ABSTRACT
AIM:
Healthy young subjects with parental history of premature myocardial infarction (PHPMI) might constitute a privileged population for the study of genetic risk markers (GRM) for atherosclerosis. Aim of this study was to evaluate which, if any, GRM atherosclerosis-associated in previous studies has increased prevalence in a selected population.METHODS:
Twenty-four healthy young subjects (12 males and 12 females; mean age 18.0±8.0 years) with PHPMI and 24 age- (±1 year), sex-matched healthy subjects without PHPMI were enrolled in the study. They underwent 1) fasting measurement of lipid profile, resting blood pressure and body mass index; 2) high resolution B-mode ultrasonographic evaluation of common carotid artery intima-media thickness (IMT); 3) evaluation of Single Nucleotide Polymorphisms (SNPs) for six candidate genes associated with preclinical atherosclerosis.RESULTS:
Compared to controls, subjects with PHPMI had increased IMT of common carotid arteries (mean of combined sites 0.535±0.171 mm versus 0.432± 0.133 mm in controls, P=0.017). Offspring of coronary patients showed an increased prevalence of the unfavourable chemochine (C-X-C motif) ligand 12 (CXCL12) SNP risk genotype (P=0.047).CONCLUSION:
In healthy young subjects with PHPMI there is an increased prevalence of the unfavorable CXCL12 SNP risk genotype.
