A comprehensive case-control study was conducted in an Italian region in order to compare the influence of family history of cardiovascular events, socioeconomic factors, social networks, and their joint associations with major risk factors, on the risk, of myocardial infarction (MI), unstable angina (UA) and ischemic stroke (IS).
A total of 513 patients with MI, 178 with UA, 237 with IS, and 928 hospitalised controls were recruited.
The odds ratio (OR) of MI for two or more relatives with a positive history of MI was 3.6 (95% CI : 1.8-7.3).
Family history of MI was predictive for UA (OR=5.8 ; 95% CI : 1.2-28.7), but not for IS.
A family history of stroke was more associated with the risk of MI than of IS.
After adjustment for known risk factors, the OR of MI for more educated people was 2.1 (1.3-3.6) compared with less-educated people.
Large family size seemed to be protective for MI.
The effect of major risk factors on MI ranged from additive (diabetes) to multiplicative jointly with high education and family history of MI.
A family history of stroke increased IS risk threefold jointly with smoking and hyperlipidemia, and eightfold with diabetes.
Besides a family history of MI and IS, in this community a higher educational status seems to better identify groups at increased risk of MI. (...)
