Effect of coenzyme complex and potassium magnesium aspartate on heart restoration rhythm and antiarrhythmia in valve replacement postoperative patients of rheumatic heart disease / 中国综合临床

ABSTRACT

Objective To evaluate the curative effect of coenzyme complex and potassium magnesium aspartate on the restoration of rhythm and anti-arrhythmia in postoperative valve replacement patients for rheumatic heart disease.Methods Eight two patients with rheumatic heart disease were randomized into 2 groups,with no statistical significance in the patients' parameters.Treatment group A (n =41 )received i.v.coenzyme complex and potassium magnesium aspartate 30 ml during operation.Group B ( n =41 ) were only given potassium magnesium aspartate 30 ml.Other conventional therapies were the same for the two groups.At the same time,rate of spontaneous restoration of rhythm and severe arrhythmia incidences and low cardiac output syndrome were also recorded.Results The rate of spontaneous restoration of rhythm in the treatment group were higher than that in the control group ( 97.56％ vs 80.49％,x2 =6.12,P =0.01 ).There were significant differences in the severe ventricular tachycardia,ventricle fibrillation and auricular flutter events between the 2 groups ( 19.51％ vs 41.46％,x2 =4.67,P =0.03 ).The rate of low cardiac output in the treatment group were lower than that in the control group( 14.63％ vs 36.58％.x2 =5.18,P =0.02).To evaluate the effect of combination therapy on the spontaneous restoration of rhythm,Logistic regression analysis showed that OR( odds ratio) value was 9.69 and 95％ CI( confidence interval) was 1.15 - 81.55 ( P =0.03 ).Other variables affecting the spontaneous restoration of rhythm included the time of aortic obstruction( OR =9.28,95％ CI 1.21 - 78.18,P =0.02) and cardiac function before operation ( OR =4.95,95％ CI 1.27 - 17.88,P =0.02),operating time (OR=3.99,95％CI 1.18- 11.62,P =0.04),age(OR=2.77,95％CI1.11 -9.74,P=0.04).Conclusion Combined administration of coenzyme complex and potassium and magnesium aspartate in the operation of valve replacement in patients with rheumatic heart disease is able to promote the spontaneous heart rhythm restoration and reduce the chance of severe ventricular tachycardia and low cardiac output events.
