Short- and long-term effects of a cardiac rehabilitation program in patients implanted with a left ventricular assist device.

The efficacy of cardiac rehabilitation in heart-failure patients who received a left-ventricular assist device (LVAD) instead of heart transplantation (HTx) is still unclear. This study aims to evaluate whether cardiac rehabilitation is beneficial in LVAD as HTx patients in the short term and whether its effects in LVAD patients persist over time. Twenty-five LVAD patients were evaluated by functional and psychological tests at admission (T0) and discharge (T1) of a 4-week inpatient structured rehabilitation program, and follow-ups 3 (T2), 6 (T3), and 12 months (T4) after discharge. Twenty-five matched HTx patients were also studied from T0 to T1 to compare the improvements in the six-minute walk test (6MWT). The quality-of-life scores substantially improved in LVAD patients and the 6MWT showed the same functional recovery as in HTx patients from T0 to T1. After T1, numerous LVAD patients withdrew from the study. However, the 6MWT outcome increased further from T1 to T3, with a positive trend during the follow-ups. Hemoglobin and the ventilatory performance increased, and the psychological perception of heart-failure symptoms and pain further improved at T2. In conclusion, exercise-based rehabilitation programs provide similar beneficial effects in LVAD and HTx patients, without deterioration in LVAD patients up to 12 months after discharge.

Coping, Mood, Quality of Life, and Outcomes in Recipients of Left Ventricular Assist Devices: A Cluster Analysis.

OBJECTIVE: Left ventricular assist devices (LVADs) are increasingly used for temporary circulatory support until transplant or as destination therapy for patients with end-stage heart failure. Understanding patients' attitudes and resources is crucial to support them. METHODS: Sixty-one LVAD recipients (55 [10] years, 10% women, 15% destination therapy) participating in cardiac rehabilitation (CR) postimplant underwent assessment of coping styles (Coping Orientation for Problem Experiences), quality of life (Medical Outcomes Study Short-Form 36, Minnesota Living with Heart Failure Questionnaire), and mood (Hospital Anxiety and Depression Scale). RESULTS: Cluster analysis identified two homogeneous groups: C1 (n = 18) patients had higher anxiety (9.6 [5.0] versus 4.0 [2.7], p < .001), depression (10 [3.0] versus 4 [2.7], p < .001), and avoidant coping (29 [5.2] versus 21.2 [3.8], p < .001) scores and worse quality of life (Short-Form 36 of the Medical Outcomes Study Physical Component Scale 31 [5.3] versus 35.6 [6.9], p < .001; Mental Component Scale 34.3 [6.8] versus 50.3 [8], p < .001; MLHFQ physical 26 [7.2] versus 13.9 [8.2], p < .001; emotional 17.7 [3.4] versus 3.86 [3.2], p < .001) than C2 participants (n = 43). During 31 (15-54) months, 20 patients (33%) died. By Cox multivariable analysis, after adjustment for age, sex, Interagency Registry for Mechanically Assisted Circulatory Support level at surgery, and meters walked during 6 minutes at CR discharge, C1 was associated with mortality (hazard ratio = 2.858; 95% confidence interval = 1.102-7.408, p = .031; model χ = 7.286, df = 5, p = .20). Survival was 44% in C1 and 77% in C2 (log-rank p = .033). CONCLUSIONS: Among patients discharged from CR after LVAD implant, one third show a profile characterized by worse perceived quality of life, mood disorders, and dysfunctional coping that is associated with long-term mortality, and these factors are potential targets for post-LVAD intensive support.

Psychological Profile in Coronary Artery By-Pass Graft Patients vs. Valve Replacement Patients Entering Cardiac Rehabilitation after Surgery.

Anxiety and depression are thought to influence the genesis of ischemic diseases and not of valvular diseases, but little is known on the psychological profile of cardiac patients after surgery. Aim of this study was to investigate differences in disease experience and mood between patients undergoing cardiac rehabilitation after coronary artery by-pass graft (CABG) or after valve replacement (VR). We studied 1,179 CABG and 737 VR patients who completed the Illness Behaviour Questionnaire and the Hospital Anxiety and Depression Scale after surgery. We tested the independent effect of the type of surgery by multivariate analysis and between-group differences in prevalence of clinically relevant scores. Relevant scores in the psychosomatic concern scale were more frequent in CABG than in VR patients. After correction by age, sex, education and marital status, scores of disease conviction and psychosomatic concern were higher in CABG patients, scores of denial were higher in VR patients. Unexpectedly, anxiety and depression scores did not differ between groups. Results suggest providing psychological support for anxiety and depression to both VR and CABG patients during cardiac rehabilitation, and planning differentiated interventions of cardiac rehabilitation and secondary prevention tailored to the specific psychological reactions of CABG and VR patients.

