Regadenoson and Adenosine
Coronary Artery Disease
About this trial
This is an interventional diagnostic trial for Coronary Artery Disease focused on measuring Coronary artery disease, Regadenoson, Adenosine, Maximal hyperemia, Fractional flow reserve, FFR
Eligibility Criteria
Inclusion Criteria:

- Known conduction disturbances (2nd-3rd degree heart-block, sick sinus without pacemaker or long QT-syndrome)
- Severe hypotension (RR <90 mmHg)
- Patients in whom no access to the coronary circulation can be obtained by the femoral artery or in whom femoral access was problematic
- Coronary anatomy not suitable for FFR measurement (extremely tortuous or calcified coronary vessels)
- Previous coronary bypass surgery
- Recent ST elevation myocardial infarction (<5 days)
- Recent non-ST elevation myocardial infarction (<5 days) if the peak CK is >1000 IU
- Inability to provide informed consent
