Iron deficiency from the standpoint of cardiac rehabilitation: novel therapeutic opportunities.

Anemia is one of the most frequent comorbidities found in patients with coronary artery disease and chronic heart failure (CHF) who are being followed in cardiac rehabilitation facilities. The more frequent type of anemia is caused by iron deficiency (IDA, iron-deficiency anemia): this review summarizes the state of the art of this topic. First of all, the mechanisms of IDA will be analyzed. Subsequently, a description of the main conditions where IDA can unfavorably affect the clinical course, and of its more frequent complications, will be presented (percutaneous interventions, heart surgery, CHF). Special attention will be paid in the description of anemia in the setting of CHF. To this regard, in recent years a relevant amount of research has been carried out, to determine whether treating anemia (either by directly stimulating erythropoiesis or by correcting iron deficiency by oral or intravenous route) is of any clinical and prognostic relevance in patients with CHF. The results of this research will, therefore, be summarized and critically discussed. Finally, we will outline the promising role of cardiac rehabilitation facilities and of its network of experts in the diagnosis, prognostic stratification, and treatment of anemia and iron deficiency.

[ICAROS (Italian survey on CardiAc RehabilitatiOn and Secondary prevention after cardiac revascularization): temporary report of the first prospective, longitudinal registry of the cardiac rehabilitation network GICR/IACPR]. / ICAROS (Italian survey on CardiAc RehabilitatiOn and Secondary prevention after cardiac revascularization): primo bilancio di una grande esperienza scientifica del network riabilitativo GICR/IACPR.

The Italian survey on CardiAc RehabilitatiOn and Secondary prevention after cardiac revascularization (ICAROS) was a multicenter, prospective, longitudinal survey carried out by the Italian Association on Cardiovascular Prevention and Rehabilitation (GICR/IACPR) in patients on completion of a CR program after coronary artery by pass grafting (CABG) and percutaneous coronary intervention (PCI). The aim was to evaluate in the short and medium-term: i) the cardioprotective drug prescription, modification and adherence; ii) the achievement and maintenance of recommended lifestyle targets and risk factor control and their association with cardiovascular events; iii) the predictors of non-adherence to therapy and lifestyle recommendations. The ICAROS results offers a portrait of the "real world" of clinical practice concerning patients after CABG and PCI, and stresses the need to improve secondary prevention care after the index event: many patients after revascularization leave the acute wards without an optimal prescription of preventive medication but the prescription of cardiopreventive drugs and risk factors control is excellent after completion of a CR program. Following CR, the maintenance of evidence-based drugs and lifestyle adherence at one year is fairly good as far as the target goals of secondary prevention are concerned, but to investigate the influence of CR on long-term outcome longer-term studies are required. Last, but not least, ICAROS shows that some characteristics (PCI as index event, living alone, poor eating habits or smoking in young age, and old age, in particular with comorbidities) may identify patients with poor behavioral modification in the medium-term follow-up and in these patients further support may be warranted. In conclusion, participation in CR results in excellent treatment after revascularization, as well as a good lifestyle and medication adherence at 1 year and provides further confirmation of the the benefit of secondary prevention.

[Standards and outcome measures in cardiovascular rehabilitation. Position paper GICR/IACPR]. / Requisiti e indicatori in cardiologia riabilitativa: documento di consenso del GICR/IACPR.

Despite major improvements in diagnostics and interventional therapies, cardiovascular diseases remain a major health care and socio-economic problem in Italy. Costs and resources required are increasing in close correlation to both the improved quality of care and to the population ageing. There is an overwhelming evidence of the efficacy of cardiac rehabilitation (CR) in terms of reduction in morbidity and mortality after acute cardiac events. CR services are by definition multi-factorial and comprehensive. Furthermore, systematic analysis and monitoring of the process of delivery and outcomes is of paramount importance. The aim of this position paper promoted by the Italian Association for Cardiovascular Prevention and Rehabilitation (GICR-IACPR) is to provide specific recommendations to assist CR staff in the design, evaluation and development of their care delivery organization. The position paper should also assist health care providers, insurers, policy makers and consumers in the recognition of the quality of care requirements, standards and outcome measure, quality and performance indicators, and professional competence involved in such organization and programs. The position paper i) include comprehensive CR definition and indications, ii) describes priority criteria based on the clinical risk for admission to both inpatient or outpatient CR, and iii) defines components and technological, structural and organizing requirements for inpatient or outpatient CR services, with specific indicators and standards, performance measures and required professional skills. A specific chapter is dedicated to the requirements for highly specialized CR services for patients with more advanced cardiovascular diseases.

