Objective To evaluate the efficacy of preoperative low-dose oral amiodarone for the prevention of atrial fibrillation （AF） after off-pump coronary artery bypass grafting （OPCAB） in patients older than 70 years. Methods A total of 156 patients older than 70 years who underwent OPCAB in Qingdao Fuwai Cardiovascular Disease Hospital from January 2011 to June 2012 were included in this prospective，double-blind and placebo controlled study. Preoperatively，all the 156 patients were randomly divided into amiodarone group and control group. In the amiodarone group，there were 80 patients including 38 male and 42 female patients who were given oral amiodarone （trade name： Cordarone） 200 mg，three times a day，3-5 days before surgery，and amiodarone was stopped on the OPCAB day and postoperatively. Preoperative duration of amiodarone intake was 4.0±1.2 days，and total amiodarone dosage was 2.6±0.5 g. In the control group，there were 76 patients including 35 male and 41 female patients who were given oral placebo as the same medication schedule，and preoperative duration of placebo intake was 4.0±1.4 days. Operation time，graft number，postoperative AF incidence，AF duration，hospital stay and readmission rate for cardiovascular events within 6 postoperative months were compared between the two groups. Results There was no in-hospital death in either group. There was no statistical difference in graft number，operation time，AF duration of patients who had postoperative AF，or postoperative hospital stay between the two groups. Postoperative AF incidence of the amiodarone group was significantly lower than that of the control group ［18.7% （15/80） vs. 34.2% （26/76），P=0.028］. Seventy-three patients in the amiodarone group （91.3%） and 66 patients in the control group （86.8%） were followed up for 8-24 months. During follow-up，2 patients in the amiodarone group died of acute myocardial infarction and cerebral hemorrhage respectively. There was no statistical difference in readmission rate for cardiovascular events within 6 postoperative months between the 2 groups ［6.8% （5/73） vs. 6.1% （4/66），P=0.860］ .Conclusion Preoperative low-dose oral amiodarone can significantly reduce the incidence of postoperative AF in patients older than 70 years undergoing OPCAB.
Objective To evaluate the efficacy and safety of Shen Song Yang Xin Capsule for cardiac arrhythmia. Methods Randomized controlled trials (RCTs) were searched from the following electronic databases: WanFang, CNKI, CBM, VIP, PubMed, and The Cochrane Library. Quality assessment and data extraction were conducted by two reviewers independently. Disagreement was resolved through discussion. All data were analyzed by using RevMan 5.0 software. Results Thirteen studies involving 1896 participants were included. The results of meta-analyses showed that compared with the control group, a) efficacy: Shen Song Yang Xin Capsule was superior to mexiletine (OR=2.96, 95%CI 1.79 to 4.87), and propafenone (OR=2.41, 95%CI 1.60 to 3.62), but was not superior to miodarone (OR=1.25, 95%CI 0.88 to 1.71); b) safety: Shen Song Yang Xin Capsule was superior to propafenone and miodarone in reducing the incidence of cardiac arrhythmia (OR=0.06, 95%CI 0.01 to 0.35; OR=0.05, 95%CI 0.02 to 0.17), but no significant difference was found between the two groups in incidence of gastrointestinal adverse reactions. Conclusion Based on the current studies, Shen Song Yang Xin Capsule is not inferior to the commonly-used anti-arrhythmic medicine at present. It has lower incidence of cardiac arrhythmia, and has no significant difference in the incidence of gastrointestinal adverse reactions compared with western drugs. For the quality restrictions of the included studies, more double blind RCTs with high quality are required to further assess the effects.

Methods A patient with dilated cardiomyopathy was admitted in October, 2010. During the procedure, the use of amiodarone hydrochloride injection made the patient suffer from liver and kidney dysfunction. We retrieved the literatures about liver and kidney toxicity of amiodarone from CNKI, Pubmed, and Embase (from the establishment of the databases to November 2011). We also ssessed the possibility of the adverse drug reaction, discussed the mechanism of amiodarone-induced hepatic insufficiency. Results According to the literature, There was a great possibility of hepatic insufficiency induced by amiodarone, and the total score of the Naranjo probability score was 7. Conclusion It is important to pay more attention to the pharmaceutical care of amidarone to timely recognize and effectively prevent or treat hepatic and renal insufficiency induced by intravenous injection with amiodarone.
ObjectiveTo investigate the effect of 5% dextrose intravenous infusion for phlebitis caused by amiodarone.
MethodsA total of 136 patients treated in our hospital between June 2011 and March 2012 were randomly assigned into control group with 63 patients and intervention group with 73 patients. The control group was administrated 600 mg amiodarone with 15 drops/minute intravenous injection once daily, for 3 days, while for the intervention group patients, we added 5% dextrose solution infusion in the same channel at the same time.
ResultsPhlebitis occurred in 22 patients (34.9%) in the control group, while the intervention group had only 11 (15.0%) (χ2=7.252,P=0.007).
ConclusionInfusion of 5% dextrose solution can significantly reduce the occurrence of phlebitis caused by amiodarone.

Methods:One hundred and six patients of AF with CHF caused by a variety of reasons were randomly divided into treatment group and control group according to hospitalized order.The two groups were treated with the same antiCHF therapy,the treatment group was treated with loaded intravenous amiodarone 150 mg;and then dripped to 1 000 μg/min for 6 hours, dripped to 500 μg/min for 18 hours. United with oral amiodarone by amiodarone tablets with 0.2 g,3 time/day a week,further 0.2 g,2 times/day a week,later 0.2 g,1 times/day to the end.The end of followup time was 12 months. Results:In treatment group,53 cases with amiodarone therapy can significantly increase the effectives of antiarrhythmic, improve the rate and heart failure rehospitalization.42/53 patients reversed to sinus rhythm. Conclusion:The results showed it is effective and safe united with intravenous amiodarone and oral amiodarone in treatment of atrial fibrillation with organic heart disease.
ObjectiveTo systematically review the efficacy of irbesartan combined with amiodarone versus amiodarone alone for paroxysmal atrial fibrillation.
MethodsWe electronically searched databases including PubMed, CENTRAL, EMbase, VIP, CNKI and WanFang Data to collect randomized controlled trials (RCTs) about irbesartan combined with amiodarone versus amiodarone alone in the treatment of paroxysmal atrial fibrillation from 2000 to 2014. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies. Then, meta-analysis was performed using RevMan 5.2 software.
ResultsA total of nine studies involving 998 patients were included. The results of meta-analysis showed that:Compared with the amiodarone group, the left atrial diameter was smaller (MD=-1.49, 95% CI -1.82 to -1.15), and the maintenance rates of sinus rhythm were higher (OR=3.02, 95%CI 2.21 to 4.11) in the irbesartan plus amiodarone group after 12 months.
ConclusionCurrent evidence indicates that the combination treatment of irbesartan and amiodarone for paroxysmal atrial fibrillation is better than amiodarone alone in delaying the enlargement of left atrial diameter, as well as the maintenance of sinus rhythm. Due to limited quantity and quality of the included studies, more high quality studies are needed to verify the above conclusion.
