Combined glycoprotein IIb/IIIa inhibitor therapy with ticagrelor for patients with acute coronary syndrome.

ABSTRACT: This study was to compare the efficacy and safety of combined glycoprotein IIb/IIIa inhibitor (GPI) and ticagrelor versus ticagrelor in patients with acute coronary syndrome (ACS). An observational study was conducted using the Improving Care for Cardiovascular Disease in China-ACS project. Totally, 13,264 patients with ACS and received combination therapy or ticagrelor therapy were analyzed. The primary outcome was the composite of major cardiovascular events (MACE: all-cause mortality, myocardial infarction [MI], stent thrombosis, cardiogenic shock, and ischemic stroke), and secondary outcomes included all-cause mortality, MI, stent thrombosis, cardiogenic shock, and ischemic stroke. The multivariable adjusted analysis indicated that combination therapy was associated with an increased risk of major cardiovascular events (MACE) (P = 0.001), any bleeding (P<0.001), and major bleeding (P = 0.005). Moreover, the multivariable adjusted for propensity score-matched (PSM) analysis suggested that combination therapy produced additional risk of MACE (P = 0.014), any bleeding (P<0.001), and major bleeding (P = 0.005). Moreover, PSM analysis suggested that combination therapy was associated with greater risk of stent thrombosis (P = 0.012) and intracranial bleeding (P = 0.020). Combined GPI and ticagrelor therapies did not have any beneficial effects on MACE, stent thrombosis, intracranial bleeding, any bleeding, or major bleeding.

Project description:BackgroundEarly studies of glycoprotein IIb/IIIa inhibitors (GPIs) demonstrated benefit during percutaneous coronary intervention for acute coronary syndromes (ACS). Since their introduction, the magnitude of benefit of GPIs has become unclear.HypothesisWe hypothesized that adding a GPI to unfractionated heparin in ACS patients treated with stents and thienopyridines is beneficial.MethodsWe searched the MEDLINE, Cochrane, and clinicaltrials.gov databases for randomized clinical trials that studied the use of GPIs during ACS. We required that patients be randomly assigned to unfractionated heparin plus a GPI versus unfractionated heparin plus placebo (or control). Additional inclusion criteria included the use of coronary stents and periprocedural thienopyridines. Outcomes were assessed at 30 days. Random effects DerSimonian-Laird summary risk ratios (RR) and 95% confidence intervals (CIs) were constructed.ResultsSixteen studies with 7611 patients were included. Myocardial infarction was 3.1% with GPI versus 4.4% with control (RR = 0.74; 95% CI, 0.59-0.94, P = 0.014); revascularization, 1.7% versus 2.7% (RR = 0.64; 95% CI, 0.46-0.89, P = 0.008); major bleeding, 2.5% versus 2.1% (RR = 1.21; 95% CI, 0.89-1.63, P = 0.22); minor bleeding, 5.5% versus 4.1% (RR = 1.37; 95% CI, 1.06-1.78, P = 0.016); and mortality, 2.2% versus 2.9% (RR = 0.79; 95% CI, 0.59-1.06, P = 0.12), respectively.ConclusionsAmong ACS patients treated with stents and thienopyridines, GPIs were associated with reduced myocardial infarction and revascularization. Minor, but not major bleeding was increased with GPIs. Mortality was similar between the groups. © 2011 Wiley Periodicals, Inc.

Project description:Ticagrelor is a novel P2Y?? receptor antagonist which, like clopidogrel and prasugrel, functions by blocking adenosine diphosphate-mediated platelet aggregation. However, unlike the aforementioned agents, the binding of ticagrelor to this receptor is reversible. Ticagrelor is also believed to mediate some of its beneficial effects by augmenting the effects of adenosine, which is another unique pharmacologic property of this drug. In terms of antiplatelet effect, ticagrelor is more potent than clopidogrel and produces a faster and stronger inhibition of platelet aggregation. This may also be an advantage of ticagrelor over prasugrel, but this has not been adequately studied. Due to the reversible nature of the binding of ticagrelor to the platelet receptor, ticagrelor has a relatively fast offset of effect, with platelet aggregation approaching pretreatment levels about 3 days after discontinuation of therapy. This has advantages in patients requiring invasive procedures, but also makes medication adherence very important in order to be able to maintain an effective antiplatelet effect. Ticagrelor has been shown to be clinically superior to clopidogrel when given to patients with an acute coronary syndrome, resulting in significantly lower rates of myocardial infarction and vascular death. However, ticagrelor is indicated to be administered with aspirin, and the clinical benefits of ticagrelor may be less when daily dosages of aspirin exceed 100 mg. As expected, bleeding is the most common adverse effect with ticagrelor, although it occurs at rates comparable with those seen for clopidogrel with the exception of noncoronary artery bypass graft-related major bleeding and fatal intracranial bleeds, the latter of which occurs only rarely. Dyspnea is another common adverse effect with ticagrelor, although this is usually not severe and resolves with drug discontinuation. Unlike clopidogrel, there are no known pharmacogenomic concerns with ticagrelor, and emerging data suggest ticagrelor to be effective in patients resistant to clopidogrel, although more study is needed on this topic. While preliminary data suggest ticagrelor to be cost effective when compared with generic clopidogrel, the acquisition cost of ticagrelor is not insignificant and this will likely be an issue for many health care organizations. Currently, ticagrelor is well positioned to assume an active role in the treatment of coronary artery disease due to an impressive efficacy profile and reasonable safety. Its ultimate role in therapy will continue to evolve as studies on this drug continue eg, (Prevention of Cardiovascular Events in Patients with Prior Heart Attack Using Ticagrelor Compared to Placebo on a Background of Aspirin, PEGASUS) and more information hopefully becomes available on its use in clopidogrel nonresponders and relative safety and efficacy compared with prasugrel.
