The Claim
In middle-aged symptomatic patients, those with coronary artery calcification (CAC > 0) and very high LDL-C (≥193 mg/dL) have a 142% higher risk of atherosclerotic cardiovascular disease (ASCVD) events compared to those with LDL-C <116 mg/dL, whereas no such increased risk is observed in patients with CAC = 0, suggesting that extreme LDL-C elevation is associated with ASCVD risk only in the presence of established atherosclerosis.
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.
If you're a middle-aged person with signs of heart disease and calcium in your arteries, having very high 'bad' cholesterol makes your risk of heart problems more than double. But if your arteries are clean, even sky-high cholesterol doesn’t seem to increase your risk.
See the scientific wording
Middle-aged symptomatic patients with coronary artery calcification (CAC > 0) and very high LDL-C (≥193 mg/dL) have a 142% higher risk of ASCVD events compared to those with LDL-C <116 mg/dL, while no such association exists in patients with CAC=0, indicating that extreme LDL-C elevation confers risk only when atherosclerosis is already present.
What the research says
1 studyThe study shows that very high cholesterol increases heart disease risk only in people who already have artery plaque, not in those without it, which is exactly what the claim says.
