Indian Heart Age — 6 Markers’ Framework

Written by Editorial Team

October 5, 2026

Your chronological age tells you how many years you have lived.
Your heart age asks a different question: how old does your cardiovascular risk profile behave?

Two Indians of the same age can have dramatically different cardiovascular risk.

A 42-year-old with a healthy waist, normal blood pressure, favourable ApoB, good glucose control, adequate physical activity and no smoking exposure may have a substantially healthier cardiovascular profile than another 42-year-old with abdominal obesity, hypertension, insulin resistance and elevated atherogenic lipoproteins.

That is the thinking behind the Indian Heart Age — 6-Marker Framework.

Rather than looking at one laboratory number in isolation, the framework brings together six practical dimensions of cardiovascular health that are particularly relevant to Indian adults:

The Six Markers

Marker	What it tells us	Why it matters
1. Waist Circumference	Visceral/adipose risk	Indians can develop metabolic risk at relatively lower BMI
2. Blood Pressure	Vascular pressure load	Persistent hypertension accelerates cardiovascular risk
3. ApoB / Atherogenic Lipoproteins	Number of cholesterol-containing particles	Helps quantify atherogenic particle burden
4. HbA1c / Glucose Status	Long-term glycaemic exposure	Detects diabetes and prediabetes risk
5. Triglycerides / HDL-C Pattern	Metabolic health	Often reflects insulin resistance and cardiometabolic risk
6. Physical Activity / Cardiorespiratory Fitness	Functional cardiovascular reserve	Fitness strongly influences long-term cardiovascular health

Together, these six markers create a more complete picture than any single “cholesterol number.”

Proposed structure

Domain	Points	What it represents
Waist circumference	0–20	Central adiposity
ApoB	0–25	Atherogenic particle burden
Lp(a)	0–15	Inherited risk
Blood pressure	0–15	Vascular pressure load
HbA1c	0–15	Glycaemic/metabolic stress
TG/HDL-C	0–10	Insulin-resistant lipid phenotype
TOTAL	100	Composite screening score

Proposed interpretation

Score	Indian Heart Age interpretation
0–19	🟢 Lower-risk phenotype
20–39	🟢 Mild early-risk signals
40–59	🟡 Metabolic/atherogenic warning
60–74	🟠 High-risk phenotype
≥75	🔴 Very high-risk phenotype — clinical assessment recommended

Important: these score bands are proposed design parameters, not validated clinical thresholds.

Check Your Risk Score for Heart Health

1. WAIST — 20 points

Men

Waist	Points
<78 cm	0
78–84.9	5
85–89.9	10
90–99.9	15
≥100	20

Women

Waist	Points
<72 cm	0
72–79.9	5
80–89.9	15
≥90	20

This deliberately uses Indian-specific thresholds rather than Western BMI/waist assumptions.

2. ApoB — 25 points

For the screening algorithm, I would avoid simply copying treatment targets. A preliminary scoring architecture could be:

ApoB	Points
<80 mg/dL	0
80–99	5
100–119	10
120–139	15
140–159	20
≥160	25

This makes ApoB the largest component because it directly represents atherogenic particle number and has particularly compelling relevance to South Asian risk.

3. Lp(a) — 15 points

This should be treated differently.

Lp(a)	Points
<30 mg/dL	0
30–49	5
50–74	10
≥75	15

4. Blood Pressure — 15 points

Use the average of properly measured readings, rather than a single casual reading.

BP phenotype	Points
<120/<80	0
120–129 / <80	3
130–139 or 80–89	7
140–159 or 90–99	12
≥160 or ≥100	15

A confirmed diagnosis of hypertension should trigger clinical management rather than simply increasing the score.

5. HbA1c — 15 points

HbA1c	Points
<5.7%	0
5.7–6.0%	5
6.1–6.4%	10
≥6.5%	15

Again, ≥6.5% should not simply be treated as “15 points.”

It should trigger the message: “This result may indicate diabetes and requires appropriate clinical confirmation/assessment.” Our Algorithm should never encourage someone to treat a potentially diagnostic result as merely a wellness score.

6. TG/HDL-C — 10 points

Because Indian/South Asian research has specifically examined this ratio, it makes sense as the final metabolic component.

Men

TG/HDL-C	Points
<2.0	0
2.0–2.9	2
3.0–3.4	5
3.5–4.9	8
≥5.0	10

Women

TG/HDL-C	Points
<1.5	0
1.5–1.9	2
2.0–2.4	5
2.5–3.9	8
≥4.0	10

The 3.5/2.5 thresholds have published South Asian data behind them.

THE REALLY INTERESTING PART: HEART AGE

Report: Your Indian Heart Score: 62/100

and: Risk phenotype: High

Then identify the drivers:

Your top 3 modifiable signals

ApoB — 128 mg/dL
Waist — 96 cm
HbA1c — 6.1%

The Bigger Idea

India does not need to wait for a heart attack to start measuring cardiovascular health.

Heart health begins years before the first cardiac event. The Indian Heart Age framework shifts the conversation from:

Disease → Treatment

toward: Measurement → Early Risk → Prevention → Better Trajectory

Because the objective is not merely to live longer. It is to keep your cardiovascular system younger for longer.
