ABSTRACT
BACKGROUND: Elderly patients with acute coronary syndromes (ACS) are at higher risk for complications and health care resources expenditure. No previous study has assessed the specific contribution of frailty and other geriatric syndromes to the in-hospital economic cost in this setting. METHOD: Unselected patients with ACS aged ≥75 years were prospectively included. A comprehensive geriatric assessment was performed during hospitalisation. Hospitalisation-related cost per patient was calculated with an analytical accountability method, including hospital stay-related expenditures, interventions, and consumption of devices. Expenditure was expressed in Euros (2019). The contribution of geriatric syndromes and clinical factors to the economic cost was assessed with a linear regression method. RESULTS: A total of 194 patients (mean age 82.6 years) were included. Mean length of hospital stay was 11.3 days. The admission-related economic cost was 6,892.15 per patient. Most of this cost was attributable to hospital length of stay (77%). The performance of an invasive strategy during the admission was associated with economic cost (p=0.008). Of all the ageing-related variables, comorbidity showed the most significant association with economic cost (p=0.009). Comorbidity, disability, nutritional risk, and frailty were associated with the hospital length of stay-related component of the economic cost. The final predictive model of economic cost included age, previous heart failure, systolic blood pressure, Killip class at admission, left main disease, and Charlson index. CONCLUSIONS: Management of ACS in elderly patients is associated with a significant economic cost, mostly due to hospital length of stay. Comorbidity mostly contributes to in-hospital resources expenditure, as well as the severity of the coronary event.

BACKGROUND: The magnitude of the association between diabetes (DM) and outcomes in elderly patients with acute coronary syndromes (ACS) is controversial. No study assessed the prognostic impact of DM according to frailty status in these patients. METHODS: The LONGEVO-SCA registry included unselected ACS patients aged ≥ 80 years. Frailty was assessed by the FRAIL scale. We evaluated the impact of previous known DM on the incidence of death or readmission at 6 months according to status frailty by the Cox regression method. RESULTS: A total of 532 patients were included. Mean age was 84.3 years, and 212 patients (39.8%) had previous DM diagnosis. Patients with DM had more comorbidities and higher prevalence of frailty (33% vs 21.9%, p = 0.002). The incidence of death or readmission at 6 months was higher in patients with DM (HR 1.52, 95% CI 1.12-2.05, p 0.007), but after adjusting for potential confounders this association was not significant. The association between DM and outcomes was not significant in robust patients, but it was especially significant in patients with frailty [HR 1.72 (1.05-2.81), p = 0.030, p value for interaction = 0.049]. CONCLUSIONS: About 40% of elderly patients with ACS had previous known DM diagnosis. The association between DM and outcomes was different according to frailty status.

BACKGROUND: Prognostic impact of anaemia in the elderly with acute coronary syndromes has not been specifically analysed, and little information exists about causes of mortality in this setting. METHODS: We prospectively included consecutive patients with acute coronary syndromes. Anaemia was defined as haemoglobin < 130 g/L in men, and < 120 g/L in women. Primary outcome was mid-term mortality and its causes. Analyses were performed by Cox regression method. RESULTS: We included 2128 patients, of whom 394 (18.6%) were aged 75 years or older. Anaemia was more common in the elderly (40.4% vs 19.5%, p <0.001). Mean follow-up was 386 days. Anaemia independently predicted overall mortality (HR 1.47, 95% CI 1.05-2.06), cardiac mortality (HR 1.76, 95% CI 1.06-2.94) and non-cardiac mortality (HR 1.59, 95% CI 1.03-2.45) in the overall cohort. In young patients the association between anaemia and mortality was significant only for non-cardiac causes. The association between anaemia and mortality was not significant in the elderly (HR 1.08, 95% CI 0.71-1.63, p 0.736). CONCLUSIONS: The impact of anaemia on cause specific of mortality seem to be different according to age subgroup. The association between anaemia and mortality was not observed in elderly patients from our series.

