I beg the indulgence of my readers. This information may be a little dull and boring but it shows the insidious nature of this disease that is so subtle, many times, in its approach, but so often deadly in its results. As I said in the beginning, much of the time, the first sign that you have heart disease is . . . . sudden death!
This picture shows a lengthwise cross section of an artery and actually illustrates the progression of cardiovascular disease. First, you have normal, healthy artery. Then early fatty streaks begin showing up which continue and grow. White and Red blood cells form an internal rupture within the endothelium (the lining of the blood vessels) and inflammation and calcification begin. A calcified shell forms around this lipid-rich plaque and, with scarring, calicified plaque develops. White blood cells accumulate to the point where the artery is vulnerable and there is a possibility of a rupture. This is what happend to Tim Russert. He didn't have much blockage (only about 40%) but it ruptured and, therefore, the first real sign of his problem was his death.
When a Thrombus and Myocardial Infarction occurs, doctors must go in and place a stent, which is a tube designed to be inserted into a vessel or passagway to keep it open. The other option is to put in a new vein or artery to bypass the damage.
How fast this progression occurs is determined by what we eat and what we assimilate!
Here we are comparing three cross-cut sections of arteries: First, a healthy blood vessel, where the endothelium is relaxed and the vessel is open. Second is a narrowed artery where constriction is occuring because of a lack of Nitric Oxide.
Nitric Oxide is what the endothelium produces to keep the arteries relaxed and vasodilated. This problem is compounded by the plaque build-up. But notice the third artery, where Nitric Oxide has been increased allowing for dilation. Even with the plaque still present, one can see how blood flow is increased!
In my next post I will discuss how our bodies produce this essential Nitric Oxide and what we can do nutritionally to enhance its production . . . . and . . . . . put a halt to Cardiovascular Disease Progression!
