Inflammation is associated with atrial fibrillation (AF), and peroxisome proliferator-activated receptor-gamma (PPARγ) agonists have anti-inflammatory properties. We tested whether pioglitazone reduced AF recurrence after electrical cardioversion (EC) by modifying systemic inflammation. In this randomized and prospective trial, patients with persistent AF and type 2 diabetes mellitus were randomized into a pioglitazone group (n=48) or a control group (n=49) before EC. Treatment was continued for 3 months or until AF recurred. Serum inflammatory markers [high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α)] were measured at baseline and follow-up. During the 3-month follow-up, AF recurred in 22 (45.8%) patients of the pioglitazone-treated and 24 (49.0%) patients of the control group (P=0.756). However, the 3 inflammatory markers were significantly lowered with pioglitazone treatment during follow-up. Cox proportional hazards regression models showed that the predictors of recurrence included AF history (relative risk RR 1.002, 95% CI 1.003-1.061, P =0.037) and the left atrial diameter (RR 1.131, 95% CI 1.029-1.242, P = 0.010). In conclusion, while reducing some inflammatory markers, the PPARγ agonist pioglitazone did not affect the recurrence of AF after EC.
炎症与心房颤动(AF)有关,过氧化物酶体增殖物激活受体-γ(PPARγ)激动剂具有抗炎作用。我们测试了吡格列酮是否通过改变全身炎症来减少电复律(EC)后的 AF 复发。在这项随机前瞻性试验中,患有持续性 AF 和 2 型糖尿病的患者在 EC 前被随机分为吡格列酮组(n=48)或对照组(n=49)。治疗持续 3 个月或直至 AF 复发。在基线和随访时测量血清炎症标志物[高敏 C 反应蛋白(hs-CRP)、白细胞介素-6(IL-6)和肿瘤坏死因子-α(TNF-α)]。在 3 个月的随访期间,吡格列酮治疗组有 22 名(45.8%)患者和对照组有 24 名(49.0%)患者发生 AF 复发(P=0.756)。然而,在随访期间,吡格列酮治疗可显著降低 3 种炎症标志物。Cox 比例风险回归模型显示,复发的预测因素包括 AF 病史(相对风险 RR 1.002,95%CI 1.003-1.061,P=0.037)和左心房直径(RR 1.131,95%CI 1.029-1.242,P=0.010)。总之,虽然 PPARγ 激动剂吡格列酮降低了一些炎症标志物,但对 EC 后 AF 的复发没有影响。
