"I really like playing games together": Understanding what influences children with congenital heart disease to participate in physical activity.

Background: Participation in physical activity is essential to the long-term health and development of all children. However, children living with cardiac conditions are typically not active enough to sustain positive health outcomes. Understanding the experiences of children living with congenital heart disease in community-based settings could help inform the physical activity counselling practices of clinicians.

Performance of Fixed Heart Rate Increment Targets of 20 vs 30 Beats per Minute for Exercise Rehabilitation Prescription in Outpatients With Heart Failure.

Background: Patients with heart failure (HF) should exercise at 40%-60% heart rate reserve (HRR) during the first 3 weeks of an outpatient cardiac rehabilitation (CR) program and at 50%-80% HRR thereafter. Arbitrary methods to prescribe exercise intensity such as resting HR (RHR) plus 20 or 30 beats per minute (bpm) (RHR + 20 or RHR + 30) are recommended for inpatients after a myocardial infarction or those recovering from heart surgery. This approach has been repurposed by outpatient CR programs to prescribe exercise intensity for patients with HF, yet its efficacy has not been evaluated.
