ABSTRACT
Objective By analyzing the mortality of patients with hypertension and cerebral infarction in different blood lipid stratification,the significance of blood lipid stratification management in the treatment of hypertension was clarified.Methods 604 patients with hypertension combined with cerebral infarction were divided into middle risk group (198 cases),high risk group (n=198) and extremely high risk group (n=208) and each group of different stratification according to the serum lipid HCY level,divided into H type hypertension group (HCY=10 μmol/L) and hypertension group ((HCY＜10 μmol/L group) and comparison of the 10 year mortality in each group.Results Comparison of mortality between H type hypertension group and simple hypertension group,among them,the difference between the two groups in middle risk group was statistically significant (x2 =5.095,P =0.024 205).The difference between the two groups in extremely high risk group was statistically significant (x2 =7.859,P=0.005 056).The difference between the two groups in high risk group was statistically significant (x2 =9.961,P=0.001 599).There was a significant difference in mortality between the groups with different blood lipids in simple hypertension group.Among the high-risk group and the middle risk group,the difference was statistically significant (x2=6.575,P=0.010 343),and there was significant difference between high risk group and high risk group (x2 =6.868,P=0.008 774).Comparison of mortality between different lipid levels in H type hypertension group,the difference was statistically significant.There was significant difference between the extremely high risk group and the high risk group (x2 =4.745,P=0.029 388) and there was significant difference between the high risk group and the middle risk group (x2 =11.668,P=0.000 636).Conclusion Hyperlipidemia,especially high LDL and high HCY are the main causes of death in patients with hypertension complicated with cerebral infarction,the clinical use of blood lipid levels can reduce the level of LDL and reduce the mortality of patients by strengthening the control of HCY level.Improve the survival rate of patients.
ABSTRACT
Objective To investigate the correlation between non high density lipoprotein cholesterol (non-HLD-C)and cardi-ac function in patients with coronary heart disease (heart disease cardiac,CHD).Methods 162 patients with CHD were se-lected as the experimental group of CHD,100 cases of healthy physical examination qualified as the normal control group. CHD experimental group was divided into mild impairment group and severe impairment group according to the degree of impairment of the heart function.The mild impairment group include I and II levels of cardiac function classification and the severe impairment group included III and IV levels of cardiac function classification.To measure separately total cholesterol (TC),triglyceride (TG),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),and to calculate the content of non high density lipoprotein cholesterol (non-HDL-C).To compare the differences between CHD ex-perimental group and normal control group,and the correlation between different indexes of blood lipid and the degree of loss of cardiac function.Results The serum levels of non-HDL-C,TG and LDL in the Cardiac function in mild damage group of the CHD experimental group were significantly higher than those in the normal control group,and there were statistically significant differences between the two groups(t=2.438,2.887,5.253,P<0.05).The serum levels of non-HDL-C,TG and LDL in the severe heart function impairment group of the CHD experimental group were significantly higher than those in the normal control group,and there were statistically significant differences between the two groups (t=2.438,2.887,5.253,P<0.05).The serum level of HDL in the cardiac function in mild damage group of the CHD experimental group was significantly lower than that in the normal control group (t=-3.132,P<0.05).The serum level of HDL in the severe heart function impairment group of the CHD experimental group was significantly lower than that in the normal control group (t=-6.028,P<0.05).In the CHD group,only the serum level of TC in the severe impairment group was signifi-cantly different from that in the control group (t=3.278,P<0.05).The serum levels of non-HDL-C,TG,LDL of mild im-pairment of cardiac function in the CHD experimental group were significantly different from the serum levels of the severe impairment group (t=2.051,2.057,2.281,P<0.05).Logistic regression analysed that the OR value of serum non-HDL-C in CHD group was slightly lower than that of LDL,and significantly higher than TC and TG.With the increase of the degree of cardiac function,the value of OR increased significantly.Conclusion Serum non-HDL-C had a positive correlation with severity of CHD.To a certain extent,it can reflect the severity of CHD and is an important reference index for clinical diag-nosis and treatment of CHD.
