Abstract
BACKGROUND AND PURPOSE This study was to investigate the prevalence and cardiovascular risk factors (CRFs) of asymptomatic intracranial atherosclerotic stenosis (aICAS) amongst middle-aged and older adults living in rural communities in China. METHODS This population-based study included 2019 subjects (aged ≥40 years, 52.3% women) who were free of stroke and living in rural communities in China. From October 2017 to May 2018, data on demographics, CRFs and health conditions were collected through face-to-face interviews, physical examination and laboratory tests. Asymptomatic ICAS was detected through a two-phase procedure: a screening phase with transcranial Doppler ultrasound, followed by a diagnostic phase with magnetic resonance angiography examination. Multivariable logistic regression models were used to analyse CRFs associated with aICAS. RESULTS Of the 2019 participants, aICAS was detected in 153 persons. The overall prevalence of aICAS was 7.6%, and the prevalence of moderate-to-severe aICAS was 5.0%. The multi-adjusted odds ratio (95% confidence interval) of aICAS associated with CRFs was 2.40 (1.56-3.69) for hypertension, 1.91 (1.32-2.76) for high hypersensitive C-reactive protein, 1.68 (1.14-2.49) for diabetes and 1.61 (1.08-2.41) for overweight or obesity. When these four CRFs were aggregated, compared with participants without any of these factors, the multi-adjusted odds ratios (95% confidence interval) of aICAS for persons concurrently having one, two and three or more of these factors were 1.14 (0.52-2.48), 2.91 (1.42-5.99) and 5.51 (2.64-11.50), respectively (P for linear trend <0.001). CONCLUSIONS Asymptomatic ICAS is common amongst rural-dwelling middle-aged and older Chinese people. Hypertension, diabetes, overweight or obesity and high hypersensitive C-reactive protein, especially when coexisting, are strongly associated with aICAS.

Genetic Variants on SCN5A, KCNQ1, and KCNH2 in Patients with Ventricular Arrhythmias during Acute Myocardial Infarction in a Chinese Population. Cardiology 2019; 145:38-45. [PMID: 31751991 DOI: 10.1159/000502833] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Accepted: 08/20/2019] [Indexed: 11/19/2022]
Abstract
OBJECTIVE Acute myocardial infarction (AMI) remains a leading cause of morbidity and mortality worldwide. About half of sudden deaths from AMI are mainly because of malignant ventricular arrhythmias (VA) after AMI. The sodium channel gene SCN5A and potassium channel genes KCNQ1 and KCNH2 have been widely reported to be genetic risk factors for arrhythmia including Brugada syndrome and long QT syndrome (LQTS). A few studies reported the association of SCN5A variant with ventricular tachycardia (VT)/ventricular fibrillation (VF) complicating AMI. However, little is known about the role of KCNQ1 and KCNH2 in AMI with VA (AMI_VA). This study focuses on investigating the potential variants on SCN5A, KCNQ1, and KCNH2 contributing to AMI with VA in a Chinese population. MATERIALS AND METHODS In total, 139 patients with AMI_VA, and 337 patients with AMI only, were included. Thirty exonic sites were selected to be screened. Sanger sequencing was used to detect variants. A subsequent association study was also performed between AMI_VA and AMI. RESULTS Twelve variants [5 on KCNH2(NM_000238.3), 3 on KCNQ1(NM_000218.2), and 4 on SCN5A(NM_198056.2)] were identified in AMI_VA patients. Only 5 (KCNH2: c.2690A>C; KCNQ1: c.1927G>A, c.1343delC; SCN5A: c.1673A>G, c.3578G>A) of them are missense variants. Two (KCNQ1: c.1343delC and SCN5A: c.3578G>A) of the missense variants were predicted to be clinically pathogenic. All these variants were further genotyped in an AMI without VA group. The association study identified a statistically significant difference in genotype frequency of KCNH2: c.1539C>T and KCNH2: c.1467C>T between the AMI and AMI_VA groups. Moreover, 2 rare variants (KCNQ1: c.1944C>T and SCN5A: c.3621C>T) showed an elevated allelic frequency (more than 1.5-fold) in the AMI_VA group when compared to the AMI group. CONCLUSION Twelve variants (predicting from benign/VUS to pathogenic) were identified on KCNH2, KCNQ1, and SCN5A in patients with AMI_VA. Genotype frequency comparison between AMI_VA and AMI identified 2 significant common variants on KCNH2. Meanwhile, the allelic frequency of 2 rare variants on KCNQ1 and SCN5A, respectively, were identified to be enriched in AMI_VA, although there was no statistical significance. The present study suggests that the ion-channel genes KCNH2, KCNQ1, and SCN5A may contribute to the pathogenesis of VA during AMI.

