“…Some studies show improved filling (in association with, but possibly independent of, LV mass regression) [100,101]. Two studies, including one in elderly hypertensive patients, failed to demonstrate LV mass regression and improvement in diastolic function [96,102]. Because β-blockade antagonizes catecholamine-mediated LV relaxation, it has been suggested that it can improve diastolic function only if accompanied by blood pressure reduction, relief of ischemia, and prolongation of the time for LV filling [88•].…”
