Araguas MA, Herrera A, Garrido I, et al. - This study was conducted to evaluate whether preoperative levels of brain natriuretic peptide and troponin I were related to early occurrence of major adverse cardio-vascular events (MACE) after osteoporotic hip fracture (OHF) repair surgery.  Researchers prospectively collected perioperative clinical and analytical data from consecutive patients, without known history of cardiovascular disease and undergoing surgery for OHF repair at a single centre during a 6-month period. A total of 140 patients who were included in the study. Though the data need validation in a larger multicentre cohort, distinguishing risk factors for early postoperative MACE after OHF repair surgery, might facilitate measuring patients’ risk prior to and following surgery, and focusing them the appropriate preventive and/or therapeutic interventions.
