The purpose of this study is to examine the the effect of the HMG-CoA reductase inhibitor Rosuvastatin on left ventricular remodeling in patients with dilated cardiomyopathy.

• Chronic heart failure (HF) is one of the most important public health problems in cardiovascular medicine.
• Idioatic dilated cardiomyopathy (CMP) represents the final common expression of primary myocardial damage produced by a variety of as yet undefined myocardial insults, producing areas of interstitial and perivascular fibrosis, particularly of the left ventricle. Chronic HF, including CMP, is a progressive disease with high morbidity and mortality, suggesting that important pathogenic mechanisms remain active and unmodified by the present treatment modalities. The presence of chronic inflammation in patients with chronic heart failure has been widely recognized and coupled with persistent immune activation may represent such unmodified mechanisms.

The effect of statin therapy on lipids are well known, but recent studies suggest that the beneficial effects of statins also may be related to their anti-inflammatory properties.

To further elucidate this issue we want to study the potent new statin Rosuvastatin on myocardial function and remodeling and their relation to inflammatory markers in patients with IDCM. As hyperlipidemia is not involved in the pathogenesis of IDCM, as opposed to HF secondary to CAD, such studies will also be an interesting approach in separating the lipid lowering from other effects of these medications in HF.

• Have given written informed consent
• No planned heart transplantation
• Female of potential childbearing age must have a negative serum pregnancy test within 7 days prior to enrollment. Effective contraception must be used during the trial and for 6 weeks following discontinuation of the study medication, even where there has been a history of infertility.

Exclusion Criteria:

• Evidence of unstable disease
