Data are presented as mean ± SD or absolute value (percentage) of occurrence. RMI, recent myocardial infarction group; LMI, late myocardial infarction group; CAD, stable coronary artery disease group; n, number of individuals; MI, myocardial infarction; LVEF, left ventricular ejection fraction; Pre, pretreatment; Post, posttreatment. Significant difference in relation to CAD. ⁺Significant difference in relation to RMI. ^#Significant difference in relation to pretreatment (). The chi-square test and Fisher’s exact test were used.
