Left ventricular (LV) filling was studied in 18 healthy subjects and 19 mildly hypertensive patients before and after 50% and 70% of maximal supine exercise using radionuclide ventriculography. In addition, in the hypertensive patients, the effects of oral verapamil and lisinopril treatment on LV filling before and after exercise were studied. At rest, hypertensive patients compared with healthy subjects had a lower peak filling rate, ratio of peak filling to peak emptying rate, first-half filling fraction, and a longer isovolumic duration. With exercise, LV filling measures were not different between healthy Subjects and hypertensive patients. In the hypertensive patients at rest, compared with before treatment, lisinopril prolonged isovolumic duration and verapamil had no effect on LV filling; at 50% maximal exercise compared with before treatment, verapamil shortened the time to peak filling rate and isovolumic duration and increased first-half filling fraction but, at 70% maximal exercise, verapamil had no effect, whereas lisinopril did not alter exercise LV filling at either exercise level. Thus, the early abnormal LV filling in mildly hypertensive patients is influenced by therapeutic interventions both at rest and with exercise. Am J Hypertens 1994;7:695–702.
