Acute myocardial infarction (AMI) can be caused by a ruptured plaque with sudden thrombosis occlusion or an embolization formation. Previous investigations have described the use of thrombolytic therapy, balloon angioplasty plus stenting, and various mechanical thrombectomy devices to treat patients with AMI with intracoronary thrombus, but all of these methods have certain limitations. The authors report 2 cases of AMI, 1 caused by ruptured plaque and the other caused by embolization, with large thrombus formation and total occlusion of the infarct-related artery. Manual thrombosuction with the Export catheter proved effective and safe for treating these 2 patients and achieved final thrombolysis in myocardial infarction (TIMI) III flow with good myocardial brushing.

Restrictive Versus Liberal Transfusion in Symptomatic Coronary Artery Disease and Myocardial Infarction: A Meta-Analysis of Randomized Controlled Trials.

Division of Cardiology, Ellis Hospital, New York, NY.
Background: In patients with coronary artery disease (CAD) and/or myocardial infarction (MI), anemia is associated with an increased risk of adverse cardiovascular (CV) outcomes. Transfusion goals in such patients remain unclear.
Study Question: A meta-analysis of the available randomized controlled trials (RCTs) was conducted comparing restrictive and liberal transfusion strategies in patients with symptomatic CAD/MI.

Coronary artery disease (CAD) is the leading cause of death worldwide. Acute coronary syndrome (ACS) encompasses a spectrum of diagnoses ranging from unstable angina pectoris to myocardial infarction with and without ST-segment elevation and frequently presents as the first clinical manifestation. It is crucial in this scenario to perform a timely and comprehensive assessment of patients by evaluating the clinical presentation, electrocardiogram and laboratory diagnostics using highly sensitivity cardiac troponin in order to initiate a timely and risk-adapted continuing treatment with immediate or early invasive coronary angiography.

Department of Cardiovascular & Thoracic Surgery, Sandra Atlas Bass Heart Hospital at North Shore University Hospital, Northwell Health, 300 Community Drive, 1 DSU, Manhasset, NY, 11030, USA.
Purpose Of Review: This article discusses a tailored approach to managing cardiogenic shock and temporary mechanical circulatory support (tMCS). We also outline specific mobilization strategies for patients with different tMCS devices and configurations, which can be enabled by this tailored approach to cardiogenic shock management.
Recent Findings: Safe and effective mobilization of patients with cardiogenic shock receiving tMCS can be accomplished.
Potassium Current Signature of Neuronal/Glial Progenitors in Amniotic Fluid Stem Cells.

January 2025
Department of Chemistry, Biology and Biotechnologies, University of Perugia, Via dell'Elce di Sotto 8, 06123 Perugia, Italy.
Article Synopsis
- Amniotic fluid contains stem cells (AF-SCs) that have potential uses in regenerative medicine for treating various injuries and diseases.
- When exposed to basic Fibroblast Growth Factor (bFGF), AF-SCs show the ability to survive and migrate in a rat brain model, resembling characteristics of neuronal/glial progenitor cells.
- The study employs electrophysiological techniques to identify specific potassium currents in AF-SCs and confirms that histamine can influence calcium dynamics and potassium current activation in these cells.

Cardiogenic shock represents a critical condition in which the heart is unable to maintain adequate circulation leading to insufficient tissue perfusion and end-organ failure. Temporary mechanical circulatory support offers the potential to stabilize patients, provide a bridge-to-recovery, provide a bridge-to-decision, or facilitate definitive heart replacement therapies. Although randomized controlled trials have been performed in infarct-related cardiogenic shock and refractory cardiac arrest, the optimal timing, appropriate patient selection, and optimal implementation of these devices remain complex and predominantly based on observational data and expert consensus, especially in non-ischaemic shock.
