Popis: | Background: There is controversy over the potential benefits/harms of the usage of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) as regards the postoperative mortality of coronary artery bypass grafting (CABG). This study investigates the correlation between the in-hospital mortality of CABG and the preoperative administration of ACEI/ARB. Methods: Out of 10055 consecutive patients with isolated CABG from 2006 to 2009, 4664 (46.38%) patients received preoperative ACEI/ARB. Data were gathered from the Cardiac Surgery Registry of Tehran Heart Center. In-hospital mortality was defined as death within the same admission for surgery. Adjusted for confounders, multivariable logistic regression models were used to evaluate the impact of preoperative ACEI/ARB therapy on in-hospital death. Results: The mean age of the patients was 60.04 ± 9.51 years and 7364 (73.23%) were male. Eighty-seven (0.86%) patients expired within 30 days. Multivariate analysis revealed that the administration of ACEI/ARB significantly protected against in-hospital deaths inasmuch as there were 33 (0.70%) vs. 54 (1.0%) deaths in the ACEI/ARB positive and negative groups, respectively (OR: 0.628; p value = 0.09). Patients without ACEI/ARB were more likely to have a higher global ejection fraction. Conclusion: Preoperative ACEI usage in patients undergoing CABG can be associated with decreased in-hospital mortality. Large-scale randomized clinical trials are suggested. |
