Key result
LV mass indexation to height 2.7 applies exclusively to BMI >30 due to poor BSA consistency.
Why the study?
The study sought to assess the sensitivity, specificity, accuracy, and consistency of the two most common left ventricular mass indexation methods across different body mass indexes.
Which method of left ventricular mass indexation (height^2.7 vs body surface area) is more consistent for diagnosing left ventricular hypertrophy across different body mass index categories?
Observational
Which method of left ventricular mass indexation (height^2.7 vs body surface area) is more consistent for diagnosing left ventricular hypertrophy across different body mass index categories?
In obese patients (BMI >30 kg/m2), left ventricular mass should be indexed to height^2.7 rather than body surface area for accurate diagnosis of left ventricular hypertrophy.
Supports height^{2.7} indexation for LV mass in obesity; leaves open prospective outcome validation before practice change.
We provided historical aspects and some features of different ultrasound diagnostic methods of left ventricular hypertrophy, their advantages and disadvantages. Using some methods of statistical analysis, we tried to assess the sensitivity, specificity, accuracy and consistency of the two most commonly used methods of left ventricular mass indexations (to the body surface area and to the height 2.7) among patients with different body mass indexes. According to our results, among patients with body mass index less than 25.0 kg/m2, both left ventricular myocardial mass indexations have good consistency with each other and can be effectively used in the diagnostic of left ventricular hypertrophy. Fairly good consistency between the studied criteria among patients with a body mass index of 25.0–29.9 also, theoretically, allows to use both methods of indexation for the diagnosing of this pathology. According to the poor consistency of the studied criteria, in case of body mass index more than 30.0 kg/m2, left ventricular myocardial mass indexation to height 2,7 should be used only.
