Effect of Luhong formula on the cardiac rehabilitation of patients with chronic heart failure

Figure 1 Comparative analysis of anaerobic threshold and peak exercise before and after intervention. A: Oxygen consumption at the anaerobic threshold (VO₂ AT) before and after intervention; B: Oxygen consumption at peak exercise (peak VO₂) before and after intervention. ^aP < 0.05 vs before intervention. ^bP < 0.01 vs before intervention. ^cP < 0.05 vs control group. VO₂ AT: Oxygen consumption at the anaerobic threshold; Peak VO₂: Oxygen consumption at peak exercise.

Figure 2 Comparative analysis of left atrial volume index, left ventricular muscle mass index, and left ventricular ejection fraction before and after intervention. A: Left atrial volume index before and after intervention; B: Left ventricular muscle mass index before and after intervention; C: Left ventricular ejection fraction before and after intervention. ^aP < 0.05 vs before intervention. ^bP < 0.01 vs before intervention. ^cP < 0.05 vs control group. LAVI: Left atrial volume index; LVMI: Left ventricular muscle mass index; LVEF: Left ventricular ejection fraction.
