The LEADERS FREE study showed that a biolimus A9-coated polymer-free stent was superior to a conventional stent in terms of safety and efficacy in patients who received dual antiplatelet therapy for only a month due to their high risk for bleeding. In this substudy, researchers analyzed 667 patients enrolled in the original LEADERS FREE trial who met certain requirements…
ACC 2018 | TREAT: Ticagrelor + Fibrinolytics’ Effect on Bleeding
Ticagrelor seems as safe as clopidogrel in patients undergoing ST elevation MI treated with fibrinolytics, at least in terms of TIMI major bleeding at 30 days. Longer follow up will help determine whether there are differences in efficacy or safety issues, as stated by the presenter Otavio Berwanger. This study was presented at ACC 2018 scientific sessions…
Dual Antiplatelet Therapy: Less Is More for Elderly Patients
A recent meta-analysis that will be published soon in JACC Intv offers evidence of benefit derived from short-term dual antiplatelet therapy for elderly patients. This is a patient group that has always been excluded from the major trials, while remaining one of the most challenging subgroups in which to balance bleeding and ischemic risks. The…
Transulnar Access: Another Ace Up Our Sleeve Before Transfemoral Access
Transulnar access can be as safe and effective as transradial access, and it is a particularly good alternative for the preservation of radial artery patency or when such vessel presents a difficult anatomy. This new meta-analysis that will be published soon in Catheter Cardiovasc Interv showed a relatively high failure rate for that access, but…
Ischemic and Bleeding Risk After Primary Angioplasty
Patients with ST-segment elevation myocardial infarction who undergo primary angioplasty are at high risk for both ischemic and bleeding events, which affect significantly both morbidity and mortality. An optimal selection of antithrombotic therapies in terms of strength and duration must take into account the timing for the procedure, since the risk for these complications may…
NCDR ACTION Registry: Anticoagulated Patients with No Higher Risk of Bleeding in Emergency Procedures
Patients with a history of atrial fibrillation treated with warfarin or any of the new direct oral anticoagulants undergoing acute myocardial infarction do not present higher risk of bleeding when receiving angiography or angioplasty. In fact, this subgroup of anticoagulated patients showed lower in-hospital mortality than the control group. After analyzing 6471 patients undergoing ST elevation MI…
Polymer-Free DES Also Show Efficacy in Anticoagulated Patients with High Risk for Bleeding
Patients who receive chronic anticoagulation therapy and then undergo angioplasty are frequently discharged on a triple anti-thrombotic scheme that usually includes aspirin, clopidogrel, and warfarin. The optimal duration of this indication remains unclear, particularly for patients at high bleeding risk. According to expert consensus, patients receiving chronic anticoagulation may receive from 1 to 12 months of dual…
VALIDATE-SWEDEHEART: bivalirudin seems to be losing ground
Another important work that does not see the benefits of bivalirudin over heparin as monotherapy as regards both efficacy (death and MI) and safety end points (bleeding) in patients undergoing acute myocardial infarction with and without ST elevation. The study VALIDATE-SWEDEHEART, presented at ESC, simultaneously published in the New England Journal of Medicine, randomized 6000 patients…
Dual antiplatelet therapy discontinuation causes more thrombotic events at 12 months
Several randomized studies have shown that dual antiplatelet therapy (DAPT) is as effective to prevent thrombotic events in the segment treated with PCI, as it is with the rest of the coronary segments. This is very clear. The problem is there are a series of adverse events following P2Y12 inhibitor discontinuation. This phenomenon called rebound effect, happens…
Bleeding and Mortality in Transcatheter Aortic Valve Replacement
Transcatheter aortic valve replacement (TAVR) is much less invasive than surgical replacement. This is associated with a substantial reduction in bleeding events (up to 60% less). However, clinically relevant bleeding is still present in one every four patients who undergo TAVR, which is associated with morbidity and mortality. Cases of bleeding are not uniform: they may…
