Association of Hemoglobin Drop With 1‐ and 5‐y All‐Cause Mortality After Adjustment in the Multivariable Cox Proportional Hazard Model

	1‐y mortality HR (95% CI)	P value	5‐y mortality HR (95% CI)	P value
No hemoglobin drop	Reference		Reference
Minimal hemoglobin drop (hemoglobin drop <3 g/dL)	2.83 (0.31–26.10)	0.360	6.38 (0.82–49.61)	0.075
Minor hemoglobin drop (hemoglobin drop ≥3 to <5 g/dL)	7.75 (0.77–78.50)	0.083	13.31 (1.64–107.98)	0.016
Major hemoglobin drop (hemoglobin drop ≥5 g/dL)	8.24 (0.71–95.69)	0.090	10.98 (1.23–98.24)	0.035

Age, heart rate (on admission), systolic blood pressure (on admission), creatinine clearance, sex, diabetes, Killip class on admission, previous myocardial infarction, number of diseased vessels, hemoglobin values on admission, and the difference between admission hemoglobin and nadir hemoglobin values were entered into the analysis. HR indicates hazard ratio.
