Lexiscan / Adenosine Myocardial Perfusion Imaging

Lexiscan / Adenosine Perfusion Imaging (L/AMPI) is a test that evaluates the blood flow to the heart at rest and under stress conditions. It is used instead of the treadmill for patients who cannot walk on the treadmill for any reason. An intravenous catheter is placed in your arm and a scanning tracer is injected. After adequate circulation, imaging of your heart at rest is done.

You will then be asked to under go “stress testing” with medication. Upon completion, another tracer is injected. Imaging is done again after the tracer has circulated adequately. Total test time can be up to 4 hours to complete and it is sometimes necessary to perform this test over 2 days. The first day's testing takes about 1 1/2 hours and the second day's testing takes about 1 1/2 hours as well.

Special preparation is required so check with the clinical staff for specific test instructions. MPI testing is being performed in: Cleveland (NOH), Elyria (NOH), Lorain (NOH), Medina (NOH & OMG), Middleburg Heights (Southwest - NOH & OMG), Sandusky (NOH) and Westlake (NOH & OMG).
