Predictors of physical frailty improvement in older patients enrolled in a multidisciplinary cardiac rehabilitation program.

Cardiac rehabilitation (CR) improves clinical and functional recovery in older patients after acute cardiac syndromes, whose outcome is influenced by cardiac disease severity, but also by comorbidity and frailty. The aim of the study was to analyze the predictors of physical frailty improvement during the CR program. Data were collected in all patients aged > 75 years consecutively admitted from 1 January to December 2017 to our CR, consisting of 5-day-per-week of 30-min session of biking or calisthenics on alternate days for 4 weeks. Physical frailty was measured with short physical performance battery (SPPB) at the entry and the end of CR. Outcome was represented by an increase of at least 1 point in the SPPB score from baseline to the end of the CR program. In our study population of 100 patients, mean age 81 years, we demonstrated that a strong predictor of improvement in SPPB score was the poorer performance in the test at baseline; for Δ-1 point of score, we registered an OR 2.50 (95% CI = 1.64-3.85; p = 0.001) of probability to improve the physical performance at the end of CR. Interestingly those patients with worse performance at SPPB balance and chair standing task showed greater probability of ameliorating their physical frailty profile at the end of CR. Our data strongly suggest that CR program after acute cardiac syndrome produces a significant physical frailty improvement in those patients with worse frailty phenotype with an impairment in chair standing or balance at entry.

New Drugs for Heart Failure: What is the Evidence in Older Patients?

Heart failure (HF) is a major public health concern, with a high prevalence in the older population. The majority of randomized clinical trials evaluating new emerging pharmacologic agents for HF (eg, angiotensin receptor-neprilysin inhibitors, sodium-glucose cotransporter 2 inhibitors, intravenous iron for deficiency treatment, transthyretin stabilizers, soluble guanylate cyclase stimulators, cardiac myosin activators, and new potassium binders) have found positive results on various clinical outcomes, particularly in patients with reduced ejection fraction. These treatments might have an important role in the management of older patients as well. Nevertheless, trials demonstrating benefit of these drugs have involved patients significantly younger (on average, approximately 10 years) and fewer comorbidities than those commonly encountered in clinical practice. We describe the recent evidence regarding the newest HF drugs and their applicability to older individuals in terms of efficacy and safety, and we discuss their effects on outcomes particularly valuable to older patients, such as preservation of cognitive function, functional status, independence, and quality of life. Although available subgroup analyses seem to confirm efficacy and safety across the age spectrum for some of these drugs, their effects on older patients centered outcomes often have been neglected. Future HF trials should be designed to include older patients more representative of the real clinical practice, to overcome generalizability biases.

Cardiac Rehabilitation in Advanced aGE after PCI for acute coronary syndromes: predictors of exercise capacity improvement in the CR-AGE ACS study.

BACKGROUND: The positive effect of cardiac rehabilitation (CR) on outcomes after acute coronary syndromes (ACS) is established. Nevertheless, enrollment rates into CR programs remain low, although ACS carry a high risk of functional decline particularly in the elderly. AIM: We aimed to determine if a multidisciplinary CR improves exercise capacity in an older population discharged after ACS systematically treated with PCI. METHODS: CR-AGE ACS is a prospective, single-center, cohort study. All patients aged 75+ years consecutively referred to Cardiac Rehabilitation outpatient Unit at Careggi University Hospital, were screened for eligibility. Moderate/severe cognitive impairment, disability in 2+ basic activities of daily living, musculoskeletal diseases, contraindication to Cardiopulmonary Exercise Test, and diseases with an expected survival < 6 months, were exclusion criteria. Participants attended a CR program, based on 5-day-per-week aerobic training sessions for 4 weeks. RESULTS: We enrolled 253 post-ACS patients with a mean age 80.6 ± 4.4 years. After CR, 136 (56.2%) 77 (31.3%) patients obtained, respectively, at least a moderate (∆+5%) or an optimal (∆+15%) increase in VO2peak. Baseline VO2peak (- 1 ml/kg/min: OR 1.18; 95% CI 1.09-1.28), the number of training sessions (+1 session: OR 1.07; 95% CI 1.01-1.15), and mild-to-moderate baseline disability (yes vs. no: OR 0.22; 95% CI 0.01-0.57) were the predictors of VO2peak changes. CONCLUSIONS: A CR program started early after discharge from ACS produces a significant increase in exercise capacity in very old patients with mild-to-moderate post-acute physical impairment. Baseline VO2peak, the number of training sessions, and the level of baseline disability are the independent predictors of improvement.

