Silent heart disease nearly claimed a banker's life—three times

Cardiovascular disease remains the world's biggest killer, claiming 19.8 million lives in 2022. The condition accounts for 85% of deaths from heart attacks and strokes alone. In low- and middle-income nations, over 14 million people died from these diseases that same year, with Egypt, Iran, and Turkey recording the highest numbers in the Middle East and North Africa region. Wali Khan, a Dubai-based investment banker, discovered his own risk after visiting a doctor for stress-relief medication. A coronary angiogram—prompted by his family history of heart disease—revealed two blocked arteries. Despite showing no symptoms, he required immediate stenting. This was not his first scare: Khan had already undergone stent procedures in 2014, 2015, and again in 2022.

Since his diagnosis, Khan has overhauled his lifestyle. He quit smoking, prioritised regular exercise, and now walks for an hour most evenings. Better sleep habits have also become part of his routine. The scale of the problem has pushed global health organisations to act. The World Heart Federation marked the 25th anniversary of World Heart Day on 29 September 2022, urging better access to high blood pressure treatment. Yet progress remains slow. Only 16 of the WHO's 193 member states have dedicated national plans for heart health.

Khan's experience highlights how early detection and lifestyle changes can help manage cardiovascular risks. Meanwhile, global data shows the urgent need for broader prevention and treatment efforts. With most deaths concentrated in poorer nations, experts stress that stronger policies and public awareness are critical to reducing the toll.
