The video discusses three major heart conditions: coronary heart disease, faulty heart valves, and heart failure. Coronary heart disease is caused by fatty deposits in arteries and can be treated with stents or statins. Faulty heart valves, which can result from heart attacks or aging, may require replacement with biological or mechanical valves. Heart failure, often due to a weak heart, can be addressed with heart transplants, though these come with risks and long recovery times. Artificial hearts serve as temporary solutions while awaiting transplants.

What is one of the primary causes of coronary heart disease?

• High blood pressure

• Fatty material buildup in arteries

• Excessive exercise

• Low cholesterol levels

How does a stent help in treating coronary heart disease?

• It dissolves fatty deposits

• It narrows the artery

• It keeps the artery open

• It increases blood pressure

What is a potential cause of faulty heart valves?

• Excessive exercise

• Heart attacks

• Low blood pressure

• High cholesterol

What is a disadvantage of heart transplants?

• Immediate recovery

• Unlimited donor availability

• No risk of infection

• Long waiting lists

What is the purpose of an artificial heart?

• To permanently replace the heart

• To temporarily support the heart

• To increase heart rate

• To decrease blood pressure
