Relationship analysis between log2−delta CT of exo-miR-92b-5p and echocardiographic indices. (A) log2−delta CT of exo-miR-92b-5p vs. LAD (Spearman correlation: r=0.480, P<0.001); (B) log2−delta CT of exo-miR-92b-5p vs. LVEF (Spearman correlation: r=–0.457, P<0.001); (C) log2−delta CT of exo-miR-192-5p vs. LVDD (Spearman correlation: r=0.434, P=0.001); (D) log2−delta CT of exo-miR-192-5p vs. LVFS (Spearman correlation: r=–0.502, P<0.001); (E) log2−delta CT of exo-miR-192-5p vs. LVSD (Spearman correlation: r=0.429, P=0.001). LAD, left atrial diameter; LVDD, left ventricular diastolic diameter; LVSD, left ventricular systolic diameter; LVEF, left ventricular ejection fraction; LVFS, left ventricular fraction shortening.
