Osteopontin is a secreted extracellular-matrix glycoprotein that plays a role in the healing of remodeling tissue. We examined the relationship of plasma osteopontin levels with left-ventricular (LV) volume and function in 18 consecutive patients who underwent successful reperfusion after anterior-wall acute myocardial infarction (AMI). The plasma osteopontin level was within the control range at admission (mean ± SD 420 ± 195 ng/mL), began to increase on day 2 (935 ± 464 ng/mL), and reached a maximum around day 3 (1139 ± 482 ng/mL). The level remained high on days 4, 5, and 7 (∼1000 ng/mL) and then decreased on day 14. Maximal plasma osteopontin levels and the difference between maximal and minimal levels were positively correlated with LV end-systolic volume index (r =. 58, P
