Text: With lisinopril, collagen volume fraction decreased from 6. 9 + / -0. 6 % to 6. 3 + / -0. 6 % (P : < 0. 05 versus HCTZ) and myocardial hydroxyproline concentration from 9. 9 + / -0. 3 to 8. 3 + / -0. 4 microg/mg of LV dry weight (P : < 0. 00001 versus HCTZ) ; this was associated with an increase in the early filling and atrial contraction LV peak flow velocity ratio from 0. 72 + / -0. 04 to 0. 91 + / -0. 06 (P : < 0. 05 versus HCTZ) and a decrease in isovolumic relaxation time from 123 + / -9 to 81 + / -5 ms (P : < 0. 00002 versus HCTZ).
