Burden of Recurrent Hospitalizations Following an Admission for Acute Heart Failure: Preserved Versus Reduced Ejection Fraction.

Abstract Introduction and objectives Heart failure with preserved ejection fraction and reduced ejection fraction share a high mortality risk. However, differences in the rehospitalization burden over time between these 2 entities remains unclear. Methods We prospectively included 2013 consecutive patients discharged for acute heart failure. Of these, 1082 (53.7%) had heart failure with preserved ejection fraction and 931 (46.2%) had heart failure with reduced ejection fraction. Cox and negative binomial regression methods were used to evaluate the risks of death and repeat hospitalizations, respectively. Results At a median follow-up of 2.36 years (interquartile range: 0.96-4.65), 1018 pat…

Usefulness of Clinical Data and Biomarkers for the Identification of Frailty After Acute Coronary Syndromes

Abstract Background Frailty predicts mortality after acute coronary syndrome (ACS). The standard frailty scales, such as the Fried score, consist of a variety of questionnaires and physical tests. Our aim was to investigate easily available clinical data and blood markers to predict frailty at discharge, in elderly patients after ACS. Methods A total of 342 patients older than 65 years, survivors after ACS, were included. A high number of clinical variables were collected. In addition, blood markers potentially linked to frailty and related to the processes of inflammation, coagulation, hormonal dysregulation, nutrition, renal dysfunction, and heart dysfunction were determined. Frailty was …

Long-term prognostic value of a comprehensive assessment of cardiac magnetic resonance indexes after an ST-segment elevation myocardial infarction.

Abstract Introduction and objectives A variety of cardiac magnetic resonance indexes predict mid-term prognosis in ST-segment elevation myocardial infarction patients. The extent of transmural necrosis permits simple and accurate prediction of systolic recovery. However, its long-term prognostic value beyond a comprehensive clinical and cardiac magnetic resonance evaluation is unknown. We hypothesized that a simple semiquantitative assessment of the extent of transmural necrosis is the best resonance index to predict long-term outcome soon after a first ST-segment elevation myocardial infarction. Methods One week after a first ST-segment elevation myocardial infarction we carried out a comp…

Changes in myocardial iron content following administration of intravenous iron (Myocardial‐IRON): Study design

Treatment with intravenous ferric carboxymaltose (FCM) has been shown to improve symptoms, functional capacity, and quality of life in patients with heart failure and iron deficiency. However, the underlying mechanisms for these beneficial effects remain undetermined. The aim of this study is to quantify cardiac magnetic resonance changes in myocardial iron content after administration of intravenous FCM in patients with heart failure and iron deficiency and contrast them with parameters of heart failure severity. This is a multicenter, double-blind, randomized study. Fifty patients with stable symptomatic heart failure, left ventricular ejection fraction <50%, and iron deficiency will be r…

Randomized comparison between the invasive and conservative strategies in comorbid elderly patients with non-ST elevation myocardial infarction.

Abstract Background Comorbid elderly patients with non-ST-elevation myocardial infarction (non-STEMI) are underrepresented in randomized trials and undergo fewer cardiac catheterizations according to registries. Our aim was to compare the conservative and invasive strategies in these patients. Methods Randomized multicenter study, including 106 patients (January 2012–March 2014) with non-STEMI, over 70 years and with comorbidities defined by at least two of the following: peripheral artery disease, cerebral vascular disease, dementia, chronic pulmonary disease, chronic renal failure or anemia. Patients were randomized to invasive (routine coronary angiogram, n = 52) or conservative (coronar…

5877Comorbidity assessment for mortality risk stratification in elderly patients with acute coronary syndrome

Abstract Background The Charlson's is the most used comorbidity index. It comprises 19 comorbidities, some of which are infrequent in elderly patients with acute coronary syndrome (ACS), while some others are manifestations of cardiac disease rather than comorbidities. Purpose Our goal was to simplify comorbidity assessment in elderly non-ST-segment elevation ACS patients. Methods The study group consisted of 1 training (n=920, 76±7 years) and 1 testing (n=532; 84±4 years) cohorts. The end-point was all-cause mortality at 1-year follow-up. Comorbidities were assessed selecting those medical disorders other than cardiac disease that were independently associated with mortality by multivariab…

Plasma neutrophil gelatinase-associated lipocalin and long-term mortality in patients with acute heart failure and normal renal function

Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as a renal tubular marker for early renal dysfunction [1]. Recent studies highlighted its role in predicting acute kidney injury (AKI) and clinical outcomes in a wide range of cardiovascular diseases [2], [3], [4] and [5]. However, in heart failure (HF), conflicting results have been reported [4], [5], [6] and [7] and some ambiguities still prevail about the prognostic utility of NGAL beyond standard prognosticators and traditional renal biomarkers. We aimed to evaluate the independent ability of serum NGAL for predicting long-term mortality in patients admitted for acute HF (AHF). We prospectively enrolled 206 patients consecuti…

Inspiratory Muscle Training and Functional Electrical Stimulation for Treatment of Heart Failure With Preserved Ejection Fraction: The TRAINING-HF Trial

Introduction and objectives: Despite the prevalence of heart failure with preserved ejection fraction (HFpEF), there is currently no evidence-based effective therapy for this disease. This study sought to evaluate whether inspiratory muscle training (IMT), functional electrical stimulation (FES), or a combination of both (IMT + FES) improves 12- and 24-week exercise capacity as well as left ventricular diastolic function, biomarker profile, and quality of life in HFpEF. Methods: A total of 61 stable symptomatic patients (New York Heart Association II-III) with HFpEF were randomized (1:1:1:1) to receive a 12-week program of IMT, FES, or IMT + FES vs usual care. The primary endpoint of the st…

Usefulness of delta troponin for diagnosis and prognosis assessment of non-ST-segment elevation acute chest pain.

The additional diagnostic and prognostic information provided by delta high-sensitivity troponin T (hs-cTnT) in patients with acute chest pain and hs-cTnT elevation remains unclear.The study group consisted of 601 patients presenting at the emergency department with non-ST-segment elevation acute chest pain and hs-cTnT elevation after two determinations (admission and within the first six hours). Maximum hs-cTnT and delta hs-cTnT (absolute or percentage change between the two measurements) were considered. Cutoff values were optimized using the quartile distribution for the endpoints. The endpoints were diagnostic (significant stenosis in the coronary angiogram) and prognostic (death or rec…

High-sensitivity troponin T and the risk of recurrent readmissions after hospitalization for acute heart failure

Abstract Objectives High-sensitivity troponin is a biomarker of myocardial damage and is associated with a greater risk of mortality and disease progression in patients with acute heart failure (AHF). However, its relationship with the risk of future readmissions is less known. The aim of this study was to assess the association between ultrasensitive troponin T (TnT-us) values in patients with AHF and the risk of recurrent readmissions in the follow-up. Methods We prospectively included a cohort of 621 consecutive patients with AHF, excluding those patients with acute coronary syndrome. We measured the TnT-us levels obtained during the first medical contact in the emergency department. The…

Iron deficiency and risk of early readmission following a hospitalization for acute heart failure

Factors associated with plasma antigen carbohydrate 125 and amino-terminal pro-B-type natriuretic peptide concentrations in acute heart failure

Background: Plasma amino-terminal pro-B-type natriuretic peptide and antigen carbohydrate 125 levels are positively associated with a higher risk of adverse clinical outcomes in acute heart failure. As a proxy of congestion, antigen carbohydrate 125 has also been proposed as a right-sided heart failure marker. Thus, we aimed to determine in this population the main factors – including echocardiographic right-sided heart failure parameters – associated with antigen carbohydrate 125 and amino-terminal pro-B-type natriuretic peptide. Methods and results: We prospectively included 2949 patients admitted with acute heart failure. Amino-terminal pro-B-type natriuretic peptide and antigen carbohy…

Randomized Comparison of Exercise Intervention Versus Usual Care in Older Adult Patients with Frailty After Acute Myocardial Infarction.

