We therefore conclude that perindopril may offer advantages over enalapril in this particular setting. Administration was at 1200 h in order to avoid the effect of circadian rhythms. The results obtained in our study cannot be attributed to a more aggressive pre-operative diuretic regime in any particular group (Table 1). In our study, intolerance to ACE inhibitors was ultimately determined by an acute adverse event of hypotension and/or oliguria. NLM Post-operative weight loss at day 2 was also similar but in the group with the least haemodynamic tolerance (enalapril group with LVEF <35%) furosemide requirement was greater. The association between preoperative use of angiotensin-converting enzyme (ACE) inhibitors and outcomes after coronary artery bypass grafting (CABG) remain controversial. During ACE inhibitor-induced hypotension, renal function deteriorates in parallel with the decline in renal perfusion and in proportion to the degree of sodium depletion [8],[9]. Corresponding author. van Diepen S, Norris CM, Zheng Y, Nagendran J, Graham MM, Gaete Ortega D, Townsend DR, Ezekowitz JA, Bagshaw SM. Gans and W.H. An increase in serum creatinine occurred after surgery, followed by a subsequent fall to pre-operative levels after the first dose of placebo, perindopril and enalapril (Fig. 2012 Sep;46(9):1239-44. doi: 10.1345/aph.1R128. This site needs JavaScript to work properly. Methods: Postoperative outpatient utilization of ACE inhibitors, statins, and β-blockers was assessed in a cohort of 3,718 patients after CABG 65 years and older. With mild ventricular dysfunction, intolerance to ACE inhibitors occurred in 1 of 20 patients in the perindopril group and 4 of 20 in the enalapril group. Groups were subdivided into those with mild ventricular dysfunction (LVEF=35–65%, n=20) and significant ventricular dysfunction (LVEF<35%, n=7). According to the previous studies, antihypertensive drugs should be withdrawn before surgery. Long term ACE-inhibition in patients after CABG reduces levels of soluble ICAM-1 P.L. Chen S, Acou WJ, Kiuchi MG, Meyer C, Sommer P, Martinek M, Schratter A, Andrea BR, Ling Z, Liu S, Yin Y, Hindricks G, Pürerfellner H, Krucoff MW, Schmidt B, Chun KRJ. 4,5 It has been suggested that all CABG patients be started on ACE inhibitors, … Adverse events during coronary artery bypass graft (CABG) surgery have been described in patients receiving angiotensin converting enzyme (ACE) inhibitors, including hypotension on induction of anaesthesia and an increase in vasoconstrictor requirements after cardiopulmonary bypass (CPB). Hypertension is a frequent condition among patients undergoing CABG, with the majority prescribed beta-blockers and angiotensin-converting enzyme (ACE) inhibitors for the medications' "cardio-protective" features. In-hospital mortality, postoperative myocardial infarction, and stroke were not significantly associated with preoperative ACE inhibitor use. have recently demonstrated the safety of ACE inhibitor treatment prior to CABG. 2015 May;47(5):788-95. doi: 10.1093/ejcts/ezu298. Results: In the groups with mild ventricular dysfunction (LVEF=35–65%) perindopril was discontinued in 1/20 and enalapril in 4/20 patients (P=n.s). Angiotensin-converting enzyme inhibitors have been shown to prolong survival and decrease infarct size in patients after acute coronary syndromes. 2011 Nov;162(5):836-43. doi: 10.1016/j.ahj.2011.07.004. Detailed monitoring of renal function is usually continued until 48 h after surgery in preparation for the patient's discharge on the 4th or 5th post-operative day. Our aim was to study in-hospital outcomes after isolated CABG in patients on preoperative ACE inhibitors. These trials included the study of the high-tissue affinity ACE inhibitors quinapril (in the Quinapril on Vascular Angiotensin-Converting … Drugs were administered within 24 h of the termination of surgery when all inotropes were discontinued. 1b). Morbidity included one occurrence of atrial fibrillation in the placebo group, two occurrences of atrial fibrillation (all requiring cardioversion) and one sternal wound infection in the perindopril group and one chest infection and one resternotomy for haemorrhage in the enalapril group. Background: We sought to evaluate the association between angiotensin-converting enzyme (ACE) inhibitors and outcomes after coronary artery bypass graft surgery (CABG). In our study serum creatinine levels increased in all groups following surgery, but to a lesser degree in the significant dysfunction groups than in the mild dysfunction groups. rights reserved. ACE inhibitors work by blocking hormones that regulate blood vessel constriction. When it comes to holding or continuing with ACE inhibitors before surgery, all bets are off, a perioperative medicine consultant suggested. Veeger, O. Gurné, R.O.B. Overall incidence of MAEs was 38.1% (n = 1,518) in the ACE inhibitor group compared to 33.6% (n = 1,649) in the no-ACE inhibitor group. The larger dose of dopamine required post-operatively prior to the point of entry into the study (mean: 2.2 vs. 0.5 mg/kg per min) may have contributed to this finding.  |  [20] These differences reached statistical significance (P=0.02 between the perindopril and enalapril groups) but because of multiplicities of comparisons these results should be considered with caution. There was also no difference with regard to left ventricular ejection fraction, both for the mild and the significant dysfunction groups. Renal dysfunction after myocardial revascularization: Risk factors, adverse outcomes, and hospital resource utilization. (See "Patient education: Medications for angina (Beyond the Basics)".) Patients were monitored with continuous three-lead electrocardiogram, pulse oximetry, hourly urine output and non-invasive Doppler blood pressure recordings. The first ACE inhibitor, captopril (Capoten), was approved by the FDA in 1981 to lower … Of 8,889 patients, 3,983 (45%) were on preoperative ACE inhibitors and 4,906 (55%) were not. Effects of enalapril on mortality in severe congestive heart failure. Unfortunately, only 30% of our patients were taking ACE inhibitors pre-operatively when these were indicated. doi: 10.1161/JAHA.118.009917. Results were considered to be significant if P<0.05. This is more likely to occur if the ACE inhibitor is administered early after coronary artery bypass grafting (CABG). Risk factors associated with post-operative renal dysfunction include advancing years, diabetes, heart failure, re-operations and raised pre-operative serum creatinine level [23]. Comparison of Angiotensin-Converting Enzyme Inhibitor and Angiotensin Receptor Blocker Management Strategies Before Cardiac Surgery: A Pilot Randomized Controlled Registry Trial. In the present study, we aimed to evaluate the impact of preoperative ACE inhibitor therapy on the incidence of postoperative AKI after CABG on CPB using a risk-adjusted approach. In patients with a history of myocardial infarction long term ACE inhibitor therapy has been shown to result in improved morbidity and mortality [1],[2],[4]. Epub 2016 Jun 20. The purpose of this study was to analyse the haemodynamic tolerance to early post-operative treatment with perindopril and enalapril in patients with impaired renal and ventricular function. 2009;54:1778-1784.Bach DS. Data are the mean±SEM. This phenomenon has been intensively investigated and the wide variation in the reported incidence reflects differences in definition, study design, as well as patient and drug selection [5]. Association of Preoperative Renin-Angiotensin System Inhibitors With Prevention of Postoperative Atrial Fibrillation and Adverse Events: A Systematic Review and Meta-analysis. Conclusion: Our results suggest that after CABG, patients with moderately impaired renal function and significant ventricular dysfunction do not tolerate ACE inhibitors well when these were commenced on the first post-operative day. This is more likely to occur if the ACE inhibitor is administered early after coronary artery bypass grafting (CABG). The impact of angiotensin-converting enzyme inhibitors, statins, and β-blockers after coronary artery bypass graft surgery. The analysis of variance for data before and after ACE inhibitor and placebo administration was a repeated measures ANOVA with Greenhouse–Geiser correction. The purpose of this study was to analyse the haemodynamic tolerance to early post-operative treatment with perindopril and enalapril in patients with impaired renal and ventricular function. van Geel, N.J.G.M. Impact of preoperative angiotensin-converting enzyme inhibitor use on clinical outcomes after cardiac surgery. Effect of preoperative angiotensin-converting enzyme inhibitor on the outcome of coronary artery bypass graft surgery. Cohen Tervaert, P.P. Objective: To examine the effect of ACE inhibition on interleukin 6 (IL-6) concentrations after CABG. However, perindopril was associated with less haemodynamic deterioration than enalapril and consequently may be advantageous in this setting. Epub 2012 Sep 4. Patients and methods: 161 patients undergoing elective first time CABG … Epub 2014 Jul 30. Inotropes are normally discontinued at this point in the patient's progress, while monitoring in a high-dependency bed is such that any problem that may arise is immediately registered and corrective action taken promptly. This first dose hypotensive response was also encountered with perindopril, but in significantly fewer patients. : +356-2595-1738; fax: +356-240-176. Previously, treatment usually started on the 5th post-operative day when renal and myocardial recovery is usually complete. 1 a). Analyses performed after excluding patients with low ejection fractions yielded similar results. With increased awareness of the advantages of these drugs we expect this situation to improve. We do not routinely measure cardiac output after CABG and therefore cannot comment on the effect of ACE inhibitor treatment on cardiac output in this scenario. 1–3 Evidence now exists that ACE inhibitors are effective in decreasing myocardial injury during coronary artery bypass graft surgery (CABG) and can reduce the incidence of ischemic events in the years after surgery. Data are the mean±SE. 2018 Oct 16;7(20):e009917. Angiotensin I converting enzyme inhibitors are now accepted as standard treatment in heart failure as well as in patients with impaired ventricular function following myocardial infarction because several studies have shown them to decrease morbidity and mortality [1],[2],[3],[4]. Enalapril has been widely tested in patients with heart failure [1],[4] and perindopril has been shown to reduce left ventricular hypertrophy [26] and alter peripheral haemodynamics in humans [11],[27] without significant hypotension [28]. Kalavrouziotis explained to heartwire that it had been thought that ACE inhibitors may have some anti-ischemic properties that could benefit CABG … Find all the evidence you need on ACE Inhibitors and (stents or CABG) via the Trip Database. For this reason it is desirable to commence ACE inhibitor treatment at a time when the patient's clinical parameters are closely monitored. Because ACE inhibitors decrease glo-merular perfusion pressure, they … effect of ACE inhibitors on renal function after CABG. van Haelst, J.W. However, it would be advantageous for the cardiac patient to be established on such treatment after surgery and then go on to benefit in the long term. 1.4.7 After an MI, offer people who are intolerant to ACE inhibitors, an ARB instead of an ACE inhibitor. Postoperative anaemia is common, frequently persists for months after CABG surgery and is associated with an impaired outcome. Dopamine treatment appeared to be clinically beneficial in our study in that it resulted in an improvement in blood pressure and urine output.
