A Cross Sectional Analysis of Correlation of Heart Diameter and Cardio-Thoracic Ratio with Body Habitus for Evaluating Cardiac Enlargement: An Institutional Based Study

Abstract

Background: The present study was conducted for assessing the correlation of Heart Diameter and Cardio-Thoracic Ratio with Body Habitus for Evaluating Cardiac Enlargement. Materials & Methods: A total of 100 subjects were enrolled for the present study. All the patients were within the age range of 20 to 65 years. A postero-anterior chest radiograph was obtained followed by transverse Thoracic Diameter measurement. The transverse diameter of heart was the sum of maximum projections with the right and left heart borders. Heart Diameter and Cardio-Thoracic Ratio with Body Habitus was assessed. All the results were recorded in Microsoft excel sheet and were analysed by SPSS software. Results: Mean CTR among subjects with less than 30 years of age, 30 to 50 years of age and 51 to 65 years of age was 42.1%, 44.6% and 46.2% respectively. Mean HD among subjects with less than 30 years of age, 30 to 50 years of age and 51 to 65 years of age was 11.8 cm, 12.8 cm and 14.6 cm respectively. Mean CTR among males and female subjects was 43.2% and 44.1% respectively. Mean HD among males and females was 12.3 cm and 13.2 cm respectively. Mean CTR among subjects with BMI of less than 25 Kg/m2, 25 to 29.9 Kg/m2 and 30 & above Kg/m2 was 44.6%, 45.9% and 46.1% respectively. Mean HD among subjects with BMI of less than 25 Kg/m2, 25 to 29.9 Kg/m2 and 30 & above Kg/m2 was 12.3 cm, 13.9 cm and 14.1 cm respectively. Conclusion: Age was found to be significant predictor of cardiac enlargement as measured by Heart Diameter and Cardio-Thoracic Ratio with Body Habitus. Although non-significant, gender and BMI were also found to show considerable association with cardiac enlargement.