Abstract Background Older adult patients with frailty are rarely involved in rehabilitation programs after myocardial infarction. Our aim was to investigate the benefits of exercise intervention in these patients. Methods A total of 150 survivors after acute myocardial infarction, ≥70 years and with pre-frailty or frailty (Fried scale ≥1 points), were randomized to control (n = 77) or intervention (n = 73) groups. The intervention consisted of a 3-month exercise program, under physiotherapist supervision, followed by an independent home-based program. The main outcome was frailty (Fried scale) at 3 months and 1 year. Secondary endpoints were clinical events (mortality or any readmission) at…

Predictors of cardiovascular magnetic resonance-derived microvascular obstruction on patient admission in STEMI

Early stratification of patients according to the risk for developing microvascular obstruction (MVO) after ST-segment elevation myocardial infarction (STEMI) is desirable. We aimed to identify predictors of cardiovascular magnetic resonance (CMR)-derived MVO from clinical+ECG, laboratory and angiographic parameters available on admission.Characteristics available on admission were documented in 97 STEMI patients referred for primary angioplasty. MVO was determined using contrast-enhanced CMR.MVO was present in 44 patients (45%). The C-statistic for predicting MVO was: clinical+ECG (.832), laboratory (.743), and angiographic parameters (.669). Adding laboratory to clinical+ECG information d…

CA125 outperforms NT-proBNP in acute heart failure with severe tricuspid regurgitation.

In acute heart failure (AHF) with right ventricular dysfunction, the roles of amino-terminal pro-brain natriuretic peptide (NT-proBNP) and carbohydrate antigen 125 (CA125) are poorly understood, and functional tricuspid regurgitation (TR) severity is thought to indicate a poor prognosis. We examined the prognostic abilities of NT-proBNP and CA125 according to TR status among patients with AHF.TR severity was assessed during index hospitalization (108 ± 24 h after admission) and classified as none/trivial, mild, moderate, or severe. Multivariable Cox regression analysis was performed to assess how pre-discharge CA125 and NT-proBNP were associated with long-term all-cause mortality relative t…

Lipoprotein(a) and long-term recurrent infarction after an episode of ST-segment elevation acute myocardial infarction

Background In established ischemic heart disease, the relationship between lipoprotein(a) and new cardiovascular events showed contradictory results. Our aim was to assess the relationship between lipoprotein(a) and very long-term recurrent myocardial infarction (MI) after an index episode of ST-segment elevation acute myocardial infarction (STEMI). Methods We included 435 consecutive STEMI patients discharged from October 2000 to June 2003 in a single teaching center. The relationship between lipoprotein(a) at discharge and recurrent MI was evaluated through negative binomial regression and Cox regression analysis. Results The mean age was 65 years (55-74 years), 25.5% were women, 34.7% we…

Frailty Tools for Assessment of Long-term Prognosis After Acute Coronary Syndrome

Objective: To evaluate the 5 components of the Fried frailty phenotype (self-reported unintentional weight loss, physical activity questionnaire, gait speed, grip strength, and self-reported exhaustion) for long-term outcomes in elderly survivors of acute coronary syndrome. Methods: A total of 342 consecutive patients (from October 1, 2010, to February 1, 2012) were included. The 5 components of the Fried score and albumin concentration, as malnutrition index, were assessed before hospital discharge. Patients were followed up until April 2020 (median follow-up, 8.7 years). The end point was postdischarge all-cause mortality. Results: Mean ± SD age was 77±7 years and mean ± SD Fried score wa…

Cell-free DNA and Microvascular Damage in ST-segment Elevation Myocardial Infarction Treated With Primary Percutaneous Coronary Intervention.

INTRODUCTION AND OBJECTIVES Cell-free DNA (cfDNA) in ST-segment elevation myocardial infarction might originate from hyperactivated leukocytes at the coronary lesion. Our aim was to investigate the relationship between cfDNA and coronary reperfusion. METHODS We studied 116 patients treated with primary angioplasty using thrombus aspiration. Coronary (during aspiration) and peripheral (at the end of the procedure) blood samples were drawn for cfDNA, as well as high-sensitivity troponin T and myeloperoxidase quantification. The primary endpoint was no ST-segment resolution (STR) (≥ 70%) and the secondary endpoint was lack of final Thrombolysis In Myocardial Infarction flow 3 (TIMI 3). RESULTS…

Echocardiographic pulmonary artery pressure estimation and heart failure rehospitalization burden in patients with acute heart failure

Abstract Pulmonary hypertension (PH) is a strong predictor of mortality in patients with heart failure (HF). However, the relationship between PH, through echocardiographic pulmonary artery pressure (PASP) estimation, and the risk of HF rehospitalizations remains unclear. Methods We prospectively included 2343 consecutive patients discharged for acute heart failure (AHF). PH was estimated by echocardiography through PASP determination during the index admission. Patients were categorized as follows across PASP: non-measurable, normal (≤35mmHg), mild (36–45mmHg), moderate (46–60mmHg), or severe PH (>60mmHg). Negative binomial regression method was used to evaluate the association between PAS…

P3543Rehospitalization burden in heart failure with mid-range ejection fraction and morbidity burden. Is it a distinct phenotype?

