In patients with mildly to moderately depressed LV function, the poorer the LV function, the greater was the potential advantage of CABG surgery. Patients with treated LDL cholesterol should have their low-fat diet and cholesterol-lowering medications continued after bypass surgery to reduce subsequent graft attrition. CABG vs PTCA: Randomized Controlled Trials. Aspirin has traditionally been the first line therapy; however, aspirin resist… During this time, you may be attached to various tubes, drips and drains that provide you with fluids, and allow blood and urine to drain away. Of the 953 subjects, 345 (36.2%) received clopidogrel post CABG prior to discharge. Avoidance of homologous blood transfusions after CABG may reduce the risk of both viral and bacterial infections. The guidelines, updated every few years, provide guidance on whether or not a patient should undergo bypass or have non-surgical treatment for heart disease . Lack of social participation and low religious strength are independent predictors of death in elderly patients undergoing CABG. Although themajority resolve spontaneously, post-CABG effusions can persist. However, for the Bypass Angioplasty Revascularization Investigation (BARI) trial, bypass patients had a 5-year survival of 89.3% compared with 86.3% for angioplasty. The aspirin should be started within 24 hours after surgery because its benefit on saphenous vein graft patency is lost when begun later. Dosing regimens from as little as 100 mg/d to as much as 325 mg TID appear to be efficacious. Risk of Postoperative Renal Dysfunction (PRD) After Coronary Artery Bypass Graft Surgery. Thus, early reinitiation of β-blockers is critical for avoidance of this complication. Finally, medically assigned patients crossed over to surgery late, thus allowing the highest-risk medically assigned patients to gain from the benefit of surgery later in the course of follow-up. Ongoing ischemia or threatened occlusion with significant myocardium at risk. The benefit of surgery for left main coronary artery disease patients continued well beyond 10 years. 1-800-AHA-USA-1 A fourth area that is rapidly evolving is transmyocardial revascularization. For patients randomized to angioplasty, CABG was needed in ≈6% during the index hospitalization and in nearly 20% by 1 year. For the most part, stratification of patients in the trials was based on the number of vessels with anatomically significant disease, whether or not the major epicardial obstruction was proximal, and the extent of LV dysfunction as determined by global EF. One approach to reduce this risk is the performance of preoperative, transesophageal echocardiography. Figure 1. 1. Elderly patients being considered for CABG have a higher average risk for mortality and morbidity in a direct relation to age, LV function, extent of coronary disease, and comorbid conditions and whether the procedure is urgent, emergent, or a reoperation. Observational studies showing a poorer survival effect of PTCA in patients with more advanced disease suggest that there may be a significant cost gradient for PTCA as the extent of disease increases, which is not apparent for coronary bypass surgery. Lipid-lowering therapy had not yet become standard, aspirin was not widely used, and β-blockers were used in just half of the patients. Patients with untreated, bilateral, high-grade stenoses and/or occlusions have a 20% chance of stroke. If you're overweight or obese, you can reduce your risk of further heart problems by trying to reach a healthy weight. Several of the other randomized trials, albeit with smaller numbers of patients, failed to show this trend. If pulmonary venous congestion or pleural effusions are identified, diuresis often improves lung performance. Recent guideline statements have recommended BP target ranges of <140/852 or <140/9024 based on several trials that identified these goals to be safe and beneficial for patients with a history of hypertension, diabetes, and cardiovascular risk factors. Ask for reprint No. Detection of an acute LV mural thrombus may call for long-term anticoagulation and reevaluation by echocardiography to ensure resolution or organization of the thrombus before coronary bypass surgery. 1999;34:1275) for detailed information concerning the trials listed here in column 1. use post CABG were available on approximately 1,580 subjects and 953 of those had angiography at 1 year. The etiology of these persistent effusions remains unknown. CI indicates confidence interval; CABG, coronary artery bypass graft; LAD, left anterior descending coronary artery; and LV, left ventricular. Predictors of important carotid stenosis include advanced age, female sex, known peripheral vascular disease, previous transient ischemic attack or stroke, a history of smoking, and left main coronary artery disease. Aggressive treatment of hypercholesterolemia reduces progression of atherosclerotic vein graft disease in patients after bypass surgery. Coronary heart disease is the leading cause of death among adult diabetics and accounts for 3 times as many deaths among diabetics as among nondiabetics. Finally, medical therapy was not optimized in the trials. 