Incidence, Trends, and Predictors of Ischemic Stroke 30 Days After an Acute Myocardial Infarction Clinical Sciences
Conclusions— The incidence of ischemic stroke within 30 days of an AMI has decreased during the period 1998 to 2008. This decrease is associated with increased use of acetylsalicylic acid, P2Y12 inhibitors, statins, and percutaneous coronary intervention.

Influencing Factors for Early Acute Cerebrovascular Accidents in Patients with Stroke History following Off-pump Coronary Artery Bypass Grafting
Conclusions: This study indicated that patients with severe bilateral carotid stenosis, the left ventricular ejection fraction ≤35%, the postoperative acute myocardial infarction, postoperative atrial fibrillation and postoperative hypotension were more likely to suffer from early acute cerebrovascular accidents when they received OPCAB. Application of Enclose® II proximal anastomotic device may decrease the incidence of early acute cerebrovascular accidents during OPCAB.

Avoiding aortic clamping during CABG reduces postoperative stroke
This review of 12,079 patients evaluated the effect of aortic manipulation strategies on stroke following CABG. Stroke risk was independently associated with the degree of aortic manipulation, with the no-touch technique having the lowest risk. This suggests that avoiding aortic manipulation may minimize the incidence of stroke following CABG.

074-i * off-pump coronary artery bypass reduces early stroke in octogenarians: a meta-analysis of 18,000 patients
Conclusion: Coronary artery bypass in octogenarians can be performed with low early mortality. Number of grafts is lesser in the OPCABG cohort. While stroke rates are higher with conventional surgery, all other adverse events are comparable. Future randomised trials are needed to define the role of off-pump surgery in this high-risk cohort.

262 * changes in cerebral oximetry and haemodynamics during off-pump coronary artery bypass: mechanism for perioperative stroke?
Conclusion: Cerebral oxygenation may be impaired during OPCAB with delayed recovery by closure despite normalisation of cardiac output. This prolonged desaturation was not artefactual or related to patient posture. We recommend the routine monitoring of cerebral oximetry during OPCAB to prevent brain injury.

Postoperative rescue closure of patent foramen ovale in the clinical setting of acute hypoxemic respiratory failure and stroke following coronary artery bypass surgery.
We describe a case of intraoperative diagnosis and successful deferred percutaneous closure of a patent foramen ovale (PFO) in the clinical setting of acute refractory hypoxemic respiratory failure and new-onset ischemic stroke in an elderly patient after coronary artery bypass graft. Perioperative morbidity (i.e. severe hypoxemia, worsening right ventricular dysfunction, and embolic stroke) that is potentially related to intraoperatively diagnosed PFO during cardiac surgery can complicate management in the Intensive Care Unit and perhaps affect the patient's outcome. Although the PFO closure can be challenging in the clin...

Predictors of Stroke Associated with Coronary Artery Bypass Grafting in Patients with Diabetes Mellitus and Multivessel Coronary Artery Disease
This study assesses demographic and clinical variables associated with perioperative and late stroke in diabetes mellitus patients following multivessel coronary artery bypass grafting (CABG). FREEDOM is the largest randomized trial of diabetic patients undergoing multivessel CABG. FREEDOM patients had improved survival free of death, myocardial infarction or stroke and increased overall survival following CABG compared to percutaneous intervention (PCI). However, the stroke rate was greater following CABG than PCI.

Anticoagulation for stroke prevention in new atrial fibrillation after coronary artery bypass graft surgery

Can we make stroke during cardiac surgery a never event?
Stroke has been and continues to be the Achilles heel of cardiac surgery. Periprocedural neurologic events during cardiac surgery remain prevalent, with stroke reported in 2.0% to 4.6% of patients undergoing cardiac surgery and increasing to at least 12.8% in octogenarians.1-3 The fear of stroke or other adverse neurologic outcomes, including so-called pump head, is a deterrent for patients to undergo the otherwise successful, life-saving operations that we perform.

