D for getting clopidogrel (75 mg/day, with a loading dose of 300 to 600 mg) or HSP40 list ticagrelor (90 mg twice everyday, using a 180 mg loading dose). The key combined endpoint (mortality as a consequence of vascular cause, AMI or stroke) in 12 months was substantially smaller in the ticagrelor group (9.8 vs 11.7 ). No considerable distinction was verified on significant bleeding rates when the study’s major bleeding price was utilised. On the other hand, when TIMI’s key bleeding criteria have been employed, the bleeding price was larger in patients not submitted to myocardial bypass within the ticagrelor group (two.eight vs two.two ; p = 0.03).The isolated evaluation of AMI, vascular mortality and all-cause mortality rates showed a statistically considerable rate in patients taking ticagrelor. Within this study, the key adverse effects have been dyspnea and bradycardia13.Arq Bras Cardiol. 2013;101(three):277-Falc et al. P2Y12 platelet receptorsReview ArticleOne attainable hypothesis for explaining the mortality reduction obtained with ticagrelor is the fact that this drug has other effects besides antiplatelet action. Ticagrelor inhibits adenosine reuptake by red blood cells and is structurally connected to adenosine, CYP1 Compound suggesting that the latter may well be certainly one of its metabolites. Adenosine has cytoprotective, anti-inflammatory, antifibrotic and cardioprotective properties, which could explain ticagrelor benefits. Adenosine can also justify the primary adverse effects of this drug, which include dyspnea and ventricular pauses. A lot more proof is needed, even though, for confirming the direct association of ticagrelor and adenosine30,31. As a consequence of its quick half-life, platelet reactivity returns to basal levels immediately after three to four missing doses. That is essential for sufferers requiring surgical intervention. Nevertheless, poor drug adherence rapidly exposes the patient towards the threat of ischemic events. Prasugrel vs. Ticagrelor You will discover no studies comparing these drugs clinically; therefore, care should be taken when extrapolating information from diverse papers. The study TRITON randomized the great majority of its individuals (99 ) with knowledge of their coronary anatomy, while PLATO, around the other side, randomized sufferers at the emergency room. The clopidogrel dose permitted inside the two research was also different. About 50 on the sufferers within the PLATO study and 33 of your TRITON study individuals have been taking proton pump inhibitors. A final diagnosis of ACS with ST elevation was created in 37 of the sufferers within the PLATO study and 26 of your individuals in the TRITON study. In PLATO, with the exception of sufferers submitted to thrombolysis, all therapeutic regimens were evaluated (interventionist, surgical and clinical), while in TRITON sufferers were randomized right after intervention was indicated12,13. Thus, the two studies have unique populations and styles, and it is not achievable to examine the drugs. Biondi-Zoccai et al evaluated both drugs in an indirect metanalysis and demonstrated the advantage of prasugrel with regards to stent thrombosis and ticagrelor relating to big bleeding related to surgical bypass. No difference was observed regarding mortality, AMI or stroke32.bleeding complications per se cause a worse prognosis34. In the group of patients with chronic renal dysfunction, by way of example, dual platelet antiaggregation therapy greatly increases hemorrhagic events, lowering or perhaps overriding PCI advantage on a medium term basis35. The bleeding threat is usually evaluated by clinical prediction scores such as CRUSADE, but these scores don’t have very good prediction values, limiting.
