Are statins beneficial for chronic heart failure?

There is controversy about the role of statins in chronic heart failure. Even though it is clear they decrease inflammatory markers and probably improve some echocardiographic parameters, it is not clear if they impact clinically important outcomes. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified six systematic reviews including 21 randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded statins in chronic heart failure do not decrease mortality, and might lead to little or no decrease in hospitalizations for heart failure or other clinical outcomes.
