RESUMO
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.

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.
RESUMO
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.
RESUMO
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.

PURPOSE: To obtain initial data on the effect of different levels of targeted temperature management (TTM) in out-of-hospital cardiac arrest (OHCA). METHODS: We designed a multicentre pilot trial with 1:1:1 randomization to either 32 °C (n = 52), 33 °C (n = 49) or 34 °C (n = 49), via endovascular cooling devices during a 24-h period in comatose survivors of witnessed OHCA and initial shockable rhythm. The primary endpoint was the percentage of subjects surviving with good neurologic outcome defined by a modified Rankin Scale (mRS) score of ≤ 3, blindly assessed at 90 days. RESULTS: At baseline, different proportions of patients who had received defibrillation administered by a bystander were assigned to groups of 32 °C (13.5%), 33 °C (34.7%) and 34 °C (28.6%; p = 0.03). The percentage of patients with an mRS ≤ 3 at 90 days (primary endpoint) was 65.3, 65.9 and 65.9% in patients assigned to 32, 33 and 34 °C, respectively, non-significant (NS). The multivariate Cox proportional hazards model identified two variables significantly related to the primary outcome: male gender and defibrillation by a bystander. Among the 43 patients who died before 90 days, 28 died following withdrawal of life-sustaining therapy, as follows: 7/16 (43.8%), 10/13 (76.9%) and 11/14 (78.6%) of patients assigned to 32, 33 and 34 °C, respectively (trend test p = 0.04). All levels of cooling were well tolerated. CONCLUSIONS: There were no statistically significant differences in neurological outcomes among the different levels of TTM. However, future research should explore the efficacy of TTM at 32 °C. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov unique identifier: NCT02035839 ( http://clinicaltrials.gov ).

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.

BACKGROUND: A poor ability of recommended risk scores for predicting in-hospital bleeding has been reported in elderly patients with acute coronary syndromes (ACS). No study assessed the prediction of post-discharge bleeding in the elderly. The new BleeMACS score (Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome), was designed to predict post-discharge bleeding in ACS patients. We aimed to assess the predictive ability of the BleeMACS score in elderly patients. METHODS: We assessed the incidence and characteristics of severe bleeding after discharge in ACS patients aged ≥ 75 years. Bleeding was defined as any intracranial bleeding or bleeding leading to hospitalization and/or red blood transfusion, occurring within the first year after discharge. We assessed the predictive ability of the BleeMACS score according to age by Fine-Gray proportional hazards regression analysis, calculating receiver-operating characteristic (ROC) curves and the area under the ROC curves (AUC). RESULTS: The BleeMACS registry included 15,401 patients of whom 3,376/15,401 (21.9%) were aged ≥ 75 years. Elderly patients were more commonly treated with clopidogrel and less often treated with ticagrelor or prasugrel. Of 3,376 elderly patients, 190 (5.6%) experienced post-discharge bleeding. The incidence of bleeding was moderately higher in elderly patients (hazard ratio [HR], 2.31, 95% confidence interval [CI], 1.92-2.77). The predictive ability of the BleeMACS score was moderately lower in elderly patients (AUC, 0.652 vs. 0.691, p = 0.001). CONCLUSION: Elderly patients with ACS had a significantly higher incidence of post-discharge bleeding. Despite a lower predictive ability in older patients, the BleeMACS score exhibited an acceptable performance in these patients.

INTRODUCTION AND OBJECTIVE: Anemia is a common comorbidity in patients with acute coronary syndromes (ACS), and is associated with higher risk for both bleeding and ischemic complications. We aimed to assess the predictive ability of bleeding risk scores (Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHA guidelines [CRUSADE], Mehran and Acute Coronary Treatment and Intervention Outcomes Network [ACTION]) in ACS patients with anemia. METHODS: All consecutive ACS patients were prospectively included. The primary outcome was in-hospital major bleeding according to the CRUSADE, Mehran and ACTION definitions. Anemia was defined as hemoglobin <130 g/l in men and <120 g/l in women. The predictive ability of the bleeding risk scores was assessed by binary logistic regression, calculating receiver operating characteristic (ROC) curves and their corresponding area under the curve (AUC). RESULTS: We included 2255 patients, mean age 62.4 years. Anemia was present in 550 patients (24.4%). Patients with anemia had a significantly higher prevalence of comorbidities. The three bleeding risk scores adequately predicted major bleeding in the whole cohort. No significant differences were observed regarding the predictive ability of each of the scores in patients with and without anemia (CRUSADE: AUC 0.73 without anemia vs. 0.74 with anemia, p=0.913; ACTION: AUC 0.68 without anemia vs. 0.73 with anemia, p=0.353; Mehran: AUC 0.69 without anemia vs. 0.61 with anemia, p=0.210). Only the Mehran score showed significantly lower predictive ability in patients with hemoglobin <11 g/dl (AUC 0.51, p=0.044). CONCLUSIONS: Anemia was a common comorbidity in patients with ACS from our series. Currently available bleeding risk scores showed an adequate predictive ability in patients with mild anemia.

