| Risk Factors | Smoking;High Blood Pressure; Blood Cholesterol (LDL); High salt levels; High levels of saturated fats. |
| Thrombosis (description) | A thrombosis is a blood clot within an artery (or a vein). If a thrombosis occurs in a coronary artery (coronary thrombosis), it will cause the artery to narrow, preventing the blood supply from reaching the heart muscle. This increases your chance of having a heart attack. Coronary thrombosis usually happens at the same place that the atherosclerosis is forming (furring of the coronary arteries). |
| Cholesterol (LDL and HDL) | Cholesterol is a fat made by the liver from the saturated fat that we eat. Cholesterol is essential for healthy cells, but if there is too much in the blood it can lead to CHD. Cholesterol is carried in the blood stream by molecules called lipoproteins. There are several different types of lipoproteins, but two of the main ones are low-density lipoproteins (LDL) and high-density lipoproteins (HDL). LDL, often referred to as bad cholesterol, takes cholesterol from the liver and delivers it to cells. LDL cholesterol tends to build up on the walls of the coronary arteries, increasing your risk of heart disease. HDL, often referred to as "good cholesterol", carries cholesterol away from the cells and back to the liver, where it is broken down or passed from the body as a waste product. |
| Carbon Monoxide | CO combines with haemoglobin to form carboxyhaemoglobin which reduces the oxygen carrying capacity of the blood. This raises blood pressure as the heart has to work harder to supply cells with the same amount of oxygen. |
