Sleep Quality and Mechanisms of Cardiovascular Risks in Adults With Hypertension

Study Description
Brief Summary:
The objective of this study is to elucidate the potential mechanisms responsible for the increased risk of cardiovascular disease among patients with hypertension and comorbid insomnia.

Condition or disease Intervention/treatment Phase
Hypertension Insomnia Behavioral: Cognitive Behavioral Therapy for Insomnia (CBT-I) Not Applicable

Detailed Description:
The investigators propose to utilize a behavioral intervention to manipulate sleep quality in 150 adults with hypertension and comorbid insomnia, who will receive a 6-week Cognitive Behavioral therapy for Insomnia (CBT-I) intervention, which has been shown to markedly improve sleep quality and promote consolidated sleep in approximately 60% of those treated. A lowering of nighttime blood pressure is one of several proposed mechanisms to be examined.
