ways of treating Cardiovascular diseases

• Multicellular organisms require transport systems to supply their cells and remove waste products.
• In humans, one of the functions of the circulatory system is to transport substances.
• Statins are drugs that help to lower cholesterol in the blood.
• Statins are prescribed for people with heart disease or who have a high risk of developing it.
• Statins need to be taken long-term.
• Cholesterol levels will rise again if a person stops taking statins.
• Some studies have raised concerns regarding the side effects of statin use, while others believe they can bring additional positive benefits.
• Statins are not suitable for everyone - they should not be prescribed for people with liver disease, or pregnant or breast feeding women.
• Some patients taking statins often experience side-effects such as headaches and memory loss.
• There have been reports of statins being linked with type 2 diabetes.
• Coronary arteries that are blocked or have become narrow can be stretched open and a stent inserted to restore and maintain blood flow.
• Stents are made from metal alloys and do not lead to an immune response in the patient.
• Around 75 000 operations are carried out each year.
• Risk factors for heart transplants depend on the patient's age, general health, and whether they have had a heart attack.
• The operation is safe as it does not involve surgery, but there is a risk of bleeding, heart attack or stroke.
