Heart disease is the biggest killer on Earth, and almost nobody is afraid of it. It doesn’t crack the Chapman Survey of American Fears top tier, it doesn’t feature in disaster movies, and most adults file it somewhere between "a problem for old people" and "a problem for people who don’t look after themselves". The intuitive mental model is that heart attacks are something that happens to someone else’s uncle in his seventies, which gets the age-weighting roughly right and the cumulative lifetime frequency badly wrong. Risk-literacy studies consistently find that people underestimate their lifetime cardiovascular mortality risk relative to vivid-but-rare causes such as terrorism, plane crashes, or shark attacks.

Show derivation
Uses WHO’s 2024 Top 10 Causes of Death update, which identifies ischaemic heart disease as the world’s biggest killer at 13% of global deaths in 2021 — roughly 9.1 million deaths per year out of ~68 million total deaths. Across a global adult population of ~6.0 billion (age 18+), that is an annual rate of ~1.52 per 1,000 adults per year. Compounded over 60 years of remaining adult life: 1 − (1 − 0.00152)^60 ≈ 0.087, rounded to 0.085 to account for competing mortality (an adult who dies of cancer at 65 never gets the chance to die of heart disease at 82) and for the fact that a non-trivial share of ischaemic heart disease deaths occur above age 85 where many readers will already have been removed from the denominator by other causes. Note that this is the narrower "ischaemic heart disease" figure, not the broader "cardiovascular disease" aggregate (which includes stroke and hypertensive heart disease and totals ~19.8 million deaths per year per WHO, or roughly 32% of global mortality). Stroke is covered in a separate Likelier entry; this number is specifically heart. Scope is global-adult-lifetime rather than US-adult-lifetime because CVD mortality rates vary by roughly an order of magnitude between regions, and a US-only headline would understate the global baseline and obscure the regional variance shown in the breakdown below.

This entry reports ischaemic heart disease mortality only, not the broader cardiovascular disease (CVD) aggregate. The WHO CVD fact sheet puts total CVD deaths at ~19.8 million per year (≈32% of global mortality); adding stroke, hypertensive heart disease, rheumatic heart disease, and the other CVD subtypes would roughly double the headline number and push the lifetime global adult figure closer to 1 in 6. Stroke is covered in its own Likelier entry, which is why this page keeps them separate. The personal_factor_multipliers are illustrative relative risks from the epidemiological literature, not a calibrated personal risk calculator — the real multipliers interact (smoking and hypertension are not independent) and are strongly age-dependent. For a formal personal estimate, clinical tools such as the AHA PREVENT equations or the European SCORE2 charts are the appropriate instrument. The regional_breakdown numbers are order-of-magnitude anchors drawn from WHO / GBD age-standardised mortality rates, not exact lifetime probabilities for any individual.
Regional breakdown
The headline figure averages across very different populations. Here’s how the probability varies by geography or context:
| Region / context | Lifetime probability | Notes |
|---|---|---|
| Global average | 1 in 12 |
WHO 2021 ischaemic heart disease mortality, compounded over 60 adult years |
| Eastern Europe / Central Asia | 1 in 4.0 |
Highest CVD mortality rates globally; Russia, Ukraine, Belarus, Kazakhstan dominate |
| United States | 1 in 9.1 |
Above global average; rates have been falling since ~1970 but plateaued recently |
| East Asia (Japan, South Korea) | 1 in 33 |
Low CVD mortality despite industrialisation — diet, blood pressure control, genetics |
Risks at similar odds

