Objective: To create and validate a scoring system for predicting clinical prognosis in patients with cardiac resynchronization therapy (CRT). Methods: A cohort of 367 consecutive patients received CRT in our hospital from 2010-01 to 2015-12 were enrolled. The endpoint follow-up events were all-cause death including heart transplantation and heart failure re-admission. The patients were randomly categorized into 2 groups: Modeling group, to develop HEAL scoring system,n=300 and Veriifcation group, to validate HEAL model,n=67. HEAL system was established by Cox proportional hazards regression model, discrimination between HEAL and EARRN scoring systems was evaluated by AUC of ROC, HEAL calibration was assessed by Hosmer-Lemeshow test and clinical endpoint evaluation by 2 scoring systems were compared by Kaplan-Meier method. Results: Modeling group analysis indicated that hs-CRP (HR=1.137, 95% CI 1.072-1.205,P<0.001), big endothelin-1 (HR=1.934, 95% CI 1.066-3.507,P=0.03), left atrial diameter (HR=1.045, 95% CI 1.007-1.084,P=0.02) and NYHA IV (HR=2.583, 95% CI 1.331-5.013,P=0.005) were the independent risk factors of adverse prognosis in CRT patients. Based on β partial regression coefifcient, HEAL scoring system was established to classify the patient's risk levels: low risk<4, moderate risk 4-10 and high risk>10. AUC for risk classification in Modeling group and Verification group were 0.719(95% CI 0.629-0.809) and 0.708 (95% CI 0.539-0.878), HEAL can well distinguish clinical prognosis in patients at different risk levels (log-rank test showed in Modeling groupP<0.001 and in Veriifcation groupP=0.002); Hosmer-Lemeshow test presented good calibration,P=0.952. All 367 patients were respectively evaluated by HEAL and EARRN scoring systems, HEAL had the better discrimination than EARRN as AUC 0.763 (95% CI 0.692-0.833) vs AUC 0.602 (95% CI 0.517-0.687). Conclusion: HEAL scoring system can effectively predict adverse prognosis in CRT patients, it had the better discrimination than EARRN system and was valuable to distinguish high risk patients in clinical practice.

Objective: To analyze the clinical features and outcomes of cardiac resynchronization therapy (CRT) in patients with dilated-phase hypertrophic cardiomyopathy (DHCM). Methods: A total of 16 DHCM patients received CRT in our hospital from 2007-03 to 2016-01 were retrospectively studied to analyze their clinical features and outcomes. Results: There were 12 male and 4 female patients at the mean age of (53.3±13.5) years. Pre-operative QRS duration of ECG was (158.7±32.2) ms, left ventricular ejection fraction (LVEF) was (33.6±6.3) %, the patient with NYHA class I, II, III and IV were 1, 5, 8 and 2 respectively. 13 patients received new CRT device, 3 received upgraded device and 8 (50%) combining atrial fibrillation (AF). The patients were followed-up for (2.56±2.13) years, 5 of them died including 3 of heart failure, 1 of sudden death and 1 of stroke. At 6 months follow-up time, 7 patients had the response to CRT which was defined by the improvement of NYHA class≥1 and the absolute elevation of LVEF≥5%; NYHA class improved from (2.69±0.79) to (2.38±0.89), P=0.02; LVEF increased from (33.6±6.3) % to (40.03±9.83) %, P=0.01. Conclusion: DHCM patients with CRT indication had the higher incidence to suffer from AF, those were more in patients with traditional pacemaker or ICD upgrading. DHCM patients with CRT had the poor general prognosis, while there was still certain proportion of patients had the response to CRT.

Background The data on the prognostic values of high sensitivity C-reactive protein (hsCRP) levels in patients with advanced symp-tomatic heart failure (HF) receiving cardiac resynchronization therapy (CRT) are scarce. The aim of present study was to investigate the association of serum hsCRP levels with left ventricle reverse remodeling after six months of CRT as well as long-term outcome. Methods A total of 232 CRT patients were included. The assessment of hsCRP values, clinical status and echocardiographic data were performed at baseline and after six months of CRT. Long-term follow-up included all-cause mortality and hospitalizations for HF. Results During the mean follow-up periods of 31.3 ± 31.5 months, elevated hsCRP (>3 mg/L) prior to CRT was associated with a significant 2.39-fold increase (P=0.006) in the risk of death or HF hospitalizations. At 6-month follow-up, patients who responded to CRT showed significant reductions or maintained low in hsCRP levels (–0.5 ± 4.1 mg/L reduction) compared with non-responders (1.7 ± 6.1 mg/L increase, P=0.018). Com-pared with patients in whom 6-month hsCRP levels were reduced or remained low, patients in whom 6-month hsCRP levels were increased or maintained high experienced a significantly higher risk of subsequent death or HF hospitalizations (Log-rank P<0.001). The echocardio-graphic improvement was also better among patients in whom 6-month hsCRP levels were reduced or remained low compared to those in whom 6-month hsCRP levels were raised or maintained high. Conclusions Our findings demonstrated that measurement of baseline and follow-up hsCRP levels may be useful as prognostic markers for timely potential risk stratification and subsequent appropriate treatment strategies in patients with advanced HF undergoing CRT.

