Fu M, Hu X, Sun S, et al. - A retrospective study was conducted to explore the association between masked hypertension measured by ambulatory blood pressure monitoring and left ventricular global longitudinal strain. Researchers recruited a total of 308 enrolled participants from Dongguan, China. Individuals were classified into non-hypertension and masked hypertension (MHT) groups. They used linear regression analysis and receiver-operating characteristic curve analysis to investigate the relationships between MHT and global longitudinal strain (GLS) in univariate and multivariate models, and the dose-response curve was plotted to demonstrate their association. Based on the association between MHT and GLS, the results showed that in clinical practice, GLS measurement could facilitate diagnosis for suspected MHT patients and could characterize the extent of left ventricular dysfunction for diagnosed MHT patients.
