Normalization of structural cardiovascular changes during antihypertensive treatment with a regimen based on the ACE-inhibitor perindopril

Blood Press. 1995 Jul;4(4):241-8. doi: 10.3109/08037059509077602.


Untreated essential hypertension is associated with left ventricular hypertrophy (LVH) and structural changes in resistance vessels. The aim of this study was to establish the effect of perindopril based antihypertensive therapy on media thickness to lumen diameter (media:lumen) ratio of peripheral resistance vessels and left ventricular mass in essential hypertension. Twenty-five patients with newly diagnosed or poorly regulated essential hypertension were treated with perindopril. Insufficient treatment response (DBP > 90 mmHg) led to addition of isradipine, and hydralazine was used as a tertiary drug if necessary. Gluteal subcutaneous biopsies were taken surgically at baseline and after 9 months of successful treatment. Two small resistance arteries were isolated and mounted in a small vessel myograph, and media:lumen ratio (%) was measured under standardized conditions. Left ventricular mass was determined by echocardiography. Mean (SD) media:lumen ratio decreased from 9.8 (2.6) % to 7.8 (1.9) % (p < 0.05), while left ventricular mass decreased from 299 (75) g to 199 (53) g (p < 0.001). Correlation was found between changes in left ventricular mass index and media:lumen ratio (r = 0.62, p < 0.01). It is concluded that a perindopril based regimen efficiently normalizes resistance artery structure and left ventricular hypertrophy in essential hypertension within one year of treatment. The impact of these findings on the excess cardiovascular morbidity and mortality in arterial hypertension remains to be investigated.
