Association between ambulatory blood pressure monitoring parameters and left ventricular hypertrophy in an Ecuadorian population

In this Ecuadorian cohort, ABPM-derived parameters showed modest cross-sectional discrimination for LVH detection, with daytime SBP demonstrating the best diagnostic balance. These findings are hypothesis-generating and do not support the use of individual ABPM parameters as stand-alone screening tools for LVH. Instead, ABPM should be regarded as a complementary tool for cardiovascular risk stratification and for prioritizing echocardiographic evaluation in resource-limited settings. The proposed thresholds are exploratory and require validation in larger, prospective, multicenter Latin American studies.
