- Background We examined the prevalence of undiagnosed diabetes or prediabetes and associations with ischemic outcomes among non-ST-segment elevation acute coronary syndrome (ACS) patients. Methods We categorized 8795 EARLY ACS trial patients into one of the following groups: "known diabetes" (n = 2860 [32.5%]; reported on the case report form), "undiagnosed diabetes" (n = 1069 [12.2%]; no diabetes history and fasting glucose >= 126 mg/dL or hemoglobin A(1c) >= 6.5%), "prediabetes" (n = 947 [10.8%]; fasting glucose >= 110 to <126 mg/dL, or " normal" (n = 3919 [44.5%]). Adjusted associations of known diabetes, undiagnosed diabetes, and prediabetes (versus normal) with 30-day and 1-year outcomes were determined. Results Undiagnosed diabetes was associated with greater 30-day death or myocardial infarction (MI) (ORadj 1.28, 95% CI 1.05-1.57), driven primarily by greater 30-day mortality (ORadj 1.65, 95% CI 1.09-2.48). Known diabetic patients had 30-day death or MI outcomes similar to those of normal patients, but 30-day mortality was higher (ORadj 1.40, 95% CI 1.01-1.93). Prediabetic patients had 30-day death or MI outcomes similar to those of normal patients. One-year mortality was greater among known diabetic patients (HRadj 1.38, 95% CI 1.13-1.67) but not among those with undiagnosed diabetes or prediabetes. Conclusions Undiagnosed diabetes and prediabetes were common among high-risk non-ST-segment elevation ACS patients. Routine screening for undiagnosed diabetes may be useful since these patients seem to have worse short-term outcomes and deserve consideration of alternative management strategies.

- Aim The primary objective was to compare apixaban to heparin/ vitamin K antagonist (VKA) in patients with atrial fibrillation (AF) and <= 48 h anticoagulation prior to randomization undergoing cardioversion. Methods One thousand five hundred patients were randomized. The apixaban dose of 5mg b.i.d. was reduced to 2.5 mg b.i.d. in patients with two of the following: age >= 80 years, weight <= 60 kg, or serum creatinine >= 133 mu mol/L. To expedite cardioversion, at the discretion of the investigator, imaging and/or a loading dose of 10 mg (down-titrated to 5 mg) was allowed. The endpoints for efficacy were stroke, systemic embolism (SE), and death. The endpoints for safety were major bleeding and clinically relevant non-major (CRNM) bleeding. Results There were 1038 active and 300 spontaneous cardioversions; 162 patients were not cardioverted. Imaging was performed in 855 patients, and 342 received a loading dose of apixaban. Comparing apixaban to heparin/VKA in the full analysis set, there were 0/753 vs. 6/747 strokes [relative risk (RR) 0; 95% confidence interval (95% CI) 0-0.64; nominal P = 0.015], no SE, and 2 vs. 1 deaths (RR 1.98; 95% CI 0.19-54.00; nominal P > 0.999). In the safety population, there were 3/735 vs. 6/721 major (RR 0.49; 95% CI 0.10-2.07; nominal P = 0.338) and 11 vs. 13 CRNM bleeding events (RR 0.83; 95% CI 0.34-1.89; nominal P = 0.685). On imaging, 60/61 with thrombi continued randomized treatment; all (61) were without outcome events. Conclusions Rates of strokes, systemic emboli, deaths, and bleeds were low for both apixaban and heparin/VKA treated AF patients undergoing cardioversion.

- Background: Guidelines suggest that "upstream" P2Y(12) receptor antagonists should be considered in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS).Hypothesis: Early use of ticagrelor in patients managed with an invasive strategy would be more effective than clopidogrel because of its more rapid onset of action and greater potency.Methods: In the PLATO trial, 6792 NSTE-ACS patients were randomized to ticagrelor or clopidogrel (started prior to angiography) and underwent angiography within 72 hours of randomization. We compared efficacy and safety outcomes of ticagrelor vs clopidogrel as a function of "early" (<3h) vs "late" (>= 3h) time to angiography. Adjusted Cox proportional hazards models evaluated interaction between randomized treatment and time from randomization to angiography on subsequent outcomes.Results: Overall, a benefit of ticagrelor vs clopidogrel for cardiovascular death/myocardial infarction/stroke was seen at day 7 (hazard ratio [HR]: 0.67, P = 0.002), day 30 (HR: 0.81, P = 0.042), and 1 year (HR: 0.80, P = 0.0045). There were no significant interactions in the <3h vs >= 3h groups at any timepoint. For major bleeding, overall there was no significant increase (HR: 1.04, 95% confidence interval: 0.85-1.27); but there was a significant interaction with no difference between ticagrelor and clopidogrel in the early group (HR: 0.79), but higher bleeding risk with ticagrelor in the late angiography group, at 7 days (HR: 1.51, P-int = 0.002). Patterns were similar at 30 days and 1 year.Conclusions: The benefit of ticagrelor over clopidogrel was consistent in those undergoing early and late angiography, supporting upstream use of ticagrelor

- Background: Regional differences in the profile and prognosis of non-ST-segment elevation acute coronary syndrome (NSTE ACS) patients treated with medical management after angiography remain uncertain.Methods and Results: Using data from the Early Glycoprotein IIb/IIIa Inhibition in Non-ST-Segment Elevation Acute Coronary Syndromes (EARLY ACS) trial, we examined regional variations in the use of an in-hospital medical management strategy in NSTE ACS patients who had significant coronary artery disease (CAD) identified during angiography, factors associated with the use of a medical management strategy, and 1-year mortality rates. Of 9406 patients, 8387 (89%) underwent angiography and had significant CAD; thereafter, 1766 (21%) were treated solely with a medical management strategy (range: 18% to 23% across 4 major geographic regions). Factors most strongly associated with a medical management strategy were negative baseline troponin values, prior coronary artery bypass grafting, lower baseline hemoglobin values, and greater number of diseased vessels; region was not a significant factor. One-year mortality was higher among patients treated with a medical management strategy compared with those who underwent revascularization (7.8% versus 3.6%; adjusted hazard ratio, 1.46; 95% CI, 1.21-1.76), with no significant interaction by region (interaction probability value=0.42).Conclusions: Approximately 20% of NSTE ACS patients with significant CAD in an international trial were treated solely with an in-hospital medical management strategy after early angiography, with no regional differences in factors associated with medical management or the risk of 1-year mortality. These findings have important implications for the conduct of future clinical trials, and highlight global similarities in the profile and prognosis of medically managed NSTE ACS patients.
