The aim of this study was to investigate the efficacy of berberine administration on POAF.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods:<\/jats:title>\n            <jats:p>We conducted a randomized, double-blind, placebo-controlled trial with patients who underwent isolated coronary artery bypass grafting in China to study the impact of oral berberine on the incidence of POAF. A total of 200 patients who underwent coronary artery bypass grafting were randomized into the berberine group (n=100) and the placebo group (n=100).

Secondary outcomes included clinical outcomes, POAF burden, intestinal endotoxin, and serum inflammatory biomarker levels. The POAF incidence was reduced from 35% to 20% under berberine treatment (hazard ratio, 0.5 [95% CI, 0.29\u20130.78];\n              <jats:italic>P<\/jats:italic>\n              =0.0143). Perioperative mortality and morbidity did not differ between the 2 groups. POAF burden and the dose of amiodarone were significantly reduced in the berberine group. Oral berberine significantly decreased lipopolysaccharide, CRP (C-reactive protein), and IL (interleukin)-6 levels. Elevated lipopolysaccharide after surgery has been associated with POAF.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>Our results showed that administration of berberine may be effective for reducing the occurrence of POAF after coronary artery bypass grafting.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Registration:<\/jats:title>\n            <jats:p>\n              URL:\n              <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/www.chictr.org.cn\">https:\/\/www.chictr.org.cn<\/jats:ext-link>\n              ;