Abstract
Abstract
Objective
As the impairment of myocardial micro-environments due to coronary micro-embolization (CME) compromises the treatment effect of percutaneous coronary intervention and leads to adverse prognosis, we hypothesized that endothelial progenitor cells (EPCs) transplantation could improve cardiac function in the condition of CME.
Materials and methods
Low- (2×105) and high- (2×106) dose rat bone marrow-derived EPCs were transplanted in a model of CME. To develop a CME model, rats were injected with autologous micro-blood clots into the left ventricle. Echocardiography was examined before and 1, 7, and 28 days after EPC transplantation; serum cTNI, vWF,and cardiac microRNA expression were examined one day after EPCs transplantation. Heart morphology and VEGF, vWF, and bFGF expression were examined one day after EPC transplantation.
Figure 1. Results
Results
After 10 days of culture inductions, BM-EPCs have high purity as confirmed by flow cytometry. Cardiac function reflected by LVEF significantly decreased after CME treatment and rescued by low-dose EPC. Compared to the sham group, cTNI, and vWF serum levels increased significantly after CME treatment and rescued by low-dose EPC and high-dose EPC. Low-dose EPC treatment decreased myocardial necrosis and fibrosis and elevated cardiac expression of VEGF and vWF, while decreasing the cardiac expression of bFGF. Low-dose EPC treatment significantly suppressed cardiac expression of microRNA-19a but significantly enhanced microRNA-21, microRNA-214, and microRNA-486-3p expression. In conclusion, our results indicate that low-dose EPC transplantation may play a pro-angiogenic, anti-fibroblast, anti-fibrosis, and anti-necrosis role and enhance cardiac function in a rat model of CME through a microRNA-related pathway.

Abstract
Guillain-Barré syndrome (GBS) is characterized by acute immune-mediated peripheral neuropathy, which may result in rapidly progressive paralysis and fatal respiratory failure. As the underlying pathological mechanisms of GBS are unclear, we surveyed the transcriptome of rats with experimental autoimmune neuritis (EAN), a model of GBS. Briefly, sciatic nerves on both sides were collected from 8-10-week-old Lewis rats during early (10 days post-induction), peak (19 days) and late neuritis (30 days). Total RNA was sequenced to identify differentially expressed genes. Compared to control rats without induced neuritis, 33 genes were differentially expressed in the early phase (14 up-regulated and 19 down-regulated), with an adjusted P-value < 0·05 and |log2 fold-change| >1, as were 137 genes in the peak phase (126 up-regulated and 11 down-regulated) and 60 genes in the late phase (58 up-regulated and two down-regulated). Eleven of these genes were common to all stages, suggesting their crucial roles throughout the disease course. Analysis of protein-protein interactions revealed Fos, Ccl2, Itgax and C3 as node genes at different stages. Functional analysis of differentially expressed genes identified biological processes and pathways that are activated as neuritis progresses. This is the first genomewide gene expression study of peripheral nerves in experimental autoimmune neuritis model. Dynamic gene expression and significantly altered biological functions were detected in different phases of the disease, increasing our understanding of the molecular mechanisms underlying EAN and highlighting potential targets for its diagnosis and treatment.

