Patients were re-assessed at 4 months to determine any change in frailty and QoL status as well as the clinical outcome.Results One hundred fifty consecutive patients with symptomatic CAD were recruited in the study. The mean age was 83.7±3.2 years, 99 (66.0%) were men. The clinical presentation was stable angina in 68 (45.3%), the remainder admitted with an acute coronary syndrome including 21 (14.0%) with ST-elevation myocardial infarction. Frailty was present in 28% and 26% by FFP and EFS, respectively, and was associated with a significantly higher CCI (7.5±2.4 in frail, 6.2±2.2 in prefrail, 5.9±1.6 in those without frailty, p=0.005). FFP was significantly related to the physical composite score for QoL, while EFS was significantly related to the mental composite score for QoL (p=0.003). Treatment was determined by the cardiologist: percutaneous coronary intervention in 51 (34%), coronary artery bypass graft surgery in 15 (10%) and medical therapy in 84 (56%). At 4 months, 14 (9.3%) had died. Frail participants had the lowest survival. Cardiovascular symptom status and the mental composite score of QoL significantly improved (52.7±11.5 at baseline vs 55.1±10.6 at follow-up, p=0.04). However, overall frailty status did not significantly change, nor the physical health composite score of QoL (37.2±11.0 at baseline vs 38.5±11.3 at follow-up, p=0.27).Conclusions In patients referred to hospital with CAD, frailty is associated with impaired QoL and a high coexistence of comorbidities. Following cardiac treatment, patients had improvement in cardiovascular symptoms and mental component of QoL.
