Here’s the good news: Deaths due to ischemic heart disease — when coronary arteries are blocked — fell by more than half from 1990 to 2023 in the United States, thanks to better control of up to a dozen risk factors. What’s still on the table: Almost 9 out of 10 of the most recent deaths could have been prevented by better managing those risk factors.
Much of the progress recorded since the start of the Global Burden of Disease study, published Wednesday in JAMA Cardiology, stemmed from drops in deaths from smoking (down 33.3%) and particulate air pollution (down 74.9%). But in the last year of the study, 419,000 of the estimated 473,000 coronary artery disease deaths — or 88.8% — were still linked to modifiable risk factors.
