STEMI EKG

BACKGROUND: Coronary arteritis leading to aneurysm is one of the unusual presentations of IgG4-related disease. Acute myocardial infarction as a complication of IgG4-related giant coronary artery aneurysm is even rarer. CASE SUMMARY: We describe the case of a 56-year-old gentleman who presented to our institute with Canadian Cardiovascular Society (CCS) class III angina. His symptoms were persistent even with high-dose antianginal medications. He had an acute coronary syndrome two weeks back for which he was treated conservatively in a peripheral health centre...

OBJECTIVES: To investigate the mechanism of electroacupuncture (EA) at "Neiguan" (PC6) in impro-ving myocardial electrical remodeling in rats with acute myocardial infarction (AMI) by enhancing transient outward potassium current. METHODS: A total of 30 male SD rats were randomly divided into control, model and EA groups, with 10 rats in each group. The AMI model was established by subcutaneous injection with isoprenaline (ISO, 85 mg/kg). EA was applied to left PC6 for 20 min, once daily for 5 days...

BACKGROUND: Kounis syndrome is an acute coronary syndrome (ACS) caused by allergic reactions, including coronary artery spasm (type I) caused by allergies without coronary predisposing factors, pre-existing coronary atherosclerosis, and coronary artery disease. Anaphylaxis leads to plaque rupture or erosion leading to acute myocardial infarction (type II) and acute coronary stent thrombosis (type III). Here we share a case of Kounis syndrome type I caused by an allergy caused by a Cryptopteran bite...

PURPOSE: Prehospital telecardiology facilitates early ST-elevation myocardial infarction (STEMI) detection, yet its widespread implementation remains challenging. Extracting digital STEMI biomarkers from printed electrocardiograms (ECGs) using phone cameras could offer an affordable and scalable solution. This study assessed the feasibility of this approach with real-world prehospital ECGs. MATERIALS AND METHODS: Patients suspected of having STEMI by emergency medical technicians (EMTs) were identified from a policy research dataset...

The electrocardiogram is universally used to diagnose ST-segment elevation myocardial infarction and serves as guidance for the interventional cardiologist to identify the acute thrombotic lesion. However, this case illustrates that the electrocardiogram can also be deceiving.

BACKGROUND: Takotsubo cardiomyopathy (TC) is an emergency cardiovascular disease, with clinical and paraclinical manifestations similar to acute myocardial infarction (AMI), but it is characterized by reversible systolic dysfunction of the left ventricle (LV) in the absence (most of the time) of obstructive coronary artery disease (CAD). MANAGEMENT OF PATIENTS WITH TC: TC seems to be more frequent in post-menopausal women and it is triggered by emotional or physical stress...

The 12-lead electrocardiogram (ECG) is an integral component to the diagnosis of a multitude of cardiovascular conditions. It is performed using a complex set of skin surface electrodes, limiting its use outside traditional clinical settings. We developed an artificial intelligence algorithm, trained over 600,000 clinically acquired ECGs, to explore whether fewer leads as input are sufficient to reconstruct a full 12-lead ECG. Two limb leads (I and II) and one precordial lead (V3) were required to generate a reconstructed synthetic 12-lead ECG highly correlated with the original ECG...

A 70-year-old Japanese woman with hypertension, dyslipidemia, and diabetes mellitus complained of abdominal discomfort and vomiting and was brought to our emergency department by ambulance two days later with impaired consciousness. Her vital signs suggested shock with a heart rate of 120 bpm. Electrocardiogram and initial transthoracic echocardiography suggested an inferior wall ST-elevation myocardial infarction, but the altered consciousness was inconsistent. Contrast-enhanced computed tomography was urgently performed to further clarify the cause...

BACKGROUND: Acute myocardial infarction (MI) is a major cause of cardiovascular mortality, which is the leading cause of death in the world. Our objective in this study was to evaluate the epidemiological, clinical, and angiographic features of right ventricular infarction (RVI), as well as its complications and its therapeutic approaches. PATIENTS AND METHODS: It is a single-centered retrospective descriptive study conducted over a period of 2 years from November 2018 to October 2020...

BACKGROUND: The HEART Pathway (History, Electrocardiogram, Age, Risk factors, Troponin) can be used with high-sensitivity cardiac troponin to risk stratify emergency department patients with possible acute coronary syndrome. However, data on whether a high-sensitivity HEART Pathway (hs-HP) are safe and effective is lacking. METHODS: An interrupted time series study was conducted at 5 North Carolina sites in 26 126 adult emergency department patients being investigated for possible acute coronary syndrome and without ST-segment-elevation myocardial infarction...

