    Background: There is wide variation in the use of radial over femoral access for patients with ACS. This study evaluates the factors associated with the selection of radial versus femoral angiography in Australia and New Zealand and the effect of access site on clinical events in acute coronary syndrome (ACS) patients. Methods: An analysis of the SNAPSHOT ACS audit was conducted during May 2012 across 286 hospitals in Australia and New Zealand. Data collected included baseline patient characteristics, hospital site details, treatment received, clinical events in-hospital and mortality at 18 months. Univariate and multivariable analyses were performed. Results: Of the 1621 patients undergoing coronary angiography, access was through the femoral artery in 1043 (63%), and the radial in 578 (36%) patients. Radial access dominated in New Zealand (241 out of 327, 73.7%), compared to Australia (337 out of 1293, 26.1%, p≤0.001), with interstate variation (6% to 54%, p≤0.001). Independent predictors of access site included country of admission (Odds of radial, Aus v NZ OR 0.14, 95% CI 0.08-0.24, p≤0.0001), prior CABG surgery (OR 0.16, 95% CI 0.09-0.31, p≤0.0001), high GRACE score (90 th decile) (OR 0.44, 95% CI 0.21-0.91, p=0.026) and admission to a centre with high annual PCI volume (>209 cases per year) (OR 1.86, 95% CI 1.06-3.26, p=0.03). After adjustment, there was no difference in clinical events in-hospital or mortality at 18 months Conclusion: Coronary angiography in New Zealand rather than Australia is the strongest predictor of radial access in ACS patients. There was no difference in outcomes according to access site in this population based cohort study.

    Background: Use of the Freedom SOLO (FS) stentless aortic bioprosthesis is limited by a unique and as yet unexplained severe decrease in postoperative platelet count in the absence of FS-related excess bleeding or thromboembolism. We investigated whether anticoagulant-associated pseudothrombocytopaenia could explain this complication. Methods: Thirty consecutive patients (mean age 75.4+/-7.7 years, 11 [36.7%] female) underwent elective aortic valve replacement (AVR) with either the stented bovine Mitroflow (MF, n=18) or the stentless bovine FS (n=12) aortic valve bioprostheses. Serial platelet counts were performed simultaneously with sampling tubes containing tripotassium (K 3 -)-EDTA, trisodium (Na 3 )-citrate, or novel alternative magnesium sulfate (MgSO 4 , ThromboExact(TM))-based anticoagulant, respectively. Results: Postoperative platelet counts decreased compared with preoperative values in all patients (p

    Background: Long chain Omega-3 polyunsaturated fatty acids (LCn3PUFAs) may improve cardiovascular health and depression. This study investigated the relationships between erythrocyte membrane LCn3PUFA status, depression and angina symptoms in patients with heart disease. Methods: We recruited 91 patients (65 males and 26 females, mean age 59.2+/-10.3 years) with heart disease and depressive symptoms (Center for Epidemiological Studies Depression Scale, CES-D ≥ 16) and low fish/fish oil intakes. The Omega-3 Index (EPA+DHA) of erythrocyte membranes (as a percentage of total fatty acids) was assessed by gas chromatography. Depression status was measured by both self-report and clinician-report scales; CES-D and the Hamilton depression scale (HAM-D). Angina symptoms were measured using the Seattle Angina Questionnaire and the Canadian Cardiovascular Society Classification for Angina Pectoris. Results: The mean Omega-3 Index was 4.8+/-1.0% (+/-SD). Depression scores measured by CES-D and HAM-D were 29.2+/-8.8 (moderate to severe) and 11.0+/-5.7 (mild) (arbitrary units) respectively reflecting a different perception of depressive symptoms between patients and clinicians. Angina status was inversely associated with depression scores (r>-0.26, P

    초록

    Background: Aortic valve replacement is indicated in patients with severe symptomatic aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) has evolved as a potential strategy in a growing proportion of patients in preference to surgical aortic valve replacement (SAVR). This meta-analysis aims to assess the differential outcomes of TAVR and SAVR in patients enrolled in published randomised controlled trials (RCTs). Methods: A systematic literature search of Cochrane Library, EMBASE, OVID, and PubMed MEDLINE was performed. Randomised controlled trials of patients with severe AS undergoing TAVR compared with SAVR were included. Clinical outcomes and procedural complications were assessed. Results: Five RCTs with a total of 3,828 patients (1,928 TAVR and 1,900 SAVR) were analysed. There was no statistically significant difference in combined rates of all-cause mortality and stroke at 30-days for TAVR vs SAVR (6.3% vs 7.5%; OR 0.83; 95% CI: 0.64-1.08; P=0.17) or at 12 months (17.2% vs 19.2%; OR 0.87; 95% CI: 0.73-1.03; P=0.29). No statistically significant difference was seen for death or stroke separately at any time point although a numerical trend in favour of TAVR for both was recorded. Length of in-patient stay was significantly less with TAVR vs SAVR (9.6 +/- 7.7 days vs 12.2 +/- 8.8 days; OR -2.94; 95% CI: -4.64 to -1.24; P=0.0007). Major vascular complications were more frequent in patients undergoing TAVR vs SAVR (8.2% vs. 4.0%; OR 2.15; 95% CI: 1.62-2.86; P

  5. [해외논문]   Effect of Transradial Catheterisation on Patency Rates of Radial Arteries Used as a Conduit for Coronary Bypass

    Heart, lung & circulation v.26 no.3 ,pp. 296 - 300 , 2017 , 1443-9506 ,

    초록

    Background: Transradial catheterisation is known to be associated with occlusion of the radial artery with an estimated incidence of 2-10% (1). There are very few studies looking at the patency of radial artery as a bypass graft after utilisation for catheterisation. Methods: We conducted a retrospective review of patients undergoing coronary artery bypass grafting (CABG) utilising a radial artery graft. Results: Long term patency rates were 59% in radial artery grafts utilised for catheterisation prior to CABG, compared to 78% if it were not (p= 0.035). Conclusion: Patency rates of radial artery grafts are significantly lower when the same radial artery was utilised for angiography prior to coronary artery bypass grafting (CABG).

    Heart, lung & circulation v.26 no.3 ,pp. 301 - 308 , 2017 , 1443-9506 ,

    초록

    Background: The aim of this study was to evaluate the impact of missing values on the prediction performance of the model predicting 30-day mortality following cardiac surgery as an example. Methods: Information from 83,309 eligible patients, who underwent cardiac surgery, recorded in the Australia and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) database registry between 2001 and 2014, was used. An existing 30-day mortality risk prediction model developed from ANZSCTS database was re-estimated using the complete cases (CC) analysis and using multiple imputation (MI) analysis. Agreement between the risks generated by the CC and MI analysis approaches was assessed by the Bland-Altman method. Performances of the two models were compared. Results: One or more missing predictor variables were present in 15.8% of the patients in the dataset. The Bland-Altman plot demonstrated significant disagreement between the risk scores (p
