How to Keep Your Heart Younger: Evidence-Based Heart Health Guide for Indians

Why this matters for Indians

South Asians often develop heart disease earlier, and many heart attacks happen in people whose “cholesterol looked fine”. That is partly because old LDL “normal” ranges were too relaxed for high-risk people, and partly because other risk factors — diabetes, BP, smoking, belly fat, low activity — were not controlled. Genetics matters (for example, Lp(a) and family history), but most risk is modifiable.

Life’s Essential 8 — your heart checklist

Behaviours	Health factors
Eat better	Healthy weight (watch waist)
Be more active	Control non-HDL/LDL cholesterol
No tobacco (including vaping, gutkha)	Healthy blood sugar
Healthy sleep (7–9 hours)	Healthy blood pressure

Source: AHA Life’s Essential 8 (2022). People with higher scores have much lower rates of heart disease in long-term studies.

Know your numbers

Measure	Target (most adults)
Blood pressure	Below 120/80 is ideal; 130/80 or higher needs attention
LDL cholesterol	Below 100 mg/dL (below 70 or 55 if high risk — CSI 2024)
Triglycerides	Below 150 mg/dL
Fasting glucose / HbA1c	Below 100 mg/dL / below 5.7%
Waist	Men below 90 cm, women below 80 cm; waist less than half your height

Useful extra tests — for the right person

• Lp(a): once in a lifetime (CSI 2024), especially with early heart disease in the family.
• ApoB: helpful when triglycerides are high or with diabetes/obesity.
• hs-CRP: can refine risk in borderline cases; test when well.
• ECG, echo, stress tests, CT calcium score: for symptoms or specific risk situations as advised by a doctor — not routine for low-risk people without symptoms (USPSTF).

See my ApoB and LDL guide for details.

Move: cardio + strength

In a randomised trial, 2 years of structured exercise in sedentary adults aged 45–64 improved fitness (VO₂ max) by about 18% and made the heart less stiff (Howden et al., 2018). The programme built up to 4–5 sessions a week, including one high-intensity session, plus strength work.

• 150–300 minutes a week of moderate activity (brisk walking, cycling) or 75–150 minutes vigorous (WHO 2020)
• Strength training 2–3 times a week
• Walk after meals; break up long sitting
• Start gently and build up; get medical clearance first if you have heart disease or symptoms

Eat for your heart

• A Mediterranean-style pattern — vegetables, fruits, whole grains, dals, nuts and unsaturated oils — reduced major cardiovascular events by about 30% in the PREDIMED trial (2018). The Indian version: sabzi, dal, whole grains, curd, nuts, fish if you eat it.
• Replace saturated fat (excess ghee, butter, fatty meat) with unsaturated oils (AHA 2017). Ghee is fine in small amounts — it is not a “heart-healthy oil”.
• Cut salt, packaged snacks, sugary drinks and deep-fried food.
• Fatty fish 2 times a week, or flax/walnuts if vegetarian.
• Foods rich in dietary nitrate (beetroot, leafy greens) may modestly lower BP.

Sleep, stress and people

• Sleep 7–9 hours — poor sleep is linked with higher BP, sugar and weight.
• Chronic stress raises BP and heart rate; slow breathing, activity and support help.
• Loneliness and social isolation are linked to about 29% higher heart disease and 32% higher stroke risk (Valtorta et al., 2016). Stay connected.

Tobacco and alcohol

• Stopping smoking cuts heart attack risk sharply — the benefit begins within a year and keeps growing over time.
• Chewing tobacco, gutkha and vaping are not safe alternatives.
• Alcohol raises BP and triglycerides; there is no need to start drinking for “heart health”.

What about pollution, microplastics and “toxins”?

Air pollution is a real heart risk, especially in Indian cities — use masks on high-pollution days, avoid exercising next to heavy traffic, and ventilate kitchens. Claims about microplastics, EMF or “filtered water” preventing heart attacks are not proven. Focus first on the big eight.

Key takeaways

1. Most heart risk is modifiable — follow Life’s Essential 8.
2. Know your BP, LDL, sugar, triglycerides and waist.
3. Lp(a) once; other advanced tests only when useful.
4. Cardio + strength, a plant-rich diet, sleep and connection protect the heart.
5. No tobacco in any form; don’t drink for “heart health”.
