Correlation Study between Hyperuricemia and Chronic Pulmonary Heart Disease: Based on LASSO Regression and Propensity Score Matching
Abstract
Background In recent years, numerous studies have indicated that hyperuricemia (HUA) is a contributing factor to certain diseases. However, whether HUA is a contributing factor to chronic pulmonary heart disease (CPHD) still requires further investigation. Objective To explore the association between HUA and CPHD, aiming to provide a theoretical basis for the management of serum uric acid (SUA) levels in patients with CPHD. Methods A total of1 171 patients with chronic obstructive pulmonary disease (COPD) admitted to the First Affiliated Hospital of Xinjiang Medical University from 2019 to 2023 were included in the study. They were divided into a CPHD group (470 cases) and a COPD group (701 cases) based on whether they had CPHD. General information, laboratory test results, and echocardiographic findings of the patients were collected. LASSO regression was used to select variables, and propensity score matching (PSM) was employed to eliminate the influence of confounding factors. Multivariate Logistic regression analysis was conducted to explore the influencing factors of CPHD in COPD patients. Results The CPHD group had lower proportions of females, Han ethnicity, smokers, drinkers, idiopathic pulmonary fibrosis, chronic bronchitis, bronchial asthma, lymphocyte percentage, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, cardiac output, left ventricular ejection fraction compared to the COPD group. Higher proportions of heart function class 3-4, HUA, pulmonary embolism, congenital heart disease, red blood cell count, neutrophil percentage, SUA, blood urea nitrogen, D-dimer, N-terminal pro-B-type natriuretic peptide, right atrial diameter, right ventricular diameter, left atrial diameter, right ventricular outflow tract diameter, and pulmonary artery diameter were observed in the CPHD group, with statistically significant differences (P<0.05). After variable selection by LASSO regression and PSM, 469 cases were included in both the COPD and CPHD groups. After matching, the CPHD group had higher proportions of heart function class 3-4, HUA, right atrial diameter, right ventricular diameter, right ventricular outflow tract diameter, and pulmonary artery diameter, while lower proportions of bronchial asthma and lymphocyte percentage compared to the COPD group, with statistically significant differences (P<0.05). Multivariate Logistic regression analysis showed that increased HUA, heart function class 3-4, right atrial diameter, right ventricular diameter, and pulmonary artery diameter were risk factors for CPHD in COPD patients (P<0.05), while having bronchial asthma and increased left ventricular end-diastolic diameter were protective factors for CPHD in COPD patients (P<0.05). SUA levels were stratified by quartiles, and multivariate Logistic regression analysis showed that compared to Q1 (SUA<237.31 μmol/L), patients in Q4 (SUA>381.29 μmol/L) had a 1.421-fold inScrsed risk of having CPHD. Conclusion HUA is a contributing factor to the occurrence and development of CPHD. Actively controlling SUA levels may help prevent the occurrence and development of CPHD.
