{"title":"The Utility Of HAS-BLED Score In Predicting The Bleeding Risk Of Atrial Fibrillation Patients Undergoing Percutaneous Coronary Intervention Receiving Anticoagulation And Dual Anti-platelet Therapy: A Single Center Retrospective Cohort Study","authors":"Luk Yin Cheung Adrian, Chan Chi Lin Jaclyn","doi":"10.55503/2790-6744.1211","DOIUrl":"https://doi.org/10.55503/2790-6744.1211","url":null,"abstract":"Background : The Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile international normalized ratio, Elderly and Drugs/alcohol (HAS-BLED) score is a validated bleeding risk prediction tool in patients with atrial fi brillation taking oral anticoagulation. Its predictive value in patients with atrial fi brillation undergoing percutaneous coronary intervention receiving combination of anticoagulation and antiplatelet therapy is unknown. This retrospective cohort study sought to validate the accuracy of HAS-BLED score in predicting the bleeding risk in patients with atrial fi brillation who underwent percutaneous coronary intervention receiving both anti-coagulation and dual antiplatelet therapy. Method : We calculated HAS-BLED score in 186 patients with AF undergoing coronary stenting and assessed the incidence of bleeding events de fi ned by the International Society on Thrombosis and Hemostasis (ISTH) bleeding scale. Results : The mean age of the patients was 72. The proportion of male to female was 2.93: 1. Using a HAS-BLED cut off of ≥ 3, a signi fi cantly higher incidence of bleeding was detected in the high HAS-BLED compared to the low HAS-BLED cohort. Such difference of bleeding incidence remained signi fi cant in the triple therapy subgroup whereas it became statistically insigni fi cant in the dual-antiplatelet subgroup. The predictive performance was modest (AUC 0.673, 95% CI, 0.535 e 0.811, p ¼ 0.028). Conclusion : HAS-BLED score is a simple and useful tool to predict bleeding risk in a group of atrial fi brillation patients who require triple therapy after percutaneous coronary intervention.","PeriodicalId":53534,"journal":{"name":"Journal of the Hong Kong College of Cardiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48990027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Without a prompt diagnosis and treatment, it carries high mortality and morbidity. Computed tomography (CT) of thorax and abdomen is one of the commonly used non-invasive investigation modalities for diagnosis of acute aortic dissection. Apart from making a diagnosis, there are a number of parameters in the CT images that may be helpful in providing prognostic information. In this study, prognostic values of these parameters in predicting both short term and intermediate term clinical outcomes of acute aortic dissection will be evaluated. Methods : This is a retrospective observational study involving 70 patients with diagnosis of acute aortic dissection recruited between January 2004 and December 2009 in North District Hospital in Hong Kong. Results : The mean age of these patients was 61 years old and 87% of them were male. The in-hospital mortality was 18.6% (13/70). The 30-day mortality was 24.3% (17/70). The mean maximal aortic diameter of all patients was 4.60 cm ± 1 cm. The mean maximal aortic diameter of the survived group was 4.49 cm ± 0.93 cm, whereas it was 5.22 cm ± 1.22 cm in the deceased group (p ¼ 0.032). Furthermore, the presence of patent false lumen (p ¼ 0.011) in the initial scan was also more prevalent in the deceased group. By univariate logistic regression analysis, the type of aortic dissection (OR 11.0, p ¼ 0.003), the larger maximal aortic diameter (OR 2.0, p ¼ 0.041), and also patent false lumen (OR 6.6, p ¼ 0.021) in the initial imaging were adverse prognostic indicators for in-hospital mortality. However, they were not found to be independent predictors with multivariable analysis. Conclusion : In addition to establishing the diagnosis of acute aortic dissection, the type of aortic dissection, the maximal aortic diameter, and also the patency of false lumen derived from contrast CT thorax and abdomen may also provide prognostic information with regards to in-hospital and 30-day mortality. Whether this information will lead to better clinical outcomes by earlier intervention requires further studies for con fi rmation.","PeriodicalId":53534,"journal":{"name":"Journal of the Hong Kong College of Cardiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42024005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prognostic nutritional index (PNI) is an established independent