Prognostic Value of the Circadian Pattern of Ambulatory Blood Pressure for Multiple Risk Assessment

Summary

The HYGIA study was designed to investigate prospectively 1. the prognostic value of ambulatory blood pressure (BP) monitoring among subjects primarily evaluated at primary care settings 2. the impact of changes in ambulatory BP during follow-up in cardiovascular, cerebrovascular, metabolic, and renal risk in hypertensive patients 3. the influence of circadian time of treatment in cardiovascular, cerebrovascular, metabolic, and renal risk in hypertensive patients 4. the prevalence of an altered BP profile as a function of antihypertensive treatment, circadian time of treatment, age, and presence of diabetes, among other factors.
