Top Cause of Death in the U.S. Takes a Life Every 34 Seconds

Heart disease claims a life every 34 seconds in the U.S., making it the nation’s leading cause of death, according to a new report.

“These statistics should alarm all of us—they represent our friends and loved ones,” says Dr. Keith Churchwell, president of the American Heart Association.

The 2025 Heart Disease and Stroke Statistics Update found cardiovascular disease caused 941,652 deaths in 2022, surpassing cancer, accidents, and COVID-19.

“Too many people are dying from heart disease and stroke, the fifth leading cause of death,” Churchwell adds. “Together, they claim more lives than all cancers and accidental deaths combined.”

Rising Risk Factors: Hypertension and Obesity Could Impact 180 Million U.S. Adults by 2050

Key risk factors—including high blood pressure, diabetes, and obesity—are rising. If trends continue, hypertension and obesity could affect 180 million U.S. adults by 2050.

Dr. Dhruv Kazi, a Harvard cardiologist, notes lifestyle changes, especially in youth, may have been influenced by COVID-19.

A poor diet remains a major contributor. Most Americans don’t eat enough unprocessed foods, and the report highlights the benefits of plant-based diets like Mediterranean and vegetarian plans. Sleep, exercise, and stress management also play key roles.

Environmental factors—including income and neighborhood resources—shape dietary choices. Rising grocery costs make healthy eating harder, and marginalized communities face greater obstacles, worsening health disparities.

“The age-adjusted obesity-related cardiovascular mortality rate was highest among Black individuals, followed by American Indian and Alaska Native individuals,” the report states.

Smoking Rates Plummet: A Drop from 42% in the 1960s to 11.5% Today

On a positive note, smoking rates have dropped from 42% in the 1960s to 11.5% today.

“Excess weight now costs us more lives than smoking,” says Dr. Latha Palaniappan, a Stanford cardiologist.

Cholesterol levels have also improved, showing awareness efforts are working.

“The disparities in risk and outcomes demand targeted interventions,” Kazi emphasizes. “Breakthrough therapies aren’t enough—they must be accessible and affordable.”

The NIH recommends regular heart screenings starting at age 20, especially for those with a family history. These include blood pressure, cholesterol, and glucose tests.

“While we’ve made progress, much work remains,” Kazi concludes.
