Arch Iran Med 2021 Nov 1;24(11):796-803. Epub 2021 Nov 1.

Cardiovascular Research Center, Health Institute, Imam-Ali hospital, Kermanshah University of Medical Sciences, Kermanshah, Iran.

Background: Considerable variability in survival rate after ST-segment elevation myocardial infarction (STEMI) is present and outcomes remain suboptimal, especially in low- and middle-income contraries. This study aimed to investigate predictors of 30- day mortality after STEMI, including reperfusion therapy, in a tertiary hospital in western Iran.

Methods: In this registry-based cohort study (2016-2019), we investigated reperfusion therapies - primary percutaneous coronary intervention (PPCI), pharmaco-invasive (thrombolysis followed by angiography/percutaneous coronary intervention), and thrombolysis alone - used in Imam-Ali hospital, the only hospital with a PPCI capability in the Kermanshah Province.

The Spiked Helmet Sign Predicting a Poor Outcome in a Patient with Non-Myocardial Infarction ST-Segment Elevation.

Medicina (Kaunas) 2021 Nov 1;57(11). Epub 2021 Nov 1.

Department of Emergency Medicine, Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, New Taipei 231, Taiwan.

Spiked helmet sign is a novel electrocardiogram marker that reflects a poor prognosis, and may mimic myocardial infarction, especially in patients with an acute alteration of mental status or out-of-hospital cardiac arrest. In cases where a spiked helmet sign is missed, there may be a delay in surgical intervention for the underlying conditions because of unnecessary cardiac catheterization. In addition, antiplatelet agents for acute coronary syndrome in such cases can lead to catastrophic complications. Read More

Department of Emergency Medicine, University of Ulsan College of Medicine, Asan Medical Center, Seoul 05505, Korea.

It is challenging to rule out acute coronary syndrome among chest pain patients without both ST-segment elevation in electrocardiography and troponin elevation at emergency departments (ED). The purpose of this study was to develop a prediction model for rapidly determining the occurrence of significant stenosis in coronary computed tomography angiography (CCTA). Retrospective observational cohort study was conducted with 904 patients who had presented with chest pain without troponin elevation and ST-segment changes and underwent CCTA between January 2017 and December 2018.

Predictive Value of Cardiac Magnetic Resonance Feature Tracking after Acute Myocardial Infarction: A Comparison with Dobutamine Stress Echocardiography.

J Clin Med 2021 Nov 12;10(22). Epub 2021 Nov 12.

Cardiology Department, Hospital Universitari Vall d'Hebron, 08035 Barcelona, Spain.

In acute ST-segment elevation myocardial infarction (STEMI) late gadolinium enhancement (LGE) may underestimate segmental functional recovery. We evaluated the predictive value of cardiac magnetic resonance (CMR) feature-tracking (FT) for functional recovery and whether it incremented the value of LGE compared to low-dose dobutamine stress echocardiography (LDDSE) and speckle-tracking echocardiography (STE). Eighty patients underwent LDDSE and CMR within 5-7 days after STEMI and segmental functional recovery was defined as improvement in wall-motion at 6-months CMR. Read More

Sudden cardiac arrest during the immediate revascularization period in patients with non-ST elevation myocardial infarction: A case series.

Cardiovasc Revasc Med 2021 Nov 20. Epub 2021 Nov 20.

Department of Internal Medicine, Morehouse School of Medicine, Atlanta, GA, USA; Division of Pulmonary and Critical Care Medicine, Morehouse School of Medicine, Atlanta, GA, USA.

Introduction: The timing of sudden cardiac arrest (SCA) after myocardial infarction (MI) has been a subject of research because of the impact on preventive strategies. Currently, there is limited data on the risk of SCA in the immediate post revascularization period (≤48 h) in non-ST segment elevation myocardial infarction (NSTEMI).

Gene regulatory network analysis identifies key genes and regulatory mechanisms involved in acute myocardial infarction using bulk and single cell RNA-seq data.

Math Biosci Eng 2021 Sep;18(6):7774-7789

School of Mathematics, Sun Yat-sen University, Guangzhou 510275, China.

Cardiovascular and cerebrovascular diseases are leading causes of death worldwide, accounting for more than 40% of all deaths in China. Acute myocardial infarction (AMI) is a common cardiovascular disease and traditionally divided into ST-segment (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI), which are known with different prognoses and treatment strategies. However, key regulatory genes and pathways involved in AMI that may be used as potential biomarker for prognosis are unknown. Read More

Acute Myocardial Infarction in a Patient with Twin Pregnancy: A Case Report.

Clin Pract Cases Emerg Med 2021 Nov;5(4):507-510

Henry Ford Wyandotte Hospital, Department of Medicine/Division of Cardiology, Wyandotte, Michigan.

Introduction: Acute myocardial infarction (AMI) rarely occurs during pregnancy and presents unique challenges in diagnosis and management. Traditionally, pregnancy has not readily been considered a risk factor for AMI in the emergency department despite the potential for adverse impacts on maternal and fetal health. As cardiovascular risk factors and advanced maternal age become more prevalent in society over time, the incidence will continue to increase. Read More

Glob Cardiol Sci Pract 2021 Oct 30;2021(3):e202123. Epub 2021 Oct 30.

Division of Cardiovascular Medicine, Department of Medicine, University of Louisville School of Medicine, Louisville, Kentucky 40202, USA.

Coronary air embolism is a rare iatrogenic complication during invasive coronary angiography or angioplasty that can cause acute chest pain, hypotension, ST-segment elevation myocardial infarction, and even death. We present a case of left anterior descending coronary artery air embolization in a 58-year-old heart transplant patient that occurred during cardiac allograft vasculopathy surveillance angiography.

Successful off-label use of rotational atherectomy in ST-segment elevation myocardial infarction: A case report.

Cardiovasc Revasc Med 2021 Nov 14. Epub 2021 Nov 14.

First Cardiology Department, AHEPA University Hospital, Aristotle University of Thessaloniki, Thessaloniki, Greece.

Rotational atherectomy (RA) in ST-segment elevation myocardial infarction (STEMI) is uncommon and its use in a thrombotic lesion is labelled a contraindication by its manufacturer due to the concern for further increase in platelet activation and aggregation by the spinning burr or distal embolization of the thrombotic material promoting no-reflow (NR). However, thrombus burden varies significantly in the STEMI setting and can be classified according to the thrombolysis in myocardial infarction (TIMI) thrombus grade (TG). This case demonstrates the successful off-label use of RA-assisted primary percutaneous coronary intervention to facilitate treatment of a heavily calcified ostial right coronary artery lesion with low thrombotic burden (TIMI TG 0) in an octogenarian STEMI patient.
