Patient Characteristics
The baseline characteristics of the 1,178 patients with 3 or more EF
measurements, who were included in this analysis, are shown in Tables 1
and 2. Compared to those without EF recovery, those with improvement in
EF were more likely to be female, have non-ischemic cardiomyopathy, a
QRS duration < 120 ms and a more recent heart failure
diagnosis (Tables 1 and 2).
