TY - JOUR. T1 - Network meta-analysis of antiplatelet therapy following coronary artery bypass grafting (CABG). T2 - none versus one versus two antiplatelet agents. AU - Chakos, Adam. AU - Jbara, Dean. AU - Singh, Kamal. AU - Yan, Tristan D.. AU - Tian, David H.. PY - 2018/9/1. Y1 - 2018/9/1. N2 - Background: Numerous agents have been trialed following coronary artery bypass grafting (CABG) to maintain long-term graft patency. While clear evidence exists for the use of aspirin in maintaining graft patency, the role of dual-antiplatelet therapy in CABG patients is not as well established. This network meta-analysis aimed to compare the short-term post-CABG graft patency outcomes for patients with none, one or two antiplatelet agents. Methods: Electronic databases were queried for randomized controlled trials comparing CABG graft patency rates at three months and beyond using various antiplatelet agents or placebo. Drug and graft patency data were compared using a mixed treatment comparison under ...
Background: The SHOCK Trial demonstrated that early revascularization (ERV) provided a survival advantage compared with initial medical stabilization in patients with acute myocardial infarction (MI). The ideal revascularization strategy for patients with cardiogenic shock in the setting of left main coronary artery (LMCA) disease is unknown.. Methods: We compared 30-day survival rates associated with coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in this clinical setting. A multiple Cox regression model with left truncation was used to identify risk factors for 30-day mortality and attempt to correct for the bias that would be attributable to the differential time to revascularization.. Results: The SHOCK Trial (n=144) and Registry (=33) included 177 patients with significant (,50%) LMCA disease who underwent revascularization (CABG or PCI). Although the trial protocol recommended CABG for patients with LMCA involvement, the revascularization strategy (92 ...
An aneurysm is defined as dilatation of the artery greater than 50% in diameter. Aneurysms are categorized as fusiform or saccular. The saccular aneurysms of the ascending aorta are rarely seen and are usually life-threatening. Excessive use of biologicglue, graft infection, mediastinitis, aortic dissection, atherosclerosis, hypertension, degeneration of a penetrating atherosclerotic ulcer, poorsurgical technique, trauma, fungal infections and previous aortic surgery (presumably due to the cannulation site) are the etiologic risk factors for the development of a false or true aneurysm of the ascending aorta [1]. There are a few reports for saccular aneurysm of the ascending aorta which are following coronary artery bypass grafting surgery. The wall stressis greater in saccular aneurysms rather than fusiform aneurysms. The disruption of the vesse lwall at the cannulation site oral long the aortic suture lines lead to saccular aneurysm.. Theaortic false aneurysm may surrounded and restricted by ...
Midazolam and propofol were compared in an open randomized study for postoperative sedation during 12 h of mechanical ventilation in 40 patients following coronary artery bypass grafting. After an intravenous loading dose of midazolam (50 micrograms.kg-1) or propofol (500 micrograms.kg-1), a titrated continuous infusion was administered of midazolam (mean dose 38.1 micrograms.kg-1.h-1 (SEM 2.6)) or propofol (mean dose 909 micrograms.kg-1.h-1 (SEM 100)) together with a narcotic analgesic infusion. During mechanical ventilation midazolam and propofol produced a similar quality of sedation, but recovery (midazolam 66 min (SEM 16); propofol 24 min (SEM 7)) and weaning from the ventilator (midazolam 243 min (SEM 44); propofol 154 min (SEM 33)) where faster with propofol. In the 2 groups administration of an intravenous loading dose caused a significant decrease in mean arterial pressure but hemodynamic tolerance during maintenance infusion was good ...

Researchers said that in comparison to coronary artery bypass patients who have normal weight, patients with extreme obesity were thrice more vulnerable to develop an infection post-bypass surgery. Through the coronary artery bypass surgery, blood flow is redirected to the heart surrounding clogged heart arteries.. The studys senior author, Mary Forhan, Ph.D., assistant professor at the University of Alberta in Edmonton, Canada, said, "Based on the results of this study it appears that addressing infection risk might be an effective strategy to decrease the length-of-stay for patients with obesity who undergo coronary artery bypass surgery".. The study used a Canadian database of heart patients, and analyzed how a racially and ethnically varied group of 7,560 patients fared following a bypass surgery in Edmonton in the years April 2003 to March 2014.. The division of the patients was done as per their body mass index into five different groups, including normal weight with BMI 18.5-24.9; ...

