π©Ί New heart attack definition helps women get better care
Heart disease is the leading cause of death for women globally, resulting in over 300,000 annual deaths in the United States. Cardiovascular disease affects about 44% of US women currently, with projections showing it could hit nearly 60% by 2050. Previously, heart attack diagnosis relied on simple checklists that often missed women's specific symptoms. However, the Fifth Universal Definition of Myocardial Infarction launched in August 2026. This update changes diagnosis methods to better account for what causes heart damage in women. π©Ί