INTRODUCTION AND OBJECTIVES: The aim of this study was to analyze the clinical profile, management, and prognosis of ST segment elevation myocardial infarction-related cardiogenic shock (STEMI-CS) requiring interhospital transfer, as well as the prognostic impact of structural variables of the treating centers in this setting. METHODS: This study included patients with STEMI-CS treated at revascularization-capable centers from 2016 to 2020. The patients were divided into the following groups: group A: patients attended throughout their admission at hospitals with interventional cardiology without cardiac surgery; group B: patients treated at hospitals with interventional cardiology and cardiac surgery; and group C: patients transferred to centers with interventional cardiology and cardiac surgery. We analyzed the association between the volume of STEMI-CS cases treated, the availability of cardiac intensive care units (CICU), and heart transplant with hospital mortality. RESULTS: A total of 4189 episodes were included: 1389 (33.2%) from group A, 2627 from group B (62.7%), and 173 from group C (4.1%). Transferred patients were younger, had a higher cardiovascular risk, and more commonly underwent revascularization, mechanical circulatory support, and heart transplant during hospitalization (P<.001). The crude mortality rate was lower in transferred patients (46.2% vs 60.3% in group A and 54.4% in group B, (P<.001)). Lower mortality was associated with a higher volume of care and CICU availability (OR, 0.75, P=.009; and 0.80, P=.047). CONCLUSIONS: The proportion of transfers in patients with STEMI-CS in our setting is low. Transferred patients were younger and underwent more invasive procedures. Mortality was lower among patients transferred to centers with a higher volume of STEMI-CS cases and CICU.

AIMS: This study aimed to assess, in patients with cardiogenic shock secondary to unprotected left main coronary artery-related myocardial infarction (ULMCA-related AMICS), the incidence and predictors of no recovery of left ventricular function during the admission. METHODS AND RESULTS: This was an observational study conducted at two tertiary care centres (2012-20). The main outcome measured was death or requirement for heart transplantation (HT) or left ventricular assist devices (LVAD) during the admission. A total of 70 patients were included. Percutaneous coronary intervention (PCI) was successful in 53/70 patients (75.7%). The combined endpoint of death or requirement of HT or LVAD during the admission occurred in 41/70 patients (58.6%). The highest incidence of the primary endpoint was observed among patients with profound shock and occluded left main coronary artery (LMCA) (20/23, 87%, P < 0.001). Although a successful PCI reduced the incidence of the event in the whole cohort (51.9% vs. 82.4% in failed PCI, P = 0.026), this association was not observed among this last group of complex patients (86.7% vs. 87.5% in failed PCI, P = 0.731). The predictive model included left ventricular ejection fraction, baseline ULMCA Thrombolysis In Myocardial Infarction flow, and severity of shock and showed an optimal ability for predicting death or requirements for HT or LVAD during the admission (area under the curve 0.865, P < 0.001). CONCLUSIONS: ULMCA-related AMICS was associated with a high in-hospital mortality or need for HT or LVAD. Prognosis was especially poor among patients with profound shock and baseline occluded LMCA, with a low probability of recovery regardless of successful PCI.

BACKGROUND: A significant proportion of cases of cardiogenic shock (CS) are due aetiologies other than acute coronary syndromes (non ACS-CS). We assessed differences regarding clinical profile, management, and prognosis according to the cause of CS among nonselected patients with CS from a large nationwide database. METHODS: We performed an observational study including patients admitted from the hospitals of the Spanish National Health System (SNHS) with a principal or secondary diagnosis code of CS (2016-2019). Data were obtained from the Minimum Basic Data Set (MBDS). Hospitals were classified according to the availability of cardiology related resources, as well as the availability of Intensive Cardiac Care Unit (ICCU). RESULTS: A total of 10,826 episodes of CS were included, of whom 5,495 (50.8%) were non-ACS related. Non ACS-CS patients were younger (71.5 vs. 72.4 years) and had a lower burden of arteriosclerosis-related comorbidities. Non ACS-CS cases underwent less often invasive procedures and presented lower in-hospital mortality (57.1% vs. 61%,p < 0.001). The most common main diagnosis among non ACS-CS was acute decompensation of chronic heart failure (ADCHF) (35.4%). A lower risk-adjusted in-hospital mortality rate was observed in high volume hospitals (52.6% vs. 56.7%; p < 0.001), as well as in centers with ICCU (OR: 0.71; CI 95%: 0.58-0.87; p < 0.001). CONCLUSIONS: More than a half of cases of CS were due to non-ACS causes. Non ACS-CS cases are a very heterogeneous group, with different clinical profile and management. Management at high-volume hospitals and availability of ICCU were associated with lower risk adjusted mortality among non ACS-CS patients.

