Circulating miR-1254 predicts ventricular remodeling in patients with ST-Segment-Elevation Myocardial Infarction: A cardiovascular magnetic resonance study

Sci Rep. 2018 Oct 11;8(1):15115. doi: 10.1038/s41598-018-33491-y.

Abstract

Reliable noninvasive prognostic biomarkers for left ventricular (LV) remodeling in ST-segment elevation myocardial infarction (STEMI) are needed. This study aimed to evaluate a panel of circulating microRNAs (miRNAs) as biomarkers of LV remodeling using cardiovascular magnetic resonance (CMR). We prospectively evaluated patients with a first STEMI treated with primary percutaneous coronary intervention who underwent CMR imaging at 1 week and 6 months after STEMI (n = 70). miRNAs were measured using PCR-based technologies in plasma samples collected at admission. The associations between miRNAs and LV diastolic and systolic volumes, and ejection fraction at 6-months were estimated in adjusted models. Median age was 60 years, 71.4% were male. miR-1254 was significantly associated in univariate analyses. Patients in the highest tertile of miR-1254 exhibited lower values of LVEDVI and LVESVI and higher values of LVEF at 1 week. After comprehensive multivariate adjustment including clinical, CMR variables, hs-troponin-T and NT-proBNP, miRNA-1254 was associated with decreasing LVESVI (P = 0.006), and borderline negative associated with LVEDVI (P = 0.063) at 6-months. miR-1254 also exhibited a significant positive association with increasing LVEF during follow-up (P < 0.001). Plasma miRNA-1254 predicted changes in LV volumes and LVEF at 6 months after STEMI. The value of miR-1254 to inform tailored treatment selection and monitor ongoing efficacy deserves further investigation.
