Abstract:
Objective:To explore the relationship between coronary heart disease (CHD)and silent brain infarction (SBI).Methods:A total of 430 patients who had received coronary angiography were enrolled,including 330 CHD patients and 100 non-CHD patients.According to complicated with SBI or not scanned by cranial MRI,CHD pa-tients were divided into CHD+SBI group (n=208)and CHD without SBI group (pure CHD group,n=122).Levels of high sensitive C reactive protein (hsCRP)and homocysteine (Hcy)were measured,and coronary artery score (CAS)and Gensini score (GS)were calculated in all patients.Results:Incidence rate of complicated SBI in CHD patients was significantly higher than that of non-CHD patients (63% vs.31%,P <0.01);compared with pure CHD group,there were significant rise in age [(60.79±9.65)years vs.(67.14±9.77)years],percentages of hy-pertension (41.0% vs.66.8%),hyperlipidemia (37.7% vs.55.8%)and levels of hsCRP [(3.92±2.17)g/L vs. (5.85±6.27)g/L],Hcy [(9.20±3.20)μmol/L vs.(10.54±4.25)μmol/L],CAS [(0.88±0.88)scores vs. (1.94±0.94)scores]and GS [(18.62±16.23)scores vs.(53.04±39.61)scores],and percentage of left anterior descending artery stenosis (25.4% vs.69.2%)in CHD+SBI group,P <0.01;Logistic regression analysis indicated that risk factors of SBI were age (OR=1.07,95%CI:1.032~1.108),hypertension history (OR=2.195,95%CI:1.104~4.366),Hcy (OR=1.088,95%CI:1.001~1.182),CAS (OR=1.776,95%CI:1.049~3.007)and GS (OR =1.039,95%CI:1.013~ 1.066),P <0.05 or <0.01. Conclusion:Incidence rate of SBI in CHD pa-tients is significantly higher than that of non-CHD patients;the more severe coronary artery disease is,the higher percentage of complicated SBI is.CAS and Gensini score abnormities suggest there may be SBI existence simultaneously.
