Non-HF = nonheart failure; HF = heart failure; Non-DP = nondilated phase; DP = dilated phase; UPes = tetrofosmin uptake at end-systole; RW = regional % washout of MIBG; MUPe = early MIBG uptake; MUPd = delayed MIBG uptake.
Data are presented as mean ± SD. Values in parentheses are number of myocardial segments.