Management of patients with acute chest pain poses a significant challenge in identifying those requiring urgent coronary reperfusion. Electrocardiogram (ECG) constitutes the cornerstone in making prompt clinical decisions by identifying ST-segment elevation, commonly associated with ST-segment elevation myocardial infarction. It is important to note that ST-segment elevation can also be a manifestation of various cardiac and non-cardiac conditions, from acute myocarditis, early repolarization syndrome, acute pericarditis, and left bundle branch block to unknown origins...

Myocardial injury is a known complication following acute carbon monoxide (CO) poisoning, yet there is little literature on this subject. Here, we present the case of a 56-year-old man admitted to the emergency room with severe CO poisoning. The electrocardiogram (ECG) at admission revealed an ST-segment elevation in leads II, III, and aVF, with an elevated troponin-T level. The patient was initially treated with hyperbaric oxygen, with improvement of symptoms and ECG normalization. He was later admitted for coronary angiography, which revealed an occlusion of the right coronary artery...

Ischemic heart disease (IHD) is a critical issue during pregnancy. The term comprises both pre-existing conditions and acute coronary syndrome (ACS) in pregnancy including pregnancy-associated myocardial infarction (PAMI), which can have a significant impact on maternal and fetal outcomes. This review provides a complete guide to managing IHD in pregnant women, emphasizing the importance of multidisciplinary care and individualized treatment strategies. Cardiovascular disease, particularly IHD, is now the leading cause of maternal mortality worldwide...

INTRODUCTION: Post-infarction ventricular septal defect (PIVSD) is one of the most serious mechanical complications of acute myocardial infarction (AMI). Over the last decade, percutaneous closure is increasingly undertaken, with results similar to cardiac surgery. We present a case of ST-elevated anterior AMI, complicated by apical PIVSD successfully treated with transcatheter closure. CASE REPORT: An 83-year-old man was hospitalized for chest pain occurred 18 hours before, during the night time...

Background : Acute Coronary Syndrome (ACS), with or without ST-segment elevation, is a major contributor to global mortality and morbidity. Swift diagnosis and treatment are vital for mitigating cardiac damage and improving long-term outcomes. The 12-lead electrocardiogram (ECG) currently serves as the gold standard for diagnosis in ACS with ST-segment elevation and may support the diagnosis in ACS without ST-segment elevation. However, the growing prevalence of smartwatches enables the acquisition of electrocardiographic data without traditional ECG equipment...

An electrical storm (ES) is defined as the presence of at least three episodes of sustained ventricular tachycardia or ventricular fibrillation within 24 h. This patient had a previously known arterial hypertension, type II diabetes mellitus, and chronic kidney disease and has presented to the Emergency Department (ED) with symptoms of retrosternal chest pain lasting for several hours prior. The initial 12-lead electrocardiogram revealed ST segment elevation in the anterior leads (V1-V6). Emergent coronary angiography revealed an acute occlusion of the proximal left anterior descending artery (pLAD) and percutaneous coronary intervention was performed with successful implantation of one drug-eluting stent in the pLAD...

A 51-year-old male patient was brought to the emergency department (ED) by paramedics after an unwitnessed fall from a height while he was working. He sustained a severe head injury with a low Glasgow Coma Scale (GCS). After securing his airway and stabilizing the patient, a CT scan of the brain was done that revealed bilateral subdural hematomas, and an electrocardiogram (EKG) revealed an ST elevation inferior wall myocardial infarction (MI), which was suggested to be the cause of his fall. With the presence of two concomitant life-threatening medical conditions, it was a predicament which of the two pathologies to target first in treatment...

BACKGROUND: Acute myocardial injury is a common diagnosis in the emergency department and differential diagnoses are numerous. Cardiac magnetic resonance (CMR) strain sequences like fSENC are early predictors of myocardial function loss. This study assessed the potential diagnostic and prognostic benefits of a layer-specific approach. METHODS: For this prospective study patients in the emergency department fulfilling rule-in criteria for non-ST-elevation myocardial infarction (NSTEMI) received an ultra-fast fSENC CMR...

BACKGROUND: Acute coronary syndrome (ACS) in young women is poorly understood due to underdiagnosis and undertreatment. One of the possible risk factors for ACS in young women is antiphospholipid syndrome (APS). Coronavirus disease 2019 (COVID-19) vaccination also emerged as one of the possible risk factors for ACS during the COVID-19 pandemic. CASE PRESENTATION: Our patient, a 39-year-old Batak woman with dyslipidemia and family history of cardiovascular disease, experienced chest pain slightly improved at rest accompanied by autonomic symptoms...

A 28-year-old man diagnosed with triple positive antiphospholipid syndrome (APS) and undergoing warfarin experienced three separate admissions to the cardiac ward within a one-month period due to escalating chest pain. While the initial two admissions revealed normal results in cardiological investigations, such as blood tests, electrocardiogram, and echocardiography, the third admission unveiled signs of ST-elevation myocardial infarction (STEMI), despite the patient maintaining an INR (International Normalized Ratio) of 4...
