To observe the change of urine level of cardiac specific microRNA-1 (miR-1) in patients with ST segment elevation acute myocardial infarction (STEAMI) and investigate its potential applications.Urine samples were collected from 20 STEAMI patients within 12 hours after STEAMI and from 20 healthy volunteers as control. Urine miR-1 concentrations were measured with real-time quantity reverse transcription-polymerase chain reaction (qRT-PCR), at the same time serum cardiac troponin I (cTnI) and MB isoenzyme of creatine kinase (CK-MB) concentrations were measured.Serum level of cTnI, CK-MB and urine level of miR-1 in STEAMI patients were obviously higher than those in healthy control group [cTnI in blood: 19.27±7.53 μg/L vs. 0.02±0.01 μg/L, CK-MB in blood: 93.82±12.30 μg/L vs. 0.86±0.63 μg/L, miR-1 in urine (Ct value): 45.50±4.21 vs. 52.63±4.41, P0.05 or P0.01]. The urine miR-1 level in patients with STEAMI had a strong correlation with serum CK-MB or cTnI when CK-MB300 μg/L and cTnI50 μg/L (Ct value of urine miR-1 with blood CK-MB: r=-0.81, P0.01; Ct value of urine miR-1 with blood cTnI: r=-0.63, P0.05).The results suggest that urine miR-1 could be a novel sensitive biomarker the early diagnosis of SETAMI. |
