Prognosis Impact of Frailty Assessed by the Edmonton Frail Scale in the Setting of Acute Coronary Syndrome in the Elderly.

Background: Elderly patients represent a large proportion of patients admitted for acute coronary syndrome (ACS). Whether frailty-defined as a biological syndrome that reflects a state of decreased physiological reserve and vulnerability to stressors-may impact the clinical outcomes in this population remains unclear. We aimed to determine the prevalence of frailty and its impact on mortality in patients aged ≥ 80 years admitted for ACS.
