*** WHAT'S COVERED ***
1. Introduction to Cardiovascular Disease (CVD)
* Definition as diseases of the heart and blood vessels.
* Examples including coronary heart disease, heart attacks, faulty valves, and heart failure.
2. Coronary Heart Disease (CHD)
* Explanation of how coronary arteries get blocked by fatty material.
* Consequence of reduced blood flow and oxygen to the heart muscle.
3. Treatments for CHD
* Stents: How they hold arteries open, their benefits (quick surgery, long-lasting) and drawbacks (surgical risks, thrombosis).
* Statins: How they alter cholesterol balance (LDL vs HDL), their benefits (lowering disease risk) and drawbacks (regular intake, side effects).
4. Faulty Heart Valves
* Causes of damage or weakening (age, heart attacks, infections).
* How faulty valves affect blood flow (not opening/closing properly).
* Treatment options: Biological vs. mechanical replacement valves, surgical requirements, and risks.
5. Heart Failure
* Definition: When the heart cannot pump blood effectively.
* Overview of treatments including medication and heart transplants.
6. Heart Transplants
* Use of biological (donor) hearts vs. artificial hearts.
* Challenges: Donor availability, immune system rejection, limitations of artificial hearts.
* Mention of heart-lung transplants.
