Goal: To investigate the clinical benefits of partial body weight support for the function of Cardiopulmonary and Cardiac autonomic nerve in the early stage of Heart failure rehabilitation. Materials and Methods: We selected 90 patients with heart failure, divided into observation group (n = 45) and control group (n = 45). Both patients had the conventional drug therapy, while the observation group had the partial body weight support additionally within the 3 months treatment period. Serological examination includes brain natriuretic peptide (BNP) and aldosterone. Echocardiography detects left ventricular morphology, cardiac ejection function (EF) and cardiac autonomic nerve function. Minnesota quality of life scale (MHL) evaluates the life quality of the patients. Results: Before any treatment, there is no significant difference of serum brain natriuretic peptide (BNP), aldosterone, cardiac autonomic nerve function and the Minnesota quality of life scale (MHL) (P > 0.05). After treatment, outcome measures declined, including serum brain natriuretic peptide (BNP) and aldosterone (P < 0.01), LVESD and ESV (P < 0.01), LVEDD and EDV (P > 0.05). Outcome measures raised, including SV, CI, EF%, ΔD%. Among them, EF% had significant difference with P value < 0.05, and ΔD% with P value < 0.01. Both LF and HF raised, but LF/HF declined. The Minnesota quality of life scale (MHL) is significantly lower than before. Conclusion: Partial body weight support obviously reduces serum brain natriuretic peptide (BNP) and aldosterone, as well as improves the function of cardiopulmonary and cardiac autonomic nerve of the patients with heart failure, which at last improves the life quality.

Objective To explore immediate efficacy and safety of pulmonary veins(PV) isolation by cryoablation for the treatment of atrial fibrillation in Fujian Provincial Hospital Arrhythmia Center. Methods We analyzed the operation records and perioperative complications of 200 patients presenting with paroxysmal(n =147)or persistent(n= 53)atrial fibrillation from May 2014 to May 2015,who underwent cryoballoon catheter abla-tion(CBCA). Results Seven-hundred and sixty-nine of 818(94. 0%)PV isolated with a single cryoballoon ap-plication,respectively,Left superior pulmonary vein(LSPV)195(97. 5%)PV,Left inferior pulmonary vein(LIPV) 192(96. 0%)PV、right superior pulmonary vein(RSPV)197(98. 5%)PV、right inferior pulmonary vein(RIPV) 167(83. 5%)PV. In 32 patients(16. 0%)with 49 pulmonary veins,a focal radiofrequency was used to create a supplemental focal lesion. The average duration of operation was(108. 8±30. 9) min,the fluoroscopy time(18. 4± 5. 6) min,and the cryoablation time(41. 9±13. 0) min.Two phrenic nerve palsy occurred during the right superior PVI,and they were recovered completely after four months and three months respectively.One left subclavian vein bled one hour after the operation. There was no cardiac perforation,pericardial tamponade,ischemic stroke or esophageal fistula in all patients.Three hundreds of 303(94. 0%)PV were isolated with a single cryoballoon appli-cation in 23 mm balloon group, and 449 of 495 ( 90. 7%) PV were isolated in 28 mm balloon group. Conclusion PVI which use CBCA is a feasible,safe and effective technique for the treatment of atrial fibrillation.
