Bone mineral density, bone remodeling and osteoprotegerin in patients with acute coronary syndrome
Abstract:
The objective of this study was to evaluate the relationship between coronary disease and osteoporosis and determine the effect of osteoprotegerin (OPG) on bone remodeling and bone mineral density (BMD) in a group of patients with acute coronary syndrome. Eighty-three patients (52 males and 31 women) with acute coronary syndrome (75 patients with acute myocardial infarction and 8 with unstable angina) with an average age of 61+/-10 years were studied. Levels of osteocalcin, urinarydeoxypyridinoline, OPG and the receptor activator of nuclear factor-kappaB ligand (RANKL) were determined during the hospital stay. Femoral neck, trochanter and lumbar spine densitometry was carried out using a DXA densitometer. Thirty percent of patients presented osteoporosis (39% of females and 26% of males). Osteoporotic patients were older and had a lower weight and height and elevated serum levels of osteocalcin (3.6+/-2.25 2.63 versus +/-1.55, p=0.05). Levels of OPG and RANKL were similar in both groups and showed no relationship with BMD. In conclusion, no relationship was observed between the OPG/RANKL system and BMD in these patients.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
