Causes

Doctors cannot agree on the number one cause of heart disease, so you will have to evaluate the evidence yourself and determine your own risk/reward ratio. Smoking, obesity, and high cholesterol are usually in the forefront of any study.

The chemicals in cigarettes can damage artery walls, thereby making it easier for cholesterol deposits to build blood-blocking deposits on the artery walls. Smoking also makes platelets, the component of blood that causes clotting and carries oxygen, to be more active, thus increasing the risks of blood clots that cause heart attacks and storks.

A body needs cholesterol and can actually produce all it needs, so when we ingest foods high in cholesterols, like dairy and meat products, our bodies get a lot more cholesterol than they need. The body saves cholesterol instead of excreting it, and that cholesterol gets stored along the walls of the arteries. Too many cholesterol deposits lead to artery blockage and clots.

Having a large numbers of large HDL particles correlates with better health and it is commonly called “good cholesterol”. Having a large number of LDL particles in the blood is commonly called “bad cholesterol”. However, as today’s testing methods determine LDL (“bad”) and HDL (“good”) cholesterol separately, this simplistic view has become somewhat outdated.

High blood pressure is also thought to be a major cause of heart disease. Give this a try. Plug you nose and breath through you mouth. No problem right? Now put something about the size of a garden hose in you mount and breath through that. It is harder to get enough oxygen but it is still not unreasonable. Not try breathing through a straw. You will not be able to do this for every long before you have to give up.

Your arteries are narrowed because of all that cholesterol stored on the walls of the arteries. But your body needs the same amount of oxygen that is supplied by the blood that is always has. Your heart has to pump harder and faster to give the body what it needs. As you arteries become narrower and narrower your heat has to work harder and harder. Sooner or later something has got to give.

Obesity is another factor that can cause heart disease. Often obesity comes with high cholesterol and high blood pressure, which can increase the risk of heart disease and stroke. Since there are more areas that need blood because of the increased size of someone suffering from obesity the heart must work harder to supply the needs of the body.

Stress is also associated with heart disease. But unless your parents are stressing you out enough to cause a heart attack, they are not the cause of heart disease.
