U.S. Sees Decline in Cardiovascular Disease Deaths After Five-Year Rise
A recent report from the American Heart Association (AHA) indicates a decline in deaths from cardiovascular diseases, including heart disease and stroke, in the United States in 2023. This reduction follows a five-year upward trend, which some experts suggest may have been influenced by the COVID-19 pandemic. Despite the decrease, heart disease remains the primary cause of death in the U.S., with stroke ranking fourth.
Together, these conditions accounted for over a quarter of all U.S. deaths in 2023, exceeding fatalities from all forms of cancer and accidental deaths combined.
Key Statistical Findings: A Glimpse into 2023
The AHA's 2026 Heart Disease and Stroke Statistics Update, published in Circulation, shows modest improvements in age-adjusted death rates for cardiovascular diseases (CVD) for the year 2023.
- Total CVD Deaths: 915,973 deaths, a decrease from 941,652 in 2022. The age-adjusted rate was 218.3 per 100,000 people.
- Coronary Heart Disease Deaths: 349,470 deaths, down from 371,506 in 2022. This represents approximately two deaths every three minutes.
- Stroke Deaths: 162,639 deaths, a reduction from 165,393 in 2022. On average, a person died of stroke every 3 minutes and 14 seconds.
Approximately 25,000 fewer deaths from cardiovascular disease and stroke occurred in 2023 compared to 2022.
Persistent Risk Factors and the CKM Syndrome
Approximately half of all U.S. adults live with some form of cardiovascular disease. The prevalence of contributing risk factors remains high:
- High Blood Pressure: Affects 125.9 million U.S. adults, or 47.3% of the adult population.
- Diagnosed Diabetes: Nearly 29.5 million U.S. adults have been diagnosed with diabetes.
- Obesity/Severe Obesity: Impacts about 50% of U.S. adults. Childhood obesity in those aged 2-19 increased from 25.4% to 28.1%.
For the first time, the report includes a chapter on Cardiovascular-Kidney-Metabolic (CKM) syndrome, a health disorder that links heart disease, kidney disease, diabetes, and obesity. Data indicates that nearly 90% of U.S. adults have some level of CKM syndrome, and over 80% of young and middle-aged adults show early CKM risk factors.
Stroke Trends: A Closer Look at Age Groups
While overall stroke deaths decreased, increases were observed in crude stroke death rates for specific age groups between 2013 and 2023:
- Ages 25-34: An 8.3% increase.
- Ages 85+: An 18.2% increase.
Prevention at the Forefront: Life's Essential 8
The AHA highlights its "Life's Essential 8™" guidance as a framework for individual habit changes that protect heart health. This guidance includes four health behaviors and four health factors:
- Health Behaviors: Eating better, being more active, quitting tobacco, and getting healthy sleep.
- Health Factors: Managing weight, controlling cholesterol, managing blood sugar, and managing blood pressure.
Studies cited in the update indicate that ideal cardiovascular health, as measured by Life's Essential 8, is associated with a 74% lower risk of cardiovascular events.
Optimal adherence to these measures could prevent up to 40% of annual all-cause and CVD deaths among adults and is correlated with improved brain health, including reduced dementia risk. Experts state that up to 80% of heart disease and stroke is preventable through lifestyle changes and management of chronic health conditions.
Adherence Challenges: A Hurdle to Health
Despite the documented benefits, adherence to these preventative measures remains low:
- Diet scores are the lowest among both adults and youth.
- Only 25.3% of U.S. adults meet national physical activity guidelines.
- E-cigarettes are the most used tobacco product among youth, with 18.1% of high school students reporting use.
- Less than half (43.5%) of U.S. adults with Type 2 diabetes have their condition under control.
Only one in four U.S. adults meets national guidelines for both aerobic and muscle-strengthening exercise.
Cardiologist's Prescription: Actionable Habits
Cardiologists outline several habits to improve heart health:
- Increase Plant Food Consumption: Incorporate more fruits, vegetables, nuts, seeds, beans, and whole grains. Plant-based diets are associated with improved cardiovascular, gut, and brain health, and are typically lower in saturated fat and higher in fiber.
- Reduce Sedentary Behavior: Increase physical activity to strengthen the heart, reduce blood pressure, lower LDL cholesterol, increase HDL cholesterol, and decrease inflammation. Even short periods of movement contribute to cardiovascular health.
- Foster Social Connections: Maintaining social connections can positively affect heart health. Poor social relationships, loneliness, and depression are associated with increased risk of cardiovascular disease.
- Opt for Unsweetened Beverages: Prioritize plain water, flavored sparkling water, fruit-infused water, low-fat milk, unsweetened alternative milks, or unsweetened coffee/tea. Sugar-sweetened and artificially sweetened drinks are linked to an increased risk of heart problems.
- Cease Smoking: Quitting smoking reduces plaque buildup in arteries, improves circulation, and decreases the risk of clot formation. The risk of stroke declines within four years of quitting to a level comparable to non-smokers.
For individuals finding habit changes challenging, starting with small, specific goals is suggested.
Policy, Community, and Economic Impact
Public health experts have proposed community-level policy changes to support healthier choices and reduce heart disease risk. These include:
- Creating green spaces to facilitate safe exercise.
- Reducing sodium in the food supply.
- Expanding healthcare initiatives for diabetes prevention and obesity treatment.
- Implementing financial incentives for cardiovascular risk factor reduction.
Cardiovascular disease represents a significant financial burden on the U.S. economy, with an estimated average of $414.7 billion in direct and indirect costs from 2021 to 2022.
