What is the #1 leading health problem?
Short answer: The #1 leading health problem worldwide, measured by deaths, is ischemic heart disease (coronary artery disease). It is the top cause of mortality and a major contributor to disability, driven mainly by cardiovascular risk factors.
Explanation
Ischemic heart disease (IHD) — caused by reduced blood flow to the heart from atherosclerosis of coronary arteries — has been the single largest cause of death globally for decades according to WHO and global burden of disease data. IHD is part of the broader category of cardiovascular disease, which along with other noncommunicable diseases accounts for the majority of deaths in most countries. Major modifiable risk factors include high blood pressure, tobacco use, high blood glucose (diabetes), high cholesterol, unhealthy diet, physical inactivity and harmful alcohol use. Early detection and management of these risks significantly reduce IHD incidence and mortality.