BACKGROUND AND OBJECTIVE: Little information exists about the prognostic impact of body mass index (BMI) in the elderly with acute coronary syndromes (ACS). We aimed to prospectively assess the association between BMI and midterm mortality in consecutive elderly patients with ACS. PATIENTS AND METHOD: We included consecutive ACS patients aged 75 years or older admitted to the Coronary Care Unit. Patients were stratified into 5 BMI subgroups (<20, 20-24.9, 25-29.9, 30-35, > 35 kg/m(2)). Primary endpoint was overall midterm mortality. Analyses were performed by Cox regression method. RESULTS: During the study period 600 patients were admitted, of whom 579 had known BMI values. Low weight patients (BMI<20 kg/m(2)) were older, with higher prevalence of vasculopathy and lower creatinine clearance. Median follow up was 315 days. Patients with BMI< 20 kg/m(2) had higher mortality as compared to the rest of groups. Adjusted analysis showed an attenuation of these differences, while maintaining significance for the groups of BMI 20-24.9 and 30-35 kg/m(2). CONCLUSIONS: The association between BMI and mortality was mainly due to worse prognosis in low weight patients. Prospective assessment of comorbidities and other variables linked to ageing should contribute to better understand the association between BMI and mortality.

INTRODUCTION AND OBJECTIVES: The incidence of acute coronary syndromes is high in the elderly population. Bleeding is associated with a poorer prognosis in this clinical setting. The available bleeding risk scores have not been validated specifically in the elderly. Our aim was to assess predictive ability of the most important bleeding risk scores in patients with acute coronary syndrome aged ≥ 75 years. METHODS: We prospectively included consecutive acute coronary syndromes patients. Baseline characteristics, laboratory findings, and hemodynamic data were collected. In-hospital bleeding was defined according to CRUSADE, Mehran, ACTION, and BARC definitions. CRUSADE, Mehran, and ACTION bleeding risk scores were calculated for each patient. The ability of these scores to predict major bleeding was assessed by binary logistic regression, receiver operating characteristic curves, and area under the curves. RESULTS: We included 2036 patients, with mean age of 62.1 years; 369 patients (18.1%) were ≥ 75 years. Older patients had higher bleeding risk (CRUSADE, 42 vs 22; Mehran, 25 vs 15; ACTION, 36 vs 28; P<.001) and a slightly higher incidence of major bleeding events (CRUSADE bleeding, 5.1% vs 3.8%; P=.250). The predictive ability of these 3 scores was lower in the elderly (area under the curve, CRUSADE: 0.63 in older patients, 0.81 in young patients; P=.027; Mehran: 0.67 in older patients, 0.73 in younger patients; P=.340; ACTION: 0.58 in older patients, 0.75 in younger patients; P=.041). CONCLUSIONS: Current bleeding risk scores showed poorer predictive performance in elderly patients with acute coronary syndromes than in younger patients.

