Measuring Your Heart Function

Recently I came across a book by Dr. Steven Masley, cardiologist (fellow of the American Heart Association, see Ref.1). The heart’s function is to pump your blood reliably all your life. It is a complicated organ, but it works well, if we treat it well. Western medicine has taught us that with complicated machinery and tests we can assess how the heart is doing. But until recently there was no reliable easier way to assess our cardiac health function. The purpose of this blog is to summarize a three-pronged approach to measure your heart and blood vessel health. It is described in detail in Ref.1, but I doubt that many people have yet read this important reference book. It is also important to FIRST see your doctor whether you are able to do the Bruce protocol (treadmill test, the third component below). If you neglect to be cleared by your doctor you run the risk of possibly getting angina pains or getting a heart attack.

1. Carotid IMT or carotid intimal-medial thickness test: You measure the degree to which there is hardening of the coronary arteries indirectly by measuring the thickness of the lining of the carotid arteries (carotid IMT or carotid intimal-medial thickness test). Dr. Masley has showed over a period of 10 years and more in many patients at his Health Center that there is a close correlation between the degree of coronary artery hardening and the degree of hardening of the carotid arteries. He stated that his research has shown that “90% of the time, the carotid arteries, the coronary arteries, and even the arteries of your legs all grow plaque at the same time”. The gold standard for checking the condition of your coronary arteries is a heart catheterization as Dr. Masley explains (page 58). But he adds: “IMT testing should be the new gold standard for cardiovascular plaque testing. However, this is not yet the case. Despite its usefulness, 95% of doctors are not ordering this screening test for their patients. You can rest assured that this is a situation I am to change“.

2. A detailed lipid analysis called the VAP test: A detailed laboratory test analyzing your lipid fractions (LDL, HDL, total cholesterol and VAP test). The buoyant HDL fraction, called HDL2 is the key to having a low risk for hardening of the arteries. HDL2 is large, fluffy and is designed to remove garbage from within the lining of the arteries. Also, the cholesterol ratio is another measurement for a low risk for hardening of the arteries when it is less than 3.0. The first two tests assess how much hardening of the arteries there is present and when they are normal, there is a relative reassurance that nothing drastic (like a heart attack or stroke) should happen within the next 10 years provided you keep up a regular exercise program and healthy food intake.

3. Bruce protocol (Treadmill test): The Bruce protocol (treadmill test) is often done by a cardiologists, but can also be done through many gyms, where a trainer with experience in exercise physiology will do it. This functional test measuring cardiac output has been developed many decades back and has withstood the test of time. Here is an overview what this is. As the slope of a treadmill and the speed of the belt are increased, the heart needs to do more work to maintain blood flow to your extremities and vital organs. The trainer or exercise physiologist measures the response of the heart activity in relation to the increase of the exercise load. A complicated formula allows calculating how much your maximal cardiac output is. This test has several variations and can be complicated to understand. Essentially, the higher the numbers you can create, the better. Here is a table with various results of the VaO2max from Bruce protocols and how they are interpreted.

4. Treating abnormalities found with the three basic tests: These are the necessary tools that tell you where you are in regard to your heart function. People with heart failure should not do this third test, because their heart muscle is too weak to sustain this and they would get heart failure meaning that blood gets backed up into the lungs and there could be severe breathing problems leading to a lack of oxygen (anoxia) in the heart tissue, which in turn can cause irregular heart beats (fibrillation of the heart muscle) and a heart attack. Assume that the first two tests were within the normal limit for your age, then the Bruce protocol would give you the maximum heart output at the peak level of your treadmill test. At this point you are measuring directly the cardiac output (in other words what your heart is capable of pumping for you in a certain time unit). This measurement is what physicians call the VaO2 max  or maximal oxygen consumption. This is the best index for maximal heart capacity. If your levels are higher than normal, you have extra reserves with respect to your heart as a pump for times when you need it. If this latter tolerance test shows poor results, it usually means that you were inactive and you would benefit from an exercise program. If the first test shows hardening of the arteries more than is appropriate for your age, you would need to look at your eating habits. At the same time often the VAT values and the cholesterol ratio is off meaning that you are eating the wrong foods and it shows in your blood test results.

5. Advise regarding diet, exercise and relaxation: Dr. Masley’s book has several sections that explain what needs to be done when things are not normal. For instance, the author does not mince words when it comes to eating the right fats and cutting out sugar and starchy foods. For instance on page 199 there is a neat table that lists the fiber content of different foods. We need more fiber to slow down the absorption of sugary substances, which will minimize the insulin response following a meal. Dr. Masley also mentions that omega-3-fatty acids from fish and good seafood choices will balance the omega-6-fatty acids that would lead towards the arachidonic acid pathway, which causes arthritis, inflammation and cancer. There are many more dietary recommendations, too numerous to repeat them all here. Suffice it to say that molecularly distilled omega-3 fish oil, vitamin D 1,500 to 3000 Units daily, and magnesium supplements are all good for you heart. Vitamin K2 gets calcium out of your blood vessels and into the bone (100 micrograms per day). Other worthwhile supplements mentioned in the book are CoQ-10 (50 to 200 mg twice per day), but it would be wise to have blood levels drawn, which should be above 2.5mcg/ml to which the CoQ-10 intake could be titrated. Curcumin and Resveratrol are also recommended. Most of all, it seems that regular physical exercise such as a balanced gym program is the single most effective way to reverse hardening of the arteries as measured by the carotid IMT testing.