Role of Frailty on Risk Stratification in Cardiac Surgery and Procedures.

The number of older people candidates for interventional cardiology, such as PCI but especially for transcatheter aortic valve implantation (TAVI) , would increase in the future. Generically, the surgical risk, the amount of complications in the perioperative period, mortality and severe disability remain significantly higher in the elderly than in younger. For this reason it's important to determine the indication for surgical intervention, using tools able to predict not only the classics outcome (length of stay, mortality), but also those more specifically geriatrics, correlate to frailty: delirium, cognitive deterioration, risk of institutionalization and decline in functional status. The majority of the most used surgical risks scores are often specialist-oriented and many variables are not considered. The need of a multidimensional diagnostic process, focused on detect frailty, in order to program a coordinated and integrated plan for treatment and long term follow up, led to the development of a specific geriatric tool: the Comprehensive Geriatric Assessment (CGA). The CGA has the aim to improve the prognostic ability of the current risk scores to capture short long term mortality and disability, and helping to resolve a crucial issue providing solid clinical indications to help physician in the definition of on interventional approach as futile. This tool will likely optimize the selection of TAVI older candidates could have the maximal benefit from the procedure.

ANMCO/SIC/SICI-GISE/SICCH Executive Summary of Consensus Document on Risk Stratification in elderly patients with aortic stenosis before surgery or transcatheter aortic valve replacement.

Aortic stenosis is one of the most frequent valvular diseases in developed countries, and its impact on public health resources and assistance is increasing. A substantial proportion of elderly people with severe aortic stenosis is not eligible to surgery because of the advanced age, frailty, and multiple co-morbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy. However, a significant percentage of patients die or show no improvement in quality of life (QOL) in the follow-up. In the decision-making process, it is important to determine: (i) whether and how much frailty of the patient influences the risk of procedures; (ii) how the QOL and the individual patient's survival are influenced by aortic valve disease or from other associated conditions; and (iii) whether a geriatric specialist intervention to evaluate and correct frailty or other diseases with their potential or already manifest disabilities can improve the outcome of surgery or TAVI. Consequently, in addition to risk stratification with conventional tools, a number of factors including multi-morbidity, disability, frailty, and cognitive function should be considered, in order to assess the expected benefit of both surgery and TAVI. The pre-operative optimization through a multidisciplinary approach with a Heart Team can counteract the multiple damage (cardiac, neurological, muscular, respiratory, and kidney) that can potentially aggravate the reduced physiological reserves characteristic of frailty. The systematic application in clinical practice of multidimensional assessment instruments of frailty and cognitive function in the screening and the adoption of specific care pathways should facilitate this task.

Cardiac surgery in the elderly: What goals of care?

At present, the majority of cardiac surgery interventions have been performed in the elderly with successful short-term mortality and morbidity, however significant difficulties must to be underlined about our capacity to predict long-term outcomes such as disability, worsening quality of life and loss of functional capacity.The reason probably resides on inability to capture preoperative frailty phenotype with current cardiac surgery risk scores and consequently we are unable to outline the postoperative trajectory of an important patients' centered outcome such as disability free survival. In this perspective, more than one geriatric statements have stressed the systematic underuse of patient reported outcomes in cardiovascular trials even after taking account of their relevance to older feel and wishes. Thus, in the next future is mandatory for geriatric cardiology community closes this gap of evidences through planning of trials in which patients' centered outcomes are considered as primary goals of therapies as well as cardiovascular ones.

Age, left atrial dimension and arterial stiffness after external cardioversion of atrial fibrillation. A vascular component in arrhythmia maintenance? Results from a preliminary study.

BACKGROUND AND AIMS: Atrial fibrillation (AF) is the most frequent arrhythmia in elderly patients. Aims of this study were to evaluate the predictors of arterial stiffness after external cardioversion (ECV) of AF and to establish whether a link exists between vascular properties and left atrial diameter (LAD). METHODS: We studied 33 patients (age 73 ± 12 years). After 5 h from ECV of persistent AF, an echocardiogram was recorded and arterial stiffness was evaluated with cardio-ankle vascular stiffness index (CAVI). RESULTS: In multivariate analysis (R = 0.538, p = 0.006), CAVI (mean 9.60 ± 1.63) increased with age (p = 0.018) and with an AF length ≤3 months (p = 0.022). LAD was significantly related to CAVI (p = 0.007) even after adjustment for interventricular septum thickness (p = 0.018) (R = 0.574, p = 0.002). CONCLUSIONS: In patients with AF, immediately after ECV, arterial stiffness is associated with age and AF length, and could represent an important factor for left atrium remodeling and, therefore, for AF maintenance.