Abstract Heart failure with mid-range ejection fraction (HFmrEF) has been recognized as a distinct HF phenotype, but wether patients on this category fare worse, similarly, or better than those with HF with reduced EF (HFrEF) or preserved EF (HFpEF) in terms of rehospitalization risk over time remains unclear. We therefore sought to characterize the mordibity burden of HFmrEF patients by evaluating the risk of recurrent hospitalizations following an admission for acute HF. Methods We prospectively included 2,961 consecutive patients discharged for acute HF in our institution from 2004 to 2017. Patients were categorized according to their ejection fraction (EF) obtained by an echocardiograph…

Prognostic Value of Geriatric Conditions Beyond Age After Acute Coronary Syndrome

The aim of the present study was to investigate the prognostic value of geriatric conditions beyond age after acute coronary syndrome. This was a prospective cohort design including 342 patients (from October 1, 2010, to February 1, 2012) hospitalized for acute coronary syndrome, older than 65 years, in whom 5 geriatric conditions were evaluated at discharge: frailty (Fried and Green scales), comorbidity (Charlson and simple comorbidity indexes), cognitive impairment (Pfeiffer test), physical disability (Barthel index), and instrumental disability (Lawton-Brody scale).

Diuretic Strategies in Acute Heart Failure and Renal Dysfunction: Conventional vs Carbohydrate Antigen 125-guided Strategy. Clinical Trial Design

Abstract Introduction and objectives The optimal treatment of patients with acute heart failure (AHF) and cardiorenal syndrome type 1 (CRS-1) is far from being well-defined. Arterial hypoperfusion in concert with venous congestion plays a crucial role in the pathophysiology of CRS-I. Plasma carbohydrate antigen 125 (CA125) has emerged as a surrogate of fluid overload in AHF. The aim of this study was to evaluate the clinical usefulness of CA125 for tailoring the intensity of diuretic therapy in patients with CRS-1. Methods Multicenter, open-label, parallel clinical trial, in which patients with AHF and serum creatinine ≥ 1.4 mg/dL on admission will be randomized to: a) standard diuretic str…

Tricuspid Regurgitation and Mortality Risk Across Left Ventricular Systolic Function in Acute Heart Failure.

BACKGROUND Tricuspid regurgitation (TR) is a common echocardiographic finding that has been related to adverse outcome under various clinical scenarios. Nevertheless, evidence supporting its prognostic value in heart failure (HF) is scarce, and, in most cases, contradictory. We evaluated the association of TR grade with 1-year all-cause mortality in acute HF (AHF). METHODS AND RESULTS: We included 1,842 consecutive patients admitted for AHF. Mean age was 72.8±11.3 years, 51% were female and 45.5% had LVEF <50%. The severity of TR was graded in non-TR, mild (1), moderate (2), moderate-severe (3) and severe (4). At 1-year follow-up, 370 patients (20.1%) had died. In patients with LVEF ≥50%, a…

Undetectable high-sensitivity troponin in combination with clinical assessment for risk stratification of patients with chest pain and normal troponin at hospital arrival

Background Undetectable high-sensitivity cardiac troponin (hs-cTn) in a single determination upon admission may rule out acute coronary syndrome. We investigated undetectable hs-cTnT (&amp;lt;detection limit; &amp;lt;5 ng/l) together with clinical risk scores (GRACE, TIMI, HEART and a previously published simple score), for one-year outcomes in patients with chest pain and normal hs-cTnT (&amp;lt;99th percentile; &amp;lt;14 ng/l) upon admission. Methods This study was a retrospective design involving 2254 consecutive patients (July 2016–November 2017). The primary endpoint was one-year death or acute myocardial infarction; the secondary endpoint added unstable angina requiring revasculariz…

Percutaneous coronary intervention and recurrent hospitalizations in elderly patients with non ST-segment acute coronary syndrome: The role of frailty

Growth differentiation factor 15 and geriatric conditions in acute coronary syndrome

