The Claim

In older adults with ischemic systolic heart failure, daily administration of 10 mg rosuvastatin for 32.8 months significantly reduces low-density lipoprotein cholesterol by 45% and high-sensitivity C-reactive protein by 37% compared to placebo, but these biomarker reductions are not associated with a reduction in mortality or major cardiovascular events.

Cause and effect
1 study reviewed
In plain English

In older adults with a type of heart failure, taking 10 mg of rosuvastatin daily for about 2.7 years lowers LDL cholesterol by 45% and inflammation markers by 37% compared to a placebo, but this does not lead to fewer deaths or fewer heart attacks or strokes.

See the scientific wording

In older adults with ischemic systolic heart failure, daily 10 mg rosuvastatin significantly lowers low-density lipoprotein cholesterol by 45% and high-sensitivity C-reactive protein by 37% compared to placebo over 32.8 months, demonstrating potent lipid-lowering and anti-inflammatory effects, but these biomarker improvements are not associated with reduced mortality or major cardiovascular events.

Why this might work

Rosuvastatin blocks a key enzyme in the liver that makes cholesterol, which lowers bad cholesterol in the blood. It also reduces a signal that tells the body to make inflammation, which lowers a marker of inflammation. These changes happen, but they do not stop the heart from failing or prevent death or major heart events in older people with this type of heart failure.

What the research says

1 study

  1. Study: Rosuvastatin in older patients with systolic heart failure.

    Taking rosuvastatin lowered bad cholesterol and inflammation in older heart failure patients, just like the claim says — but it didn’t stop them from dying or having heart attacks, which is also what the claim says.