Neurocognitive profile of patients with continuous flow left ventricular assist device.

The increase of severe heart failure and the consequent reduction of the organ availability for transplantation has led to, in recent years, the introduction of the LVAD as replacement therapy to heart transplantation. Severe Heart Failure patients show cognitive deficits in various domains especially in executive functions, memory and speed of proceedings, due to different neurophysiopathological processes including chronic hypoperfusion and subsequent damage to hippocampal and para-hippocampal cortical areas. It is also known that these deficits improve after heart transplantation. We carried out a literature review selecting studies that analyzed the cognitive changes in patients with severe heart failure after implantation of the Continuous Flow Left Ventricular Assist Device. According to the inclusion criteria, we selected four studies since 2005 that presented a comprehensive neurocognitive assessment. The results show that the cognitive profile, with the implantation of LVAD improves in memory and executive domains, and this improvements results stable in short-medium time. The effects would also be independent of the type of flow produced by the device (pulsatile vs continuous). We believe that further studies are required to explore the relationship between LVAD and cognitive function in severe heart failure.

Gender difference in long-term effect of cardiac rehabilitation; data from CRAGE-extra study.

Introduction: The positive effect of cardiac rehabilitation (CR) is demonstrated in younger and older patients. However, it is quite debated whether the beneficial effect is similarly maintained in both genders during follow-up. Aim: to determine if the improvement obtained after CR remained significant at 1-year follow-up in older population, testing the influence of gender on this outcome. Methods: All patients aged 75+ years consecutively referred to Cardiac Rehabilitation outpatient Unit at Careggi University Hospital were screened for eligibility. All patients attended a CR program, based on 5-day-per-week aerobic training sessions for 4 weeks and they were evaluated at the end of CR at 6 and 12 months of follow-up. Results: 361 patients with a mean age 80.6 ± 4.4 years with a complete 1-year follow-up were enrolled in the study, 87.5 % of them had an acute coronary event, and 27.6 % were females. The increase in exercise capacity at the end of CR and at 1-year follow-up was statistically significant (VO2 peak: +8.7 % in males p < 0.001, +8.5 % in females p < 0.001; distance walked at 6-min test: +7.3 % in males p < 0.001, +10.2 % in females p < 0.001, respectively); the trajectory of exercise improvement at 6 and 12 months of FU was similar in men and women without significant decrease (VO2 peak-ml/kg/min: CR discharge vs 1 year FU = 15.2 vs 15,0 p: NS; distance walked-meters: CR discharge vs 1 year FU = 445.5 vs 440.6, p: NS) from end of CR to 1-year. Conclusions: the improvement in exercise tolerance obtained with CR program is still maintained at 1-year FU without significant influence of gender in our very old population.

Serial Changes in Cardiopulmonary Exercise Testing Parameters in Untreated Patients With Transthyretin Cardiac Amyloidosis.

BACKGROUND: Transthyretin amyloid cardiomyopathy (ATTR-CM) is associated with a progressive reduction of functional capacity. The progression of cardiopulmonary exercise testing (CPET) parameters over time is still unknown. METHODS: In this study, 55 patients with ATTR-CM underwent 2 serial cardiologic evaluations and CPETs in a national referral center for cardiac amyloidosis (Careggi University Hospital, Florence). RESULTS: Forty-three patients (78%) had wild-type ATTR. Median age was 80 years (interquartile range [IQR] 76-83 years), and 50 of the patients (91%) were men. At baseline, median peak oxygen consumption (pVO2) was 15 mL/kg/min (IQR 12-18 mL/kg/min), percentage of predicted pVO2 (%ppVO2) was 71% (IQR 60%-83%) and VE/VCO2 slope was 31 (IQR 26-34). After a median follow-up of 14 months (IQR 13-16 months), pVO2, %ppVO2 and VE/VCO2 slope were significantly worsened (-1.29 mL/kg/min [95% confidence interval (CI): -1.85 to -0.74; P < 0.01], -4.5% [95% CI: -6.9 to -2.02; P < 0.01], and 8.6 [95% CI 6-11; P < 0.01], respectively). Furthermore, exercise time (-39 s, 95% CI: -59 to -19; P < 0.01), exercise tolerance (-0.47 metabolic equivalents, 95% CI: -0.69 to -0.2; P < 0.01), and peak systolic pressure (-10.8 mm Hg, 95% CI: -16.2 to -5.4; P < 0.01) were significantly reduced. The worsening in CPET variables did not correspond with a significant change in echocardiographic parameters. CONCLUSIONS: Cardiorespiratory response to exercise significantly worsened over a short period of time in patients with ATTR-CM. Serial CPET may be useful to identify early disease progression.

