Circadian Mechanisms of Cardiovascular Risk in Obesity
Source: ClinicalTrials.gov · Last updated 18 May 2026
Brief summary (registry, in English)
A multidisciplinary investigation examining the circadian mechanisms regulating cardiovascular (CV) risk, with an additional focus on obesity. Specifically, in a valid circadian protocol, the investigators aim to study resting cardiovascular risk markers and the reactivity of circadian rhythms in these risk markers to standardized stressors. It is intended to compare results in lean and obese individuals to determine if there are specific risks across the circadian cycle specific to obesity. Furthermore, using an exploratory approach, the investigators propose to explore impairment in pre/post synaptic function in the cardiac left ventricle.
