Heart care shifts from surgeries to prevention, say experts

Changing the Focus of Cardiology

For decades, the gold standard in heart care has been reactive: wait for blockages, then clear them with stents or bypass surgery. That model is now being questioned by a growing number of cardiologists who argue the real battle must be fought long before a patient reaches the operating table.

Experts speaking at a recent health forum outlined a clear shift. The future, they say, is about prevention. Lifestyle changes, early detection, and better management of risk factors are being positioned as the frontline defence against India's leading cause of death.

The Alarming Rise in Younger Patients

One of the most concerning trends driving this shift is the age profile of heart patients. Doctors report seeing men and women in their 30s and 40s with advanced coronary artery disease—a condition once considered a problem for the elderly.

Sedentary jobs, high-stress lifestyles, and diets rich in processed foods are being blamed. The traditional approach of waiting for symptoms like chest pain or breathlessness often means the disease has already progressed significantly. Prevention, experts argue, must start in the workplace and the home, not the hospital.

Technology as a Preventive Tool

Wearable devices like smartwatches that track heart rate variability and detect irregular rhythms are becoming more common. Doctors see these tools as a bridge to better preventive care, allowing patients to spot anomalies early.

Artificial intelligence is also entering the picture. Algorithms can now analyse a person's medical history and lifestyle data to calculate their personalised risk of a cardiac event. This allows doctors to target interventions—diet plans, exercise regimens, or medication—at those who need them most, rather than applying a one-size-fits-all approach.

The Role of Diet and Exercise

Prevention is not a new concept, but the advice has sharpened. Cardiologists are moving beyond generic warnings about salt and fat. Specific dietary patterns, such as the Mediterranean diet rich in nuts, olive oil, and leafy greens, are being recommended based on strong evidence.

Exercise is no longer just about hitting a weekly target of minutes. The focus is on reducing prolonged sitting. Even short, frequent walks during the workday are shown to significantly lower blood pressure and improve cholesterol profiles. The message is clear: movement matters more than intensity for many patients.

What Hospitals Must Do Differently

The shift towards prevention also demands changes within the healthcare system. Hospitals are being urged to invest in wellness programmes and community outreach, not just high-tech catheterisation labs.

Several major hospital chains in India have begun offering preventive cardiology clinics. These clinics assess a patient's risk profile in detail and provide a structured plan to manage it. The model is still new, but early results show that patients who adhere to such plans have a lower rate of hospital readmissions and need fewer procedures.

Looking ahead, the integration of preventive care into standard practice will likely accelerate. As the cost of treating advanced heart disease continues to rise, both insurers and public health authorities are expected to push for policies that reward keeping people healthy, rather than just treating them when they fall ill.
