DAYAN EIDLIN, Victor et al. Is it safe to perform coronary artery bypass surgery early after catheterization?. Rev.Urug.Cardiol. [online]. 2016, vol.31, n.1, pp.15-20. ISSN 0797-0048.

Objectives: cardiac surgery performed early after coronariography has been associated with acute renal failure. Nonetheless, there is no solid evidence regarding its association with operative mortality. Our objective was to evaluate the association between early coronary surgery and postoperative outcomes. Methods: patients who underwent isolated coronary artery revascularization between January 2006 and December 2014 were selected from our database. Baseline characteristics were compared between patients who underwent surgery within 24h of coronariography and those in whom surgery was performed afterwards. The following postoperative outcomes were extracted and compared between both groups: operative mortality, time of assisted ventilation, inotrope use, stay in intensive care unit, stay in intensive care unit, and hemodyalisis requirement. Results: we included 2039 patients (early surgery in 382 patients). Patients operated early were younger, less frequently female and with higher incidence of unstable angina and hemodynamic instability. Early surgery was found to be an independent predictor for operative mortality only in patients with preoperative creatinine ³ 1.2 mg/dl (OR=2.81; IC 95% 1.03-7.68). No association was found between early surgery and other postoperative outcomes with the exception of greater use of inotropes. Conclusions: isolated coronary artery revascularization may be safely performed within 24 h of coronariography and does not increase operative mortality in patients with normal preoperative levels of creatinine.
