Ultrasonic tissue characterization in predicting residual ischemia and myocardial viability for patients with acute myocardial infarction

Determination of Successful Reperfusion After Thrombolysis for Acute Myocardial Infarction

“…This suggests that cyclic IBS has the potential to detect viable myocardium and predict functional recovery. 2,6,7 Animal and in vitro studies support this. 8 -11 However, most studies to date have involved small patient numbers.…”

“…3,8,20 Studies in the setting of myocardial infarction have shown that this parameter can accurately diagnose myocardial infarction 3,4 and is capable of identifying stunned as opposed to infarcted myocardium, 3,7 particularly when used in conjunction with dobutamine stress testing or thallium scanning. 7 However, stress testing can be difficult in the acute setting. Only 2 studies 3,5 have made an attempt to correlate the measurement of cyclic IBS from the IRA with coronary angiographic findings.…”

Caracterização tecidual ultra-sônica em síndromes coronarianas agudas

“…In addition to IBS variability, changes in pattern or delay are documented and considered more sensitive, and stand as a possibility for the purpose of predicting the viability of injured myocardial tissue 9,10,12,[15][16][17][18][19][20][21] . Such phenomenon has been investigated through techniques that are not available in the equipment used in the present study.…”

“…The analysis of synchronicity parameters (delay index and pattern) has been attractive from its potential to identify myocardial viability 9,10,12,[15][16][17][18][19][20][21] . In the present study such analysis was limited to echocardiographic assessment of ventricular segmental motility recovery at rest.…”

Integrated backscatter for the assessment of myocardial viability

“…It is applicable, therefore, in unstable patients, and some investigators have attempted to use this technique to predict the patency of infarct-related arteries [9,10]. In a recent study, Hancock et al [10] performed ultrasonic tissue characterization in 113 patients with acute myocardial infarction 90 min after thrombolysis and immediately before coronary angiography.…”
