Stroke is one of the most devastating complications after coronary artery bypass graft (CABG) surgery, entailing permanent disability, a 3–6 fold increased risk of mortality, an incremental hospital resource consumption and a longer length of hospital stay. Notwithstanding advances in surgical, anaesthetic and medical management across the last 10 years, the risk of stroke after CABG has not significantly declined, likely because an older and sicker population is now deemed suitable to undergo CABG. The pathogenesis of stroke is multifactorial, but two variables are believed to play a major role – cerebral embolisation of atheromatous debris arising from the ascending aorta during surgical manipulation and hypoperfusion during surgery. Identification of vulnerable patients at increased risk of stroke before CABG is of paramount importance for the surgical decision-making approach and informed consent. Several models including demographic, clinical and procedural variables have been developed to risk-stratify the hazard of stroke in patients undergoing CABG, but identification of severe atherosclerosis of the ascending aorta and pre-existing cerebrovascular disease are key determinants for appropriate risk stratification and decision-making. Atherosclerotic disease of the ascending aorta can be identified before surgery using transoesophageal echocardiography, computed tomography and magnetic resonance imaging. However, intra-operative ultrasound scanning of the ascending aorta is the diagnostic tool with the best sensitivity and specificity for the detection of atheromatous debris in the ascending aorta. Although many investigators have advocated the use of off-pump CABG to minimise the risk of peri-operative stroke, results from randomised trials and meta-analyses have been inconsistent. Anaortic approaches, including total arterial revascularisation within situgrafting of both mammary arteries, or the use of the HEARTSTRING® seal device avoid any manipulation of the aorta, thus potentially minimising the risk of stroke in high-risk patients. Assessment and treatment of severe carotid artery disease, and aggressive and prompt treatment of post-operative atrial fibrillation are other important strategies that should be routinely implemented to reduce the risk of stroke in patients undergoing CABG.

Background Despite the fact that obesity is a known risk factor for cardiovascular disease, many studies have failed to demonstrate that obesity is independently associated with an increased risk of cardiovascular morbidity and mortality in nondiabetic patients undergoing coronary artery bypass graft surgery. The authors investigated the influence of obesity on adverse postoperative outcomes in diabetic and nondiabetic patients after primary coronary artery bypass surgery. Methods A retrospective cohort study of patients undergoing primary coronary artery bypass surgery (n = 9,862) between January 1995 and December 2004 at the Texas Heart Institute was performed. Diabetic (n = 3,374) and nondiabetic patients (n = 6,488) were classified into five groups, according to their body mass index: normal weight (n = 2,148), overweight (n = 4,257), mild obesity (n = 2,298), moderate obesity (n = 785), or morbid obesity (n = 338). Multivariate, stepwise logistic regression was performed controlling for patient demographics, medical history, and preoperative medications to determine whether obesity was independently associated with an increased risk of adverse postoperative outcomes. Results Obesity in nondiabetic patients was not independently associated with an increased risk of adverse postoperative outcomes. In contrast, obesity in diabetic patients was independently associated with a significantly increased risk of postoperative respiratory failure (odds ratio [OR], 2.26; 95% confidence interval [CI], 1.41-3.61; P < 0.001), ventricular tachycardia (OR, 2.27; 95% CI, 1.18-4.35; P < 0.02), atrial fibrillation (OR, 1.56; 95% CI, 1.03-2.38; P < 0.04), atrial flutter (OR, 2.38; 95% CI, 1.29-4.40; P < 0.01), renal insufficiency (OR, 1.66; 95% CI, 1.10-3.41; P < 0.03), and leg wound infection (OR, 5.34; 95% CI, 2.27-12.54; P < 0.001). Obesity in diabetic patients was not independently associated with an increased risk of mortality, stroke, myocardial infarction, sepsis, or sternal wound infection. Conclusion Obesity in diabetic patients is an independent predictor of worsened postoperative outcomes after primary coronary artery bypass graft surgery.

