Background: Chronic heart failure is commonly associated with inspiratory muscle weakness. However, few studies have investigated the risk factors for inspiratory muscle weakness in individuals with chronic heart failure and systolic dysfunction (left-ventricular ejection fraction [LVEF] <40%).
Methods: Seventy subjects were recruited in a cardiac center.
Article Synopsis
- - The study focused on how different exercise intensities (low vs. moderate) impact muscle strength, functional capacity, and quality of life in patients with chronic heart failure (HF).
- - Thirty-five patients were divided into three groups: a non-exercise control group, a low-intensity training group, and a moderate-intensity training group, aiming to evaluate their respiratory and peripheral muscle strength as well as overall health improvements.
- - Results showed that both training intensities improved muscle strength and walking distance, but only moderate intensity led to additional benefits in expiratory muscle strength and heart failure class status, suggesting that both types of training are effective, with moderate intensity offering extra advantages.
Heart rate variability (HRV) analysis is a useful method to assess abnormal functioning in the autonomic nervous system and to predict cardiac events in patients with heart failure (HF). HRV measurements with heart rate monitors have been validated with an electrocardiograph in healthy subjects but not in patients with HF. We explored the reproducibility of HRV in two consecutive six-minute walk tests (6MW), 60-minute apart, using a heart rate monitor (PolarS810i) and a portable electrocardiograph (called Holter) in 50 HF patients (mean age 59 years, NYHA II, left ventricular ejection fraction ~35%).

Objectives: To assess the functional capacity of children and young adults with isolated CAVB and chronic pacing of the right ventricle (RV) and evaluate its correlation with predictors of ventricular remodeling.
Objective: To compare the effects of two physical therapy exercise in-hospital programs in pulmonary function and functional capacity of patients in the postoperative period of heart transplantation.
Methods: Twenty-two heart transplanted patients were randomized to the control group (CG, n=11) and training group (TG, n=11). The control group conducted the exercise program adopted as routine in the institution and the training group has had a protocol consisting of 10 stages, with incremental exercises: breathing exercises, resistance training, stretching and walking.
