The Claim
A 25-40% reduction in low-density lipoprotein cholesterol over five years reduces the risk of coronary heart disease death or non-fatal myocardial infarction by approximately 20-35% in both primary and secondary prevention populations, regardless of the method used to lower LDL-C.
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.
Reducing LDL cholesterol by 25-40% over five years lowers the chance of dying from coronary heart disease or having a heart attack by 20-35%, whether the reduction comes from statins, diet, surgery, or other treatments.
See the scientific wording
Lowering low-density lipoprotein cholesterol (LDL-C) by 25-40% over five years reduces the risk of coronary heart disease death or non-fatal myocardial infarction by approximately 20-35% in both primary and secondary prevention populations, regardless of whether LDL-C is reduced by statins, diet, bile acid sequestrants, or ileal bypass surgery, indicating that LDL-C reduction itself is the primary driver of cardiovascular benefit.
When too much LDL cholesterol circulates in the blood, it enters the walls of arteries and builds up as fatty deposits. These deposits attract immune cells that turn into foam cells, forming hard plaques that narrow the arteries. When plaques rupture, they cause blood clots that block blood flow to the heart, leading to heart attacks or death.
What the research says
1 studyStudy: Pleiotropic effects of statins: benefit beyond cholesterol reduction? A meta-regression analysis.
This study found that lowering bad cholesterol by any method — whether with pills, diet, or surgery — reduces heart disease risk by about the same amount: for every 1% drop in cholesterol, heart risk drops 1%. This means the cholesterol drop itself is what helps, not other effects of the drugs.
