However, late stent thrombosis remains higher and uniquely associated with drug eluting stents, necessitating improved patient selection and treatment strategies.
Women are slightly more likely to die from heart attacks due to a higher risk after severe presentations, while less severe cases show lower mortality rates. The study highlights the importance of considering sex in ACS research and delivery of care.
Women may have a slightly higher risk of death than men in the 30 days following an acute coronary syndrome, but this difference appears to be due to factors such as severity and type of ACS. After adjusting for clinical characteristics and angiographic data, no significant difference in 30-day mortality was found.
