The influence of atorvastatin on parameters of inflammation left ventricular function, hospitalizations and mortality in patients with dilated cardiomyopathy--5-year follow-up.

Abstract

BACKGROUND:

We assessed the influence of atorvastatin on selected indicators of an inflammatory condition, left ventricular function, hospitalizations and mortality in patients with dilated cardiomyopathy (DCM).

METHODS:

We included 68 DCM patients with left ventricular ejection fraction (LVEF) ≤40% treated optimally in a prospective, randomized study. They were observed for 5 years. Patients were divided into two groups: patients who were commenced on atorvastatin 40 mg daily for two months followed by an individually matched dose of 10 or 20 mg/day (group A), and patients who were treated according to current recommendations without statin therapy (group B).

RESULTS:

After 5-year follow-up we assessed 45 patients of mean age 59 ± 11 years - 22 patients in group A (77% male) and 23 patients in group B (82% male). Interleukin-6, tumor necrosis factor alpha, and uric acid concentrations were significantly lower in the statin group than in group B (14.96 ± 4.76 vs. 19.02 ± 3.94 pg/ml, p = 0.012; 19.10 ± 6.39 vs. 27.53 ± 7.39 pg/ml, p = 0.001, and 5.28 ± 0.48 vs. 6.53 ± 0.46 mg/dl, p = 0.001, respectively). In patients on statin therapy a reduction of N-terminal pro-brain natriuretic peptide concentration (from 1425.28 ± 1264.48 to 1098.01 ± 1483.86 pg/ml, p = 0.045), decrease in left ventricular diastolic (from 7.15 ± 0.90 to 6.67 ± 0.88 cm, p = 0.001) and systolic diameters (from 5.87 ± 0.92 to 5.17 ± 0.97, p = 0.001) in comparison to initial values were observed. We also showed the significant increase of LVEF in patients after statin therapy (from 32.0 ± 6.4 to 38.8 ± 8.8%, p = 0.016). Based on a comparison of curves using the log-rank test, the probability of survival to 5 years was significantly higher in patients receiving statins (p = 0.005).

CONCLUSIONS:

Atorvastatin in a small dose significantly reduce levels of inflammatory cytokines and uric acid, improve hemodynamic parameters and improve 5-year survival in patients with DCM.