Abstract
INTRODUCTION Chronic kidney disease (CKD) has been associated with incident atrial fibrillation (AF) and its complications, but data from Asian cohorts are limited. AIM To explore the relationship of AF recurrence after catheter ablation (CA) with eGFR as a continuous variable, and with different renal function categories (normal: estimated glomerular filtration rate [eGFR] ≥90mL/min/1.73 m2; mild CKD: eGFR 60-89mL/min/1.73 m2; moderate CKD: eGFR 45-59mL/min/1.73 m2; severe CKD: <45mL/min/1.73 m2), using data from the Guangzhou Atrial Fibrillation Ablation Registry. METHODS We studied consecutive symptomatic adult patients with non-valvular AF, refractory to at least one antiarrhythmic drug and eligible for CA, in Guangdong General Hospital between June 2011 and August 2015. RESULTS Data were available from 1407 consecutive patients (mean age 57.3±11.5 years; 68% men) with non-valvular AF undergoing radiofrequency or cryoballoon ablation. During a mean follow-up of 20.7±8.8 months, 18.6% of patients with paroxysmal AF and 50.5% with non-paroxysmal AF had AF recurrence. On multivariable analysis, eGFR (hazard ratio [HR] 0.97, 95% confidence interval [CI] 0.96-0.97) was an independent risk factor for AF recurrence, with a good predictive value (area under the curve 0.74, 95% CI 0.72-0.77; P<0.01). In the normal renal function, and mild, moderate and severe CKD categories, AF recurrence rates were 11.5%, 29.3%, 72.0% and 93.3%, respectively. Compared with normal renal function, there were stepwise increased risks of AF recurrence with mild CKD (HR 3.30, 95% CI 2.55-4.26; P<0.01), moderate CKD (HR 9.43, 95% CI 6.76-13.16; P<0.01) and severe CKD (HR 12.35, 95% CI 6.93-21.99; P<0.01). CONCLUSIONS In a large cohort of Asian patients with AF, renal dysfunction increased the risk of AF recurrence after CA. AF recurrence gradually increased with worsening kidney function in this cohort.

Abstract
Atrial fibrillation (AF) and heart failure (HF) are two clinical entities that can present either separately or concurrently. One entity can lead to the other and vice versa as AF can not only be the underlying etiology of HF but also exacerbate HF due to other cardiac diseases. Besides prevention of cerebral and systemic embolism and elimination of AF-related symptoms, restoration of sinus rhythm for AF patients helps to avoid or reduce HF, irrespective of their underlying heart disease. Successful rates of medical therapy for AF are low in persistent AF, and much lower in long-standing AF, while invasive procedures for AF yield promising results. In this review, the authors evaluate the value of invasive therapies for HF patients complicated with non-valvular AF. We examine this clinical problem by interpreting the relationships between these two entities: the mechanism of tachycardia-induced cardiomyopathy (TIC), past opinions about rhythm control and rate control of AF, discrimination of HF-related AF and AF-induced HF, how to identify the AF patients that could benefit from invasive therapies, and how to select invasive therapies for different AF patients and peri-operative treatments.

Abstract
Background To explore an effective, reproducible and less invasive surgical approach for lone atrial fibrillation (AF). Methods A modified "mini-maze" including pulmonary vein isolation (PVI), box-lesion and left atrial appendage (LAA) resection was applied for AF patients in our center from January 2016 to June 2017. A 2.5 cm thoracotomy extended with tissue retractor was made as working port in the fourth intercostal space on each anterior side of the chest. The thoracoscope was inserted in another port lateral to main port for observing. During PVI, the tip of the clamp could be adjusted to reach as superior as the roof of left atrium for transmural lesions. The floor line was made by linear ablation pen. The LAA was removed by stapler before PVI for better exposure of the roof. Results This modified "mini-maze" was successfully completed in 53 non-paroxysmal AF patients except 1 was converted to sternotomy due to intraoperative hemorrhage. All patients recovered uneventfully. Seven-day Holter was accessed in 3, 6 and 12 months respectively in all patients. The mean follow-up was 14 (range, 3-30) months. Sinus rhythm was achieved in 48.1%, 64.8% before discharge and 3 months after surgery respectively, Twenty-eight patients in sinus rhythm or not, underwent catheter mapping and ablation three months after the operation to conform the lesion set made by this procedure. Sinus rhythm reached 87.0% after subsequent catheter ablation without any anti-arrhythmia treatment at 12 months. All patients survived without stroke, hemorrhage and pulmonary vein stenosis. Conclusions Modified "mini-maze" procedure is safe, less invasive and highly reproducible for lone AF. Sequential hybrid procedure will shape the treatment of non-paroxysmal AF.