1. A single reprint of the executive summary and recommendations is available by calling 800-242-8721 (US only) or writing the American Heart Association, Public Information, 7272 Greenville Ave, Dallas, TX 75231-4596. Dallas, TX 75231 Although patients on chronic dialysis are at higher risk when undergoing coronary angioplasty or bypass, they are at even higher risk with conservative medical management. Table 7 summarizes survival data from the New York State registry with respect to various cohorts of patients undergoing angioplasty or bypass surgery. Table 1 shows a method by which key patient variables can be used to predict an individual patient’s operative risk of death, stroke, or mediastinitis. Risk factors include advanced age, chronic obstructive pulmonary disease, proximal right coronary disease, prolonged operation, atrial ischemia, and withdrawal of β-blockers. Clopidogrel offers the potential for fewer side effects compared with ticlopidine as an alternative in aspirin-allergic patients. The average stay for a patient post CABG is 1-5 days. 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.1,2 Beta-blockers have particular benefits for patients with a history of previous myocardial infarction, heart failure, or left ventricular dysfunction.1,2 In a recent observational study evaluating the impact of beta-blocker adherence, Zhang et al. 3. 1999;34:1276). 1993;106:664–670. Sorted by Relevance . As such, all CABG patients are candidates for long-term aspirin therapy.1 Aspirin is safe for use when administered prior to surgery,7 and a recent meta-analysis reported that preoperative aspirin significantly reduces the risk of vein graft occlusion.8 In the postoperative period, initiating aspirin therapy within 6 hours after CABG helps improve graft patency, prevents adverse cardiovascular events, and improves long-term survival.1,2, Nevertheless, even with aspirin-mediated platelet inhibition, saphenous vein graft disease continues to be a clinical challenge in the current era. This is particularly true for patients with obesity and diabetes and perhaps for those requiring prolonged ventilatory support. Therefore, several investigators have evaluated the role of other antiplatelet agents following surgery, including clopidogrel, to prevent graft occlusion and slow the progression of native CAD.9 Substantial benefits have been demonstrated with the combination of clopidogrel and aspirin in CAD trials. Previous research showed that some of this evidence was not rapidly adopted into practice by cardiothoracic physiotherapists; however, there has been no recent evaluation of the uptake of evidence. These include slowing the heart with β-blockers and calcium channel blockers and use of a mechanical stabilizing device to isolate and stabilize the target vessel. Thus, hormone replacement therapy should be considered in postmenopausal women after bypass when, in the physician’s judgment, the potential coronary benefit is not offset by an increased risk of uterine or breast cancer. Contrariwise, patients with 1-vessel disease not involving the proximal LAD had improved survival with PTCA. Cephalosporins are currently the agents of choice. Ask for reprint No. Patients with advanced chronic obstructive pulmonary disease are at particular risk for postoperative arrhythmias that may be fatal. Thus, the issue is not necessarily sex itself but the comorbid conditions that are particularly associated with the later age at which women present for coronary surgery. The study reports 16 preoperative variables, though four had the strongest associations to the need for transfusion in CABG patients: Smaller body size (especially body surface area less than 1.8 square meters) Emergency surgery. When citing this document, the American College of Cardiology and the American Heart Association request that the following citation format be used: Eagle KA, Guyton RA, Davidoff R, Ewy GA, Fonger J, Gardner TJ, Gott JP, Herrmann HC, Marlow RA, Nugent W, O’Connor GT, Orszulak TA, Rieselbach RE, Winters WL, Yusuf S. ACC/AHA guidelines for coronary artery bypass graft surgery: executive summary and recommendations: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (Committee to Revise the 1991 Guidelines for Coronary Artery Bypass Graft Surgery). Additional maneuvers to reduce type 2 neurological injury include the maintenance of steady, cerebral blood flow during cardiopulmonary bypass, avoidance of cerebral hyperthermia during and after cardiopulmonary bypass, meticulous control of perioperative hyperglycemia, and avoidance and limitation of postoperative cerebral edema. reported that the addition of clopidogrel to aspirin lowered the risk of vein graft occlusion by 41% (p = 0.02), but at the cost of significantly more major bleeding events, compared with aspirin alone.10 Importantly, this benefit for dual antiplatelet therapy appeared to be applicable only to patients undergoing off-pump CABG.10 For the majority of patients who undergo on-pump surgery in the current era, aspirin alone is currently recommended.2-3, Given the limited benefits noted with postoperative clopidogrel, several trials have been initiated to evaluate ticagrelor and prasugrel after CABG. Estimation of a patient’s risk for postoperative stroke can be calculated from Table 1. Although this risk is not necessarily higher than that with medical therapy, it has led to the argument to consider angioplasty or to delay CABG in such patients if medical stabilization can be easily accomplished. In most cases, recovery after CABG is such that, the patient is able to sit in a chair one day after the procedure, walk after 3-4 days, climb stairs after a week and get back to normal activities in 2 weeks. An important predictor of this complication is the surgeon’s identification of