Abstract
OBJECTIVE: To investigate the levels of blood fat, C-reactive protein (CRP) and hemorheological indicators in the elder patients with coronary heart disease (CHD), so as to provide evidence for prospective study and treatment of elder CHD. METHODS: We collected the clinical data of 127 elder CHD patients who admitted to this hospital between July 2016 and December 2017 to detect the levels of blood fat, CRP and hemorheological indicators. RESULTS: In elder CHD patients, levels of the total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterin (LDL-C) were significantly higher than the normal reference, and comparison with the control group also showed significant increases (p < 0.01); average levels of the high-density lipoprotein cholesterin (HDL-C), phospholipid (PL), lipoprotein a [LP (a)] and free fatty acid were in the range of normal reference. Abnormal levels of TC, TG, LDL-C and HDL-C were identified in 59.06%, 58.27%, 51.18% and 18.11% of the elder CHD patients, most of which were concomitant with obesity or hypertension, and levels of these indicators were significantly higher than those in the control group with statistically significant differences (p < 0.01). Comparisons of the age, gender distribution, hypotension, exercise and sleep showed that differences had no statistical significance (p > 0.05). In comparison with the control group, the levels of CRP, the whole blood viscosities at high and low shears, plasma viscosity, hematocrit value, aggregation index and rigidity index of red blood cells (RBC) were all higher than those in the control group, and the differences had statistical significance (p < 0.01). However, the erythrocyte sedimentation rate (ESR), deformity index of RBC, blood flow rates in the bilateral middle cerebral arteries (MCA), anterior cerebral arteries (ACA), terminal internal carotid artery (TICA), posterior cerebral arteries (PCA), vertebral arteries (VA) and basilar artery (BA) were significantly lower than those in the control group, and the differences had statistical significance (p < 0.05 or 0.01). CONCLUSION: In elder CHD patients, anomaly is mainly seen in levels of TC, TG and LDL-C with concentrated, adhesive and aggregating blood.
