It's very important to understand what causes heart disease because that's the only way to prevent the problem from developing or, if we already suffer from it, to treat it.
straight to the foods that can help prevent and treat it, then go to
Healing Foods for Heart Disease, otherwise, read on to expand your knowledge of this condition.
I'm sure you're aware that cardiovascular disease, or just known as heart disease, is the most common cause of death in the UK, USA and most of the industrialized countries.
But what causes heart disease and, above all, what can we do to prevent it or even reverse it?
Does what we eat affect the health of our heart?
When you are born, your arteries are clean, open and elastic.
Then something happens that causes damage to your blood vessel walls, which exposes the underlying connective tissue and the collagen.
That damage could be caused by many factors:
When the platelets in the blood come into contact with the collagen that has been exposed, they trigger a natural repair mechanism that starts to form clots.
The immune cells that rush in to repair the damage do so as part of an inflammatory process that actually damages blood vessels further, thickens the blood and contributes to the formation of blood clots.
This process causes a proliferation of endothelial cells lining the arteries, and fatty streaks appear. These are formed by oxidized cholesterol, immune cell debris and calcium salts and this deposit gradually thickens the walls of the arteries.
Gradually these streaks are transformed into plaque, or atheroma - fatty scar tissue, which narrows the artery and reduces elasticity, eventually reducing blood flow through the vessel.
This process is known as atherosclerosis and is what causes heart disease to develop.
If the clot, or thrombus, becomes large enough, it can block off blood flow, suffocating large patches of cardiac muscle, causing what we know as heart attack, or myocardial infarction (MI).
The severity of the heart attack depends on how reduced the blood flow is.
In acute myocardial infarction, the supply of oxygen is so severely reduced that the region of the heart muscle may die (necrosis) within an hour or so and, as a result, the activity of the whole heart may be severely threatened.
Pains in the chest that come on during exercise, over-eating and stress are early warning signs that the blood supply to the arteries of the heart is restricted, and are known as angina pectoris.
The clot or thrombus may also sometimes break away from its anchor point and form a mobile embolus (thromboembolism).
A freely moving embolus may partially or completely plug a smaller vessel as it flows downstream and can result in a gradual or sudden blockage of any blood vessel.
So what causes heart disease is also the cause of other serious cardiovascular problems.
Symptoms may vary from mild to strong and do not all occur in every heart attack. But if any combination of these takes place, get help fast!
However, in some cases there are no symptoms; these are referred to as silent heart attacks.
So far we've talked about the mechanics of heart disease but we haven't mentioned what the risk factors are or what part food plays in it. Please look at Part 2 of this series: Reverse Heart Disease with Healing Foods
