Correlation of body mass index (BMI)‎ with cardiac and ventricular repolarization parameters in young healthy students

الملخص EN

Background: Recently, increased frequency in cardiovascular events was observed in young population.

It has not been clearly determined whether cardiac and ventricular repolarization parameters differ between the young who have normal body mass index (BMI) and the young who are in overweight BMI class.

Subjects and Methods : Forty-Three overweight (BMI-28.6 ± 1.2 kg / m2, mean age- 20.6 ± 1.5 years) and 39 normal weight (BMI - 21.8±2.0 kg / m2, mean age - 20.4 ± 1.4 years) healthy male students from Baghdad University / Medical College participated voluntarily in this study.

All subjects underwent a blood pressure measurement and an electrocardiography recording.

Results : Significant statistical differences in systolic blood pressure, diastolic blood pressure, Q-T interval duration and corrected Q-T interval duration between subjects with normal weight and those with overweight was found, also a positive linear correlation between BMI and Q-T interval duration and corrected Q-T interval duration and systolic and diastolic blood pressure.

Conclusion: Results of this study indicate that the problem of overweight in young men should not be ignored.

In a younger age group, weight gain and a higher BMI may affect cardiac and ventricular repolarization parameters, even if there are no obesity related disorders, such as diabetes, hypertension, and coronary artery disease.
