Diastolic dysfunction: dx
Pretest
Question 1
True or False
1. Diastolic heart failure is defined as a condition caused by increased resistance to the filling of one or both ventricles.
2. This leads to symptoms of congestion from the inappropriate upward shift of the diastolic pressure-volume relation.
3. Although this definition describes the principal pathophysiologic mechanism of diastolic heart failure, it is not clinically applicable.
4. A more practical definition for use in clinical practice is: a condition that includes classic CHF findings and abnormal diastolic and normal systolic function at rest.
Question 2
True or False
Heart failure can present as
1. fatigue, dyspnea on exertion,
2. paroxysmal nocturnal dyspnea, orthopnea,
3. jugular venous distention, rales,
4. tachycardia, third or fourth heart sounds,
5. hepatomegaly, and edema.
Question 3
True or False
1. The serum brain natriuretic peptide (BNP) test can accurately differentiate heart failure from noncardiac conditions in a patient with dyspnea.
2. It can distinguish diastolic from systolic heart failure.
3. Physicians also should consider that patients' New York Heart Association severity class affects BNP levels.
4. A study group proposed that physicians combine clinical and echocardiographic information to categorize patients with diastolic heart failure according to the degree of diagnostic certainty.

Answer
TFTT
The serum brain natriuretic peptide (BNP) test can accurately differentiate heart failure from noncardiac conditions in a patient with dyspnea, but it cannot distinguish diastolic from systolic heart failure.
Physicians also should consider that patients' New York Heart Association severity class affects BNP levels.
