RESUMO
Objective To study the prevalence and related risk factors of type 2 diabetes with coronary heart disease(CHD) and cerebral infarction after long-term treatment.Methods Two hundred and eighty-five patients with type 2 diabetes who had a hospitalization interval for four to twelve years between the first and second hospital stays were included in group A.Among them,85 patients (about 4 to 7 years) with a hospitalization interval about 5 years (4 to 7 years) between the first and second hospital stays(group B).100 patients with a hospitalization interval about 10 years (8 to 12 years) between the first and second hospital stays(group C).Blood pressure,blood glucose,HbA1c,blood lipids,myocardial enzymology,electrocardiogram,coronary angiography,cranial CT or MRI were tecorded.The prevalence of CHD and cerebral infarction were compare,regression analysis was conducted between coronary heart disease,cerebral infarction and the risk factors.Results DBP,FBG,PBG2h,TC,LDL-C of the second hospitalization were significantly lower than those of the first hospitalization.The morbidity of CHD and cerebral infarction increased along with the extension of the course.The morbidity of cerebral infarction in CHD patients were significantly higher than those in non-CHD patients with the interval about 10 years.Logistic regression analysis proved that age was risk factor and HDL-C was protective factor of CHD,SBP,FBG were risk factors of cerebral infarction.Conclusion The morbidity of CHD and cerebral infarction increased along with the extension of the course and there were significantly relationship between CHD and cerebral infarction in T2DM patients after about 10 years treatment.
