Heart health 101.

Cardiovascular disease is still the number-one killer in most of the Western world. The upside: it's also the domain where you have the most leverage. Blood vessels age slowly — for years before you notice anything — and the right interventions at the right time make a difference measured in decades.

Why heart and vessels are decisive

Cardiovascular disease still causes a large share of all deaths in Europe.5 The striking thing is that the vast majority was preventable. The INTERHEART study showed that nine modifiable risk factors together account for more than 90% of global heart-attack risk — independent of country, age or sex.7

The trouble is that vascular damage builds silently. Your arteries start to harden in your twenties; symptoms tend to appear decades later — and by then much of the damage is chronic. For many people the first heart attack is also the first 'symptom'. Prevention is therefore not a matter of waiting for complaints.

How your blood vessels age

The core process is atherosclerosis: cholesterol-carrying particles — chiefly LDL and lipoprotein(a) — accumulate in the artery wall and trigger a chronic inflammatory response. Over years this builds plaques that narrow the vessel or, when they rupture, cause an acute heart attack or stroke.1

What drives this isn't total cholesterol so much as the number of apoB-containing particles. Every LDL and Lp(a) particle carries one apoB molecule; more particles, more chance one of them lodges in the wall. That's why apoB outperforms LDL as a risk predictor — especially in people with normal LDL but many small, dense particles (typical with insulin resistance or excess weight).2

The real risk factors — beyond cholesterol

Cholesterol is one of nine modifiable factors in INTERHEART that together explain over 90% of risk. The other eight: smoking, high blood pressure, diabetes and insulin resistance, abdominal obesity, psychosocial stress, low fruit and vegetable intake, low physical activity, and excessive alcohol.7

Two underrated markers a standard cholesterol panel misses: lipoprotein(a) and high-sensitivity CRP. Lp(a) is largely inherited, raises cardiovascular risk independent of LDL, and affects roughly one in five people — measuring it once in your life is enough.3 hsCRP is a marker of chronic low-grade inflammation that contributes independently to vascular damage.6

What you can measure about your heart

A complete cardiovascular screen works in three layers. First the classic lipid panel — total cholesterol, LDL, HDL, triglycerides and the ratios. Important, but no longer sufficient for good prevention by modern guidelines.4

Second is where the leverage is: apoB and lipoprotein(a) reveal the actual particle burden and let you direct interventions far more precisely.[2,3] Plus HbA1c for insulin resistance — a frequently missed cardiovascular factor — and hsCRP for inflammation. The Optimize Baseline covers this layer by default.

Third is context: blood pressure measured at home on multiple occasions (more reliable than a single GP reading),9 waist circumference, and — when risk is elevated — a coronary artery calcium score via CT. The ESC SCORE2 tool combines these into a 10-year cardiovascular risk estimate.10

What you can do

The evidence base is encouragingly strong. PREDIMED — a large randomised trial in Spain — showed that a Mediterranean dietary pattern (extra-virgin olive oil, nuts, fish, legumes, vegetables; less red meat and refined carbohydrate) cuts cardiovascular events by about 30% versus a standard low-fat diet.8

Exercise — at least 150 minutes of moderate-intensity per week, plus two resistance sessions — moves both blood pressure and insulin sensitivity. Stopping smoking sits in the same category as the most effective medications: within five years, heart-attack risk approaches that of a never-smoker.7

For people with elevated apoB, a statin (or comparable LDL-lowering therapy) is the most evidence-based step. Not out of preference for medication, but because cardiovascular benefit per mmol/L of LDL reduction is consistent and large. At Optimize our physician will flag whether that conversation makes sense for your numbers.

When to involve a physician

Immediately (112 / 911): sudden chest pain or pressure lasting more than a few minutes, especially with radiation to the arm, jaw, back or stomach; shortness of breath; cold sweat; nausea. In women it can present more subtly (fatigue, chest pressure, breathlessness) but deserves equal urgency.

By appointment with your GP or cardiologist: a family history of early heart attack (men under 55, women under 65), known elevated Lp(a), persistently raised blood pressure, or apoB well above the optimal range. At Optimize every result is reviewed by our physician and we reach out proactively when your values warrant follow-up.
