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.%目的 通过分析高血压并发脑梗死患者在不同血脂分层下病死率的情况,阐明血脂分层管理在高血压治疗中的意义.方法 604例高血压并发脑梗死患者根据血脂分层管理的要求分为中危组(198例),高危组(198例)和极高危组(208例),并将各组根据血清中HCY(同型半胱氨酸)水平,分为H型高血压亚组(HCY＜10 μmol/L)与单纯高血压亚组(HCY＜10μmol/L),比较各组患者10年病死率的情况.结果 H型高血压亚组与单纯高血压亚组间病死率比较,其中中危组中两亚组间比较,差异有统计学意义(x2=5.095,P=0.024 205),极高危组中两亚组间比较,差异有统计学意义(x2=7.859,P=0.005 056),高危组中两亚组间比较,差异有统计学意义(x2=9.961,P=0.001 599).单纯高血压亚组中不同血脂分层组间病死率比较,其中高危组与中危组组间比较,差异有统计学意义(x2=6.575,P=0.010 343),极高危组与高危组组间比较,差异有统计学意义(x2 =6.868,P=0.008 774).H型高血压亚组中组间病死率比较,其中极高危组与高危组组间比较,差异有统计学意义(x2 =4.745,P=0.029 388),高危组与中危组组间比较,差异有统计学意义(x2=11.668,P=0.000 636).结论 高血脂尤其是高LDL以及高HCY是引起高血压并发脑梗死患者死亡的重要原因,临床可通过血脂分层管理有指导性地降低LDL水平以及通过加强对HCY水平的控制来降低患者病死率,提高患者生存率.
