Why the study?

Does supervised physical training improve functional capacity and quality of life in patients with chronic heart failure?

Population

43 patients with chronic heart failure, New York Heart Association class II or III, mean age 68 years.

Comparison

Supervised aerobic and resistance training… vs Control group (no supervised training).

Design

RCT, Randomized to either a training group (n = 21) or a control group (n = 22).

Follow-up

5 months

Overview

Supports supervised aerobic/resistance training in NYHA II-III HF; reinforces RCT evidence for functional gains in chronic heart failure.

Key Points

  • To evaluate the safety and functional effects of a supervised aerobic and resistance training program on central and peripheral parameters in patients with chronic heart failure.
  • Prospective randomized study of 43 patients with chronic heart failure (NYHA class II or III, mean age 68 years) assigned to a training group (n = 21) or a control group (n = 22).
  • The intervention group completed supervised aerobic and resistance training twice weekly for five months.
  • Assessments repeated at baseline and post-intervention included peak VO2, 6-minute walk distance, quadriceps muscle strength, echocardiography, pulmonary function, quality of life, and plasma ANP and BNP levels.
  • The training group showed significant improvements compared to controls in 6-minute walk distance (+37.1 m vs. +5.3 m, p = 0.01), bicycle exercise workload (+6.1 W vs. +2.1 W, p = 0.03), and bicycle exercise duration (+41 s vs. +0 s, p = 0.02).
  • Quadriceps muscle strength increased significantly in the exercise group compared to controls (+2.8 kg vs. +0.2 kg, p = 0.003), accompanied by significant gains in quality of life metrics reflecting exercise tolerance.
  • No exercise-related adverse events occurred, and no other significant between-group changes were observed in central cardiovascular performance.

Structured PICO

Does supervised physical training improve functional capacity and quality of life in patients with chronic heart failure?

P
Population
43 patients with chronic heart failure (CHF), New York Heart Association (NYHA) class II or III, mean age 68 years.
I
Intervention
Supervised aerobic and resistance training program twice a week for five months.
C
Comparator
Control group (no supervised training).
O
Outcome
Central and peripheral factors including VO2 peak, 6 min walk distance, muscle strength, plasma levels of ANP and BNP, echocardiogram, pulmonary function, and quality of life at 5 months.surrogate

Supervised aerobic and resistance training twice a week for five months safely improves functional capacity and quality of life in patients with NYHA class II-III chronic heart failure.
