Bone mineral density, bone remodeling and osteoprotegerin in patients with acute coronary syndrome

Producción CientíficaThe 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. Eightythree 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-κB 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

Valor pronóstico de los anticuerpos anti-Chlamydia pneumoniae en la cardiopatía isquémica

Producción CientíficaSe ha relacionado la enfermedad arterial coronaria con infección por Chlamydia pneumoniae, pero existen pocos estudios que valoren la presencia de anticuerpos frente a este microorganismo y el pronóstico de los pacientes con cardiopatía isquémica. El objetivo de nuestro estudio fue valorar el impacto de la positividad de anticuerpos anti-Chlamydia pneumoniae en la morbimortalidad asociada a la cardiopatía isquémica
