Abstract:

Objective To investigate the risk factors of arteriosclerosis obliterans (ASO) in patients with cardiac insufficiency, and to construct and verify the nomogram risk prediction model. Methods A total of 319 patients with cardiac insufficiency were selected. According to whether there was lower extremity arterial stenosis or occlusion in the lower extremity, patients were divided into the ASO positive group (n=161) and the ASO negative group (n=158). Gender, age, history of smoking, history of drinking, history of hypertension, New York heart association (NYHA) cardiac function grade, triglycerides (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), homocysteine (HCY), glycosylated hemoglobin (HbA1c), N-terminal pro-brain natriuretic peptide (NT-proBNP), high sensitivity cardiac troponin T (hs-cTnT), ankle-brachial index (ABI) and left ventricular ejection fraction (LVEF) were collected after admission. Logistic regression was used to analyze the risk factors of ASO in patients with cardiac insufficiency, so as to establish and verify the nomogram risk prediction model. Results Compared with the ASO negative group, the ASO positive group had higher male ratio, high proportion of hypertension, higher smoking rate, high proportion of NYHA cardiac function grade Ⅱ-Ⅲ, higher levels of HbA1c, TG, TC, LDL-C and HCY, and lower ABI (P<0.05). Logistic regression analysis showed that male,hypertension, smoking, NYHA cardiac function grade Ⅱ-Ⅲ,higher levels of TG, TC, LDL-C, and HCY were independent risk factors for ASO in patients with cardiac insufficiency. The nomogram risk prediction model constructed on this basis was verified by Bootstrap internal verification. The Hosmer-Lemeshow test showed that the model had good goodness of fit (χ2=0.602,P>0.05). The C-index of the model was 0.856 (95%CI: 0.815-0.896). Spearman correlation analysis showed that LVEF was positively correlated with ABI (rs=0.228,P<0.01). NYHA cardiac function grade, NT-proBNP and hs-cTnT were negatively correlated with ABI (rs=-0.296, -0.303 and -0.268, P<0.01). Conclusion Male, hypertension, smoking, NYHA cardiac function grade Ⅱ-Ⅲ, higher levels of TG, TC, LDL-C and HCY are independent risk factors for ASO in patients with cardiac insufficiency. The established nomogram prediction model could effectively assess the risk of ASO in patients with cardiac insufficiency.
