A significant inverse correlation was detected in G-CSF patients between the number of circulating CD34 cells at 30 days after reperfusion and the 3-year absolute and indexed LVEDV ( = -0.71 , 95 % CI -0.90 to -0.30 , and = -0.62 , -0.86 to -0.14 , respectively ) , or their change over time ( r = -0.59 , -0.85 to -0.11 , and r = -0.55 , -0.83 to -0.06 , respectively ) .
