Vascular Age: Pressure & flow network integrity

Think of your circulation the way an engineer thinks about a plant's distribution network. Pipes rarely fail from one dramatic event — they fail from years of pressure load, material fatigue and accumulated sediment. Your vessels carry a pressure pulse with every heartbeat, for decades, and vascular age measures how well that network is holding up.

Vascular age sets the mechanical environment every other organ lives inside. Elevated pressure and arterial stiffness are not abstract risk points on a chart; they apply continuous physical stress to the heart, brain, kidneys and microvasculature, and over time that stress becomes biology.

The vascular dial is one of eight that make up your Longevity Score, and carries 18% of the composite. It is scored from 4 biomarkers against book-based scoring ranges rather than standard clinical cut-offs. These ranges are not a diagnosis or an individual treatment target.

Biomarkers scored in this dial

You do not need all of them. Blank values are excluded from scoring, never counted as zero. The markers tagged short-form input appear in the calculator's short form; this is not a recommendation to obtain tests.

How fast each marker actually responds

Markers move on very different timescales, and treating a slow one as a steering signal is the most common way people conclude that nothing is working. Steer with the fast signals; audit with the slow ones.

Practical rule. Steer with blood pressure trends and the inputs you control. Audit with stiffness and plaque imaging when they are genuinely indicated.

How to improve your vascular age

Nutrition

• Adopt a DASH or Mediterranean dietary pattern — the most evidence-backed BP-lowering diets
• Reduce sodium to <1.5g/day (not just 'low salt' — read labels; processed foods are the main culprit)
• Increase dietary nitrates: arugula, beets, spinach, and dark leafy greens support nitric oxide production
• Add potassium-rich foods (avocado, banana, sweet potato) — potassium counteracts sodium's BP effects
• Minimize alcohol: even 1–2 drinks/day raises systolic BP meaningfully
• Dark chocolate (85%+, 20–30g/day) has modest but real endothelial benefit via flavanols

Training

• Zone 2 cardio 150–180 min/week (conversational pace, nasal breathing): primary BP-lowering lever
• Isometric exercises (wall sits, planks 3×/week): meta-analyses show isometrics lower BP more than isotonic cardio alone
• Resistance training 2–3×/week supports vascular tone and reduces arterial stiffness
• Avoid sustained heavy breath-holding (Valsalva) with very high BPs — check with physician first

Supplements

• Magnesium glycinate — 300–400 mg/nightevidence A
  Meta-analysis supports modest BP reduction; also improves sleep quality
• Omega-3 (EPA+DHA) — 2–4g/day with foodevidence A
  Reduces triglycerides, lowers vascular inflammation, modest direct BP effect
• Aged garlic extract — 600–1200 mg/dayevidence B
  Consistent mild BP reduction in RCTs; also reduces arterial stiffness
• CoQ10 — 100–200 mg/day with fatevidence B
  Modest BP-lowering effect in meta-analyses; essential for vascular mitochondrial function
• L-Citrulline — 3–6g/dayevidence B
  Supports nitric oxide pathway; improves endothelial function and arterial compliance

Evidence tiers: A = consistent human RCT support, B = mixed or mechanistic, C = early or anecdotal.

Lifestyle

• Home BP monitoring: morning and evening, 3 readings averaged — eliminate white-coat effect
• Sleep 7–9 hrs with consistent wake time: each hour of sleep debt raises SBP ~2–5 mmHg
• Sauna 3–4×/week (20 min at 80°C): Finnish data shows 50% lower CV mortality in frequent sauna users
• Cold exposure (cold showers/plunges): improves vascular tone and sympathetic calibration
• Reduce chronic psychological stress — cortisol directly drives vasoconstriction

How this dial interacts with the others

No dial moves alone. If progress here has stalled, the cause is often sitting in one of these:

• Metabolic age — Glucose volatility and insulin resistance injure the endothelium and drive stiffness over time.
• Inflammatory age — Inflammation makes the vessel lining stickier and less responsive.
• Atherogenic age — Particle burden decides whether sediment actually accumulates in the network.
• Structural age — Movement capacity determines how much maintenance flow you can sustain.

Assessment inputs to discuss

These are inputs for the assessment, not tests everyone needs. Discuss with your clinician which, if any, are appropriate and whether existing results can be used.

A blood pressure cuff does not directly measure arterial stiffness. Discuss whether additional measurements are appropriate with your clinician.

When to retest

Re-measure home BP trend at 6 weeks. Full panel (including CIMT repeat if accessible) at 12 weeks.

Frequently asked questions

What does the vascular dial measure?

Pressure & flow network integrity. Think of your circulation the way an engineer thinks about a plant's distribution network. Pipes rarely fail from one dramatic event — they fail from years of pressure load, material fatigue and accumulated sediment. Your vessels carry a pressure pulse with every heartbeat, for decades, and vascular age measures how well that network is holding up.

How much does vascular age count toward my Longevity Score?

The vascular dial carries 18% of the composite Longevity Score, scored from 4 biomarkers against longevity-optimised ranges rather than standard clinical cut-offs.

What is the practical rule for improving vascular age?

Steer with blood pressure trends and the inputs you control. Audit with stiffness and plaque imaging when they are genuinely indicated.
