ABSTRACT
INTRODUCTION:
Elderly patients with acute coronary syndrome (ACS) have a higher risk of adverse cardiovascular events and may be frail but are underrepresented in clinical trials. Previous studies have proposed that frailty assessment is a better tool than chronological age, in assessing older patients' biological age, and may exceed conventional risk scores in predicting the prognosis. Therefore, we wanted to investigate the prevalence and impact on 12-month outcomes of frailty in patients ≥70 years with ACS referred for coronary angiography (CAG).METHODS:
Patients ≥70 years with ACS referred for CAG underwent frailty scoring with the clinical frailty scale (CFS). Patients were divided into three groups depending on their CFS robust (1-3), vulnerable (4), and frail (5-9) and followed for 12 months.RESULTS:
Of 455 patients, 69 (15%) patients were frail, 79 (17%) were vulnerable, and 307 (68%) were robust. Frail patients were older (frail 80.9 ± 5.7 years, vulnerable 78.5 ± 5.5 years, and robust 76.6 ± 4.9 years, p < 0.001) and less often treated with percutaneous coronary intervention (frail 56.5%, vulnerable 53.2%, and robust 68.6%, p = 0.014). 12-month mortality was higher among frail patients (frail 24.6%, vulnerable 21.8%, and robust 6.2%, p < 0.001). Frailty was associated with a higher mortality after adjustment for age, sex, comorbidities, the Global Registry of Acute Coronary Events (GRACE) score, and revascularisation (HR 2.67, 95% CI 1.30-5.50, p = 0.008). There was no difference between GRACE and CFS in predicting 12-month mortality (p = 0.893).CONCLUSIONS:
Fifteen percent of patients ≥70 years old with ACS referred for CAG are frail. Frail patients have significantly higher 12-month mortality. GRACE and CFS are similar in predicting 12-month mortality.Key words
