Lowering 'bad' cholesterol (LDL-C) keeps your heart healthier over the long term, and the more time passes, the same level of protection continues—no weakening.

Assessment Explanation
This claim is supported by long-term randomized controlled trials (RCTs) of statins and PCSK9 inhibitors, which show sustained reduction in cardiovascular events proportional to LDL-C lowering over 5+ years. The stability of effect size across time is a well-documented phenomenon in lipid-lowering trials (e.g., IMPROVE-IT, FOURIER, ODYSSEY OUTCOMES). The claim uses precise language ('does not weaken', 'remains stable') consistent with observed data, and does not overgeneralize beyond the evidence base. A definitive verb is appropriate because the effect is consistently replicated across multiple high-quality studies with long-term follow-up.
More Accurate Statement
“The cardiovascular benefit of LDL-C reduction does not weaken over time during follow-up periods of up to several years, as the magnitude of risk reduction remains stable regardless of treatment duration.”

This study looked at whether lowering 'bad' cholesterol keeps protecting your heart over many years — and found that it does. The longer people were treated, the same level of protection stayed strong.
