Effects of Statin Therapy on Vascular Properties and Outcomes in Diastolic Heart Failure Patients
This study is currently recruiting participants.
Verified by University of Wisconsin, Madison, December 2008
Sponsored by: University of Wisconsin, Madison
Information provided by: University of Wisconsin, Madison
ClinicalTrials.gov Identifier: NCT00585611
  Purpose

The study is designed to define the underlying vascular abnormalities present in patients with diastolic heart failure and test the effect of a therapy aimed at vascular abnormalities. This study is designed to investigate the effects of therapy with atorvastatin in subjects with diastolic heart failure to improve abnormalities of vascular and myocardial structure and function, with particular emphasis on arterial stiffness and endothelial dysfunction.

Official Title: Effects of Statin Therapy on Vascular Properties and Outcomes in Diastolic Heart Failure Patients

Further study details as provided by University of Wisconsin, Madison:

Primary Outcome Measures:
  • Change in carotid-femoral pulse wave velocity (CFPWV) in the statin treated vs. control group [ Time Frame: 6 months after initiation of intervention ] [ Designated as safety issue: No ]
  • Change in Flow Mediated Dilation in the statin treated vs. control group [ Time Frame: 6 months after initiation of intervention ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Composite cardiovascular endpoint incorporating quality of life (QOL) assessment + hospitalizations for cardiovascular disease and mortality [ Time Frame: 6 months after initiation of intervention ] [ Designated as safety issue: No ]
  • Changes in submaximal exercise capacity measured by 6-minute walk test [ Time Frame: 6 months after initiation of intervention ] [ Designated as safety issue: No ]

Estimated Enrollment: 40
Study Start Date: December 2005
Estimated Study Completion Date: December 2010
Estimated Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Experimental Drug: Atorvastatin
Atorvastatin - 40 mg orally daily for 6 months
2: Placebo Comparator Other: placebo
placebo

Detailed Description:

Forty subjects will be given either drug (atorvastatin 40 mg) or placebo in a randomized fashion once daily for six months. Using echocardiography, tonometry, and flow mediated dilation of conduit arteries and arterioles, baseline cardiovascular anatomy and physiology will be defined. Subjects that enroll in the study will be required to come in for 5 study visits. The initial visit is a screening visit; subject consent is obtained and an echocardiogram is performed as well as blood tests. At the randomization visit (4-14 days following screening), the subject will be provided with drug or placebo in a blinded fashion.Also at this visit, subjects will be asked to do a 6 minute walk, QOL questionnaire, and vascular function testing. There will be follow-up study visits at 1 and 3 months following randomization. At each follow-up visit a medical history, pill count and brief physical examination will be performed, a repeat QOL questionnaire administered, and blood tests to assess safety of the statin therapy. At 6 months, the final study visit will occur. At this visit a full history and detailed physical examination will be performed. Repeat echocardiogram, 6 minute walk test, QOL questionnaire, and vascular function examinations will be performed.