N2 - Early or prophylactic inotropic drug administration is occasionally required to facilitate separation from cardiopulmonary bypass (CPB) in cardiac surgery. However, it is not without untoward effects and should be conducted on the basis of rational criteria. The purpose of our study was to clarify variables associated with the requirement for inotropic support during separation from CPB and to testify whether pre-CPB left ventricular (LV) function, as evaluated by transesophageal echocardiography (TEE), is one of the significant variables. Clinical profile data and TEE findings were retrospectively analyzed for 91 patients who had received elective primary isolated coronary artery bypass grafting (CABG) surgery. Post-CPB inotropic drug administration ...
OBJECTIVES We sought to ascertain the utility of adenosine thallium-201 tomography for assessing graft stenoses late after coronary artery bypass graft surgery. BACKGROUND Although pharmacologic perfusion imaging has been increasingly used in the assessment of patients with coronary artery disease, the value of this stress modality for detecting coronary artery bypass graft stenosis late after surgery is unknown. METHODS We studied 109 patients who underwent both adenosine thallium-201 tomography and coronary angiography at 6.7 +/- 4.8 (mean +/- SD) years after coronary artery bypass graft surgery. Adenosine thallium-201 tomography was assessed quantitatively by computer-generated polar maps of the myocardial thallium-201 activity. RESULTS On coronary angiography, significant graft stenoses were present in 68 patients, 65 of whom had a corresponding perfusion defect as shown by thallium-201 tomography (sensitivity 96%). Significant stenoses were present in 107 (37.8%) of 283 grafts. The overall

Atrial fibrillation (AF) is a common complication after coronary artery bypass grafting. Atrial remodeling has been observed in AF and has been associated with the development of this arrhythmia. Because 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins) have been demonstrated to modify remodeling, we hypothesized a protective role of statins against postoperative AF. We also hypothesized that extracellular matrix turnover and brain natriuretic peptide (BNP) might be related to such atrial remodeling. We studied 234 consecutive patients who underwent coronary artery bypass grafting (173 men; 65 +/- 9 years of age) in whom the occurrence of postoperative AF was monitored. In a subgroup of 66 patients, we measured plasma levels of matrix metalloproteinase-1 (MMP-1), its inhibitor, tissue inhibitor matrix metalloproteinase-1 (TIMP-1; as indexes of extracellular matrix remodeling), and N-terminus pro-BNP (related to left ventricular function) at baseline and at 24 hours after surgery. Of 234 ...
New research shows that a minimally invasive approach used during coronary artery bypass grafting surgery is safe and effective, despite previous studies that linked endoscopic vein harvesting to a higher mortality rate. The research, published in the August 1, 2012 edition of The Journal of the American Medical Association, was an observational study of more than 235,000 patients included in The Society of Thoracic Surgeons National Database who underwent CABG surgery at 934 participating surgical centers. Investigators compared the three-year outcomes of patients undergoing EVH to the outcomes of patients undergoing the more invasive open vein harvesting (OVH) procedure and found no difference in mortality rates. "This study should alleviate concerns of patients and surgeons raised by past studies, and confirms the superiority of the EVH technique in terms of infection and wound complication rates that makes the minimally invasive approach the preferred method," said senior author Peter K. ...
OBJECTIVES The mechanisms of postoperative cognitive dysfunction in patients with diabetes after coronary artery bypass grafting are not fully understood. We sought to determine which type 2 diabetes-related factors contributed to postoperative cognitive dysfunction at 7 days and 6 months after coronary artery bypass grafting. METHODS One hundred eighty patients with type 2 diabetes who were scheduled for elective coronary artery bypass grafting were studied. As a control group, 100 patients without diabetes mellitus matched for age, sex, and educational level were examined. Hemodynamic parameters (arterial and jugular venous blood gas values) were measured during cardiopulmonary bypass. All patients underwent a battery of neurologic and neuropsychologic tests the day before surgery, 7 days after surgery, and 6 months after surgery. RESULTS Age (odds ratio 1.5, 95% confidence interval 1.3-1.8, P = .03), presence of hypertension (odds ratio 1.8, 95% confidence interval 1.3-2.0, P = .01), jugular

