RESUMO

Patients with sternotomy are advised to follow sternal precautions to avoid the risk of sternal complications. However, there are no standard recommendations, in particular to perform the supine-to-sitting postural change, where sternal asymmetrical force may be applied. The aim of this study was to compare the rotational movement and the use of a tied rope (individual device for supine-to-sitting, "IDSS") to perform the supine-to-sitting postural change. A total of 92 patients (26% female) admitted to a rehabilitative post-surgery ward with sternotomy were assessed for sternal instability. Levels of pain and perceived effort during the two modalities of postural change and at rest were assessed. Patients reported higher values of pain and perceived effort (both p < 0.0005) during rotational movement with respect to the use of the IDSS. Moreover, patients with sternal instability (14%) and female patients with macromastia (25%) reported higher pain than those stable or without macromastia (both p < 0.05). No other risk factors were associated with pain. Thus, the IDSS seems to reduce the levels of pain and perceived effort during the supine-to-sitting postural change. Future studies with quantitative assessments are required to suggest the adoption of this technique, mostly in patients with high levels of pain or with sternal instability.

RESUMO

AIMS: The 6-min walk test (6MWT) and cardiopulmonary exercise test (CPET) are both predictive in heart failure (HFrEF). Although 6MWT substitutes for CPET in HFrEF patients, as submaximal testing may be preferable, its prognostic superiority still needs to be verified, particularly in regard to beta blockers (BBs). We aimed to compare the prognostic role of CPET and 6MWT and investigate whether BB therapy influences the predictive value. METHODS: This is a single-center, retrospective study. Advanced HFrEF patients were followed up for 3 years: events were cardiovascular death or urgent heart transplantation. We analyzed the predictive capacity of CPET and 6MWT in patients, and subdivided according to use of BBs. RESULTS: In a group of 251 HFrEF patients, we found a correlation between meters and peak VO2 (r2 = 0.94). Over the 3-year follow-up, 74 events were recorded. Both CPET and 6MWT variables were correlated with outcome at univariate analysis (meter and VE/VCO2 slope, peak VO2, VO2 at ventilatory anaerobic threshold, percentage predicted of peak VO2), but only percentage predicted of peak VO2 (pppVO2) was an independent predictor. In 103 HFrEF patients on BBs (23 nonsurvivors), neither pppVO2 nor meter were predictive, while in 148 patients not treated with BB (51 with events) pppVO2 was selected as an independent prognostic parameter (P = 0.001). CONCLUSIONS: 6MWT is a valid alternative to CPET, although the percentage of predicted of peak VO2 emerged as the strongest predictor. Nonetheless, our results suggest that both functional derived parameters are not predictive among those patients treated with BBs. Further studies are necessary to confirm these findings.

RESUMO

Heart failure is a complex clinical syndrome with a severe prognosis, despite therapeutic progress. The management of the advanced stages of the syndrome is particularly complex in patients who are referred to palliative care as well as in those who are candidates for cardiac replacement therapy. For the latter group, a prompt recognition of the transition to the advanced stage as well as an early referral to the centers for cardiac replacement therapy are essential elements to ensure that patients follow the most appropriate diagnostic-therapeutic pathway. The aim of this document is to focus on the main diagnostic and therapeutic aspects related to the advanced stages of heart failure and, in particular, on the management of patients who are candidates for cardiac replacement therapy.

RESUMO

As more adults are living into old age, they are predisposed to cardiovascular disease (CVD) and the demand for cardiac rehabilitation is increasing. We aimed to verify predictors of length of stay (LOS) in young (Y) vs older (O) vs very old (VO) CVD patients, admitted to residential cardiac rehabilitation. Patients' demographic and clinical characteristics at admission, as well as Barthel index (BI), Cumulative Illness Rating Scale (CIRS), comorbidity severity/complexity, NYHA classification, left ventricular ejection fraction (LVEF), physical activity level were compared in Y (≤65 years) vs O (between >65 and <76 years) vs VO patients (with an age of ≥76 years) against LOS. In 5,070 consecutively CVD patients were included; they were 1392 Y (38%) 1944 O (35%) 1334 VO patients (27%) and LOS duration was 16±7, 19±9 and 22±10 days, respectively (p<0.0001). In Y, LOS was linked to BI (p=0.000) and to LVEF (p=0.000) at multivariable analysis with area under ROC curve of 0.82, whereas in O, LOS was associated to gender (p=0.013) CIRS severity (p=0.000), BI (p=0.000), LVEF (p=0.000), and in those VO to gender (p=0.004), BI (p=0.000) and medical infusion (p=0.000) at multivariable with ROC curve of 0.83 and 0.74, respectively. In very old patients, a prolonged LOS is related to extra-cardiac conditions. Therefore, we promote a specific cardiac rehabilitation for these patients.