AIMS: Cardiogenic shock (CS) is associated with high mortality. The purpose of this study was to assess the impact of hospital structure-related variables on mortality in patients with CS treated at percutaneous and surgical revascularization capable centres (psRCC) from a large nationwide registry. METHODS AND RESULTS: Retrospective observational study including consecutive patients with main or secondary diagnosis of CS and ST elevation myocardial infarction (STEMI). Patients discharged from Spanish National Healthcare System psRCC were included (2016-20). The association between the volume of CS cases attended by each centre, availability of intensive cardiac care unit (ICCU) and heart transplantation (HT) programmes, and in-hospital mortality was assessed by multilevel logistic regression models. The study population consisted of 3074 CS-STEMI episodes, of whom 1759 (57.2%) occurred in 26 centres with ICCU. A total of 17/44 hospitals (38.6%) were high-volume centres, and 19/44 (43%) centres had HT programmes availability. Treatment at HT centres was not associated with a lower mortality (P = 0.121). Both high volume of cases and ICCU showed a trend to an association with lower mortality in the adjusted model [odds ratio (OR): 0.87 and 0.88, respectively]. The interaction between both variables was significantly protective (OR 0.72; P = 0.024). After propensity score matching, mortality was lower in high-volume hospitals with ICCU (OR 0.79; P = 0.007). CONCLUSION: Most CS-STEMI patients were attended at psRCC with high volume of cases and ICCU available. The combination of high volume and ICCU availability showed the lowest mortality. These data should be taken into account when designing regional networks for CS management.

BACKGROUND: The Impella pump has emerged as a promising tool in patients with cardiogenic shock (CS). Despite its attractive properties, there are scarce data on the specific clinical setting and the potential role of Impella devices in CS patients from routine clinical practice. METHODS: This is an observational, retrospective, single center, cohort study. All consecutive patients with diagnosis of CS and undergoing support with Impella 2.5®, Impella CP® or Impella 5.0® from April 2015 to December 2020 were included. Baseline characteristics, management and outcomes were assessed according to CS severity, age and cause of CS. Main outcome measured was in-hospital mortality. RESULTS: A total of 50 patients were included (median age: 59.3 ± 10 years). The most common cause of CS was acute coronary syndrome (ACS) (68%), followed by decompensation of previous cardiomyopathy (22%). A total of 13 patients (26%) had profound CS. Most patients (54%) improved pulmonary congestion at 48 h after Impella support. A total of 19 patients (38%) presented significant bleeding. In-hospital mortality was 42%. Among patients with profound CS (n = 13), five patients were previously supported with venoarterial extracorporeal membrane oxygenation. A total of eight patients (61.5%) died during the admission, and no patient achieved ventricular recovery. Older patients (≥ 67 years, n = 10) had more comorbidities and the highest mortality (70%). Among patients with ACS (n = 34), 35.3% of patients had profound CS; and in most cases (52.9%), Impella support was performed as a bridge to recovery. In contrast, only one patient from the decompensated cardiomyopathy group (n = 11) presented with profound CS. In 90.9% of these cases, Impella support was used as a bridge to cardiac transplantation. There were no cases of death. CONCLUSIONS: In this cohort of real-life CS patients, Impella devices were used in different settings, with different clinical profiles and management. Despite a significant rate of complications, mortality was acceptable and lower than those observed in other series.
ABSTRACT
AIMS: Cardiogenic shock (CS) is associated with high mortality. Current guidelines strongly recommend centralizing the care of these patients in high-complexity centres. We described the hospitalization-related economic cost and its main determinants in patients with CS in a high-complexity reference centre. METHODS AND RESULTS: This is a single-centre, retrospective study. All patients with CS (2015-17) were included. Hospitalization-related cost per patient was calculated by analytical accountability method, including hospital stay-related expenditures, interventions, and consumption of devices. Expenditure was expressed in 2018 euros. All-cause mortality during follow-up was registered. Ratio of cost per life-year gained (LYG) was also calculated. A total of 230 patients were included, with mean age of 63 years. In-hospital mortality was 88/230 (38.3%). Hospital stay was longer in patients surviving after the admission (21.7 vs. 7.5 days, P < 0.001). Total economic cost for the overall cohort was 3 947 118 (mean/patient 17 161). Most of this cost was attributable to hospital stay (81.1%). The rest of the expenditure was due to in-hospital procedures (13.1%) and the use of devices (5.8%). Most of hospital stay-related costs (79.8%) were due to Critical Care Unit stay. Mean follow-up was 651 days. Total LYG was 409.77 years for the whole series. The observed ratio of cost per LYG was 9632.52 /LYG. CONCLUSIONS: Management of CS in a reference centre is associated to a significant economic cost, but with a low ratio of cost per LYG. Most of this cost is attributable to hospital stay, specifically in critical care units.

