Adenosine's vasodilator properties make it useful in stress testing as an alternative to exercise. Patients are advised not to drink coffee beforehand, since caffeine will block the effect of adenosine on the coronary arteries. Sometimes they will complain of a headache--a caffeine headache--from the unopposed action of adenosine.
