RESUMEN
Myocardial infarction is one of the main factors causing heart failure and is associated with a high rate of morbidity and mortality in the developing countries.Due to infracted cardiac muscles,heart function will aggravate and myocardium will remodel leading to exacerbation of the disease.Current treatment modalities may not be adequate to prevent myocardial remodeling.It is necessary to explore a new approach to restore the damaged myocardium.Stem cell-based therapy is developing rapidly and has been used in the field of cardiovascular disease.There are many problems still to be solved.
RESUMEN
AIM: To observe the heart rate、 electrocardiogram and electrophysiology effect of Qibo Capsule (Radix astragali, Radix aconii lateralis praeparata, etc) on rabbit model with sick sinus syndrome (SND), and to explore their therapy and mechanism. METHODS: 30 rabbits were used to establish sick sinus syndrome models and divided randomly into 3 groups: model group、 Qibo Capsule group、 Xinbao Pill group. To observe the changes of heart rate、 electrocardiogram、electrophysiology after 10 d. RESULTS: Comparison with the model group, the Qibo Capsule group had significant statistics differences in SCL (sinus cardiac cycle)、 SACT (sinoartrial conduction time)、 SNRT (sinus node recovery time)、 SNRTc (corrected sinus node recover time) and HR (heart rate) item (P0.05). CONCLUSION : The experiments show that Qibo Capsule is effective in the recovery of the functional harm of SND rabbits. It is worth further studys.
