Why Heart Disease Reaches South Asians a Decade Earlier

Heart disease reaches South Asians earlier and more often than most other populations, a pattern the American Heart Association has set out in a dedicated scientific statement. The reasons include central obesity, diabetes, tobacco including naswar, and late check-ups. The answer is screening years before symptoms arrive.

Why does heart disease start earlier in South Asians?

South Asians, meaning Pakistanis, Indians, Bangladeshis and their relatives abroad, develop heart artery disease more often and at younger ages than many other groups. The American Heart Association has published a scientific statement on cardiovascular disease in South Asians describing exactly this, and European Society of Cardiology prevention guidelines treat South Asian background as a factor that raises a person's calculated risk.

Why it happens is a combination rather than a single cause. Part of it looks inherited: the way South Asian bodies store fat and handle sugar and cholesterol works against the heart. Sitting on top of that are the risk factors that are everywhere in Pakistan: diabetes, high blood pressure, tobacco in several forms, fried and sugary food, very little daily exercise, and a habit of seeing a doctor only once something hurts.

The practical meaning is uncomfortable. A Pakistani man in his forties can be carrying the artery disease of a European man in his fifties. Waiting for the heart-check age that Western habits suggest means starting a decade late. The rest of this guide covers the risk factors you can actually do something about, and when to get screened.

What is central obesity and why is it so dangerous?

Central obesity means fat stored around the waist and the internal organs rather than spread across the body. It matters because this deep belly fat is chemically active and interferes with how the body handles sugar and cholesterol, and South Asians tend to store fat this way even at a normal body weight.

Which is why the bathroom scale misleads so many people here. A man can weigh exactly what the charts call normal, look slim in a shalwar kameez, and still carry a waistline quietly driving him toward diabetes and heart disease. Thin outside, fat inside is the pattern we see week after week in clinic. The waist tells the truth the scale is hiding. If your waistband has needed loosening year after year, your heart risk has been climbing with it.

The fix is unglamorous, which is probably why it gets ignored: daily brisk walking, smaller portions of rice and roti, fewer fried snacks and sugary drinks, and patience. Belly fat responds to steady habits over months. It does not respond to a crash diet over a fortnight.

How much does diabetes raise the risk of an early heart attack?

Diabetes raises heart risk sharply, and it is one of the main reasons Pakistani hearts fail early. High blood sugar damages the lining of the blood vessels, speeds up the formation of blockages in the heart arteries, and usually travels in company with high blood pressure and abnormal cholesterol. That package multiplies the danger rather than adding to it.

Two features make diabetes especially treacherous. It is silent, so many Pakistanis carry raised sugar for years before anyone finds it, often only after a complication has already arrived. And it dulls the nerves that carry pain, so a diabetic's heart attack may announce itself with breathlessness or weakness instead of classic chest pain, and get missed. Our heart attack page describes that pattern in more detail.

If you have never had a fasting blood sugar or an HbA1c test as an adult, that one test is among the most valuable you can get. If you already have diabetes, controlling it is heart treatment as much as sugar treatment, and your heart risk deserves formal assessment even when you feel entirely well.

Do cigarettes, naswar and hookah all harm the heart?

Yes, every one of them. Cigarettes, naswar, gutka, paan with tobacco and hookah all deliver nicotine and harmful chemicals that raise blood pressure, damage the lining of the vessels and make the blood clot more readily. There is no form of tobacco the heart tolerates safely.

Two local myths deserve a direct answer. The first is that naswar is safer because it never touches the lungs. The harmful substances are absorbed through the mouth into the same bloodstream and reach the same heart arteries. The second is that hookah is just flavoured water vapour. A hookah session delivers a large volume of smoke, and because it is social and unhurried, people consume more rather than less.

The reward for quitting is real and it starts fast: blood pressure and circulation begin improving within days to weeks, and heart risk keeps falling the longer you stay off it. For a tobacco user with an early-risk heart, quitting outperforms every supplement, tonic and herbal remedy sold for the purpose, and it is not close.

Which everyday habits add to the risk?

The ordinary routines of Pakistani life, generous oil and ghee, deep-fried snacks, mithai at every celebration, sweet chai several times a day, and very little walking, each give a small push in the wrong direction. Together they add up to an early start for heart disease.

You do not need a foreign diet to fix this. You need a gentler version of your own:

• Cook with less oil, and reuse it less. Repeatedly reheated frying oil is worse than fresh. Measure oil into the pot instead of pouring freely.
• Shrink the fried and sweet extras. Samosay, pakoray, mithai and bakery items belong to occasions, not to Tuesday.
• Watch the sugar you drink. Soft drinks, packaged juices and heavily sugared chai are sugar you never chew and never notice.
• Walk daily. A brisk 30 to 40 minute walk most days is realistic in Abbottabad's climate and costs nothing. Movement improves sugar, pressure, weight and mood at the same time.
• Guard your sleep and your stress. Chronically short sleep and constant stress both push blood pressure upward.

High cholesterol deserves its own mention because it is common, partly inherited, and completely silent. A slim young person can have it. Our high cholesterol page explains what the lipid profile numbers mean and how the condition is treated.

When should Pakistanis start heart screening?

Earlier than Western defaults, because the disease starts earlier. A sensible pattern for Pakistani adults is to know four numbers from young adulthood: blood pressure, fasting blood sugar, cholesterol, and waist size, rechecked at whatever interval your doctor sets based on the results.

Screening should start earlier still, in the twenties or early thirties, for anyone with a parent or sibling who had an early heart attack, or with diabetes, high blood pressure, kidney disease, tobacco use or a waistline that keeps growing. None of these tests is complicated. They are a blood pressure cuff, some simple blood tests and a measuring tape, followed by an honest conversation.

A structured preventive cardiology and risk assessment visit puts the pieces together, your history, family history, examination and results, into an overall risk picture, then turns that into a concrete plan: what to change, whether any medicine is justified, and when to recheck. Dr. Muhammad Ali Khan, Consultant Cardiologist, provides this assessment at clinics in Abbottabad, and the difference between the families who come early and the ones who come after the first heart attack is visible every week.

What can you do about it starting this week?

Start with the parts that need no test results: walk daily, cut the fried snacks and sugary drinks, take the salt shaker off the table, and if you use any tobacco, set a quit date. Then book the screening that gives you your real numbers, because guessing protects nobody.

If the numbers come back normal, you have earned genuine peace of mind and a baseline to compare against in ten years. If something is raised, you have found it years before it could close an artery, which is the entire point of screening in a population where hearts fail early. A clinic consultation costs Rs. 2,000 and an online video consultation costs Rs. 2,500, and you can book either through our appointments page.

One boundary to keep clear. This guide is about preventing an emergency, not managing one. If you or someone in your family has chest pressure, a cold sweat or sudden breathlessness right now, call 1122 or go straight to DHQ Hospital Abbottabad Emergency.
