Frailty is common among elderly patients with coronary artery disease.It prolongs the length of hospitalization and can independently predict poor short-term and long-term prognosis in patients with acute coronary syndrome (ACS). The assessment of frailty can contribute to a more comprehensive risk stratification in ACS patients.For patients with coronary artery disease seeking reperfusion therapy, frailty can be an independent predictor for higher short-term and long-term mortality rates after PCI and can increase the mortality rate after coronary artery bypass grafting (CABG). Previous findings suggest that frailty should be included in the preoperative risk assessment model of reperfusion therapy for patients with coronary artery disease.In addition, frailty assessment is helpful in predicting the mortality after reperfusion therapy.