The Influence of Breathing on the Central Nervous System.

The functions of the diaphragm do not stop locally in its anatomy but affect the whole body system. The respiratory rhythm, directly and indirectly, affects the central nervous system (CNS). This article describes and reviews these influences, containing, for the first time, information on this subject in a single text. The ability of breath to move the brain mass and determine patterns of neural oscillation will be discussed. The role of the diaphragm in influencing motor expression and its effect on intracranial blood shifts in respiratory activity will also be discussed. It is known that the diaphragm can have multiple uses in improving the symptomatological picture of chronic diseases, but there is no current, concrete data on the effects that the rehabilitative training or manual approaches could have on the patient; in particular, on his/her cognitive and cerebral aspects in general.

Promotion of Home-Based Exercise Training as Secondary Prevention of Coronary Heart Disease: A PILOT WEB-BASED INTERVENTION.

BACKGROUND: Although cardiac rehabilitation (CR) is cost- effective in improving the health of patients with coronary heart disease (CHD), less than half of eligible CHD patients attend a CR program. Innovative web-based technologies might improve CR delivery and utilization. We assessed the feasibility and impact on functional capacity and secondary prevention targets of a long-term web-monitored exercise-based CR maintenance program. METHODS: Low- to moderate-risk CHD patients were recruited at discharge from inpatient CR after a coronary event or revascularization. We developed an interactive web-based platform for secure home individual access control, monitoring, and validation of exercise training. Of 86 eligible patients, 26 consented to participate in the study intervention (IG). Using a quasi-experimental design, we recruited in parallel 27 eligible patients, unavailable for regular web monitoring, who consented to a follow-up visit as usual care (UC). RESULTS: Among IG, active daily data transmission was 100% during month 1, 88% at month 3, and 81% at 6 months, with sustained improvement in self-reported physical activity beginning with the first week after discharge from inpatient CR (2467 [1854-3554] MET-min/wk) to month 3 (3411 [1981-5347] MET-min/wk, P = .019). Both groups showed favorable changes over time in lipid profile, ventricular function, distance walked in 6 min, and quality of life. At 6 mo, IG achieved a significantly higher proportion of cardiovascular risk factor targets than UC (75 ± 20% vs 59 ± 30%, P = .029). CONCLUSIONS: Our web-based home CR maintenance program was feasible, well-accepted, and effective in improving physical activity during 6 mo and achieved higher overall adherence to cardiovascular risk targets than UC.

Osteopathic Manipulative Treatment Improves Heart Surgery Outcomes: A Randomized Controlled Trial.

BACKGROUND: Controlling sternal pain after heart surgery is important to reduce the risk of postoperative complications, but pain is often undertreated because of contraindications and side effects of analgesic drugs. Recently, osteopathic manipulative treatment (OMT) was demonstrated to reduce pain in different clinical contexts, suggesting its potential utility after cardiac surgery. The aim of this open-label, controlled study is to assess whether OMT contributes to sternal pain relief and improves postoperative outcomes. METHODS: Eighty post-sternotomy adult inpatients were randomly allocated one to one to receive a standardized cardiorespiratory rehabilitation program alone (control group) or combined with OMT. Pain intensity and respiratory functional capacity were quantified by the Visual Analogue Scale score and by a standardized breathing test, at the start and end of rehabilitation. RESULTS: At the start of rehabilitation, the control group and the OMT group had similar Visual Analogue Scale median scores (controls 4, interquartile range [IQR]: 2 to 5; OMT 4, IQR: 3 to 5; p = not significant) and mean inspiratory volumes (controls 825 ± 381 mL; OMT 744 ± 291 mL; p = not significant). At the end of rehabilitation, the OMT group had a lower Visual Analogue Scale median score (controls 3, IQR: 2 to 4; OMT 1, IQR: 1 to 2; p < 0.01) and higher mean inspiratory volume (controls 1,400 ± 588 mL; OMT 1,781 ± 633 mL; p < 0.01). The analgesic drug intake was similar in the two groups. The hospitalization was shorter in the OMT group than in the control group (19.1 ± 4.8 versus 21.7 ± 6.3 days; p < 0.05). CONCLUSIONS: The combination of standard care with OMT is effective in inducing pain relief and functional recovery, and significantly improves the management of patients after heart surgery with sternotomy.

