Ticagrelor reduces in-stent thrombosis in patients with acute coronary syndromes
Original title: Stent thrombosis with ticagrelor versus clopidogrel in patients with acute coronary syndromes: An analysis from the prospective randomized PLATO trial. Reference: Steg PG et al. Circulation. 2013; Epub ahead of print The PLATO study randomized 18624 patients with acute coronary syndrome to receive ticagrelor (180 mg loading dose followed by 90 mg twice daily )…
Ticagrelor similar to clopidogrel in terms of coronary flow and myocardial perfusion
Título original: Angiographic Outcomes in the PLATO Trial (Platelet Inhibition and Patient Outcomes). Referencia: Vijay Kunadian et al. J Am Coll Cardiol Intv 2013;6:671–83. In the PLATO (Platelet Inhibition and Patient Outcomes) trial, treatment with ticagrelor compared with clopidogrel resulted in a significant reduction in the combined endpoint of cardiac death, heart attack or stroke in patients undergoing…
Prasugrel is not as effective as Ticagrelor in acute myocardial infarction.
Original title: Comparison of Prasugrel and Ticagrelor loading doses in STEMI patients: The Rapid Activity of Platelet Inhibitor Drugs (RAPID) primary PCI Study. Reference: Guido Parodi et al. J Am Coll Cardiol 2013. Article in press. Current guidelines recommend the use of prasugrel or ticagrelor in patients with ST elevation acute coronary syndromes who are due to receive…
Serum fibrinogen is a better predictor of periprocedural events than platelet reactivity.
Original title: Elevated Plasma Fibrinogen Rather Than Residual Platelet Reactivity After Clopidogrel Pre-Treatment Is Associated With an Increased Ischemic Risk During Elective Percutaneous Coronary Intervention. Reference: Lawrence Ang et al. J Am Coll Cardiol 2013;61:23–34. Platelet function tests have identified differences in the response of each patient to clopidogrel and minor platelet inhibition has been associated with thrombotic…
Ticagrelor, even better than we thought
Original title: Reduction in First and Recurrent Cardiovascular Events with Ticagrelor Compared with Clopidogrel in the PLATO Study. Reference: Payal Kohli et al. CIRCULATION AHA.112.124248. In analyzing randomized and monitored study outcomes, we usually observe that after the occurrence of any primary outcome event patients are typically blocked for further analysis. This practice limits the information on subsequent…
Does the systematic use of clopidogrel reduce events prior to angioplasty?
Original title: Association of Clopidogrel Pretreatment with mortality, Cardiovascular events, and Major Bleeding among patients undergoing percutaneous coronary intervention. A systematic review and Mata-analysis. Reference: Anne Bellemain-Appaix, MD et al. for the ACTION group. The loading of clopidogrel before coronary angioplasty is an accepted practice by most clinical and interventional cardiologists but, nevertheless, it is only based on…
To discontinue clopidogrel after a year of infarction can be risky
Reference: Charlot et al. European Heart Journal 2012 (in press). International guideline recommendations approve giving dual antiplatelet therapy for a period of not less than 12 months after acute myocardial infarction. However, the benefit is unknown if the therapy is extended beyond 12 months. Perhaps its extension could be particularly useful in patients receiving pharmacological…
In patients with stroke history, Ticagrelor is superior to Clopidogrel
James SK, Storey RF, Khurmi N, et al. Ticagrelor versus Clopidogrel in Patients with Acute Coronary Syndromes and a History of Stroke or Transient Ischemic Attack. Circulation 2012. A sub-analysis of the PLATO study demonstrated similar superiority and the safety of ticagrelor in all patients, regardless of any previous history of stroke. Ticagrelor versus clopidogrel:…
Six Months Sufficient for Dual Antiplatelet Therapy

JACC Cardiovasc Interv 2011; 4: 1119-28.2011; 4: 1119-28. Patients treated with zotarolimus-eluting stents (ZES) suffer no excess late ischemic events if they take dual antiplatelet therapy for 6 months instead of 12 months or longer,…
Ticagrelor vs. Clopidogrel in ST elevation MI: Pros and cons
Platelet Inhibition in the PLATO study: insights from the ECG substudy. En el Estudio PLATO quedó evidenciado que el Ticagrelor disminuyó la mortalidad a 12 meses en comparación con el Clopidogrel en el tratamiento de pacientes post-angioplastía por un síndrome coronario agudo o por un cuadro estable (4,5 vs. 5,9%; P<0.001). Estos resultados fueron del…
