- We compared combination fibrinolytic plus glycoprotein IIb/IIIa inhibitor therapy with stand-alone fibrinolysis with respect to speed and stability of reperfusion in patients who had acute ST-segment elevation myocardial infarction; data were obtained from 654 patients in 4 trials (Integrilin to Manage Platelet Aggregation to Combat Thrombosis in Acute Myocardial Infarction, Platelet Aggregation Receptor Antagonist Dose Investigation and Reperfusion Gain in Myocardial Infarction, Integrilin and Tenecteplase in Acute Myocardial Infarction, and the Fifth Global Use of Strategies to Open Occluded Coronary Arteries) that compared thrombolytics plus lamifiban, eptifibatide, or abciximab with standard thrombolysis. We found significantly faster and more stable ST-segment recovery with combination therapy starting at 60 minutes (56.7% vs 48.0% with >/=50% ST-segment resolution, p = 0.03) and sustained over 180 minutes after drug administration; this transient benefit may suggest a time frame when more optimal percutaneous coronary intervention can be performed.

- BACK GROUND Data on PCSK9 inhibition in chronic kidney disease (CKD) is limited. OBJECTIVES The purpose of this study was to compare outcomes with evolocumab and placebo according to kidney function. METHODS The FOURIER (Further Cardiovascular Outcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk) trial randomized individuals with clinically evident atherosclerosis and low-density lipoprotein cholesterol (LDL-C) amp;gt;= 70 mg/dl or non-high-density lipoprotein cholesterol amp;gt;= 100 mg/dl to evolocumab or placebo. The primary endpoint (cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization), key secondary endpoint (cardiovascular death, myocardial infarction, or stroke), and safety were analyzed according to chronic kidney disease (CKD) stage estimated from CKD-epidemiology estimated glomerular filtration rate. RESULTS There were 8,077 patients with preserved kidney function, 15,034 with stage 2 CKD, and 4,443 with amp;gt;= stage 3 CKD. LDL-C reduction with evolocumab compared with placebo at 48 weeks was similar across CKD groups at 59%, 59%, and 58%, respectively. Relative risk reduction for the primary endpoint was similar for preserved function (hazard ratio [HR]: 0.82; 95% CI: 0.71 to 0.94), stage 2 (HR: 0.85; 95% CI: 0.77 to 0.94), and stage amp;gt;= 3 CKD (HR: 0.89; 95% CI: 0.76 to 1.05); p(int) = 0.77. Relative risk reduction for the secondary endpoint was similar across CKD stages (p(int) = 0.75)-preserved function (HR: 0.75; 95% CI: 0.62 to 0.90), stage 2 (HR: 0.82; 95% CI: 0.72 to 0.93), stage amp;gt;= 3 (HR: 0.79; 95% CI: 0.65 to 0.95). Absolute RRs at 30 months for the secondary endpoint were -2.5% (95% CI: -0.4% to -4.7%) for stage amp;gt;= 3 CKD compared with -1.7% (95% CI: 0.5% to -2.8%) with preserved kidney function. Adverse events, including estimated glomerular filtration rate decline, were infrequent and similar regardless of CKD stage. CONCLUSIONS LDL-C lowering and relative clinical efficacy and safety of evolocumab versus placebo were consistent across CKD groups. Absolute reduction in the composite of cardiovascular death, MI, or stroke with evolocumab was numerically greater with more advanced CKD. (C) 2019 by the American College of Cardiology Foundation.

- BACKGROUND Intensive low-density lipoprotein cholesterol therapy with ezetimibe/simvastatin in IMPROVE-IT (IMProved Reduction of Outcomes: Vytorin Efficacy International Trial) significantly reduced the first primary endpoint (PEP) in patients post-acute coronary syndrome (ACS) compared to placebo/simvastatin. OBJECTIVES This analysis tested the hypothesis that total events, including those beyond the first event, would also be reduced with ezetimibe/simvastatin therapy. METHODS All PEP events (cardiovascular [CV] death, myocardial infarction [MI], stroke, unstable angina [UA] leading to hospitalization, coronary revascularization >= 30 days post-randomization) during a median 6-year follow-up were analyzed in patients randomized to receive ezetimibe/simvastatin or placebo/simvastatin in IMPROVE-IT. Negative binomial regression was used for the primary analysis. RESULTS Among 18,144 patients, there were 9,545 total PEP events (56% were first events and 44% subsequent events). Total PEP events were significantly reduced by 9% with ezetimibe/simvastatin vs placebo/simvastatin (incidence-rate ratio [RR]: 0.91; 95% confidence interval [CI]: 0.85 to 0.97; p = 0.007), as were the 3 pre-specified secondary composite endpoints and the exploratory composite endpoint of CV death, MI, or stroke (RR: 0.88; 95% CI: 0.81 to 0.96; p = 0.002). The reduction in total events was driven by decreases in total nonfatal MI (RR: 0.87; 95% CI: 0.79 to 0.96; p = 0.004) and total NF stroke (RR: 0.77; 95% CI: 0.65 to 0.93; p = 0.005). CONCLUSIONS Lipid-lowering therapy with ezetimibe plus simvastatin improved clinical outcomes. Reductions in total PEP events, driven by reductions in MI and stroke, more than doubled the number of events prevented compared with examining only the first event. These data support continuation of intensive combination lipid-lowering therapy after an initial CV event.

