A bold revelation: women's hearts are at greater risk, even with less plaque buildup. This surprising finding challenges conventional wisdom and sparks a crucial conversation about heart health.
The American Heart Association's recent study, published in Circulation: Cardiovascular Imaging, has unveiled a paradox. While women typically have lower levels of artery-clogging plaque, this doesn't shield them from cardiovascular events. In fact, the risk of heart attacks and chest pain seems to manifest with less plaque in women, especially post-menopause, compared to men.
DALLAS, Feb. 23, 2026 - The study's key takeaway is that women's smaller coronary arteries make them more vulnerable to even small amounts of plaque. This vulnerability is a critical factor that has been overlooked in the past.
Heart disease is the leading cause of illness and death globally, and women, despite having lower plaque prevalence, are not immune. This study evaluated over 4,200 adults, with a focus on plaque quantity and its impact on heart conditions. The findings were eye-opening:
- Women had significantly less plaque in their coronary arteries (55% of women vs. 75% of men) and lower plaque volume (78 mm3 vs. 156 mm3 in men).
- Despite this, women faced the same risks as men for fatal and non-fatal heart attacks and chest pain hospitalizations.
- Women's heart risk increased at lower plaque levels compared to men. Their risk started rising at 20% plaque burden, while men's risk began at 28%.
Dr. Borek Foldyna, the study's senior author, emphasized that women are not protected by lower plaque volumes. "Moderate increases in plaque burden in women can have a disproportionate impact on their heart health," he explained.
Stacey E. Rosen, M.D., FAHA, and volunteer president of the American Heart Association, highlighted the importance of recognizing these gender differences. "We need to address the fundamental biological differences in how health conditions manifest in women and men. This study is a step towards reducing the cardiovascular disease burden for all."
The American Heart Association's 2026 Heart Disease and Stroke Statistics report a stark reality: cardiovascular disease caused 47.3% of deaths from cardiovascular disease in females of all ages, a total of 433,254 deaths.
This study, a subset of the PROMISE trial, followed 4,267 adults (average age 60; 51% women) for about two years. The lead author, Dr. Jan Brendel, emphasized the need for further research to understand these gender-specific risks better.
And this is the part most people miss: the impact of small plaque buildups in women's smaller coronary arteries. It's a critical factor that could change how we approach heart health for women.
So, what do you think? Is this a game-changer for heart health awareness? Let's discuss in the comments and share our thoughts on this crucial topic!
