Objective:To analyze the occurrence of malignant ventricular arrhythmias(VA)in elderly heart failure patients with reduced ejection fraction(HFrEF)and its influence on the prognosis.Methods:A total of 1 171 elderly patients with heart failure were included in this study.These patients were admitted to the First People's Hospital of Shangqiu from January 2017 to June 2020.They were divided into three groups: VA group(85 cases), HFrEF group(340 cases), and heart failure with normal left ventricular ejection fracture(LVEF)group(340 cases).The division was based on the propensity score matching(PSM)method with a 1∶4∶4 ratio.The main outcome measure was major adverse cardiovascular events(MACE)in the three groups, which were followed up for 2 years.Results:After PSM, the N-terminal pro-brain natriuretic peptide(NT-proBNP), left ventricular end diastolic diameter(LVEDD), and left ventricular end systolic diameter(LVESD)of the LVEF normal group were significantly lower than those of the HFrEF group and VA group, while LVEF was significantly higher( P<0.05 for all).During a median follow-up of 22(17-25)months, a total of 219 cases(28.6%)of MACE occurred, including 30 cardiac deaths, 133 readmissions with worsening heart failure, and 56 cases of acute coronary syndrome.Kaplan-Meier survival analysis revealed that the VA group had a significantly higher overall risk of MACE compared to the normal LVEF control group and LVEF reduced control group( χ2=6.213, P=0.012).Among the three groups, the VA group exhibited the highest risk of cardiogenic death and worsening heart failure readmission, surpassing the normal LVEF group and HFrEF group( χ2=4.143, 16.861, both P<0.05).The results of the multivariate Logistic regression analysis revealed that a history of VA( OR=1.317, 95% CI: 1.109-1.564, P=0.002), NT-proBNP( OR=2.138, 95% CI: 1.235-3.701, P=0.007), and LVEDD( OR=2.413, 95% CI: 1.134-5.135, P=0.022)were found to be associated with an increased risk of VA during hospitalization.Additionally, the multivariate Cox regression analysis indicated that age >68 years( HR=1.723, 95% CI: 1.134-2.618, P=0.011), new VA occurrence( HR=2.346, 95% CI: 1.268-4.341, P=0.007), diabetes( HR=2.008, 95% CI: 1.135-3.553, P=0.017), NT-proBNP>1 957.3 ng/L( HR=2.734, 95% CI: 1.368-5.464, P=0.004), LVEF<35.0%( HR=2.265, 95% CI: 1.206-4.254, P=0.011), implantable cardioverter defibrillators( HR=0.887, 95% CI: 0.789-0.997, P=0.045), and sodium glucose co transporter 2(SGLT2)inhibitors usage( HR=0.904, 95% CI: 0.833-0.981, P=0.016)were identified as factors related to MACE. Conclusions:Patients diagnosed with VA have a significantly increased risk of MACE during the follow-up period.Several factors, including age, new VA occurrence, diabetes, NT-proBNP levels, LVEF, implantable cardioverter defibrillators, and SGLT2 inhibitor usage, have been found to be associated with the risk of MACE during the follow-up.

