Managing periprocedural dual antiplatelet therapy (DAPT) in ACS patients is controversial and, to date, there are no randomized trials in this regard. Guidelines recommend ticagrelor discontinuation five days prior surgery and in the most emblematic work on this drug...
Diabetic patients are increased risk of thrombotic events, which is why an effective antiplatelet therapy is crucial for these patients. Both prasugrel and ticagrelor have shown to reduce thrombotic complications further than clopidogrel. Subgroup analyzes of the most important studies testing prasugrel and ticagrelor vs. clopidogrel have shown that diabetic patients receiving the new...
Much of the speculation around the way of individualizing dual antiplatelet therapy (DAPT) duration after coronary angioplasty has focused on clinical parameters (e. g., diabetes), but a new study published by the Journal of the American College of Cardiology (JACC) and presented at the last European Society of Cardiology (ESC) Congress warns about anatomical factors as...
A comprehensive analyzis of cerebrovascular events in major randomized controlled studies on transcatheter aortic valve replacement (TAVR) has shown some interesting data on both risks and timing of stroke in this setting. The study carried out by Dr. Neal Kleiman, reviewed data on stroke and stroke predictors among 3,687 patients included in the CoreValve...
This small study presented at ESC and simultaneously published in the European Heart Journal evaluated patients undergoing acute coronary syndrome caused by plaque erosion identified by optical computed tomography (OCT). The study showed it can be managed with conservative antithrombotic therapy and without stenting. Patients with plaque erosion can receive dual antiplatelet therapy, ticagrelor and aspirin...
Patients treated with A9 biolimus eluting stent with biodegradable polymer (Nobori, Terumo) can receive only six months of dual antiplatelet therapy (DAPT) with no increase in adverse events, compared against more prolonged treatments. The net adverse clinical and cerebrovascular events that included all cause death, MI, cerebrovascular events and major bleeding was: 1.92% for...
The largest randomized trial in history found no difference in the primary endpoint of death and nonfatal infarction between current conventional stents and drug-eluting stents at over 5 years in patients with stable or unstable coronary disease. As expected, NORSTENT did find a difference in revascularization rates between both groups. This study presented at the...
The choice of prasugrel or ticagrelor for patients with acute myocardial infarction undergoing primary angioplasty makes no difference, at least in the short term. This study was terminated prematurely and thus lost statistical power, which means that any interpretation of the lack of difference between the two antiplatelet drugs must take into account such...
This study, presented in Rome at the European Society of Cardiology Congress 2016 and published simultaneously online in the Journal of the American College of Cardiology (JACC), has identified a post-TAVI valve thrombosis rate of 7% using multidetector computerized tomography (CT). However, the vast majority of cases were completely asymptomatic. Previous studies had shown...
Ticagrelor might be a more effective antiplatelet therapy than aspirin for the prevention of recurrent stroke and cardiovascular events in patients admitted for acute cerebral ischemia. This double-blind, controlled trial randomized 13,199 patients from 33 countries. Subjects presented a non-severe stroke or a high-risk transient ischemic attack (TIA) (not considered as cardioembolic) and had not received...
