CLINICAL PRESENTATION Acute Myocardial Infarction is precipitated by exertion, exercise, emotional stress, medical and surgical disease and interventions. Circadian variation – AMI is more common in early morning hours due to increase in sympathetic tone and increased thrombolytic tendency from 4 to 12 AM. Acute myocardial infarction (AMI) is the...

Acute Myocardial Infarction AMI Causes PATHOPHYSIOLOGY Atherosclerosis and Etiology Acute coronary syndrome (ACS) may present as unstable angina (no ST segment elevation), or acute myocardial infarction. Acute myocardial infarction (AMI) implies irreversible damage to the myocardium. MI Causes usually occurs when an atheromatous plaque in a coronary artery ruptures, and...

2D echocardiography Doppler echocardiography A noninvasive diagnostic method that uses ultrasound to visualize cardiac structures. Shows global or RWMA (Regional Wall Motion Abnormality) in infarction and ischemia. in which dobutamine is given to patients to increase the workload of the heart, and then the heart is evaluated with ultrasonic...
