ΔLVEF (left ventricular ejection fraction), ΔLVEDV (left ventricular end diastolic volume), and ΔLVESV (left ventricular end systolic volume) are calculated as the percentage difference between followup and baseline left ventricular ejection fraction and volumes, respectively. Comparisons were made using the Student’s 𝑡 -test for unpaired data. 𝑃 < . 0 5 ; 𝑃 < . 0 1 .
