Serum cTnI Concentrations of Each Group

Group	n	cTnI (ng/mL)
Sham	6	1.32±0.95
CME	6	26.74±4.90*
Low	6	9.87±2.94*#a
High	6	4.45±1.20*#

Notes: Alprostadil injection ameliorated myocardial injury following CME. The results are presented as the mean±standard deviation (SD) of at least three independent experiments. *P<0.05, compared with Sham group, ^#P<0.05, compared with CME group, ^aP<0.05, compared with High group.

Abbreviations: CME, coronary microembolization; Low, CME plus alprostadil injection (2 μg/kg); High, CME plus alprostadil injection (4 μg/kg); cTnI, c-troponin I.