Abstract Introduction: Skeletal events, including fractures, form an important part of the clinical spectrum of PCDs. Skeletal surveys, even though less sensitive than MRI, remain the usual method of screening for lytic lesions and fractures in these patients but may miss subtle abnormalities. Patients undergoing a CABG normally require a midline sternal incision, which may increase the risk of a skeletal event. Patients with PCDs also have an increased risk of infection, thrombosis, and renal failure. To our knowledge, there is no published data about complications of cardiothoracic surgery in these patients. We hypothesized that patients with PCDs will have a higher risk of complications when compared to those without such history. Methods: Data on patients who underwent non-urgent coronary artery bypass graft (CABG) surgery from 2007 to 2011 was obtained by querying the Healthcare Cost and Utilization State Inpatient Databases for Florida and California. Information was available only for the inpatient stay plus a 30-day follow-up period. Diagnoses of multiple myeloma and monoclonal gammopathy of unknown significance (MGUS) were identified using ICD-9-CM codes. Mixed-effects logistic models were used to measure the association between PCDs and postoperative sternal complications controlling for demographics and comorbidity. Secondary outcomes of study in bivariate analysis included postoperative complications and 30-day readmission rates. Results: A total of 54,422 patients who underwent non-urgent CABG were identified. Of those patients, 500 were known to have a PCD. Ninety two percent of those patients (462 out of 500) had a diagnosis of MGUS. Median age was 66.6 years for the control group and 65.4 years in the PCDs group, and the male to female ratio was equal in both cohorts. In the PCD group, there was a statistically significant higher incidence of anemia, obesity, and renal failure prior to surgical intervention. Sternal infections occurred in 519 (1%) of the patients in the control group versus 18 (3.6%) of the patients in PCDs group (p<0.001). The 30-day all cause readmission rate was similar between the two groups but the 30-day sternal complication rate was significantly higher in the PCDs group (6.8% vs 3.7%; p<0.001). The odds ratio of sternal infection was 3.84 (CI 2.38-6.20) and the odds ratio of sternal dehiscence was 3.87 (CI 1.98-7.57) in the PCDs group when compared to the control group, both of which are statistically significant. Similarly, the odds ratio of sternal complications at 30-days was 1.92 (CI 1.35-2.73) in the PCDs group when compared to the control group. There were no statistically significant differences in the rates of postoperative myocardial infarctions, strokes, urinary tract infections, acute kidney injury, pneumonias, deep venous thrombosis, and gastrointestinal complications between the two cohorts. Conclusions: Our data shows that patients with PCDs have a lower hemoglobin level, renal insufficiency, and are obese at the time of coronary bypass surgery. It is important to note that the majority of the subjects in our study population had MGUS, a condition usually associated with little morbidity. Nonetheless, our cohort of patients with PCDs had a significantly increased risk of sternal wound infection and dehiscence. The treating physicians should be aware of these risks and patients should be informed. Prospective studies will be necessary to confirm and extend these findings.

Increased Risk

SummaryPlatelet dysfunction can be a major factor in excessive bleeding following cardiopulmonary bypass (CBP). A rapid, specific and sensitive method to identify platelet dysfunction would be a useful tool for identifying patients at an increased risk of bleeding. The ability of PFA100™, an in vitro bleeding test, to predict increased bleeding risk linked to platelet dysfunction was tested in 146 patients undergoing primary coronary artery bypass graft. Blood samples were taken the day before surgery, and 15 min and 5 h after heparin neutralization. The preoperative closure times (CT), i. e. the time required for platelets in citrated whole blood to occlude an aperture cut into a membrane coated with collagen plus either epinephrine (CTEPI) or adenosine diphosphate (CTADP) were longer in blood-group-O patients than in patients with other groups. The 15 min postoperative values were significantly longer from preoperative values essentially owing to CBP-induced hemodilution. Interestingly, 5 h after CBP, a significant reduction in CT values probably reflected platelet hyperaggregability. No correlation was found between calculated blood loss (CBL) and either preoperative or postoperative PFA values.
