The role of frailty in acute coronary syndrome patients has not been fully explored. Our study aims to assess the prevalence of frailty and its impact on in-hospital adverse outcomes of patients aged ⩾75 years admitted for acute coronary syndrome. Methods: This prospective, observational study included patients aged ⩾75 years admitted due to type 1 myocardial infarction in four tertiary hospitals. Frailty was assessed by the SHARE-FI index. The primary endpoint was the combination of in-hospital death or non-fatal myocardial (re)infarction. Secondary endpoints included the assessment of individual rates of (re)infarction, mortality, stroke, major bleeding and the combination of in-hospital death, (re)infarction and mortality. Results: A total of 202 patients were analysed. Frail patients (n=71, 35.1%) were older, more often women, had higher rates of comorbidities, and a higher risk profile according to GRACE, TIMI and CRUSADE scores at admission. The primary endpoint was significantly more frequent among frail patients (9.9% vs. 1.5%; P=0.006), as well as the combination of death, myocardial infarction and stroke (11.3% vs. 1.5%; P=0.002), driven mainly by a higher mortality rate (8.5% vs 0.8%; P=0.004). On multivariate analysis, frailty phenotype was an independent predictor of major adverse cardiac events (odds ratio 7.13; 95% confidence interval 1.43-35.42). Conclusions: Over one third of elderly patients with high-risk acute coronary syndrome are frail. Frailty phenotype is an important and independent prognostic marker in these patients.