Objective:To evaluate the relationship between sleep arousal, ambulatory blood pressure and new-onset heart failure(NOHF)in elderly patients with obstructive sleep apnea(OSA).Methods:A total of 584 elderly patients with OSA who were diagnosed and treated in our hospital between March 2015 and March 2019 were prospectively and consecutively selected, with a mean age of(70.1±7.2)years.Polysomnography(PSG)results were obtained at baseline, and the arousal index(AI)was calculated.Based on the quartiles of AI, patients were divided into 4 groups: a low-level group(AI<18.4/h, 186 cases), a low-medium level group(18.4-29.1/h, 177 cases), a medium-high level group(29.2-41.2/h, 137 cases)and a high-level group(>41.2 /h, 84 cases). Participants were followed up for 18 months, the results of ambulatory blood pressure were recorded and compared, and the relationship between AI and the risk of NOHF was analyzed.Results:Compared with the low-level group, patients in the low-medium, medium-high, and high-level groups were older(70.1, 70.3, 73.3 vs.68.7 years, F=2.726, P=0.043)and had more smokers(43.8%, 49.6%, 54.8% vs.38.2%, χ2=8.809, P=0.032), a larger body mass index(26.3, 26.7, 27.6 vs.25.4 kg/m 2, F=2.731, P=0.042), a higher Epworth sleepiness scale score(7.83, 8.50, 9.91 vs.7.64, F=5.124, P=0.018), a higher apnea hypopnea index(23.5, 34.8, 52.7 vs.17.6, F=5.632, P=0.007), lower nocturnal oxygen saturation(80.2, 75.3, 72.1 vs.83.7 mmHg, F=4.811, P=0.024), and higher N-terminal pro-B-type natriuretic peptide(NT-proBNP)levels(317.5, 337.5, 359.2 vs.267.5 pg/L, F=4.307, P=0.033). At the median follow-up(18 months, 14-24 months), the results of ambulatory blood pressure monitoring showed that 24-hour systolic blood pressure(24 h SBP)(147.3, 148.6, 156.2 vs.143.8 mmHg, F=5.4311, P=0.013), 24-hour diastolic blood pressure(24 h DBP)(80.1, 79.5, 83.7 vs.76.5 mmHg, F=5.679, P=0.011)in the low-medium, medium-high and high-level groups were higher than those in the low-level group.The results of survival analysis showed that there were 75(12.8%)cases of NOHF, mostly with preserved ejection fraction(47 cases)or mid-range ejection fraction heart failure(20 cases). The incidences of NOHF were 6.5%, 12.4%, 16.1% and 22.4%, respectively for the low level, low-medium, medium-high and high-level groups, and the risk of NOHF in the low-medium, medium-high and high-level groups was significantly higher than in the low level group(log-rank χ2=11.624, P=0.007). Variables with P<0.2 in the univariate analysis, age and sex were included in the multivariate Cox regression analysis.The results showed that age( HR=1.724, 95% CI: 1.216-3.135), diabetes( HR=1.514, 95% CI: 1.127-3.058), NT proBNP( HR=1.517, 95% CI: 1.232-2.366), nocturnal diastolic blood pressure( HR=2.004, 95% CI: 1.332-4.638), and middle-high AI level( HR=1.611, 95% CI: 1.204-2.967)and high AI level( HR=1.863, 95% CI: 1.272-3.538)were independent factors of NOHF in elderly OSA patients. Conclusions:Sleep arousal in elderly patients with OSA increases blood pressure levels and the risk of NOHF.

Objective:To assess the differences in multidimensional clinical manifestations between patients with irritable bowel syndrome (IBS) matching the Rome Ⅲ criteria but not matching Rome Ⅳ and IBS patients matching the Rome Ⅳ criteria, among patients diagnosed with IBS according to Rome Ⅲ criteria.Methods:From November 2016 to October 2017, a total of 472 IBS patients admitted to six hospitals were selected, which included Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology (139 cases), Sir Run Run Shaw Hospital, School of Medicine of Zhejiang University (95 cases), the First Affiliated Hospital of Dalian Medical University (96 cases), the Affiliated Hospital of Guizhou Medical University (90 cases), the People′s Hospital of Guangxi Zhuang Autonomous Region (20 cases), and the Second Affiliated Hospital of Xi′an Jiaotong University (32 cases). The 472 IBS patients were divided into the group that matching the Rome Ⅳ criteria (Rome Ⅳ group), and the group that matching the Rome Ⅲ criteria but not matching the Rome Ⅳ criteria (Rome Ⅲ group). The basic characteristics (IBS course, post-infectious IBS, history of smoking or drinking, etc.), abdominal symptoms, and defecation-related symptoms of two groups were compared