| 3 | Simple hematological predictors of AF recurrence in patients undergoing atrial fibrillation ablation显示文摘Backgound Red cell distribution width(RDW) and neutrophil-to-lymphocyte ratio(NLR) are simple hematologic indices that have been used to predict adverse outcomes in different clinical settings. The aim of our study is to determine whether RDW and NLR can predict atrial fibrillation(AF) recurrence in patients undergoing AF ablation. Methods Consecutive patients, without known hematological disorders, who underwent AF catheter ablation between January 2014 and April 2017 were enrolled into this study. Blood samples were taken one day before and five hours after the ablation procedure. Results A total of 346 patients(224 males(65%), mean age: 59 ± 11 years old) were included. After a mean follow up of 26.2 ± 12.1 months, 80(23.1%) patients experienced late AF recurrence(defined as any recurrence after the blanking period of three months), while 97(28%) patients experienced early AF recurrence during the blanking period. Univariate analysis showed that early arrhythmia recurrence, type of AF and NLR after the procedure were significantly associated with late AF recurrence, while early arrhythmia recurrence and NLR remained significant in multivariate analysis. RDW was not associated with late AF recurrence. None of the parameters above predicted early arrhythmia recurrence. Conclusions Simple and inexpensive hematological indices such as NLR should be evaluated for their ability to predict AF recurrence in patients undergoing catheter ablation in larger prospective studies. | George Bazoukis Konstantinos P Letsas Konstantinos Vlachos Athanasios Saplaouras Dimitrios Asvestas Konstantinos Tyrovolas Aikaterini Rokiza Eirini Pagkalidou Gary Tse Stavros Stavrakis Antonios Sideris Michael Efremidis | 2019 | Journal of Geriatric Cardiology2019，16，9： | 4 |
| 4 | Evaluation of a point of care ultrasound curriculum for Indonesian physicians taught by fi rst-year medical students显示文摘BACKGROUND: The purpose of this study was to assess the short-term efficacy of a 4-week ultrasound curriculum taught by American first-year medical students to general practitioners working in public health care clinics, or puskesmas, in Bandung, Indonesia.METHODS: We performed a prospective, observational study of Indonesian health care practitioners from public clinics in Bandung, Indonesia. These practitioners were enrolled in a 4-week ultrasound training course taught by first-year American medical students. A total of six sessions were held comprising of 38 ultrasound milestones. A pre-course and post-course written exam and practical exam was taken by each participant.RESULTS: We enrolled 41 clinicians in the course. The average pre-course exam score was 35.2% with a 2.4% pass rate, whereas the average post-course exam score was 82.0% with a 92.7% pass rate. The average practical score at the completion of the course was 83.2%(SD=0.145) with 82.9% of the class passing(score above 75.0%).CONCLUSION: Our data suggests that first-year medical students can effectively teach ultrasound to physicians in Indonesia using a 4-week intensive ultrasound training course. Future studies are needed to determine the amount of training required for proficiency and to evaluate the physicians' perceptions of the student-instructors' depth of knowledge and skill in point of care ultrasound. | Jonathan B.Lee Christina Tse Thomas Keown Michael Louthan Christopher Gabriel Alexander Anshus Bima Hasjim Katrina Lee Esther Kim Luke Yu Allen Yu Shadi Lahham Steven Bunch Maili Alvarado Abdulatif Gari John C.Fox | 2017 | World Journal of Emergency Medicine2017，8，4： | 4 |
