| Objective To explore the risk factors of coronary heart disease with heart failure complicated with renal failure, and toconstruct a multiple logistic regression model bases on this.Methods The clinical data of 478 patients with coronary heart diseaseand heart failure admitted to The Third People's Hospital Directly Under He'nan Province from September 2018 to July 2022 were ana-lyzed retrospectivel, and they were randomly assigned into modeling group (n=335) and verification group (n=143) according to the ratio of 7∶3. According to the complication of renal failure, the patients in the modeling group were further divided into concurrent group andnon concurrent group. The risk factors of coronary heart disease with heart failure patients complicated with renal failure in the model-ing group were analyzed by single factor and multiple factor logistic regression analysis, and a multiple logistic regression model was es-tablished. The receiver operating characteristic (ROC) curve, the Hosmer-Lemeshow goodness of fit test and decision curve method (DCA) were used to internal and external test the model.Results Among 478 patients with coronary heart disease and heart failure,113 patients were complicated with renal failure (23.64%), and 86 cases in 335 patients in the modeling group were complicated with renal failure (24.48%),and 31 cases in 143 patients in the validation group were complicated with renal failure (21.68%). The propor-tions of age ≥ 60 years old,New York Heart Association (NYHA) cardiac function class Ⅳ, primary hypertension, diabetes, atrial fibril-lation, diuretics,left ventricular posterior wall thickness (LVPWT)>11 mm, left ventricular ejection fraction (LVEF)≤ 45%, blood ureanitrogen (BUN)>6 mmol/L,serum creatinine (Scr)>133 μmol/L, serum uric acid >420 μmol/L, cystatinC (CysC)>1.10 mg/L, N-terminal pro B-type natriuretic peptide (NT-proBNP) >3 000 ng/L and hemoglobin (Hb)<110 g/L in the concurrent group were higher than those in the non concurrent group (P<0.05).The collinearity diagnosis showed that LVPWT, LVEF, BUN, blood uric acid and NT-proBNP hadcollinearity problems.On this basis, multivariate logistic regression analysis was performed, and the results showed that the age ≥ 60years old, NYHA cardiac function class Ⅳ, history of primary hypertension, history of diabetes, history of atrial fibrillation, history ofdiuretics, LVEF≤45%,BUN>6 mmol/L, Scr>133 μmol/L,CysC>1.10 mg/L, Hb<110 g/L were all risk factors for coronary heart diseasewith heart failure patients complicated with renal failure(P<0.05). According to the results of logistic regression analysis, the logistic re-gression model for risk prediction was constructed. Through internal test, the area under the ROC curve was 0.84[(95%CI: 0.78, 0.89)], and the sensitivity and specificity were 81.82% and 77.42% respectively, while the Hosmer-Lemeshow goodness of fit test showed P= 0.787.External test was performed using the validation group data, and the area under the ROC curve was 0.83[95%CI: (0.76,0.89)],and the sensitivity and specificity were 80.00% and 77.00% respectively,while the Hosmer-Lemeshow goodness of fit test showed P=0.776. DCA curve showed that when the threshold probability was 0~0.9,the net benefit of logistic regression model for predicting the risk ofcoronary heart failure complicated with renal failure was higher.Conclusions Old age, NYHA heart function class Ⅳ,history of prima-ry hypertension,history of diabetes, history of atrial fibrillation,history of diuretics,LVEF≤45%,BUN>6 mmol/L, Scr>133 μmol/L,CysC>1.10 mg/L, Hb<110 g/L are all risk factors for coronary heart disease and heart failure patients complicated with renal failure. The riskprediction logistic regression model established based on this result has good predictive value,and it can help clinical workers to screenhigh-risk groups complicated with renal failure early,so as to intervene in time and reduce the incidence of renal failure. |