and analyzed by face-to-face questionnaires. Multi-dimensional clinical manifestations assessment was completed by questionnaires, which included gastrointestinal symptom rating scale (GSRS), irritable bowel syndrome-severity scoring system (IBS-SSS), irritable bowel syndrome-quality of life (IBS-QOL), and hospital anxiety and depression scale (HADS). Independent sample t-test, rank sum test, and chi-square test were used for statistical analysis. Results:There were 344 patients (72.9%) in Rome Ⅳ group and 128 patients (27.1%) in Rome Ⅲ group. The IBS course of patients in Rome Ⅳ group was longer than that in Rome Ⅲ group (3.0 years (7.0 years) vs. 2.0 years (5.7 years)), and the difference was statistically significant ( Z=-2.73, P=0.006). The GSRS scores of loose stools and abdominal pain of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group, and the GSRS scores of increased exhaust and abdominal distension of IBS patients in Rome Ⅳ group were lower than those in Rome Ⅲ group (3.0(2.0) vs. 2.0(4.0), 3.0(2.0) vs.1.0(2.0), 1.5(3.0) vs. 2.0(3.0), 1.0 (3.0) vs. 2.0(3.0)), and the differences were statistically significant ( Z=-2.48, -9.90, -2.11 and -2.06, P=0.013, <0.001, =0.035 and =0.040). The proportions of fatigue and dizziness of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group (58.4% (201/344) vs. 43.0% (55/128), 30.8% (106/344) vs. 29.7% (38/128)), and the differences were statistically significant ( χ2=8.37 and 12.36, P=0.004 and <0.001). The scores of anxiety and depression subscales of the HADS of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group (6.5 (6.8) vs. 6.0 (6.0), 5.0 (6.0) vs. 3.0 (5.0)), and the differences were statistically significant ( Z=-2.58 and -2.40, P=0.010 and 0.017). The scores of IBS-SSS scale, abdominal pain severity, abdominal pain frequency, and impact on quality of life of IBS patients in Rome Ⅳ group were all higher than those in Rome Ⅲ group (249.5 (108.0) vs. 177.0 (111.8), 50.0 (25.0) vs. 20.0 (30.0), 50.0 (70.0) vs. 10.0 (30.0), 66.0 (42.0) vs. 42.5 (34.0)), and the differences were statistically significant ( Z=-7.79, -9.64, -10.65 and -2.48, P<0.001, <0.001, <0.001 and =0.013). The score of IBS-QOL for behavioral disorder of IBS patients in Rome Ⅳ group was lower than that in Rome Ⅲ group (74.5±21.6 vs. 79.2±17.7), and the difference was statistically significant ( t=-2.22, P=0.027). Conclusion:The clinical symptoms of patients mathching the Rome Ⅳ criteria are more typical and severe, as compared with those of IBS patients matching the Rome Ⅲ criteria but not matching the Rome Ⅳ criteria.

Objective To preliminarily discuss the effect of thrombectomy with the TREVO device in patients with acute ischemic stroke.Methods Six patients with acute ischemic stroke treated with TREVO device at the Department of Neurointervention,Beijing Fengtai You′anmen Hospital from April to June 2016 were analyzed retrospectively,including 2 patients with middle cerebral artery (MCA)occlusion (time window from 2. 7 to 5. 5 h),4 with basilar artery occlusion (time window from 4. 0 to 7. 0 h). The effect of thrombectomy was evaluated by the modified thrombolysis in cerebral infarction (mTICI ) scores. The National Institutes of Health Stroke Scale (NIHSS)scores were used to evaluate the neurological status of patients before and after treatment. The prognosis was evaluated by the modified Rankin scale. Results (1 )After 1 to 2 embolectomies,the occlusive arteries of 5 patients achieved recanalization (mTICI gradeⅡb-Ⅲ;posterior circulation in 4 cases,MCA in 1 case). (2)Compared with at admission,the NIHSS score in 1 of 2 patients with MCA occlusion was reduced by 8 points at discharge,and 1 was not any improvement;compared with at admission,the NIHSS scores in 3 of 4 patients with basilar artery occlusion were decreased by 8-26 points at discharge,and 1 was not any improvement;in 2 patients with MCA occlusion,the modified Rankin scale scores were 0 to 1 at 3 months after discharge (0 in 1 case,4 in 1 case);the Rankin scale scores in 4 patients with basilar artery occlusion at 3 months after discharge were 0 in 1 case,1 in 2 cases,and 5 in 1 case.Conclusion The preliminary experience of using TREVO device embolectomy for patients with acute ischemic stroke shows that it is more safe and effective.
