Question 18 in “Clinical Quiz” (September 15, 2001, page 921), pertaining to the article “Guideline for the Management of Heart Failure Caused by Systolic Dysfunction: Part II. Treatment,” was inaccurately worded. Answer choice C should refer to exercise-induced asthma rather than severe exercise-induced asthma—mild asthma is not a contraindication to the use of beta blockers in patients with systolic heart failure. The corrected question is printed below; the correct answers are A and C.
Q18. Beta blockers should not be used in patients with systolic heart failure and which of the following conditions?
A. Hemodynamic instability.
B. Dyspnea at rest.
C. Exercise-induced asthma.
D. History of myocardial infarction.
