On the methodology of exercise training in patients with CHF
Urgency. The issue of creating a unified program for physical rehabilitation of patients with CHF, which would be physiologically relevant and available for patients at home, easy for performance and control, remains urgent. Aim. Comparing the efficacy of exercise training in patients with systolic CHF vs. patients with CHF and preserved LV EF. Materials and methods: Study included 30 patients per group with systolic CHF and CHF with preserved LV EF. For 12 months, patients of both groups performed daily exercise training by walking in a regimen of free choice. Dynamics of exercise intensity, clinical status of patients as evaluated by time course of CHF FC, LV EF, SECS (Scale for evaluation of clinical state parameters), 6-min test, quality of life and need for hospitalization were assessed. Results. Both groups significantly increased the exercise intensity, which resulted in a significant increase in parameters of 6-min test, by 23.9 m in patients with systolic CHF and by 39.5 m in patients with CHF and preserved LV EF. The CHF FC decreased in 53% of patients with CHF and preserved LV EF and in 30% of patients with systolic CHF. The LV EF significantly increased by 5% in patients with systolic CHF. Clinical status of patients significantly improved in both groups: total clinical scores by SECS were decreased by 2.1 in the group with systolic CHF and by 1.2 in the group with preserved LV EF. All patients achieved a significant improvement in their quality of life. Need for hospitalizations reduced by 25–26%.