Six-minute walking test after cardiac surgery: instructions for an appropriate use.

The 6-min walking test is a practical, simple, inexpensive test, which does not require any exercise equipment or advanced training. The test has been proposed both as a functional status indicator and as an outcome measure in various categories of patients (postmyocardial infarction, heart failure, postcardiac surgery) admitted to rehabilitation programs. The purpose of this study is to review the literature regarding the usefulness of 6-min walking test for the evaluation of patients entering a cardiac rehabilitation program early after cardiac/thoracic surgery. The test is feasible and safe, even in elderly and frail patients, shortly after admission to an in-hospital rehabilitation program. The results of the test is influenced by many demographic and psychological variables, such as age, sex (with women showing lower functional capacity), comorbidity (particularly diabetes mellitus, arthritis, and other musculoskeletal diseases), disability, self-reported physical functioning, and general health perceptions; contrasting data correlate walked distance with left ventricular ejection fraction. Practical suggestions for test execution and results interpretation in this specific clinical setting are given according to current evidence.

Italian survey on cardiac rehabilitation and secondary prevention after cardiac revascularization: ICAROS study. A survey from the Italian cardiac rehabilitation network: rationale and design.

In this paper, the Italian Association for Cardiac Prevention and Rehabilitation (GICR) presents the rationale and design of the "Italian survey on CArdiac RehabilitatiOn and Secondary prevention after cardiac revascularization (ICAROS)". The survey is a prospective, longitudinal, multicentric survey, with a on-line web-based data collection. Its design corresponds to the survey's goal, i.e. to describe accurately in the Italian cardiological setting, through a representative number of cardiac rehabilitation centers belonging to the GICR national network, the characteristics, content and effects in the medium term of cardiac rehabilitation (CRP) inpatient or outpatient programs offered to patients after coronary artery bypass (CABG) or percutaneous revascularization (PTCA). The primary aims of the study are: a) to define the principal clinical characteristics of patients who have undergone PTCA or CABG and have been admitted to a CRP program; b) to identify the components of the CRP programs in terms of diagnostic procedures and assessment tests performed, treatments administered, educational programs and physical exercise interventions employed; c) to identify and analyze drug treatments prescribed at discharge from the acute facility and those prescribed at the end of the CRP program; d) to verify the clinical outcome during the course of the CRP program and at 6 months and 1 year after the end of the post-acute CRP program, as well as patients' adherence to the prescribed pharmacological therapy and to the recommended life styles, and the achievement and maintenance of the targets in relation to the modifiable risk factors; e) to define the consumption of major healthcare resources (major cardiac events, hospital re-admission, emergency care access, specialist visits) during the first year following a CRP program. The survey population will consist of all patients consecutively discharged in the period November 3-30, 2008 at the end of an inpatient, day-hospital or outpatient CRP programme after CABG (isolated or associated to valve or ascending aorta surgery) or PTCA (rescue, primary or elective). There are no age, sex or other patient selection criteria. Based on ISYDE 2008 data analysis, we plan to recruit approximately 1300-1400 patients, 75% of whom with post CABG diagnosis and 25% with post PTCA diagnosis. Preliminary results of the survey are expected in the late winter 2009.

The Italian Survey on Cardiac Rehabilitation-2008 (ISYDE-2008). Part 3. National availability and organization of cardiac rehabilitation facilities. Official report of the Italian Association for Cardiovascular Prevention, Rehabilitation and Epidemiology (IACPR-GICR).

