identify patients with CSPH. A training set of 69 patients was used, and results were validatedusing an independent series of 128 patients with compensated cirrhosis from another centre.Results: The combination of Pl count and LSM measurement was more accurate for identifyingCSPH than either marker alone (training cohort AUROC: 0.87 [0.77-0.94] vs. 0.77 [0.66-0.86] and 0.78 [0.66 - 0.87] for platelets and LSM). The optimal risk score was 0.11 (Sens =0.88, Spec = 0.77, PPV = 0.33, NPV = 0.98, accuracy = 78%). Results in the validationcohort confirmed the discriminatory power of this model (AUROC: 0.76 [0.68-0.83]). Wethen tested clinically relevant cut-offs to improve the NPV for CSPH. The NPV for thecombination of Pl ≥ 100 and LSM < 25 kPa was 100% in both the training cohort andvalidation cohort (Table 1). 82 (42%) of patients overall met this criteria. Conclusion: Thecombination of LSM < 25 kPa and Pl ≥ 100 can be used to identify patients with compensatedcirrhosis who do not have CSPH. Our study suggests that patients meeting these criteriado not require endoscopic screening for CSPH, but could be followed with annual LSMand full blood count.

Severity of Bleeding Complications in Cirrhotic Patients Compared to Non-Cirrhotic Patients Treated for Acute Myocardial InfarctionSean Rudnick, Benjamin Shepple, Ellen Keeley, Zachary Henry, Curtis K. Argo, NeeralShah
Background: Little is known regarding the incidence, predictors, and severity of bleedingin cirrhotic patients treated for acute myocardial infarction (MI). Methods: Using the Clinicaldata repository we identified patients age ≥ 18 years from 1/1/2011 to 12/31/12 who wereadmitted with an International Classification of Diseases-9 (ICD-9) code for cirrhosis andan ICD-9 code for acute MI. Inclusion required a diagnosis of cirrhosis based on biopsy orclinical, laboratory, and radiological findings. Acute MI was defined by the American HeartAssociation's 3rd Universal Definition of MI. Thirty one patients met inclusion criteria and31 non-cirrhotic controls with acute MI were identified and matched to cases on a 1:1 basisbased on age, sex, and cardiovascular risk factors including diabetes, known coronary arterydisease, and tobacco use. Bleeding events in cases and controls were compared. The GlobalUse of Strategies to Open Occluded Arteries (GUSTO) bleeding classification was used todefine bleeding events as mild (GUSTO 1), moderate (GUSTO 2), and severe/life-threatening(GUSTO 3) based on clinical criteria. Results: Overall, 23% of cirrhotic patients treated forMI had a bleeding event compared to 6.5% of controls. Less than half (45%) of cirrhoticpatients underwent coronary angiography. Those who underwent coronary angiography hadsignificantly higher bleeding complications compared to those treated medically (43% vs.6%, p<0.03), and were more likely to receive aspirin, clopidogrel, and anticoagulation.There was no statistically significant difference between mean platelet count or INR incirrhotic patients with and without bleeding. In the control group 84% underwent coronaryangiography and 2 had mild, GUSTO 1 bleeding events. Vascular access site appeared toaffect the risk of bleeding as no patients with radial artery access had a bleeding event, but3 patients with femoral artery access experienced bleeding. In the cirrhotic group, 6 patientswho underwent coronary angiography had a bleeding event, while 1 had a bleeding event eventhough they did not undergo coronary angiography. No controls developed gastrointestinalbleeding (GIB). Four cirrhotic patients developed GIB, 2 of these also underwent coronaryangiography. While nearly one-third of the cirrhotic patients had a history of esophagealvarices, only one patient developed a variceal bleed that was successfully managed endoscopi-cally. One cirrhotic patient developed GIB despite not receiving anticoagulation. Conclusions:Bleeding events were more common among cirrhotic patients with MI compared to controls(23% vs. 6.5%) and in those who underwent coronary angiography. The majority of thebleeding events were GUSTO 1-2 and equally distributed between cath-related and GIB.Strategies to reduce the risk of bleeding in cirrhotic patients treated for MI are needed.Severity and Bleeding Site in Patients Treated for Acute Myocardial Infarction

