DR.DEAN ORNISH PROGRAM FOR REVERSING HEART DISEASE PDF

Get Started Or call Our approach to nutrition is all about feeling good, experiencing a joy of living, not a fear of dying. When you eat this way, you will lose weight and gain health. We also found that changing lifestyle changes your genes—turning on protective genes and turning off genes that promote inflammation, oxidative stress, and oncogenes that promote prostate cancer, breast cancer, and colon cancer—over genes in only 3 months. In addition, these lifestyle changes lengthen telomeres, the ends of our chromosomes that regulate aging, thereby beginning to reverse aging at a cellular level.

To buttress these claims, they will cite the studies of Esselstyn , Pritikin , and Ornish. I've previously discussed the bad science underlying the programs of Esselstyn and Pritikin but have only briefly touched on the inadequacy of Dean Ornish's studies. The Ornish website proclaims it the first program "scientifically proven to undo reverse heart disease.

If it were true, wouldn't the Dietary Guidelines for Americans, the American Heart Association, and most cardiologists and nutrition experts be recommending it?

Dean Ornish has an MD degree from Baylor College of Medicine and trained in internal medicine but has no formal cardiology or nutrition training although many internet sites, including Wikipedia, describe him as a cardiologist. Ornish, according to the "Encyclopedia of World Biographies," became depressed and suicidal in college and underwent psychotherapy "but it was only when he met the man who had helped his older sister overcome her debilitating migraine headaches that his own outlook vastly improved.

Under the watch of his new mentor, Swami Satchidananda, Ornish began yoga, meditation , and a vegetarian diet, and even spent time at the Swami's Virginia center. Claims on the program's website are based on a study he performed from through that originally had 28 patients with coronary artery disease in an experimental arm and 20 in a control group.

You can read the details of the 1 year results here and the 5 year results here. There are so many limitations to this study that the mind boggles that it was published in a reputable journal. These include:. While patients with significant coronary lesions from coronary angiography were "identified," only 93 "remained eligible. Somehow, this randomization process assigned 53 to the experimental group and 40 to the usual-care control group.

If this were truly a randomization the numbers would be equal and the baseline characteristics equal. Only 23 of the 53 assigned to the experimental group and only 20 of those in the control group agreed to participate. In other words, all of the slackers were weeded out of the experimental group and all of the patients who were intensely motivated to change their lifestyle were weeded out of the control group.

Gee, I wonder which group will do better? Needless to say, this was not blinded. The researchers definitely knew which patients were in which group. Control-group patients were "not asked to make lifestyle changes, although they were free to do so.

There is very little known about the 20 slackers in the control group. I can't find basic information about them -- crucial things like how many smoked or quit smoking or how many were on statin drugs.

Progression or regression of coronary artery lesions was assessed in both groups by quantitative coronary angiography QCA at baseline and after about a year. QCA as a test for assessing coronary artery disease has a number of limitations and as a result is no longer utilized for this purpose in clinical trials. When investigators want to know if an intervention is improving coronary artery disease, they use techniques such as intravascular ultrasound or coronary CT angiography see here which allow measurement of total atherosclerotic plaque burden.

Rather than burden the reader with the details at this point, I've included a discussion of this as an addendum below. The minimal diameter meaning the tightest stenosis changed from 1. At 5 years, the minimal diameter had increased another whopping 0. In other words, even if we overlook the huge methodologic flaws in the study, the so-called "reversal" was minuscule. There were no significant differences between the groups at 5 years in hard events, such as heart attack or death.

There were fewer stents and bypasses performed in the Ornish program group, but the decision to proceed to stent or bypass is notoriously capricious when performed outside the setting of acute myocardial infarction. The patients in the experimental group under the guidance of Ornish and his program counselors would be strongly motivated to do everything possible to avoid intervention. I've gotten a lot of flack for humorously suggesting that Nathan Pritikin killed himself as a result of the austere, no-fat diet he consumed, but the bottom line on any lifestyle change is both quality and quantity of life.

If you are miserable most days due to your rigid diet, you might consider that life is no longer worth living. Although often cited as justification of an ultra-low fat diet, the Ornish Lifestyle trial didn't test diet alone. It was a trial of multiple different interventions with frequent counseling and meetings to reinforce and guide patients.

The interventions included things that we know are really important for long-term health: regular exercise, smoking cessation, and weight management. These factors alone could account for any differences in the outcome but they are easily adopted without becoming a vegetarian.

The patients who agreed to the experimental arm were clearly a highly motivated bunch who agreed to this really strict regimen. Since investigators clearly knew who the "experimental patients" were and they were clearly interested in good outcomes in these patients, there is a high possibility of bias in reporting outcomes and referring for interventions.

Despite all the limitations, the study does raise an interesting hypothesis. Should we all be eating vegan diets? If Ornish really wanted to scientifically prove his approach, he should have repeated it with much better methodology and much larger numbers.

It most certainly doesn't show that the Ornish Lifestyle Program "reverses heart disease. A recent paper on noninvasive assessment of atherosclerotic plaque has a great infographic which shows how coronary artery disease progresses and how and when in the progression various imaging modalities are able to detect plaque:.

I've inserted a vertical red arrow which shows how IVUS detects very early atheroma whereas angiography ICA, green line only detects later plaque when it has started protruding into the lumen of the artery. The paper notes, "Intravascular ultrasound IVUS constitutes the current gold standard for plaque quantification.

Multiple studies using IVUS and other techniques have revealed a robust relation between statin therapy and plaque regression. A meta-analysis of IVUS trials including 7, patients showed an association between plaque regression and decreased cardiovascular events. While I believe Ornish started off as a legitimate scientist, several authors have pointed out that he has joined the ranks of pseudoscientific practitioners. Here's one analysis from Science Blogs :. Ornish has yoked his science to advocates of pseudoscience, such as Deepak Chopra and Rustum Roy.

Why he's done this, I don't know. The reason could be common philosophy. It could be expedience. It could be any number of things. By doing so, however, Dr. Ornish has made a Faustian deal with the devil that may give him short-term notoriety now but virtually guarantees serious problems with his ultimately being taken seriously scientifically, as he is tainted by this association.

Let me yet again reemphasize that this relabeling of diet, exercise, and lifestyle as somehow being "alternative" is nothing more than a Trojan Horse. Inside the horse is a whole lot of woo, pseudoscience and quackery such as homeopathy, reiki, Hoxsey therapy , acid-base pseudoscience , Hulda Clark's "zapper," and many others Anthony Pearson, MD , is a private practice noninvasive cardiologist and medical director of echocardiography at St. Luke's Hospital in St. He blogs on nutrition, cardiac testing, quackery, and other things worthy of skepticism at The Skeptical Cardiologist , where a version of this post first appeared.

Prevention Magazine: Two Features Dedicated to Preventing Heart Disease and The Ornish Program

Wellness Articles. Is it only a matter of time before you have another heart attack or cardiac issue? According to researchers and dieticians, the answer is no—heart disease can be reversed, and one of the best ways to reverse heart disease is through cardiac rehabilitation. In these sessions, a care team teaches you how to manage stress, be conscious of how much you exercise, help maintain a heart-healthy diet and offer support. The diet has gained popularity in the last 30 years because participants averaged losing 24 pounds and most kept the weight off—something uncommon for other major diets, and helping get rid of a major risk factor for heart disease. While on the diet, avoid all meats, oils and sugars. As a result, this puts less pressure on your heart.