INTRODUCTION AND OBJECTIVES: The prognostic value of chronic total occlusion in nonculprit coronary arteries in patients with myocardial infarction undergoing primary angioplasty remains controversial. Several publications have described different methodologies and conflicting findings. In addition, causes of death were not reported. Our aim is to analyze the prognostic impact of chronic total occlusion in nonculprit coronary arteries and the role of left ventricular ejection fraction in this analysis. METHODS: Prospective inclusion of consecutive patients with ST-segment elevation myocardial infarction who underwent primary angioplasty. We recorded baseline characteristics, in-hospital clinical course, and mortality and its causes during follow-up. We assessed the impact of chronic total occlusion on mortality using Cox regression analysis. RESULTS: Chronic total occlusion in nonculprit arteries was present in 125 of 1176 patients (10.6%); in 79 of these 125 patients, chronic total occlusion was present in the proximal segments. The mean follow-up was 339 days; 64 (5.8%) patients died during the first 6 months. Patients with chronic total occlusions had more comorbidities, poorer ventricular function, and higher mortality (hazard ratio=2.79; 95% confidence interval, 1.71-4.56). Chronic total occlusion was also associated with noncardiac death (hazard ratio=3.83; 95% confidence interval, 2.10-7.01). Chronic total occlusion in proximal segments was associated with both cardiac (hazard ratio=3.22; 95% confidence interval, 1.42-7.30) and noncardiac deaths (hazard ratio=3.43; 95% confidence interval, 1.67-7.06). The multivariate analysis performed without including left ventricular ejection fraction showed a significant association between chronic total occlusion and mortality. However, when left ventricular ejection fraction was included in the analysis, this association was nonsignificant (hazard ratio=1.76; 95% confidence interval, 0.85-3.65; P=.166). CONCLUSIONS: Chronic total occlusion in this clinical setting identified patients at higher risk with more comorbidities and higher mortality, but did not behave as an independent predictor of mortality when left ventricular ejection fraction was included in the analysis.

BACKGROUND: Percutaneous coronary intervention (PCI) improves prognosis in patients with acute coronary syndromes (ACS) reducing ischaemic complications and the development of heart failure, thus potentially changing invasive mechanical ventilation (IMV) requirements. Little information exists about patients with ACS requiring IMV in the current era. We aimed to analyze IMV requirements and characteristics of ACS patients treated under current recommendations (including a high rate of PCI). METHODS: Baseline characteristics, indications for IMV, management and in-hospital and mid-term clinical course were analyzed prospectively in a consecutive series of patients with ACS admitted to a tertiary care hospital. RESULTS: We included 1821 patients, of which 106 (5.8%) required IMV. Mean follow-up was 347 days. PCI was performed in 84% of cases. Patients with IMV had more comorbidities, worse left ventricular function and more unstable hemodynamic parameters on admission. In-hospital mortality in patients requiring IMV was 29%. These patients also had higher mid-term mortality (hazard ratio (HR) 6.58; 95% confidence interval (CI) 4.49-9.64; p 0.001). The most common indication for IMV was cardiopulmonary arrest (CA) (65; 61%), followed by pulmonary oedema (27; 26%) and shock (14; 13.2%). Patients with CA were younger, with better hemodynamic parameters at admission, more favourable coronary anatomy and higher rates of PCI. There were no significant differences in overall mortality between the three groups. The main cause of death in CA patients was persistent vegetative state. CONCLUSIONS: Mortality in patients with ACS requiring IMV remained high despite a high rate of PCI. Baseline characteristics, management and clinical course were different according to the reason for IMV. The most common cause for IMV requirement was CA.

INTRODUCTION: The CRUSADE bleeding risk score (CBRS) accurately predicts major bleeding in non-ST segment elevation myocardial infarction NSTEMI patients. However, little information exists about its application in ST segment elevation myocardial infarction STEMI. We aimed to assess the ability of CBRS to predict in-hospital major bleeding in STEMI patients undergoing primary percutaneous coronary intervention (PPCI). MATERIALS AND METHODS: We prospectively analyzed consecutive STEMI patients undergoing PPCI. Baseline characteristics, in-hospital complications and mid term mortality were recorded. Major bleeding was defined by the CRUSADE definition. Predictive ability of the CBRS was assessed by logistic regression method and the area under the ROC curve (AUC). RESULTS: We included 1064 patients (mean age 63years). Mean CBRS value was 24. Most of patients (740/1064 (69.6%)) were in the two lowest risk quintiles of CBRS. Incidence of in-hospital major bleeding was 33/1064 (3.1%). The rates of in-hospital bleeding across the quintiles of risk groups were 0.4% (very low risk), 2.6% (low), 4.6% (moderate), 7.2% (high), and 13.4% (very high) (p 0.001). AUC was 0.80 (95% CI 0.73-0.87 p 0.001). In patients with radial access angiography (n=621) AUC was 0.81 (95% CI: 0.65-0.97). Mean follow up was 344days. Patients with bleeding events had higher mortality during follow up (HR 6.91; 95% CI 3.72-12.82; p 0.001). CONCLUSIONS: Our patients had a significantly lower bleeding risk as compared to CRUSADE NSTEMI population. CBRS accurately predicted major in-hospital bleeding in this different clinical scenario, including patients with radial artery approach.