Conclusion: Times have changed. It used to be thought that our lives were following a one-way street downwards. During periods of malnutrition, lack of exercise, being sessile and abusing alcohol and drugs this may well be the case. However, we now know that this is reversible. Change to healthier food, start smoothies with organic vegetables in a mixer, get going and walk. Jog or use a gym to get regular exercise. Physical exercise reverses the fat deposits inside the lining of the arteries. The HDL-2 fraction rises and helps counteract the elevated LDL cholesterol. Even the mood of the person who exercises regularly becomes more stabilized. Using these simpler three tests the physicians will not need the more complicated Thallium heart scans, heart catheterization etc. These three tests described above are well worth being done every two years, so that you can monitor what’s going on with your heart and blood vessels in general. What questions do you have? You could ask them below.

From Inflammation To Heart Attacks, Strokes And Arthritis

This article describes the development from inflammation to heart attacks, strokes and arthritis. Have you ever wondered why people who limp from arthritis in their hip also often get heart attacks? And have you ever wondered why people with high blood pressure get strokes and/or heart attacks? It is not that difficult to understand, although many people do not like to hear the truth. After the holidays with lots of sweet presents and rich food it is a good time to reflect about the internal connections between our organs. Let’s follow what foods can do to our system, then you will understand what to do to get out of the rich food trap, where food is not friendly but damaging to your body.

1. Sugar, omega-6 fatty acids and trans fats enter your system

When you opened the cheap chocolate bars, ate the pastas, the turkey gravy and the ice cream for dessert, your stomach faithfully digested all that food and broke it down into glucose (a simple sugar), omega-6 fatty acids and highly reactive trans fat with free radicals (from deep fried foods, margarine, shortening, pie crusts, cake mixes, frostings and non dairy coffee creamers just to mention a few).  Within ½ hour the sugar molecules from the digested meal will enter your blood stream.

2. The metabolism sets in

We know from years and years of research that the glucose in the blood triggers the release of insulin from the pancreas, which facilitates absorption of sugar into your liver and muscles where it is stored as glycogen. This is meant to be a storage form of sugar, just in case you do not eat for a few hours, but need energy to burn for your physical activity. When you have saturated the glycogen storage in liver and muscles, your liver metabolizes sugar into fatty acids and triglycerides. There is the transport LDL cholesterol that is supposed to supply the brain and heart with healthy cholesterol for these organs to replace cell membranes.

Oxidized LDL cholesterol attacks your arteries

Instead, the LDL cholesterol that is supposed to be balanced by the protective HDL cholesterol gets oxidized from the extra sugar and from the free radicals of the TRANS fats that are now being outlawed by the FDA for exactly that reason. So, the oxidized LDL cholesterol turns into the vicious VDLDL particles, which can be measured as a special blood test by your doctor. The overabundance of omega-6 fatty acids start an internal fire by stimulating the arachidonic acid pathway, which causes inflammation in your arteries, your joints and your immune system.

3.  The consequences of eating foods which spike your blood sugar levels

The end result is hardening of your arteries and the beginning of arthritis in your joints. Mind you, this does not happen overnight, but when you eat this way decade after decade it takes its toll. Typically in your forties or fifties you will notice some swollen knuckles. Don’t just let this happen. Think that this is a sign that something is festering in you! If you don’t interfere, there could be one wrong move, when you play sports and a meniscal tear in your knee could put an end to the fun. Sure, you will find a reason that the angle of your jump was unfortunate and this was simply enough for your meniscus to tear.

Inflammatory changes in the meniscus

But could it be that there were inflammatory changes in your meniscus long before this incident, the meniscal material softened up, dried up because of a lack of proper nourishing synovial fluid? I found when I was in primary care practice that this was what caused the majority of meniscal tears. A normal meniscus does not tear easily, but decades of malnutrition will lead to these hidden changes, where a meniscus can be softened and is prone to damage without a warning.

Arthritis in your joints is similar to the process of what I described regarding meniscal degeneration. An imbalance of the omega-6/omega-3 ratio where people take in 12 to 16 times as much omega-6 fatty acids from processed food compared to omega-3 fatty acids from fish oil or fish consumed, causes inflammation of the joints via the arachidonic acid metabolism.

