How a National Partnership Is Preventing a Million Heart Attacks and Strokes

The Public-Private Initiative Changing America's Cardiovascular Health

Public Health Cardiology Policy

In 2012, faced with this staggering burden, the U.S. Department of Health and Human Services launched an audacious initiative called Million Hearts® with a single, clear goal: prevent 1 million heart attacks and strokes within five years 1 . What made this initiative different was its innovative approach—uniting public and private sectors in a coordinated attack on cardiovascular disease from multiple fronts 2 .

Heart attacks and strokes to prevent

A Nation Aligns Against a Common Enemy

Cardiovascular disease remains the leading cause of death in the United States for men and women across all races and ethnicities 7 . Despite having effective tools for prevention and treatment, these interventions remained significantly underutilized .

"The Million Hearts network described in this article is unique in its membership at the national level, agreement on outcomes, its powerful information-sharing abilities that require few resources, and its decentralized structure," noted one research study 2 .

Million Hearts® emerged as a coordinated response, co-led by the Centers for Disease Control and Prevention (CDC) and the Centers for Medicare & Medicaid Services (CMS) 3 . The initiative's strength comes from its ability to align diverse partners—including federal agencies, state and local health departments, health care systems, clinicians, pharmacists, insurers, community organizations, and consumer groups—around a shared aim and evidence-based strategies 2 7 .

This network approach creates opportunities to leverage more resources, reduce costs, and create solutions that would be impossible for any single organization to tackle alone 2 .

The Million Hearts® Game Plan: ABCS and Beyond

The initiative's strategy focuses on implementing a small set of priorities known to have outsized impact on cardiovascular health 1 . These are organized into two complementary approaches:

Building Healthy Communities

Million Hearts® supports strategies that help communities become healthier, including decreasing tobacco use, increasing physical activity, and reducing exposure to particle pollution 1 . Early initiatives included efforts to eliminate artificial trans fat from the food supply and reduce sodium consumption 7 .

Progress in community health initiatives
Optimizing Clinical Care

In clinical settings, the initiative promotes what's known as the ABCS of heart attack and stroke prevention . This clinical focus has expanded over time to include increasing participation in cardiac rehabilitation programs and promoting team-based care models 1 .

Aspirin Therapy

B
Blood Pressure Control

C
Cholesterol Management

Controlling lipid levels with statins when indicated

S
Smoking Cessation

Supporting tobacco use prevention and quitting

Focusing on Health Equity

Million Hearts® maintains a committed focus on specific populations experiencing inequities, including pregnant and postpartum women with hypertension, people from racial/ethnic minority groups, people with behavioral health issues who use tobacco, those with lower incomes, and people living in rural areas or other 'access deserts' 1 3 .

This health equity focus recognizes that cardiovascular disease is a primary contributor to racial disparities in life expectancy 7 . Recent campaigns like "Live to the Beat" specifically empower Black adults to pursue heart-healthy lifestyles on their own terms 6 .

Inside a Landmark Experiment: The Million Hearts® Risk Reduction Model

One of the most innovative components of the Million Hearts® initiative is the Cardiovascular Disease Risk Reduction Model, a pragmatic, cluster-randomized trial that represented a paradigm shift in how cardiovascular risk is measured and managed 8 9 .

The Experiment

From 2017 to 2021, the Centers for Medicare & Medicaid Services conducted this large-scale experiment involving 516 U.S.-based primary care and specialty practices, health centers, and hospital-based outpatient clinics 9 . These organizations were randomly assigned to either an intervention group or a standard care control group.

The intervention had two key components:
  1. Health care organizations agreed to perform guideline-concordant care, including routine CVD risk assessment using the pooled cohort equations to calculate patients' 10-year risk of heart attack or stroke 9
  2. CMS provided payments to organizations for assessing risk and for successfully reducing risk among high-risk Medicare beneficiaries 9

A New Approach to Incentives

Traditional quality measures typically reward clinical practices for the proportion of patients who reach specific clinical targets like blood pressure or cholesterol goals. The Million Hearts Model instead shifted the incentive focus to mean risk reduction, concentrating on treating medium- to high-risk patients who may need care the most 8 .

Organizations received performance-based payments tied to reducing the calculated cardiovascular risk scores of their high-risk patients, not just managing individual risk factors 9 .

Groundbreaking Results

The model demonstrated significant success over a five-year period:

The Scientist's Toolkit: Key Resources Powering the Prevention Effort

The Million Hearts® initiative relies on a sophisticated array of data and implementation tools to track progress, identify disparities, and support evidence-based interventions:

Interactive Atlas of Heart Disease and Stroke

Provides county-level maps of heart disease and stroke. Displays social determinants of health and health services data; supports geographic analysis of disparities 5 .

CDC
CDC WONDER Database

Promotes data-driven decision making. Provides access to detailed mortality data; includes timeliness and public accessibility 5 .

CDC
Chronic Disease Indicators

Enables tracking of state-level chronic disease data. Includes 124 indicators covering social determinants, behavioral risk factors, and health outcomes 5 .

CDC
AHRQ Cardiovascular Dashboard

Helps practices calculate performance measures. Allows tracking of blood pressure control, smoking cessation, and aspirin use over time 5 .

Tangible Impact and the Path Forward

The results of the Million Hearts® initiative speak for themselves. In its first five-year cycle (2012-2016), Million Hearts® prevented an estimated 135,000 heart attacks, strokes, and related acute cardiovascular events and saved $5.6 billion in direct medical costs 4 .

The Path Forward

As Million Hearts® continues into its next phase (Million Hearts® 2027), the initiative remains dedicated to its founding vision while adapting to new challenges and opportunities 3 . The COVID-19 pandemic highlighted significant gaps and vulnerabilities in the nation's cardiovascular health, creating increased urgency to improve prevention efforts 4 .

The initiative continues to evolve, exploring how emerging fields like genomics and precision medicine might complement current population-based approaches to help identify high-risk individuals earlier and tailor interventions more effectively 7 .

Million Hearts® represents a powerful model of what's possible when diverse stakeholders align around common goals, evidence-based strategies, and a shared commitment to health equity. As the initiative demonstrates, preventing a million heart attacks and strokes isn't just a bold aspiration—it's an achievable goal when a nation commits to working together, one heart at a time.
