Understanding Diastolic Heart Failure

What is the primary difference between diastolic and systolic heart failure?

• Systolic heart failure involves the heart not pumping enough blood.

• Diastolic heart failure involves the heart not filling with enough blood.

• Diastolic heart failure involves the heart pumping too much blood.

• Systolic heart failure involves the heart filling with too much blood.

In diastolic heart failure, what happens to the ejection fraction?

• It is always lower than normal.

• It is unaffected by heart failure.

• It can be preserved despite lower stroke volume.

• It is always higher than normal.

What role does fibrotic tissue play in diastolic heart failure?

• It decreases the heart's compliance.

• It increases the heart's compliance.

• It makes the heart more flexible.

• It has no effect on the heart's compliance.

How does chronic hypertension contribute to diastolic heart failure?

• By reducing the heart's muscle mass.

• By decreasing blood pressure.

• By making blood vessels more elastic.

• By causing the heart to bulk up.

What is aortic stenosis and how does it affect the heart?

• It is a condition that decreases blood pressure.

• It is a condition that increases blood flow.

• It is a narrowed valve that makes pumping harder.

• It is a widened valve that makes pumping easier.

Which cardiomyopathy is characterized by muscle growth without an obvious cause?

• Restrictive cardiomyopathy

• Dilated cardiomyopathy

• Hypertrophic cardiomyopathy

• Ischemic cardiomyopathy

What is the effect of restrictive cardiomyopathy on the heart?

• It decreases the heart's muscle mass.

• It increases the heart's ability to expand.

• It causes the heart muscles to become stiffer.

• It causes the heart muscles to become more flexible.

Which of the following is a risk factor for diastolic heart failure?

• Low blood pressure

• Coronary artery disease

• Increased heart rate

• Decreased muscle mass

How does the cycle of worsening heart failure progress?

• By decreasing muscle size and flexibility.

• By reducing blood pressure and heart rate.

• By increasing muscle size and oxygen demand.

• By increasing oxygen supply to the heart.

What happens to the heart muscles in diastolic heart failure?

• They become more elastic.

• They become larger and stiffer.

• They become smaller and more flexible.

• They remain unchanged.