BACKGROUND: Current guidelines recommend emergency surgical correction in patients with post infarction ventricular septal rupture (PIVSR), but patients with multiorgan failure are commonly managed conservatively because of high surgical risk. We assessed characteristics and outcomes of operated PIVSR patients with or without the use of short-term ventricular assist devices (ST-VADs). We also assessed the impact of a ST-VAD on the performance of surgery. METHODS: We retrospectively analysed all consecutive patients with PIVSR between January 2004 and May 2017. Baseline clinical characteristics, use of ST-VAD and performance of surgery during admission were assessed. The main outcome measured was in-hospital mortality. RESULTS: A total of 28 patients were included. Mean age was 69.2 years. Most patients (20/28, 71.4%) underwent surgical repair. ST-VADs were used in 11/28 patients (39.3%). This percentage progressively increased across the study period, from 22.2% (2/9) in 2004-2011 to 58.3% (7/12) in 2015-2017 (p=0.091). Patients undergoing ST-VAD use had poorer INTERMACS status, higher values of creatinine, lactate and alanine aminotransferase and lower left ventricular ejection fraction as compared with operated patients without support. In-hospital mortality did not differ according to the use of ST-VADs in operated patients (27.3% without ST-VAD vs. 22.2% with ST-VAD, p=0.604). All five patients undergoing early preoperative venoarterial extracorporeal membrane oxygenator support and delayed surgery survived at hospital discharge. CONCLUSIONS: ST-VAD use increased in patients with PIVSR. Despite a higher risk profile in operated patients undergoing ST-VAD use, mortality was not significantly different in these patients. Early preoperative venoarterial extracorporeal membrane oxygenation should be considered for very high risk PIVSR patients.

BACKGROUND: The prognostic role of diabetes mellitus (DM) in elderly patients with myocardial infarction-related cardiogenic shock (MI-CS) remains controversial. Little information exists about the impact of intensive cardiac care unit (ICCU) and revascularization on outcomes of elderly patients with MI-CS. We aimed to assess the prognostic impact of DM according to age in patients with MI-CS, and to analyze the impact ICCU management and revascularization on in-hospital mortality in MI-CS patients at older ages. METHODS: Discharge episodes with diagnosis of CS associated with MI were selected from the Spanish National Health System's Basic Data Set. Centers were classified according to their availability of ICCU. Main outcome measured was in-hospital mortality. RESULTS: A total of 23, 590 episodes of MI-CS were identified, of whom 12, 447 (52.8%) were in patients aged ≥ 75 years. The impact of DM on in-hospital mortality was different among age subgroups. While in younger patients, DM was associated to a higher mortality risk (0.52 vs. 0.47, OR = 1.12, 95% CI: 1.06-1.18, χ 2 < 0.001), this association became non-significant in older patients (0.76 vs. 0.81, χ 2 = 0.09). Adjusted mortality rate of MI-CS aged ≥ 75 years was lower in patients admitted to hospitals with ICCU (adjusted mortality rate: 74.2% vs. 77.7%, P < 0.001) and in patients undergoing revascularization (74.9% vs. 77.3%, P < 0.001). CONCLUSIONS: Prognostic impact of DM in patients with MI-CS was different according to age, with a significantly lower impact at older ages. The availability of ICCU and revascularization were associated with better outcomes in these complex patients.
ABSTRACT
AIMS: Anemia is associated with poorer outcomes in patients with acute coronary syndromes (ACS), but the magnitude of this association in elderly patients remains poorly understood. No study has assessed the prognostic impact of anemia according to frailty status in this setting. METHODS: The LONGEVO-SCA registry included unselected ACS patients aged at least 80 years. A geriatric assessment was performed during hospitalization, including frailty assessment using the FRAIL scale. Anemia was defined by the WHO criteria. We evaluated the impact of anemia on 6-month mortality according to the presence of frailty. RESULTS: A total of 517 patients were assessed. Mean age was 84.3 years, and a total of 236 patients (45.6%) had anemia. Patients with anemia had a higher prevalence of comorbidities and higher prevalence of frailty (30.6 vs. 22.3%, Pâ=â0.007). A total of 60 patients (12.1%) died at 6 months [40 with anemia (17.5%) and 20 without anemia (7.5%), Pâ=â0.001]. Anemia was independently associated with mortality at 6 months in the whole cohort (hazard ratio 2.28, 95% CI 1.13-457, Pâ=â0.021). The association of anemia and mortality was different according to frailty status, being significant in patients without frailty (hazard ratio 3.94, 95% CI 1.84-8.45, Pâ=â0.001), but not in frail patients (hazard ratio 1.17, 95% CI 0.53-2.57, Pâ=â0.705), (P value for interactionâ=â0.035). CONCLUSION: A high proportion of elderly patients with ACS have anemia, leading to a worse prognosis in the whole cohort. The association between anemia and mortality was especially significant in robust patients, whereas the poorer prognosis in frail patients was not modified by the presence of anemia.

