What Is the Real Cause of Heart Disease?

Now we know what is the real cause of heart disease according to a heart surgeon who recently wrote an article on the internet about this extremely important and delicate subject.

The author, Doctor Dwight Lundell is an experienced heart surgeon who claims he has gained an understanding of the underlying cause of atherosclerosis and coronary artery disease by looking at the inside of patient’s arteries. He has seen with his own eyes how the food we eat damages the inside of our arteries and causes inflammation.

What is the Real Cause of Heart Disease?

Lundell says: “I have peered inside thousands upon thousands of arteries. A diseased artery looks as if someone took a brush and scrubbed repeatedly against its wall. Several times a day, every day, the foods we eat create small injuries compounding into more injuries, causing the body to respond continuously and appropriately with inflammation”.

Thousands of people have read Dr.Lundell’s article on the internet. People like what he writes. Why is that? Is it because he is a bearer of the truth? Is it because he is a reliable scientist? Is it because he knows what has to be written to gain popularity? I leave it to you to judge for yourself.

News agencies around the world have presented Dr. Lundell’s article with the agenda that it’s about someone who had the courage to speak the truth. “Heart surgeon speaks out on what really causes heart disease.” People love to read about heroes and those who dare.

For decades scientists have been trying to understand the relationship between heart disease, cholesterol, and inflammation. Recent evidence indeed suggests that inflammation may be a major contributor to cardiovascular disease. However, the so-called inflammatory hypothesis has yet to be proven. There are several ongoing trials aiming to test it. Until we have the results, nobody can claim to know the answers.

How can Dr. Lundell see the cause of atherosclerosis with his own eyes in the operating room by looking at the inside of patient arteries? How about all the other surgeons who have had the same view? Why haven’t they had the same vision?

How about all the scientists in the laboratories around the world who are trying to understand and define the atherosclerotic process, the role of cholesterol, cholesterol crystals, apolipoproteins, lipoprotein particles, oxidation, cytokines, macrophages, and inflammation. Why haven’t they seen the same thing as Dr. Lundell by looking at the inside of the artery?

Going against mainstream is not easy, and you need a lot of courage to do it. People who dare think outside the box have often made significant contributions to medicine.

However, if you are going to challenge mainstream medicine and the current beliefs of the scientific community you must do it professionally. You must be sure you are standing on solid ground. You must have concrete arguments. Otherwise, your words will sound hollow and worthless. Unfortunately, Dr. Lundell sounds like a false prophet.

So, why do I feel Dr. Lundell sounds more like a false prophet than a scientist? Let’s take a closer look at his arguments.

Dr. Lundell touches on some important subjects in his article. And sometimes he’s probably spot on. For example, it is quite likely that cholesterol lowering drugs are overused in primary prevention. It is also possible that overeating of unhealthy, processed carbohydrates has contributed to the obesity epidemic. Maybe our emphasis on cholesterol and saturated fats has been too strong, and maybe saturated fats are not the enemy.

He starts his article by trying to convince the reader that he is trustworthy. His credibility is important if we are to believe his ideas about what is the real cause of heart disease. The reasons why we should believe what he says are twofold. Firstly, he is a heart surgeon with more than 25 years experience. Secondly, he is an honest person because he admits he was wrong in the past. So people may think: “Thank god. An honest doctor at last. Someone who dares to speak out”. But, revealing your honesty isn’t always honest. But I guess it means that if he turns out to be wrong, he will be the first one to admit it.

Dr. Lundell states: “The discovery a few years ago that inflammation in the artery wall is the real cause of heart disease is slowly leading to a paradigm shift in how heart disease and other chronic ailments will be treated.”

Although I think he is far ahead of himself, he actually touches on an important issue. Recent research indicates that inflammation may play an important role in atherosclerosis and cardiovascular disease in general.

There is tremendous research ongoing to understand the link between inflammation, cholesterol and heart disease. However, although inflammation seems to be an important component of atherosclerosis, it has yet not been proven that it is a causative factor. We still don’t know whether prognosis will be improved by inhibiting or preventing inflammation.

Dr. Lundell states that 25% of the population are taking cholesterol-lowering drugs (statins). I do not know of any country where the use of cholesterol-lowering drugs is that high. In the United States, the number of people taking these drugs is somewhere between 15-30 million. Although this is a very high number, it does not exceed 10% of the population. I wonder where Dr. Lundell gets his statistics from. It has indeed been suggested that among individuals aged 45 and older in the USA, about 25% may be taking statins. I will be the first one to admit that this is a high number.

Dr. Lundell writes that without inflammation, cholesterol might not be harmful at all. This time he might be spot on. In fact, cholesterol may play an important role in inducing inflammatory responses in the arterial wall.

Thus, without cholesterol, there would probably be no inflammation and no atherosclerosis. Therefore, it is quite likely that cholesterol and inflammation both play an important role in cardiovascular disease.

He writes: “It is inflammation that causes cholesterol to be trapped.” Here Dr. Lundell s certainly underscoring the importance of cholesterol. However, elsewhere in the article, he writes: “Since we now know that cholesterol is not the cause of heart disease….”.

The inconsistencies in his somewhat opinionated arguments are quite stunning. Maybe he should have written: “Since we now know that cholesterol is not the sole cause of heart disease…”

In fact, inflammation is very complicated. Scientists have for many years been doing ambitious and complex research to understand the mechanisms behind inflammation and atherosclerosis. Lately, we have been gaining important information about cytokines and other mediators of inflammation. These mechanisms are not simple.

Dr. Lundell says: “The injury and inflammation in our blood vessels are caused by the low-fat diet recommended for years by mainstream medicine.”

This is a huge statement. Where is the scientific evidence behind this serious conclusion?

Dr. Lundell claims there is a lack of evidence indicating that saturated fats promote heart disease and he could be right about that. There are however studies available showing that monounsaturated and polyunsaturated fats may be a healthier food choice than saturated fats.

His statement that polyunsaturated fatty acids are likely to cause inflammation is in my view an oversimplification. This subject is a matter of debate. Both omega-3 and omega-6 polyunsaturated fats are important for health.

Finally, I tend to agree with Dr. Lundell when he recommends choosing the foods your grandmother served and avoid manufactured foods. Fresh, unprocessed foods are usually a better choice.

Dr. Lundell’s article has received enormous attention, and it has caught the eye of the news media. It touches on some important issues regarding cardiovascular disease in general.

To me, the article, unfortunately, appears like it is written by a preacher or a politician who has to sell a message whatever the costs. The article lacks the professional approach of a scientist who carefully examines available scientific data before drawing conclusions.

I can’t help but wonder what his motives are.
