Surprising Findings
More intensive cholesterol lowering was linked to *lower* kidney stress, not higher.

Practical Takeaways
If you have heart disease, talk to your doctor about whether aiming for LDL below 55 mg/dL is right for you.

For people with heart disease from clogged arteries, getting their bad cholesterol down to around 56 doesn’t cause more serious side effects than staying at 66, and it’s safe to keep it that low for at least three years.
For people who already have heart disease, aiming to get their 'bad' cholesterol (LDL) below 55 mg/dL cuts their risk of serious heart problems by about one-third over three years compared to aiming for below 70 mg/dL — and it doesn’t seem to cause more side effects.
If you have heart disease from clogged arteries, getting your bad cholesterol down to around 56 mg/dL instead of 66 mg/dL can cut your risk of heart attacks or strokes by about a third over three years. For every 32 people treated this way, one person avoids a major heart problem.
For people with heart disease from clogged arteries, keeping bad cholesterol really low—below 55—might be better for your kidneys than keeping it just under 70, especially if you're getting procedures to open up blood vessels.
If you've had heart problems before, aiming to get your 'bad' cholesterol really low—below 55—cuts your risk of another heart issue by about a third compared to keeping it just under 70.
