Stents & Statins
- Stents are used to keep coronary arteries open.
- Fatty material can accumulate and narrow arteries.
- A stent is a wire mesh inserted to expand the artery's lumen and improve blood flow.
- Stent insertion is a simple procedure where the patient can remain awake.
- The stent is inserted through a small cut into a blood vessel in the arm or leg.
- Advantages of stents include improved blood flow to the heart muscle.
- Disadvantages include the potential need for additional stents if more fatty material builds up.
- Lifestyle changes are necessary to prevent further buildup, as stents do not address the underlying cause.
- Multiple operations to fit extra stents can be a disadvantage.
- Statins are drugs that help reduce cholesterol levels in the blood and are taken once a day.
- Statins slow the rate of fat buildup in the arteries.
- Advantages of statins include being cost-effective, reducing the risk of further heart disease, and decreasing bad cholesterol.
- Disadvantages of statins include the need for long-term use, potential side effects like headaches, and unsuitability for people with liver disease or those who are breastfeeding or pregnant.
