ABSTRACT
Risk assessment for fast growing burden of cardiovascular diseases is very important and difficult. As a response to this challenge, in particular, genetic risk factors which potentially modify risk, we conducted a survey of primary data registry of Shiraz Heart Study on integration and application of family history data in prevention of cardiovascular disorders. This study is a longitudinal cohort project to be extended from subpopulations of different job groups to the community. Parental family history of MI, diabetes mellitus [DM], hyperlipidemia [HPL], hypertension [HTN] was reported more frequently among females than males. Histories of MI, DM, HPL, and HTN in both parents were respectively positive in 2.6%, 2%, 4.6%, and 7.9% of the participants. Odd ratios [OR] for risk of MI from family history of MI were 2.7; risk of DM from family history of DM 4.5; risk of HPL from family history of HPL 2.04; and risk of HTN from family history HTN 4.7. Also, family history of MI modifies risk of HPL [OR=1.7, P<0.0001]; and family history of DM modifies risk of HPL [OR=2.04, P<0.0001]. Our primary result shows potent application of family history data in risk assessment of cardiovascular outcome. In particular, HTN appears as a silent and leading risk modifier. In regard to the course of continuing Shiraz Heart Study integration of family history of risk factors crucial in public health we suggest to adopt a network of electronic health records from the [Health House] to the [Heart House]
