Sheldon Zerden  uncovers old research linking hypothyroidism to heart disease. Since he makes a correct observation that the medical system in place today only treats the symptoms rather than the disease when it comes to heart disease, and that the cholesterol myth and statin drugs are much more profitable, and since there is definitely a correlation in modern society with thyroid problems and heart disease, I think the old research he references and his hypothesis bears further consideration!
For more information on hypothyroidism, read our article on Coconutdiet.com  regarding how many people with hypothyroidism are getting good results from eliminating transfats and polyunsaturated fats from their diet, and all soy, and consuming coconut oil which boosts metabolism .
Excerpt from Sheldon Zerden’s article :
The cholesterol myth and the trillion-dollar industry that has developed to treat cardiovascular disease is a formidable obstacle to overcome for those who would rather prevent heart attacks than treat the symptoms with bypass surgery, angioplasty, stenting, and cholesterol-lowering drugs.
In 1790, Empress Maria Theresa of Austria mandated autopsies for everyone who died in a hospital. This was a virtual laboratory for medical researchers. In 1890, it was discovered that when a thyroidectomy (removal of the thyroid gland) was performed, the result was a condition called myxedema, in which a jelly-like mucin substance filled the arteries.
This blockage was enough to cause a heart attack and subsequent death. However, in those days, the major cause of death was tuberculosis. Heart disease was infrequent, so a cure for heart disease was not sought.
Today, it’s a different story. Heart attacks and all the treatments for this problem are fighting a losing battle. When you treat the symptoms of a disease, you don’t get to the root cause of the problem.
Sometimes the solution to a problem is so simple that we can’t believe it. We therefore overlook it.
