Evaluation – Assessment using CardioVision

Principle and Definition

CardioVision is a computer-based non-invasive system with the ability to determine Ankle Brachial Index (ABI) for assessment of lower extremity stenosis and Arterial Stiffness Index (ASI) for assessment of the degree of arterial stiffness using the oscillometric method.

Excessive stress and lack of exercise are known health risk factors that trigger progression of certain life-threatening diseases. CardioVision provides an opportunity to assess such risk factors.

ASI assessment with CardioVision is based on measurable physiological phenomena observed from the elasticity and hardness of the artery using pressure and volumetric changes. The principle of ASI measurement was established following a proposal by Professor Hideaki Shimazu at Kyorin University, and CardioVision is the original and peerless device.

CardioVision is the product of more than two decades of intensive research. Its method of measuring can be easily applied in almost all medical fields. CardioVision provides an opportunity to manage the effect of health enhancement strategy.

How to Measure

CardioVision measures blood pressure and pulse wave using cuffs wrapped around the extremities in the supine position and calculate ABI and ASI. The measurement will be completed in approximately 9 minutes. The results will be recorded in the Software, and ABI and ASI will be calculated.


Assessment using CardioVision

Principle and Definition

CardioVision MS-2000 offers Ankle Brachial Index (ABI) and Arterial Stiffness Index (ASI) as indicators for assessment of arterial stiffness for healthcare professionals. These measurements allow speedy and objective analysis of vascular function. Such data can provide valuable information to healthcare professionals.
(Data may be used to determine whether to start treatment in a patients without any noticeable symptoms or clinical signs.)

While a healthy heart efficiently supplies oxygen and nutrients throughout the body, it also sends waste to the kidneys, liver and lungs for removal. For this to occur, arteries must be in good condition. Arteries may become atherosclerotic, arteriosclerotic or stiffened (due to reduced elasticity and increased stenosis) over time. These changes will cause strain on the heart, valves and arteries, which may cause stroke, heart attack, renal failure and/or sudden death.

About ABI

ABI is an index to assess peripheral arterial diseases (PAD) such as stenosis/occlusion of leg arteries. It is calculated by dividing systolic blood pressure of the right and left ankles by that of upper arm (right or left, whichever higher).

About ASI

ASI measures whether the vascular system is functioning normally without any limitations due to health risks. Arterial stiffness due to medial calcification and reduced elasticity caused by aging is the most critical factor contributing to increase in ASI. Unlike other measuring principles for arterial stiffness, ASI allows efficient assessment of arterial stiffness directly under a cuff, thus making it e a useful index for assessing arterial stiffness in each extremity.


CardioVision offers useful data for diagnosis of PAD. PAD is one of the major factors for poor prognosis. Based on the unique index ASI, CardioVision can also measures simultaneously and displays the condition of PCA due to medial thickness which affects prognosis more than PAD.


CardioVision is very user-friendly and intuitively operable for both health professionals and related care providers. Due to its simple hardware and standard computer requirements, CardioVision can be smoothly incorporated into virtually any of medical- and health-related facilities such as clinics, laboratories, health clubs and wellness centers.
CardioVision can also be used easily in regular health checkups. Assessment results may be used in regular health maintenance, or monitoring general health conditions or effects of various therapies to achieve intended health conditions. CardioVision helps in reducing the incidence of profession- or semi-professional work related diseases in affiliated staffs throughout the various departments of treatment.