Abstract Background Growth differentiation factor 15 (GDF-15) is a marker of cell senescence. Age is a well-known determinant of GDF-15 levels, yet no study has analyzed the relationship between geriatric conditions and GDF-15. We hypothesize that geriatric conditions reflecting biological age might be stronger determinants of GDF-15 than chronological age in elderly patients with acute coronary syndrome. Methods A total of 208 patients (mean age = 78.3 ± 7.0 years) were included. Prior to discharge, a thorough geriatric assessment was performed and GDF-15 measured. Predictors of GDF-15 (transformed by its natural logarithm) were determined with linear regression. Furthermore, Cox regressio…

Functional Mitral Regurgitation Predicts Short-Term Adverse Events in Patients With Acute Heart Failure and Reduced Left Ventricular Ejection Fraction

Functional mitral regurgitation (FMR) is a common finding in patients with acute heart failure (AHF) and reduced left ventricular ejection fraction (heart failure and reduced ejection fraction [HFrEF]). However, its clinical impact remains unclear. We aimed to evaluate the association between the severity of FMR after clinical stabilization and short-term adverse outcomes after a hospitalization for AHF. We prospectively included 938 consecutive patients with HFrEF discharged after a hospitalization for AHF, after excluding those with organic valve disease, congenital heart disease, or aortic valve disease. FMR was assessed semiquantitatively by color Doppler analysis of the regurgitant jet…

Right ventricular function and iron deficiency in acute heart failure

Abstract Aims Iron deficiency (ID) is a frequent finding in patients with chronic and acute heart failure (AHF) along the full spectrum of left ventricular ejection fraction (LVEF). Iron deficiency has been related to ventricular systolic dysfunction, but its role in right ventricular function has not been evaluated. We sought to evaluate whether ID identifies patients with greater right ventricular dysfunction in the setting of AHF. Methods and results We prospectively included 903 patients admitted with AHF. Right systolic function was evaluated by tricuspid annular plane systolic excursion (TAPSE) and the ratio TAPSE/pulmonary artery systolic pressure (TAPSE/PASP). Iron deficiency was de…

Relation of Low Lymphocyte Count to Frailty and its Usefulness as a Prognostic Biomarker in Patients &gt;65 Years of Age With Acute Coronary Syndrome

Low lymphocyte count, as a marker of inflammation and immunosuppression, may be useful for identifying frail patients. In this work, we aimed to evaluate the association between low-relative lymphocyte count (Lymph%) and frailty status in patients >65 years old with acute coronary syndromes (ACS), and whether Lymph% is associated with morbimortality beyond standard prognosticators and frailty. In this prospective observational study, we included 488 hospital survivors of an episode of an ACS >65 years old. Total and differential white blood cells and frailty status were assessed at discharge. Frailty was evaluated using the Fried score at discharge and defined as Fried≥3. The independent as…

CA125-Guided Diuretic Treatment Versus Usual Care in Patients With Acute Heart Failure and Renal Dysfunction

BACKGROUND: The optimal diuretic treatment strategy for patients with acute heart failure and renal dysfunction remains unclear. Plasma carbohydrate antigen 125 (CA125) is a surrogate of fluid overload and a potentially valuable tool for guiding decongestion therapy. The aim of this study was to determine if a CA125-guided diuretic strategy is superior to usual care in terms of short-term renal function in patients with acute heart failure and renal dysfunction at presentation. METHODS: This multicenter, open-label study randomized 160 patients with acute heart failure and renal dysfunction into 2 groups (1:1). Loop diuretics doses were established according to CA125 levels in the CA125-gui…

Length of stay and risk of very early readmission in acute heart failure

In patients admitted for acute heart failure (AHF), optimal length of stay (LOS) remains controversial. Longer hospitalizations are associated with worse prognosis, but little is known about short hospitalizations. The aim of this work was to evaluate the relationship between LOS and the risk of short-term readmission in patients discharged after a hospitalization for AHF.We included 2110 consecutive patients. The independent associations between LOS and unplanned 10, 15 and 30-day readmissions were evaluated by Cox regression analysis adjusted for competing events. LOS was categorized as LOS1: ≤4days, LOS2: 5-7days, LOS3: 8-10days, and LOS4:10days.The mean age was 73±11years and 52.6% exhi…