predictor of adverse outcome in various chronic illnesses. The use of PNI in patients with CLTI has not been studied. To evaluate the impact of PNI on 12-month adverse cardiovascular and limb outcomes in CLTI patients after endovascular revascularization therapy (ERT). Methods : 270 consecutive patients with CLTI (mean age 73.7 ± 11.9 years; 53% male) who underwent ERT at a single tertiary referral hospital between January 2009 and October 2016 were prospectively enrolled and analyzed. Patients were grouped by tertiles of PNI (lowest ≤ 37.5; middle 37.6 e 45.5; and highest > 45.5) at baseline de fi ned as 10 £ serum albumin (g/dL) þ 0.005 £ total lymphocyte count (per mm 3 ). Composite endpoint including all-cause mortality and amputation was considered as primary endpoint. All-cause mortality and amputation were also analyzed individually as secondary endpoints at 12-months. Multivariate Cox proportional hazards regression analyses were performed. Results : Mean PNI of the 3 groups were 32.8, 42.2 and 50.4 respectively. Co-morbidities such as end-stage renal failure, heart failure and Rutherford classi fi cations 6 were signi fi cantly more prevalent in the lowest PNI tertile (all P < 0.05). Patients in the highest PNI tertile was associated with lowest incidence of 12-month composite endpoint (9.9%), all-cause mortality (7.7%) and amputation (3.3%) compared to those in the middle (27.0%, 22.5%, 9.0%) and lowest (52.2%, 47.8%, 16.7%) respectively, and reached statistical signi fi cance (p < 0.05). Multivariate analysis demonstrated high PNI was an independent protective predictor of composite endpoint (adjusted Hazards Ratio (HR) 0.26, 95% con fi dence interval (CI): 0.12 e 0.57) and all-cause mortality (adjusted HR 0.20; 95% CI: 0.09 e 0.49). Kaplan-Meier analysis revealed that higher PNI was signi fi cantly associated with better prognosis with regard to amputation, all-cause mortality and primary composite endpoint (log rank < 0.05). Conclusions : Our results demonstrated that higher nutritional status de fi ned by prognostic nutritional index (PNI) predicted lower all-cause mortality and amputation rates in chronic limb-threatening ischemia patients after endovascular revascularization therapy.","PeriodicalId":53534,"journal":{"name":"Journal of the Hong Kong College of Cardiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44113938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the time, this neighbourhood was largely inhabited by a multicultural community of artists, writers, musicians, philosophers, and critics, a number of whom had fled Nazi persecution in Europe. Many of these intellectuals lived in Hampstead well into the 1980s and 1990s, making it one of the most vibrant artistic areas in London over a period of several decades. It was in Hampstead, on the second floor of a large Victorian house, that Chiang Yee shared a flat with Shih-I and Dymia Hsiung (Xiong Shiyi and Cai Daimei). Their circle of friends and neighbours included the married couple Wang Lixi (Shelley Wang) and Lu Jingqing, both of whom were writers and poets; Tsui Chi, a historian and writer; Hsiao Ch’ien (Xiao Qian), essayist, translator, and newspaper reporter; and the future literary translator Yang Hsien-I (Yang Xianyi), who visited London at weekends while studying at the University of Oxford. Together with their friends and families, this group comprised an important social and intellectual network of Chinese writers and artists in London during the 1930s. Later, especially after the outbreak of war, they scattered across London and to other parts of the country—notably to Oxford and Cambridge—but continued to interact and were actively involved in cultural and political activities in both the UK and China. The chapters in this collection go some way towards telling a story about the Chinese in England that up until now has received scant consideration. Although certainly not the most ostentatious part of London during the pre-war period, Hampstead, where Chiang Yee and Shih-I Hsiung made their home in the 1930s, was in striking contrast to the well-documented Limehouse district, where most of London’s Chinese residents lived at the time. By uncovering this understudied aspect of British cultural history, this volume will help create a more balanced and nuanced picture of London’s Chinese population and their artistic and intellectual contributions.","PeriodicalId":53534,"journal":{"name":"Journal of the Hong Kong College of Cardiology","volume":"1 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
