Effect of Admission cTnI Levels on Cardiac Function of Patients with Acute Myocardial Infarction Referred to Reperfusion

Objective: To investigate the effect of admission cardiac troponin I (cTnI) levels on cardiac function of patients with ST elevation acute myocardial infarction(STAEMI) to primary percutaneous coronary intervention(PCI).Method: 95 cases with STEAMI who underwent primary PCI were divided into 2 groups,normal cTnI group and elevating cTnI group,according to the admission cTnI levels.During hospitalizion,ultrasonic cardiogram and use of digoxin and duretics were observed.Result: Compared with nomal cTnI group,durations of chest pain before admission were longer and peak CK-MB levels were higher(both P0.05).In elevating cTnI group,left ventricular end-systolic volumes were larger,ejection fractions of left ventricles were lower,the rates of ventricular aneurysm and the rates of use of digoxin and diuretis were higher than those of normal cTnI group.Conclusion: High admission cTnI levels were associated with poor cardiac function in patients with ST elevation acute myocardial infarction(STAEMI) to primary percutaneous coronary intervention(PCI).We should pay more attention to those patients to avoid onset of acute cardiac failure.
