Figure 1. Left ventricular ejection fraction (LVEF) at baseline and discharge of patients with ST‐segment–elevation myocardial infarction of March 2019 and March 2020.

Figure 1

Data are expressed as median and interquartile range (IQR). The baseline and discharge median and IQR of LVEF in March 2019 was 42% (IQR, 37%–47%) and 48% (IQR, 42%–55%), respectively. The baseline and discharge median and IQR of LVEF in March 2020 was 35% (IQR, 32.5%–42.5%) and 35% (IQR, 35%–40%), respectively. The median of delta (∆) between baseline and discharge LVEF in patients of 2019 is 5 (IQR, 0–8); and in patients of 2020, 0 (IQR, 0–2.5). The difference was 3 (95% CI, 0–5; P=0.011).