BACKGROUND: Little information exists about the role of anemia in patients with acute coronary syndromes (ACS) admitted to Intensive Cardiac Care Units (ICCU). The aim of this study was to assess the prevalence of anemia and its impact on management and outcomes in this clinical setting. METHODS: All consecutive patients admitted to eight different ICCUs with diagnosis of non-ST segment elevation ACS (NSTEACS) were prospectively included. Anemia was defined as hemoglobin < 130 g/L in men and < 120 g/L in women. The association between anemia and mortality or readmission at six months was assessed by the Cox regression method. RESULTS: A total of 629 patients were included. Mean age was 66.6 years. A total of 197 patients (31.3%) had anemia. Coronary angiography was performed in most patients (96.2%). Patients with anemia were significantly older, with a higher prevalence of comorbidities, poorer left ventricle ejection fraction and higher GRACE score values. Patients with anemia underwent less often coronary angiography, but underwent more often intraaortic counterpulsation, non-invasive mechanical ventilation and renal replacement therapies. Both ICCU and hospital stay were significantly longer in patients with anemia. Both the incidence of mortality (HR = 3.36, 95% CI: 1.43-7.85, P = 0.001) and the incidence of mortality/readmission were significantly higher in patients with anemia (HR = 2.80, 95% CI: 2.03-3.86, P = 0.001). After adjusting for confounders, the association between anemia and mortality/readmission remained significant (P = 0.031). CONCLUSIONS: Almost one of three NSTEACS patients admitted to ICCU had anemia. Most patients underwent coronary angiography. Anemia was independently associated to poorer outcomes at 6 months.
ABSTRACT
INTRODUCTION AND OBJECTIVES: Current guidelines recommend centralizing the care of patients with cardiogenic shock in high-volume centers. The aim of this study was to assess the association between hospital characteristics, including the availability of an intensive cardiac care unit, and outcomes in patients with ST-segment elevation myocardial infarction (STEMI)-related cardiogenic shock (CS). METHODS: Discharge episodes with a diagnosis of STEMI-related CS between 2003 and 2015 were selected from the Minimum Data Set of the Spanish National Health System. Centers were classified according to the availability of a cardiology department, catheterization laboratory, cardiac surgery department, and intensive cardiac care unit. The main outcome measured was in-hospital mortality. RESULTS: A total of 19 963 episodes were identified. The mean age was 73.4±11.8 years. The proportion of patients with CS treated at hospitals with a catheterization laboratory and cardiac surgery department increased from 38.4% in 2005 to 52.9% in 2015 (P <.005). Crude- and risk-adjusted mortality rates decreased over time, from 82% to 67.1%, and from 82.7% to 66.8%, respectively (both P <.001). Coronary revascularization, either percutaneous or coronary artery bypass grafting, was independently associated with a lower mortality risk (OR, 0.29 and 0.25; both P <.001, respectively). Intensive cardiac care unit availability was associated with lower adjusted mortality rates (65.3%±7.9 vs 72±11.7; P <.001). CONCLUSIONS: The proportion of patients with STEMI-related CS treated at highly specialized centers increased while mortality decreased during the study period. Better outcomes were associated with the increased performance of revascularization procedures and access to intensive cardiac care units over time.

