Abstract:
Objective Through clinical observation and research with persistent atrial fibrillation in patients with blood-brain natriuretic peptide ( BNP) level change detection renin, angiotensin Ⅱ, aldosterone, analyze their data, investigate persistent atrial fibrillation ( PAF ) serum brain natriuretic hormone levels change and the relationship between the renin-angiotensin-aldosterone system (RAAS).Methods 80 patients with coronary artery disease in our hospital from December 2013 to October 2015 were selected, randomly divided into experimental principle PAF group (40 cases) and control group ( patients in sinus rhythm,with 40 cases) , BNP, renin, angiotensinⅡ, aldosterone levels were measured in two groups, and left atrial diameter (LAD) measurements.Results Under the same condition of cardiac function, the blood BNP concentration in PAF group was higher than that in control group (P <0.05).The results of the linear regression analysis showed that the correlation coefficient of blood BNP level and AngII concentration in PAF group was 0.301, the correlation coefficient of blood BNP level and LAD indicators in PAF group was 0.373, the concentrations of BNP and RAAS were positively correlated with LVMI, the differences were statistically significant (P<0.05), the blood BNP level was closely related to the level of RAAS in the PAF group (P<0.05).Conclusion Blood BNP concentration was significantly higher in patients with PAF and blood BNP concentration is closely related with the RAAS, LAD indicators, and a positive correlation.
