Bone mineral loss seen in men after heart surgery

---

Omschrijving
In the year following coronary artery bypass grafting (CABG), bone mineral content declines significantly in men, according to findings published in the American Journal of Cardiology. Declines in bone mineral have been shown to increase the risk of fracture.Dr. Larry E. Miller, of Virginia Polytechnic Institute and State University, and colleagues evaluated changes in bone mineral and body composition in 26 men, between the ages of 50 and 79 years, who underwent CABG. In each patient, blockages were removed in more than one coronary artery, the blood vessels that pass through the heart to provide oxygen-infused blood to the rest of the body.The investigators performed dual-energy X-ray absorptiometry, a method of measuring bone mineral content, before surgery and at 3 months and 1 year after treatment.Bone mineral density had decreased in the arms, pelvis and the total body by 3 months after treatment. The bone mineral content was also reduced by 4.9 percent in the arms, and losses in the legs and total body approached statistical significance.
