Evaluating insomnia treatment to lower heart disease risk in PTSD patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the relationship between insomnia and cardiovascular disease (CVD) risk in individuals diagnosed with posttraumatic stress disorder (PTSD). It aims to determine if treating insomnia through Cognitive Behavioral Therapy for Insomnia (CBT-I) can improve biomarkers associated with CVD risk. Participants will undergo assessments of vascular function, blood pressure, and sympathetic nervous system activity, alongside their treatment. The study seeks to clarify the mechanisms linking PTSD, insomnia, and cardiovascular health.
