Cardiovascular disease

• Stents keep arteries open
• Coronary heart disease is when the coronary arteries become blocked by fatty deposits causing the arteries to narrow and restrict blood flow
• Stents are tubes that are inserted inside arteries to keep them open.
• Stents lower the risk of heart attack and are effective for a long time, the recovery time from surgery is relatively quick
• There is a risk of patients developing a blood clot called a thrombosis near the stent
• Statins reduce cholesterol in the blood
• Cholesterol is an essential lipid that your body produces and needs to function properly. However there is also bad cholesterol which can cause coronary heart disease.
• Statins reduce the amount of bad cholesterol in the bloodstream and slows down the rate of fatty deposits forming.
• Statins are a longterm drug that must be taken regularly there's the risk that someone could forget to take them
• Statins can sometimes cause negative side effects such as headaches or even memory loss
• Statins effect isn't instant
• Artificial hearts are mechanical devices that pump blood for those with heart failure but they are usually only used as a temporary fix until a donor heart is found.
• Artificial hearts are less likely to be rejected by the body's immune system than a donor heart
• Blood doesn't flow through artificial hearts as smoothly which can cause blood clots and lead to strokes
• Statins can also increase the amount of beneficial cholesterol
• Faulty heart valves can be replaced with a mechanical valve or a biological valve
• Valves in the heart can be damaged by

  • Heart attacks
  • Infection
  • Old age
• A valve may become leaky allowing blood to flow in both directions rather than just forward
• Biological valves can be taken from humans or other mammals
• Artificial blood can keep you alive in an emergency. It’s generally a saline solution