Off-Pump Coronary Artery Bypass Reduces Early Stroke in Octogenarians: A Meta-Analysis of 18,000 Patients
Conclusions Coronary artery bypass in octogenarians can be performed safely with low early mortality. Although off-pump operations reduce the risk of early stroke, all other adverse events are comparable in on- and off-pump coronary artery bypass operations. Data regarding late mortality is at present limited; however, both on- and off-pump procedures appear to produce comparable survival.

Cerebrovascular Events After a Primary Percutaneous Coronary Intervention Strategy for Acute ST-Segment- Elevation Myocardial Infarction: Analysis From the HORIZONS-AMI Trial Coronary Interventions
Conclusions— In HORIZONS-AMI, cerebrovascular events within 3 years after ST-segment–elevation myocardial infarction in patients undergoing a primary percutaneous coronary intervention management strategy occurred in 2.0% of patients and were most frequent after coronary artery bypass grafting. Cerebrovascular events were often disabling and were strongly associated with high rates of death, reinfarction, recurrent ischemia, and major bleeding.

Stroke associated with coronary artery bypass grafting
Abstract While coronary artery bypass grafting (CABG) has been playing a significant role in the revascularization for ischemic heart disease, neurological complications associated with CABG have been a primary concern. Stroke, although the incidence is low, is one of the most devastating complication of CABG. Many studies have identified the risk factors for stroke with CABG, such as prior stroke, carotid artery stenosis, aortic atherosclerosis, atrial fibrillation and cardiopulmonary bypass. Various rational approaches focusing on individual risk factor have been proposed for the stroke. Prophylactic carotid rev...

Institutional Variation in Mortality After Stroke After Cardiac Surgery: An Opportunity for Improvement
Conclusions Institutional variation, more so than individual patient risk factors, is highly associated with postoperative stroke and FTR rates after stroke after cardiac surgery. Postoperative stroke remains significantly associated with mortality and morbidity. Institutional practice patterns may confer a disproportionate influence on postoperative stroke independent of case mix. Understanding differences between high and low performing centers is essential to improving outcomes, costs, and hospital quality.

Diagnostic accuracy of stroke volume variation measured with uncalibrated arterial waveform analysis for the prediction of fluid responsiveness in patients with impaired left ventricular function: a prospective, observational study
Abstract Uncalibrated arterial waveform analysis enables dynamic preload assessment in a minimally invasive fashion. Evidence about the validity of the technique in patients with impaired left ventricular function is scarce, while adequate cardiac preload assessment would be of great value in these patients. The aim of this study was to investigate the diagnostic accuracy of stroke volume variation (SVV) measured with the FloTrac/Vigileo™ system in patients with impaired left ventricular function. In this prospective, observational study, 22 patients with a left ventricular ejection fraction of 40 % or less und...

Conclusion The incidence of stroke after systematic OPCAB was low. Early and delayed strokes were equally distributed. Stroke mechanisms were predominantly embolic.

Obstructive carotid and/or intracranial artery disease rarely affects the incidence of haemodynamic ischaemic stroke during cardiac surgery: a study on brain perfusion single-photon emission computed tomography with acetazolamide ADULT CARDIAC
CONCLUSIONS It is unusual for CIAD to affect the incidence of haemodynamic ischaemic stroke during cardiac surgery. Brain perfusion SPECT with acetazolamide is effective for narrowing down patients at high risk of ischaemic stroke during cardiac surgery. Meanwhile, the application of brain perfusion single-photon emission tomography should be confined only to patients with obstructive CIAD because it is an expensive examination tool.

AbstractStroke is a major adverse event in patients developing atrial fibrillation (AF) after cardiac surgery. Surgical left atrial appendage amputation/ligation (LAA-A/L) during off-pump coronary artery bypass grafting (OPCAB) is routinely performed in our institution.