Frailty Scales for Prognosis Assessment of Older Adult Patients after Acute Myocardial Infarction

We aimed to compare the prognostic value of two different measures, the Fried’s Frailty Scale (FFS) and the Clinical Frailty Scale (CFS), following myocardial infarction (MI). We included 150 patients ≥ 70 years admitted from AMI. Frailty was evaluated on the day before discharge. The primary endpoint was number of days alive and out of hospital (DAOH) during the first 800 days. Secondary endpoints were mortality and a composite of mortality and reinfarction. Frailty was diagnosed in 58% and 34% of patients using the FFS and CFS scales, respectively. During the first 800 days 34 deaths and 137 admissions occurred. The number of DAOH decreased significantly with increasing scores of both FFS…

Comorbidity assessment for mortality risk stratification in elderly patients with acute coronary syndrome.

Background The Charlson's is the most used comorbidity index. It comprises 19 comorbidities, some of which are infrequent in elderly patients with acute coronary syndrome (ACS), while some others are manifestations of cardiac disease rather than comorbidities. Our goal was to simplify comorbidity assessment in elderly non-ST-segment elevation ACS patients. Methods The study group consisted of 1 training (n = 920, 76 ± 7 years) and 1 testing (n = 532; 84 ± 4 years) cohorts. The end-point was all-cause mortality at 1-year follow-up. Comorbidities were assessed selecting those medical disorders other than cardiac disease that were independently associated with mortality by multivariable analys…

Factor trefoil-3 y galectina-4 como nuevos candidatos para biomarcadores pronósticos en infarto de miocardio con elevación del segmento ST

Clinical Evaluation Versus Undetectable High-Sensitivity Troponin for Assessment of Patients With Acute Chest Pain.

Decision-making in acute chest pain remains challenging despite normal (below ninety-ninth percentile) high-sensitivity troponin (hs-cTn). Some studies suggest that undetectable hs-cTn, far below the ninety-ninth percentile, might rule out acute coronary syndrome. We investigated clinical data in comparison to undetectable hs-cTnT. The study comprised 682 patients (November 2010 to September 2011) presenting at the emergency department with chest pain and normal hs-cTnT (14 ng/l). The main end point was major adverse cardiac events (MACE: death, myocardial infarction, readmission for unstable angina, or revascularization) at a 4-year median follow-up; secondary end point was 30-day MACE.

Carga de hospitalizaciones recurrentes tras una hospitalización por insuficiencia cardiaca aguda: insuficiencia cardiaca con función sistólica conservada frente a reducida

Introduction and objectives: Heart failure with preserved ejection fraction and reduced ejection fraction share a high mortality risk. However, differences in the rehospitalization burden over time between these 2 entities remains unclear. Methods: We prospectively included 2013 consecutive patients discharged for acute heart failure. Of these, 1082 (53.7%) had heart failure with preserved ejection fraction and 931 (46.2%) had heart failure with reduced ejection fraction. Cox and negative binomial regression methods were used to evaluate the risks of death and repeat hospitalizations, respectively. Results: At a median follow-up of 2.36 years (interquartile range: 0.96-4.65), 1018 patients …

Pronóstico a largo plazo de pacientes con IAMSEST y coronarias sin lesiones obstructivas según los distintos subtipos angiográficos

Resumen Introduccion y objetivos Hay evidencia discordante sobre el pronostico del infarto sin lesiones coronarias obstructivas (MINOCA). Ademas, existen pocos datos del impacto de sus subtipos angiograficos. Los objetivos del estudio son evaluar el impacto pronostico del MINOCA y sus subtipos angiograficos en el seguimiento a largo plazo. Metodos Se incluyo a 591 pacientes consecutivos con IAMSEST a los que se realizo una coronariografia. Los pacientes con MINOCA se clasificaron segun la angiografia en: coronarias lisas, irregularidades leves (estenosis  Resultados En total, 121 pacientes (20,5%) no tenian lesiones obstructivas. El MINOCA se asocio con una menor ocurrencia de MACE (p = 0,0…

Long-Term Prognostic Value of Cognitive Impairment on Top of Frailty in Older Adults after Acute Coronary Syndrome

Frailty is a marker of poor prognosis in older adults after acute coronary syndrome. We investigated whether cognitive impairment provides additional prognostic information. The study population consisted of a prospective cohort of 342 older (&gt
