Researchers at The George Institute for Global Health have unveiled the world’s first Blood Pressure Treatment Efficacy Calculator—a tool which simply works like “Google Maps for BP treatment.”

Just as Google Maps suggests the best route using data from millions of journeys, this calculator predicts how much different medicines—or combinations—are likely to lower blood pressure.

The calcualtor is based on data from nearly 500 randomised clinical trials involving over 100,000 people.

The calculator classifies drugs into low, medium, and high intensity, similar to the gear system in a car—helping doctors select the right “gear” to bring BP down efficiently.

High blood pressure is a silent killer. It affects 1.3 billion people worldwide and causes around 10 million deaths annually.

Scientists believe this innovation could mark a turning point in the battle against one of the world’s deadliest but most preventable conditions.