Objective:To explore the efifcacy and safety for radiofrequency catheter ablation (RFCA) of left bundle branch guided by left bundle potential (LBP), X-ray image with EnSiteNavX System in canine model.
Methods:The RFCA of left bundle branch was conducted in 13 dogs. A mapping catheter was positioned in right atrium to record right-sided His-bundle (R-His) potential, and an ablation catheter via right femoral artery was retrograded to left ventriclefor LBP mapping and ablation. Meanwhile, EnSiteNavX System was used to identify R-His, L-His and LBP at the same time. The potential characteristics in dogs with successful ablation were observed, the PR interval, QRS shape and time limit, AH interval, HV interval, the A/V electro-gram ratio in ablationcatheter at before and after ablation were recorded. The procedural time and X-ray exposure time between LBP with X-ray image method and LBP, X-ray image with EnSiteNavX System method were compared.
Results: There were 9/13 dogs received successful left bundle branch ablation, 3 dogs failed and 1 suffered from complete A-V block. At the successful ablation target site, the LBP-V was (17.8 ± 2.6) ms with the range of (13-21) ms, and the A/V electro-gram ratio<1/10. The procedural time and X-ray expose time were signiifcantly decreased in LBP, X-ray image with EnSiteNavX System method than those in LBP with X-ray image method P=0.007 and P<0.001.
Conclusion:Under the LBP, X-ray image with EnSiteNavX System guidance method, left bundle branch could be safely and effectively ablated to establish left bundle branch block (LBBB) model in experimental canine.

Objective: To explore the effects of cardiac resynchronization therapy (CRT) in patients with dispersion of re-polarization and ventricular arrhythmia.
Methods: A total of 86 consecutive patents with CRT implantation were enrolled. According to weather absolute value of LVEF increased≥10% from baseline at 6 months after CRT implantation, the patients were divided into 2 groups: Response group and Non-response group,n=43 in each group. Dispersion of re-polarization indexes as QRS duration, QTc interval, TpTe interval and the events of ventricular arrhythmia were compared between 2 groups at different time points after CRT.
Results:①In Response group, compared with pre-operation, QRS duration and TpTe interval were shorter at 1 year and within 24h after CRT implantation, allP<0.05, while the above indexes were similar in Non-response group, allP>0.05.②During 1 year after CRT implantation, the incidences of PVCs and PVC runs in Response group were much less than those in Non-response group, for lgPVCs: (1.78 ± 0.77) vs (2.73 ± 0.61), for lgPVC runs: (0.64 ± 0.48) vs (1.98 ± 0.72),P<0.05.③Multi liner regression analysis demonstrated that TpTe interval within 24h after CRT implantation was an independent predictor for both lgPVCs: (B=0.143, OR=1.154,P=0.001) and lgPVC runs: (B=0.122, OR=1.047,P=0.001).
Conclusion: CRT ventricular reverse remodeling may reduce dispersion of re-polarization and the risk of ventricular arrhythmia, therefore improve the prognosis in relevant patients; TpTe interval within 24h after CRT had the predictive value for ventricular arrhythmia.

OBJECTIVETo explore the lipid peroxidation and the testicular morphological change induced by decabrominated diphenyl ether (BDE-209) in male BALB/c mice.

METHODSTwenty one male BALB/c mice were randomly divided into three groups: the high exposure group (500 mg/kg BDE-209), the low exposure group (200 mg/kg BDE-20) and control group (normal saline). The mice were exposed by gavage one time a day for 6 weeks, then were sacrificed. Body weight, testis weight, malonyldialdehyde (MDA), total superoxide dismutase (T-SOD) and glutathione (GSH) in testis were examined. The morphological alteration of testis was observed. TUNEL assay was used to detect the apoptosis in testicular cells.

RESULTSBody weight and testis weight in high and low exposure groups were (21.6140 +/- 2.3550) g, (20.8000 +/- 1.7630) g and (0.1859 +/- 0.0349) g, (0.1718 +/- 0.0266) g, respectively, which were significantly lower than those (27.7570 +/- 1.2880) g and (0.2302 +/- 0.0335) g in the control group (P < 0.05); the testis coefficient in high exposure group was (0.8640% +/- 0.1706%), which was significantly higher than that (0.8329 +/- 0.1386%) in the control group (P < 0.05). The GSH level and SOD activities of testis in 2 BDE-209 groups were 0.044 +/- 0.006, 0.039 +/- 0.005 nmol/mg prot, and 0.735 +/- 0.179, 0.907 +/- 0.198 U/mg prot, respectively, which were significantly lower than those (0.052 +/- 0.067) mol/mg and (1.161 +/- 0.188) U/mg in the control group (P < 0.05). The levels of MDA in 2 BDE-209 groups were (2.365 +/- 0.339) and (1.752 +/- 0.366) nmol/mg prot, which were significantly higher than that (1.173 +/- 0.232 nmol/mg prot) in control group (P < 0.05). there were significant differences of SOD and MDA levels between high exposure group and low exposure group (P < 0.05). Histological examination showed that the number of spermatogenic cells and layer were decreased significantly in 2 exposure groups as compared with control group. TUNEL assay showed that apoptosis cells appeared in 2 exposure groups.

CONCLUSIONBDE-209 changed lipid peroxidation in male BALB/c mice testis and caused toxic effects on the testis.
