Abstract

Abstract : Objective: Many studies suggested that central aortic systolic blood pressure (CASP) has been shown to be a stronger predictor of target-organ damage and cardiovascular events than brachial systolic blood pressure (BSBP), but there was no dating about whether CASP can predict prolonged QRS duration more than BSBP. We examined the association of CASP and BSBP with QRS duration in rural community residents. Figure. No caption available. Design and method: This was a retrospective study. A total of 490 rural community residents were all from the Liaobu town, Guangdong, China, which a community cohort was managed by Guangdong general hospital. All participants underwent physical examinations, regular laboratory examinations, standard resting 12-lead ECG, and noninvasive CABP measurements. Linear regression was assessed the associations of QRS duration with clinical conditions. Logistic regression analyses were performed to determine the independent predictor of prolonged QRS duration. Receiver operating characteristic (ROC) curve was used to evaluate the utility of CASP for prolonged QRS duration. Results: We retrospectively analyzed 490 rural community residents who all of them CASP, BSBP and standard resting 12-lead electrocardiogram were measured. The prolonged QRS duration group showed higher CASP (139.38 ± 11.67 vs 135.36 ± 16.22, P = 0.031) and BSBP (136.03 ± 6.74 vs124.44 ± 13.01, P < 0.001) as compared with controls. Multivariate linear regression analysis showed that CASP, BSBP and heart rate were independently affecting QRS duration. Logistic regression analyses showed that CASP (OR 1.057, 95%CI: 1.027, 1.088, P < 0.001) and BSBP (OR 1.056, 95% CI: 1.027, 1.086, P = 0.032) were independent predictors of prolonged QRS duration after adjustment for age, sex, body mass index, heart rate. CASP had a better predictive value for prolonged QRS duration than (AUC: 0.793 vs 0.601, P < 0.001) BSBP. Conclusions: Our findings showed that both CASP and BSBP were risks for prolonged QRS duration, but CASP can better predict prolonged QRS duration more than BSBP.
