Unlabelled: The aim of this study was to evaluate the gender-oriented differences in the outcomes of a lifestyle intervention trial (diet, smoking cessation, and exercise) among patients who had open heart surgery. A randomized, nonblind intervention study was performed on 500 patients who had open heart surgery. Immediately after hospital discharge, 250 patients were randomly allocated lifestyle intervention by receiving oral and written information in the form of a booklet with specific educational information for postoperative rehabilitation. The remaining 250 patients received the regular oral instructions. The applied lifestyle intervention proved to be beneficial only in men as far as quitting smoking (relative risk [RR]: 0.36, confidence interval [CI]: 0.16-0.80; P = .01) and returning to work (RR: 0.35, CI: 0.13-0.92; P = .03) are concerned. For both genders, no significant associations between dietary and physical activity recommendations were observed., Conclusion: Lifestyle nursing intervention immediately after open heart surgery had a beneficial effect on men 1 year after the surgery but not on women. Thus, there is a need for gender-specific studies among women., (© The Author(s) 2015.)

Background: Patients with preoperatively diagnosed type II heparin-induced thrombocytopenia (HIT) scheduled for cardiopulmonary bypass (CPB) present a challenge in their intraoperative anticoagulation management because re-exposure to heparin may result in profound thrombocytopenia, intravascular thromboses, bleeding, and even death. Iloprost, a prostacyclin analogue that reversibly inhibits platelet aggregation, has been suggested as a management approach in such cases. The purpose of this study was to assess and confirm the efficacy of a perioperative intravenous iloprost infusion in preventing thromboembolic complications in patients with type II HIT undergoing cardiac surgery and requiring the use of heparin and CPB., Methods: During a one-and-a-half-year period, 22 patients with type II HIT presented at the Cardiac Surgery Service of the Onassis Cardiac Center in Athens. In these patients, platelet aggregation test results were found strongly positive at heparin serum concentrations corresponding to those achieved during CPB. Iloprost was used in a preoperatively, in vitro-determined, patient-specific concentration that was assessed and modified perioperatively depending on its in vivo effect on platelet aggregation as opposed to the conventional constant rate., Results: In the 22 patients, the preoperatively determined concentration of iloprost seemed to correlate well with the in vivo interruption of platelet aggregation, as tested by a perioperative heparin-induced platelet aggregation (HIPA) assay, and in only 3 cases (14%) was the rate of iloprost infusion increased. The patients' platelet counts, which were evaluated peri- and postoperatively, were preserved with no statistically significant fluctuations. Postoperative bleeding was within normal limits and no thrombotic episodes or other complications were reported., Conclusion: Although a number of alternative anticoagulation methods, such as the use of another anticoagulant (danaparoid sodium and recombinant hirudin) or the preoperative use of a defibrinogenating agent (ancorod), have been suggested for patients with type II HIT requiring anticoagulation during CPB, the use of heparin associated with a potent platelet inhibitor such as the prostacyclin analog iloprost is, as this study confirmed, the only to-date safe and effective choice.