Calcifying arteries in patients with vitamin D and K2 deficiencies

What about the arteries? It is no secret that many people in their 60’s have suddenly an episode of chest pain that leads to a referral to a cardiologist who will do a heart catheterization. The physician may have to place a stent or two because of hardening and narrowing of the coronary arteries. In many trials where people with coronary artery disease were followed laboratory tests showed that these individuals had low 25-hydroxy-vitamin D levels in their blood and the calcium that was meant to make their bones strong, ended up in the arteries. Vitamin K2 is often also missing because of malnutrition.

Faulty diet and lack of regular exercise can cause coronary artery hardening

People with high blood pressure often do not have enough nitric oxide production from their arteries, because they do not eat enough vegetables, they are too sessile and they eat too many sweets and starchy foods. As a result, the liver overproduces triglycerides and fat, and oxidized LDL cholesterol damages the lining of the arteries. Just treating high blood pressure with blood pressure lowering medications will not correct the underlying metabolic disbalance. This is why people who had 2 or three stents for coronary artery hardening will come back 5 or 10 years later and need more stents until they die of a full-blown heart attack. You must stop the underlying metabolic derangement, if you want to prevent further deterioration.

4.  Inflammation takes its toll

But what do the lining of the arteries, the inflamed joints, a degenerative meniscus and heart attacks and strokes have in common? It is the INFLAMMATION that changes the body chemistry. It gets even more complicated, because the extra calories that we consume get stored as visceral fat. This is done automatically when you eat too much sugar and starchy foods as you may have done over the holidays. Remember, our ancestors were hunters and gatherers, and our genetic make-up is still the same. So, when the glycogen stores are full, any surplus sugar gets metabolized by the liver into triglycerides, fatty acids and LDL cholesterol and gets stored as body fat.

The most active fat is the visceral fat

The most active fat is the visceral fat between our guts and around our body organs. This produces interleukins and other inflammatory cytokines that circulate in the blood causing inflammation in all our arteries.

This is the link between the various manifestations of inflammatory conditions in our bodies. We rarely think that there is a link between all of these various conditions. Physicians concentrate on each disaster as it strikes, but think that it is only a one-point-in-time event. Patients do not see the years of abuse of our bodies that have preceded any of these events.

5.    Disaster strikes in different ways

We usually hear about a person who just got a heart attack. Now it is an emergency!  Nobody thinks about the years of inappropriate food intake and the lack of exercise that led up to this heart attack event.

The same is true for a sudden stroke. The patient arrives at the hospital in an ambulance and cannot move one arm and one leg. Initially the patient may be unconscious. The emergency personnel is too busy with medical procedures, so they cannot ask the question why it had to come to this. The truth though is that the blood vessel deterioration in the brain vessels that led to the stroke have quietly happened years before the acute event.

Arthritis in older patients

And then there is the aging 75-year-old man with a stiffening hip and arthritis in the hands. The inflammation has been quietly developing in the synovial membranes of the joints for more than a decade. The patient probably swallowed anti-inflammatory medications for years for arthritis symptoms, which as you guessed has not changed the underlying biochemistry. But now it has come to the point where a total hip replacement is necessary, just to be able to continue to walk. I have experienced that scenario in the hospital setting many times. Many patients went through the total hip replacement surgery with no problems.

Some patients develop a heart attack during their surgery for a total hip replacement

But other patients had their total hip replacement done and they developed a heart attack under the general anesthetic. Unbeknown to the orthopedic surgeon the patient also had severe hardening of the arteries. However,  this did not show up on the pre-surgical electrocardiogram. A stress test or a Thallium heart scan when the patient still could exercise would have shown this hidden cardiac condition before the surgery, so that a cardiologist could have addressed this condition before the surgery. After that the total hip replacement would most likely have been uneventful.

6. Prevention is the key

The lesson we need to learn from all of this is: prevent these disasters from happening in the first place. Do the following:

1) Good, balanced nutrition

2) Regular exercise.

3) Take vitamins and mineral supplements for bone health.

4) As you age, have your hormones measured and replace what is missing.

5) Avoid toxins. Use detoxification.

6) Avoid junk foods.

I have covered these topics in many blogs before as indicated in the above links.

Conclusion

Health disasters are mostly not accidental. Rather they originate by not paying attention to the silent metabolic changes due to improper nutrition. In addition, a lack of exercise is important as well.  You can call this a lack of prevention. It takes some time, often even some suffering to understand the deeper meaning of what I discussed above. In the final analysis prevention is much more powerful on the long-term than curative medicine. I speak from experience having worked in the medical field for more than 30 years. Curative medicine will take care of an emergency. However, the underlying inflammation and metabolic derangement persists, if the physician cannot change this through the steps mentioned above. Treat inflammation and LDL oxidation by modifying your lifestyle. Think prevention!
