A new study from Stanford University School of Medicine and published in the Journal of the American Heart Association reveals a dramatic 89% drop in U.S. heart attack deaths over the past 50 years. Researchers analysed heart disease mortality data from 1970 to 2022 and found that overall heart disease deaths have declined by 66%, largely driven by improved treatment and prevention of heart attacks, which once accounted for over half of all heart disease deaths but now cause less than a third.
This remarkable progress is credited to public health interventions like no-smoking laws, better recognition of early symptoms, advances in emergency care such as bystander CPR, and effective medical treatments. According to Dr. King, these changes have transformed heart attacks from near-certain killers into manageable medical events.
However, the study also raises a red flag: as people survive heart attacks, other heart conditions are rising sharply. Deaths from arrhythmia have increased by 450%, heart failure deaths are up 146%, and hypertensive heart disease deaths have more than doubled. These increases are linked to lifestyle-related risk factors such as obesity, diabetes, and long-term high blood pressure, all of which have risen significantly in the U.S. population since the 1970s.
Senior author Dr. Latha Palaniappan emphasized the importance of long-term prevention, urging people to adopt heart-healthy habits early in life. The American Heart Association’s "Life’s Essential 8" offers a roadmap to reduce risk: eat well, exercise, maintain a healthy weight, quit smoking, sleep better, and control cholesterol, blood pressure, and blood sugar. The message is clear—while the fight against heart attacks has seen great success, the next challenge is preventing chronic heart conditions across the lifespan.
