STANFORD, CA – In a landmark shift, heart attack deaths have significantly decreased, but new cardiovascular threats loom large.

Immediate Impact

Heart disease remains the leading cause of death globally. However, a recent study reveals a dramatic 66% decline in heart disease death rates among American adults aged 25 and older over the past five decades. Notably, deaths from heart attacks have plummeted by nearly 90%.

Dr. Sara King, the study’s lead author and a second-year internal medicine resident at Stanford University School of Medicine, emphasized the evolution in understanding, causes, and treatment of heart disease. “There have been great strides made in helping people survive initial acute cardiac events that were once considered a death sentence,” King stated.

Key Details Emerge

Despite the positive trend in heart attack survival, the study, published in the Journal of the American Heart Association, highlights a concerning rise in deaths from other types of heart disease, including arrhythmia, heart failure, and hypertensive heart disease, which have increased by 81% in the United States.

Deaths from heart attacks have dropped by nearly 90% over the past 50 years.

By the Numbers

The study analyzed government data on heart disease deaths from 1970 to 2022. In 1970, heart attacks accounted for 54% of all heart-related deaths. By 2022, that figure had fallen to 29%.

The prevalence of obesity rose from 15% in 1970 to 40% in 2022.

Type 2 diabetes and prediabetes now affect nearly half of all U.S. adults.

Expert Analysis

Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health in Denver, cautions that while heart attack fatalities have decreased, the risk of significant disability remains high. “These days, the likelihood of dying from a heart attack is relatively low compared to where it’s been, but the likelihood of significant disability from the heart attack is still high,” Freeman noted.

Freeman, who was not involved in the study, added, “You might develop heart failure — where the heart is unable to pump enough blood to meet the body’s needs and you’re always short of breath. Or maybe you’re on a number of medications for blood pressure, fluid retention, and cholesterol, or you never feel your best.”

Background Context

The rise in cardiovascular risks is attributed to changes in lifestyle and health factors. Obesity, type 2 diabetes, high blood pressure, poor dietary choices, and physical inactivity have surged over the past 50 years. Additionally, the aging Baby Boomer population is reaching an age where heart disease is more likely to develop.

Dr. Latha Palaniappan, senior study author and professor of cardiovascular medicine at Stanford University, stated, “Heart disease hasn’t gone away. The focus now must be on helping people age with strong, healthy hearts by preventing events, and prevention can start as early as childhood.”

What Comes Next

As the landscape of heart disease evolves, emphasis on prevention becomes paramount. The study underscores the need for public health initiatives targeting lifestyle changes and early intervention to mitigate the growing burden of heart disease.
