The 41 patients (aged 59 ± 10 years, 40% females) were divided into three groups; those receiving (i) ACE inhibitors; or (ii) CCB or (iii) combination of ACEI and CCB. All the three groups had a background of diuretic treatment for optimal blood pressure control.</p><p><b>Results. </b> There were no statistically significant differences in the mean LVMI or sitting blood pressure between treatment groups.
