The #1 disease globally, by leading cause of death, is Cardiovascular Diseases (CVDs), encompassing heart attacks and strokes, responsible for about one-third of all deaths, with Ischemic Heart Disease being the top killer within that group, followed by other non-communicable diseases like cancers and respiratory illnesses. While infectious diseases like TB are major killers, CVDs consistently top the list for overall mortality, especially in middle-income countries.
Leading Causes of Death
The number one killer in the world is cardiovascular disease (CVD), including heart disease and stroke, responsible for about one-third of all global deaths, claiming nearly 18-20 million lives annually, and remains the leading cause across all regions, according to WHO and World Heart Federation. While COVID-19 caused significant deaths in recent years, CVD has consistently held the top spot for decades, with increases seen globally, especially in younger populations.
Globally, Ischaemic Heart Disease (Coronary Artery Disease) is the number one cause of death, responsible for a significant portion of deaths, with cardiovascular diseases (CVDs) as the leading overall killer, followed by cancer, according to the World Health Organization (WHO).