Quality of life and emotional distress early after left ventricular assist device implant: a mixed-method study.

Patients who temporarily or permanently rely on left ventricular assist devices (LVADs) for end-stage heart failure face complex psychological, emotional, and relational problems. We conducted a mixed-method study to investigate quality of life, psychological symptoms, and emotional and cognitive reactions after LVAD implant. Twenty-six patients admitted to cardiac rehabilitation were administered quality of life questionnaires (Short Form 36 of the Medical Outcomes Study and Minnesota Living with Heart Failure Questionnaire), the Hospital Anxiety and Depression Scale, and the Coping Orientation for Problem Experiences inventory, and underwent three in-depth unstructured interviews within 2 months after LVAD implant. Quality of life assessment (Short Form 36) documented persistently low physical scores whereas mental component scores almost achieved normative values. Clinically relevant depression and anxiety were observed in 18 and 18% of patients, respectively; avoidant coping scores correlated significantly with both depression and anxiety (Pearson correlation coefficients 0.732, P < 0.001 and 0.764, P < 0.001, respectively). From qualitative interviews, factors that impacted on LVAD acceptance included: device type, disease experience during transplant waiting, nature of the assisted organ, quality of patient-doctor communication, the opportunity of sharing the experience, and recipient's psychological characteristics. Quality of life improves early after LVAD implant, but emotional distress may remain high. A multidimensional approach that takes into account patients' psychological characteristics should be pursued to enhance LVAD acceptance.

Gender differences in illness behavior after cardiac surgery.

PURPOSE: Differences in the ways male and female patients confront their illness after cardiac surgery may contribute to previously observed gender differences in the outcomes of cardiac rehabilitation. The aim of this cross-sectional study was to verify whether there are gender-related differences in illness behavior (IB) soon after cardiac surgery and before entering cardiac rehabilitation. METHODS: Patients (N = 1323) completed the IB Questionnaire and Hospital Anxiety and Depression Scale (HADS) 9 ± 5 (mean ± SD) days after cardiac surgery. The scores were tested for gender differences in score distributions (Mann-Whitney U test) and in prevalence of clinically relevant scores (the Pearson χ² test). Multivariate regression analyses were made with IB Questionnaire and HADS scores as independent variables, and gender, age, education, marital status, and type of surgery as predictors. RESULTS: Denial was significantly (P < .01) prevalent among the men (3.6 ± 1.4) versus women (3.2 ± 1.6), whereas disease conviction (men = 2.1 ± 1.5, women = 2.5 ± 1.6), dysphoria (men = 1.5 ± 1.5, women = 2.0 ± 1.6), anxiety (men = 6.0 ± 3.6, women = 6.9 ± 3.9), and depression (men = 5.3 ± 3.8, women = 6.5 ± 4.0) were significantly more prevalent among women. The prevalences of clinically relevant scores for disease conviction, anxiety, and depression were also significantly higher in women. Multivariate analysis showed that gender predicted these scores even after the removal of confounders. CONCLUSIONS: Gender differences exist in denial, disease conviction, and dysphoria, probably depending on the culturally assigned roles of men and women. As these aspects of IB may compromise treatment compliance and the quality of life, the efficacy of cardiac rehabilitation programs might be improved taking into account the different prevalences in men and women.

Psychological profiles derived by cluster analysis of Minnesota Multiphasic Personality Inventory and long term clinical outcome after coronary artery by pass grafting.

