Left atrial systolic force (LASF) has been recently reported to be associated with prolonged left ventricular (LV) relaxation and concentric LV geometry in a clinical setting. This study analyzes the association of increased LASF to LV geometry and function in hypertensive patients from a population study. ⋯ Enhanced LASF is associated with LV hypertrophy, normal LV chamber function, increased cardiac output, and prolonged relaxation. The LASF is a preload-dependent measure.

Morning blood pressure (BP) surge in ambulatory BP monitoring was a risk factor for stroke in our previous study. We studied the determinants of the morning minus evening systolic BP difference (ME difference) in self-measured BP monitoring, as a possible risk factor for stroke in medicated hypertensive patients. ⋯ Older age, beta-blocker use, and regular alcohol drinking were significant determinants of the exaggerated ME difference in medicated hypertensive patients.
