Digital Pulse Wave Analysis

AVP Report

Accelerated Vascular Plethysmography (AVP) assesses the state of health of the circulatory system. Long before clogged arteries develop, something known as vascular compliance becomes abnormal. Vascular compliance is simply a measure of the elasticity of blood vessels. By carefully measuring the timing, amplitude and shape of a pulse wave, it is possible to determine the vascular compliance of various parts of the circulatory system.

Specific markers tested by AVP:

•   Ejection time is a measure of the strength of the heart and the deficiency of the heart valves.
•   Pulse height is a measure of overall hydration.
•   APG type is a measure of vascular age.
•   EEI is a measure of large artery compliance.
•   DDI is a measure of small artery compliance.
•   DEI is a measure of arteriole capillary compliance. This is a measurement of endothelial health.

With Age Comes New Waves

As we age, circulation becomes less efficient, leading to build up of plaque in the arteries. The chart on the right demonstrates the change in wave patterns and the gradual build up of cholesterol, inflammatory cells, and fibrosis in arteries over time.

Listen to your heart.
It can save your life.

Heart disease, or more specifically coronary artery disease (CAD), is the leading cause of death in the United States in both men and women. Coronary artery disease begins with dysfunction of the inner lining of the blood vessels that leads to hardening of the arteries. Digital wave pulse analysis specifically measures stiffness or loss of compliance of coronary arteries. As the arteries stiffen, they become narrow and reduce blood flow to the heart. This reduces blood flow weakens the muscle of the heart. Additionally, a clot can form or “plaque” can rupture resulting in a heart attack. Over time, this poor blood flow can contribute to heart failure and even arrhythmias.
Risk factors for coronary artery disease include high blood pressure, smoking, diabetes, lack of exercise, obesity, poor diet, excessive alcohol, and other genetic risk factors. Depression is also a risk factor for coronary artery disease.
By assessing cardiovascular health and finding problems at an early stage, treatment to reverse the problem, and or prevent progression can be very effective. If this test suggests advanced arterial age, we may recommend a comprehensive assessment of biomedical risk factors and consider an advanced cardiac test called a multifunction cardiogram (MCG). By optimizing all known risk factors and adopting an heart healthy diet and lifestyle, you can save your heart and your life.
