For decades, millions of patients have faced a quiet dilemma: accept the muscle pain that statins bring, or abandon the protection those drugs offer against heart attack and stroke. Researchers at McMaster University have now traced the biological roots of that suffering, identifying a chain reaction in which statins disrupt muscle energy production and trigger an immune response that damages tissue. Published in Science Advances, the work suggests that the mechanism causing harm and the mechanism lowering cholesterol may operate independently — a distinction that, if confirmed, could one day