From January 28th to February 10th 2008, the Italian Association for Cardiovascular Prevention, Rehabilitation and Epidemiology (IACPR-GICR) conducted the ISYDE-2008 study, the primary aim of which was to take a detailed snapshot of cardiac rehabilitation (CR) provision in Italy--in terms of number and distribution of facilities, staffing levels, organization and setting--and compare the actual CR provision with the recommendations of national guidelines for CR and secondary prevention. The secondary aim was to describe the patient population currently being referred to CR and the components of the programs offered. Out of 190 cardiac rehabilitation centers existing in Italy in 2008, 165 (87%) took part in the study. On a national basis, there is one CR unit every 299,977 inhabitants: in northern Italy there is one CR unit every 263,578 inhabitants, while in central and southern Italy there is one every 384,034 and 434,170 inhabitants, respectively. The majority of CR units are located in public hospitals (59%), the remainder in privately owned health care organizations (41%). Fifty-nine percent are located in hospitals providing both acute and rehabilitation care, 32% are in specifically dedicated rehabilitation structures, while 8% operate in the context of residential long term care for chronic conditions. Almost three-quarters of CR units currently operating are linked to dedicated cardiology divisions (74%), 5% are linked to physical medicine and rehabilitation divisions, 2% to internal medicine, and 19% to cardiac surgery and other divisions. Inhospital care is provided by 62.4% of the centers; outpatient care is provided on a day-hospital basis by 10.9% of facilities and on an ambulatory basis by 20%. The CR units are led in 86% of cases by a cardiologist and in only 14% of cases by specialists in internal medicine, geriatrics, physical medicine and rehabilitation, pneumology or other disciplines. In terms of staffing, each cardiac rehabilitation unit has 4.0 +/- 2.7 dedicated physicians (range 1-16, mode 2), 10.1 +/- 8.0 nurses, 3.3 +/- 2.5 physiotherapists (range 0-20; 16% of services have no physiotherapist in the rehabilitation team), 1.5 +/- 0.8 psychologists, and a dietitian (present in 62% of CR units). Phase II CR programs are available in 67.9% of cases in residential (inpatient) and in 30.9% of cases in outpatient (day-hospital and ambulatory) settings. Phase III programs are offered by 56.4% of the centers in ambulatory outpatient regime, and on an at home basis by 4.8% with telecare supervision, 7.3% without. Long term secondary prevention follow up programs are provided by 42.4% of CR services.

[Organization of psychological activities in Italian cardiac rehabilitation and prevention. Survey on the implementation of guidelines for psychological activities in cardiac rehabilitation and prevention]. / Organizzazione delle attività di psicologia nelle strutture di cardiologia riabilitativa italiane. Indagine conoscitiva sulla implementazione delle linee guida per le attività di psicologia in cardiologia riabilitativa e preventiva.

UNLABELLED: The present study was developed as part of a comprehensive evaluation of the state of the art of knowledge and implementation of the Italian Guidelines for psychological activities in Cardiac Rehabilitation, published in 2003 by the Working Group of Psychology of the Italian Society of Cardiac Rehabilitation (GICR). METHODS: A questionnaire was designed to collect detailed information on facilities, organization, staffing level, professional background and activities carried out by psychologists working in Italian Cardiac Rehabilitation Units (CRU). Out of 144 Italian CRU (inventory 2004), 107 reported structured psychological programmes. The questionnaires were sent by conventional mail to the referring psychologist of these 107 CRU; they were invited to participate in the survey on a purely voluntary basis. RESULTS: Responses were received from 70 (65.4%) of 107 CRU. 55 CRU (79.8%) report a good knowledge of the published GL; 10.1% declare that the psychologists did not know the current GL. 84.5% consider the GL to be fully applicable, while 15.5% believe that they are only partly applicable. Psychological assessment is performed through clinical interview (94.3%) and psychometric tests (81.4%). 92.8% of the CRU use screening instruments in order to evaluate psychosocial risk factors, in particular anxiety and depression (64.3%). Quality of life (22.8%) and cognitive impairment (17.1%) are not routinely assessed. Educational interventions are planned in 87.1% of the CR programme and are extended to the family members (51%) as well as counselling (57%). Psychological programme includes smoking (56%) and eating behaviour (55%) group interventions. Stress management is routinely planned in 69% of the CRU. Psychological intervention tailored to individual needs of the patients is performed in 62.9% CRU. Written final reports are available in 88.6% cases. The follow-up is carried out by 48.6% of the CRU, 15.7% in a structured way. CONCLUSIONS. The survey shows wide discrepancies in the provision of psychological activities in Italian CRU. Nevertheless psychological assessment and interventions seem acceptably coherent with current national GL on CR.

Longitudinal profile of NT-proBNP levels in ischemic heart failure patients undergoing surgical ventricular reconstruction: The Biomarker Plus study.

