ABSTRACT

Congenital Heart Disease is a condition present since birth having malformed heart structure and function. The malfunction of the heart hemodynamics requires palliative, supportive and corrective surgery. Children with congenital heart disease have compromised physiological function compared to normal with the same age and anthropometric measures. The energy consumption for a given submaximal work would be more in CHD patients compared to normal. The physiologic cost index calculated the energy expenditure and gives an idea about the same during walking. PCI can be used as an outcome measure to plan and tailor a rehabilitation exercise program. So the present observational study calculates the energy expenditure in repaired congenital heart disease patient and provides the baseline for a goal to achieve during any rehabilitation program by comparing with the normal. To compare the physiological cost index (PCI) between repaired congenital heart disease patients and healthy children. The study design is observational. Total 40 participants will be selected as per the criteria for inclusion and exclusion i.e. 20 healthy children and 20 with repaired congenital heart disease. The duration of the study will be for six months.The six-minute walk will be performed according to guidelines, and PCI will be calculated using MacGregor’s formula. From the data will be calculated using PCI formula while performing 6MWT. PCI can be used as an effective tool for a physiotherapist in the assessment and evaluation of functional performance and provide the baseline for repaired CHD children. Many studies have evaluated functional performance in patients with coronary artery disease and there is the a paucity of studies in repaired congenital heart disease, so the present study aims at evaluation and comparison of PCI in repaired CHD and healthy children.
