    Abstract:
    AIMS: The present study was designed to test whether early carotid structural changes are demonstrable (by high resolution B-mode ultrasound) in children, adolescents and young adults with a history of premature parental myocardial infarction. METHODS AND RESULTS: One hundred and fourteen healthy young (5 to 30 years) subjects with a parental history of premature myocardial infarction and 114 age- and sex-matched control subjects were enrolled in the study. They were divided into two age groups: children and adolescents (age 5 to 18 years) (54 individuals with a parental history of premature myocardial infarction and their control subjects; mean age 12.8+/-3.8 years) and young adults (age 19 to 30 years) (60 individuals with a parental history and their controls; mean age 23.8+/-3.3 years). All subjects underwent high resolution B-mode ultrasonographic evaluation of common carotid artery intima-media thickness. Lipid profile, resting blood pressure, body mass index and smoking status were also evaluated. In both age groups, compared to controls, subjects with a parental history of premature myocardial infarction had increased intima-media thickness of common carotid arteries (mean of combined sites: age 5-18 years: 0.45+/-0.076 mm vs 0.40+/-0.066 mm in controls, P=0.008; age 19-30 years: 0.48+/-0.077 mm vs 0.45+/-0.078 mm in controls,P =0.007) Offspring of coronary patients showed an unfavourable lipid profile, however, the association between a parental history of premature myocardial infarction and carotid intima-media thickness was independent of lipids, apolipoproteins and other traditional risk factors. CONCLUSIONS: Vascular structural changes associated with a parental history of premature myocardial infarction are already detectable in childhood and adolescence and occur independently of several traditional cardiovascular risk factors.
