Global Geriatric Assessment and In-Hospital Bleeding Risk in Elderly Patients with Acute Coronary Syndromes: Insights from the LONGEVO-SCA Registry

Background Bleeding risk scores have shown a limited predictive ability in elderly patients with acute coronary syndromes (ACS). No study explored the role of a comprehensive geriatric assessment to predict in-hospital bleeding in this clinical setting. Methods The prospective multicentre LONGEVO-SCA registry included 532 unselected patients with non-ST segment elevation ACS (NSTEACS) aged 80 years or older. Comorbidity (Charlson index), frailty (FRAIL scale), disability (Barthel index and Lawton-Brody index), cognitive status (Pfeiffer test) and nutritional risk (mini nutritional assessment-short form test) were assessed during hospitalization. CRUSADE score was prospectively calculated for each patient. In-hospital major bleeding was defined by the CRUSADE classification. The association between geriatric syndromes and in-hospitalmajor bleeding was assessed by logistic regressionmethod and the area under the receiver operating characteristic curves (AUC). Results Mean age was 84.3 years (SD 4.1), 61.7% male. Most patients had increased troponin levels (84%). Mean CRUSADE bleeding score was 41 (SD 13). A total of 416 patients (78%) underwent an invasive strategy, and major bleeding was observed in 37 cases (7%). The ability of the CRUSADE score for predicting major bleeding was modest (AUC 0.64). From all aging-related variables, only comorbidity (Charlson index) was independently associated with major bleeding (per point, odds ratio: 1.23, p = 0.021). The addition of comorbidity to CRUSADE score slightly improved the ability for predicting major bleeding (AUC: 0.68). Conclusion Comorbidity was associated with major bleeding in very elderly patients with NSTEACS. The contribution of frailty, disability or nutritional risk for predicting inhospital major bleeding was marginal.
