AB  - OBJECTIVE: Correlation between myocardial infarction (MI) scar by cardiac 
      magnetic resonance and the Lown's classification of ventricular premature beats 
      (VPBs) is poorly understood. This study aims to investigate the correlation 
      between the MI scar characteristics by delayed-enhancement magnetic resonance 
      imaging (DE-MRI) and the Lown's classification of VPBs. METHODS: Sixty-five 
      patients, in the convalescence stage and consolidation phase of MI, were included 
      in this retrospective study. All patient were divided into VPBs group (n = 39) 
      and non-VPBs group (n = 26 patients) according to the clinical diagnostic 
      criteria of Universal Definition of MI scar. VPBs patients were assigned to 
      Lown's I-II group and Lown's III-IV subgroup in accordance with the Lown 
      classification criteria. Cardiac function parameters and MI scar characteristics 
      were detected by cardiac magnetic resonance (CMR) and DE-MRI, respectively. 
      RESULTS: Lown's classification was negatively correlated with left ventricular 
      ejection fraction (LVEF), peak ejection rate (PER) and peak filling rate (PFR) 
      (-0.724, -0.628, -0.559), and positively correlated with MI area, MI integral, MI 
      segments number and left ventricular end systolic volume (LVESV) (0.673, 0.655, 
      0.586, and 0.514), respectively.CONCLUSIONSThe study indicated that MI area and 
      MI integral were strongly associated with Lown's classification.