| 5 | Clinical, sonographic characteristics and long-term prognosis of valvular heart disease in elderly patients显示文摘Background Valvular heart disease(VHD)is expected to become more prevail as the population ages and disproportionately affects older adults.However,direct comparison of clinical characteristics,sonographic diagnosis,and outcomes in VHD patients aged over 65 years is scarce.The objective of this study was to evaluate the differences in clinical characteristics and prognosis in two age-groups of geriatric patients with VHD.Methods We retrospectively enrolled consecutive individuals aged>65 years from Guangdong Provincial Peopled Hospital and screened for VHD using transthoracic echocardiography(TTE)or transesophageal echocardiography(TEE).Finally,260(48.9%)patients were in the 65-74 years group,and 272(51.1%)were in the>75-year group.Factors that affected long-term survival was explored.A multivariable Cox hazards regression was performed to identify the predictors of major adverse cardiac events(MACEs)in each group.Results In our population,the older group were more likely to have chronic obstructive pulmonary disease(COPD),degenerative VHD,but with less rheumatic VHD,aortic stenosis(AS)and mitral stenosis(MS).Compared with those aged 65-74 years,the older group had a higher incidence of all-cause death(10.0%vs.16.5%,P=0.027),ischemic stroke(13.5%vs.20.2%,P=0.038)and MACEs(37.3%vs.48.2%,P=0.011)at long-term follow-up.In multivariable Cox regression analysis,mitral regurgitation,a history of COPD,chronic kidney disease,diabetes,hypertension,atrial fibrillation and New York Heart Association(NYHA)functional class were identified as independent predictors of MACEs in the older group.Conclusion Advanced age profoundly affect prognosis and different predictors were associated with MACEs in geriatric patients with VHD. | Feier SONG Fang-Zhou LIU Yuan-Feng LIANG Gary Tse Xin LI Hong-Tao LIAO Ji-Yan CHEN | 2019 | Journal of Geriatric Cardiology2019，16，1： | 4 |

| 8 | Impact of SGLT2 inhibitors on major clinical events and safety outcomes in heart failure patients:a meta-analysis of randomized clinical trials显示文摘BACKGROUND Sodium-glucose co-transporter-2 inhibitors(SGLT2i)significantly reduce the risk of cardiovascular(CV)and renal adverse events in patients with diabetes mellitus,heart failure(HF)and/or chronic kidney disease.We performed a meta-analysis to explore the impact of several different SGLT2i on all-cause mortality,CV mortality,HF hospitalizations and the combined outcome CV death/HF hospitalization in HF patients across the spectrum of left ventricular ejection fraction(LVEF)phenotypes.METHODS A systematic search in MEDLINE database and Cochrane library through March 2021 was performed without limitations.Randomized clinical trials that provided data about the impact of SGLT2i on all-cause mortality,CV mortality,HF hospitalizations or the combined outcome of CV death/HF hospitalization in HF patients were included.A random effects model was used for calculating the effect estimates.RESULTS Nine studies(n=16,723 patients,mean age:65.9 years,males:70.7%)were included in the quantitative synthesis.Compared to placebo,SGLT2i use was associated with 14%lower risk of all-cause mortality[hazard ratio(HR)=0.86,95%CI:0.78−0.94,I^(2)=0,P=0.0008],32%lower risk of HF hospitalizations(HR=0.68,95%CI:0.62−0.74,I^(2)=0,P<0.001),14%lower risk of CV mortality(HR=0.86,95%CI:0.77−0.95,I^(2)=0,P=0.003)and 26%lower risk of CV death/HF hospitalization(HR=0.74,95%CI:0.68−0.80,I^(2)=0,P<0.001).Regarding the safety outcomes,our data revealed no significant differences between SGLT2i and placebo groups in drug related discontinuations,amputations,severe hypoglycemia,hypotension,volume depletion,ketoacidosis and genital infections.By contrast,a protective role of SGLT2i against placebo was found for serious adverse events and acute kidney injury.CONCLUSIONS In patients with HF,regardless of LVEF phenotype,all SGLT2i had an excellent safety profile and significantly reduced the risk of all-cause mortality,CV mortality,HF hospitalizations and CV deaths/HF hospitalizations compared to placebo. | George Bazoukis Stamatis S.Papadatos Costas Thomopoulos Gary Tse Stefanos Cheilidis Konstantinos Tsioufis Dimitrios Farmakis | 2021 | Journal of Geriatric Cardiology2021，18，10： | 3 |
