What This Means
This study looked at deaths from pulmonary embolism (a blood clot that blocks arteries in the lungs) among people in the United States who also had atherosclerotic cardiovascular disease, such as heart disease caused by clogged arteries. Using national death records from 2010 to 2023, researchers counted over 152,000 such deaths. After adjusting for age, the death rate rose from about 3.6 to about 5.0 per 100,000 people. The increase was slow from 2010 to 2018 and then much faster from 2018 to 2023.
The increases were not the same everywhere. Black Americans had the highest death rates, while American Indian/Alaska Native and Hispanic/Latinx populations saw the steepest rises. Adults under 65, people in rural areas, and residents of the Western US showed disproportionate increases, and the South had the largest total number of deaths. During the same period, the share of people with atherosclerotic cardiovascular disease rose, alongside high blood pressure, obesity, diabetes, and chronic kidney disease.
This research suggests that pulmonary embolism is an increasingly important cause of death in people with cardiovascular disease, and that some groups are affected more than others. Because the study uses population-level records and shows parallel trends rather than proving cause, it cannot say why the rise occurred. It may help guide attention toward younger adults and underserved communities.
