Background: The prognostic importance of regional systolic function, as assessed by wall motion score index(WMSI), compared with global function, as assessed by left ventricular ejection fraction(LVEF), has not been assessed in large populations after acute myocardial infarction. Methods: Echocardiograms, including the assessment of WMSI and LVEF, were performed in 767 patients with acute myocardial infarction at a median of 1 day(25th and 75th percentiles 0- 2 days) after admission. Patients were followed for a median of 19 months(range 12- 28 months). Cox proportional hazards models were constructed for the primary study end point(all- cause mortality) and for a secondary end point(hospitalization for congestive heart failure). Results: During follow- up(median 40 months; range 32- 50 months), 216 patients died and 54 patients were hospitalized for congestive heart failure. By univariate analysis, both LVEF(Pgnostic information(P=.77). Wall motion score index also proved to be an independent predictor of hospitalization for congestive heart failure(hazard ratio 1.21 per 0.2- unit increase, 95% CI 1.07- 1.37, P=.002), whereas LVEF did not(P=.56). Conclusion: Both LVEF and WMSI provide powerful prognostic information after acute myocardial infarction; however, the predictive power of WMSI is greater.

Objectives: Critical limb ischaemia (CLI) requiring infra-inguinal bypass is a common presentation to the vascular surgery service. A significant number of CLI patients also present with anaemia as a comorbidity, the impact of which is unknown. We reviewed the impact of anaemia on mortality and amputation in patients who underwent infra-inguinal bypass surgery. Methods: Demographic data from all patients who underwent infra-inguinal bypass surgery for CLI at the Flinders Medical Centre & Repatriation general Hospital, South Australia between January 2005 and January 2010 were recorded. Haemoglobin (Hb) level, serum creatinine (SCr) level, mortality and amputation events were also recorded for retrospective analysis. Results: 190 patients (141M, 49F) who underwent infra-inguinal bypass surgery over a 5 year period were analyzed. 100 (53%) of these patients had mild anaemia (mean Hb 113 g/L, mean for females 103 g/L, mean for males 116 g/L). Those who presented with anaemia were more likely to have diabetes and renal dysfunction as comorbidities. Anaemia had a significant negative impact on mortality with 30% deaths in those who were anaemic compared to 15.6% deaths in those without anaemia odds ratio (OR) 1.76, 95% CI: 0.90 - 3.48, p king at amputation as an outcome;with the number of amputations in those who were anaemic preoperatively 14% vs 6.7% in those who were not anaemic, OR 2.56, 95% CI: 1.00 - 6.54, p = 0.05. The negative impact of anaemia on mortality 43.5% vs 18.8% was also noted in patients who did not have diabetes or impaired renal function as a comorbidity p g with CLI and it predicts poor outcomes after infra-inguinal bypass. The role of transfusion is debatable, but it is clear that this group of patients requires careful management during the perioperative period to ensure they are medically optimized.

Despite mounting evidence that depressive symptoms increase the risk of morbidity and mortality in patients who have coronary artery disease, little is known about the biologicmechanisms that underlie this association. This study examined whether depressive symptoms are associated with markers of infection and inflammation that have been implicated in the pathogenesis of coronary artery disease. Sixty-five patients who were recovering from an acute coronary syndrome were enrolled(63%men; mean age 61 years, 90%white). Depressive symptoms were assessed through self-report and observer ratings; the inflammatory molecules C-reactive protein, interleukin-6, and tumor necrosis factor-αwere measured in serum, as were antibody titers to 3 latent viruses associated with atherosclerosis. Patients who had more severe depressive symptoms exhibited higher levels of C-reactive protein(r=0.27, p=0.03) and higher rates of seropositivity to the latent viruses(r=0.41, p=0.001). These effects were large in magnitude: patients in the highest tertile of the depression distribution had C-reactive protein levels >50%higher than did patients in the middle and lowest tertiles; they also were 2 times as likely to show evidence of infection with all 3 latent viruses. Disparities in the extent, severity, or management of cardiac disease were not responsible for these associations. These findings provide evidence that depressive symptoms are associated with increases in C-reactive protein and pathogen burden in patients who have coronary artery disease. In doing so, they highlight a mechanism through which depressive symptoms might foster morbidity and mortality among patients who have cardiac disease.

Objectives: Clinicians often base the implementation of therapies on the presence of postural instability in subjects with Parkinson’s disease (PD). These decisions are frequently based on the pull test from the Unified Parkinson’s Disease Rating Scale (UPDRS). We sought to determine whether combining the pull test, the one- leg stance test, the functional reach test, and UPDRS items 27- 29 (arise from chair, posture, and gait) predicts balance confidence and falling better than any test alone. Methods: The study included 67 subjects with PD. Subjects performed the one- leg stance test, the functional reach test, and the UPDRS motor exam. Subjects also responded to the Activities- specific Balance Confidence (ABC) scale and reported how many times they fell during the previous year. Regression models determined the combination of tests that optimally predicted mean ABC scores or categorised fall frequency. Results: When all tests were included in a stepwise linear regression, only gait (UPDRS item 29), the pull test (UPDRS item 30), and the oneleg stance test, in combination, represented significant predictor variables for mean ABC scores (r2 = 0.51). A multinomial logistic regression model including the one- leg stance test and gait represented the model with the fewest significant predictor variables that correctly identified the most subjects as fallers or non- fallers (85% of subjects were correctly identified). Conclusions: Multiple balance tests (including the one- leg stance test, and the gait and pull test items of the UPDRS) that assess different types of postural stress provide an optimal assessment of postural stability in subjects with PD.

Background: The mechanisms responsible for impaired cardiovascular hemodynamics during exercise among persons with milder forms of hypertension are not well documented. We examined the relationship of oxygen pulse during exercise, a correlate of stroke volume, with echocardiographic indices of resting left ventricular function to determine whether abnormal contractility and relaxation are related to abnormal cardiovascular dynamics during exercise among such persons. Methods: Subjects were 44 men and 55 women ages 55 to 75 years with mild hypertension but who were otherwise healthy. Resting left ventricular systolic and diastolic functions were assessed with 2-dimensional Doppler echocardiography and tissue Doppler imaging. Oxygen pulse(millimeters per beat)at rest and during multistage treadmill testing was derived from measurements of oxygen consumption and heart rate. The slope of oxygen pulse between successive exercise stages was calculated. Results: After a steep rise in oxygen pulse from rest to stage 1 of exercise, a markedly diminished oxygen pulse slope was seen between subsequent exercise stages. In stepwise regression analysis, the increase in the slope of oxygen pulse from rest to stage 1 was explained by a greater lean body mass(57% , Pger left atrial size(2% , Pge 1, the increase in the slope of oxygen pulse was explained by sex(24% , Pgher mitral E/A ratio(6% , Pgher mitral annular systolic velocity(6% , Pggest that a blunted oxygen pulse response to exercise among older persons with milder forms of hypertension may reflect impaired left ventricular stroke volume changes during exercise secondary to subtle abnormalities in both systolic and diastolic left ventricular functions.
