- Objective To determine the effect of exercise training on survival in patients with heart failure due to left ventricular systolic dysfunction. Design Collaborative meta-analysis. Inclusion criteria Randomised parallel group controlled trials of exercise training, for at least eight weeks with individual patient data on survival for at least three months. Studies reviewed Nine datasets, totalling 801 patients: 395 received exercise training and 406 were controls. Main outcome measure Death from all causes. Results During a mean (SD) follow up of 705 (729) days there were 88 (22%) deaths in the exercise arm and 105 (26%) in the control arm. Exercise training significantly reduced mortality (hazard ratio 0.65, 95% confidence interval, 0.46 to 0.92; log rank chi(2) = 5.9; P = 0.015). The secondary end point of death or admission to hospital was also reduced (0.72, 0.56 to 0.93; log rank chi(2) = 6.4; P = 0.011). No statistically significant subgroup specific treatment effect was observed. Conclusion Meta-analysis of randomised trials to date gives no evidence that properly supervised medical training programmes for patients with heart failure might be dangerous, and indeed there is clear evidence of an overall reduction in mortality. Further research should focus on optimising exercise programmes and identifying appropriate patient groups to target.

- INTRODUCTION. Assessing left ventricular (LV) dysfunction by echocardiography in ICU patients is common. In patients with cardiovascular disease mitral annular plane sys- tolic excursion (MAPSE) is known to be more sensitive in detecting abnormalities in LV function at an early stage, easily obtainable and related to prognosis. OBJECTIVES. The aim of this study was to investigate MAPSE in critically ill patients with shock and its relation to LV systolic and diastolic function, myocardial injury and to outcome. METHODS. In a prospective, observational, cohort study we enrolled 50 patients with SIRS and shock despite fluid resuscitation. Transthoracic echocardiography (TTE) mea- suring LV systolic and diastolic function was performed within 12 h after admission and daily for a 7-day observation period. TTE and laboratory measurements (high-sensitive troponin T (hsTNT), B-natriuretic peptide [BNP]) were related to 28-day mortality. Spearman rank correlation was used. RESULTS. MAPSE on day 1 correlated significantly with LV ejection fraction (LVEF), tissue Doppler indices of LV diastolic function (e ́ , E/e ́ ) and hsTNT whereas LVEF did not correlate significantly with any marker of LV diastolic function or myocardial injury; tissue Doppler of LV systolic function (TDIs) correlated significantly with LVEF and e ́ (Table 1). Compared to survivors, non-survivors had a significantly lower MAPSE (8 [IQR 7.5–11] versus 11 [IQR 8.9–13] mm; p = 0.028). Other univariate predictors were age (p = 0.033), hsTNT (p = 0.014) and Sequential Organ Failure Assessment (SOFA) scores (p = 0.007). By multivariate analysis MAPSE (OR 0.6 (95 % CI 0.5–0.9) p = 0.015) and SOFA score (OR 1.6 (95 % CI 1.1–2.3) p = 0.018) were identified as independent predictors of mor- tality. Daily measurements showed that MAPSE, as sole echocardiographic marker, was significantly lower in most days in non-survivors (p \ 0.05 at day 1–2, 4–6). CONCLUSIONS. MAPSE seemed to reflect LV systolic and diastolic function as well as myocardial injury in critically ill patients with shock. The combination of MAPSE and SOFA added to the predictive value for 28-day mortality
