The current situation of traditional risk factors in acute myocardial infarction patients with different age / 中国医师进修杂志

ABSTRACT

Objective To analyze the current situation of traditional risk factors in acute myocardial infarction (AMI) patients with different age,and to explore the impact of different risk factors on AMI.Methods The personal clinical characteristics of 682 hospitalized AMI patients in CCU were recorded from October 2003 to October 2010 with a retrospective cohort study.The effect of smoking,hyperlipidemia,diabetes and hypertension on AMI was observed.Results Six hundred and thirteen patients were enrolled in the end,43 cases in young group,216 cases in middle age group,234 cases in older age group,120cases in old-old age group.(1) Compared with that in middle age group,older age group and old-old age group,the ratio of smoking and hyperlipidemia in young group was significantly higher(P ＜ 0.0125 or ＜ 0.001).The ratio of smoking in middle age group was significantly higher than that in older age group(P ＜ 0.001),and the ratio of hyperlipidemia between two groups had no significant difference (P ＞ 0.0125).The ratio of smoking and hyperlipidemia was significantly higher in middle age group compared with that in old-old age group(P＜0.001 or ＜ 0.0125).(2) The average age in smoking patients with AMI was (56.84 ± 13.00) years,which was significantly younger than that in non-smoking patients[(74.29 ± 10.57) years] (P ＜ 0.01).The average age in patients with hyperlipidemia suffering from AMI was significantly younger than that in patients with normal lipid level patients [(62.92 ± 15.04) years vs.(68.63 ± 13.93) years] (P ＜ 0.01).Conclusions Smoking and hyperlipidemia,especially smoking plays an important role in inducing AMI in young and middle age.Smoking cessation and lipid-lowering therapy is vital for reducing the occurrence of AMI in young and middle age.
