Heart disease in India has risen almost threefold over the last seven years, and the damage is now showing up earlier than ever. According to the latest survey by the National Statistical Organisation (NSO), even young people aged 15 to 29 are vulnerable. In clinics across the country, arteries are being found narrowed in people in their early thirties. However, the concern goes beyond the heart. Heart disease and brain disease are usually treated as two separate conversations, but they share the same blood vessels. The arteries feeding the heart and those feeding the brain are part of one network, exposed to the same pressures, the same inflammation and the same slow damage. When arteries narrow in the heart of someone in their thirties, the same process is quietly under way in the vessels supplying the brain. It is simply less visible until something goes wrong.
A heart attack announces itself through chest pain, sweating and breathlessness. Damage to the brain’s blood supply rarely arrives so dramatically. It often begins as brain fog, poor concentration or a fatigue that no amount of weekend rest seems to fix.
Young professionals who visit clinics with these complaints have usually explained them away as burnout or stress. It is an understandable conclusion. We live in demanding times, and tiredness has become so routine that few people question it. But stress is only one part of the picture. Poor sleep and sedentary habits also have a silent impact on the brain’s blood supply, one that builds up quietly over years without any visible symptom. There is no alarm, only a gradual erosion that is noticed too late.
This link is changing how we practise. Patients who come in with cognitive complaints are increasingly asked about their cardiac history, because the two conditions are far more connected than people realise. Chronic stress, disrupted sleep and high blood pressure do not only strain the heart. They strain the brain’s blood supply in the same way. A vessel under pressure does not care which organ it serves.
By the time someone has a cardiac event, the brain has in many cases already lived with reduced blood flow for years. That is what makes early detection so important. The window for prevention is wide open, but too many people are walking past it.
The NSO findings released earlier this year that people between 15 and 29 are at risk deserve particular attention. These are students and first-time employees who assume they have decades of good health ahead of them and who are the least likely to seek a check-up for vague symptoms. Believing that heart and brain problems belong to old age is the most dangerous assumption a young person can make today.
The response does not need to be complicated. If you are struggling with concentration, feel constantly drained despite doing nothing unusual, or have had poor sleep for months, do not dismiss it as the price of a busy life. Start by getting your blood pressure checked regularly, and have your cholesterol and blood sugar levels tested. Make time to move every day, even if it is only a brisk walk, and protect your sleep as seriously as you protect your work deadlines.
These are ordinary, unglamorous habits, but they keep blood flowing freely to both the heart and the brain. The two are not separate conversations. Look after one, and you are looking after the other.