Defining the Factors That Predict the Likelihood of Rebleeding FollowingVariceal LigationMolly Disbrow, M Edwyn Harrison, Hugo E. Vargas, Elizabeth J. Carey, Thomas Byrne,Bashar Aqel
BACKGROUND: Esophageal varices are a common complication in end stage liver disease,seen in 50% of patients with cirrhosis and up to 85% of patients with Child Class C disease.Bleeding from varices occurs at a yearly rate of 5-15% and endoscopic variceal ligation(EVL) is one of the standard treatment modalities in the management and prophylaxisof variceal hemorrhage. However, EVL itself can result in complications including uppergastrointestinal (GI) bleeding. Currently, there are little data describing the factors associatedwith early rebleeding following EVL. AIM 1. Evaluate the rate of complications includingearly upper GI bleeding (within four weeks) of EVL. AIM 2. Describe risk factors that canpredict likelihood of early rebleeding following variceal ligation. METHODS: We conducteda retrospective review of the electronic medical records from November 2007 to June 2010for patients who underwent esophageal variceal ligation for bleeding or prophylaxis ofesophageal varices. Data recorded included age, sex, etiology of liver disease, Childs Class,MELD score, history of GI bleeding, if band ligation was urgent/emergent (within 24 hoursof GI bleeding), number of EVL sessions per patient, GI bleeding within four weeks of EVL,and death within four weeks of EVL. A predictive model using the generalized estimationequation was used to examine factors predicting early bleeding. The variables with p-valueless than or equal to 0.3 were considered and included in the model selection. Backwardelimination was applied to select the set of variables associated with early bleeding, and anyvariable with p-value <0.1 were retained in the model. RESULTS: 156 patients underwenta total of 349 endoscopies for EVL (Table 1). There were 66 (42.6%) women, the meanage of cohort was 58.3 (SD=9.93) years, with 22 (14.7%) Child Class C.). 76 patients(49.4%) had history of prior bleeding, and 36 (23.2%) underwent EVL emergently/urgently(within 24 hours of admission for GI bleeding), the rest of procedures were done for primaryprophylaxis. Post banding chest pain was seen in 9 patients (7.7%). Six patients (3.9%) hadupper GI bleeding after EVL with mean time to rebleed 11.2 days (SD=11.2). Three patients(1.9%) died within four weeks of EVL. Predictive model analysis found that the MELDscore, indication for banding, and use of B-blockers to be significant predictors for earlybleeding after EVL (Table 2). CONCLUSIONS: Rebleeding rate after EVL was 3.9% withestimated mortality of 1.9%. MELD score, acute indication for EVL, and use of B-blockerswere predictive of early rebleeding.Table 1: Clinical Characteristics and Demographics

Characteristics of Cirrhotic Patients With Concomitant Portal VeinThrombosis and Non-Splanchnic Venous ThromboembolismJeffrey LaFond, Neil D. Shah, Nicolas M. Intagliata, Patrick G. Northup, Stephen H.Caldwell, Neeral L. Shah
Background: It is well known that cirrhotic patients develop both portal vein thrombosis(PVT) and non-splanchnic venous thromboembolism (NSVTE). Studies have shown theprevalence of PVT in patients with cirrhosis is 15-30%. There are no guidelines for thetreatment of either PVT or NSVTE in patients with cirrhosis. Also, to our knowledge noone has studied the characteristics of patients with both NSVTE and PVT. We evaluated acohort of cirrhotic patients with NSVTE to investigate whether there are any characteristicsor associations for those with concomitant PVT. Methods: 147 subjects were initially identifiedvia the clinical data repository at a large academic tertiary care medical center by relevantICD9 codes. The medical record was retrospectively reviewed for the presence of NSVTEon diagnostic imaging and cirrhosis confirmed by either liver biopsy or radiographic evidencein conjunction with the appropriate clinical presentation. 50 patients met the inclusioncriteria and were followed for a 6 month period. Records were reviewed from September2009 to December 2012. Data regarding demographics, cancer history, prior history ofNSVTE or PVT, presence of central venous catheter (CVC), history of esophageal varicesand related bleeding, and relevant laboratory data were compiled. Patients with NSVTE andPVT were compared to those with NSVTE only. Results: Of the 50 patients, 9 (18%) patientswere found to have a PVT. PVT patients were more likely to have a history of esophageal
