In the patient population with reduced left ventricular ejection fraction (LVEF ≤ 45%), 10.0% of the ASV group experienced a cardiovascular death each year compared to 7.5% of the control group, representing a 33.5% relative increased risk of cardiovascular mortality (HR=1.335, 95%CI=(1.070, 1.666), p‐value= 0.010).
