Cardiovascular Diseases

Cardiovascular diseases remain the leading cause of death globally, claiming millions of lives each year through conditions including ischemic heart disease, stroke, and hypertensive heart disease. The burden of cardiovascular mortality varies dramatically by country and region, with higher rates observed in Eastern Europe and Central Asia due to lifestyle factors, healthcare access, and dietary patterns.

Cardiovascular diseases (CVDs) are the leading cause of death globally, claiming an estimated 17.9 million lives each year — roughly 32% of all deaths worldwide. The category encompasses ischaemic heart disease, stroke, heart failure, peripheral arterial disease, rheumatic heart disease, and cardiomyopathies. Atherosclerosis — the progressive build-up of lipid-laden plaques in arterial walls — underlies most ischaemic events. Key modifiable risk factors include hypertension, dyslipidaemia, diabetes, tobacco use, physical inactivity, and unhealthy diet. While age-standardised CVD mortality has declined substantially in high-income countries since the 1970s thanks to improved prevention, diagnostics, and acute care, rates remain stubbornly high across South Asia, Eastern Europe, and Central Asia. The epidemiological transition in low- and middle-income countries — where urbanisation, dietary shifts, and tobacco uptake are accelerating — means that four out of five CVD deaths now occur outside high-income settings. Addressing this burden requires population-level strategies for blood pressure control, tobacco cessation, and salt reduction alongside health-system strengthening.

Across 210 countries, cardiovascular diseases accounts for an average of 30.0% of total deaths. Regional disparities are substantial: Europe & Central Asia has the highest regional average at 39.5%, while Sub-Saharan Africa records the lowest at 15.6% — a 2.5-fold difference that underscores the geographic inequality in cardiovascular diseases mortality burden.

CVD prevention operates at population and individual levels. Population measures include tobacco taxation, trans-fat bans, salt-reduction policies, and urban design promoting physical activity. At the individual level, blood pressure management remains the single most impactful intervention: treating hypertension alone could prevent millions of strokes and heart attacks annually. Statin therapy for elevated LDL cholesterol, aspirin for secondary prevention, and glycaemic control in diabetics form the pillars of pharmacological prevention. The WHO HEARTS technical package provides a practical roadmap for integrating CVD management into primary care in resource-limited settings. Early detection through routine screening and affordable polypill strategies show promise for closing coverage gaps.
