Differences in Symptomatology and Clinical Course of Acute Coronary Syndromes in Women ≤45 Years of Age Compared to Older Women

Acute coronary syndromes (ACS) in young people are rare. The data regarding differences in symptoms in relation to age are scarce, which may have an influence on outcomes. The aim of this study was to evaluate the differences in the clinical course of ACS between younger women (≤45 years old) and older women (63-64 years old).
