Study on Heart Measurements of the People between the age 20-40 Years Present to the Teaching Hospital Colombo North – Post mortem Study
Keywords:Heart weight, Left ventricular thickness, BMI, gender
Introduction: Presence of an enlarged heart provides a basis for determination of the cause and mechanisms
of death. Gender, physical activity, and Body Mass Index (BMI) may affect the size of organs. Knowledge on
such normal variations is needed in order to recognize the abnormalities.
Objectives- This research was conducted to study the dimensions of the heart(heart weight, left ventricular
thickness and valvular circumferences) among the young adult healthy deceased autopsies and evaluate
their association with different variables.
Methods: It was a descriptive cross-sectional study and 20-40 years of age healthy, young, adult, males and
females in equal numbers who had died suddenly were studied by considering the inclusion and exclusion
criteria. Details of the past history and the measurements were entered into a proforma and the anonymous data
were used for analysis.
Results: The study revealed that the mean values of the heart weight was 280.52g (SD+/- 42.60), it was
293.94g (SD+/-39.29) for males and 267.10g (SD+/-42.64) for females. There was no significant association
of heart weight with gender (P= 0.46410). There was a significant association between BMI and the heart
weight of the females (P= 0.0387), no such association for left ventricular wall thickness. Further, there was
a significant difference of the tricuspid valve circumference among two genders and the values were 11.6cm
(SD+/-0.82) for males and 10.7cm (SD+/-0.6) for females.
Conclusions: Majority of the findings was consistent with the findings of the studies globally on Caucasians.
Increased body mass index was significantly associated with increased heart weight among females which
could probably be explained as a consequence of increased epicardial fat since there was no such association
for left ventricular wall thickness.
