Why is body composition analysis an
effective tool for treating cardiovascular diseases?
Disclaimer: InBody devices should be used as an adjunct tool for clinical decision making and are not intended to diagnose or treat any diseases.
Body composition is important for understanding a patient’s cardiovascular health. High blood volume, increased water levels in the body, strains on the heart are all issues that stem from conditions like obesity. BMI is commonly used to determine a patient’s risk for cardiovascular disease; however, BMI overlooks a patients’ visceral fat that is often linked to a higher risk for cardiovascular risk. By using this method, doctors cannot determine how much of a patient’s body is muscle or fat.
On the other hand, body composition analysis differentiates between a patient’s muscle, fat, and water levels. Studies have proven InBody DSM-BIA body composition analyzers are an effective tool for treating patients with cardiovascular disease and improving surgical outcomes. InBody devices ensure cardiology professionals can be certain that the outputs generated accurately reflect changes within the patient.
In less than 60 seconds, cardiology professionals receive an InBody Result Sheet (body composition printout) that can aid in:
- Obtaining objective fluid measures and guide fluid management strategies
- Effectively monitoring nutrition status and guide nutritional interventions
- Accurately tracking patient progress and predict surgical outcomes
Monitoring Edema Improves Patient Outcomes
“EI determined by BIA is a useful predictor of the amount of weight reduction needed to reach dry weight…in HF patients.”
Yamazoe et al., 2015
Dangers of Visceral Fat
“…a significantly higher percentage of participants with VFA ≥100 cm2 had diabetes, obesity, hypertension, hypertriglyceridemia and hypo-HDL cholesterolemia.”
Hancu et al., 2015
Importance of Phase Angle
“Preoperative low PA is an accurate marker of malnutrition and an independent predictor of adverse postoperative outcomes…We recommend using it to detect malnutrition in the cardiac surgery population.”
Ringaitiene et al., 2016
Assess cellular health to assess surgical risks and outcomes
Phase angle, a measure of how the cells respond to the electrical currents used to measure body composition, reflects cell membrane integrity and has been linked to survival in various oncological populations. When cells are healthy, they are better able to resist these currents utilized by the InBody, resulting in a higher phase angle.
Monitor nutritional status of cardiac patients
Phase angle reflects changes in cellular health that occur before the onset of cardiac cachexia or circulation issues. Monitoring of changes in phase angle is not only used to track patient status but is closely linked to surgical risks and outcomes in cardiac patients.
By assessing these outputs over time, a patient’s nutritional status can be monitored as they progress through a rehabilitation program and complications related to interventions or surgeries can potentially be avoided.
Improve quality of cardiac rehabilitation
After a cardiac event, patients often undergo rehabilitation, consisting of health education, nutrition counseling, and exercise training, to improve cardiovascular health and reduce the risk of recurrence. However, cardiac rehabilitation programs rely on BMI as a marker for change in nutritional status even though it is not an effective method for tracking changes in body composition and health status.
Ability to develop individualized treatment plans
By using InBody, professionals can monitor a patient’s muscle-fat balance to guide nutritional interventions and track progress throughout the rehabilitation program. InBody measures of lean mass and Edema Index can further aid in the assessment of muscle loss that may be masked by increase fluid retention.
InBody provides the patient a more accurate representation of their muscle and fat balance with percent body fat while also tracking changes in muscle, fat and fluid over time through the Body Composition History section. This chart provides an educational outline to start discussion towards lifestyle change and can guide nutritional interventions as well as monitor exercise progress through rehabilitation programs. Patients are provided a visual representation of progress to stay motivated while professionals are able to make adjustments to their programs as needed.
Segmental ECW/TBW Water Analysis
Assess fluid balance in each body segment
InBody provides an Edema Index, the precise measurement of the ratio of extracellular to total body water. Monitoring the Edema Index (ECW/TBW) provides an assessment of fluid accumulation in the extracellular space resulting from compromised cardiovascular function. The Edema Index reflects changes in cardiac and circulatory function, underlying circulation issues, and the effectiveness of diuretics. By using the Edema Index to assess fluid balance, cardiology professionals can develop more effective fluid management strategies to improve patient outcomes.
Diagnose circulation issues
In addition to Whole Body ECW/TBW, Edema Indices specific to each segment of the body (arms, legs, and trunk) indicate where region-specific fluid imbalances may be occurring. The arms and legs can be monitored separately to identify circulation issues in the extremities, and truncal edema, which is often the most difficult to identify, can now be quantified and monitored.
Why do cardiologists trust InBody?
All InBody professional body composition analyzers rely on four pillars of technology to deliver quick, accurate and precise results. These pillars allow you to trust that the results reflect your patients’ true health from the inside out.
Direct Segmental Measurement (DSM)
Direct Segmental Measurement (DSM) measures water, muscle mass and fat mass in five body segments: right arm, left arm, left leg, right leg, and trunk. By measuring each segment of the body separately, the InBody is able to provide an in-depth analysis of a patient’s fluid balance in each segment independently. These outputs include intracellular water, extracellular water, and ECW/TBW ratio. Segmental Edema Index ratios reveal circulation issues that can result from blood clots or other health conditions, while separate measures of intracellular and extracellular water allow for the monitoring of nutrition status and intervention success.
InBody devices utilize multiple frequencies to measure body water more accurately than commonly-used methods such as weight changes or pitting edema scores. These high and low frequencies are able to measure both intra- and extracellular water, producing more precise measurements of body water compartments. Having an accurate measure of the different water compartments can indicate fluid imbalances or water retention stemming from circulation issues and can be used to monitor changes in fluid balance following diuretic use.
8 Point Tactile Electrodes
InBody devices use 8-Point Tactile Electrodes to ensure that measurements always start in the same place, test after test. This technology creates precise and reproducible results, ensuring the results professionals are seeing are genuine changes happening to their patient and are not due to error.
No Empirical Estimations
InBody devices do not rely on empirical estimations to predict results. Empirical data such as age, gender and ethnicity does not change an individual’s results, an important factor for cardiology professionals as heart failure affects each patient differently. By not relying on pre-loaded data, cardiology professionals know that the data they are obtaining on their patient is based on that patient alone. Therefore, any changes that are happening to a patient reflects a genuine change in their body composition.