Abstract
Objective: To explore the predictive factors for determining the therapeutic response and prognosis of severe thrombocytopenia (TP) in patients with primary Sjögren syndrome(pSS). Method: Patients with pSS and severe TP (platelet count ≤ 50×10(9)/L) admitted between 2010 to 2016 at Peking Union Medical College Hospital were classified according to their therapeutic response and analyzed retrospectively. The response parameters and clinical data including bone marrow aspiration results and laboratory findings were collected. Result: Thirty patients were finally analyzed, including twenty with appreciable bone marrow aspiration results. Fourteen and 7 patients achieved a complete response (CR) and a partial response (PR) respectively, other 9 patients with no response (NR). The megakaryocyte counts in bone marrow (BM-MK) counts per slide in each group were 13.0 (9.2,23.5) in CR patients, 7.0 (7.0,20.0) in PR patients, and 5.0 (1.0,6.0) in NR patients. BM-MK counts in patients with clinical response (CR+PR) were significantly higher than those with NR (P=0.006). A receiver-operation characteristic analysis revealed a cutoff value of BM-MK counts at 6.5 per slide stratifying patients by different responses with a sensitivity of 13/14, a specificity of 6/7, and area under the curve of 0.879. Univariate analysis indicated a better prognosis as BM-MK counts>6.5 per slide. Conclusion: BM-MK count could be a predictive factor of response in patients with pSS and severe TP. Patients with BM-MK counts≤6.5 per slide represent worse platelet improvement..

Abstract
BACKGROUND Cardiac involvement in Danon disease typically manifests as left ventricular hypertrophy (LVH) and ventricular preexcitation. This study aimed to identify patients with Danon disease among patients with LVH and concurrent electrocardiographic preexcitation. METHODS Electrocardiographic preexcitation was identified in 10 of 197 patients with unexplained LVH in whom genetic testing was performed using next-generation sequencing. RESULTS Three (3/10, 30%) patients with Danon disease were found in association with different mutations in the gene of lysosome-associated membrane protein 2 (LAMP2). Compared to seven patients without Danon disease, these three patients presented with distinctive clinical phenotypes, including onset at an earlier age (20 ± 2 years vs. 53 ± 9 years, p < 0.001), more neurological involvements (100% vs. 0, p = 0.008), higher electrocardiographic voltages (10 ± 1 mV vs. 5 ± 1 mV, p < 0.001), wider QRS complexes (163 ± 5 ms vs. 115 ± 20 ms, p = 0.006), less common asymmetric hypertrophy (0% vs. 86%, p = 0.033), and more frequent elevation of three serum enzymes (creatine kinase, aspartate aminotransferase, and lactate dehydrogenase). Intracellular vacuoles accumulation with deficiencies of LAMP2 protein was found in both cardiac and skeletal myocytes of patients with Danon disease. CONCLUSION In patients with coexistent LVH and ventricular preexcitation, Danon disease is common with distinctive clinical presentations. Comprehensive assessment of these resemble patients can provide valuable findings for early identification and clinical decision making of patients with Danon disease.

Abstract
Aims
Inadvertent puncture of the aortic root (AR) is a well-known complication of transseptal puncture (TSP). Strategies for handling of this potentially lethal complication have not been identified yet. In this study, we present typical anatomical locations and clinical management of aortic root puncture (ARP) due to TSP.
Methods and results
All patients with ARP were retrospectively collected from seven hospitals. Aortic root puncture was identified and classified regarding angiographical and intraoperative findings in cardiac surgery: (i) TSP from the right atrium (RA) to the non-coronary sinus (NCS), (ii) TSP from RA to the non-coronary sinutubular junction (STJ), and (iii) TSP from RA to the ascending aorta (AA). A total of 24 patients with inadvertent ARP were identified. In 19 patients, penetration of the aorta was accomplished by the inner dilator, in 5 patients by the complete sheath. Previous cardiac surgery had been performed in six patients. There were 13 RA-to-NCS punctures, 2 RA-to-STJ punctures, and 9 RA-to-AA punctures. No cardiac tamponade (CT) occurred in patients with RA-to-NCS and RA-to-STJ punctures. In 8 of 9 patients with RA-to-AA puncture, CT occurred immediately requiring urgent pericardiocentesis and surgical repair. Two patients died after surgical repair. In the 16 patients without surgical therapy, no shunt from the AR to the RA was observed 3 months after the procedure.
Conclusion
Aortic root puncture due to mislead TSP via NCS or STJ is usually not associated with a severe clinical course while ARP into the AA via the epicardial space generally leads to CT requiring surgical repair.