a severely atherosclerotic, ascending aorta before or during the bypass operation. ... A high level of blood sugar during surgery can lead to post-operative infections and poor heart function. Elements important to secondary prevention after CABG include antiplatelet and lipid-lowering medications and the aggressive management of hypertension. Ongoing ischemia not responsive to maximal nonsurgical therapy. Digoxin and calcium channel blockers have no consistent benefit for preventing atrial fibrillation after CABG, although they are frequently used to control its rate after it does occur. Therefore, initiating secondary prevention in the perioperative period is essential to optimize graft patency and allow patients to achieve the highest level of physical health and quality of life following CABG. Patients with severe LV dysfunction have increased perioperative and long-term mortality compared with patients with normal LV function. When surgery of both carotid and coronary disease is planned, the most common approach is to perform the operation in a staged manner, in which the patient first has carotid surgery followed by coronary bypass in 1 to 5 days. The American College of Cardiology/American Heart Association (ACC/AHA) Task Force on Practice Guidelines was formed to make recommendations regarding the appropriate use of diagnostic tests and therapies for patients with known or suspected cardiovascular disease. Class I indications for CABG from the American College of Cardiology (ACC) and the American Heart Association (AHA) are as follows [1, 2] : 1. Intraoperative assessment with epiaortic imaging is superior to both methods. Table 5. The administration of the serine protease inhibitor aprotinin may attenuate complement activation and cytokine release during extracorporeal circulation. The 15-year cumulative survival for left main coronary artery disease patients having CABG surgery was 44% versus 31% for medical patients. Cardiac rehabilitation has a highly beneficial effect in patients who are moderately or severely depressed. P values for heterogeneity across studies were 0.49, 0.84, and 0.95 at 5, 7, and 10 years, respectively. Tables 3, 4, and 5 and the Figure provide estimates of long-term outcomes among patients randomized in the trials. In addition, because the studies were done in the late 1970s and early 1980s, only 1 of the trials used arterial grafts, and even that trial had no arterial grafts in 86% of patients. An individual patient’s risk of postoperative mediastinitis can be estimated from Table 1. Currently, the risks are likely very low and have been estimated to be 1/493 000 for human immunodeficiency virus, 1/641 000 for human T-cell lymphotrophic virus, 1/103 000 for hepatitis C virus, and 1/63 000 for hepatitis B virus. 6. Administration of corticosteroids before cardiopulmonary bypass may reduce complement activation and release of proinflammatory cytokines. Currently, routine use of the left internal mammary artery for LAD grafting with supplemental saphenous vein grafts to other coronary lesions is generally accepted as a standard grafting method. This observation strengthens the argument for careful outcome tracking and supports the monitoring of institutions or individuals who annually perform <100 cases. 3. With cardiopulmonary bypass and cardioplegic arrest, CABG can be performed with video assistance on a still and decompressed heart through several small ports. Door een extra bloedvat aan te leggen en een aansluiting te maken op het vernauwde bloedvat komt er weer genoeg bloed en zuurstof in de hartspier. Compared with conventional CABG, median sternotomy is avoided. Another area of evolving technology is the use of arterial and alternate conduits. Leukodepletion of transfused blood also reduces this effect. Two studies which titrated prophylactic BB dosages to heart rates of 60–90 per minute, did not find any correlation between higher dosages and prevention of post‐CABG AF. 1999;33:67. Intraoperative surgical manipulation or spontaneous resumption of sinus rhythm during the early postoperative period may lead to embolism of a left atrial clot. Disabling angina despite maximal noninvasive therapy. Statins have been shown to reduce the progression of native artery atherosclerosis, slow the process of vein graft disease, and reduce adverse cardiovascular events following surgical revascularization.1,2,16 For many years, statins were administered after CABG to reduce low-density lipoprotein levels to <100 mg/dL. Several studies have suggested that blood cardioplegia (compared with crystalloid) may offer a greater margin of safety during CABG performed on patients with acute coronary occlusion, failed angioplasty, urgent revascularization for unstable angina, and/or chronically impaired LV function. Predictors of type 2 deficits include a history of excess alcohol consumption; dysrhythmias, including atrial fibrillation; hypertension; prior bypass surgery; peripheral vascular disease; and congestive heart failure. While several studies have suggested improvement in angina severity with transmyocardial laser revascularization, the mechanism by which angina improves and the overall benefit on long-term angina and/or survival await further clarification. Thus, CABG should not be delayed in or denied to women who have appropriate indications. Pharmacological Strategies for Prevention of Atrial Fibrillation (AF) After Coronary Artery Bypass Graft Surgery. Its incidence of severe leukopenia is rare. Data regarding the benefit of cholesterol lowering after bypass surgery are most supported by studies that have used HMG CoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase inhibitors, particularly targeting LDL levels to <100 mg/dL. Transesophageal echocardiography is useful for aortic arch examination, but examination of the ascending aorta may be limited by the intervening trachea. Studies suggest that mortality after CABG is higher when carried out in institutions that annually perform fewer than a minimum number of cases. 