Brunei Launches AI Heart Disease Prevention Program

A tiny nation is making a giant leap in preventing the world's deadliest health threat.

Brunei announced at the World Economic Forum in Davos this week that it will use artificial intelligence to identify citizens at risk for heart disease before symptoms even appear. The program, called CARDIO4Cities, partners the country's Ministry of Health with the Novartis Foundation and EVYD Technology to screen the entire population and deliver personalized prevention plans.

Cardiovascular disease kills more people globally than any other cause, accounting for over 70% of deaths worldwide. In Brunei, heart disease is also the leading killer, creating enormous pressure on hospitals and families.

The new system works through BruHealth, Brunei's national health app that already reaches 85% of the population. Originally built to track COVID-19, the platform has transformed into a complete digital health system where residents can access their medical records, get AI-powered health advice, and schedule appointments.

Now, artificial intelligence will analyze population-wide health data to spot patterns that predict heart attacks and strokes years in advance. High-risk individuals will receive targeted interventions like medication, lifestyle coaching, and regular monitoring before serious problems develop.

The technology shift represents a fundamental change in how healthcare works. Instead of waiting for people to get sick, the system actively hunts for early warning signs and steps in to prevent disease.

The Ripple Effect

This isn't just a win for Brunei. The CARDIO4Cities program has already transformed health outcomes in over 40 cities worldwide, including São Paulo, Dakar, and Ulaanbaatar.

Results from those cities show blood pressure control rates improving three to six times within 15 to 21 months. Even more impressive, stroke rates dropped by 13% and heart attacks fell by 12%.

Brunei becomes the first nation to implement the program at full national scale, targeting four major risk factors: high blood pressure, diabetes, obesity, and high cholesterol. If successful, the model could be replicated in countries around the world struggling with similar health challenges.

The platform also benefits medical researchers globally by helping pharmaceutical companies identify patients for clinical trials faster, monitor data quality, and generate real-world evidence for new treatments.

Gong Yingying, founder of Yidu Tech, explained that truly resilient health systems must act before risks fully emerge. The Brunei program represents exactly that shift: from reactive response to proactive prediction, from fragmented care to integrated management.

What makes this initiative special is its completeness. Rather than a pilot program in one city, Brunei is transforming its entire public health infrastructure to embrace prevention over treatment.

A small nation is showing the world that technology can help us stay healthy, not just treat us when we're sick.