BACKGROUND: Plasma concentrations of natriuretic peptides have been shown to predict prognosis in heart failure (HF) patients with left ventricle (LV) dysfunction. It is still unclear if measurements after cardiac surgery are associated with any effect on the outcome. We aimed to prospectively investigate the longitudinal profile of serial evaluations of N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in ischemic HF patients undergoing Surgical Ventricular Reconstruction (SVR) and how NT-proBNP levels at different time-points are associated with the outcome. METHODS: One hundred and forty-three patients (122 men, 64 ±â€¯9 years old) with post-infarction LV remodeling referred to our Center for SVR had an assessment of NT-proBNP levels before surgery and 6, 12 and 18 months after surgery. The analysis was performed using the logarithm of the biomarker and joint modeling of serial measurements through mixed models together with Cox regression to analyze time to event data. RESULTS: The average level of the biomarker decreased by about 50% during the first year after the operation. Time-varying NT-proBNP levels were associated with the hazard of: 1% increase in NT-proBNP during the follow-up was associated with 1.5% increase of the risk of the composite event (95% CI: 1.0%, 2.6%) and with 4.2% increase of the risk of death (95% CI: 2.2%, 8.2%). CONCLUSIONS: Serial profiles (either in increasing or in decreasing) at different time points are associated with a modulation of the risk of adverse events and, therefore, are important indicators for monitoring the evolution of the disease, even after cardiac surgery.

ISYDE-2008. Study presentation. The Italian survey on cardiac rehabilitation: a snapshot of current cardiac rehabilitation programmes and providers in Italy.

The Italian Society of Cardiac Rehabilitation and Prevention (GICR) has developed the ISYDE-2008 survey with the purpose to take a detailed snapshot in terms of number, distribution, facilities, staffing levels, organization, and programme details of CR units in Italy and to compare actual provision with the recommendation of National GL for CR and secondary prevention. The study will be carried out with a web-based questionnaire running on the GICR website in 2 weeks from Jan. 28 to Feb. 10, 2008. The first part of the questionnaire is designed to collect information on the institutional organization of the CR unit, on its location and functional relationships within the hospital, on the number of beds for inpatient CR units and hours of activity for outpatient and home-based services, on the composition of the core and multidisciplinary teams, and finally on the components of CR programmes. In the second part of the survey, CR directors will be requested to report for each patient discharged during the 2 weeks of the study, indications for admission to CR, time of enrolment, comorbidity, complications, risk profile, diagnostic procedures, exercise and educational programme, discharge modalities, treatment at discharge and follow-up schedule. More than 2300 pts are expected to enter in the survey, whose results depicting the status of CR in Italy will be available within April 2008.

Patterns and determinants of functional and absolute iron deficiency in patients undergoing cardiac rehabilitation following heart surgery.

Background Anaemia and iron deficiency are frequent following major surgery. The present study aims to identify the iron deficiency patterns in cardiac surgery patients at their admission to a cardiac rehabilitation programme, and to determine which perioperative risk factor(s) may be associated with functional and absolute iron deficiency. Design This was a retrospective study on prospectively collected data. Methods The patient population included 339 patients. Functional iron deficiency was defined in the presence of transferrin saturation <20% and serum ferritin ≥100 µg/l. Absolute iron deficiency was defined in the presence of serum ferritin values <100 µg/l. Results Functional iron deficiency was found in 62.9% of patients and absolute iron deficiency in 10% of the patients. At a multivariable analysis, absolute iron deficiency was significantly ( p = 0.001) associated with mechanical prosthesis mitral valve replacement (odds ratio 5.4, 95% confidence interval 1.9-15) and tissue valve aortic valve replacement (odds ratio 4.5, 95% confidence interval 1.9-11). In mitral valve surgery, mitral repair carried a significant ( p = 0.013) lower risk of absolute iron deficiency (4.4%) than mitral valve replacement with tissue valves (8.3%) or mechanical prostheses (22.5%). Postoperative outcome did not differ between patients with functional iron deficiency and patients without iron deficiency; patients with absolute iron deficiency had a significantly ( p = 0.017) longer postoperative hospital stay (median 11 days) than patients without iron deficiency (median nine days) or with functional iron deficiency (median eight days). Conclusions Absolute iron deficiency following cardiac surgery is more frequent in heart valve surgery and is associated with a prolonged hospital stay. Routine screening for iron deficiency at admission in the cardiac rehabilitation unit is suggested.

Myocardial Revascularization for Patients With Diabetes: Coronary Artery Bypass Grafting or Percutaneous Coronary Intervention?

