Stress-induced ST-segment elevation after a recent myocardial infarction: myocardial necrosis, viability or both?

Relation between ST segment elevation during dobutamine stress test and myocardial viability after a recent myocardial infarction.

OBJECTIVE To assess the relation between ST segment elevation during the dobutamine stress test and late improvement of function after acute Q wave myocardial infarction. PATIENTS AND DESIGN 70 patients were studied a mean (SD) 8 (3) days after acute myocardial infarction with high dose dobutamine-atropine stress echocardiography and a follow up echocardiogram at 85 (10) days. A score model b...

Myocardial Hemorrhage After Acute Reperfused ST-Segment–Elevation Myocardial Infarction

Reciprocal ST-segment depression associated with exercise-induced ST-segment elevation indicates residual viability after myocardial infarction.

OBJECTIVES We evaluated the clinical significance of reciprocal ST-segment depression associated with exercise-induced ST-segment elevation for detecting residual viability within the infarcted area. BACKGROUND Although the relation between residual viability and exercise-induced ST-segment elevation has been described, there are no reports focusing on the relation between myocardial viabilit...

Anticoagulation for ST-segment elevation myocardial infarction.

Adjunctive anticoagulant therapy reduces the risk of recurrent infarction and death in patients with STsegment elevation myocardial infarction (STEMI) receiving fibrinolytic therapy.1–5 Unfractionated heparin (UFH), the first anticoagulant evaluated for this indication,1 continues to be used because of its predominantly nonrenal clearance, short half-life, reversibility, and the familiarity of ...

False Positive ST-Segment Elevation Myocardial Infarction

Acute ST-segment elevation myocardial infarction (STEMI) is a serious disease in clinical practice. The rapid and accurate diagnosis of this critical illness can lead to prompt reperfusion, and it enables the reduction of cardiac ischemic damage and results in improved subsequent outcomes. The shorter the time to reperfusion, the greater the benefits. The American College of Cardiology/American...