- Background: The efficacy and safety of non-vitamin-K antagonist oral anticoagulants (NOACs) across the spectrum of body mass index (BMI) and body weight (BW) remain uncertain. Methods: We analyzed data from COMBINE AF (A Collaboration Between Multiple Institutions to Better Investigate Non-Vitamin K Antagonist Oral Anticoagulant Use in Atrial Fibrillation), which pooled patient-level data from the 4 pivotal randomized trials of NOAC versus warfarin in patients with atrial fibrillation. The primary efficacy and safety outcomes were stroke or systemic embolic events (stroke/SEE) and major bleeding, respectively; secondary outcomes were ischemic stroke/SEE, intracranial hemorrhage, death, and the net clinical outcome (stroke/SEE, major bleeding, or death). Each outcome was examined across BMI and BW. Because few patients had a BMI <18.5 kg/m(2) (n=598), the primary analyses were restricted to those with a BMI >= 18.5 kg/m(2). Results: Among 58 464 patients, the median BMI was 28.3 (interquartile range, 25.2-32.2) kg/m(2), and the median BW was 81.0 (interquartile range, 70.0-94.3) kg. The event probability of stroke/SEE was lower at a higher BMI irrespective of treatment, whereas the probability of major bleeding was lower at a higher BMI with warfarin but relatively unchanged across BMI with NOACs. NOACs reduced stroke/SEE overall (adjusted hazard ratio [HRadj], 0.80 [95% CI, 0.73-0.88]; P<0.001), with a generally consistent effect across BMI (P-trend across HRs, 0.48). NOACs also reduced major bleeding overall (HRadj, 0.88 [95% CI, 0.82-0.94]; P<0.001), but with attenuation of the benefit at a higher BMI (trend test across BMI [P-trend], 0.003). The overall treatment effects of NOACs versus warfarin for secondary outcomes were consistent across BMI, with the exception of the net clinical outcome and death. While these outcomes were overall reduced with NOACs (net clinical outcome, HRadj, 0.91 [95% CI, 0.87-0.95]; P<0.001; death, HRadj, 0.91 [95% CI, 0.86-0.97]; P=0.003), these benefits were attenuated at higher BMI (P-trend, 0.001 and 0.08, respectively). All findings were qualitatively similar when analyzed across BW. Conclusions: The treatment effect of NOACs versus warfarin in atrial fibrillation is generally consistent for stroke/SEE across the spectrum of BMI and BW, whereas the reduction in major bleeding is attenuated in those with higher BMI or BW. Death and the net clinical outcome are overall reduced with NOACs over warfarin, although there remain uncertainties for these outcomes at a very high BMI and BW.

- Aim This retrospective chart review was designed to evaluate physician adherence to the prescribing information for fondaparinux regarding adjunctive anticoagulant use during percutaneous coronary intervention (PCI) in patients with an acute coronary syndrome (ACS). Methods and results Medical record abstractors at each site obtained information regarding the use of fondaparinux and adjunctive anticoagulants during PCI. Physician adherence to fondaparinux prescribing information regarding the administration of an adjunctive anticoagulant during PCI was estimated using generalized estimating equations. This retrospective study, conducted in 2008-2010, included a total of 1056 patient records from 27 sites across 6 countries (Canada, France, Germany, Greece, Poland, and Sweden). Over 98% of patients had been treated with fondaparinux at the recommended 2.5 mg dose. Use of adjunctive anticoagulant during PCI was 97.5%, giving an adjusted adherence rate of 98.8% (95% confidence interval: 0.97-0.99), with 86.3% of patients receiving unfractionated heparin. Although the sub-group of patients with ST-elevation myocardial infarction who underwent primary PCI was too small to make a definitive conclusion, 70.4% of the 159 patients did not receive fondaparinux immediately prior to (<24 h) or during primary PCI, suggesting that their treating physicians may have been adherent to the prescribing information. Conclusion Physician adherence to the prescribing information for adjunctive anticoagulation during PCI in patients with an ACS receiving fondaparinux was high. The results were consistent in each of the six countries and across patient sub-groups.

- Antithrombotic agents are an integral component of the medical regimens and interventional strategies currently recommended to reduce thrombotic complications in patients with acute coronary syndromes (ACS). Despite great advances with these therapies, associated high risks for thrombosis and hemorrhage remain as the result of complex interactions involving patient comorbidities, drug combinations, multifaceted dosing adjustments, and the intricacies of the care environment. As such, the optimal combinations of antithrombotic therapies, their timing, and appropriate targeted subgroups remain the focus of intense research. During the last several years a number of new antithrombotic treatments have been introduced, and new data regarding established therapies have come to light. Although treatment guidelines include the most current available data, subsequent findings can be challenging to integrate. This challenge is compounded by the complexity associated with different efficacy and safety measures and the variability in study populations, presenting syndromes, physician, and patient preferences. In this work we review recent data regarding clinically available antiplatelet and anticoagulation agents used in the treatment of patients with ACS. We address issues including relative efficacy, safety, and timing of therapies with respect to conservative and invasive treatment strategies. In specific cases we will highlight remaining questions and controversies and ongoing trials, which will hopefully shed light in these areas. In addition to reviewing existing agents, we take a look forward at the most promising new antithrombotics currently in late-stage clinical development and their potential role in the context of ACS management.
