Thyroid Pills Prevent Heart Attacks by Jeffrey Dach MDThe Low Thyroid Condition and Heart Disease
In 1976 Broda Barnes was the first to connect low thyroid function with heart attacks and heart disease. His book is called, Hypothyroidism The Unsuspected Illness by Broda Barnes, Click Here to read my Book Review..

How did Broda Barnes discover the connection between low thyroid and heart disease? Barnes took summer vacations in Graz Austria every year to study the autopsy files. Graz had a high prevalence of thyroid disorders, and anyone in Graz who died over the past 100 years required an autopsy to determine cause of death, as mandated by the authorities. This rather large amount of autopsy data showed that low thyroid patients survived the usual childhood infectious diseases thanks to the invention of antibiotics, and years later develop heart disease. Barnes also found that thyroid treatment was protective in preventing heart attacks, based on his own clinical experience. Likewise for diabetes, Dr. Barnes found that adding thyroid medication was beneficial at preventing the onset of vascular disease in diabetics. Again, blood tests are usually normal.
New research like the Hunt Study confirms that Broda Barnes was right all along, creating a paradigm shift in thyroid treatment, and constituting a frontal assault on the Institution of Medicine’s thyroid dogma.
TSH is short for thyroid stimulating hormone, made by the pituitary gland. TSH actually stimulates the thyroid gland to make more thyroid hormone, and can therefore be used as a barometer of thyroid function. If thyroid function is low, the pituitary sends out more TSH to stimulate the thyroid to make more thyroid hormone. Above Image: Hunting Dog Courtesy of Wikimedia Commons.
Mainstream Medicine regards the TSH as the single most important test for determining thyroid function. High TSH means low thyroid function, and a Low TSH means normal or high thyroid function.
What Did The Hunt Study Find?
The Hunt Study from the April 2008 Archives of Internal Medicine examined mortality from coronary heart disease (CHD) and TSH level. The authors conclude,
“The results indicate that relatively low but clinically normal thyroid function may increase the risk of fatal CHD.”

The Hunt Study measured thyroid function with the TSH test in 17,000 women and 8,000 men with no known thyroid disease or heart disease. All patients had “normal TSH” levels meaning the TSH values were in the lab reference range of 0.5 to 3.5. The women were stratified into three groups, lower TSH, intermediate and upper TSH levels, and mortality from heart disease was recorded over an 8 year observation period.
(see chart below).
The Hunt study found that group with the higher TSH had a 70% increased mortality from heart disease compared to the lower TSH group. Remember all these TSH vales were in the normal lab range. See chart below for results of the Hunt Study:

| TSH | Death from Heart Disease | |
| Group 1 | 0.50-1.4 | baseline risk |
| Group 2 | 1.5-2.4 | 40% higher than baseline |
| Group 3 | 2.5-3.5 | 70% higher than baseline |
This Finding is Earthshaking !!
This means that merely by taking natural thyroid pills to reduce TSH to the low end of “normal” (0.5), one can reduce death from cardiovascular disease by 70 percent. This mortality benefit is mind boggling and far exceeds any drug intervention available.
Another report from the Hunt Study published in 2007 showed that LDL cholesterol was linearly associated with TSH level. (see chart below).
The Conclusion is Clear:
The best way to normalize lipoprotein profile and reduce mortality from heart disease is to reduce TSH to the lower end of the normal range with thyroid medication. A TSH in the upper end of the normal range is associated with increased cardiovascular mortality and elevations in LDL lipo-protein measurements. A TSH at the lower end of the normal range is associated with protection from heart disease.<
My previous article discussed the issue of statin drugs for women. Decades of published statin drug studies show that statin drugs simply don’t work for women, and don’t reduce mortality from heart disease in women. But on the other hand, the HUNT study shows that TSH levels in the lower normal range provide a 70% reduction in heart disease mortality for women. This can be accomplished safely with inexpensive thyroid medication under a physician’s supervision. So for women concerned about preventing heart disease, this is good news, pointing out a natural alternative to statin drugs that works much better.
Rather than Synthroid, we prefer to use natural thyroid which is a dessicated porcine thyroid gland from RLC Labs. The reason for this is that we have seen better clinical results with the natural thyroid preparations compared to synthroid.