Abstract
Endoplasmic reticulum (ER) stress is mediated by disturbance of Ca2+ homeostasis. The store-operated calcium (SOC) channel is the primary Ca2+ channel in non-excitable cells, but its participation in agent-induced ER stress is not clear. In this study, the effects of tunicamycin on Ca2+ influx in human umbilical vein endothelial cells (HUVECs) were observed with the fluorescent probe Fluo-4 AM. The effect of tunicamycin on the expression of the unfolded protein response (UPR)-related proteins BiP and CHOP was assayed by western blotting with or without inhibition of Orai1. Tunicamycin induced endothelial dysfunction by activating ER stress. Orai1 expression and the influx of extracellular Ca2+ in HUVECs were both upregulated during ER stress. The SOC channel inhibitor SKF96365 reversed tunicamycin-induced endothelial cell dysfunction by inhibiting ER stress. Regulation of tunicamycin-induced ER stress by Orai1 indicates that modification of Orai1 activity may have therapeutic value for conditions with ER stress-induced endothelial dysfunction.

Abstract
BACKGROUND Female sex has been linked with worse prognosis in patients with atrial fibrillation (AF). Clinical risk stratification of women with AF may help decision-making before catheter ablation (CA). AIM To evaluate arrhythmia outcomes and the predictive value of clinical scores for arrhythmia recurrence in a large cohort of Chinese patients with AF undergoing CA. METHODS A total 1410 of patients (68.1% men) who underwent AF ablation with scheduled follow-up were analysed retrospectively. Baseline characteristics and ablation outcome were compared between men and women. The predictive values of risk scoring systems for AF recurrence were assessed in women. RESULTS Recurrence, early recurrence and complications after CA were similar in women and men over similar follow-up periods (20.7±8.0 vs 20.7±9.1 months; P>0.05). Compared with men, women with AF recurrence were older and had a larger left atrial diameter (LAD), less paroxysmal AF, lower left ventricular ejection fraction, lower estimated glomerular filtration rate (eGFR) and higher serum concentrations of B-type natriuretic peptide (BNP) and C-reactive protein (CRP) (all P<0.01). Multivariable analysis showed that age, non-paroxysmal AF, body mass index, coronary artery disease, LAD, early recurrence, eGFR, BNP and CRP were independent risk factors with sex differences (all P<0.05) in the whole cohort. In women, only non-paroxysmal AF, early recurrence, BNP, CRP (all P<0.01) and history of stroke/transient ischaemic attack (P=0.016) were independent risk factors. Of the clinical scoring systems tested, MB-LATER, APPLE, CAAP-AF and BASE-AF2 scores (C-indexes 0.73, 0.72, 0.68 and 0.72, respectively; all P<0.01) had a modest predictive value for AF recurrence after CA in women. CONCLUSIONS CA for AF has similar recurrence risks in women and men, but there are sex differences in the clinical characteristics and risk factors associated with AF recurrence.

Abstract
Precise prevalence of atrial fibrillation (AF) and the associated risk factors in southern China are rarely reported. This large population-based follow-up study, the Guangzhou Heart Study, was conducted from 2015 to 2017 to fill up this gap. Permanent residents aged 35 years and above in Guangzhou city were enrolled and demographic factors of participants were collected by a structured questionnaire. Examinations of physical, electrocardiographic and biochemical indicators were performed following a standard operation procedure designed prior to the field investigation. Descriptive statistics were used to evaluate basic characteristics of the study participants, and multivariate logistic regression model was performed to assess the AF prevalence-related factors. The detailed study design, the baseline characteristics and the prevalence of AF were reported here. In total, 12,013 residents were enrolled, and the percentage of participants from rural and urban areas was 53.92% and 46.08%, respectively. In total, 90.57% participants aged 40-79 years old and the proportion of women was more than men (64.98% vs. 35.02%). Overall, the prevalence of AF among the participants was 1.46%. Increasing age, male sex and widowed marital status were associated with higher AF prevalence (P-value < 0.05). The prevalence of AF increased with age and climbed to approximately 5% in residents aged 80 years and over. Residents with abnormal higher blood level of total cholesterol tended to have a lower AF prevalence but a higher prevalence of AF was observed in female participants with lower level of high density lipoprotein cholesterol land higher level uric acid (all P-value < 0.05). Personal illness such as hypertension, diabetes mellitus, dyslipidemia, myocardial infarction, heart failure, stroke and transient ischemic were significantly linked to the attack of AF (all P-value < 0.05). This study will be rich resource for investigating environmental exposure and individual genetic diathesis of AF and other common cardiovascular diseases in Chinese population.

