The Meridian DPA: An Overview
60 Second DPA Arterial Testing
A Powerful New Tool for Healthcare Professionals
As a healthcare professional using the DPA, you have a powerful new tool and advanced technology providing you with cardiovascular parameters specific to the health of your patient's arteries.
In minutes, an easy to understand printout is available for identifying cardiovascular disease risk in your clients.
"I practice in a multidisciplinary center focusing on patients with chronic and degenerative conditions. Many of these patients have exhausted traditional medical treatment options as well as their insurance. Therefore, cost effective and easily administered in office testing is important. "
Why test for arterial elasticity?
"Aging and disease states associated with an increase in cardiovascular events alter the physical characteristics of blood vessel walls and impair the pulsatile function of the arteries. An accumulating body of evidence indicates that impaired pulsatile function of arteries provides important prognostic and therapeutic information beyond that provided by traditional blood pressure measurements." 2
"The ability to detect and monitor sub-clinical damage, representing the cumulative and integrated influence of risk factors in impairing arterial wall integrity, holds potential to further refine cardiovascular risk stratification and enable early intervention to prevent or attenuate disease progression."3
"Accumulating evidence suggest that abnormalities in the pulsatile characteristics of arteries occur early in the disease processes associated with increased cardiovascular risk, and can be favorably modified by therapeutic interventions."4
"We now know that the health of the endothelium and the blood vessels directly affects overall cardiovascular health. Cardiovascular disease kills 500,000 Americans every year in the form of heart attack and stroke. About 16 million more Americans suffer pain and disabilities caused by cardiovascular disease. Today, over 60,800,000 Americans (a quarter of the U.S. population) have one or more conditions that put them at risk for heart attack and stroke."5
The Printouts have information on:
The DPA provides information on arterial wall stiffness and determines the biological age of arteries in a 60 second Test. This FDA cleared, user-friendly, non-invasive device uses a finger probe to observe the changes in pressure, blood flow, velocity and profile throughout the whole pulse wave. Aging and disease states associated with an increase in cardiovascular events alter the physical characteristics of blood vessel walls and impair the pulsatile function of arteries. Accelerated Plethysmogram (APG) Waveform, the 2nd derivative of PTG is an excellent method to evaluate the biological age of arteries.
Cardiovascular disease is the #1 killer for both men & women in the United States with an estimated economic cost of over $300 billion.
Stress & Heart Rate Variability
Stress is the plague of our time, an epidemic that is spreading rapidly. Stress is one of the most important causes of high blood pressure, which afflicts one in three adults in Europe and North America and is the cause of many serious illnesses such as heart disease and stroke. Stress also lies at the basis of depression and burnout.
Heart Rate Variability (HRV) tests the balance of the autonomic nervous system using time and frequency domain analysis and provides early detection of psychological and environmental factors affecting health and causing stress.
Low HRV has been shown in numerous longitudinal studies to be related to a higher mortality rate in both healthy and unhealthy subjects. It thus can be shown to be a strong predictor of all-cause mortality. The heart is not just a simple pump, but a complex sensory organ with its own functional "heart brain" that communicates with and influences the brain via the nervous system, hormonal system and other pathways.
Research has shown that these influences profoundly affect brain function and most of the body's major organs. Science now confirms that stress significantly increases the risk of heart disease, including sudden cardiac death. Unmanaged emotional stress is equally if not more important than physical variables in determining health outcomes. A conservative estimate is that 75% of visits to primary care physicians are due to stress-related disorders.
Cardiovascular-related issues are not the only uses for the DPA. Psychologists are increasingly recognizing the importance of HRV. A number of studies have demonstrated that patients with anxiety, phobias and post-traumatic stress disorder (PTSD) consistently show lower HRV, even when not exposed to a trauma related prompt. Importantly, this relationship existed independent of age, gender, trait anxiety, cardiorespiratory fitness, heart rate, blood pressure and respiration rate.
