Microembolization is thought to be a major contributor to the postoperative cerebral dysfunction after CABG. Adverse cerebral outcomes are observed in ≈6% of patients after bypass surgery and are equally divided between type 1 and type 2 deficits. Figure. Disabling angina despite maximal medical therapy, when surgery can be performed with acceptable risk. 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. Accordingly, although the clinical trials have provided important insights, their interpretation must be viewed with caution, given the evolution in all types of coronary therapies. At 5 years, two thirds of bypass patients were symptom-free compared with 38% of medically assigned patients. Outcome reporting in the form of risk-adjusted mortality rates after bypass has been effective in reducing mortality rates nationwide.

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. Risk factors include advanced age, chronic obstructive pulmonary disease, proximal right coronary disease, prolonged operation, atrial ischemia, and withdrawal of β-blockers. Cardiac rehabilitation reinforces pharmacological therapy and smoking cessation and should be offered to all eligible patients after CABG. 1997;39:97–101. This is particularly true for patients with obesity and diabetes and perhaps for those requiring prolonged ventilatory support. 1. Despite the increasing safety of homologous blood transfusion, concerns surrounding viral transmission during transfusion remain. Two randomized controlled trials raised doubts regarding the benefits of initiating high-dose statin therapy in the perioperative period. Vascular access for cardiopulmonary bypass is achieved via the femoral artery and vein. Among all patients, the extension survival of CABG surgical patients compared with medically treated patients was 4.3 months at 10 years of follow-up. Over 50% left main coronary artery stenosis 2. 1. 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. Routine use of aprotinin is limited by its high cost. However, the authors noted a trend toward fewer patients developing vein graft disease (either occlusion or stenosis) in the atorvastatin 80 mg group (29.2% vs. 19.2%, atorvastatin 10 mg vs. atorvastatin 80 mg, p = 0.18). Three-vessel disease with proximal LAD stenosis in patients with poor left ventricular (LV) function 5. Intracoronary stents have been used to treat saphenous vein graft stenosis in patients with previous CABG. The benefits include better physical mobility and perceived health. Subgroup Results at 5 Years. Additionally, 3 to 6 months of anticoagulation therapy is appropriate for patients with persistent, anterior wall–motion abnormalities after coronary bypass surgery. To make photocopies for personal or educational use, call the Copyright Clearance Center, 978-750-8400. Currently, “less-invasive” CABG surgery can be divided into 3 categories: (1) off-bypass CABG performed through a median sternotomy with a smaller skin incision, (2) minimally invasive direct CABG (MID-CAB) performed through a left anterior thoracotomy without cardiopulmonary bypass, and (3) port-access CABG with femoral-to-femoral cardiopulmonary bypass and cardioplegic arrest with limited incision. 1. Class IIa: Weight of evidence/opinion is in favor of usefulness/efficacy. Cephalosporins are currently the agents of choice. What are the risk factors for complications? Administration of corticosteroids before cardiopulmonary bypass may reduce complement activation and release of proinflammatory cytokines. Nowadays, CABG is performed using a minimally invasive technique, and estimated time frame for recovery is less than 2 weeks. Lancet. Currently, the routine preoperative or early postoperative administration of β-blockers is considered standard therapy to reduce the risk of atrial fibrillation after CABG. Nevertheless, reasonable 5- and 10-year survival rates after reoperation for coronary disease can be achieved, and the operation is appropriate if the severity of symptoms and anticipated benefit justify the immediate risk. … Registry studies have shown a reduction in late MI among highest-risk patients, such as those with 3-vessel disease, and/or those with severe angina. 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. Coronary artery bypass graft surgery (CABG) is the most complete and durable treatment of ischemic heart disease and has been an established therapy for nearly 50 years. This does not allow a lot of time in the inpatient setting for formal exercise training to occur. 142, Issue Suppl_3, October 20, 2020: Vol. However, potential morbidity of the port-access operation includes multiple wounds at port sites, the limited thoracotomy, and the groin dissection for femoral-femoral bypass. 1. Inability to revascularize owing to target anatomy or no-reflow state. If you're overweight or obese, you can reduce your risk of further heart problems by trying to reach a healthy weight. Virtually every study of patients receiving β-blockers prophylactically has shown benefit in lowering the frequency of atrial fibrillation. Transesophageal echocardiography is useful for aortic arch examination, but examination of the ascending aorta may be limited by the intervening trachea. Although it is widely appreciated that use of the internal mammary artery leads to improved long-term survival after coronary bypass surgery, it has also been documented that use of the internal mammary artery influences operative mortality itself. 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. Postoperative neurological deficits have been divided into 2 types: type 1, associated with major, focal neurological deficits, stupor, or coma; and type 2, in which deterioration in intellectual function is evident. The benefit of CABG compared with medical therapy in various clinical subsets is presented below. Ticlopidine offers no advantage over aspirin but is an alternative in truly aspirin-allergic patients. 1998;19:234–239. 2. These early results are consistent with the known superior graft patency of arterial conduits compared with vein grafts. Among patients with a preoperative creatinine level >2.5 mg/dL, 40% to 50% require hemodialysis. Proximal LAD disease with 1- or 2-vessel disease.‡3. The end point of the trials was primarily survival. Preoperative antibiotic administration reduces the risk of postoperative infection 5-fold. Aggressive, perioperative glucose control in diabetics through the use of continuous, intravenous insulin infusion reduces perioperative hyperglycemia and its associated infection risk. By 10 years, however, these differences were no longer significant. The extent of revascularization achieved by bypass surgery was generally higher than with angioplasty.
