Circadian Disruption And Cardiovascular Risk In Young Adults With Hypertension

This prospective observational study will investigate whether circadian disruption is associated with higher blood pressure and a less favorable cardiovascular profile in young adults aged 18 to 45 years with essential arterial hypertension. Participants will undergo 14 days of wrist actigraphy using the CamNtech MotionWatch 8, 24-hour ambulatory blood pressure monitoring, cardiovascular assessment, laboratory testing, and validated questionnaires assessing perceived stress and insomnia symptoms. Circadian disruption will be classified using a predefined five-component research index based on actigraphy measures. Participants with three or more abnormal circadian indicators will be classified as Circadian Disruption Index-positive and compared with participants with zero to two abnormal indicators. The primary outcome is mean 24-hour systolic blood pressure. Secondary outcomes include nocturnal blood pressure patterns, cardiac structure and function, heart-rate variability, stress, insomnia symptoms, and individual circadian measures. The Circadian Disruption Index is a study-specific research classification and is not intended to diagnose a circadian rhythm sleep-wake disorder.

Fixed-dose Combination of an Angiotensin Receptor Blocker and Thiazide Diuretic for Essential Hypertension

This is a phase III, non-inferiority, randomized, double-blind, double-dummy, active-controlled, multicenter study to compare the efficacy and safety of N0877 versus double combination with already established efficacy on systolic blood pressure (SBP) in the sitting position in the medical office in patients with SAH after 8 weeks of treatment.
