sto the target SVG. Extent score, diabetes and patient's age at the time of the procedure were independently associated with risk of death on follow-up.Conclusions: Periprocedural troponin rise, diabetes and high SVG extent score are predictive of poorer long-term outcome following PCI. The effect of high extent score and diabetes persists past 6 years.

Background: EuroSCORE was widely used for predicting outcomes after cardiac surgery, but has become poorly calibrated for contemporary cohorts. EuroSCORE II and AusSCORE, based on an Australasian population, were recently developed. We compared the performance of these three scores for coronary artery bypass grafting (CABG). Methods: All isolated CABG patients at Auckland City Hospital during July 2010-June 2012 were included. EuroSCORE I, EuroSCORE II and AusSCORE retrospectively calculated and compared for discrimination and calibration of outcomes. Results: There were 818 patients followed for 1.4 ± 0.6 years. Mean EuroSCORE I, EuroSCORE II and AusS-CORE were 4.5 ± 5.0%, 2.6 ± 3.1% and 0.9 ± 1.3%. Mortality at 30 days, follow-up and composite surgical morbidity were 1.6% (13), 2.9% (24) and 17.8% (146). C-statistic of these scores for 30-day mortality were 0.675 (95% confidence interval 0.

Although the electrocardiogram (ECG) and chest X-ray (CXR) are the standard tests in clinical practice, the diagnostic performance of these tests as compared to the promising gold standard for the diagnosis of left atrial enlargement (LAE), cardiac magnetic resonance (CMR) is not well evaluated. This study was sought to assess the accuracy of the ECG and CXR criteria to diagnose LAE determined by volumetric CMR. Methods: A total of 100 patients referred for CMR (46.2% males, 70.7 + 10 years) were consecutively enrolled. The standard ECG and CXR criteria for LAE were independently analysed. Left atrial volume index (LAVI) was calculated using the biplane area-length method from CMR blinded to the ECG and CXR results. Results: Mean LAVI was 48.7 + 17.9 ml/m 2 and mean left ventricular ejection fraction was 61.1 + 7.6%. The prevalence of LAE was 78% by CMR (with the cutoff point of 28 mL/m 2), 36% by ECG, 45% by CXR and 53% by either ECG or CXR. LAE by ECG and CXR was correlated with mean LA volume index by CMR of 62.6 + 18.7 mL/m 2 and 54.6 + 12.5 mL/m 2 respectively. Conclusion: The LAE from ECG and CXR criteria were correlated with marked LA enlargement. These findings from our study emphasised the lack of sensitivity of LAE by ECG and CXR criteria. Conventional ECG and CXR use in clinical practice may lead to underestimation of risk stratification.
