Antiplatelet therapy is key to prevent thrombotic events after a transient ischemic attack (TIA) or ischemic stroke. The role of aspirin is well established in this scenario, but there is emerging evidence for a short period of dual antiplatelet therapy (DAPT). Now, can this strategy avoid recurrent strokes without paying a price in terms of…
How to Discontinue Antiplatelet Therapy Prior Non-Cardiac Surgery
Both the indication and discontinuation of antiplatelet therapy to balance ischemic-bleeding risks has been left to physician criterion. However, leaving the decision to one single specialist might not be the best. This is when the team’s role becomes essential. This study looked at the advantages consensus decision-making amongst clinicians, surgeons and anesthesiologists to continue or…
Back to Basics: Ticagrelor Questioned and Clopidogrel in the Limelight
Yet another observational study has come to question the antiaggregation power of ticagrelor when it comes to death or MI reduction, pointing at its higher risk of bleeding vs. clopidogrel. This new analysis recently published in JAHA includes a large number of patients undergoing acute coronary syndrome (ACS) in the clinical practice. Ticagrelor has been…
Xience Receives CE Mark for Short and Ultrashort DAPT Schemes
Dual antiplatelet therapy (DAPT) one month after angioplasty with Xience stent was approved in Europe for patients with high risk of bleeding. The CE Mark approval comes after studies Xience 28 and Xience 90 are published. Immediately after authorization, Abbot was fast to announce what they consider to be the shortest approved scheme with the most…
Dual Antiplatelet Therapy and TAVR: Obsolete Guidelines
The current guidelines recommend dual antiplatelet therapy (DAPT) 3 to 6 months after transcatheter aortic valve replacement (TAVI). Some recent data finally condensed in the present meta-analysis and recently published in JAHA happen to challenge these guidelines. Clinical studies that investigated single antiplatelet therapy versus DAPT until November 2020 were analyzed and divided according to…
Short Therapy and Monotherapy, Plenty of Evidence
A short dual antiplatelet therapy (DAPT) of 1 to 3 months followed by P2Y12 inhibitor monotherapy after second generation drug eluting stent (DES) implantation is safer and as effective as the traditional scheme. The idea is clear, but why hasn’t aspirin monotherapy been tested as follow up? Is aspirin old fashioned? Are there physiopathological reasons…
Net Clinical Benefit of Long-Term Ticagrelor
Ticagrelor reduces ischemic risk in patients with a history of acute myocardial infarction, but it increases the risk of bleeding. Keeping a delicate balance is paramount when prescribing long-term ticagrelor to patients with a history of infarction. The PEGASUS-TIMI 54 study randomized 21,162 patients with a history of infarction on a 1:1:1 ratio: some received ticagrelor…
Ticagrelor: Yet Another Pleiotropic Effect?
Studies in animals have shown ticagrelor offers better myocardial protection against reperfusion injury after ST elevation MI than clopidogrel. This had to be tested in the clinical arena, which is the aim of this study (published in JACC Intv): to assess left ventricular remodeling after reperfusion. The study included patients undergoing their first ST elevation…
Should We Discontinue Anticoagulation Before TAVR?
Against what common sense dictates, continuing oral anticoagulation pre- and post- transcatheter aortic valve replacement (TAVR) is safe, according to this article soon to be published in JACC Interventions. There was no increase in hemorrhagic or vascular complications and, paradoxically, those who continued using anticoagulant agents received fewer transfusions that those who did not. A…
More Evidence for Short Term DAPT: Approaching “the Class Effect”
Patients at high risk of bleeding undergoing coronary angioplasty with Orsiro stent can be considered for a short dual antiplatelet scheme. These data come from the SMART-CHOICE study recently published in JAHA, adding the Orsiro stent to the list of devices supporting 3-month DAPT. This study included 2993 patients undergoing coronary angioplasty randomized to 3…
Diabetes and Peripheral Vascular Disease: Old Drugs, New Evidence
This paper, recently published in JAHA, showed that patients with type 2 diabetes mellitus exhibiting lower-limb vascular disease benefit from combining cilostazol and clopidogrel. Treatment for at least 6 months with clopidogrel (75 mg/QD) plus cilostazol (100 mg/BID) significantly reduces ischemic events—including stroke, infarction, and death from vascular causes—compared with clopidogrel monotherapy. Adding cilostazol reduces ischemic events, but that…
