The Association of Salivary Conductivity with Cardiomegaly in Hemodialysis Patients

Patients on maintenance hemodialysis are at high risk for cardiovascular morbidity and mortality. Fluid overload is generally regarded as the main cause of death among them. Cardiothoracic ratio (CTR) by chest plain film routinely performed to evaluate their volumetric states cardiac conditions. We recently reported that salivary conductivity a reliable marker assessing fluid status in healthy adults. This cross-sectional study aims explore association between CTR. Cardiomegaly defined CTR greater than 0.5. A total 129 patients were enrolled, 42 whom (32.6%) had cardiomegaly. with cardiomegaly significantly lower serum osmolality, sodium, conductivity, but higher percentage underlying atrial fibrillation. In multiple linear regression analysis, was negatively associated or sodium level positively correlated older age. further divided into low, medium, groups according tertials levels. There significant trend increment from low (p trend: 0.021). The receiver operating characteristic curves diagnostic ability area under curve equal 0.626 (95% CI: 0.521–0.730, p = 0.02). Moreover, age osmolality independent determinants analysis. work has presented novel approach uncover chronic patients.
