Non-ST Elevation MI: How Long Do We Have for A Coronary Angiography?

Non-ST Elevation MI: How Long Do We Have for A Coronary Angiography?

This summary discusses the early invasive strategy and the risk of mortality in non-ST-elevation AMI. Over the past 2 decades, mortality and complications rates have seen a significant reduction thanks to technological and pharmaceutical development, and the increasing experience of health teams. This is especially true when we look at the use of coronary angiography

One Year Prognosis of Atherosclerotic vs. Non-Atherosclerotic Lesions in MINOCA Patients

The use of intravascular imaging helps improve diagnosis in situations where a conventional coronary angiography might not be conclusive. That is the case of patients with myocardial infarction with non-obstructive coronary artery lesions (MINOCA). The largest MINOCA cohort reported so far has shown 5%-7% prevalence.  This pathology, initially considered benign, presents a remote mortality rate

Sex Differences According to Thrombus Burden in STEMI Patients

Many studies have shown there is higher mortality and complications among women after acute myocardial infarction (AMI) vs. men, especially after 30 days. Even though the mechanism driving higher mortality remains uncertain, recent studies have seen differences in thrombus formation with increased platelet count among women. In STEMI patients, intracoronary thrombus burden is a predictor

Coronary Artery Dissection and Cardiogenic Shock: How Do They Evolve?

Spontaneous coronary artery dissections (SCD) are more frequent in women and account for about 25% of all acute myocardial infarctions (AMI) before the age of 50. While the presence of cardiogenic shock due to AMI is infrequent, its evolution is still somewhat unclear and it has not been fully analyzed. Researchers conducted an analysis in

Post AMI Ventricular Septal Defect: Contemporary Results of Endovascular vs Surgical Repair

In the era of endovascular intervention, with shorter revascularization times, we see lower rates of mechanical complications due to acute myocardial infarction (AMI). Increased rates were recorded during the COVID-19 pandemic, but driven by delays in consultation.  Though occasional (with an estimated incidence of 0.2%), post AMI ventricular septal defect (VSD), or interventricular communication, involves

The Current Role of Thrombus Aspiration in Primary PCI

In general, thrombus aspiration in acute myocardial infarction (AMI) has not been shown beneficial by large studies. It could even be prejudicial, since it has been associated with stroke. However, there are certain scenarios where the presence of a significant number of these prevents us from reaching adequate TIMI flow 3, or is associated with

El ticagrelor muestra beneficios en la función microvascular coronaria luego de un IAMSEST

Ticagrelor Shows Benefits in Coronary Microvascular Function after NSTEMI

Coronary microvascular disfunction (CMD) is an important long-term prognosis predictor. CMD treatment can be an effective therapeutic strategy for patients with acute coronary syndrome (ACS). Nevertheless, more studies are needed to assess different strategies. In the PLATO (Study of Platelet Inhibition and Patient Outcomes) study, ticagrelor vs. clopidogrel reduced ischemic events and overall mortality in

OCT in STEMI Patients: Is It Safe to Prevent Stenting?

Percutaneous coronary intervention in patients with acute myocardial infarction (AMI) where the physiopathological mechanism is plaque erosion or non-atherosclerotic mechanisms (such as spontaneous coronary artery dissection) is not beneficial according to recent studies.  The EROSION study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence Tomography–Based Management in Plaque Erosion) has shown medical treatment with no

ACC 2022


Atherosclerosis plaque causing AMI is often large in volume, high in lipids and have a thin fibrous cap. Statins often reduce atherosclerosis progress, but the impact of PCSK 9 inhibitors (alirocumab) after acute coronary syndrome is scarcely known. The aim of this study was to determine the effect of alirocumab using intracoronary imaging (IVUS, OCT,
