The Claim

In adults recovering from acute myocardial infarction, very low absolute follow-up LDL-C levels (<55 mg/dL) are associated with a similar or higher risk of major adverse cardiovascular events compared to LDL-C levels between 55–69 mg/dL, indicating a U-shaped relationship.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

In adults who have had a heart attack, LDL cholesterol levels below 55 mg/dL are linked to the same or higher rates of serious heart problems compared to levels between 55 and 69 mg/dL, suggesting a U-shaped risk pattern.

See the scientific wording

In adults recovering from acute myocardial infarction, very low absolute follow-up LDL-C levels (<55 mg/dL) are associated with a similar or higher risk of major adverse cardiovascular events compared to levels between 55–69 mg/dL, forming a U-shaped relationship that suggests potential harm or confounding at extremely low levels.

Why this might work

When cholesterol drops too low, the body cannot properly repair damaged blood vessels or regulate inflammation, leading to unstable plaques and more heart events.

  1. Study: Long-term outcomes according to absolute value vs. percentage reduction in low-density lipoprotein cholesterol levels after acute myocardial infarction

    After a heart attack, having cholesterol levels below 55 mg/dL didn’t make people safer than keeping them between 55 and 69 mg/dL — in fact, it was linked to similar or higher chances of more heart problems. This suggests that going super low might not help and could even be risky.
