Heart disease often starts earlier in Indians. Learn the risk factors, who should consider a calcium score or CT coronary angiography and what prevention works.
Indians tend to develop heart disease about 5 to 10 years earlier than people in many other regions, often with narrow arteries, central obesity, diabetes and low HDL cholesterol. A calcium score or CT coronary angiography may help people with a family history, diabetes or symptoms, but lifestyle and risk factor control matter most.
Why Heart Disease Appears Earlier
Studies show that South Asians have more visceral fat, higher insulin resistance, higher triglycerides, smaller cholesterol particles and more inherited risk such as Lp(a). Traditional diets high in refined carbohydrates and fried foods, low physical activity, stress, air pollution and tobacco add to the risk. See heart attack warning signs.
Risk factorWhy it matters in IndiansCentral (belly) obesityHigh risk even at a normal weightDiabetes and insulin resistanceVery common and starts earlyLow HDL and high triglyceridesTypical patternHigh Lp(a)Inherited and commonTobacco, including chewingStrongly raises riskFamily history before age 55 to 65Strong predictorFirst Step: Know Your Numbers
- Lipid profile including LDL, HDL and triglycerides; Lp(a) once in life
- Fasting sugar and HbA1c
- Blood pressure at every visit
- Waist size: concern above about 90 cm in men and 80 cm in women
- Family history of heart disease before 55 in men or 65 in women
Who Should Consider a Scan?
A calcium score may help people aged about 35 to 40 and above with borderline or intermediate risk, a strong family history or unclear treatment decisions. CT coronary angiography is for chest pain, breathlessness or abnormal stress tests. Not everyone needs a scan. See coronary calcium score and CTCA with a family history.
Prevention That Works
- 150 minutes of brisk activity weekly, plus strength training
- More vegetables, pulses, nuts, fruits and whole grains; less refined flour, sugar and fried food
- Quit tobacco in all forms
- Keep waist size and weight in range
- Statins and other medicines when advised
- Good sleep and stress control
Special Groups
People with diabetes, chronic kidney disease, early menopause and polycystic ovary syndrome have higher risk. Women are often under-investigated, since symptoms can be atypical. Young people with very high LDL may have familial hypercholesterolaemia and need early treatment. See CTCA in women.
A Practical Example
Rohit, 38, a software engineer, has a waist of 100 cm, borderline sugar, low HDL and a father who had a heart attack at 52. His calcium score is 40, showing early plaque. His doctor starts diet and exercise changes, a statin and sugar control. A year later, his waist, sugar and cholesterol are better, and his risk has fallen.
After the Scan and Next Steps
Discuss your risk with a physician or cardiologist and ask for a written plan with targets for LDL cholesterol, blood pressure, sugar and weight. Repeat blood tests as advised and review your plan yearly. Teach family members to learn the warning signs of a heart attack, because early action saves lives.
Questions to Ask Your Doctor
- What is my overall 10-year and lifetime heart risk?
- Would a calcium score change my treatment?
- Do I need Lp(a) and HbA1c tests?
- Which lifestyle change should I start first?
Common Mistakes to Avoid
- Ignoring waist size because the weight looks normal.
- Skipping medicines once numbers improve.
- Waiting for symptoms before checking risk.
Booking, Timing and Report
Book a morning slot if possible, since fasting is easier. Carry your doctor's prescription, previous heart and blood reports, a recent creatinine report and a medicine list. Allow 45 to 90 minutes at the centre. Reports are usually ready within 24 to 48 hours, because vessel images need careful review.
Key Facts at a Glance
- Indians often develop heart disease earlier
- Belly fat, diabetes, low HDL and Lp(a) are key risks
- A calcium score helps selected people
- Lifestyle and early treatment matter most
Ask your doctor for a yearly check-up plan with a written list of targets for sugar, blood pressure, cholesterol and waist size.
