Heart Disease Still Tops the List: The 2024 US Mortality Data and What It Means for Cardiology Practice
Final federal mortality figures confirm cardiovascular disease as the nation's leading killer, even as overall death rates fall to a post-pandemic low.
The National Center for Health Statistics has released final 2024 mortality data for the United States.
A total of 3,072,666 resident deaths were registered in 2024, roughly 18,300 fewer than in 2023.
The overall age-adjusted death rate fell 3.8% year over year, and life expectancy climbed to 79.0 years, the largest single-year gain in over a decade.
Despite this broad improvement, the rank order at the top of the list did not change.
Heart disease remained the number-one cause of death for the 2024 data year, just as it has been for essentially every year since 1950.
The 2024 numbers, by the cause
Heart disease accounted for 683,491 deaths in 2024, ahead of cancer at 619,876 and unintentional injuries at 197,449.
Stroke held its position as the fourth-leading cause, contributing 166,852 deaths, with chronic lower respiratory disease and Alzheimer disease rounding out the top six.
Notably, suicide displaced COVID-19 in the top ten for the first time since 2020, as COVID-19 deaths fell 37% year over year to 31,426.

Two decades of context: a slow bend, not a turn
Single-year figures can flatten what is really a 20-year story.
Since 2004, the age-adjusted death rate for heart disease has fallen 27%, and the rate for stroke has fallen 24%, according to the AHA's 2026 Statistics Overview.
Over that same span, the age-adjusted mortality rate for dementia rose 47%, a trajectory that now intersects with cardiology through the shared vascular risk factors driving both atherosclerotic disease and cognitive decline.
In raw numbers, heart disease deaths actually rose from 652,486 in 2004 to 680,981 in 2023, a reminder that an aging population can push absolute counts upward even as standardized rates fall.

A narrower label hides a larger burden
The NCHS "heart disease" category captures deaths coded as the underlying cause under ICD-10 codes I00 through I51, a relatively narrow definition centered on ischemic and other primary cardiac disease.
The American Heart Association's 2026 Statistics Update uses a broader, any-mention definition of total cardiovascular disease that includes heart failure, hypertension, arrhythmia, and vascular disease appearing anywhere on the death certificate.
By that broader measure, cardiovascular disease was linked to 915,973 US deaths, or roughly one death every 34 seconds, which is more than cancer and chronic respiratory disease combined.
This distinction matters clinically, because patients who die "with" heart failure or atrial fibrillation as a contributing diagnosis may never appear in the narrower heart disease tally, even though cardiovascular pathology shaped their final illness.
| Metric | Deaths / value | Source and definition |
|---|---|---|
| Heart disease (underlying cause, ICD-10 I00–I51) | 683,491 | NCHS, 2024 final mortality data |
| Stroke (underlying cause, ICD-10 I60–I69) | 166,852 | NCHS, 2024 final mortality data |
| Total cardiovascular disease (any mention on certificate) | 915,973 | AHA, 2026 Statistics Update |
| Annual direct and indirect economic cost of CVD | $414.7B | AHA, 2021–2022 estimate |
| Out-of-hospital cardiac arrest survival to discharge | 10.5% | AHA, 2024 US data |
Sudden cardiac arrest: the survival gap remains wide
The AHA update highlights an area where the gap between knowledge and practice is starkest.
Sudden cardiac arrest, mentioned anywhere on the death certificate, contributed to 380,349 US deaths in 2023, down from 417,957 in 2022.
Among out-of-hospital cardiac arrests in 2024, only 10.5% of patients survived to hospital discharge.
Only 42% of those arrests received bystander CPR, and just 12.6% had a public automated external defibrillator applied before EMS arrival.
This chain of survival, weak at almost every link, represents one of the clearest population-level opportunities for cardiologists to advocate beyond the clinic.