Although natural thyroid is safe, there is always the possibility of adverse effects from thyroid excess, defined as too much thyroid medication. The first sign of thyroid excess is usually a rapid heart rate at rest or perhaps palpitations (at rest). We spend about five minutes at the office going over this adverse effect before starting patients on thyroid medication. Usually patients will notice the heart rate going up or the heart beat sounding louder than usual as the first sign that can be easily recognized. Once recognized, the patient is instructed to stop the thyroid medication, and symptoms usually resolve within 6 hours (for natural thyroid). It is perfectly safe to stop the thyroid medication at any time, as there will be no acute changes, merely a gradual reversion to the original state that existed before starting the thyroid pills.
Some patients are very sensitive to thyroid medication and will have thyroid excess symptoms such as rapid heart rate and palpitations from small amounts of thyroid medication. These are usually the elderly with underlying heart disease and/or magnesium deficiency, and we usually avoid giving thyroid medication to these patients. We also liberally supplement everyone with magnesium if their RBC magnesium levels are low.
About 5 per cent of our patients initially started on thyroid will notice symptoms of thyroid excess with a rapid heart rate, and they will stop the medication for a day or two and restart at a lower dosage with no problem. This is more common in Hashimoto’s patients whose own production of thyroid hormones may fluctuate from month to month. Patients with magnesium deficiency or adrenal fatigue with low cortisol output on salivary testing will also tend to be more sensitive to small amounts of thyroid medication, so caution is advised in these groups as well.
Thyroid Excess Can Rarely Cause Atrial Fibrillation
So far, we have not had a patient go into atrial fibrillation from thyroid medication, probably because we spend so much time with each patient discussing the symptoms of thyroid excess, and the importance of stopping the thyroid medication if these symptoms are noted.
One of the reasons the mainstream conventional docs will give only a minuscule amount of synthroid to the low thyroid patient is that they simply don’t have the time to discuss thyroid excess and can’t afford an adverse event which is more likely if the patient doesn’t have a clue about what to watch out for. In addition, mainstream medical docs don’t recognize the syndrome of adrenal fatigue or magnesium deficiency , so they can run into problems with thyroid excess without understanding why, and this also makes them very cautious, tending to under treat.

In patients with underlying heart disease who are prone to cardiac arrhythmias, thyroid excess can cause atrial fibrillation with characteristic EKG appearance. Atrial fibrillation can be a problem, because if it becomes chronic and doesn’t go away on its own, the cardiologist will try a maneuver called cardioversion, the application of an electrical shock to restart a normal cardiac rhythm. Or, if that doesn’t work, prescribe blood thinners, all of which is not without risk. So it is better to avoid atrial fibrillation altogether by simply stopping the thyroid pills whenever symptoms of rapid heart rate or palpitations are noted while at rest. Exercise induced rapid heart rate, of course, doesn’t count since that is normal cardiovascular response to exercise.
How would I design an even better Hunt Study? That’s easy. Include another group of patients with TSH levels above and below the study group, namely, below 0.5, and above 3.5. I would also include data on annual CAT coronary calcium scores. I would predict that the lower TSH group (below 0.5) would have even less heart disease than the higher TSH group, and that coronary calcium score, indicating plaque burden, would go up as TSH went up.

Background Recent studies suggest that relatively low thyroid function within the clinical reference range is positively associated with risk factors for coronary heart disease (CHD), but the association with CHD mortality is not resolved.
Methods In a Norwegian population-based cohort study, we prospectively studied the association between thyrotropin levels and fatal CHD in 17 311 women and 8002 men without known thyroid or cardiovascular disease or diabetes mellitus at baseline.
Results During median follow-up of 8.3 years, 228 women and 182 men died of CHD. Of these, 192 women and 164 men had thyrotropin levels within the clinical reference range of 0.50 to 3.5 mIU/L. Overall, thyrotropin levels within the reference range were positively associated with CHD mortality (P for trend = .01); the trend was statistically significant in women (P for trend = .005) but not in men. Compared with women in the lower part of the reference range (thyrotropin level, 0.50-1.4 mIU/L), the hazard ratios for coronary death were 1.41 (95% confidence interval [CI], 1.02-1.96) and 1.69 (95% CI, 1.14-2.52) for women in the intermediate (thyrotropin level, 1.5-2.4 mIU/L) and higher (thyrotropin level, 2.5-3.5 mIU/L) categories, respectively.
Conclusions Thyrotropin levels within the reference range were positively and linearly associated with CHD mortality in women. The results indicate that relatively low but clinically normal thyroid function may increase the risk of fatal CHD.

William Davis MD, begin quote:”Is normal TSH too high? There’s no doubt that low thyroid function results in fatigue, weight gain, hair loss, along with rises in LDL cholesterol and other fractions of lipids. It can also result in increasing Lp(a), diabetes, and accelerated heart disease, even heart failure. But how do we distinguish “normal” thryoid function from “low” thyroid function? This has proven a surprisingly knotty question that has generated a great deal of controversy. Thyroid stimulating hormone, or TSH, is now the most commonly used index of the adequacy of thyroid gland function, having replaced a number of older measures. TSH is a pituitary gland hormone that goes up when the pituitary senses insufficient thyroid hormone, and a compensatory increase of thyroid hormone is triggered; if the pituitary senses adequate or excessive thyroid hormone, it is triggered to decrease release of TSH. Thus, TSH participates in a so-called “negative feedback loop:” If the thyroid is active, pituitary TSH is suppressed; if thyroid activity is low, pituitary TSH increases. An active source of debate over the past 10 years has been what a normal TSH level is. In clinical practice, a TSH in the range of 0.4-5.0 mIU/L is considered normal. (Lower TSH is hyperthyroidism, or overactive thyroid; high TSH is hypothyroidism, or underactive thyroid.) The data from a very fascinating and substantial observation called the HUNT Study, however, is likely to change these commonly-held thyroid “rules.” endquote WIlliam Davis MD
