All ACE inhibitors have demonstrated efficacy in the management of hypertension and are approved by the Food and Drug Administration for this purpose. Data are the mean±SE. 2015 May;47(5):788-95. doi: 10.1093/ejcts/ezu298. 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. However, in their study, patients were restarted on ACE inhibitor treatment 3 months after surgery . Post-operative stay on the ward (following one night on intensive care) was 4.2±0.3 days for the placebo group, 4.3±0.3 days for the perindopril group and 4.2±0.2 days for the enalapril group. The association between preoperative use of angiotensin-converting enzyme (ACE) inhibitors and outcomes after coronary artery bypass grafting (CABG) remain controversial. Daily creatinine levels were not helpful in altering our clinical management as they reflected the clinical course over the previous 24 h and bore no correlation with the acute events. Ischemic events include death, repeat bypass surgery, angioplasty or stent placement, heart attack, ischemic stroke, transient ischemic attack (TIA), or recurrence of angina. However, in the groups with significant ventricular dysfunction (LVEF<35%) perindopril was discontinued in 2/7 and enalapril in 7/7 patients (P=0.02). Enalapril has been widely tested in patients with heart failure , and perindopril has been shown to reduce left ventricular hypertrophy  and alter peripheral haemodynamics in humans , without significant hypotension . Endovasc. Non-pulsatile blood flow, inflammatory mediators, increased catecholamine levels, microemboli, and haemolysis all contribute to renal dysfunction ,,,. NIH Objective: To examine the effect of ACE inhibition on interleukin 6 (IL-6) concentrations after CABG. There were no peri-operative deaths. In our study enalapril resulted in a significant drop in blood pressure and a temporary deterioration in renal function which was corrected with dopamine. Oliguria (<0.5 ml/kg per h) was treated with intravenous furosemide (20 mg) and repeated as necessary. Angiotensin converting enzyme inhibitors: scientific basis for clinical use. This is more likely to occur if the ACE inhibitor is administered early after coronary artery bypass grafting (CABG). Fisher's exact test was used in the analysis of intolerance, with pair-wise comparisons applied within each sub-group. In such cases ACE inhibitor treatment was discontinued and patients commenced on dopamine. Long term ACE-inhibition in patients after CABG reduces levels of soluble ICAM-1 P.L. 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. Are there significant clinical differences? Effect of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers on risk of atrial fibrillation before coronary artery bypass grafting. The incidence of renal dysfunction and dialysis requirement after cardiopulmonary bypass varies widely in different studies ,,. Patients were managed on the high-dependency section of our ward according to strict pre-defined criteria. Dopamine treatment appeared to be clinically beneficial in our study in that it resulted in an improvement in blood pressure and urine output. We therefore conclude that perindopril may offer advantages over enalapril in this particular setting. 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. The first ACE inhibitor, captopril (Capoten), was approved by the FDA in 1981 to lower … Effect of captopril on mortality and morbidity in patients with left ventricular dysfunction after myocardial infarction: results of the survival and ventricular enlargement trial. Ramsay JG. doi: 10.1161/JAHA.118.009917. Effect of ramipril on mortality and morbidity of survivors of acute myocardial infarction with clinical evidence of heart failure.

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. 2012 Sep;46(9):1239-44. doi: 10.1345/aph.1R128. Eighty one consecutive patients undergoing routine CABG with a history of previous myocardial infarction, impaired left ventricular function and impaired renal function (creatinine 110–150 μmol/l) were studied. 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 Gilst Eur. This provides a window of opportunity that is lost on the second post-operative day when invasive lines are removed. There is no convincing evidence that it is effective when administered prophylactically after elective coronary artery bypass grafting . Pfeffer MA, Braunwald E, Moye LA, Basta L, Brown EJ Jr, Cuddy TE, Davis BR, Geltman EM, Goldman S, Flaker GC, et al., (on behalf of the SAVE investigators). ACE inhibitors work by blocking hormones that regulate blood vessel constriction. 2019 May 3;2(5):e194934. Exclusion criteria included oliguria (<0.5 ml/kg per h) or inotrope dependance at the point of entry on the first post-operative day. Coronary revascularization with coronary artery bypass graft (CABG) surgery improves the long term survival in patients with diabetes and multi-vessel disease. In our study, intolerance to ACE inhibitors was ultimately determined by an acute adverse event of hypotension and/or oliguria. Double-blind comparison of perindopril and captopril in hypertension: effects on left ventricular morphology and function, Systemic and regional haemodynamic effects of perindopril in congestive heart failure, Efficacy and acceptability of perindopril in mild to moderate chronic congestive heart failure, Influence of age on the pharmacokinetics and pharmacodynamics of perindopril. A large randomized trial is needed to confirm this finding. Clipboard, Search History, and several other advanced features are temporarily unavailable. Patients with a history of myocardial infarction and with impaired ventricular function were further classified into mild left ventricular dysfunction (35–65% ejection fraction by ventriculography) and significant left ventricular dysfunction (<35%). There was also no difference with regard to left ventricular ejection fraction, both for the mild and the significant dysfunction groups. Creatinine levels before and after surgery (post-operative day 1 and post-operative day 2) in the groups with mild ventricular dysfunction (a) and with significant ventricular dysfunction (b). Because ACE inhibitors decrease glo-merular perfusion pressure, they … Patients' medication is unlikely to be altered by the primary care physician after discharge from hospital.
