This case report deals with induced regional wall motion abnormalities that spontaneously disappeared during an echocardiographic stress test with dipyridamole. A patient underwent this test because of atypical chest discomfort and a positive result of exercise stress test. Transient septal, apical and anterior akinesia were observed after the first dose of dipyridamole, but they were short-lasting and did not return during the continuation of the test.

It remains to be determined whether echocardiographic or scintigraphic imaging modes are equivalent. The aim of our study was to compare the prognostic information obtained early after an acute uncomplicated myocardial infarction through high-dose dipyridamole coupled with echocardiography or scintigraphy via Tc 99m sestamibi SPECT imaging.

The aim of our study was to assess the prognostic information obtained with exercise scintigraphy performed for routine follow-up or reappearance of symptoms.
Methods: We studied 75 patients referred to our Center at a mean of 38 +/- 53 months from the revascularization procedure and prospectively followed them for 38 +/- 24 months.
Aim: Verify the value of the combined use of Dipyridamole Stress Echocardiography (DSE) and Exercise Testing (ET) for predicting cardiac events after Thrombolysed Myocardial Infarction (TMI).
Study Design: Prospective, with a medium follow-up of 221 days (range 30-446).
Clinical Settings: Coronary Care Unit with Cardiology Service.
