ABSTRACT
<p><b>OBJECTIVE</b>To investigate the association between the anti-atherosclerotic effects of amlodipine and angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism in elderly essential hypertensive (EH) patients.</p><p><b>METHODS</b>A total of 220 EH patients were treated with amlodipine (2.5 - 10 mg, once daily) for twelve months and complete data were obtained from 208 patients with genotypes of II (n = 90), ID (n = 91) and DD (n = 27). The indices of carotid arterial were compared before and post amlodipine treatment in patients with identical genotype and among different ACE genotypes and each genotype post therapy.</p><p><b>RESULTS</b>The carotid mean intimal-medial thickness (MIMT) was slightly decreased in EH patients with ID and DD genotypes and significantly decreased in EH patients with II genotype (0.96 +/- 0.12 vs. 0.92 +/- 0.13, P < 0.01) compared to pre-treatment values. The decreased degree of MIMT (DeltaMIMT) in II genotype was significantly higher in II genotype than those in ID or DD genotype (0.05 +/- 0.03 vs. 0.01 +/- 0.02, 0.01 +/- 0.03 respectively, P < 0.01). The post treatment plaque score (PS) in patients with II genotype was significantly reduced (4.85 +/- 2.51 vs. 3.90 +/- 2.36, P < 0.05). Multivariate linear regression analysis showed the baseline SBP, the decreased degree of SBP (DeltaSBP) and the II genotype were the major factors affecting the DeltaMIMT.</p><p><b>CONCLUSION</b>Hypertensive patients carrying II genotype ACE genotype are the best responders for the anti-atherosclerotic effects of amlodipine.</p>
