The nurse educator is providing patient education about the Cardiac Arrhythmia Suppression Trial (CAST). The nurse correctly explains that the trial demonstrated that pharmacologic suppression of dysrhythmias
a. reduced mortality by 50% but increased morbidity.
b. significantly reduced the risk of a second myocardial infarction.
c. doubled the risk of a second myocardial infarction.
d. should be used in all patients who have had an MI regardless of rhythm.
ANS: C
In the CAST, class IC dysrhythmic drugs were used to prevent dysrhythmias after MI. These drugs were found to actually double the rate of mortality.
The antidysrhythmic drugs did not reduce mortality or the risk of a second MI. They should not be used for any MI patients with associated dysrhythmias unless the dysrhythmias are life-threatening.
