BACKGROUND: The association between the early repolarization pattern (ERP) and ventricular arrhythmias in patients with ST-segment elevation myocardial infarction (STEMI) remains uncertain. We hypothesized that ERP predicts the risk of sustained ventricular tachycardia (VT)/ventricular fibrillation (VF) during the acute phase of anterior STEMI.Methods and Results:We enrolled 1,460 consecutive patients with acute anterior STEMI. We identified an ERP-positive group and a 1:6 propensity-matched ERP-negative group of 183 and 471, respectively...

BACKGROUND: ST elevation Myocardial infarction is a medical emergency. A variety of noncardiac conditions had been known to mimic the ECG changes that are seen in acute coronary syndrome. Although the common ECG changes that are documented with raised intracranial pressure are T inversions, prolongation of QT interval and sinus bradycardia, ST elevation or depression, arrhythmias and prominent U waves have also been recognized. However, ST elevations in association with primary intracranial tumours are rarely reported...

AIMS: Ventricular arrhythmia (VA) bursts following recanalisation in acute ST-elevation myocardial infarction (STEMI) are related to larger infarct size (IS). Inadequate microvascular reperfusion, as determined by microvascular obstruction (MVO) using cardiac magnetic resonance imaging (CMR), is also known to be associated with larger IS. This study aimed to test the hypothesis that VA bursts identify larger infarct size in spite of optimal microvascular reperfusion. METHODS: All 65 STEMI patients from the Maastricht ST elevation (MAST) study with brisk epicardial flow (TIMI 3), complete ST recovery post-percutaneous coronary intervention and early CMR were included...

The Brugada syndrome is a rare condition associated with increased risk of ventricular tachyarrhythmias and sudden cardiac death (SCD). The Brugada pattern on electrocardiogram (EKG) is known to be revealed by several precipitants including febrile illnesses. The appearance of a Brugada pattern on EKG with fever may indicate an elevated risk of arrhythmia or sudden cardiac death. We report a case in which the electrocardiographic abnormality of Brugada pattern induced by sepsis was initially misinterpreted as a ST-segment elevation myocardial infarction (STEMI)...

INTRODUCTION: Myocardial perfusion, when assessed by myocardial blush grade (MBG) is an independent predictor of major adverse cardiac outcomes. The terminal part of repolarization, measured as the interval from the peak to the end of the T wave (Tpe), is a relatively novel indicator of ventricular arrhythmias. The relations between MBG and Tpe interval have not been examined before. We aimed to evaluate the relationship between MBG and Tpe and Tpe/QT ratio after successful primary percutaneous coronary intervention (PCI) in acute ST-segment elevation myocardial infarction (STEMI)...

We report the case of a woman in her 70s presenting to the emergency department with syncope, troponemia, and an electrocardiogram with deep symmetric T-wave inversions in V2 and V3 and prolonged QTc. Her presentation was concerning for acute coronary syndrome, Wellens syndrome in particular, given the elevated troponin levels, lack of ST segment changes, and characteristic T-wave findings. The diagnosis was confirmed with angiography that showed a critical left anterior descending (LAD) artery occlusion. Since myocardial infarction does not typically present with syncope, we explored the differential diagnoses for T-wave inversions, which include electrolyte abnormalities, medications, intracranial hemorrhage, pulmonary embolism, and other cardiac diseases that were ruled out in our patient...

Atrial fibrillation (AF) is the most common supraventricular arrhythmia following ST elevation myocardial infarction (STEMI). Oxidative stress and inflammation may cause structural and electrical remodeling in the atria making these critical processes in the pathology of AF. In this study, we aimed to evaluate the association between total oxidative status (TOS), total antioxidative capacity (TAC) and high-sensitivity C-reactive protein (hs-CRP) in the development of AF in patients presenting with STEMI. This prospective cohort study consisted of 346 patients with STEMI...

OBJECTIVES: To examine whether the CADILLAC risk score is an effective method of patient stratification for early discharge following ST elevation myocardial infarction (STEMI). BACKGROUND: Patients with STEMI are typically hospitalized to monitor for serious complications such as arrhythmias, heart failure, and reinfarction. Optimal length of stay is unclear. Whether low risk patients can be safely discharged before 72 hr of hospitalization is unclear. METHODS: Patients with STEMI who underwent successful PCI were retrospectively stratified using CADILLAC risk score to low risk (n = 123) and intermediate to high risk (n = 105)...
