Table 4. Relationship Between Drug Usage and Composite MACEs After 2-Year Follow-Up.

LVEF < 50% (n = 87)
LVEF ≥ 50% (n = 391)
MACEs (n = 41) Without MACEs (n = 46) MACEs (n = 131) Without MACEs (n = 260)
Any one drug treatment 0 2 2 4
Any two drugs treatment 9 8 27 31
Any three drugs treatment 15 18 58 113
All four drugs treatment 17 18 44 111
P value Z = -0.228, P = 0.820 Z = -2.167, P = 0.03

LVEF: left ventricular ejection fraction; MACEs: major adverse cardiac events.