BACKGROUND: Diabetes mellitus predicts poorer outcomes in patients with acute coronary syndrome (ACS), but the magnitude of this association in patients at older ages remains controversial. METHODS: Data were extracted from the Codi Infart database. All consecutive patients with diagnosis of ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) between 2010 and 2015 were included. We assessed the impact of diabetes mellitus on 30-day and one-year mortality in patients aged less than and at least 75 years. RESULTS: A total of 12 792 cases were registered, of whom 3023 (23.6%) were aged at least 75 years. About 20% patients had previous diabetes mellitus diagnosis. Patients aged at least 75 years had higher prevalence of comorbidities, higher proportion of heart failure at admission, a more extensive coronary artery disease and significant delay to reperfusion (P < 0.001). Diabetes mellitus was associated with higher 30-day mortality both in young [odds ratio (OR) 1.97, 95% confidence interval (CI): 1.43-2.70] and in elderly patients (OR 1.43, 95% CI: 1.07-1.91). After adjusting for potential confounders, this association remained significant in young patients (OR 1.47, 95% CI: 1.00-2.16, P = 0.047), but not in the elderly (OR 1.14, P = 0.43). Likewise, a crude association between diabetes mellitus and one-year mortality was observed in both groups (young patients: HR = 1.93; 95% CI: 1.51-2.46; older patients: HR = 1.33; 95% CI: 1.08-1.64). However, after adjusting for potential confounders, this association remained significant in younger patients (HR = 1.46; 95% CI: 1.13-1.89; P < 0.001), but not in the elderly (HR = 1.16; P = 0.17). CONCLUSION: A significant proportion of these nonselected patients with STEMI had previous diabetes mellitus. The association between diabetes mellitus and outcomes is different according to age.

BACKGROUND: We aimed to assess the impact of implementation of reperfusion networks, the type of hospital and specialty of the treating physician on the management and outcomes of ST segment elevation myocardial infarction in patients aged ⩾75 years. METHODS: We analysed data from the Minimum Basic Data Set of the Spanish public health system, assessing hospital discharges between 2004 and 2013. Discharges were distributed in three groups depending on the clinical management: percutaneous coronary intervention, thrombolysis or no reperfusion. Primary outcome measure was all cause in-hospital mortality. For risk adjustment, patient comorbidities were identified for each index hospitalization. RESULTS: We identified 299,929 discharges, of whom 107,890 (36%) were in-patients aged ⩾75 years. Older patients had higher prevalence of comorbidities, were less often treated in high complexity hospitals and were less frequently managed by cardiologists ( p<0.001). Both percutaneous coronary intervention and fibrinolysis were less often performed in elderly patients ( p<0.001). A progressive increase in the rate of percutaneous coronary intervention was observed in the elderly across the study period (from 17% in 2004 to 45% in 2013, p<0.001), with a progressive reduction of crude mortality (from 23% in 2004 to 19% in 2013, p<0.001). Adjusted analysis showed an association between being treated in high complexity hospitals, being treated by cardiologists and lower in-hospital mortality ( p <0.001). CONCLUSIONS: Elderly patients with ST segment elevation myocardial infarction are less often managed in high complexity hospitals and less often treated by cardiologists. Both factors are associated with higher in-hospital mortality.