5. However, the risk of bypass surgery in patients with unstable or postinfarction angina or early after non–Q wave infarction and during acute MI is increased severalfold compared with patients with stable angina. published a clinical trial whereby 500 patients were randomized to ticagrelor plus aspirin, ticagrelor alone, or aspirin alone following surgery.14 One year after CABG, the authors reported that the combination of ticagrelor with aspirin significantly improved 1-year vein graft patency compared with aspirin alone (11.3% vs. 23.5%, ticagrelor plus aspirin versus aspirin alone, p < 0.001). For patients with aortic walls ≤3 mm thick, standard treatment is used. Left main equivalent disease (≥70% stenosis in both the proximal left anterior descending [LAD] and proximal left circumflex arteries) appeared to behave similarly to true left main coronary artery disease. If deep sternal wound infection does occur, aggressive surgical debridement and early vascularized muscle flap coverage are the most effective methods for treatment, along with long-term systemic antibiotics. Thus, stroke risk is particularly increased in patients beyond 75 to 80 years of age. Efficacy is dependent on adequate drug tissue levels before microbial exposure. 3. Half of the patients approached were ineligible owing to left main coronary artery disease, insufficient symptoms, or other reasons. 1993;21:1124–1131. A coronary artery bypass graft (CABG) isn't a cure for heart disease, ... Read more about the physical activity guidelines for adults (19 to 64). Thus, internal mammary artery use should be encouraged in the elderly, emergent, or acutely ischemic patient and other patient groups. A higher proportion of rehabilitated patients are working at 3 years after CABG. 2. Important components of “fast-track” care are careful patient selection, patient and family education, early extubation, prophylactic antiarrhythmic therapy, dietary considerations, early ambulation, early outpatient telephone follow-up, and careful coordination with other physicians and healthcare providers. The guidelines also incorporate new findings on post-CABG in-hospital management and subsequent medical therapy and challenge the common misconception that off-pump CABG … (If angina is not typical, then objective evidence of ischemia should be obtained.). The trials defined significant left main coronary artery stenosis as a >50% reduction in lumen diameter. Prophylactic Antimicrobials for Coronary Artery Bypass Graft Surgery. Nevertheless, lower BP goals will likely be recommended in upcoming guideline statements based on the impressive results of this trial. By 10 years, 37% to 50% of medically assigned patients had crossed over to surgery. Other trials are exploring the impact of combining aspirin with ticagrelor to reduce postoperative graft occlusion rates (ClinicalTrials.gov Identifier: NCT02352402) and ticagrelor's role in reducing postoperative clinical events (ClinicalTrials.gov Identifier: NCT01755520). Thus, some institutions and practitioners maintain excellent outcomes despite relatively low volumes. As a consequence of improved patency, patients receiving an LAD graft with an internal mammary artery have improved survival compared with patients receiving only vein grafts. Lose weight. In patients with CAD, aspirin reduces the risk of stroke, myocardial infarction, and vascular death. 71-0174. In patients for whom mammary artery, radial artery, and standard vein conduits are unavailable, the in situ right gastroepiploic artery, the inferior epigastric free artery graft, and either lesser saphenous or upper-extremity vein conduits have been used. More than 85% of patients develop pleuraleffusions after coronary artery bypass grafting (CABG). ... in the CABG patient with diabetes was presented by Lazar and coworkers [11] using a modified glucose- Future studies from this group will help determine whether early high-intensity statin therapy has an impact on the development of vein graft disease in the years that follow surgery.21,22, Figure 1: Incidence of Vein Graft Stenosis or Occlusion at 1 Year Among Patients Randomized to Atorvastatin 10 mg or Atorvastatin 80 mg Early After CABG. An aggressive approach to the management of patients with severely diseased ascending aortas identified by intraoperative echocardiographic imaging reduces the risk of postoperative stroke. The American College of Cardiology/American Heart Association (ACC/AHA) Task Force on Practice Guidelines was formed to make recommendations regarding the appropriate use of diagnostic tests and therapies for patients with known or suspected cardiovascular disease. However, studies suggest that the beneficial effects of myocardial revascularization in patients with ischemic heart disease and severe LV dysfunction are sizeable when compared with medically treated patients of similar status in terms of symptom relief, exercise tolerance, and survival. The