title: [Predictors of exercise capacity improvement in patients after an acute coronary event during inpatient rehabilitation].
abstract: Objective Patients who suffered from an acute coronary syndrome (ACS) boast a low exercise capacity (EC). To enhance EC is a core component of cardiac rehabilitation (CR). The aim of the study was to investigate predictors of exercise capacity to optimize the rehabilitation process in untrained subgroups.
  
  
  METHODS
  47 286 patients (mean age 64±11.62, 74.5% male) were enclosed in the TROL registry. All patients underwent a bicycle stress test at admission and discharge. The dependent variable for the univariate analysis and multivariate logistic regression was the increase of EC during CR, with a cutoff of 15 Watts (pre/post design). Furthermore comorbidities and physical activity before the index event were analyzed.
  
  
  RESULTS
  Exercise capacity enhancement differs between active and inactive patients significantly (21.84 Watt vs. 16.35 Watt; p<0.001). While a male gender (OR 1.62 [95% CI: 1.51-1.74]) and physical activity before rehabilitation (OR 1.85 [95% CI: 1.75-1.97]) were positive, comorbidities and age (OR 0.82 [95% CI: 0.74-0.90]) were negative predictors.
  
  
  CONCLUSIONS
  In cardiac rehabilitation settings special exercise training programs for elderly and comorbid patients are needed, to enhance their exercise capacity sufficiently.
