How To Keep Your Heart Healthy

Heart disease is the leading cause of death in India — but it is also one of the most preventable. The choices you make every day — what you eat, how much you move, whether you smoke, how you manage stress — have a profound impact on your cardiovascular health. And understanding your genetic cardiovascular risk profile allows you to make those choices with precision, targeting the interventions most likely to benefit your specific biology.

1. Know Your Numbers

You can't manage what you don't measure. Key cardiovascular health numbers everyone should know:

• Blood pressure: Target below 120/80 mmHg (optimal); below 130/80 mmHg (acceptable). Hypertension is the single most important modifiable cardiovascular risk factor.
• LDL cholesterol: Target below 100 mg/dL for most people; below 70 mg/dL for high-risk individuals. LDL is the primary driver of atherosclerosis.
• Fasting glucose and HbA1c: Diabetes doubles or triples cardiovascular risk. Fasting glucose below 100 mg/dL and HbA1c below 5.7% are normal.
• Lp(a): A genetically determined lipoprotein that significantly increases cardiovascular risk. Particularly important for Indians, who have among the highest Lp(a) levels globally. Not included in standard lipid panels — ask your doctor to test it.
• BMI and waist circumference: Abdominal obesity (waist >90 cm in men, >80 cm in women for Indians) is a major cardiovascular risk factor.

2. Eat a Heart-Healthy Diet

The Mediterranean dietary pattern — rich in vegetables, fruits, whole grains, legumes, nuts, olive oil, and fish — is the most evidence-based dietary approach for cardiovascular health. Key principles:

• Minimize refined carbohydrates and added sugars
• Replace saturated fats (ghee, butter, coconut oil) with unsaturated fats (olive oil, mustard oil, nuts)
• Eat fatty fish (salmon, mackerel, sardines) 2–3 times per week for omega-3s
• Increase dietary fiber from vegetables, legumes, and whole grains
• Minimize processed and ultra-processed foods
• Limit sodium to reduce blood pressure

3. Exercise Regularly

Physical activity is one of the most powerful cardiovascular medicines available. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week (brisk walking, cycling, swimming) plus 2 sessions of resistance training. Even 30 minutes of brisk walking daily significantly reduces cardiovascular risk.

4. Don't Smoke

Smoking is the most powerful modifiable cardiovascular risk factor. It doubles the risk of heart attack and significantly increases stroke risk. Quitting smoking at any age provides cardiovascular benefit — within a year of quitting, heart attack risk is halved.

5. Manage Stress

Chronic psychological stress elevates cortisol, increases blood pressure, promotes inflammation, and drives unhealthy behaviors (overeating, smoking, alcohol use). Mindfulness, yoga, adequate sleep, and social connection are evidence-based stress management strategies with cardiovascular benefits.

6. Know Your Genetic Cardiovascular Risk

Genetics accounts for a significant proportion of cardiovascular disease risk. Variants influencing Lp(a) levels, LDL metabolism, blood pressure regulation, and inflammatory response can dramatically increase risk — even in people with otherwise healthy lifestyles. Understanding your genetic cardiovascular risk profile allows you to target preventive interventions where they will have the greatest impact.

FAQs

At what age should I start worrying about heart health?

Cardiovascular risk factor management should begin in early adulthood. Atherosclerosis begins in the 20s and 30s — the earlier you establish heart-healthy habits, the more you protect your future cardiovascular health. For those with family history or genetic risk factors, proactive management from an early age is particularly important.