Epicardial adipose tissue and insulin resistance in patients with coronary artery disease with or without left ventricular dysfunction.

BACKGROUND: Epicardial adipose tissue (EAT) is a visceral fat that fulfills two important functions: lipid-storage and secretion of adipokines with pro-inflammatory and pro-atherogenic properties. It has been suggested that EAT may affect the pathogenesis of atherosclerosis and the clinical course of coronary artery disease (CAD). In patients with obesity, diabetes and metabolic syndrome, the epicardial adipose tissue is enlarged. Little is known about the role of EAT in left ventricular dysfunction. Aim of this study was to evaluate the ability of insulin resistance to predict EAT thickness in patients with significant CAD and systolic dysfunction. METHODS: We enrolled 114 subjects diagnosed with CAD by angiography. The majority underwent revascularization after an acute coronary syndrome. Patients were considered affected by significant left ventricular dysfunction when EF was < or = 40%. Three indexes of insulin resistance, the HOMA IR index, the insulin sensitivity QUICKI index, and the novel adiponectin/resistin index (ADIPO-IRAR) were calculated and correlated to EAT thickness. Epicardial fat was measured by echocardiography according to standardized methods. RESULTS: Subjects with diabetes and with a history of hypercholesterolemia had thicker EAT compared to controls. Potassium levels and all three indexes of insulin resistance were the best independent predictors of EAT in the study population as a whole and in the subset of patients with left ventricular dysfunction. In the latter group the novel ADIPO-IRAR index displayed the strongest predictivity. CONCLUSION: Insulin resistance is an independent predictor of EAT thickness in patients affected by CAD, also in the presence of significant left ventricular dysfunction.

Prediction of worsening postoperative renal function in older candidates to elective cardiac surgery: Choosing the best eGFR formula may not be enough.

BACKGROUND: Though renal impairment is highly prevalent in older patients and influence post-operative outcomes in cardiac surgery; its prognostic relevance is debated and not fully assessed by surgical risk scores. OBJECTIVE: We investigated the predictive role of estimated glomerular filtration rate formulas for in-hospital worsening renal function (WRF) after cardiac surgery. METHODS: We prospectively enrolled in single-center cohort study, patients aged ≥ 75 years candidate to elective cardiac surgery. Four creatinine-based equations were used to calculate estimated glomerular filtration rate (eGFR) formulas: Cockroft-Gault, Modification of Diet in Renal Disease, Chronic Kidney Disease Epidemiology, and Berlin Initiative Study 1 formulas. Each patient underwent geriatric and clinical evaluation before surgery with calculation of the Society of Thoracic Surgeons scores. In-hospital WRF was defined as a composite of an increase in SCr ≥0.5 mg/dl or the occurrence of grade III KDIGO acute kidney injury. The association between each eGFR equation, alone and in models including clinical variables, and WRF was analyzed using logistic regressions and ROC analysis. RESULTS: WRF occurred in 69 patients (19.8%), and the predictors of WRF were previous acute myocardial infarction, hypertension, 4-mt gait speed performance, and preoperative eGFR, irrespective of the equation used. With all equations, inclusion of these additional variables in the logistic regression models improved the prediction of WRF (AUCs 0.798-0.810). CONCLUSIONS: An accurate assessment of renal function and of physical performance should be incorporated into cardiac surgery risk scores to improve prediction of in-hospital WRF and, hence, risk stratification in older adults undergoing elective cardiac surgery.

Prognostic value of cardiopulmonary exercise testing in patients with transthyretin cardiac amyloidosis.

