Pretreating non-ST elevation acute myocardial infarction (NSTEMI) patients with P2Y12 receptor inhibitors is not associated with improved clinical outcomes as it is to increased bleeding. NSTEMI patients are often treated with platelet antiaggregants in the daily clinical practice despite the lack of evidence for its benefits. This Swedish registry prospectively included 64857 patients undergoing NSTEMI...
Invasive functional measurement of intermediate lesions has become the gold standard to define revascularization. Due to its favorable long-term prognostic value, fractional flow reserve (FFR) is the reference used to compare all others. Recently, new nonhyperemic indexes, measured in a specific diastolic period, have emerged. Among them, the one with the most accumulated evidence is...
Ticagrelor monotherapy after 3 months of dual antiplatelet therapy in patients who experienced ST-segment elevation infarction significantly reduces major bleeding without increasing ischemic risk. This pre-specified analysis of the TICO study shows that ticagrelor monotherapy is safe even in patients with higher ischemic risk. Interrupting aspirin use after 3 months of dual antiplatelet therapy and continuing treatment...
Cerebral protection device TriGUARD 3, designed to cover all supra-aortic vessels during transcatheter aortic valve replacement (TAVR), is safe to use, according to the outcomes of the REFLECT II study. The technical feasibility of the device, which requires transfemoral access, does not seem to have an impact over clinical events. The primary safety endpoint was a VARC-2-defined...
Following with aspirin alone after a short period of dual antiaggregation therapy (DAPT), 1 to 3 months, did not increase ischemic events in patients receiving a Xience stent while significantly reducing bleeding. This study endorses the safety of short DAPT with contemporary drug eluting stents (DES) in patients presenting high bleeding risk. The XIENCE Short...
The self-expanding Acurate Neo (Boston Scientific) did not meet non-inferiority vs. the self-expanding CoreValve Evolut (Medtronic) in the SCOPE 2 study published in Circulation simultaneously and presented at the virtual TCT 2020. These are bad news for the Acurate Neo, that had already failed to show non-inferiority vs. the Sapien 3 in the SCOPE 1...
Optical coherence tomography (OCT) has proven useful in diabetic patients, even those with negative FFR. These findings make us rethink the ischemia and functional revascularization paradigm vs. the anatomical findings of vulnerable plaque. Diabetic patients with lesions that might be deferred base don FFR might benefit from OCT to find in these plaques certain risk...
Non-invasive coronary vasospasm diagnosis by means of echocardiography with the administration of ergonovine can be performed safely; even without prior angiography to rule out fixed lesions. These data are encouraging and move patients with vessel spasm but without significant lesions away from multiple angiographies and from the uncertainty of a diagnosis “by exclusion.” This work...
Ticagrelor compared against clopidogrel produces more bleeding and also more deaths in patients over 80 recently undergoing acute myocardial infarction. Contrary to what has been observed in the general population, these data from the SWEDEHEART registry of post MI patients over 80, show higher bleeding and mortality rates with ticagrelor compared against clopidogrel. These findings...
Aspirin discontinuation 1 to 3 months after angioplasty with continued P2Y12 inhibitor therapy reduces the bleeding risk without an increase in thrombotic events. This is also the case for patients admitted with acute coronary syndrome. Dual antiplatelet therapy with aspirin and a P2Y12 inhibitor has been shown to reduce the risk of major events compared with...