RESUMO

AIMS: The indication for cardiopulmonary exercise testing (CPET) in predictive evaluation has been extended beyond chronic heart failure (HF) patients to include asymptomatic left ventricular dysfunction (ALVD) patients, but its prognostic value is still unclear. We aimed to verify if CPET can predict outcome in ALVD and to identify which of the CPET parameters predictive in chronic HF are also effective in ALVD patients. METHODS AND RESULTS: We screened ALVD (LVEF ≤ 40% without HF symptoms) and HF patients for cardiac death, and compared peak oxygen consumption (pVO2), exertional oscillatory ventilation (EOV), and ventilatory response (VE/VCO2 slope) between survivors and non-survivors. Asymptomatic left ventricular dysfunction and HF patients formed the study population (585 ALVD and 695 HF). Both groups had similar male prevalence (98% vs. 98%; P = 0.345) but ALVD patients were younger (52 ± 10 vs. 60 ± 10 years, P = 0.004). Cardiac death was observed in 142 patients (5% of ALVD, 15% of HF). Exertional oscillatory ventilation occurred in 4% of ALVD, whereas VE/VCO2 slope was significantly lower (30 ± 7 vs. 35 ± 4) and pVO2 higher (16 ± 4 vs. 14 ± 3 mL/kg/min) than in chronic HF patients. Asymptomatic left ventricular dysfunction non-survivors had a significantly greater EOV incidence (13% vs. 3%, P = 0.003), lower pVO2 (13 ± 4 vs. 16 ± 3 mL/kg/min P = 0.000) and higher VE/VCO2 slope (33 ± 7 vs. 31 ± 5, P = 0.032). No ventilatory parameter had prognostic value at multivariable analysis in ALVD patients. CONCLUSIONS: Cardiopulmonary exercise testing can predict events in ALVD patients, but the risk stratification relies on different parameters than in HF patients. Further analysis in a multi-centre trial is required to better quantify the predictive impact of CPET risk parameters in ALVD patients.

RESUMO

BACKGROUND: After the rehabilitation program, patients with left ventricular assist device (LVAD) are discharged home, but the adaption to the daily life with the implant is challenging, both with practical and psychological consequences. Literature is lacking detailed information about the quality of life of LVAD patients and caregivers after discharge to home. OBJECTIVE: This study aimed at evaluating the post-discharge outcomes of both LVAD patients and their caregivers in terms of quality of life, affectivity, and psychological health. METHODS: In this observational follow-up study, LVAD dyads discharged home from 1 year to 6 years were re-contacted by phone and received by mail an envelope with self-report questionnaires. Responses of 39 complete dyads of patients (mean age 68.59 ± 4.31; males: 92.31%) and their caregivers (mean age 61.59 ± 11.64; males: 17.95%) were analyzed. RESULTS: Patients and caregivers reported the moderate levels of anxiety, depression, and caregiver strain, and Illness denial and conscious avoidance were associated between them. The couples often reported that the LVAD has impairments for their sleep and for their affective-sexual relationship. Caregivers often reported impairment in social life and self-care. DISCUSSIONS: Despite the satisfaction for the medical and territorial assistance, patients showed psychological difficulties such as anxious and depressive symptoms and caregivers tend to neglect themselves. Even after a long time from discharge to home, the psychological distress of LVAD patients and caregivers is still considerable. Structured and continuous psychological interventions are required to support their psychological health overtime after the discharge to home.

RESUMO

Cardiac rehabilitation (CR) is a comprehensive program that includes exercise training, titration of medical therapy, lifestyle modification, educational support, and psychosocial assessment. All these components are safe and beneficial resulting in significant improvements in quality of life, functional capacity, mortality, and hospital readmission. Current guidelines support its use in a broad spectrum of cardiac disease. This review focuses on exercise-based CR for heart failure (HF) patients in whom CR is a recommended treatment. Exercise should be prescribed according to a personalized approach, optimizing, and tailoring the rehabilitative program to the patient's characteristics. Specific CR programs are dedicated to older patients, those with HF and preserved ejection fraction, and recipients of cardiac implantable electronic devices or left ventricular assistance device. Telemedicine may increase CR participation and overcome some of the barriers that limit its utilization.

