Quan Cardio


Transforming Early Detection of Heart Disease

Quantum BioTek’s scientists focus on the creating of a next-generation, powerful cardio diagnostic tool that helps reduce the incidence of cardiovascular disease in patient populations through early detection and prevention. 


QuanCardio is the first non-invasive intelligent medical device technology that assesses arterial stiffness through patented and proprietary finger clip technology. It enables a patient and front-line physician to detect heart disease much earlier, even in patients without symptoms, so that it can be treated before it’s too late. Using the information compiled from the patient, it can find clinical hints for early detection of disorders such as Arteriosclerosis, high blood pressure, peripheral circulatory disturbance and vessel aging status.

The QuanCardio Device is a front-line, low-cost mobile medical device to enable accurate, early diagnosis of heart disease. It has the potential to save millions of lives and billions of healthcare system dollars. The non-invasive medical device is designed to measure and detect a wide range of information on a patient's cardiovascular physiology in real time. Using LED sensors embedded in a finger probe, it utilizes the pulse wave velocity to measure the status of heart and blood vessels, arterial wall stiffness and biological age of arteries, among other factors. By accurately measuring the elasticity of small and large arteries, it provides patients and healthcare practitioners with critical information regarding arterial aging.

The integrated modular device incorporates sensor and signal processing systems with performance verification and optimization of algorithm and mathematical scheme in clinical tests over more than 10 year. 

Clinical Need

Cardiovascular disease generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke. 

Cardiovascular diseases claim more lives each year than all forms of cancer and chronic lower respiratory disease combined.

About 92.1 million American adults are living with some form of cardiovascular disease or the after-effects of stroke. 

Direct and indirect costs of cardiovascular diseases and stroke are estimated to total more than $316 billion; that includes both health expenditures and lost productivity.

The Importance of Prevention

Primary prevention refers to lifestyle and behavioral changes that can be made in the absence of any known coronary artery disease and before a heart attack. Tens of millions of people the world over fall into this category.

Some people think that heart attacks are an inevitable part of growing older. But there’s nothing inevitable about them and they are highly preventable. Regardless of your gender or age, you can dramatically reduce your chances of having a heart attack by getting a regular test and by dramatically improving lifestyle.

Secondary prevention refers to implementing the lifestyle and behavioral changes after a diagnosis of heart disease has been made. It is designed to halt further atherosclerosis development and prevent a second heart attack.
It also means undergoing interventions such as revascularization treatments—angioplasty, stenting, bypass surgery—when needed, and taking cholesterol-lowering drugs after a heart attack has occurred.


Each time the heart beats it induces a wave along the aorta and arterial tree.

This wave leads to blood volume changes in the vessels that expand and contract in response to these changes.

Diseases such as diabetes, cholesterol or high blood pressure induce stiff arteries, which lead to an elevated Pulse Wave Velocity and increased risk of cardiovascular disease. 

Pulse Wave Velocity is the propagation speed of this wave along the arteries. Increased stiffness of the arteries increases Pulse Wave Velocity. It allows to evaluate cardiovascular health. Medical research has demonstrated a strong correlation between the stiffness of the arteries and the risk of a cardiovascular incident. Stiffer arteries indicate a greater risk for high blood pressure, stroke, heart attack and heart disease.
