Use of statins was significantly associated with a decreased risk of incidence or recurrence of AF in patients in sinus rhythm with a history of previous AF or undergoing cardiac surgery or after acute coronary syndrome
OBJECTIVES To improve the evaluation of the possible antiarrhythmic effect of statins , we performed a meta- analysis of r and omized trials with statins on the end point of incidence or recurrence of atrial fibrillation ( AF ) .
BACKGROUND The use of statins had been suggested to protect against AF in some clinical observational and experimental studies but has remained inadequately explored .
Effects of atorvastatin on systemic inflammatory response after coronary bypass surgery
Objectives : Systemic inflammatory response occurs frequently after coronary artery bypass surgery , and it is strongly correlated with the risk of postoperative morbidity and mortality . Recent studies demonstrate that treatment with statin is associated with a significant and marked decrease in inflammation-associated variables such as the C-reactive protein , cytokines , and adhesion molecules . Therefore , we investigated the effects of preoperative atorvastatin treatment on systemic inflammatory response and perioperative morbidity after cardiopulmonary bypass . Design : Double-blinded , placebo-controlled , r and omized study . Setting : University hospital . Patients : Forty patients were r and omized to treatment with atorvastatin ( 20 mg/day , group A , n = 20 ) or placebo ( group B , n = 20 ) 3 wks before surgery . Interventions : Three-week treatment by atorvastatin 20 mg/day . Measurement and Main Results : Postoperative serum levels of both interleukin-6 and interleukin-8 increased significantly over baseline , but the peak levels observed 4 hrs postoperatively were significantly lower in the atorvastatin group . In the same fashion , CD11b expression on neutrophils was significantly lower in the statin group at 4 and 24 hrs postoperatively . Finally , neutrophil-endothelial adhesion was significantly reduced in the statin patients compared with controls . The operation time , blood loss , need for inotropic support , intubation time , and length of intensive care unit or hospital stay did not differ significantly between the two groups . The systemic inflammatory response syndrome score on postoperative days 1 and 2 was comparable in both groups . Conclusions : Pretreatment with atorvastatin significantly reduces cytokine release and neutrophil adhesion to the venous endothelium in patients undergoing coronary artery bypass grafting with cardiopulmonary bypass
