6 and 7.8, respectively. When the diagnostic performance was controlled for confounders, there was no significant difference between the groups. CONCLUSION Our results indicate that ED chest pain patients with ongoing pain at arrival are younger, healthier, and have less ACS and 30-day MACE than patients with abated pain, but that there is no difference in the diagnostic accuracy of the ECG for ACS between the two groups. OBJECTIVE Endovascular aneurysm repair (EVAR) is the most commonly used method to repair abdominal aortic aneurysms. EVAR can be performed using a variety of anaesthetic techniques, including general anaesthetic (GA), regional anaesthetic (RA), and local anaesthetic (LA), but little is known about the effects that each of these anaesthetic modes have on patient outcome. The aim of this study was to assess the effect of anaesthetic technique on early outcomes after elective EVAR. METHODS Data from the UK's National Vascular Registry were analysed. All patients undergoing elective standard infrarenal EVAR between 1 January 2014 and 31 December 2016 were included. Patients with a symptomatic aneurysm treated semi-electively were excluded. The primary outcome was in hospital death within 30 days of surgery. Secondary outcomes included post-operative complications and length of hospital stay. Time to event outcomes were compared using Cox proportional hazards regression adjusted for confounders, including British ut patients were discharged from hospital more quickly in the RA and LA groups than the GA group (aHR RA/GA 1.10 [95% CI 1.03-1.17]; LA/GA 1.15 [95% CI 1.02-1.29]). Overall, 20.7% of patients experienced one or more complications (GA group, 22.1%; RA group, 16.8%; LA group, 17.7%) and pulmonary complications occurred with similar frequency in the three groups (overall 2.4%, adjusted odds ratio RA/GA 0.93 [95% CI 0.66-1.32]; LA/GA 0.82 [95% CI 0.41-1.63]). CONCLUSION Thirty day mortality was lower with RA than with GA, but mode of anaesthesia was not associated with increased complications for patients undergoing elective standard infrarenal EVAR.

Over the years the introduction of exposure index (EI) has been used to resolve this phenomenon referred to as 'dose creep'. Even though EI is often vendor specific it is always a related of the radiation exposure to the detector. Due to the nature of this relationship EI can also be used as a patient dose indicator, however this is not widely investigated in literature. METHODS A total of 420 dose-area-product (DAP) and EI measurements were taken whilst varying kVp, mAs and body habitus on two different anthropomorphic phantoms (pelvis and chest). Using linear regression, the correlation between EI and DAP were examined. Additionally, two separate region of interest (ROI) placements/per phantom where examined in order to research any effect on EI. RESULTS When dividing the data into subsets, a strong correlation between EI and DAP was shown with all R-squared values > 0.987. Comparison between the ROI placements showed a significant difference between EIs for both placements. CONCLUSION This research shows a clear relationship between EI and radiation dose which is dependent on a wide variety of factors such as ROI placement, body habitus. In addition, pathology and manufacturer specific EI's are likely to be of influence as well. IMPLICATIONS FOR PRACTICE The combination of DAP and EI might be used as a patient dose indicator. However, the influencing factors as mentioned in the conclusion should be considered and examined before implementation. BACKGROUND This study aimed to clarify the relationship between physical performance and prognosis of patients with heart failure using a meta-analysis given the inconsistencies in published studies regarding the same. METHODS A total of 22 studies with 10,368 patients were included in this review. Hazard ratios were used for analysis, while meta-analysis was performed using the inverse-variance method. Among all physical performance tests reported in the literature, the six-minute walk distance (6MD) test was most frequently used. However, short physical performance battery (SPPB) and walking speed were more frequently used as outcomes among studies investigating patients with a higher mean age. RESULTS The results of our meta-analysis showed that 6MD cut-off values were significantly associated with mortality [hazard ratio (HR), 2.04; 95% confidence interval (CI), 1.48-2.83; p less then 0.001] and cardiovascular disease (HR, 2.18; 95% CI, 1.68-2.83; p less then 0.001). Although a number of studies have also reported on the relationship between other physical performance tests and prognosis, meta-analysis could not be performed. Our results revealed that physical performance was strongly correlated with prognosis among patients with heart failure. CONCLUSIONS Our meta-analysis showed a strong relationship between 6MD and prognosis. However, studies investigating more elderly patients have tended to more frequently utilize walking speed and SPPB as outcomes. OBJECTIVE To assess the association between a comprehensive smoking ban and hospitalization rates for acute myocardial infarction (AMI). METHODS An observational study was conducted to assess changes in hospital admission rates for AMI in the Autonomous Community of Valencia, Spain (population 5 million), during the period 1995-2013. Law 28/2005 prohibited smoking in all enclosed spaces (public and private), and Law 42/2010 extended the ban to bars and restaurants as well as children's playgrounds and access areas of schools and hospitals. Data on hospital admissions were obtained from the Hospital Discharge Database (CMBD) of the Autonomous Community. Annual hospital admission rates per 100000 population for AMI (ICD-9-CM code 410) for men and women were calculated. RESULTS Adjusted hospital admission rates per 100000 population for AMI decreased markedly from 141.1 in 2005 to 119.2 in 2007, with a further reduction to 102.9 in 2013. Reductions in hospital admission were recorded in both men and women, but the downward trends were stronger in women.
