Condition: Obesity · Cardiovascular Diseases · Hypertension · Sponsor: University of Alabama at Birmingham
Obese individuals have a higher prevalence of nocturnal hypertension and non-dipping blood pressure (BP). These conditions are associated with an increased risk of cardiovascular (CV) events and death. Natriuretic Peptides (NPs) are hormones produced by the heart which directly regulate BP by causing dilation of blood vessels and by removing sodium and water from the body. NPs have a 24-hour day-night rhythm and this controls the day-night rhythm of BP as well. The NP-BP rhythm relationship is broken down in obese individuals. Obese individuals also have lower circulating NP levels. Lower circulating levels of NPs and elevated renin hormone (a part of the Renin-Angiotensin-Aldosterone System \[RAAS\]) at nighttime may contribute to the high nocturnal blood pressure in obese individuals which puts them at a higher risk of developing CV events. This current study seeks to determine the biological implications of chronopharmacology for synchronizing NP-RAAS-based blood pressure therapy with the physiological diurnal rhythms to restore the normal diurnal rhythm of blood pressure in obese individuals.
