Objective To explore the effect of amlodipine atorvastatin calcium tablets in the treatment of patients with hypertension and coronary heart disease complicated with carotid atherosclerosis. Methods From August 2013 to August 2017, 280 patients with hypertension and coronary heart disease complicated with carotid atherosclerosis in the Second People's Hospital of Ji'nan were selected, and they were divided into two groups by envelope randomization packet mode, with 140 cases in each group.The control group was treated with amlodipine benzenesulfonate.The observation group was treated with amlodipine atorvastatin calcium tablets.The incidence of adverse reactions, diastolic blood pressure(DBP) level, systolic blood pressure(SBP) level, total effective rate, hs-CRP, TC, TG, HDL-C, LDL-C, IMT, PV were compared between the two groups. Results There were no statistically significant differences in PV, IMT, SBP and DBP between the two groups (t=1.150, 0.861, 0.195, 0.637, all P>0.05). The incidence rate of adverse reactions(2.86%), DBP level[(78.95±3.11)mmHg], SBP level[(121.63±5.42)mmHg], total effective rate (96.43%), hs-CRP levels[(4.15±1.65)mg/L], TC level[(3.28±1.98)mmol/L], TG level[(1.22±0.34)mmol/L], HDL-C level[(1.98±0.75)mmol/L], LDL-C level[(1.33±0.54)mmol/L], IMT[(1.12±0.05)mm], PV[(0.11±0.03)cm3]in the observation group were better than those in the control group(χ2=22.630, t=15.839, 37.209, χ2=25.053, t=20.056, 7.381, 8.659, 15.110, 21.951, 15.665, 12.951, all P<0.05). Conclusion The effect of amlodipine atorvastatin calcium tablets in the treatment of patients with hypertension and coronary heart disease complicated with carotid atherosclerosis is remarkable.
