Abstract:
OBJECTIVETo investigate the relationship between angiotensin converting enzyme (ACE) gene and exercise-induced silent myocardial ischemia (SI) in patients with type 2 diabetes mellitus.
METHODSOne hundred and eight patients suffering from type 2 diabetes mellitus with normal rest electrocardiograph and 50 healthy individuals were selected randomly. SI was diagnosed with treadmill exercise test and ACE genotypes were detected with PCR.
RESULTS(1) The control group and type 2 diabetes mellitus group had similar distribution of ACE genotypes and alleles (P>0.05). Compared with the non-SI group, the SI group had significantly higher ACE D allele prevalence (Chi-square=4.501, P<0.05); however, the two groups had similar prevalence of ACE genotypes (P>0.05). (2) There were no significant differences in clinical characteristics and serum lipoproteins among the three ACE genotypes (II, DD,ID) of type 2 diabetes mellitus (P>0.05). (3) The prevalence of SI in DD group was found to be 68.2%, which was significantly higher than that in II genotype group (39.5%, Chi-square=4.593, P<0.05).
CONCLUSIONACE D allele increases the risk of SI in type 2 diabetes mellitus.
