Most acute coronary syndromes (ACS) are caused by the following three different pathologies: Plaque rupture Plaque erosion Calcified nodule In daily clinical practice, all patients who experience them are treated with angioplasty, regardless of which of these physiopathologies led to the ACS in each case. Some early reports indicate that patients with plaque erosion might...
Patients undergoing primary angioplasty for ST-segment elevation acute myocardial infarction have similar clinical outcomes at 1 year regardless of whether they are treated with ticagrelor or prasugrel, according the PRAGUE-18 study. This new substudy adds an interesting detail: patients who switched from prasugrel and ticagrelor to clopidogrel, citing economic reasons for the “de-escalation” of therapy, were...
Dual antiplatelet therapy with aspirin and a P2Y12 inhibitor is the treatment of choice for patients with acute coronary syndrome who undergo coronary angioplasty. Different oral P2Y12 inhibitors (clopidogrel, prasugrel, ticagrelor) present different characteristics as regards efficacy, risk for bleeding, cost, and timing of administration. In this sense, physicians frequently switch among drugs according to...
The discussion about the best anti-thrombotic strategy for patients with atrial fibrillation undergoing PCI seemed never-ending until the RE-DUAL PCI trial was published in the New England Journal of Medicine (NEJM). This study has arrived to simplify the tough choice between the risk of a thrombotic event vs. the risk of bleeding with a simpler scheme, without...
Fentanyl is a potent opiate commonly administered in the cath lab. Recently, questions on its safety have been raised by research demonstrating that intravenous morphine significantly delays the absorption of oral P2Y12 platelet inhibitors. The mechanism might be slowed gastric emptying. The Platelet Aggregation with tiCagrelor Inhibition and FentanYl (PACIFY) trial enrolled 212 patients undergoing indicated...
RE-DUAL PCI outcomes have been published by the New England Journal of Medicine along with their presentation at ESC 2017. The traditional triple anti-thrombotic scheme with dual antiplatelet therapy and warfarin for patients with atrial fibrillation undergoing coronary angioplasty seems to have been left behind. This new study showed that the combination of dabigatran with a P2Y12...
Courtesy of Dr. Gustavo Leiva. Coronary Artery Bypass Graft (CABG) has traditionally been the procedure of choice in patients with left main coronary artery disease. However, the use of percutaneous techniques in this kind of lesions has been on the rise, partly due to recent research showing similar outcomes with both procedures. Unprotected left main...
Newer P2Y12 blockers are the front-line treatment and dual antiplatelet therapy is indicated for 1 year after acute coronary syndrome (ACS). Both prasugrel and ticagrelor offer more ischemic benefit than clopidogrel during the initial phase; however, bleeding complications could increase in the long term. The objective of this study was to assess the safety and efficacy...
Courtesy of Dr. Agustín Vecchia. In treating bifurcations, the provisional stenting strategy continues to be preferred. However, a percentage of these lesions must be treated with two stents, which involves different techniques. In provisional stenting, when two stents are required, a recent consensus document of the European Bifurcation Club has recently recommended the TAP...
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...