RESUMO

We present a case report of a heart failure patient who underwent cardiopulmonary exercise testing and sleep screening 12 months before and after heart transplantation (HTx). Severe Cheyne-Stokes respiration (CSR) with central sleep apnoea (CSA) was identified either before and after HTx, while periodic breathing during exercise vanished. We suggest that optimization of hemodynamics and medical therapy (low dose of diuretic) did not withdraw the central mechanisms underlying the diathesis for CSR-CSA. While periodic breathing during exercise reversal may support a closer link with an exertional central hemodynamic. This observation indirectly neglects the possible unifying mechanistic background of CSR and periodic breathing, during exercise, in this setting.

RESUMO

BACKGROUND: Despite cardiac rehabilitation for elder people already showed its usefulness, to date it is still not clear the impact of gender and of psychological constructs in influencing the rehabilitation outcomes. AIM: This study aimed at exploring the gender differences of great elders (over 75 years old) in cardiac rehabilitation, with particular attention to the impact of physical and psychological conditions, as depressive symptoms, on long-term post-discharge outcomes. DESIGN: A cohort study design was used and a secondary analysis was conducted. SETTING: Cardiac rehabilitation unit of a postacute rehabilitation Institute. POPULATION: Elderly patients over 75 years old admitted to the cardiac rehabilitation program. METHODS: Psychological and functional variables, such as Barthel Index, BMI, quality of life, and depression measured at admission and discharge from CR were matched with mortality information up to 4 years, used as long-term outcomes. RESULTS: A total of 523 patients, 228 females and 295 males, with a mean age of 76.27 years±3.46 were progressively enrolled. Barthel index at admission and discharge was higher for males than females, 74.10±17.31 vs. 68.90 SD±16.81 (P<0.001), and 95.45±10.64 vs. 92.95±13.03 (p=0.021), respectively, while the relative change from admission to discharge Δ% of Barthel was higher for females 0.25±0.18 than for males 0.21±0.17 (P<0.05). Compared to males, either at admission or discharge females presented more severe depressive symptoms (5.21±3.46 vs. 3.86±2.79, P<0.001; 4.15±3.21 vs. 2.93±2.45, P<0.001) and a worse quality of life (10.58±2.15 vs. 9.55±2.24, P<0.001; 7.5±1.63 vs. 7.02±1.08, P=0.018). Cox proportional analysis revealed that female gender, depression at discharge, Barthel, and Comorbidity Index were associated with higher hazard and shorter survival time. On the other hand, higher BMI was associated with lower hazard and longer survival time. CONCLUSIONS: Elderly women following a CR program present more disability, depression, and a worse QoL than men. Obviously, these characteristics influence the length of hospitalization but with significant improvement. Despite the frail-gender paradox regarding survival, after CR program women have a higher risk of mortality than men. Depression has a significant negative impact on elderly psychophysical health. CLINICAL REHABILITATION IMPACT: Gender-specific and individualized rehabilitation programs should be implemented by considering the discussed physical and psychological risk factors. Further insight about gender differences among over 75 elderlies in CR is provided, this knowledge may be useful for clinicians scheduling recovery plans to promote elderlies' psychological and physical health. Psychological interventions should be implemented to relieve the depressive symptoms among elders.

