Objective:
To investigate the change of plasma osteopontin level during the progress of acute ST-segment elevation myocardial infarction, as well as its association with the left ventricular remodeling and prognosis.
Methods:
In the study, 61 patients with acute ST-segment elevation myocardial infarction were recruited. Blood samples were taken at admission, on the 3rd day and 7th day of admission, while 63 healthy blood donors were employed as normal controls. There plasma osteopontin levels were measured by ELSIA.
Results:
Compared with the normal controls, the plasma osteopontin levels of the patients with acute ST-segment elevation myocardial infarction were significantly higher at admission [(96.51±37.22) μg/L vs. (54.50±28.17) μ g/L, P<0.001], reached the peak value on the 3rd day, and dropped down on the 7th day. The correlation analysis showed that the plasma osteopontin level positively correlated with age and left ventricular end-systolic volume index 3 months after acute myocardial infarction, and negatively correlated with left ventricular ejection fraction 3 months after acute myocardial infarction. The follow-up study found that the plasma osteopontin level did not predict mortality, re-infarction, stroke, revascularization or hospitalization due to heart failure.
Conclusion:
In patients with acute ST-segment elevation myocardial infarction, the elevated plasma level of osteopontin might be associated with the left ventricular remodeling.
