Abstract
Introduction: Age, sex and family history of cardiovascular disease (CVD) are non-modifiable risk factors of CVD in offspring. Our aim was to relate parental CVD (pCVD) to artery vessel-wall measurements in offspring.
Patients and methods: Offspring consisted of acute ischaemic stroke patients (15-60 years) and their partners. Young offspring was defined as ≤45 years old. Arterial wall changes were assessed as intima-media thickness of carotid and femoral arteries (cIMT/fIMT), abdominal aortic plaques (AAP), and ankle-arm index (AAI). Any offspring reported parental coronary artery disease (pCAD) and parental peripheral artery disease (pPAD). In addition, pCAD and pPAD were also verified by standardized questionnaires for living parents, or by medical records for deceased parents.
Results: Reported vs. verified pCVD was present for around 90% vs. 50% of parents. Reported pCAD/pPAD was positive for 227/67 offspring and verified pCAD/pPAD was positive for 148/36 offspring, respectively.
Reported and verified pCAD and pPAD were related to higher cIMT and fIMT. Reported and verified pCAD was also related to AAP and reported pPAD to AAI. The effect attenuated after adjusting for age, hypertension, dyslipidemia, diabetes mellitus and smoking. Among young offspring, reported pCAD was associated with higher cIMT and fIMT, even though the total number of young offspring was 4-fold lower compared to middle-aged offspring.
Conclusions: Parental CVD is related to artery wall changes in offspring, particularly in young offspring. Regarding CVD risk assessment, extensive parental verification of CVD might not be necessary as many young patients and partners seem to be well-orientated about their parental CVD. Primary prevention from young age should get more attention.
