Abstract：【Objective】To investigate the changes and clinical significance of lipoprotein a [Lp (A)] and ApoA-1,ApoB in patients with coronary heart disease. 【Methods】 Sixty-five patients with coronary heart disease treated in our hospital from January 2016 to April 2017 were retrospectively analyzed. Data (observation group), while 65 healthy volunteers who were examined in our hospital at the same time were classified as control group. The clinical data and laboratory results of all subjects were collected from the inpatient electronic medical record system to collect age, sex, whether or not they were suffering from chronic diseases such as hypertension, diabetes and hyperlipidemia. The plasma levels of Lp(A), ApoA-1, ApoB and ApoB/ApoA-1 were compared between the two groups. The predictive value of the above laboratory indexes for coronary heart disease (CHD) was evaluated by the (ROC) curve of the operating characteristics of the subjects. 【Results】The serum Lp (A), ApoB, ApoB/ ApoA-1 level in the observation group was significantly higher than that in the control group ( P < 0.05), and the serum ApoA-1 level in the observation group was lower than that in the control group, but the difference was not statistically significant ( P > 0.05). The evaluation of ROC curve showed that ApoB/ApoA-1 was the most effective in the diagnosis of coronary heart disease. The AUC (95%CI) of ROC curve was 0.81(0.74~0.89)and 0.78(0.70~0.86). The optimal diagnostic critical value value of Lp(A),ApoB, ApoB/ApoA-1 was 156.4 mg/L, 0.83 g/L ,1.15. Logistic regression analysis showed that Lp(A)> 156.4 mg/L, ApoB> 0.83 g/L, ApoB/ApoA-1> 1.15 were independent risk factors of coronary heart disease.【Conclusions】The high level of Lp(A), ApoB, ApoB/ApoA-1 in patients with coronary heart disease (CHD) is a potential clinical marker for the diagnosis of CHD. Lp(A)> 0.83 g/L and ApoB/ApoA-1> 1.15 are independent risk factors for coronary heart disease.