BACKGROUND: To evaluate the psychological characteristics of coronary heart disease (CHD) patients after coronary artery bypass grafting (CABG) by cluster analysis of Minnesota Multiphasic Personality Inventory (MMPI-2) questionnaires and to assess the impact of the profiles obtained on long-term outcome. METHODS: 229 CHD patients admitted to cardiac rehabilitation filled in self-administered MMPI-2 questionnaires early after CABG. We assessed the relation between MMPI-2 profiles derived by cluster analysis, clinical characteristics and outcome at 3-year follow-up. RESULTS: Among the 215 patients (76% men, median age 66 years) with valid criteria in control scales, we identified 3 clusters (G) with homogenous psychological characteristics: G1 patients (N = 75) presented somatoform complaints but overall minimal psychological distress. G2 patients (N=72) presented type D personality traits. G3 subjects (N=68) showed a trend to cynicism, mild increases in anger, social introversion and hostility. Clusters overlapped for clinical characteristics such as smoking (G1 21%, G2 24%, G3 24%, p ns), previous myocardial infarction (G1 43%, G2 47%, G3 49% p ns), LV ejection fraction (G1 60 [51-60]; G2 58 [49-60]; G3 60 [55-60], p ns), 3-vessel-disease prevalence (G1 69%, G2 65%, G3 71%, p ns). Three-year event rates were comparable (G1 15%; G2 18%; G3 15%) and Kaplan-Meier curves overlapped among clusters (p ns). CONCLUSIONS: After CABG, the interpretation of MMPI-2 by cluster analysis is useful for the psychological and personological diagnosis to direct psychological assistance. Conversely, results from cluster analysis of MMPI-2 do not seem helpful to the clinician to predict long term outcome.

Functioning and disability in ischaemic heart disease.

OBJECTIVE: To describe functioning and disability in patients with stable ischaemic heart disease (IHD) according to the model endorsed by the International Classification of Functioning Disability and Health (ICF). DESIGN: Adult patients with IHD undergoing rehabilitation were consecutively enrolled. The ICF checklist and the WHO Disability Assessment Schedule II (WHO-DAS II) were administered in individual sessions. Patients' clinical status was described following NYAH criteria (New York Heart Association). Descriptive analyses were performed to report on clinical variables and WHO-DAS II scores. ICF categories reported as a problem by more than 20% of patients were described in detail. RESULTS: One hundred patients (mean age 62.9; 91% males, 71% in NYHA class II) were enrolled. Mean WHO-DAS II score was 23.9, and the most severe limitations are reported in life activities, getting around and in participation to social situations. A total of 30 ICF categories reached the threshold of 20%, 17 Body Functions and Structures, 13 Activities and Participation. CONCLUSIONS: ICF application in patients with IHD enables to enlarge the perspective on their health status, and provide useful information to follow the healthcare process from the acute setting to the outpatient management.

Psychological disorders after coronary artery by-pass surgery: a one-year prospective study.

BACKGROUND: Coronary artery by-pass surgery (CABG) is often followed by anxiety and depression that require early identification in order to provide adequate psychological support. The predictive role of tests administered soon after CABG on long-term psychological outcomes has been only incompletely explored. AIM, DESIGN AND METHODS: Aim of this study was to assess post-operative and 12-month persistence of psychological disorders by means of the Minnesota Multiphasic Personality Inventory (MMPI-2) and the depression and state and trait anxiety scales of the Cognitive Behavioural Assessment (CBA-2.0) in 118 male patients admitted to cardiac rehabilitation after CABG. RESULTS: Early after CABG we observed a high prevalence of depression (11.8% by MMPI-2 and 12.7% by CBA) and state anxiety (23.5%). At 1-year the MMPI-2 scale D indicated stable mean score and high scores at entry were predictive of persistent depression. Conversely the CBA-2.0 scale QD score significantly decreased (from 3.86 +/- 3.19 to 2.91 +/- 3.45, p = 0.017). Also ST1 state anxiety significantly decreased (from 35.17 +/- 6.95 to 32.55 +/- 6.72, p = 0.003) whereas ST2 trait anxiety was stable. We found no association between psychometric results and ventricular function, number of grafts or time since diagnosis of coronary artery disease. CONCLUSIONS: State anxiety and depression by CBA significantly decreased 1-year after CABG; conversely trait anxiety and depression, investigated by MMPI-2, a more specific personality questionnaire, were stable. High scores for the depression in the scale D of MMPI-2 early after CABG seem to be predictive of the persistence of the disorder at 1-year.
