- Background In recent studies of primary percutaneous coronary intervention (PCI), bivalirudin compared with heparin has been associated with increased risk of stent thrombosis (ST). Our aim was to describe incidence and outcome of definite, early ST in a large contemporary primary PCI population divided in antithrombotic therapy subgroups. Methods and Results A prospective, observational cohort study of all 31,258 ST-elevation myocardial infarction patients who received a stent in Sweden from January 2007 to July 2014 in the SWEDEHEART registry was conducted. Patients were divided into 3 groups: bivalirudin, heparin alone, or glycoprotein IIb/IIIa inhibitor treated. Primary outcome measure was incidence of definite early ST (within 30 days of PCI). Secondary outcomes included all-cause mortality. Incidence of early ST was low, regardless of bivalirudin, heparin alone, or glycoprotein IIb/IIIa inhibitor treatment (0.84%, 0.94%, and 0.83%, respectively). All-cause mortality at 1 year was 20.7% for all ST patients (n = 265), compared with 9.1% in those without ST (n = 31,286; P < .001). Patients with ST days 2-30 had numerically higher all-cause mortality at 1 year compared with patients with ST days 0-1 (23% vs 16%, P =.20). Conclusion In this real-world observational study of 31,258 ST-elevation myocardial infarction patients, the incidence of early ST was low, regardless of antithrombotic treatment strategy. Early ST was associated with increased mortality. Numerically higher all-cause mortality at 1 year was noted with ST days 2-30 compared with ST days 0-1 post-PCI.

- Objectives To analyze the clinical outcome of percutaneous coronary intervention (PCI) using the Xience drug eluting stent (DES) versus other modern DES.Methods This retrospective study based on the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) analyzed the outcome of PCI using Xience versus other commonly used modern DES, 2007 to 2017. The primary outcome measure was a combination of all-cause death, myocardial infarction (MI) and revascularisation with PCI. Angiographical outcome measures were in-stent restenosis (ISR) and stent thrombosis (ST).Results Rates of the primary outcome measure for Xience and other DES were 31.9% and 28.2% respectively, adjusted hazard ratio (HR) 0.99 (95% CI 0.95-1.03). Crude rates of ISR were 2.9% versus 2.1% over 4.3 and 2.9 years respectively, adjusted HR 0.93 (95% CI 0.81-1.06). Crude rates of ST were 0.9% versus 0.7%, adjusted HR 1.07 (95% CI 0.82-1.39). Results were consistent in all sensitivity analyses.Conclusions This nationally complete, real-world study confirms that Xience is a safe and effective DES with low-event rates of ISR and ST. Compared with a control group containing a large proportion of thinner strut stents and absorbable polymers, Xience exhibits similar results in all important clinical endpoint

- Aims: The aim of the stud was to compare outcomes in unfractionated heparin (UM) and bivalirudintreated patients undergoing primary percutaneous coronary intervention (PPCI). Methods and results: This observational study contained 20,612 PPCT patients treated with either GM monotherapv or bivalirudin with or without concomitant UFE. Patients with oral anticoagulant or glycoprotein IIb/IIIa inhibitor (GPI) treatment were excluded. The primary outcome measure was definite early stent thrombosis (Si) that occurred at low and similar rates in UNA only and bivalirudin-treated patients: 0.9% vs. 0.8% (adjusted hazard ratio [HR] 1.08, 95% confidence interval [CI]: 0.7-1.65). All-cause death at 30 days occurred in 6.9% vs. 5.4% of patients (adjusted HR 1.23, 95% Cl: 1.05-1.44) and within 365 days in 12.1% vs. 8.9% (adjusted HR 1.34, 95% CI: 1.19-1.52) in the two groups, respectively. The incidence of major bleeding within 30 days was 0.8% vs. 0.6% (adjusted HR 1.54, 95% CI: 0.97-2.45). The incidence of reinfarction within 365 days and stroke within 30 days was similar between groups. Conclusions: In this large, nationwide observational study we found low and similar rates of early ST in UFH only and bivalirudin-treated patients undergoing primary PCI. Mortality was higher in IJFH compared with bivalirudin-treated patients.

- Background-Long-term disease progression after myocardial infarction (MI) is inadequately understood. We evaluated the pattern and angiographic properties (culprit lesion [CL]/non-CL [NCL]) of recurrent MI (re-MI) in a large real-world patient population. Methods and Results--Our observational study used prospectively collected data in 108 615 patients with first-occurrence MI enrolled in the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) between July 1, 2006 and November 29, 2014. During follow-up (median, 3.2 years), recurrent hospitalization for MI occurred in 11 117 patients (10.2%). Of the patients who underwent coronary angiography for the index MI, a CL was identified in 44 332 patients. Of those patients, 3464 experienced an re-MI; the infarct originated from the NCL in 1243 patients and from the CL in 655 patients. In total, 1566 re-MIs were indeterminate events and could not be classified as NCL or CL re-MIs. The risk of re-MI within 8 years related to the NCL was 0.06 (95% confidence interval [CI], 0.05-0.06), compared with 0.03 (95% CI, 0.02-0.03) for the CL. There were no large differences in baseline characteristics of patients with subsequent NCL versus CL re-MIs. Independent predictors of NCL versus CL re- MI were multivessel disease (odds ratio, 2.29; 95% CI, 1.87-2.82), male sex (odds ratio, 1.36; 95% CI, 1.09-1.71), and a prolonged time between the index and re-MI (odds ratio, 1.16; 95% CI, 1.10- 1.22). Conclusions--In a large cohort of patients with first-occurrence MI undergoing percutaneous coronary intervention, the risk of re-MI originating from a previously untreated lesion was twice higher than the risk of lesions originating from a previously stented lesion.

- OBJECTIVES: The aim of this study was to test the noninferiority of eptifibatide relative to abciximab in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). BACKGROUND: Glycoprotein IIb/IIIa inhibitors are recommended by international guidelines in patients with acute coronary syndromes undergoing PCI. Abciximab is recommended with a higher level of evidence than eptifibatide in patients with STEMI. No large, prospective, randomized trial comparing abciximab and eptifibatide has been published. METHODS: All (n = 11,479) STEMI patients in Sweden who underwent primary PCI and received either eptifibatide or abciximab from 2004 to 2007 were derived from the SCAAR (Swedish Coronary Angiography and Angioplasty Registry). The primary end point was death or myocardial infarction (MI) during 1-year follow-up, with adjustment for baseline differences with a multivariate logistic regression analysis including propensity score. The pre-specified noninferiority margin was set to 1.29. RESULTS: The combined end point occurred in 353 of 2,355 patients (15.0%) treated with eptifibatide and in 1,432 of 9,124 patients (15.7%) treated with abciximab. The unadjusted odds ratio (OR) for eptifibatide versus abciximab was 0.95 (95% confidence interval [CI]: 0.84 to 1.08). Multivariate adjustment (n = 11,317) confirmed noninferiority, with an OR of 0.94 (95% CI: 0.82 to 1.09). The adjusted secondary end points of death and MI separately also showed noninferiority, with ORs of 0.99 (95% CI: 0.82 to 1.19) and 0.88 (95% CI: 0.73 to 1.05), respectively. CONCLUSIONS: This large registry study suggests that eptifibatide is noninferior to abciximab in patients with STEMI undergoing primary PCI with respect to death or MI during 1 year, thereby supporting the use of either drug in clinical practice.