Heart disease is the biggest killer on the planet and almost nobody lists it as a fear. The World Health Organization’s 2024 Top 10 Causes of Death update puts ischaemic heart disease at the top, responsible for 13% of all deaths worldwide — about 9.1 million deaths per year in 2021, and the single cause that has grown the most in absolute terms since 2000. Spread across a global adult population of roughly six billion and compounded over a normal 60-year adult lifespan, that works out to a lifetime mortality figure of about 1 in 12 for a generic adult alive today. For scale: that is roughly 7,000 times the lifetime odds of dying in a plane crash for a regular flyer, and about 8 times the lifetime odds of dying in a car crash. Broaden the lens from “heart” to the full cardiovascular disease aggregate and the WHO CVD fact sheet reports 19.8 million annual deaths — roughly one in every three deaths on Earth.
The interesting thing about heart disease is how reliably it gets underweighted in fear surveys. People imagine plane crashes, sharks, and strangers in parking lots in vivid detail; nobody imagines a heart attack. Classic availability bias: the risk is slow, non-vivid, statistically distributed across decades, and associated with ordinary life rather than with a discrete dreaded event. The Chapman Survey of American Fears finds Americans ranking terrorism, corrupt government officials, and loved ones dying above heart disease — even though heart disease will, in the end, kill more of them than essentially every other entry on this site combined. This is why Likelier tags the entry underrated: the perceived/actual gap runs the opposite way from planes or sharks.
Where the headline number doesn’t apply: almost everywhere, because heterogeneity on this fear is enormous. Age-standardised cardiovascular mortality in parts of Eastern Europe and Central Asia runs roughly ten times higher than in Japan or South Korea, a gap that has more to do with diet, blood pressure control, and smoking prevalence than with genetics. Within any given country, the gap between an adult who smokes, has untreated hypertension, and carries a family history of early CHD, and one who doesn’t smoke, controls blood pressure, and eats a broadly Mediterranean diet, is larger than the gap between most pairs of fears in the Likelier catalogue. Heart disease is probably the single most modifiable major cause of death on the site — which is also part of why the global aggregate is more a ceiling than a forecast for any particular reader.

1 in 5 adults will experience major depression. 1 in 12 will die of heart disease. Depression is nearly twice as common, but heart disease gets the awareness campaigns, red ribbons, and workplace AED stations.
Dying of heart disease is roughly 9,700× more likely than dying in a mass shooting over a US adult lifetime (1 in 12 vs ~1 in 110,000). Public coverage runs the inverse ratio.

Ischaemic heart disease is the world's biggest killer, responsible for 13% of global deaths (~9.1 million) in 2021- Excerpt
“"The world's biggest killer is ischaemic heart disease, responsible for 13% of the world's total deaths. [...] rising by 2.7 million to 9.1 million deaths in 2021. [...] The top global causes of death, in order of total number of lives lost, are associated with two broad topics: cardiovascular (ischaemic heart disease, stroke) and respiratory (COVID-19, chronic obstructive pulmonary disease, lower respiratory infections)." ”

- 9.1 million deaths/year divided by ~6.0 billion adults (age 18+) = 1.52 per 1,000 adults/year. Compounded over 60 adult years: 1 − (1 − 1.52e-3)^60 ≈ 0.087, adjusted to 0.085 for competing mortality. WHO notes ischaemic heart disease has shown "the largest increase in deaths" of any leading cause since 2000, driven primarily by population growth and ageing rather than rising age-standardised per-capita risk.

An estimated 19.8 million people died from CVDs in 2022 (~32% of global deaths); 85% of those deaths from heart attack and stroke; >75% occur in low- and middle-income countries- Excerpt
“"An estimated 19.8 million people died from CVDs in 2022, representing approximately 32% of all global deaths. Of these deaths, 85% were due to heart attack and stroke. [...] Over three quarters of CVD deaths take place in low- and middle-income countries." ”

- Used as the upstream scale check and to justify the regional_breakdown entries. The 19.8M CVD aggregate minus ~6.8M stroke deaths (per WHO top-10 / WSO) leaves roughly 13M deaths from heart disease and other non-stroke CVD, consistent with the 9.1M ischaemic-heart-disease-only figure once hypertensive heart disease, rheumatic heart disease, and cardiomyopathies are added. Used as authoritative cross-check on geographic concentration: >75% of CVD deaths in LMICs drives the East Asia vs Eastern Europe vs US spread in the regional_breakdown.

- ~371,500 US coronary heart disease deaths / ~260 million US adults ≈ 1.43 per 1,000 adults/year. Compounded over 60 adult years: 1 − (1 − 1.43e-3)^60 ≈ 0.082. Adding hypertensive and other ischaemic forms brings the US narrow-heart-disease lifetime figure to roughly 0.10-0.12, which is what the regional_breakdown uses for the US entry. The figure is slightly lower than the global adult headline because US crude rates are below the Eastern European / Central Asian peak but well above the East Asian low, so the US sits modestly above the global average once you restrict to ischaemic-heart-disease mortality. Used as an anchor for the US-specific row and for the personal-factor multipliers, which are based on well-established relative risks from Framingham-derived cohorts and subsequent cardiovascular epidemiology.
