What is Coronary Heart Disease

What is Coronary Heart Disease? The most common heart disease is coronary heart disease. This disease occurs when the supply of oxygen-rich blood to the heart muscle is inhibited by the plaque in the coronary arteries.


In the artery walls can occur ateroskelosis conditions, namely the accumulation of cholesterol and other substances that increase so narrow the space arteries. This pile is called plaque. Indeed plaque has been lodged in the artery wall since someone was young. The higher the age of a person, the more accumulate plaque in the same location.

The plaque itself secretes a chemical that keeps the inner walls of the vessels sticky. At the same time, blood contains inflammatory cells, lipoproteins, and calcium. These substances will then stick to the walls of blood vessels that make the pile of plaque more and more.

The larger the plaque, the narrower the coronary arteries are so that the oxygen-rich blood supply to the heart is getting thinner. The plaque can also rupture and then clog the bulk up to the entire bloodstream in the arteries. If this blood flow constriction occurs in the coronary arteries, then there can be a heart attack.

In fact, these blood vessels or arteries that constrict this usually make new blood vessels around the narrowed arteries. Unfortunately, new blood vessels may not be able to carry oxygen-rich blood as long as the old blood vessels.


Things That Increase The Chance Of Coronary Heart Disease

The following may increase a person’s risk of atherosclerosis.


What are The Symptoms of Celiac Disease

  1. Cigarettes

Smoking cigarettes are the most important risk for increased risk of coronary heart disease. The content of nicotine and carbon monoxide in cigarette smoke makes the heart work faster than usual. Both substances also increase the risk of blood clots in the arteries. Unfortunately, other chemicals in cigarettes can also damage the coronary artery layer so increasing the risk of coronary heart disease. Smokers are predicted to have a 24% greater risk of coronary heart disease than nonsmokers.

  1. Cholesterol

Cholesterol that flows too much into the blood can cause coronary heart disease. The type of cholesterol that makes the risk of coronary hearts getting bigger is the low-density lipoprotein (LDL) commonly referred to as ‘bad’ cholesterol. Because cholesterol is what has a tendency to stick and hoard in the coronary arteries.

  1. Diabetes

Diabetics are also predicted to have twice the risk of coronary heart disease. This is because diabetics may have a thicker layer of blood vessels than healthy people. Excess thickness in the coronary arteries can lead to an insufficient flow of blood.

  1. The occurrence of blood clots

Blood clots or thrombosis that occur in the coronary arteries will block the blood supply to the heart. Blood clots in the coronary arteries usually occur in the same location as atherosclerosis. Because blood clots block the blood supply to oxygen, it in itself increases the risk of coronary heart disease for those who experience it.

  1. High blood pressure

Blood pressure is too high can also enlarge a person suffering from coronary heart disease. A person is categorized as having high blood pressure if it has systolic pressure in the range of 140mmHg or more, or a diastolic pressure of about 90mmHg or more.


What is a Heart Murmur

Systolic pressure alone is defined as a measure of blood pressure when the heart contracts or pumps blood out. Meanwhile, diastolic pressure is the blood pressure when the heart is relaxed and filling the blood.

To minimize the risk of coronary heart disease, one should be willing to do regular exercise, healthy diet, and quit smoking. Some things like losing weight, lowering blood pressure, and coping with stress can also help prevent the occurrence of coronary heart disease.
