ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock

…In the setting of ST elevation myocardial infarction (STEMI), cardiogenic shock most commonly reflects severe left ventricular (LV) dysfunction, accounting for approximately 80% of cases…

Post-Infarction Mechanical Complications: Ventricular Septal, Free-Wall, and Papillary Muscle Rupture

…after ST elevation myocardial infarction (STEMI). The principal lesions are: Ventricular septal rupture (VSR), producing an acute left to right shunt. Ventricular free wall rupture…

ECG manifestations of left main coronary artery (LMCA) occlusion and critical stenosis

…resulting extensive ischemia causes immediate myocardial stunning (akinesia) and electrical instability. Fewer than 1% of patients with ST elevation myocardial infarction (STEMI) who reach the…

Spontaneous Coronary Artery Dissection

…with non SCAD ACS. SCAD may present with: ST elevation myocardial infarction (STEMI). Non ST elevation myocardial infarction (NSTEMI). Unstable myocardial ischaemia. Ventricular arrhythmia or…

Left Bundle Branch Block: ECG criteria and clinical implications

…in STEMI : Patients presenting with ST elevation myocardial infarction (STEMI) and bundle branch blocks exhibit higher long term and in hospital mortality rates, as well…

Left bundle branch block (LBBB) in acute myocardial infarction: the Sgarbossa criteria

…fibrosis of the conduction system and acute myocardial infarction (particularly anterior STEMI). Hence, an acute myocardial infarction may actually result in LBBB which then masks…

Factors that modify the natural course in acute myocardial infarction (AMI)

…STE ACS (STEMI) is slightly simplified. In reality, the course in acute myocardial infarction (AMI) is modified by several factors. The most important of these…

ST segment depression in myocardial ischemia and differential diagnoses

ECG Myocardial ischemia and infarction ST segment depression due to acute myocardial ischemia ST segment depressions caused by ischemia are characterized by a horizontal or…

ST-Segment Elevation Myocardial Infarction: Diagnosis and ECG Criteria

…abnormalities such as prior infarction, left bundle branch block, Wolff–Parkinson–White patterns or ventricular pacing STEMI and non ST segment elevation myocardial infarction (NSTEMI)…

Left Ventricular Thrombus After Myocardial Infarction

…patients after ST segment elevation myocardial infarction (STEMI), with rates approaching 25% after anterior MI. Thrombi may form early, within 48–72 hours of infarction…
