Home-based training program in patients with chronic heart failure and reduced ejection fraction: a randomized pilot study.

Objectives: We aimed to compare the effects of home-and center-based exercise training programs on functional capacity, inspiratory muscle strength, daily physical activity level, and quality of life (QoL) in patients with chronic heart failure (CHF) over a 12-week period.

Methods: This study included 23 patients with CHF (left ventricular ejection fraction 31±6%) randomized to a home-based (n=11) or center-based (n=12) program. Patients underwent 12 weeks of aerobic training (60%-70% heart rate reserve): walking for the home-based and supervised cycling for the center-based group, both combined with resistance training (50% of 1 maximum repetition).

Evaluation of prescription of exercise, for rehabilitation of coronary artery disease patients by myocardial scintigraphy.

Background: It is advisable that the intensity of the exercises for rehabilitation of patients with coronary artery disease does not cause myocardial ischemia.

Objective: Compare the capacity of myocardial tomographic scintigraphy with the electrocardiogram capacity in ischemia detection during rehabilitation session.

Methods: Twenty six patients with coronary artery disease, undergoing the rehabilitation program and with previous scintigraphy, with transient hypo-uptake have been administered a new injection of MIBI-Tc-99m during a training session when they were also monitored with dynamic electrocardiography.
