The Claim
Elevated LDL cholesterol levels are not consistently correlated with the presence of heart disease, as approximately half of hospitalized cardiac patients have low or normal LDL levels, which challenges the causal role of LDL cholesterol in the development of atherosclerosis.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
A lot of people with heart problems don't actually have high LDL cholesterol — about half of them have normal or even low levels — so maybe LDL isn't the main cause of heart disease after all.

Elevated LDL cholesterol levels are not consistently correlated with the presence of heart disease, as approximately half of hospitalized cardiac patients have low or normal LDL levels, challenging the causal role of LDL in atherosclerosis.
What the research says
3 studiesThe study shows that in people who already have heart artery plaque, higher LDL cholesterol leads to more heart problems, which goes against the idea that LDL doesn’t matter for heart disease.
Study: The LDL cumulative exposure hypothesis: evidence and practical applications
Just because some heart patients have normal cholesterol doesn’t mean cholesterol isn’t the cause—this study shows that long-term exposure to even moderate levels can lead to heart disease over time.
