Most clinical trials have shown benefits of beta blockers after acute myocardial infraction, including patients with extensive AMI, and these were carried out in the era before AMI was diagnosed with biomarkers and prior to treatment with coronary angioplasty, use of antithrombotic agents and high intensity statins, and angiotensin-aldosterone system inhibitors. The aim of this...
The aim of this study was to assess hard end points such as death or MI in patients with acute coronary syndrome (ACS) presenting hemoglobin levels lower than 10 mg/dl. It was a randomized multicenter double blind trial including 3506 participants. The study looked at different transfusion strategies, comparing restrictive strategy with 7-8 g/dl hemoglobin...
Patients over 75 with acute coronary syndrome (ACS) are often badly represented in most significant studies. In this context, the FIRE study looked to determine whether physiology guided complete revascularization is superior to culprit-only revascularization in elderly patients with multivessel disease suffering acute MI. The study included SCA patients over 75, hospitalized for both STEMI...
Dual antiplatelet therapy (DAPT) is the current standard for preventing thrombotic events in high-risk patients with coronary artery disease, as well as in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). However, this approach increases the risk of bleeding. To reduce this risk, there have been studies that discontinued the use of...
Abbreviated dual antiplatelet therapy in patients at high risk for bleeding and acute myocardial infarction. Patients with acute coronary syndrome (ACS) who undergo stent placement (percutaneous coronary intervention, PCI) conventionally require at least 12 months of dual antiplatelet therapy (DAPT) to reduce ischemic events. Patients with ACS who are also at high risk for bleeding...
Event predictors in patients with plaque erosion and no stenting. A third of all acute coronary syndrome (ACS) cases are caused by plaque erosion. In the initial EROSION study, it was shown that patients with plaque erosion (as evidenced by OCT, with stenosis <70%, TIMI III flow, and asymptomatic) were stabilized without stent implantation (no...
The incidence of left ventricular thrombosis (LVT) after anterior ST-segment elevation myocardial infarction (STEMI) ranges from 4% to 26%. This is associated with bad long-term evolution. In the past, triple-scheme therapy (vitamin K antagonist plus dual antiplatelet therapy) was recommended to prevent LVT, despite the lack of high-quality scientific evidence and an increase in the...
The Latin American Society of Interventional Cardiology together with the Interamerican Society of Cardiology (SIAC) and the Stent-Save a Life! Initiative have developed a short survey (which can be answered in less than 5 minutes) to learn how ST-segment elevation acute coronary syndromes are treated in Latin America. The final objective of this survey is...
The use of intravascular ultrasound (IVUS) has seen exponential growth across registries over the years, combined with mounting and increasingly robust evidence. The fact that it will enable us to characterize plaque morphology and extension prior the intervention, and even assess stent expansion post intervention, has turned it into a pillar of our efforts to...
Suspending ticagrelor a couple of days before surgery was non-inferior to waiting 5-6 days in terms of bleeding in patients with acute coronary syndrome (ACS) requiring myocardial revascularization surgery. Patients who waited longer had more ischemic events and longer hospitalizations. Current American guidelines recommend waiting at least 5 days before operating on patients with ACS who...
