A total of 826 patients who had been hospitalized for HF and were being treated for insomnia with either benzodiazepines or Z\u2010drugs (zolpidem, zopiclone, or eszopiclone), were enrolled and divided on the basis of their hypnotics: benzodiazepine group (n=488 [59.1%]) and Z group (n=338 [40.9%]). We compared the patient characteristics and postdischarge prognosis between the groups. The primary end points were rehospitalization for\n              <jats:styled-content style=\"fixed-case\">HF<\/jats:styled-content>\n              and cardiac death.
