I am delighted to have this opportunity to comment upon "Incidence of Primary Aldosteronism" by Dr. Kaplan. I shall make no attempt at a point by point rebuttal of the same argument that Dr. Kaplan has raised on two previous occasions.1,2 My purpose in responding is to put in proper perspective the entire content of Dr. Kaplan's comment in the hope that the subject will not be raised again.
First, I am gratified that the writer sees fit to state "regardless of its incidence, the recognition of normokalemic primary aldosteronism as a masquerade of 'essential' hypertension is a discovery of great importance," and that "the availability of better diagnostic procedures and the insights into our understanding of the role of aldosterone in hypertension are, in themselves, major advances which have resulted from the stimulus provided by Dr. Conn and his co-workers." If these statements are acceptable to others