RESUMO

BACKGROUND: Elderlies in cardiac rehabilitation show a particular frailty due to specific aging issues, thus specific professional psychophysical care is required. AIM: This study aimed at evaluating the effect of a cardiac rehabilitation program enhanced with psychological support on the psychophysical health of elderly subjects aged ≥75. Moreover, the association of psychophysical conditions with the long-term post-discharge course of medical events was examined. DESIGN: This retrospective cohort study was conducted on elderly patients aged ≥75 admitted from 2015 to 2019 to a cardiac rehabilitation program including psychological support. SETTING: The cardiac ward and the psychology unit of a post-acute clinical rehabilitation Institute. POPULATION: A total of 523 elderly inpatients (44% females), aged ≥75 years (mean 79.7±3.46 years), admitted to a cardiac rehabilitation ward due to heart disease. METHODS: Psychological and functional variables such as depression, quality of life, and Barthel Index were measured at hospitalization and at discharge. The medical events after discharge such as emergency department accesses and rehospitalizations were registered. RESULTS: Cardiac rehabilitation showed significant improvements both in elderlies' psychological and physical health. Higher depression levels predicted a worse post-discharge course. Patients who received psychological intervention accessed emergency department and were re-hospitalized significantly later than the others. CONCLUSIONS: Cardiac comprehensive rehabilitation can significantly improve the psycho-physical health of elderly subjects aged ≥75 who benefit of psychological support. Psychological support can enhance the psychophysical health of great elder inpatients in cardiac rehabilitation. CLINICAL REHABILITATION IMPACT: Given the associations with short and long-term outcomes, health professionals should take care of the psychological conditions of elderlies (e.g., depression) by integrating psychological interventions in cardiac rehabilitation in order to promote the elderlies' psychophysical conditions, quality of life, as well as more favorable medical outcomes.

RESUMO

Chronic heart failure (CHF) is a devastating clinical syndrome. Therapeutic schemes have developed rapidly from conventional medical therapy to biomedical strategies, interventional, mechanical, that incorporates left ventricular assistant device (LVAD), surgical, regenerate, and rehabilitating policies. These therapies have improved the symptoms and life expectancy.

RESUMO

Few studies evaluated the effect of cardiac rehabilitation programs on perceived emotional and health status of left ventricular assist device (LVAD) patients, and none explored their effect on caregivers' strain. We enrolled 119 adult LVAD patients, together with their caregivers (n = 91), in two Rehabilitation Institutes that provided inpatient multidisciplinary activities. At admittance and prior to discharge they completed questionnaires evaluating patient emotional state and subjective perception of health status, caregiver strain, and patient and caregiver perception of the VAD. Six months after discharge, patients and caregivers were contacted again and asked specific questions about their quality of life. Patients' state anxiety and depression symptoms significantly diminished at discharge (0.000), whereas their perception of general health status rose (0.000). Caregivers' perceived strain also significantly decreased (0.001) and the perceived device management skill grew both for patients and caregivers (0.000). A substantial amount (36%) of psychologically frail patients and caregivers, although improving their emotional condition, never reached that of the less frail subjects. At the 6-month follow-up, both patients and caregivers appeared stable in evaluating respectively their general health and their caregiving-related strain, compared to discharge. Our data show that a comprehensive inpatient rehabilitation program improves the emotional state of LVAD patients and of their caregivers, even in psychologically frailer subjects. Team approach makes patients and caregivers self-confident about device management, increasing their knowledge, clarifying their doubts, and encouraging them to handle the difficulties met during the rehabilitation period, suggesting strategies to cope with daily life at home.

RESUMO

Exercise training (ET) and secondary prevention measures in cardiovascular disease aim to stimulate early physical activity and to facilitate recovery and improve health behaviours. ET has also been proposed for heart failure patients with a ventricular assist device (VAD), to help recovery in the patient's functional capacity. However, the existing evidence in support of ET in these patients remains limited. After a review of current knowledge on the causes of the persistence of limitation in exercise capacity in VAD recipients, and concerning the benefit of ET in VAD patients, the Heart Failure Association of the European Society of Cardiology has developed the present document to provide practical advice on implementing ET. This includes appropriate screening to avoid complications and then starting with early mobilisation, ET prescription is individualised to meet the patient's needs. Finally, gaps in our knowledge are discussed.