Between 2001 and 2008, the annual rate of coronary artery bypass graft surgeries performed in the United States decreased by more than 30 percent, but rates of percutaneous coronary interventions (PCI; procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries) did not change significantly, according to a study in the May 4 issue of JAMA.. "Coronary revascularization, comprising coronary artery bypass graft (CABG) surgery and PCI, is among the most common major medical procedures provided by the U.S. health care system, with more than 1 million procedures performed annually," according to background information in the article. Several innovations in coronary revascularization, such as drug-eluting stents (DES) and minimally invasive CABG surgery have been adopted widely in the past decade, with the promise of improved clinical outcomes compared with older revascularization technologies and techniques. "During this period of technological innovation, new ...
Main Research Question(s):. What is the effect of continuing aspirin until the time of coronary artery bypass graft surgery and of adding clopidogrel to aspirin after coronary artery bypass graft surgery for preventing blockage of coronary grafts, heart attack, stroke, and death? To reliably answer this question requires a large randomised trial. Before applying for a major grant from the Canadian Institute for Health Research to do the large study we would like to perform a small pilot study of 150 patients to demonstrate that it is feasible to recruit patients and to use a new test called CT angiography to determine whether the bypass grafts are still working or have become blocked.. (ii) Why is this research important? Coronary artery bypass surgery has made a very important contribution to improving the health and survival of patients with advanced coronary artery disease but still has many problems. One in 10 patients experiences a heart attack at the time of surgery, 1 in 20 experiences ...

The generalizability of a prediction model from North America for incident nosocomial pneumonia following coronary artery bypass graft surgery was assessed for 23247 patients on the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) registry. The performance of the North American model was evaluated using measures of calibration and discrimination. The model had reasonable discrimination (area under the receiver-operating characteristic curve, AUC=0·69), but unsatisfactory calibration (Hosmer-Lemeshow test, P,0·001) in the ANZSCTS patients. An update of the model coefficients yielded a model with AUC=0·71 and good calibration (P=0·46). © 2013 Cambridge University Press.. ...

