High Blood Pressure
Deaths attributed to High Blood Pressure across countries, with trends from 1990 to 2021.

High Blood Pressure is one of the modifiable risk factors tracked by the IHME Global Burden of Disease Study. The attributable deaths shown here represent the estimated number of deaths that could be prevented if exposure to this risk factor were eliminated or reduced to optimal levels. Understanding risk factor contributions helps prioritize public health interventions and policy decisions.
Risk factor attribution uses comparative risk assessment methodology. A single death may be partially attributed to multiple risk factors, so attributable death counts should not be summed across risk factors. Data covers 204 countries from 1990 to the latest available year.
High blood pressure (hypertension) is the single largest risk factor for global mortality, contributing to an estimated 10.8 million deaths per year through ischaemic heart disease, stroke, hypertensive heart disease, and chronic kidney disease. An estimated 1.28 billion adults aged 30-79 have hypertension, of whom only 42% are diagnosed and 21% have their blood pressure controlled. Sub-Saharan Africa has the highest age-standardised prevalence globally, followed by Central and Eastern Europe. Hypertension is driven by dietary sodium excess, physical inactivity, obesity, alcohol consumption, and genetic predisposition. The condition is typically asymptomatic, earning it the label 'the silent killer.' Low- and middle-income countries bear 75% of the global hypertension burden but have the lowest rates of diagnosis, treatment, and control. Closing the treatment gap is the single highest-yield intervention available in global health.
High Blood Pressure contributes to mortality from ischaemic heart disease, stroke, hypertensive heart disease, chronic kidney disease, and 1 other conditions. The magnitude of impact varies by country depending on exposure levels, population demographics, and the availability of preventive and treatment services.
The WHO HEARTS technical package provides a simplified protocol for hypertension management in primary care. Population salt reduction through reformulation, labelling, and public awareness campaigns is highly cost-effective. Affordable generic antihypertensives (amlodipine, losartan, hydrochlorothiazide) can be delivered through task-sharing with trained community health workers. Fixed-dose combination pills (polypills) simplify treatment and improve adherence. Screening in community settings, pharmacies, and workplaces increases detection.
