Attempts to monitor coronary sinus adenosine as a clinical marker of myocardial ischemia in humans have been disappointing. Accordingly, procedures have been developed for detecting adenosine in blood collected from the human coronary sinus. Collection involves using a double-lumen metabolic catheter, which allows blood to be mixed with a stop solution at the catheter tip, thereby minimizing adenosine formation and degradation. A five-component stop solution almost completely arrests adenosine formation and degradation. Adenosine analysis is improved by using both boronate and C18 Sep-Pak columns to purify and concentrate adenosine in human plasma before HPLC. Plasma adenosine in the coronary sinus of patients with and without coronary artery disease, measured before and during peak atrial pacing, showed a twofold atrial pacing-induced increase in adenosine in the patients with coronary artery disease (n = 9, P less than 0.001) but no change in the patients with normal epicardial coronary arteries (n = 6). These preliminary results indicate that coronary sinus adenosine may provide an index of myocardial ischemia in patients with coronary artery disease.