Where the gains came from, and where they did not
Age-adjusted death rates fell for all ten leading causes between 2023 and 2024, with heart disease mortality declining 2.8% and stroke mortality declining a more modest 1.0%.
The largest single driver of the life expectancy gain was the continued fall in unintentional injury deaths, alongside declining COVID-19, heart disease, and cancer mortality.
Yet the AHA notes that optimal cardiovascular health, measured on its eight-component score, remains low across the population, averaging 70 out of 100 in adults and 73 in adolescents.
Modeling cited in the update suggests that roughly 2 million major cardiovascular events could be prevented annually if optimal cardiovascular health were achieved across the adult population.
The report also flags persistent under-utilization of guideline-directed medical therapy as an ongoing quality gap, even as the therapeutic toolkit for atherosclerotic disease and heart failure continues to expand.
Get With The Guidelines registry data cited in the overview show that only 67% of patients with heart failure with reduced ejection fraction receive full quadruple therapy, leaving roughly a third of eligible patients short of guideline-concordant care.
The procedural side of the specialty tells a more optimistic story, with structural heart disease interventions in particular having scaled rapidly over the past decade.
TAVR volume rose from 13,723 procedures in 2011–2013 to 72,991 in 2019, a trajectory that has pushed transcatheter approaches past traditional surgical aortic valve replacement for many patients.
PCI remained the most common cardiovascular procedure nationally with 435,895 cases in 2022, while an estimated 59,087 left atrial appendage occlusion procedures and 4,572 heart transplants, including 64 combined heart-lung transplants, were performed in the most recent reporting years.
A 58-year-old man presents for an annual physical with an LDL cholesterol of 162 mg/dL, a blood pressure of 144/88 mmHg, and a family history of premature coronary disease in his father.
He feels well, exercises occasionally, and has previously declined statin therapy because he "doesn't have any symptoms."
Sharing the population context, that heart disease remains the leading cause of death nationally and that roughly 90% of major cardiovascular events occur in people who never previously carried a cardiovascular diagnosis, can reframe asymptomatic risk as something worth treating now rather than later.
A coronary calcium score, a frank discussion of the 2026 AHA data on cardiovascular health scores, and a structured plan for blood pressure and lipid management give this visit measurable, guideline-anchored next steps rather than a vague exhortation to "live healthier."
Disparities have not closed
Age-adjusted death rates fell across every racial and ethnic group from 2023 to 2024, yet the absolute gaps between groups persisted.
Non-Hispanic Black adults continued to show the highest overall age-adjusted death rate in the country, a pattern that mirrors long-documented disparities in cardiovascular risk factor control and access to preventive cardiology care.
The AHA update separately notes that awareness and control of hypertension and diabetes remain inadequate nationally, particularly among younger adults who may not yet be engaged in regular primary care.
Geography compounds the picture: in 2023, the highest age-adjusted CVD death rate of any state was in Mississippi, nearly double the rate in Massachusetts, the lowest-ranked state.
By race and sex, the highest age-adjusted CVD death rate in 2023 was 360.1 per 100,000 among non-Hispanic Black men and 236.5 per 100,000 among non-Hispanic Black women, each the highest of any racial or ethnic group reported.
| State | Rank | Age-adjusted CVD death rate* |
|---|---|---|
| Mississippi | Highest in US | 312.8 |
| Massachusetts | Lowest in US | 168.5 |

The risk-factor reservoir behind the numbers
Most of the mortality picture above is downstream of risk factors that are common, measurable, and only partially controlled.
An estimated 125.9 million US adults live with hypertension, yet only 60% are aware of the diagnosis and just 22% have it controlled.
Diabetes follows a similar pattern: 29.5 million US adults have diagnosed diabetes, and an additional 9.6 million are estimated to have undiagnosed disease.
Obesity prevalence in adults rose from 37.7% in 2013–2014 to 40.3% in 2021–2023, with a parallel rise in children from 17.2% to 21.1% over the same period.
Using the AHA's cardiovascular-kidney-metabolic staging framework, 90% of US adults already fall into CKM stages 1 through 4, with the largest single group, 49%, sitting in stage 2.
Adverse pregnancy outcomes add an earlier entry point to this risk profile, with a 2022 pregnancy-related mortality rate of 22.3 per 100,000 live births and cardiovascular disease cited as a leading preventable contributor.
Left on its current trajectory, the AHA projects that by 2050, 61% of US adults will be living with hypertension, 61% with obesity, and 27% with diabetes.
| Risk factor | Current prevalence | Projected 2050 |
|---|---|---|
| Hypertension (adults) | 125.9 million (60% aware, 22% controlled) | 61% |
| Obesity (adults) | 40.3% | 61% |
| Diabetes (adults, diagnosed + undiagnosed) | 29.5M dx + 9.6M undx | 27% |
| CKM Stages 1–4 (adults) | 90% | — |
The global picture underscores the same urgency: cardiovascular disease accounted for 19.4 million deaths worldwide in 2021, with an estimated 612 million people currently living with the disease, and high systolic blood pressure remains the single leading CVH-related risk factor worldwide.
Cardiovascular disease, whether counted narrowly as heart disease or broadly as the AHA's any-mention total, remains the leading cause of death in the United States despite a genuinely encouraging overall decline in mortality and a rising life expectancy.
The clinical opportunity sits less in novel therapeutics and more in closing well-known gaps: earlier and more consistent treatment of hypertension and dyslipidemia, broader guideline-directed therapy use in established disease, and community-level investment in bystander CPR and AED access given the persistently low 10.5% survival rate after out-of-hospital cardiac arrest.
With only 22% of hypertensive adults at goal today and projections of 61% adult hypertension and obesity prevalence by 2050, the next two decades of cardiovascular mortality trends will likely be decided by how aggressively these ordinary risk factors are addressed now, not by what new procedure or drug class arrives next.
