Quantitative segmental analysis of myocardial perfusion to differentiate stress cardiomyopathy from acute myocardial infarction: A myocardial contrast echocardiography study.

ABSTRACT:

Background

Both stress cardiomyopathy (SCMP) and acute myocardial infarction (AMI) present with similar clinical symptoms and signs, and apical akinesis.

Hypothesis

Quantitative segmental analysis of myocardial contrast echocardiography (MCE) helps to differentiate AMI from SCMP.

Methods

Real-time MCE was performed in 33 consecutive patients who presented with an acute symptom/sign and a new apical akinesis on echocardiography. In 18 left ventricular (LV) myocardial segments, a replenishment curve was obtained in each segment to measure peak plateau myocardial contrast intensity (MCI) (A) and the replenishment curve slope (β). The calibrated MCI was also measured in each segment.

Results

Among 33 patients, 22 were diagnosed with SCMP and 11 were diagnosed with
