Answer

In severe chronic AR, vasodilator therapy may be used in select conditions to reduce afterload in patients with systolic hypertension, in order to minimize wall stress and optimize LV function. In normotensive patients, however, vasodilator therapy is not likely to reduce regurgitant volume (preload) significantly and thus may not be of clinical benefit. [34]