Abstract
Objective: To explore histological composition of thrombus and clinical effect in mechanical thrombectomy of acute ischemic stroke. Methods: From March 2017 to August 2017 at the Institutes of Biology and Medical Sciences of Soochow University, hematoxylin and eosin (HE) staining was used to quantitatively analyze the composition of thrombus in 58 cases with acute ischemic stroke. The differences in components of thrombus with different TOAST classifications were compared, meanwhile, clinical data such as surgical process and prognosis were also analyzed. Results: (1) Baseline data: the age of arteriosclerosis was significantly lower than that of cardiogenic (P<0.05). There was statistically significant differences in onset to admission between the two types of stroke of other undetermined etiology (SUE) and Cardioembolism (CE) (P<0.05). (2) Histological composition of thrombus: there were no significant differences in fibrin and red blood cells (RBC) between the two types of SUE and CE thrombus (P>0.05). There were more RBC in LAA thrombus and more fibrin in CE thrombus (P<0.05). (3) Intraoperative data: the time of admission to recanalization of type LAA was longer than that of type CE (P<0.05). (4) Prognosis: there was no significant difference in the good prognosis between the two types of SUE and CE (P>0.05). It is the same between the types of LAA and CE (P>0.05). Conclusions: LAA thrombus contains more RBC, and cardiogenic thrombus contains more fibrin. Cryptogenic thrombus has the same composition with cardioembolism. The results may help to choose appropriate recanalization technique in different TOAST stroke and have guiding significance for the secondary prevention of SUE stroke.

Abstract
BACKGROUND Biomarkers have been related to the arrhythmia recurrence following catheter ablation (CA) of atrial fibrillation (AF). We hypothesized that concurrent measurement of several biomarkers would additively improve their predictive value. METHODS One thousand four hundred and ten consecutive AF patients (68% male; 57.2 ± 11.6 years) undergoing CA were enrolled. Baseline characteristics, serum B type brain natriuretic peptide (BNP) and high sensitivity C reactive protein (hsCRP), estimated glomerular filtration rate (eGFR), ablation parameters, arrhythmia data at discharge, 1, 3, 6, and then every 6 months post CA were collected. Follow-up ended when arrhythmia recurred or until 31st December 2016. RESULTS Three hundred and sixty-five (25.9%) patients had arrhythmia recurrence post-CA during a mean follow-up of 20.7 ± 8.8 months. BNP, hsCRP, and eGFR levels and their cut-off values of 237.45 pg/mL, 1.6 mg/dL, and 82.5 mL/min/1.73 m2 were good predictors for AF recurrence (all P < 0.01). On multivariate analysis, increasing BNP and hsCRP, decreasing eGFR, gender, and early recurrence (ER) were independent predictors of AF recurrence (all P < 0.01). Compared to BNP alone, BNP plus eGFR or both eGFR and CRP showed incrementally better predictive values (ROC comparisons, all P < 0.01). Similar findings were evident in the subgroups of patients with paroxysmal or nonparoxysmal AF. CONCLUSION Measurement of BNP, CRP, and eGFR were incrementally additive to clinical risk factors in a cumulative manner to improve prediction of arrhythmia recurrence post-CA of AF. The implications of poor arrhythmia outcome in AF patients with multiple abnormal biomarkers pre-CA procedure may help with patient selection and inform the likelihood of success or the need of more complicated CA procedure(s).
