Incidence of Cerebral Apoplexy in the Elderly Population in Longevity Areas in China and Its Correlation with Hypertension, Diabetes and Heart Disease / 现代检验医学杂志

ABSTRACT

Objective To study the incidence of stroke among elderly people in China's longevity area and its association with diseases such as hypertension,diabetes and heart disease.The differences in the following common hematological indicators in subjects with stroke and non-hypertension,diabetes,heart disease and stroke were studied:superoxide dismutase (SOD),malondialdehyde (MDA),hypersensitive c-reactive protein (hsCRP),albumin (propagated) glucose (GLU),cholesterol (CHO),triglyceride (TG),high-density lipoprotein cholesterol (HDLC),glycosylated serum protein (GSP) urea nitrogen (BUN),creatinine (CREA) and uric acid (UA).Methods Residents who participated in the project of biomedical research of aging population conducted in 2014 were selected from 8 longevity Areas in China.2 315 people aged 40 and over attended the study,including 22 aged 40 and over,238 aged 60 and over,490 aged 70 and over,629 aged 80 and over,518 aged 90 and over,418 aged 100 and over.Using the self-designed questionnaire to collect information about the characteristics of social demographics,the clinical doctors used the unified inspection tool to examine the subjects.The fasting blood samples were collected by vacuum tube at early morning.The contents of plasma SOD,MDA,hsCRP,ALB,GLU,CHO,TG,HDLC,GSP,BUN,CREA and UA were detected and compared among these elderly who were classified into different genders and different age groups and different healthy groups.Results The prevalence of high blood pressure,diabetes,heart disease and stroke increased with age,reaching a peak and then slowly decreasing.The age of peak was 90 ～ 99,60 ～ 69,70～ 79 and 80～ 89.The prevalence of hypertension was 71.62 ％ and 60.54 ％ respectively for stroke subjects and non-cerebral apoplexy subjects,and the difference was statistically significant.The prevalence of diabetes was 18.92％ and 11.35％ respectively,and the difference was statistically significant.The prevalence of heart disease was 20.98％ and 5.26％,respectively,and the difference was statistically significant.The rates of non-hypertension,non diabetic and non-heart disease were 4.73％ and 33.41％ respectively,and the difference was statistically significant.In the groups of Stroke subjects and Non-high blood pressure,nomdiabetic,non-heart disease subjects the following indicators were Compared,values of SOD were 55.76±8.27 and 57.16±8.00 U/ml respectively,the difference between groups were not statistically significant (t=0.341,P=0.053),values of MDA were 5.81 ± 3.82 and 5.67± 3.16 μmol/L respectively,the difference between groups were not statistically significant (t=0.329,P =0.661),values of hsCRP were 4.15 ± 12.33 and 2.94 ± 6.25 mg/L,respectively,the difference between groups were not statistically significant (t=0.026,P=0.080),values of ALB were 41.60±4.51 and 42.08±3.94 g/L respectively,the difference between groups were not statistically significant (t=0.032,P=0.194),values of ALB were 41.60 ± 4.51 and 42.08± 3.94 g/L respectively,the difference between groups were not statistically significant (t =0.032,P=0.194),values of ALB were 41.60 ± 4.51 and 42.08 ± 3.94 g/L respectively,the difference between groups were not statistically significant (t =0.032,P=0.194),values of GLU were 5.89 ± 2.67 and 4.90 ± 0.90 mmol/L respectively,the difference between groups showed statistically significant (t=0.000,P=0.000)),values of CHO were 4.81 ± 1.00 and 4.71±1.02 mmol/L respectively,the difference between groups were not statistically significant (t =0.670,P=0.318),values of TG were1.33±0.69 and 1.14±0.57 mmol/L respectively,the difference between groups showed statistically significant (t=0.012,P=0.000),values of HDLC were 1.29±0.35 and 1.41±0.40 mmol/L respectively,the difference between groups showed statistically significant (t=0.004,P=0.001),values of GSP were 259.10±60.90 and 246.75±24.52 μmol/L respectively,the difference between groups showed statistically significant (t =0.000,P =0.000),values of BUN were 6.84±± 3.53 and 6.62 ± 2.20 mmol/L respectively,the difference between groups were not statistically significant (t=0.110,P=0.338),values of CREA were 84.92 ± 33.00 and 80.14 ± 24.64 μmol/L respectively,the difference between groups showed statistically significant (t=0.013,P=0.044),values of UA were 296.73±91.34 and 288.12±80.47 μmol/L respectively,the difference between groups were not statistically significant (t=0.123,P=0.247).Conclusion Diabetes,hypertension,and heart disease are risk factors for stroke.Abnormal blood glucose and lipid metabolism:the increase of GLU,TG and the decrease of HDLC are important common biochemical index of stroke.Patients with cerebral apoplexy have certain renal impairment.
