Objective To observe the changes of RDW in patients with coronary heart disease (CHD).
Methods 287 CHD patients diagnosed by coronary angiography were selected from Jun. 2007 to Jun. 2008. Meanwhile, 286 hypertensive patients and 302 healthy adults were enrolled as control group. Red blood cell count (RBC), Haemoglobin (HGB), red blood cell distribution width (RDW-CV) was detected by full automatic haemocyte analyser (Sysmex XE-2100).
Results Compared with hypertension and normal control group, the RDW of CHD group significantly increased. There was no difference between the male RDW in three groups. But the RDW of female CHD subgroup was higher than those of female hypertensive and normal subgroups (13.5±0.8 vs 13.0±0.6 vs 13.1±0.8, p<0.05). Meanwhile, the RDW of female CHD subgroup was higher than that of male CHD subgroup also (13.5±0.8 vs 13.1±0.7, p<0.05).
Conclusion The RDW in CHD group has gender differences and only female RDW significantly increase.
