OBJECTIVES: The aim of this study was to evaluate the impact of frailty in the elderly on response to cardiac resynchronization therapy (CRT).
BACKGROUND: CRT has been shown to improve symptoms and outcome of patients with congestive heart failure (HF) and impaired left ventricular ejection fraction (LVEF). The impact of frailty on the results of CRT is unknown.
METHODS: Frailty defined as <14 of 17 points using the ONCODAGE (Outil de dépistage gériatrique en oncologie) G8 score was assessed before device implantation in candidates for CRT who were >70 years of age. The primary endpoint was the response to CRT, defined as an improvement of >5% of the LVEF and the absence of hospitalization for HF or cardiovascular death at 9 months.
RESULTS: Ninety-two of 151 included patients (61%) were frail, and 89 (59%) were responders. Frailty was more frequent in nonresponders: 45 of 62 (73%) versus 47 of 89 (53%) (p = 0.014) and was identified as an independent predictor of nonresponse to CRT (R = 0.30; 95% confidence interval: 0.02 to 0.59; p = 0.039). Frailty was associated with a higher cumulative probability of hospitalization for HF (log-rank p = 0.032) and of all-cause death (log-rank p = 0.033). A G8 score <10.25 correlated with hospitalization for HF or death at 9 months (area under the curve: 0.75; 95% confidence interval: 0.63 to 0.87; cutoff <10.25; 77% sensitivity, 63% specificity).
CONCLUSIONS: Frailty is as an independent predictor of nonresponse to CRT. Frail patients implanted with CRT devices have a higher risk of hospitalization for HF and mortality. Routine comprehensive geriatric assessment at the time of screening for device therapy should be recommended to optimize management.
