Extract

To the Editor: Dr Albert and colleagues1 studied the prescription of aldosterone antagonists for patients with heart failure (HF). Among the patients studied, 46% had nonischemic HF. It would be helpful to know whether the strength of the associations with aldosterone antagonist use found in the study differed between the nonischemic group and the ischemic group.

Because the use of aldosterone antagonists together with angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, or β-blockers can lead to hypotensive episodes,2 I would like to know if the authors assessed whether this reaction could explain interruption in aldosterone antagonists use. Also, because new-onset arrhythmia may be influenced by the renin-angiotensin-aldosterone system,3 I would like to know whether the authors assessed correlation between onset of arrhythmia and aldosterone antagonist use.
