Following a hypertension symposium in Los Angeles, CA, in October 2005, an expert panel discussion was held to discuss resistant hypertension. Are there patients whose blood pressures cannot be controlled? Do inappropriate uses of medications or drug combinations or, on the other hand, poor adherence on the part of patients, play a major role in resistance? Dr. Marvin Moser, Clinical Professor of Medicine at the Yale University School of Medicine, New Haven, CT, moderated the discussion. Participants on this panel included Dr. William Cushman of the University of Tennessee College of Medicine, Memphis, TN, and Dr. Joel Handler of the Kaiser Permanente Group in Anaheim, CA.
