RESUMO
<p><b>OBJECTIVE</b>To investigate the relationship of angiotensin I-converting enzyme (ACE) gene polymorphism to diabetic retinopathy and diabetes myocardial infarction.</p><p><b>METHODS</b>ACE insertion/deletion(I/D) polymorphism was determined by PCR.</p><p><b>RESULTS</b>No evidence showed that ACE gene was associated with diabetic retinopathy. By comparison of the type 2 diabetes patients with myocardial infarction versus those without-myocardial infarction, it was found that the frequencies of homozygote DD (41.2% versus 33.2%) and of allele D (64.7% versus 55.0%) increased remarkably; the difference was statistically significant (P<0.05).</p><p><b>CONCLUSION</b>Allele D(RR=1.50) and genotype DD(RR=1.33) seemed to be a genetic risk factor for type 2 diabetes myocardial infarction.</p>
