Heart Attack Risk Screening Using Cardio-Metabolic Analysis

Did you know that you can screen for heart attack risk using cardio-metabolic analysis and provide that service for an affordable price to all your clients?  Cardio-metabolic testing can accurately, easily and non-invasively screen for blockages in a person’s heart, the key driver of cardio-vascular disease worldwide. The cardiovascular disease caused by blocked arteries is called coronary artery disease or ischemic heart disease. Artery blockages cause heart attacks. Cardiovascular disease claims the most lives every year and is the most costly disease in our healthcare system.  A heart attack costs between $700,000 and $1,000,000 in health care expenses, lost productivity and rehabilitation.  

How To Assess Heart Attack Risk With Cardio-Metabolic Data

In this video we will give you an overview of one of the most interesting applications of cardio-metabolic analysis.

As we discuss in other videos, cardio-metabolic analysis is the most reliable tool for building workout and diet plans. 

However, its utility can go way beyond that. Cardio-metabolic testing can accurately, easily and non-invasively screen for blockages in a person’s heart, the key driver of cardio-vascular disease worldwide.

Cardiovascular Disease Can Be Managed With Early Detection

The frustrating fact with cardiovascular disease is that it can be  effectively managed with early detection, medication and a few lifestyle interventions. In most cases, when blockages are detected early on, there is no need for surgery. 

The big problem for most heart attack victims is they never see it coming, thus the term “silent killer” for cardiovascular disease. They didn’t get warnings early enough to take action.  Common measurements like blood pressure and cholesterol can be normal and not provide any warning. Specifically, with nearly half of recorded heart attacks the individuals had normal blood pressure and cholesterol shortly before the attack. 

Standard Methods for Cardiovascular Disease & Heart Attack Risk Assessment

So the question that arises? Is there a way to effectively screen a person’s heart condition and take action accordingly? 

Unfortunately, EKG stress testing, the most frequently used method, only detects 50% of artery blockages. That means that you might have a blockage in your heart and there is a 50% chance that the EKG won’t detect it. 

Other options like nuclear imagining or ultrasound are either very expensive or involve radiation and can’t be used as early detection for most people. The ideal early detection tool would be highly accurate, inexpensive and would not entail sophisticated medical equipment or medical personnel. 

Cardio-Metabolic Testing is 90% Accurate 

The only method that is simple to execute, can be done outside the walls of a hospital, doesn’t require highly trained medical personnel and has a proven ability to detect blockages in a person’s heart with approximately 90% accuracy is cardio-metabolic testing.  It is nearly as accurate as sophisticated nuclear imaging methods and it can be done anywhere using just a stationary bicycle. 

A Stationary Bike Test for Cardiovascular Risk Screening

Lets see now how a simple bicycle test can provide deep insights into a person’s cardiovascular health, reveal the presence of a blockage in a person’s heart and evaluate heart attack risk. 

Before we analyze the cardio-metabolic profile of a person with coronary artery disease let’s first look at what is measured during a cardio-metabolic test:

  • VO2:  the volume of oxygen consumed by a person
  • Work rate:  the amount of mechanical power a person generates on the stationary bicycle.  This is the watts reading on the bicycle
  • O2 pulse:  the amount of oxygen consumed by the person divided by their heart rate. 

The Testing Process  – Known Artery Blockage 

Now let’s look at the cardio-metabolic profile of a person when there is an artery blockage. 

In this graph we see the cardio-metabolic profile of a patient doing a bicycle workout where exercise intensity is increased by 20 watts every minute. 

The black boxed line is the person’s oxygen consumption plotted against the power generated on the stationary bicycle. This line shows the person’s oxygen consumption as watts on the bicycle increase. 

On the right hand side graph we see the patient’s O2 pulse plotted with a white circled line as the watts on the bicycle increase. Also we see the person’s heart rate plotted with a black boxed line. This line  is the oxygen consumption for every heartbeat as the watts change when pedalling. 

How to Identify An Artery Blockage

On these two graphs we see 2 indications that denote the presence of an artery blockage:

  1. The first indication is the point where the VO2 line on the left hand side graph abruptly changed slope. This shows that oxygen consumption fails to increase and flattens even though exercise intensity increases. 
  2. The second indication is the fact that the flattening of oxygen consumption is accompanied by a flattening in oxygen consumption per heart beat, in other words flattening of O2 pulse, even though exercise intensity increases. 

Together these two trends show that after a specific exercise intensity the patient’s heart can’t  pump more oxygen to the working muscles. They can predict a heart artery blockage with approximately 90% accuracy. 

Why The Cardio-Metabolic Data Shows The Artery Blockage

Now lets see why these trends occur. The heart is a muscle and just like any muscle in the human body it requires oxygen to operate effectively. The blockage in the heart basically prevents a sufficient amount of blood from going into the heart so that it can operate effectively. As a result, after a certain exercise intensity the heart can now longer do its job effectively which is to pump oxygen rich blood into the working muscles. This is manifested as the plateau in oxygen consumption and oxygen consumption per heart beat. 

At the same time, what we expect to see is an abrupt increase in heart rate. This is a sign that the heart is trying to compensate for the reduced oxygen delivery. 

It is remarkable that a simple 10 minute test on a stationary bicycle can detect a blocked artery well before a heart attack occurs.  Especially when other methods may not provide any warning before the heart attack. 

The Cost of a Heart Attack vs The Cost of a Cardio-Metabolic Screen

The huge cost of a heart attack more than justifies the usage of cardio-metabolic testing to screen people at risk for cardiovascular disease. 

For self-insured private organizations, 1 heart attack can cost up to $1 million in health care expenses and lost productivity. 

With cardio-metabolic testing one can screen an organization of 10,000 employees at a cost of $100 per test, the cost of treating one heart attack.

As a result, by finding just one case of latent heart disease waiting to evolve into a heart attack, the entire cost of testing is has basically been paid off. 

And that doesn’t include all the other benefits of metabolic testing:

more effective diet and workout planning, and highly accurate health risk stratification.