| 9 | A rare case of Staphylococcus lugdunensis septicemia associated with myocarditis and atrioventricular block显示文摘Myocarditis is a relatively rare,possibly life-threatening disease characterized by the inflammation of the myocardium.111 The disease pathogenesis is primarily initiated by acute injury and necrosis of cardiomyocytes,leading to an inflammatory response mediated by the immune system that can potentially cause further aggravation of myocardial damage and organ dysfunction.Prognosis in patients with myocarditis depends on the clinical presentation,which ranges from an asymptomatic disease course to the concomitant development of cardiac arrhythmias,heart failure,cardiogenic shock and even the occurrence of death in extreme cases[1]. | Alex Tsz Lai Nganh Sharen Lee Tong LIU Mark Tam Ka Hou Christien Li Michelle Vangi Wong Michael Huen Sum Lam Gary Tse Ishan Lakhani | 2019 | Journal of Geriatric Cardiology2019，16，1： | 2 |
| 10 | Superior safety of direct oral anticoagulants compared to Warfarin in patients with atrial fibrillation and underlying cancer: a national veterans affairs database study显示文摘Background Studies evaluating safety of warfarin and direct oral anticoagulants(DOACs) for prevention of stroke in patients with atrial fibrillation(AF) are lacking. Methods & Results All patients(n = 196,521) receiving care at veteran’s affairs with active cancer and AF from 2010–2015 were included. One-year mortality was significantly higher in unadjusted analysis with warfarin(44.9%) compared to dabigatran(25%, P < 0.001), rivaroxaban(24.4%, P < 0.001) and apixaban(30%, P < 0.001) and after adjusting for age, sex and type of cancer mortality(OR = 2.66, 95% CI: 2.52–2.82, P < 0.001). Risk of ischemic stroke(13.5% vs. 11.1%, 12.0%, 14.0%) was similar, however risk of hemorrhagic stroke was significantly higher among patients receiving warfarin(1.2%) compared to patients receiving dabigatran(0.5%), rivaroxaban(0.7%) and apixaban(0.8%) respectively, P = 0.04. Conclusions We demonstrated the superior safety profile of DOACs compared to warfarin among patients with underlying cancer and AF. Warfarin was associated with higher mortality, similar ischemic stroke risk but higher risk of hemorrhagic stroke. | Abhishek C Sawant Arnav Kumar Wilmon Mccray Sheldon Tetewsky Linda Parone Srilekha Sridhara Meghana Prakash Hiriyur Prakash Gary Tse Tong LIU Nidhi Kanwar Aishwarya Bhardwaj Sahoor Khan Christopher Manion Ankush Lahoti Ashish Pershad Peter Elkin John Corbelli | 2019 | Journal of Geriatric Cardiology2019，16，9： | 2 |
| 11 | Comparison of ultrasound-measured properties of the common carotid artery to tobacco smoke exposure in a cohort of Indonesian patients显示文摘BACKGROUND: The purpose of this study was to use point-of-care ultrasound(POCUS) to investigate the relationship between tobacco smoke exposure and the characteristics of the common carotid artery(CCA). The effect of both primary and secondary smoking on CCA properties was evaluated.METHODS: We performed a prospective cross-sectional study across 20 primary care clinics in Bandung, West Java, Indonesia in July 2016. Point of care ultrasound was performed on a convenience sample of Indonesian patients presenting to clinic. The CCA wall stiffness and carotid intima-media thickness(CIMT) were measured during diastole and systole. These measurements were correlated with smoke exposure and cardiovascular disease.RESULTS: We enrolled 663 patients in the study, with 426 patients enrolled in the smoking category and 237 patients enrolled in the second-hand smoke category. There was an overall positive correlation with the measured lifestyle factors and the ultrasound-measured variables in the group of individuals who smoked. For all variables, age seemed to contribute the most out of all of the lifestyle factors for the positive changes in CIMT and CCA wall stiffness.CONCLUSION: Our data yielded correlations between CCA properties and cardiovascular risk, as well as between CIMT and arterial stiffness. We were also able to demonstrate an increase in thickness of the CIMT in patients who have been exposed by tobacco through the use of ultrasound. Further large scale studies comparing patients with multiple cardiac risk factors need to be performed to confi rm the utility of ultrasound fi ndings of cardiovascular disease and stroke. | Allen R.Yu Bima Hasjim Luke E.Yu Christopher Gabriel Alexander Anshus Jonathan B.Lee Michael J.
