Cardiovascular Disease and Treatments

The video provides an overview of cardiovascular diseases, focusing on coronary heart disease, heart valve issues, and heart failure. It discusses treatments like stents, statins, valve replacements, and heart transplants. The video highlights the benefits and risks of each treatment, including the challenges of finding donor hearts and the potential for organ rejection.

What does cardiovascular disease generally refer to?

• Diseases of the respiratory system

• Diseases of the cardiovascular system

• Diseases of the digestive system

• Diseases of the nervous system

What is the primary cause of coronary heart disease?

• Buildup of layers of fatty material in the coronary arteries

• Infection in the heart muscle

• Genetic mutations

• Lack of exercise

What is a stent used for in the treatment of coronary heart disease?

• To replace the heart

• To reduce cholesterol levels

• To hold open the arteries

• To replace a faulty heart valve

What is the main function of statins?

• To prevent infections

• To increase blood flow

• To replace damaged heart valves

• To decrease bad cholesterol and increase good cholesterol

What are the two types of cholesterol mentioned in the video?

• LDL and IDL

• HDL and VLDL

• VLDL and IDL

• HDL and LDL

What can cause heart valves to become damaged or weakened?

• High blood pressure

• Lack of exercise

• Poor diet

• Old age, heart attacks, and infections

What are the two main types of replacement valves?

• Biological and mechanical valves

• Plastic and metal valves

• Temporary and permanent valves

• Synthetic and organic valves

What is the only proper treatment for heart failure?

• Medications

• Exercise

• A new heart

• Diet changes

Why are artificial hearts generally only a temporary fix?

• They are not as effective as real hearts

• They are too expensive

• They are difficult to implant

• They cause severe side effects

What is one advantage of artificial hearts over donor hearts?

• They last longer

• They are made of metals and plastic, so the immune system doesn't reject them

• They are cheaper

• They are easier to implant
