Insights
Left ventricular mass index (LVMI) is vital for pediatric risk stratification. This study found a 5.0% prevalence of left ventricular hypertrophy (LVH) in Nigerian children, with significant correlations between LVMI and weight, BMI, and surface area.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Health
- Biostatistics
Background:
- Left ventricular mass (LVM) index is critical for risk stratification in children.
- Assessing LVM and left ventricular hypertrophy (LVH) prevalence is essential for pediatric cardiac care.
- Understanding normative LVM values aids in diagnosing pediatric cardiovascular conditions.
Purpose of the Study:
- To document Left Ventricular Mass (LVM) values in children from Southeast Nigeria.
- To determine the prevalence of Left Ventricular Hypertrophy (LVH) in healthy Nigerian children.
- To explore correlations between Left Ventricular Mass Index (LVMI) and factors like age, gender, and height.
Main Methods:
- A descriptive study involving 218 children across three hospitals over six years.
- Echocardiographic measurements were used to assess LVH parameters and indices.
- Data analysis was performed using IBM SPSS Statistics for Windows, version 20.
Main Results:
- The prevalence of left ventricular hypertrophy (LVH) was found to be 5.0% among the studied children.
- Strong positive correlations were observed between left ventricular mass and surface area (r=0.751, p<0.001), weight (r=0.755, p<0.001), and BMI (r=0.34, p=0.004).
- A positive correlation was noted between left ventricular mass and height (r=0.126, p=0.238).
Conclusions:
- This study established mean normative values for LVM indexed to height, BMI, surface area, and weight in Nigerian children.
- These normative values can assist cardiothoracic surgeons and pediatric cardiologists in clinical decision-making.
- The findings highlight the importance of LVM assessment for pediatric cardiovascular risk stratification.
Background:
The left ventricular mass (LVM) index is a very crucial index used for risk stratification among children. This work aimed to document the LVM values among children and delineate the prevalence of LVH among healthy children in Southeast Nigeria. It elicited the correlation between Left ventricular mass index (LVMI) and age, gender and height.
Methodology:
This is a descriptive study involving 218 children drawn from one public and 2 private hospitals over six years. Echocardiographic measurements which assessed various parameters and indices of LVH were ascertained. The data was analyzed with the IBM SPSS statistics for windows, version 20 (IBM Corp, Chicago).
Results:
The prevalence of left ventricular hypertrophy among the respondents was 5.0%. There was a strong positive correlation between left ventricular mass and surface area, (n=218, r=0.751, p<0.001). There was a very strong positive correlation between left ventricular mass and weight, which was found to be statistically significant, (n=218, r=0.755, p<0.001). There was a very strong positive correlation between left ventricular mass and BMI, which was found to be statistically significant, (n=218, r=0.34, p=0.004). There was a positive correlation between left ventricular mass and height, which was found to be statistically significant, (n=218, r=0.126, p=0.238).
Conclusion:
The mean values of LVM indexed to height, BMI, surface area, and weight and compared with gender were elicited in this study. These mean normative values could be a guide for the cardiothoracic surgeon and paediatric cardiologist in some clinical decision-making.
