Inflammation and Heart Disease: The Link Most Cholesterol-Only Narratives Miss

The Inflammatory Hypothesis of Atherosclerosis

Atherosclerosis - the plaque build-up that underlies most heart attacks and strokes - is fundamentally an inflammatory disease. The "response to injury" model, pioneered by Russell Ross in the 1970s, describes atherosclerosis as an inflammatory response in the arterial wall to lipid deposition, not simply a passive accumulation of cholesterol.

This means that the same circulating LDL particle causes more damage in the presence of elevated inflammation - explaining why CRP predicts cardiovascular events independently of LDL.

The JUPITER Trial

The 2008 JUPITER trial enrolled 17,802 adults with normal LDL (below 130 mg/dL) but elevated high-sensitivity CRP (hsCRP above 2 mg/L). Randomisation to rosuvastatin (a statin) versus placebo reduced major cardiovascular events by 44% and all-cause mortality by 20%. The trial demonstrated that inflammation markers predict risk independently of LDL - and that statins have anti-inflammatory effects beyond LDL lowering.

"The JUPITER results changed how we think about cardiovascular risk. Inflammation is not a footnote to the lipid story - it is co-authoring it." - Dr. Paul Ridker, Harvard Medical School

What Raises hsCRP

• Visceral adiposity (particularly waist-to-height ratio above 0.5)
• Chronic psychological stress
• Sedentary behaviour
• Poor sleep (both short and fragmented)
• Smoking and alcohol
• Periodontal (gum) disease - a surprisingly strong and specific predictor
• Ultra-processed food heavy diet

Anti-Inflammatory Lifestyle Interventions

Inflammation and Heart Disease in Practice

Include hsCRP in your cardiovascular risk assessment - it is a cheap, standard blood test. A result above 2 mg/L warrants attention to inflammation sources: sleep, stress, diet, exercise, and dental health. The interventions that reduce inflammation are the same ones that reduce LDL, blood pressure, and insulin resistance - reinforcing that lifestyle change has multiple simultaneous cardiovascular benefits.
