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.

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.

Inclusion Criteria:

• Signed informed consent,

• Age > 18,

• Ejection fraction ≥ 50%,

• hospitalization for heart failure in the last 6 months and

• current NYHA Class II-IV symptoms, OR

  1. ECG or echocardiographic evidence of moderate/severe left ventricular hypertrophy,
  2. chest x-ray evidence of pulmonary congestion

Exclusion Criteria:

• Uncontrolled hypertension (BP > 150/100)
• Significant valvular disease.
• Atrial fibrillation
• Known familial hypertrophic cardiomyopathy or obstructive hypertrophic cardiomyopathy.
• Restrictive cardiomyopathy or systemic illness known to be associated with infiltrative heart disease (i.e. amyloidosis, sarcoidosis, hemochromatosis).
• Cor pulmonale or other cause of right heart failure not related to LV dysfunction.
• Clinically significant pulmonary disease.
• Pericardial constriction or hemodynamically significant pleural effusion.
• Uncontrolled arrhythmia.
• Any systemic condition other than heart failure that may limit survival to less than 2 years.
• Advance renal disease (serum creatinine > 3.0 mg/dl or on dialysis)
• Known intolerance or allergy to HMG CoA reductase inhibitors
• Uncontrolled hyper- or hypothyroidism.
• Any subject characteristic that may interfere with study compliance, such as baseline dementia, substance abuse, history of non-compliance with medications or appointments.
• Prisoners or other vulnerable populations.
• Any woman of child-bearing age with a documented positive pregnancy test.
• Subject is receiving therapy with other investigational therapy or is participating in any other clinical trial.
