Abstract 12602: Poor Quality of Life in Patients With and Without Frailty: Co-prevalence and Prognostic Implications in Patients Undergoing Percutaneous Coronary Interventions and Cardiac Catheterization

Introduction: Relationship of QOL and frailty are poorly defined. Hypothesis: To study the prevalence and prognosis of poor QOL in frail patients. Methods: Predismissal standardized tests for frailty and QOL in 2 cohorts were administered. In cohort 1, 629 patients ≥ 65 years underwent percutaneous coronary intervention (PCI) from 2005-2008, frailty (Fried) and QOL [SF-36 and SAQ] were ascertained. Cohort 2 [921 patients, 535 PCI, ≥55 years] underwent cardiac catheterization from 2014-18, frailty (Rockwood) and QOL (Likert) were determined. Results: In cohort 1, 19%; and 20% in cohort 2 were frail. Lower median SAQ (58.9 vs. 82.2); physical (29.5 vs. 43.9) and mental (49.2 vs. 57.4) scores of SF-36 in cohort 1 higher rates of fair/poor health (56% vs 18%) in cohort 2 (all comparisons, p<0.001) was seen in frail patients. As compared to without, frail patients were 5 times more likely (59% vs. 11%, p<0.001) in cohort 1 and 7 times more likely (56% vs. 8%) in cohort 2 to have poor QOL. Adjusted three year all-cause death and death/myocardial infarction (MI) was significantly higher for patients undergoing PCI with frailty; [HR (95% CI) death, 4.20 (2.63, 6.68) and death or MI HR 2.72 (1.91, 3.87), p<0.001) and with poor QOL [HR death 2.47 (1.59, 3.84) and death or MI 1.61 (1.16, 2.24) p<0.001). There was no significant interaction between frailty and QOL (p=0.64) indicating their independent prognostic influence. Conclusions: Poor QOL is commonly seen with frailty. Both frailty and poor QOL had significant and independent association with long-term survival.
