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.

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.

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

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.

Lowering bad cholesterol really aggressively might not help people live longer because while it prevents heart attacks, it could also cause other problems that balance things out.

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