To the Editor.—
The conclusion advanced by Donna Zimmerman and Brent M. Parker, MD (1981;246:2345), that anginal-type pain is unrelated to pulmonary hypertension does not seem to have resolved the issue at all.Their retrospective study attempted to correlate anginal-type pain with pulmonary pressure measured during scheduled cardiac catheterization, while the patient was not experiencing pain. To transpose my argument to more familiar territory and with what we know today, would we not be seriously misguided if we established correlatives of pain by using resting electrical, nuclear, or hemodynamic measurements obtained during a pain-free period in patients with angina pectoris owing to coronary artery disease?
