AB  - BACKGROUND: A total of 6,500 to 8,000 steps per day are recommended for 
      cardiovascular secondary prevention. The aim of this research was to examine how 
      many steps per day patients achieve during ambulant cardiac rehabilitation (CR), 
      and if there is a correlation between the number of steps and physical and 
      cardiological parameters. METHODS: In all, 192 stable CR patients were included 
      and advised for sealed pedometry. The assessed parameters included maximum 
      working capacity and heart rate, body mass index (BMI), New York Heart 
      Association (NYHA) class, ejection fraction (EF), coronary artery disease status, 
      beta-blocker medication, age, sex, smoking behavior, and laboratory parameters. A 
      regularized regression approach called least absolute shrinkage and selection 
      operator (LASSO) was used to detect a small set of explanatory variables 
      associated with the response for steps per day. Based on these selected 
      covariates, a sparse additive regression model was fitted. RESULTS: The model 
      noted that steps per day had a strong positive correlation with maximum working 
      capacity (P=0.001), a significant negative correlation with higher age (P=0.01) 
      and smoking (smoker: P<0.05; ex-smoker: P=0.01), a positive correlation with 
      high-density lipoprotein (HDL), and a negative correlation with beta-blockers. 
      Correlation between BMI and walking activity was nonlinear (BMI 18.5-24: 
      7,427+/-2,730 steps per day; BMI 25-29: 6,448+/-2,393 steps/day; BMI 30-34: 
      6,751+/-2,393 steps per day; BMI 35-39: 5,163+/-2,574; BMI >40: 6,077+/-1,567). 
      CONCLUSION: Walking activity during CR is reduced in patients who are unfit, 
      older, smoke, or used to smoke. In addition to training recommendations, 
      estimated steps per day during CR could be seen as a baseline orientation that 
      helps patients to stay generally active or even to increase activity after CR.
