Chan","doi":"10.55503/2790-6744.1210","DOIUrl":"https://doi.org/10.55503/2790-6744.1210","url":null,"abstract":"Background : Acute aortic dissection is a potentially life-threatening condition among patients presenting with chest pain to emergency department. 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":null,"pages":null},"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":null,"pages":null},"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}

This study aims to up-date the epidemiology of IE and to identify predictors of adverse outcome in the Chinese population in Hong Kong. Methods : This was a single-centre retrospective study of patients diagnosed with IE in Princess Margaret Hospital in Hong Kong during 2002 e 2016. Primary outcome was de fi ned as in-hospital mortality. Secondary outcomes included 1-year mortality, valvular surgical intervention, heart failure, stroke and systemic embolization. Results : In total, 196 patients with de fi nite or possible IE were included in the study. The incidence of IE was 2.26 per 100,000 person-years and had remained stable. Health care-associated IE (HCAIE) accounted for 32% of cases, with an increasing trend. Staphylococcus aureus was the most frequently isolated organism in the overall study population (37.8%) and among intravenous drug users (85.2%). In-hospital mortality remained high (29.1%) and was independently associated with higher Charlson Comorbidity Index (OR 1.24, p ¼ 0.001), heart failure (OR 5.65, p < 0.001) and the presence of large vegetation ≥ 1 cm (OR 4.67, p < 0.001).
