Abstract:
OBJECTIVE:To explore the effect of olmesartan on NT-proBNP and high-sensitive C- reactive protein(hs-CRP) and left atrial diameter (LAD) in elderly hypertensive patients with paroxysmal atrial fibrillation (PAF). METHODS:188 cases of elderly hypertensive patients with PAF from May 2011 to May 2013 were divided into control group(n=94)and observation group (n=94),both groups received the treatment of amiodarone,observation group were additionally given olmesartan on the basis of conventional treatment,the treatment cycle was 12 months in two groups. NT-proBNP,hs-CRP,LAD changes and atri-al fibrillation(AF)recurrence were compared between 2 groups before(T0)and after 1 month(T1),3 months(T2),6 months (T3)and 12 months(T4)treatment;related factors for recurrence of atrial fibrillation were analyzed. RESULTS:NT-proBNP and hs-CRP in observation group were lower than control group at T3-T4,with significant difference(P<0.05);LAD improvement in observation group was better than control group,with significant difference (P<0.05). After treatment,the decent range of NT-proBNP and hs-CRP in observation group were higher than that control group,with significant difference(P<0.05);AF re-currence in observation group were lower than control group at T3-T4,with significant difference(P<0.05);Multiple stepwise re-gression analysis showed that NT-proBNP and hs-CRP were positively related with LAD,with significant difference (P<0.05);multi-factor logistic regression analysis showed that the NT-proBNP level,hs-CRP,LAD were positively correlated with AF re-currence,NT-proBNP drop and hs-CRP drop were negatively correlated with AF recurrence. CONCLUSIONS:Serum NT-proB-NP and hs-CRP levels are closely related to LAD and AF recurrence in elderly hypertensive patients with PAF,and olmesartan can decrease the plasma NT- proBNP CRP levels,reduce inflammation response and improve left atrial remodeling so as to re-duce the AF recurrence.