initial cost and length of stay were lower for angioplasty than for CABG. After adjustment for various covariates, bypass surgery in the New York State registry experience was associated with longer survival in patients with severe proximal LAD stenosis and/or 3-vessel disease. The referral physician needs to provide clear, written reports of the findings and recommendations to the primary care physician, including discharge medications and dosages along with long-term goals. A variety of measures have been tried to reduce the systemic consequences of cardiopulmonary bypass, which elicits a diffuse inflammatory response that may cause transient or prolonged multisystem organ dysfunction. This site uses cookies. organization. Intracoronary stents have been used to treat saphenous vein graft stenosis in patients with previous CABG. Primary reperfusion in the early hours (≤6 to 12 hours) of an evolving ST-segment elevation MI. The BARI trial suggested that diabetics with multivessel coronary disease derived advantage from bypass surgery compared with angioplasty. LAD indicates left anterior descending coronary artery; CABG, coronary artery bypass graft; and PTCA, percutaneous transluminal coronary angioplasty. However, in the cardiac surgery literature, the results have been mixed. When possible, the primary care physician should follow up the patient during the perioperative course. Particular predictors of type 1 deficits include proximal aortic atherosclerosis as defined by the surgeon at operation, history of prior neurological disease, use of the intra-aortic balloon pump, diabetes, hypertension, unstable angina, and increased age. However, chronic, persistent post-CABG effusions have been reported. Diabetics who are candidates for renal transplantation have a particularly high incidence of coronary artery disease, even in the absence of symptoms or signs. Class IIa: Weight of evidence/opinion is in favor of usefulness/efficacy. The use of transmyocardial laser revascularization has generally been performed surgically for patients with severe angina refractory to medical therapy and who are not suitable candidates for standard surgical revascularization, PTCA, or heart transplant. Hemodynamic compromise in patients with impairment of coagulation system and without previous sternotomy. For healthcare professionals, administering secondary preventative therapies is a fundamental responsibility following CABG. Intraoperative palpation underestimates the high-risk aorta. Although the relative benefit was similar, the absolute benefit was greater because of the high-risk profile of these patients. 142, Issue Suppl_4, November 17, 2020: Vol. The presence of clinical and subclinical peripheral vascular disease is a strong predictor of increased hospital and long-term mortality rates in patients undergoing CABG. Miguel Sousa-Uva*, Stuart J Head, Milan Milojevic, Jean-Philippe Collet, Giovanni Landoni, Manuel Castella, Joel Dunning, Tómas Gudbjartsson, Nick J Linker, Elena Sandoval, Matthias Thielmann, Anders Jeppsson, Ulf Landmesser*, 2017 EACTS Guidelines on perioperative medication in adult cardiac surgery, European Journal of Cardio-Thoracic Surgery, Volume 53, Issue 1, January … Even among a large group of patients with multivessel disease suitable for enrollment, only half were actually randomized. There is no universally applicable myocardial protection technique. 2. Off-bypass coronary surgery is performed on a beating heart after reduction of cardiac motion with a variety of pharmacological and mechanical devices. Class II: Conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness or efficacy of a procedure. For patients without exclusions, such as low hemoglobin values, heart failure, unstable angina, left main coronary artery disease, or advanced anginal symptoms, self-donation of 1 to 3 units of red blood cells over 30 days before operation reduces the need for homologous transfusion during or after operation. Microembolization is thought to be a major contributor to the postoperative cerebral dysfunction after CABG. Recent guideline statements have recommended BP target ranges of <140/85 2 or <140/90 24 based on several trials that identified these goals to be safe and beneficial for patients with a history of hypertension, diabetes, and cardiovascular risk factors. Reversed long saphenous vein is the most commonly used conduit despite the known early thrombotic failure and low long-term patency rate. Progressive LV pump failure with coronary stenosis compromising viable myocardium outside the initial infarct area. Circulation. These data can be used to estimate 3-year survival expectations for patients with various anatomic features. The right coronary artery can be approached by using a right anterior thoracotomy. Thus, in patients with modest reductions in LV function, significant left main or 3-vessel disease, and/or unstable angina, coronary revascularization can lead to relief of coronary symptoms, improvement in overall functional status, and improved long-term survival in this select high-risk patient population. Extensive evidence exists supporting the use of statins to treat hyperlipidemia and improve long-term survival for patients with CAD, particularly for those who have had CABG. For high-risk patients with multiple or circumferential involvement or those with extensive middle ascending aortic involvement, replacement of the ascending aorta under hypothermic circulatory arrest may be indicated.
