Understanding Systolic Heart Failure

What is the primary issue in systolic heart failure?

• The heart pumps too much blood.

• The heart cannot pump blood as effectively.

• The heart beats too slowly.

• The heart beats too quickly.

What analogy is used to describe the heart's pumping action in systolic heart failure?

• A car engine running.

• A water bottle being squeezed.

• A sponge soaking up water.

• A balloon being inflated.

What typically causes the weakening of heart muscles in systolic heart failure?

• Death of cardiac muscle cells.

• Increased heart rate.

• Excessive exercise.

• High blood pressure.

What is the term for diseases that affect the heart muscle?

• Arrhythmias

• Atherosclerosis

• Cardiomyopathies

• Hypertension

How does coronary artery disease contribute to systolic heart failure?

• By increasing heart rate.

• By reducing blood supply to the heart muscle.

• By causing the heart to beat irregularly.

• By enlarging the heart chambers.

What happens during regurgitation in valve diseases?

• Blood flows backward into the upper chambers.

• Blood flows too quickly to the body.

• Valves open too widely.

• Valves close too tightly.

What is stenosis in the context of valve diseases?

• Valves that open too widely.

• Valves that do not close properly.

• Narrowing of the valve opening.

• Valves that are too flexible.

What does an arrhythmia refer to?

• A weak heart contraction.

• A normal heart rhythm.

• An abnormal heart rhythm.

• A strong heart contraction.

What does the ejection fraction measure?

• The pressure of blood in the veins.

• The speed of blood flow through the arteries.

• The percentage of blood ejected with each heartbeat.

• The total blood volume in the body.

What ejection fraction percentage indicates heart failure?

• Above 70%

• Between 55% and 70%

• Between 40% and 55%

• Below 40%
