The 20 questions
-
What material builds up inside coronary arteries during coronary heart disease?
- Muscle tissue
- Fatty material
- Blood clots
- Calcium carbonate
-
What is the direct consequence of narrowed coronary arteries on the heart?
- Increased blood pressure
- Thicker ventricle walls
- Reduced oxygen supply
- Faster heart rate
-
What is the primary function of medical stents in coronary heart disease?
- Removing fatty deposits
- Keeping arteries open
- Replacing heart valves
- Lowering blood pressure
-
What is the main role of statins in treating cardiovascular disease?
- Thinning the blood
- Increasing heart rate
- Dilating blood vessels
- Lowering blood cholesterol
-
What is a common fault that can occur in human heart valves?
- Pumping extra oxygen

- Reversed heart failure
- Immediate valve repair
- Slower fatty deposits
-
Which treatment mechanically keeps an artery open?
- A biological valve

- A stent
- A statin
-
Why must heart disease treatments like transplants be carefully evaluated?
- Patient age restrictions
- High financial cost
- Benefits versus risks
- Surgery duration limits
-
Why does coronary heart disease result in a lack of oxygen for the heart?
- Blocked lung capillaries
- Damaged lung tissue
- Increased breathing rate
- Reduced blood flow
-
Which temporary device keeps a patient alive while awaiting a heart transplant?
- Cardiac pacemakers
- Coronary stent
- Artificial heart
- Mechanical valve
-
What is the immediate mechanical consequence of a leaking heart valve?
- Valves fuse shut
- Heart rate triples
- Blood flows backwards
- Arteries widen
-
What happens to the heart muscle if coronary blood flow drops significantly?
- Blood pressure rises
- Starved of oxygen
- Cell division stops
- Muscle mass increases
-
What is the primary medical purpose of a heart stent?
- Lower blood cholesterol
- Keep arteries open
- Replace faulty valves
- Remove fatty deposits
-
A doctor chooses between a drug, a device or a transplant. Which is the most invasive option?
- Statin tablets
- Dietary advice
- Taking a medication
- Transplant
-
Why is coronary heart disease classified as a non-communicable disease?
- Passed on via air
- Infectious between people
- Not caused by pathogens
- Spread through coughing
-
What is the limiting factor for performing a heart transplant procedure?
- Available donor heart
- Surgical cost limits
- Hospital operating room
- Patient blood group
-
What is the primary function of a stent?
- Holds artery open
- Lowers blood cholesterol
- Kills pathogens
- Increases heart rate
