Table 4 Model for LVEF measured by cardiac catheterization (reference echocardiogram) and not early (reference Early) (N = 445, no of events = 52)

From: In-hospital measurement of left ventricular ejection fraction and one-year outcomes in acute coronary syndromes: results from the IMMEDIATE Trial

Variable HR (95 % CI) P value
LVEF/5 % lower (combined) 1.25 (1.14, 1.37) < 0.001
 Age/10 years Increase 1.71 (1.36, 2.15) < 0.001
 History of CAD (MI, PCI, or CABG) 2.94 (1.60, 5.40) < 0.001
 LVEF - echocardiogram (reference catheterization) 1.62 (0.93, 2.80) 0.08
LVEF/5 % lower (combined) 1.25 (1.13, 1.36) < 0.001
