone mass have higher mortality for cardiovascular events compared to patients with cardiovascular disease with normal bone mass. This research aims to investigate bone mineralization in patients with coronary heart disease complicated by stage II-A chronic heart failure. The study involved 33 men with coronary heart disease complicated by Stage II-A chronic heart failure. Bone mineral density was measured using dual energy x-ray densitometry of lumbar region of spine. Structural and functional changes of bone tissue of the lumbar spine have been found in 49,2% patients with coronary heart disease complicated by Stage II-A chronic heart failure, in particular, I stage of osteopenia - in 44,6%, II stage of osteopenia - in 27,7%, III stage of osteopenia - in 10,8% and osteoporosis - in 16,9%. It was established the same type of downward trend for BMD decreasing in L1 of patients with different stages of osteopenia, but in case of osteoporosis mineralization decreased equally in all vertebrae.
