Heart Attacks Deadlier for Young Americans
A new study finds that severe heart attacks are becoming deadlier for younger Americans under age 55, with death rates rising over the past decade. Younger men saw the largest increases, though younger women remain more likely to die from these events overall, with researchers citing rising obesity and hypertension rates as contributing factors.
The recent study was published in the *Journal of the American Heart Association* and analyzed nearly one million hospitalizations of U.S. adults under the age of 55 between 2011 and 2022. Researchers focused on a severe type of heart attack known as ST-segment elevation myocardial infarction (STEMI), which involves a complete blockage of a coronary artery. While overall deaths from heart attacks have decreased over the last few decades, this study reveals a troubling reversal of that trend for younger adults. The in-hospital death rate for young patients with a first STEMI saw an absolute increase of 1.2% during the study period. For a less severe type of heart attack, NSTEMI, the death rate remained stable. Throughout the study period, 3% of women hospitalized for a severe heart attack died, compared to 2.6% of men. This disparity exists even though 77.2% of these severe heart attacks occurred in young men. One reason for the higher female mortality rate may be that women's heart attack symptoms can be more subtle than the classic chest pain often experienced by men. Women are more likely to experience symptoms like nausea, unexplained fatigue, and pain in the back, jaw, or neck, which can lead to delays in seeking critical treatment. Beyond traditional risk factors like high cholesterol, researchers noted that kidney disease, lower income, and a history of non-tobacco drug use were also strongly associated with heart attack deaths in this younger population. The findings coincide with other alarming health trends. Between 2009 and 2020, obesity rates in adults aged 20-44 rose from about 33% to 41%, and diabetes prevalence also increased. These conditions are major contributors to cardiovascular disease at an earlier age.
