Design outcomes

Primary

Measure	Time frame
To evaluate the usefulness of increased injection dose of adenosine to achieve sufficient hyperemic status under the condition of caffeine intake.	—

Secondary

Measure	Time frame
(1) To evaluate the relationship between myocardial flow reserve determined by MRI and hemodynamic parameters including blood pressure, heart rate and cardiac output under the condition of caffeine intake. (2) To determine the usefulness of the hemodynamic parameters to estimate hyperemia induced by adenosine under the condition of caffeine intake.	—
