Abstract: Objective To assess characteristics of coronary artery lesions and risk factors of coronary heart disease (CHD) in young people with coronary arteriography.Methods 192 patients with CHD diagnosed by coronary arteriography were divided into the young group (91 cases, 25—40 years old) and senile group (101 cases, 41—84 years old). Characteristics of coronary artery lesions and risk factors of CHD of two groups were analyzed, and risk factors were especially tested with logistic regression.Results Coronary artery lesions in the young group were characterized in most patients by singles vessel lesion (64%), while by multi vessels lesion (71%) in the senile group. Multiple logistic regression analysis showed that risk factors such as male, smoking, hyperlipemia, family history and increassed C-reactive protein (CRP) were highly related with CHD(P<0.01).Conclusion Single vessel lesion is a feature of young patients with CHD, and independent and related risk factors of CHD in the young group are male, smoking, hyperlipemia, CHD family history and CRP.