Interventions: ... read more None. Measurements and Main Results: IOH-CPB was defined as blood pressure below several absolute and relative mean arterial pressure (MAP) thresholds and as the area under the curve for absolute MAP thresholds. AKI was defined as an absolute increase in serum creatinine of≥26 μmol/L within 48 hours or an increase to 150% or more within 7 days of surgery. Poisson regression with robust standard errors both before and after adjustment for confounders was used. Of the 1,891 patients included, 386 (20%) developed AKI. In univariable analysis, all IOH-CPB thresholds defined as a MAP of 50 ...
To evaluate the relative long-term improvement in coronary artery hemodynamics after revascularization by coronary artery bypass graft surgery (CABG) or percutaneous transluminal coronary angioplasty (PTCA), regional coronary flow reserve (CFR) was measured, by digital computer analysis of 35 mm cine film, in 50 men undergoing cardiac catheterization. CFR (mean +/- SEM) in 12 atherosclerotic arteries before revascularization was 1.02 +/- 0.05. Mean CFR in 29 normal arteries of men with normal coronary arteriograms was significantly higher (2.59 +/- 0.11) than that in 16 atherosclerotic arteries of patients revascularized by CABG (2.02 +/- 0.17, p less than .01) or in 14 atherosclerotic arteries of those revascularized by PTCA (1.97 +/- 0.12, p less than .01). No difference in CFR between the CABG and PTCA groups was found and variables known to influence CFR were similar between groups. Equivalent and significant long-term improvement in coronary artery hemodynamics is provided by CABG or PTCA. ...
We read with great interest the study by Hongo et al. (1)entitled "The Effect of Clopidogrel in Combination With Aspirin When Given Before Coronary Artery Bypass Grafting." This very interesting study highlights an emerging problem for patients having routine coronary artery bypass graft surgery (CABG) after percutaneous intervention, as described in their report, but also for patients with an acute coronary syndrome who require urgent "in-house surgery" because these patients are invariably on both clopidogrel and aspirin therapy.. In their study, the investigators showed that continued clopidogrel therapy within seven days of elective CABG results in increased blood loss, increased use of blood products, and increased re-exploration rates. Unfortunately, although the study was prospective there was no blinding of the nurses or clinicians to clopidogrel and aspirin exposure.. This lack of blinding is crucial to determine whether the main outcomes of the study are credible. The investigators ...
There are limitations to the conclusions that can be drawn from this study. Firstly, the comparisons we have made here are not an attempt to estimate either the effectiveness of coronary artery bypass surgery, or the relative balance of benefits and risks associated with early intervention for particular patients. There is clear evidence from randomised controlled trials that an initial strategy of coronary artery bypass surgery is associated, in the long term, with reduced mortality rates in patients with significant left main-stem stenosis, three vessel disease and proximal left anterior descending artery disease.2 However, it should be remembered that, on average, coronary artery bypass surgery prolongs life by only 4.26 months.2 Secondly, the six month postoperative period analysed here accentuates mortality risk associated with the procedure itself; for people who would benefit prognostically from surgery, the total risk faced is the sum of the risk while waiting plus the postoperative ...
BACKGROUND: External stents inhibit saphenous vein graft (SVG) intimal hyperplasia in animal studies. We investigated whether external stenting inhibits SVG diffuse intimal hyperplasia 1 year after coronary artery bypass graft surgery. METHODS: Thirty patients with multivessel disease undergoing coronary artery bypass graft surgery were enrolled. In addition to an internal mammary artery graft, each patient received one external stent to a single SVG randomly allocated to either the right or left coronary territories; and one or more nonstented SVG served as the control. Graft patency was confirmed at the end of surgery in all patients. The primary endpoint was SVG intimal hyperplasia (mean area) assessed by intravascular ultrasonography at 1 year. Secondary endpoints were SVG failure, ectasia (|50% initial diameter), and overall uniformity as judged by Fitzgibbon classification. RESULTS: One-year follow-up angiography was completed in 29 patients (96.6%). All internal mammary artery grafts were patent.
This 3D medical animation shows a coronary artery bypass graft (CABG) procedure used to combat coronary artery disease. Beginning with a midline sternal incision, the heart is connected to a perfusion machine which will take over the duties of the heart while the surgery takes place. Two different grafts are used to bypass the blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg. After the procedure, the heart is shocked to restart its beating. A drainage tube is left at the incision site to drain away excess fluid. The animation continues to show two other types of approaches to a coronary artery bypass graft, off-pump bypass surgery and minimally invasive bypass surgery.
By Dr. Nikhil Pendse, Cardiology. CABG or also known as Coronary Artery Bypass Grafting is one of the most common types of open heart surgery in many parts of the world. There are different names in which CABG can be described as well as - Bypass surgery or Heart Bypass surgery.. CABG can be used to treat serious and very important heart diseases. However, not everyone who has a CHD needs to be treated with CABG.. In CABG or angioplasty, a small tube or mesh which is called the stent is placed in an artery so that it remains open and the surgery can be efficiently carried out. CABG is a brilliant option when you have different kinds of blockages in the large coronary arteries. If your heart pumping action has decreased then CABG is also effective. Blockages in the cardiovascular chambers can also be treated with the help of CABG.. Benefits of Coronary Artery Bypass Grafting:. Here are some important benefits which can be obtained when you undergo CABG:. ● Improves your lifestyle and physical ...

Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") surgery, and colloquially heart bypass or bypass surgery, is a surgical procedure to restore normal blood flow to an obstructed coronary artery. A normal coronary artery transports blood to and from the heart muscle itself, not through the main circulatory system. There are two main approaches. In one, the left internal thoracic artery (internal mammary artery) is diverted to the left anterior descending branch of the left coronary artery. In the other, a great saphenous vein is removed from a leg; one end is attached to the aorta or one of its major branches, and the other end is attached to the obstructed artery immediately after the obstruction to restore blood flow. CABG is performed to relieve angina unsatisfactorily controlled by maximum tolerated anti-ischemic medication, prevent or relieve left ventricular dysfunction, and/or reduce the risk of death. CABG does not prevent myocardial ...
Objective: To evaluate our experience with the radial artery in coronary artery bypass grafting. Methods: We studied 156 consecutive patients who had a single radial artery as coronary grafts. All patients underwent a modified Aliens test. Radial artery were harvested by no touch technique. Results: An average of 3.3 grafts perpatient were performed. Operative mortality occurred in 1 (0.6%) patients, no stroke, deep sternal infection and fingertip ischemia. Reoperation for hemorrhage in 2 (1.3%), and myocardial ischemia in 1 (0.6%). Conclusion: Good early clinical results can be achieved by using the radial artery in coronary artery bypass grafting.
OBJECTIVES: There is still little evidence to boldport routine dual antiplatelet therapy (DAPT) with P2Y12 antagonists following coronary artery bypass grafting (CABG). The Arterial Revascularization Trial (ART) was designed to compare 10-year survival after bilateral versus single internal thoracic artery grafting. We aimed to get insights into the effect of DAPT (with clopidogrel) following CABG on 1-year outcomes by performing a post hoc ART analysis. METHODS: Among patients enrolled in the ART (n = 3102), 609 (21%) and 2308 (79%) were discharged on DAPT or aspirin alone, respectively. The primary end-point was the incidence of major adverse cerebrovascular and cardiac events (MACCE) at 1 year including cardiac death, myocardial infarction, cerebrovascular accident and reintervention; safety end-point was bleeding requiring hospitalization. Propensity score (PS) matching was used to create comparable groups. RESULTS: Among 609 PS-matched pairs, MACCE occurred in 34 (5.6%) and 34 (5.6%) in the DAPT
Background and objective: Myocardial ischaemia and infarction are major complications immediately after coronary artery bypass grafting. They may be due to incomplete surgical revascularization, perioperative anaesthetic management or vasospasm of arterial grafts, e.g. the internal mammary artery. Infusions of nifedipine or milrinone have been advocated to prevent spasm of the mammary artery. The study compared the incidence of myocardial ischaemia after continuous infusion of either nifedipine (0.2 µg kg−1 min−1) or milrinone (0.375 µg kg−1 min−1) in patients with compromised left ventricular function scheduled for elective coronary artery bypass graft.. Methods: After Institutional Review Board approval, this double-blinded randomized clinical study enrolled 30 adult patients with compromised left ventricular function (ejection fraction ,0.4) scheduled for elective coronary artery bypass grafting after written informed consent had been obtained. Ischaemia was detected by Holter ...

Objective. To investigate oxidative stress and myocardial injury at different stages of coronary artery bypass grafting (CABG). Design. Twenty patients underwent CABG with use of cardiopulmonary bypass (CPB) and with intermittent sampling of plasma and urine. Main markers were: 8-iso-PGF(2 alpha) (oxidative stress); troponin T (myocardial injury); and 15-keto-dihydro-PGF2 alpha and hsCRP (inflammation). Results. Plasma 8-iso-PGF2 alpha increased after start of surgery, but there was no further rise during CPB or after aortic cross-clamp release and no significant myocardial arterio-venous differences. An increase in troponin T was seen early after the operation, but no relationship was established between 8-iso-PGF2 alpha and troponin T. 8-iso-PGF2 alpha levels were elevated by preoperative withdrawal of acetylsalicylic acid (ASA) but reduced by intraoperative use of heparin. 15-keto-dihydro-PGF2 alpha was elevated during operation and hsCRP following operation. Conclusions. In the present study ...

For over a decade there has been accumulating evidence that the use of more than a single arterial graft during coronary artery bypass grafting can improve clinical outcomes. However the vast majority of patients in most developed countries still only receive a single arterial conduit even in the presence of multivessel coronary artery disease. This review summarizes the current evidence for the use of a second internal mammary artery and/or radial artery graft. While in comparison to vein grafts the superior patency of internal mammary artery grafts is well established, there now exists strong and consistent evidence of the superior patency of radial arteries over the longer term. Likewise, there is a rapidly growing body of evidence that the superior patency of both these arteries in comparison to vein grafts translates into improved clinical outcomes.
