A regional pharmacoinvasive PCI strategy incorporating selected bleeding avoidance strategies.

BACKGROUND: Pharmacoinvasive therapy (PIT) is a potential treatment for ST-segment elevation myocardial infarction patients who are not able to achieve primary percutaneous intervention (PCI) within guideline-recommended time limits. The risk for bleeding complications with PIT has not been studied in the setting of routine use of two selected bleeding avoidance strategies (BAS): bivalirudin and vascular closure devices. METHODS: We analyzed a contemporary multicenter registry (2009-2013) of consecutive patients undergoing PCI as part of a 10-hospital regional algorithm involving one PCI center and nine transfer centers: PIT for hospitals greater than 60 min (N=140), and primary PCI if less than 60-min travel time to the PCI center (N=346). We compared the risk for Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction (HORIZONS) major bleeding among patients undergoing PIT versus primary PCI in the setting of routine use of selected BAS and determined the independent predictors of major bleeding in the entire cohort. RESULTS: The PIT patients had a median travel time of 103±49 min, were more frequently female, had a higher incidence of renal failure, and had a lower frequency of cardiogenic shock compared with the primary PCI group. BAS were routine and similar in both groups. Rates of death, stroke, and ischemic and major bleeding outcomes were similar between the two groups, and the length of stay was shorter in the PIT group. Multivariate logistic models indicated that two independent predictors of major bleeding were cardiac arrest [odds ratio (OR)=3.89, 95% confidence interval (CI): 1.2-12.1, P=0.02] and bailout glycoprotein IIb/IIIa inhibitor utilization (OR=3.29, 95% CI: 1.1-9.6, P=0.03). The PIT strategy in conjunction with selected BAS did not predict major bleeding (OR=2.1, 95% CI: 0.85-5.44, P=0.11). CONCLUSION: Bleeding and ischemia rates were similar between the PIT and primary PCI strategies in the setting of routine use of selected BAS; further study on a broader range of BAS including the radial approach may be warranted. Cardiac arrest and bailout glycoprotein IIb/IIIa inhibitor, but not PIT in conjunction with selected BAS, are independent predictors of bleeding risk in a regional ST-segment elevation myocardial infarction population.

Initial assessment and management of patients with nonvariceal upper gastrointestinal bleeding.

Upper gastrointestinal bleeding (UGIB) is a substantial clinical and economic burden, with an estimated mortality rate between 3% and 15%. The initial management starts with hemodynamic assessment and resuscitation. Blood transfusions may be needed in patients with low hemoglobin levels or massive bleeding, and patients who are anticoagulated may require administration of fresh frozen plasma. Patients with significant bleeding should be started on a proton-pump inhibitor infusion, and if there is concern for variceal bleeding, an octreotide infusion. Patients with UGIB should be stratified into low-risk and high-risk categories using validated risk scores. The use of these risk scores can aid in separating low-risk patients who are suitable for outpatient management or early discharge following endoscopy from patients who are at increased risk for needing endoscopic intervention, rebleeding, and death. Upper endoscopy after adequate resuscitation is required for most patients and should be performed within 24 hours of presentation. Key to improving outcomes is appropriate initial management of patients presenting with UGIB.

Influence of use of a vascular closure device on incidence and surgical management of access site complications after percutaneous interventions.

AIM: The study aimed to evaluate vascular access site complications (ASCs) after percutaneous interventions (PIs) in our institution for changes in annual incidence and surgical management after increased usage of a vascular closure device (VCD; in all cases: Angioseal™). MATERIAL AND METHODS: All patients who underwent repair of arterial pseudo-aneurysms or access site stenosis/occlusion leading to leg ischaemia (LI) or new-onset disabling claudication (CI) after PIs between 2001 and 2008 were included. Annual rates of procedures and methods of repair of ASC were evaluated. RESULTS: After a total of 58 453 PIs, 352 patients (0.6%) were operated on for: pseudo-aneurysms (n = 300; 0.51%); and local stenosis/occlusion leading to LI/CI (n = 52; 0.09%). Numbers increased significantly with more widespread VCD use: group A (2001-2004: 2860 VCDs; 28 284 PIs; 10.1%): n = 132 (0.47%); and group B (2005-2008: 11,660 VCDs; 30,169 PIs; 38.6%): n = 220 (0.73%) (p < 0.001). In contrast to similar rates of pseudo-aneurysms (group A: n = 124; 0.44%; group B: n = 176; 0.58%; not significant), a significant increase of operations for local stenoses/occlusions was seen with widespread VCD use: n = 8 versus n = 44 (p < 0.001). CONCLUSIONS: In the era of VCDs, complications are rare. However, use of these devices is not without complications, and may require complex reconstructions.
