Malnutrition and Growth Failure in Cyanotic and Acyanotic Congenital Heart Diseases   with and Without Pulmonary Hypertension

Objective: To determine the status of malnutrition and growth failure in cyanotic and acyanotic congenital heart diseases with and without pulmonary hypertension. Study Design: Cross sectional study. Place and Duration of Study: Department of Pediatric Cardiology, National Institute of Cardiovascular Diseases, Tando Muhammad Khan, Pakistan, from Jan 2020 to Oct 2021. Methodology: A total of 250 children, with echocardiography confirmed congenital heart disease, of both genders and aged below 5 years were included. All cases were divided into 4 groups, these being, acyanotic congenital heart disease with PH, acyanotic congenital heart disease without pulmonary hypertension, cyanotic congenital heart disease with pulmonary hypertension and cyanotic Congenital heart disease without pulmonary hypertension. Gender, age, body weight, height, area of residence and malnutrition status were determined in all cases and compared in between study groups. Results: There were 41(16.4%) patients with acyanotic PH, 115(46.0%) acyanotic without PH, 34(13.6%) cyanotic with pulmonary hypertension and 60(24.0%) cyanotic without pulmonary hypertension among a total of 250 cases. Significant differences were noted in terms of age, weight, and height among different study groups (p<0.001). Nutritional status as normal was noted in 51(20.4%) cases, mild malnutrition in 50(20.0%), moderate malnutrition in 65(26.0%) and 84(33.6%) with severe malnutrition. Children having cyanotic congenital heart disease and pulmonary hypertension were also found to have failure to thrive (p=0.009). Conclusion: Malnutrition and growth failure were found to be very prevalent among children with CHDs under the age of 5 years. Malnutrition was significantly more pronounced among children having cyanotic CHDs with PH.
