Association of Hemoglobin Concentration and Its Change With Cardiovascular and All-Cause Mortality.

ABSTRACT: Anemia is thought to increase mortality risks, but the effects of high hemoglobin concentration on survival are unclear. The effect of change in hemoglobin concentrations on survival in the general population is also unknown. This study aimed to examine the effect of hemoglobin concentrations and their changes on cardiovascular and all-cause mortality risks. We retrospectively analyzed a cohort from the NHIS-HEALS (National Health Insurance Service-National Health Screening Cohort) database, including 170 078 men and 122 116 women without cardiovascular diseases, aged >40 years at baseline, with hemoglobin concentrations available for both first and second health examinations. We assessed 2 independent variables: "One-time" hemoglobin concentrations and changes in hemoglobin from first to
