Prehospital ST-segment elevation myocardial infarction (STEMI) in Queensland, Australia: findings from 11 years of the statewide prehospital reperfusion strategy.

This study described real-world clinical practice in prehospital management of STEMI patients in Queensland, Australia. Methods. Retrospective analysis of data sourced from the STEMI database of the Queensland Ambulance Service, Australia. Adult STEMI patients identified by paramedics between February 2008 and December 2018 in Queensland were included. Key aspects of prehospital STEMI care were described. Clinically-important time intervals from symptom onset to reperfusion were reported. Results. A total of 8,388 patients were included. The proportion of patients receiving prehospital reperfusion treatment has improved markedly, increasing from 34% in 2008 to 65% in 2018 (p

Authors: Kamizono Y, Ikeda D Abstract A 77-year-old woman was admitted to our hospital with severe ongoing chest pain. Electrocardiography showed ST-segment elevation in the inferior leads and tall R waves in leads V1-2. Posterior-inferior myocardial infarction was diagnosed. Emergent coronary angiography (CAG) revealed the wrap-around left anterior descending artery (LAD) with total occlusion distal to the cardiac apex. She underwent percutaneous coronary intervention (PCI). Despite difficulty navigating the long and tortuous LAD, we successfully performed reperfusion of the wrap-around LAD. CAG post-PCI showed th...

Authors: Park K, Park JS, Cho YR, Park TH, Kim MH, Yang TH, Kim DI, Kim JH, Lee YH, Lee DW, Seo J, Lee GY, Kim YD Abstract BACKGROUND AND OBJECTIVES: In acute ST-segment elevation myocardial infarction (STEMI), on-site transmission of electrocardiogram (ECG) has been shown to reduce systemic time delay to reperfusion and improve outcomes. However, it has not been adopted in community-based emergency transport system in Korea. METHODS: Busan Regional Cardio-cerebrovascular Center and Busan Metropolitan City Fire and Safety Headquarters (BMFSH) jointly developed and conducted a pre-hospital ECG transmission progr...

Conclusions: There is a higher percentage of coronary interventionism and improvement in pharmacological treatment, which is reflected in lower mortality. The substantial burden of T2DM could be related to a higher number of cases of STEMI. Diabetics with precedent percutaneous coronary intervention and smokers with previous heart surgery have an increased risk of subsequent infarction. PMID: 32695506 [PubMed]

We reported the overall accuracies of 97.41% for healthy control (HC) vs. MI, 89.41 ± 9.89 for left and right culprit arteries vs. others, 88.2 ± 11.6 for left main arteries vs. right-coronary-ascending (RCA) and 93.67 ± 4.89 for left-anterior-descending (LAD) vs. left-circumflex (LCX). The IRA localization from paper ECG can be used to timely triage the patients with acute coronary syndromes to the percutaneous coronary intervention facilities.

Authors: Kim HN, Lee JH, Park HS, Yang DH, Jang SY, Bae MH, Cho Y, Chae SC, Lee YH Abstract A 60-year-old male patient with coronavirus disease-2019 showed new onset ST-segment elevation in V1-V2 leads on electrocardiogram and cardiac enzyme elevation in intensive care unit. He had a history of type 2 diabetes mellitus, hypertension, and dyslipidemia. He was receiving mechanical ventilation and veno-venous extracorporeal membrane oxygenation treatment for severe hypoxia. Two-D echocardiogram showed regional wall motion abnormalities. We performed primary percutaneous coronary intervention for acute myocardial infar...

Authors: Eckner D, Pauschinger M, Ademaj F, Martinovic K Abstract This disease with its multiple ischemic and non-ischemic manifestations is classified based on the fourth universal definition of myocardial infarction (MI). An acute myocardial injury is defined as a significant increase of cardiac troponins (cTn). In patients with an additional myocardial ischemia, which is defined by certain clinical, electrocardiographic, imaging and angiographic criteria, the diagnosis of acute MI can be made. Etiologically, MI can be divided into 5 types: type 1 ischemic by plaque rupture or plaque erosion with t...

This study investigated the application of these scores in predicting the short-term risk of a major adverse cardiac event (MACE) in patients with chest. A total of 509 patients were analyzed. All patients were followed up for 30  days after visiting our emergency department. At 30 days post-admission, the primary outcome (MACE) was recorded in 92 patients (18.1%), 88 (95.6%) of whom had experienced an acute myocardial infarction. Thirty-seven (40.2%) of the patients with a MACE underwent percutaneous coronary intervention and six patients (6.5%) died. The HEART and GRACE scores were both significantly higher in ...

Authors: Arai R, Fukamachi D, Akutsu N, Tanaka M, Okumura Y Abstract A 76-year-old man suffering from chest pain was admitted to our hospital with a suspected acute myocardial infarction (AMI). Emergent coronary angiography revealed a totally occluded proximal left circumflex artery (LCX). During primary percutaneous coronary intervention, his blood pressure suddenly fell within seconds, and he developed pulseless electrical activity (PEA). Surprisingly, the 12-lead electrocardiogram (ECG) findings including the heart rate remained unchanged before and after the PEA, but a heart rate reduction and asystole occurred...

Abstract Coronavirus disease 2019 (COVID-19) is a recently recognised pandemic spreading rapidly from Wuhan, Hubei, to other provinces in China and to many countries around the world. The number of COVID-19-related deaths is steadily increasing. Acute ST-segment elevation myocardial infarction (STEMI) is a disease with high morbidity and mortality rates, and primary percutaneous coronary intervention is usually recommended for the treatment. A patient with diabetes mellitus and hypertension for five years was admitted to the emergency unit with symptoms of fever, cough and dyspnoea. These symptoms were consistent ...

Rationale: The De Winter ST/T-wave complex is a rare and special electrocardiogram (ECG) manifestation in some patients with a total or subtotal occlusion in the proximal left anterior descending (LAD) coronary artery. It mainly appears as an ST-segment superior oblique depression instead of an ST elevation. However, a transitory change of the De Winter ST/T-wave complex has not been reported previously. Patient concerns: A 40-year-old man developed sudden precordial dull and unrelieved pain. One hour later, he suddenly lost consciousness when he arrived at the emergency department. After successful cardiopulmonary re...