OBJECTIVES: Information on criteria for admitting elderly patients with acute coronary syndrome (ACS) to intensive care units (ICUs) is scarce. We aimed to describe factors associated with ICU admission in unselected older patients with ACS in Spain. MATERIAL AND METHODS: The prospective LONGEVO-SCA registry (Impact of Frailty and Other Geriatric Syndromes on the Management of and Mortality in Elderly Patients With Non-ST-segment Elevation Acute Coronary Syndrome) included unselected patients over the age of 80 years with non-ST-segment elevation SCA. A geriatric assessment of each patient was done in the hospital. Clinical outcomes at 6 months were analyzed. Bivariate logistic regression analysis was applied to identify ICU admission criteria. RESULTS: Of 508 patients with a mean age of 84.3 years, 150 (29.5%) were admitted to the ICU. The admitted patients were younger and more often had acute heart failure, elevated troponin levels, and poor left ventricular function. They also scored higher on the Acute Coronary Treatment and Intervention Outcomes Network-ICU (ACTION-ICU) and Global Registry of Acute Coronary Events (GRACE) risk scales. These patients had higher functional status scores and a lower prevalence of frailty and had more often undergone coronary angiography (P < .001). No differences in hospital mortality or outcomes at 6 months were detected between patients admitted or not admitted to ICUs. The following variables were independent predictors of ICU admission: no history of a previous episode of heart failure, an elevated troponin level on arrival, left ventricular dysfunction, high GRACE score and high Charlson Comorbidity Index, and absence of frailty. CONCLUSION: Around a third of elderly patients with non-ST-segment elevation ACS are admitted to an ICU. Admitted patients have a higher risk profile on arrival and a lower prevalence of geriatric syndromes.
OBJETIVO: La información sobre los condicionantes de ingreso en unidades de críticos (UC) de pacientes ancianos con síndrome coronario agudo (SCA) es escasa. El objetivo de este estudio fue describir los factores asociados al ingreso en UC en una serie de ancianos no seleccionados con SCA en España. METODO: El registro LONGEVO-SCA incluyó prospectivamente pacientes ≤ 80 años con SCA sin elevación del segmento ST (SCASEST), realizándose una valoración geriátrica intrahospitalaria y analizándose la evolución clínica a los 6 meses. Se analizaron los condicionantes de ingreso en UC mediante regresión logística binaria. RESULTADOS: De un total de 508 pacientes (edad media 84,3 años), 150 (29,5%) fueron ingresados en UC. Los pacientes ingresados en UC presentaban menor edad, mayor proporción de insuficiencia cardíaca aguda, troponina positiva y peor función ventricular izquierda, así como puntuaciones superiores en las escalas de riesgo GRACE y ACTION-ICU. Estos pacientes presentaban, asimismo, una mejor situación funcional y una menor prevalencia de fragilidad, y fueron sometidos a coronariografía con mayor frecuencia (p < 0,001). No se apreciaron diferencias en mortalidad hospitalaria ni evolución a los 6 meses entre ambos grupos. Los predictores independientes de ingreso en UC fueron la ausencia de insuficiencia cardíaca previa, troponina positiva al ingreso, disfunción ventricular izquierda, valores elevados en la escala GRACE y en el índice de Charlson, y ausencia de fragilidad. CONCLUSIONES: Alrededor de un tercio de los ancianos con SCASEST son ingresados en UC. Los pacientes ingresados en UC presentan mayor perfil de riesgo al ingreso y menor prevalencia de síndromes geriátricos.

INTRODUCTION: Ticagrelor and prasugrel are recommended as first line therapy in patients with acute coronary syndromes (ACS). However, patients with anemia are commonly treated with clopidogrel in routine clinical practice. The RENAMI registry (REgistry of New Antiplatelet therapy in patients with acute Myocardial Infarction) included ACS patients treated with prasugrel or ticagrelor at hospital discharge. The aim of this study was to analyze the prevalence of anemia and characteristics and outcomes of these patients according to anemia status. METHODS: Consecutive patients with ACS from 11 centers were included. All patients underwent percutaneous coronary intervention (PCI). Anemia was defined as hemoglobin <130â¯g/L in men and <120â¯g/L in women. The incidence of ischemic and bleeding events and all-cause mortality were assessed at one year. RESULTS: From 4424 patients included, 405 (9.2%) fulfilled criteria of anemia. Patients with anemia were significantly older, had a higher prevalence of peripheral artery disease, previous bleeding and renal disfunction and higher bleeding risk (PRECISE-DAPT scoreâ¯≥â¯25: 37.3% vs 18.8%, pâ¯<â¯0.001) The incidence of BARC 3/5 bleeding was moderately higher in patients with anemia (5.4% vs 1.5%, pâ¯=â¯0.001). The incidence of stent thrombosis or reinfarction was not significantly different according to anemia status. Anemia was independently associated with mortality (HR 1.73; 95% CI 1.03-2.91, pâ¯=â¯0.022). CONCLUSIONS: A not negligible proportion of patients treated with ticagrelor or prasugrel met criteria for anemia. Anemia was an independent predictor of mortality. Despite their higher bleeding risk profile, patients with anemia had an acceptable rate of bleeding.
