Myocardial infarction (MI), is used synonymously with coronary occlusion and heart attack, yet MI is the most preferred term as myocardial ischemia causes acute coronary syndrome (ACS) that can result in myocardial death. Oxygen is administered at 4 L/min as soon as it is available. Diagnosing a type 2 MI requires evidence of acute myocardial ischemia (Figure 2) with an elevated troponin but must also have at least one of the following: 2. Myocardial infarction (MI) refers to tissue death of the heart muscle caused by ischaemia, that is lack of oxygen delivery to myocardial tissue.It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. ST-segment elevation myocardial infarction (STEMI): If the complete obstruction of a coronary artery occurs, resulting in the death of heart muscle tissue, we refer to that as STEMI, the worst form of ACS.

Myocardial infarction (MI) (colloquially known as a heart attack) results from interruption of myocardial blood flow and resultant ischaemia and is a leading cause of death worldwide.. MI is mainly due to underlying coronary artery disease.When the coronary artery is occluded, the myocardium is deprived of oxygen. Eskola MJ, Nikus KC, Holmvang L, et al. NB: The magnitude of reciprocal change in inferior leads is determined by the magnitude of ST elevation in I and aVL (as these leads are electrically opposite III and aVF), and hence may be minimal or absent in anterior STEMIs that do not involve high lateral leads.

Normal sinus rhythm with 1st degree AV block, There are premature atrial complexes (beat 4 on the rhythm strip) and multifocal ventricular ectopy (PVCs of two different types), indicating an “irritable” myocardium at risk of ventricular fibrillation, There is progressive ST elevation and Q wave formation in V2-5, ST elevation is now also present in I and aVL, There is some reciprocal ST depression in lead III, ST elevation in V1-6 plus I and aVL (most marked in V2-4), Minimal reciprocal ST depression in III and aVF, Q waves in V1-2, reduced R wave height (a Q-wave equivalent) in V3-4, There is a premature ventricular complex (PVC) with “R on T’ phenomenon at the end of the ECG; this puts the patient at risk for malignant ventricular arrhythmias. There is a septal STEMI with ST elevation maximal in V1-2 (extending out to V3). This book focuses on the coronary bioresorbable scaffold, a new interventional treatment for coronary artery disease, differentiated from a permanent metallic stent.
