E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Aim of the present study is to directly compare the quantitative flow responses or Regadenoson against adenosine using cardiac O-15-water PET imaging in patients with suspected or known CAD. The study will provide information on whether:
1) Regadenoson induces similar quantitative increase in myocardial perfusion than adenosine
2) The ischemic and non-ischemic regions have similar response to Regadenoson than to adenosine. |
Tämän tutkimuksen tavoitteena on verrata adenosiinin ja regadenosonin aiheuttamia määrällisiä muutoksia sydänlihaksen verenvirtauksessa potilailla, joilla tiedetään tai epäillään olevan sepelvaltimotauti. Tämän tutkimuksen on myös tarkoitus selventää, lisääkö Regadenoson sydänlihaksen verenvirtausta saman verran kuin adenosiini. Lisäksi selvitetään reagoivatko terveet sydänlihasalueet samalla tavalla sekä regadenosoniin että adenosiiniin. |
|
E.2.2 | Secondary objectives of the trial |
We will find out weather similar absolute perfusion cut-off values can be used for diagnostic purposes. |
Selvitämme myös, voidaanko samoja diagnostisia raja-arvoja käyttää molemmilla lääkeaineilla. |
