Coronary heart disease, or coronary artery disease, is a condition which results when the arteries and veins that are responsible for carrying blood from and to the different parts of the body gets clogged due to accumulation of fat, cholesterol and calcium. Build up of plaque in the arteries is also termed as atherosclerosis.
Due to this condition heart becomes deficient of blood that is required for pumping normally. In the event of this deficiency, the heart has to put more pressure to supply blood to the different parts of the body. When heart continuously puts pressure like this, its muscles tends to weaken causing other serious conditions like heart failure.
There are different causes of developing a coronary heart disease. The first cause is related to the genes. Transmission of this disease from parent to child has been considered as the foremost cause of this disease from generation to generation.
Hypertension, or high blood pressure, has been found to be the second leading cause of coronary heart disease. Due to continued raised blood pressure, the blood in the arteries and veins flows forcefully causing pressure on the entire vascular system.
Higher levels of cholesterol are the next leading cause of coronary heart disease. Cholesterol, a wax kind of substance, is found in the body naturally. When too much of cholesterol is built up in the body due to intake of food rich in cholesterol, it starts accumulating within the blood vessels causing obstruction in the blood flow. Smoking, obesity and diabetes are the other causes of coronary heart diseases.
