title: Effect of perindopril on coronary remodelling: insights from a multicentre, randomized study.
abstract: OBJECTIVE
  This study sought to evaluate the effect of perindopril in coronary remodelling.
  
  
  RESULTS
  In this sub-study of a double-blind, multicentre trial, patients without clinical evidence of heart failure were randomized to perindopril 8 mg/day or placebo for at least 3 years and IVUS investigation was performed at both time-points. Positive and negative remodelling were defined as a relative increase (positive remodelling) or decrease (negative remodelling) of the mean vessel cross-sectional area (CSA)>2 SD of the mean intra-observer difference. A total of 118 matched evaluable IVUS (711 matched 5 mm segments) were available at follow-up. After a median follow-up of 3.0 (inter-quartile range 1.9, 4.1) years, there was no significant difference in the change of plaque CSA between perindopril (360 segments) and placebo (351 segments) groups, P=0.27. Conversely, the change in vessel CSA was significantly different between groups (perindopril -0.18+/-2.4 mm2 vs. placebo 0.19+/-2.4, P = 0.04). Negative remodelling occurred more frequently in the perindopril than in the placebo group (34 vs. 25%, P=0.01). In addition, the placebo group showed a larger, although not significant, mean remodelling index (RI) than the perindopril group (1.03+/-0.2 vs. 1.00+/-0.2, P=0.06). The temporal change in vessel dimensions assessed by the RI was significantly correlated with the change in plaque dimensions (r=0.48, P<0.0001).
  
  
  CONCLUSIONS
  In this sub-analysis of a multicentre, controlled study, long-term administration of perindopril was associated with a constrictive remodelling pattern without affecting the lumen.
