For heart failure patients younger than 70, having lower 'bad' cholesterol might actually be linked to a higher chance of dying.

For people with very bad heart problems, having lower 'bad' cholesterol at the start of treatment might actually lead to a higher chance of dying over 20 years, especially if they're younger than 70 or taking cholesterol-lowering drugs.

This claim says that when people with very serious heart problems have higher 'bad' cholesterol levels at the start of treatment, they might actually live longer than those with lower levels.

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.

About half of the people who have serious heart problems also have low 'bad' cholesterol levels.

High LDL cholesterol doesn’t actually raise your chances of getting heart disease, according to some studies that question the long-standing belief about cholesterol and heart health.