The aim of this study is to evaluate the prognostic value of cardiopulmonary testing (CPET) in a cohort of patients with transthyretin cardiac amyloidosis (ATTR-CA). ATTR-CA is associated with a progressive reduction in functional capacity. The prognostic role of CPET parameters and in particular of normalized peak VO2 (%ppVO2) remains to be thoroughly evaluated. In this study, 75 patients with ATTR-CA underwent cardiological evaluation and CPET in a National Referral Center for cardiac amyloidosis (Careggi University Hospital, Florence). Fifty-seven patients (76%) had wild-type ATTR. Median age was 80 (75-83) years, 68 patients (91%) were men. Peak oxygen consumption (14.1 ± 4.1 ml/kg/min) and %ppVO2 (68.4 ± 18.8%) were blunted. Twenty-seven (36%) patients had an abnormal pressure response to exercise. After a median follow-up of 25 (12-31) months, the composite outcome of death or heart failure hospitalization was registered in 19 (25.3%) patients. At univariate analysis %ppVO2 was a stronger predictor for the composite outcome than peak VO2. %ppVO2 and NT-proBNP remained associated with the composite outcome at multivariate analysis. The optimal predictive threshold for %ppVO2 was 62% (sensitivity: 71%; specificity: 68%; AUC: 0.77, CI 0.65-0.88). Patients with %ppVO2 ≤ 62%and NT-proBNP > 3000 pg had a worse prognosis with 1- and 2-year survival of 69 ± 9% and 50 ± 10%, respectively. CPET is a safe and useful prognostic tool in patients with ATTR-CA. CPET may help to identify patients with advanced disease that may benefit from targeted therapy.

Adiponectin, diabetes and ischemic heart failure: a challenging relationship.

BACKGROUND: Several peptides, named adipokines, are produced by the adipose tissue. Among those, adiponectin (AD) is the most abundant. AD promotes peripheral insulin sensitivity, inhibits liver gluconeogenesis and displays anti-atherogenic and anti-inflammatory properties. Lower levels of AD are related to a higher risk of myocardial infarction and a worse prognosis in patients with coronary artery disease. However, despite a favorable clinical profile, AD increases in relation to worsening heart failure (HF); in this context, higher adiponectinemia is reliably related to poor prognosis. There is still little knowledge about how certain metabolic conditions, such as diabetes mellitus, modulate the relationship between AD and HF.We evaluated the level of adiponectin in patients with ischemic HF, with and without type 2 diabetes, to elucidate whether the metabolic syndrome was able to influence the relationship between AD and HF. RESULTS: We demonstrated that AD rises in patients with advanced HF, but to a lesser extent in diabetics than in non-diabetics. Diabetic patients with reduced systolic performance orchestrated a slower rise of AD which began only in face of overt HF. The different behavior of AD in the presence of diabetes was not entirely explained by differences in body mass index. In addition, NT-proBNP, the second strongest predictor of AD, did not differ significantly between diabetic and non-diabetic patients. These data indicate that some other mechanisms are involved in the regulation of AD in patients with type 2 diabetes and coronary artery disease. CONCLUSIONS: AD rises across chronic heart failure stages but this phenomenon is less evident in type 2 diabetic patients. In the presence of diabetes, the progressive increase of AD in relation to the severity of LV dysfunction is hampered and becomes evident only in overt HF.

[The complexity of risk stratification in older patient candidate to non-cardiac surgery]. / La complessità della stratificazione del rischio nel paziente anziano cardiopatico candidato a chirurgia non cardiaca.

During the last decades the older patients who are candidates for surgery have grown exponentially due to the increase in life expectancy and the surgery technique improvement. Despite this, the mortality remains high and our ability to predict the surgery outcomes continues to be low in the elderly. The main reason is related to different difficulties; we are unable to differentiate properly the chronological from the biological age, and the current surgery and cardiology risk scores are poorly geriatric-oriented. We must underline how the measure of comorbidity during the preoperative evaluation is often limited to a simple count of comorbid conditions, without a more detailed assessment of their severity. On the other hand different comorbidity scores have been validated in geriatric populations showing a good correlation with prognosis, such as the Index of Coexisting Disease-ICED or the Geriatric Index of Comorbidity-GIC. Our predictive deficiency about the outcomes is linked to poor attention for identifying the frail patients that are already at high risk of disability. Recently, the evaluation of frailty is a key target for geriatric medicine, and geriatricians have developed various methods for measuring this parameter and suggesting the physical performance indexes as a reliable surrogate of frailty. Surrogate frailty measures, such as the "gait speed" or the "Short Physical Performance Battery-SPPB" seem to be the valid tools for evaluating older surgery patients due to their simplicity and short administration time. We think that the future challenge will be their widespread use in this specific clinical setting.

