In the immediate aftermath of reperfusion therapy for acute myocardial infarction (AMI)—whether it be primary coronary angioplasty or thrombolysis—the clinician must determine whether the infarct-related artery is patent and if so, whether successful reperfusion has been achieved. Answering these questions expeditiously is important for subsequent treatment strategies: if thrombolytic therapy has failed, for example, the patient may be taken to the cardiac catheterization laboratory for rescue angioplasty. Clinical variables such as the resolution of ST segment elevations or chest pain, or the appearance of reperfusion arrhythmias, are not consistently reliable in determining whether thrombolytic therapy has been successful [1]. Furthermore, even when the patency of the infarct artery has been confirmed by coronary arteriography, it is not always clear that successful microvascular perfusion has actually occurred [2].It is also of interest to identify the extent of residual myocardial viability in both the immediate and the more chronic period following reperfusion for AMI, because this determines the likelihood of recovery of systolic function and the risk: benefit ratio for subsequent revascularization or other supportive measures. Current methods for assessing myocardial viability after infarction, such as thallium scintigraphy and positron emission tomography [3], are limited because they require the use the radioisotopes, are expensive, are primarily located in tertiary care or research facilities, or are not moveable to the bedside of unstable patients.
