应用清除自由基药物治疗急性脑梗塞临床观察

脑梗塞超过一定时间后,恢复血液再灌流可加重病情,使缺血进一步发展并达到高峰.现在证实脑梗塞再灌流性损害,是自由基连锁反应激化所造成的,所以,清除自由基,切断自由基连锁反应,可能是治疗脑梗塞的首要条件.我们自1992年10月始,对62例急性脑梗塞病人随机分为清除自由基治疗与传统治疗两组进行疗效对比.1 临床资料1.1 一般资料:62例患者均按1986年中华医学会第二次全国脑血管病学术会制定的各类脑血管病诊断要点确诊,并经CT证实.年龄最小39岁,最大84岁.梗塞部位在底节和侧脑室体旁48例,内囊后支8例,小脑梗塞3例,颞顶枕叶大面积梗塞3例.病程在7天以内,分为清除自由基治疗组和传统治疗组各31例.治疗前均查CT、心电图、血糖、血脂.     

口服卡托普利和单硝酸异山梨醇对急性心梗室性心律失常的效果

口服卡托普利和单硝酸异山梨醇对急性心梗室性心律失常的效果动物实验和临床研究均表明，增加心室壁张力可使室性心律失常的发生率增加，降低室壁张力则起相反的效果。为了评估口服血管扩张剂对急性心肌梗塞（ＡＭＩ），室性心律失常的治疗作用，本文采用随机分组安慰剂对...

曲美他嗪联合阿托伐他汀治疗原发性高血压伴阵发性心房颤动的疗效观察

Objective To study the efficacy of trimctazidine combined with atorvastatin for primary hypertension with paroxysmal auricular fibrillation,and its effects on LAD and CRP. Methods 160 patients of pri-mary hypertension with paroxysmal auricular fibrillation were randomly divided into 4 groups. Forty patients were treated with amiodarone (control group),600 mg/d for the first week,400 mg/d for the second week and 200 mg/d later;40 patients were treated with atorvastatin (20 mg/d,3 times per day) in addition to amiodarone (the atorvasat-in group);40 patients were treated with trimetazidine (20 mg/d,3 times per day) in addition to armiodarone (the trimetazidine group);40 patients were treated with combination of trimetazidine and atorvastatin in addition to amiod-atone (the combination group),and the dose was the same as the above groups. The treatment was started within 24 hours of recovering from paroxysmal auricular fibrillation and lasted for 1 year. Results After 1 year there was 1 pa-the control group,and 62.5% (25/40) for the atorvasatin group,64.1% (25/39) for the trimetazidine group,and 84.6% (33/39) for the combination group. Compared to the control group,the effective rate of the 3 treatment groups were all significantly higher (X2=4.56、5.13、17.55,P<0.05). The effective rate of the combination group was significantly higher than that of the atorvasatin group and the trimetazidine group (X2=4.95、4.30,P<0.05),and there was no significant difference of effective rate between the atorvasatin group and the trimetazidine group(X2= >0.05). After treatment LAD was (40.96+1.81) mm in the control group,(38.65±1.90) mm in the atorvasatin group,(39.15±1.85)mm in the trimetazidine group,and (37.22±1.74) mm in the combination group. LAD of the 3 treatment groups were all significantly different from the control group(F=3.42,P<0.05). LAD of the combina-tion group was significantly smaller than that of the atorvasatin group and the trimetazidine group (P<0.05),and there was no significant difference of the LAD between the atorvasatin group and the trimetazidine group(P>0.05). There was no significant difference between the 4 groups on CRP before treatment (F=0.96,P>0.05). After treat-ment CRP was (8.85±1.45) mg/L in the control group,(5.96±1.26) mg/L in the atorvasatin group,(6.81± 1.37) mg/L in the trimetazidine group,and (3.75±1.15) mg/L in the combination group. CRP of the 3 treatment groups were all significantly different from the control group (F=3.63,P<0.05). CRP of the combination group was significantly lower than that of the atorvasatin group and the trimetazidine group (P<0.05),and there was no signif-icant difference of CRP between the atorvasatin group and the trimetazidine group (P>0.05). Conclusion The treatment with trmetazidine combined with atorvastatin could prevent recurrence of paroxysmal auricular fibrillation though anti-inflammatory and inhibiting the remodeling of left atrial.
