Objective To investigate the effects of rosuvastatin combined with amiodarone on ventricular remodeling, electrocardiogram P wave dispersion, peripheral blood Apelin-13 and transforming growth factor (TGF)-β1 in patients with paroxysmal atrial fibrillation (PAF). Methods From April 2017 to April 2018, 116 PAF patients admitted to the First Affiliated Hospital of Xinxiang Medical College were divided into treatment group and control group by random number table method, with 58 cases in each group. The control group was given oral amiodarone. On this basis, treatment group was additionally given oral rosuvastatin. The measurement data such as left atrial diameter (LAD), left ventricular ejection fraction (LVEF), electrocardiogram P wave dispersion, peripheral blood Apelin-13 and TGF-β1 before treatment and 12 weeks after treatment were obtained. The effective rate and prognosis of sinus rhythm maintenance 3 months, 6 months and 12 months after treatment were followed up. Results After 12 weeks of treatment, LAD in treatment group was significantly lower than that in control group, LVEF was significantly higher than that in control group, P wave dispersion was significantly lower than that in control group, and serum apelin-13 was significantly higher than that in control group, TGF-β1 was significantly lower than that in control group, and all the differences were statistically significant (P < 0.05). LAD, LVEF, P wave dispersion, apelin-13 and TGF-β1 in treatment group were higher than those in control group, and the differences were statistically significant (P < 0.05). All patients were followed up for at least 1 year after treatment, with follow-up rate of 100%. The response rate of sinus rhythm maintenance 3 months, 6 months and 12 months after treatment in treatment group was 94.83%, 87.93% and 81.03%, respectively, all significantly higher than that in control group (82.76%, 72.14% and 63.79%) (P<0.05). The proportion of patients conversing to persistent AF in treatment group was significantly lower than that in control group (3.45% vs 13.79%) (P<0.05). There was no significant difference in the proportion of patients conversing to permanent atrial fibrillation (AF) between the two groups (P>0.05). Conclusions Rosuvastatin combined with amiodarone can effectively improve ventricular remodeling, electrocardiogram P wave dispersion, peripheral blood Apelin-13 and TGF-β1 levels in PAF patients, thus helping maintain sinus rhythm and improve clinical outcomes. |