COVID-19, Vulnerability, and Long-Term Mortality in Hospitalized and Nonhospitalized Older Persons.

OBJECTIVE: Studies suggesting that vulnerability increased short-term mortality in older patients with COVID-19 enrolled hospitalized patients and lacked COVID-negative comparators. Aim of this study was to examine the relationship between frailty and 1-year mortality in older patients with and without COVID-19, hospitalized and nonhospitalized. DESIGN: Cohort study. SETTING AND PARTICIPANTS: Patients over 75 years old accessing the emergency departments (ED) were identified from the ED archives in Florence, Italy. METHODS: Vulnerability status was estimated with the Dynamic Silver Code (DSC). COVID-19 hospital discharges (HC+) were compared with non-COVID-19 discharges (HC-). Linkage with a national COVID-19 registry identified nonhospitalized ED visitors with (NHC+) or without COVID-19 (NHC-). RESULTS: In 1 year, 48.4% and 33.9% of 1745 HC+ and 15,846 HC- participants died (P < .001). Mortality increased from 27.5% to 64.0% in HC+ and from 19.9% to 51.1% in HC- across DSC classes I to IV, with HC+ vs HC- hazard ratios between 1.6 and 2.2. Out of 1039 NHC+ and 18,722 NHC- participants, 18% and 8.7% died (P < .001). Mortality increased from 14.2% to 46.7% in NHC+ and from 2.9% to 26% in NHC- across DSC; NHC+ vs NHC- hazard ratios decreased from 5.3 in class I to 2.0 in class IV. CONCLUSIONS AND IMPLICATIONS: In hospitalized older patients, mortality increases with vulnerability similarly in the presence and in the absence of COVID-19. In nonhospitalized patients, vulnerability-associated excess mortality is milder in individuals with than in those without COVID-19. The disease reduces survival even when background risk is low. Thus, apparently uncomplicated patients deserve closer clinical monitoring than commonly applied.

Role of new drug therapies and innovative procedures in older patients with heart failure: from trials to clinical practice.

During earliest years, new drug-therapies and novel interventional therapies have been tested to modify the detrimental effect of secondary valve diseases, adverse ventricular remodelling and persistent fluid overload in HF patients. However, the increased prevalence of older or very old patients with HF has made their widespread implementation more problematic due to complex comorbidity, frailty, or overt disability. This growing older population, often excluded by randomized trials, but with elevated risk of hospitalization, required a different clinical and management approach that allows clinicians to take full advantage in reducing mortality and morbidity from these new pharmacological and instrumental therapies. In this perspective, the role of multidisciplinary Heart Team is mandatory for better define a correct decision-making process and tailoring the best pharmacological therapy in each patient and to program a continuum care in a post-acute phase of treatment. In addition, the possibility to plan multicentre registries of several complex cases evaluated by Heart Team could become a very important source of real world data to further refine indications and contraindications of different highly technological therapeutic approach, today based often on randomized clinical trials that do not represent faithfully the current clinical practice population.

Telehealth Management and Risk Stratification of Older Patients With Chronic Heart Failure During COVID-19 Pandemic: Prognostic Evaluation of the TeleHFCovid19-Score.

