Abstract:Objective To investigate the effects of different dose of Atorvastatin on elderly patients with unstable carotid plaques complicated ischemic stroke in perioperative period, and the effects on stress and carotid plaque stability. Methods Seventy-six elderly patients with fractures admitted to Jiangjin District Central Hospital in Chongqing City from January 2015 to April 2017 were selected and they were divided into observation group and control group according to the random number table method, with 38 cases in each group. The control group was given Atorvastatin 10 mg/d oral and the observation group was given Atorvastatin 20 mg/d oral. The treating course was 6 months. The clinical efficacy, stress response index and carotid plaque stability were observed in the two groups. Results After treatment, the total clinical effective rate of the observation group was higher than that of the control group, and the difference was statistically significant (P < 0.05). After 4 weeks of treatment, the levels of malondialdehyde and low density lipoprotein in the observation group was significantly lower than those of the control group, the difference was statistically significant (P < 0.05). After 6 months of treatment, scores of the scale of the National Institutes of Health of the United States (NIHSS), arterial plaque area and carotid artery intima thickness (Crouse) scores were significantly lower in the observation group than those in the control group, the difference was statistically significant (P < 0.05). There was no significant difference in the adverse reaction between the two groups (P > 0.05). Conclusion Large dose of Atorvastatin in the treatment of elderly fracture patients with unstable carotid artery atherosclerotic plaques complicated ischemic stroke in perioperative period has a satisfatory curative effect, which can effectively reduce the injury of oxidative stress, reduce the area of plaque, and it is safe and reliable.