RESUMO

BACKGROUND: Exercise oscillatory ventilation is an ominous outcome sign in heart failure due to reduced left ventricular ejection fraction; currently, the prevalence of exercise oscillatory ventilation is unknown in left ventricular assist device recipients. METHODS: We studied cardiopulmonary exercise testing in heart failure due to reduced left ventricular ejection fraction or left ventricular assist device patients and exercise oscillatory ventilation was defined according to Kremser's criteria. RESULTS: The occurrence of exercise oscillatory ventilation was similar in either heart failure due to reduced left ventricular ejection fraction (192 patients, 8%) or left ventricular assist device patients (85 recipients, 10%), even though the mean peak oxygen consumption and elevated ventilatory response to exercise slope was lower and higher in left ventricular assist device recipients, respectively, but the occurrence of exercise oscillatory ventilation was comparable among heart failure patients due to reduced left ventricular ejection fraction and left ventricular assist device, if those with impaired exercise capacity were considered. Of note, left ventricular assist device recipients with exercise oscillatory ventilation had a higher end-diastolic left ventricular volume and systolic pulmonary artery pressure at rest. CONCLUSIONS: Using the largest cohort of left ventricular assist device patients performing cardiopulmonary exercise testing, we demonstrated that the occurrence of exercise oscillatory ventilation is similar in heart failure due to reduced left ventricular ejection fraction and left ventricular assist device patients. Recipients with exercise oscillatory ventilation might have haemodynamic and ventilatory dysfunction during exercise, but other factors could play a role, i.e. the duration and severity of heart failure before left ventricular assist device implantation together with the coexistence of morbidity.

RESUMO

Exercise ventilation/perfusion matching in continuous-flow left ventricular assist device recipients (LVAD) has not been studied systematically. Twenty-five LVAD and two groups of 15 reduced ejection fraction chronic heart failure (HFrEF) patients with peak VO2 matched to that of LVAD (HFrEF-matched) and ≥14 ml/kg/min (HFrEF≥14), respectively, underwent cardiopulmonary exercise testing with arterial blood gas analysis, echocardiogram and venous blood sampling for renal function evaluation. Arterial-end-tidal PCO2 difference (P(a-ET)CO2) and physiological dead space-tidal volume ratio (VD/VT) were used as descriptors of alveolar and total wasted ventilation, respectively. Tricuspid annular plane systolic excursion/pulmonary artery systolic pressure ratio (TAPSE/PASP) and blood urea nitrogen/creatinine ratio were calculated in all patients and used as surrogates of right ventriculo-arterial coupling and circulating effective volume, respectively. LVAD and HFrEF-matched showed no rest-to-peak change of P(a-ET)CO2 (4.5±2.4 vs. 4.3±2.2 mm Hg and 4.1±1.4 vs. 3.8±2.5 mm Hg, respectively, both p >0.40), whereas a decrease was observed in HFrEF≥14 (6.5±3.6 vs. 2.8±2.0 mm Hg, p <0.0001). Rest-to-peak changes of P(a-ET)CO2 correlated to those of VD/VT (r = 0.70, p <0.0001). Multiple regression indicated TAPSE/PASP and blood urea nitrogen/creatinine ratio as independent predictors of peak P(a-ET)CO2. LVAD exercise gas exchange is characterized by alveolar wasted ventilation, i.e. hypoperfusion of ventilated alveoli, similar to that of advanced HFrEF patients and related to surrogates of right ventriculo-arterial coupling and circulating effective volume.

RESUMO

BACKGROUND: The hemodynamic definitions of pulmonary hypertension (PH) in left heart disease have recently been refined to better match the characteristics required to reflect the presence of pulmonary vascular disease. Accordingly, we tested the hypothesis that abnormalities in the stiffness of pulmonary circulation would persist after heart transplantation in patients with combined post-capillary and pre-capillary PH (Cpc-PH) in contrast to those with isolated post-capillary PH (Ipc-PH). METHODS: We retrospectively analyzed right heart hemodynamics in a cohort of 295 consecutive patients with heart failure and advanced left ventricular systolic dysfunction (LVSD) before and 1 year after heart transplantation. RESULTS: According to their baseline hemodynamic profile, patients were classified as: 75 Cpc-PH, 111 Ipc-PH, and 98 without PH (no-PH), and 11 pre-capillary PH. One year after heart transplantation, pulmonary artery pressures, pulmonary vascular resistance and cardiac index normalized in all patients regardless of the baseline hemodynamic profile. However, pulmonary arterial compliance remained lower in Cpc-PH patients (from 1.6±1.2 at baseline to 3.7±1.4 ml/mmHg at 1 year) than in Ipc-PH (from 1.2±2.0 to 4.4±2.3 ml/mmHg) and no-PH patients (from 3.7±2.0 to 4.5±1.8 ml/mmHg); (adjusted p = 0.03 Ipc-PH vs. Cpc-PH INT<0.001). CONCLUSIONS: In heart failure patients with advanced LVSD, a hemodynamic profile characterized by Cpc-PH predicts the persistence of a stiffer pulmonary circulation at 1 year after heart transplantation.
