Assessment of coronary thrombolysis.

The efficacy of coronary thrombolysis may be assessed by several invasive and noninvasive means, including coronary angiography, contrast and radionuclide angiography, thallium 201 or 99mTc-pyrophosphate scintigraphy, positron emission tomography, cardiac ultrasonography, electrocardiography, and analysis of plasma creatine kinase activity. Each technique has its own strengths and limitations, but when used in concert these methods may provide insight into the physiology of coronary reperfusion and the efficacy of reperfusion in individual patients and populations.
