Table 3 The comparison of left ventricular function between AAβ and no-AAβ group

From: Real-world use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/β-blocks in Chinese patients before acute myocardial infarction occurs: patient characteristics and hospital follow-up

  1. AAβ ACEI/ARB/β-B, BMI body mass index, LA left atrium, LVEDD left ventricular end-diastolic dimension, EF left ventricular ejection fraction, FS fraction shortening, E/A ratio of early to late ventricular filling velocities
  2. p values for comparisons between the two groups. Significance level was 0.05