OBJECTIVES: To evaluate 6-month risk stratification capacity of the newly developed TeleHFCovid19-Score for remote management of older patients with heart failure (HF) during the coronavirus disease 2019 pandemic. DESIGN: Monocentric observational prospective study. SETTING AND PARTICIPANTS: Older HF outpatients remotely managed during the first pandemic wave. METHODS: The TeleHFCovid19-Score (0-29) was obtained by an ad hoc developed multiparametric standardized questionnaire administered during telephone visits to older HF patients (and/or caregivers) followed at our HF clinic. Questions were weighed on the basis of clinical judgment and review of current HF literature. According to the score, patients were divided in progressively increasing risk groups: green (0-3), yellow (4-8), and red (≥9). RESULTS: A total of 146 patients composed our study population: at baseline, 112, 21, and 13 were classified as green, yellow, and red, respectively. Mean age was 81±9 years, and women were 40%. Compared to patients of red and yellow groups, those in the green group had a lower use of high-dose loop diuretics (P < .001) or thiazide-like diuretics (P = .027) and had reported less frequently dyspnea at rest or for basic activities, new or worsening extremity edema, or weight increase (all P < .001). At 6 months, compared with red (62.2%) and yellow patients (33.3%), green patients (8.9%) presented a significantly lower rate of the composite outcome of cardiovascular death and/or HF hospitalization (P < .001). Moreover, receiver operating characteristic curve analysis showed a high sensibility and specificity of our score at 6 months (area under the curve = 0.789, 95% CI 0.682-0.896, P < .001) with a score <4.5 (very close to green group cutoff) that identified lower-risk subjects. CONCLUSIONS AND IMPLICATIONS: The TeleHFCovid19-Score was able to correctly identify patients with midterm favorable outcome. Therefore, our questionnaire might be used to identify low-risk chronic HF patients who could be temporarily managed remotely, allowing to devote more efforts to the care of higher-risk patients who need closer and on-site clinical evaluations.

Predictors of 1-year outcome in very old patients managed in a Heart Failure Unit after an acute decompensation.

PURPOSE: Consensus exits about the clinical benefits of an early referral to multidisciplinary Heart Failure Unit-HFU for old frail patients with HF. Nevertheless, few data are present regarding the prognosis and the predictors of outcome in oldest-old patients managed in this clinical setting. The aim of present study is to identify predictors of 1-year all-cause mortality in very old patients enrolled in our multidisciplinary HFU after an episode of acute decompensated HF. METHODS: This study is a retro-prospective, single-center cohort analysis of patients managed in our multidisciplinary HFU. Inclusion criterion was diagnosis of HF according to ESC guidelines and age ≥ 85 years, while no exclusion criteria were pre-defined. Baseline clinical and comprehensive geriatric evaluations were recorded during the first visit and follow-up visits were repeated according to our standardized timetable protocol. Primary end-point was 1-year all-cause mortality. RESULTS: We enrolled 75 patients aged 89.2 ± 2.8 years; 39 (52.0%) were females. During 1-year follow-up, seventeen patients (22.7%) died. Residual congestion with higher level (> 4) of EVEREST score (HR 1.24: 95% CI 1.04-1.47) and living alone (HR 3.34: 95% CI 1.16-9.64) resulted the two independent predictors of 1-year all-cause mortality at the multivariate Cox regression model. Finally, patients living alone and with an EVEREST score > 4 experienced a worse prognosis as clearly described by a steeper descendent Kaplan-Meier curve. CONCLUSION: In a very old population of patients after an acute decompensated HF, residual congestion and social isolation as living alone identify those with high risk of 1-year death.

Lower extremity performance predicts length of hospital stay in older candidates to elective cardiac surgery.

INTRODUCTION: Prolonged hospital stay must be considered as risk factor for poor outcomes after cardiac surgery; different variables have been advocated as predictors of in-hospital stay. Nevertheless, most patients requiring prolonged hospital stay are frail older subjects; thus, we hypothesized a significant influence of pre-operative physical performance, as a frailty measure, on in-hospital stay after elective cardiac surgery. METHODS: In a prospective, single-center, cohort study we enrolled patients aged 75+ years referred to our Division of Cardiac Surgery at Careggi University Hospital, for their first elective cardiac surgery. All participants were preoperatively evaluated by a team composed by a cardiac surgeon, a cardiologist, an anaesthesist, and a geriatrician to assess global cardiac surgery risk; lower extremity performance was measured with the Short Physical Performance Battery-SPPB. RESULTS: A total of 518 patients were included in the study. Mean age was 79.5 ±â€¯3.3 years; 256 (49.4%) were women. Isolated coronary by pass graft was performed in 37 patients (7.1%), isolated valve surgery in 115 (22.0%), and combined cardiac surgery procedures in 366 (70,9%). In a multivariable model, SPPB score was strongly associated with hospital length of stay both as continuous, categorized and dichotomous variable (p < 0.001; p = 0.002; p = 0.002 respectively) in all study population, and in subgroup of patients candidate to cardiac surgery considered by the Society of Thoracic Surgeons calculator score (p = 0.023; p = 0.056; p = 0.013 respectively). CONCLUSIONS: Our findings support the use of pre-operative SPPB evaluation before elective cardiac surgery based on the independent ability to predict length of hospital stay.
