Performance of different adiposity measures for predicting left ventricular remodeling in Chinese hypertensive youth

There is no consistent conclusion on which adiposity measure is best to predict cardiovascular risk factors in youth. The present study aims to assess the performance of body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) in predicting abnormal left ventricular structure in Chinese hypertensive youth. A total of 1180 youth aged 6–17 years with hypertension from the China Child and Adolescent Cardiovascular Health Study were included in this study. Logistic regression model, receiver operator characteristic (ROC) curve analysis and net reclassification improvement (NRI) method were used to assess performance of BMI, WC, and WHtR in predicting left ventricular hypertrophy (LVH) and left ventricular geometry (LVG). A 1-standard deviation increment in any of three indexes in predicting LVH and LVG were similar, e.g., with the odds ratios and 95% confidence intervals of 1.34 (1.16–1.55), 1.25 (1.08–1.45) and 1.40 (1.20–1.62), respectively. In addition, ROC analysis and NRI method confirmed the similar performance of three adiposity indexes in predicting LVH and LVG. In conclusion, BMI, WC and WHtR had similar performance in predicting abnormal left ventricular structure in Chinese hypertensive youth, but all three indexes had limited value in prediction. WHtR is a simple and convenient adiposity index for screening youth at high risk of target organ damage.

Analysis of Risk Factors for Changes in The Doppler Echocardiographic Indexes of Patients With Gout

Objective: The analysis of risk factors for changes in the Doppler echocardiographic indexes of patients with gout with different serum uric acid (SUA) levels were explored to provide clinical evidence for the early diagnosis and treatment of abnormal heart function in this patients.Methods: We obtained information of 227 patients with primary gout (intermittent period), the left ventricular structure and functional index were measured using echocardiography and multivariate logistics regression was used to analyze the risk factors related to changes in heart function in patients with gout.Results: Logistic regression analysis showed that the course of disease and cystatin C (Cys-C) were risk factors for the increase of left atrial volume index (LAVI) (OR=1.14, 105.47; 95% CI, 1.01-1.28, 1.18-9468.03). Age, body mass index (BMI), course of disease, and diabetes were risk factors for the increase of the ratio of diastolic peak early transmission flow velocity to peak early diastolic mitral annulus velocity (E/Em) (OR=1.04, 1.17, 1.14, 4.82; 95% CI, 1.01-1.08, 1.03-1.33, 1.02-1.27, 1.07-21.71). However, the percentage of neutrophils percentage (NE%) and lymphocytes percentage (LY%) might reduce the risk of left ventricular wall thickening, whereas HGB might reduce the risk of increasing E/Em (OR=0.80, 0.75, 0.94; 95% CI, 0.66-0.96, 0.60-0.93, 0.89-1.00).Conclusion: Our findings suggest that BMI, course of disease, diabetes, and Cys-C are risk factors for decreased left ventricular function. Furthermore, HGB, NE%, and LY% appear to have a weak protective effect for the remodeling of left ventricular structure and function.