Objective This study was aimed to evaluate electrophysiological characteristics of earliest activation in ventricular arrythmias originating from right ventricular outflow tract ( RVOT) tachycardia( ventricu-lar tachycardia/premature ventricular contraction, VT/PVC ) by noncontact and contact voltage mapping. Methods Fifty-one patients suffered from RVOT-PVC/VT were enrolled in this study( VT group,23 patients, non-sustained VT;PVC group,28 patients).Ensite Array noncontact mapping(St Jude,USA)was applied to find out the earliest activation( EA) and break out( BO) of PVC/VT,then contact voltage mapping of RVOT was cre-ated during sinus rhythm. The distribution of ablation targets were analyzed accordance with voltage mapping. Results The total success rate was 94.1% in all population(48/51).The success rate in VT group(95.7%, 22/23)compared with that in PVC group(92.9%,26/28).The average target voltage of VT group under sinus rhythm was significantly lower than that in PVC group [(1.0±0.9) mV vs. (1.8±1.6) mV,P=0.045].There was no significant difference in the average target voltage of VT/PVC during clinical arrhythmias[(2.4±2.0) mV vs. (2.7±2.1) mV,P=0. 845],neither was the target duration time advanced to VT/PVC QRS [(40.8± 4. 0) ms vs.(39. 2±3. 6) ms,P=0.180].VT group had more preference originating from low-voltage areas than PVC group(82. 6%vs.50%,P=0.031).The first 10 ms dV/dt in VT group was inferior to PVC group [(0. 9±0. 7)vs. (1. 7±1. 1),P=0.010].The EA-BO time of in VT group was significantly longer than PVC group [(14.3±6.0) ms vs. (10.2±4. 3) ms,P=0.044],and more agressive ablation needed(11/23 vs.6/28,P=0. 034).Conclusions VT group had lower initiate dv/dt and longer EA-BO distance,and needsed more aggressive ablations.The majority originating sites of idiopathic RVOT arrhythmias were located in low-voltage zone.VT group showed preferences.Voltage mapping may play an important role inablation of RVOT-concerned arrhythmias.
Hyperpolarization-activated cyclic nucleotide gated channels have four subtypes,named HCN1-HCN4,respectively.The HCN channels' basic structure are similar,and are expressed in many tissues and organs.The most abundant expression of HCN channels is in the brain and heart tissue.HCN channels participate in the normal physiological function of the tissues,and are closely re-lated with the organization's pathological state.Such as HCN1 mRNA expression is increased in the state of nerve injury-induced neu-ropathic pain,and HCN4 mRNA and HCN2 mRNA expression addition were often detected in pathological conditions of hypertrophic cardiomyopathy and end-stage heart failure ventricular cells.In view of the HCN channels are closely related to many diseases,therefore,it is possible to treat disease based on them.Due to the distribution of HCN channels far-ranging and its blockers non-selective,the side effects is unavoidable from clinical application.Therefore,the development of selective HCN channel subtype inhibitor is imperative.This article mainly reviews the features of HCN channels' inhibitor.
Objective After cardiac valve replacement,patients might have the opportunity of suffering from conduction abnormities.There is now still some controversy about the diagnosis and treatment of this disease.We here retrospectively studied 15 cases of permanent pacemaker implantation after cardiac valve replacement,to explore the experience of cardiac pacing in those patients.Methods Fifteen consecutive patients with atrioventricular block after valve replacement were selected in this study,which accepted permanent pacemaker implantation(PPI) at their post-surgery period.They received VVI or DDD mode cardiac pacing according one′s cardiac rhythm or economic status,and so did the location of electrode,whose demographic data was recorded.After the implantation,one month's follow-up was carried out,their NYHA heart function was classified.What′s more,their pacing reference,their electrocardiograhy indicators,such as EF fraction and LVEDD,were analyzed.Results All operations were successful in 15 patients,10 of which received VVI mode pacing,and the other DDD mode.Compared with non-pacemaker dependent(NP) group,pacemaker dependent(P) group presented a higher incidence of conduction disease(P<0.05) and longer cardiopulmonary bypass time(CPB)(P<0.01).Before,right after,one week and one month after cardiac pacing,no significant difference was found in such indexes as NYHA heart function,LVEDD,EF and pacing threshold and sensing.In all septal-location cases,the prothetic vlave was used as an "image navigation" tool for the accurate and smooth location of the active electrode.Conclusion Permanent pacemaker implantation after valve replacement was safe and effective.Already existing conduction disease(grade II and up),longer CPB time might be risk factors of later pacemaker dependency in valve replacement patients.Take advantage of the good visibility of prosthetic valve may be a novel way for the electrode′s septal location.