Patients affected by diabetes usually have extensive coronary artery disease. Coronary revascularization has a prominent role in the treatment of coronary artery disease in the expanding diabetic population. However, diabetic patients undergoing coronary artery bypass grafting or percutaneous coronary intervention experience worse outcomes than nondiabetic patients. Several studies comparing coronary artery bypass grafting vs percutaneous coronary intervention in subgroups of diabetic patients demonstrated a survival advantage and fewer repeat revascularization procedures with an initial surgical strategy. This review summarizes the current state of evidence comparing the effectiveness and safety of coronary artery bypass grafting and percutaneous coronary intervention in diabetic patients.

[The Italian Survey on Cardiac Rehabilitation - 2013 (ISYDE.13-Directory): national availability and organization of cardiac rehabilitation facilities]. / Italian Survey on Cardiac Rehabilitation (ISYDE.13-Directory): report su strutture, organizzazione e programmi di cardiologia riabilitativa in Italia.

BACKGROUND: The Italian Association for Cardiovascular Prevention, Rehabilitation and Epidemiology (GICR-IACPR) and the Italian Society of Cardiologists of Accredited Hospitals (SICOA) developed the ISYDE.13 survey with the purpose to take a detailed snapshot of number, distribution, facilities, staffing levels, organization, and program details of cardiac rehabilitation (CR) units in Italy. METHODS: The study was carried out using a web-based questionnaire running on the GICR-IACPR website for 4 weeks from September 2 to 29, 2013. RESULTS: Out of 221 CR centers existing in Italy (+14% vs 2008), 191 (86%) participated in the survey. On a national basis, there is a CR unit every 268 852 inhabitants. The majority of CR units are located in public hospitals (57.1%), the remaining 42.9% in private hospitals; 130 CR centers (68%) provide inpatients care and account for 3527 beds (5.9 per 100 000 inhabitants): of these 374 are day-hospital beds and 408 are sub-intensive beds. Forty-one of the Italian in-hospital CR centers offer also outpatient programs and 61 centers (32%) offer only outpatient CR programs; 131 of the CR units (68.6%) are linked to dedicated cardiology divisions and in 77% of cases the head is a cardiologist. Home-based programs are offered by 9 centers (4.7%) and CR programs with telecare supervision by 16 (8.4%). Long-term secondary prevention follow-up programs are provided by 94 of CR services (49.2%). During one week of activity, the 191 centers completed 1335 inpatient CR programs and 971 outpatient CR programs. According to these data, it may be assumed that in Italy approximately 100 000 patients are referred annually to CR programs. CONCLUSIONS: ISYDE.13 showed an incremental trend of CR provision in Italy, particularly in outpatient programs. However, at present, the national network of CR units covers only one third of the potential requirements defined by current secondary prevention recommendations.

Incidence and clinical presentation of myocardial ischemia in patients with chronic CAD in Italy: the ISPICA survey study.

AIM: This survey study was performed to provide an overall picture on the incidence of symptoms, with or without typical angina, in the real-life clinical practice and to identify clinical factors associated with atypical presentations in an unselected population of consecutive outpatients with chronic coronary artery disease (CAD). METHODS: Thirty-six cardiology units located in different geographic areas of Italy enrolled a total of 1475 outpatients (73.6% men and 26.3% women; mean age 71 ±â€Š10 and 67 ±â€Š9 years in men and women, respectively) with a documented diagnosis of chronic CAD. Each patient underwent a medical history, with a detailed investigation as to the presence of typical angina or ischemic equivalents defined as sensation of chest pressure, or arm, neck, or jaw pain. RESULTS: At admission, symptoms suggesting ischemic episodes were reported by 24.4% of patients. After an in-depth medical history collection by the specialist, the prevalence of combined typical or atypical myocardial ischemic episodes was ascertained in 39.3% of the overall population.Typical angina was reported by 13.6% of men and 22.7% of women (P < 0.0001), whereas ischemic equivalents were present in 7.3 and 12.9% of male and female patients, respectively (P < 0.001). Previous coronary artery bypass grafting (CABG; P < 0.001) and fewer medical visits by cardiologists (P = 0.02) were independent predictors of atypical presentations. CONCLUSION: The ISPICA study shows that in an Italian population of real-world patients with chronic CAD, ischemic episodes, with both typical and atypical presentation, are still present in nearly 50% of patients, despite optimal medical therapy, and that atypical presentations of angina are linked to fewer visits by specialists and previous CABG. These findings would suggest to encourage patients with chronic CAD and general practitioners to consider more frequent cardiology specialist visits and to take into account the possibility of atypical presentations, particularly in patients with previous CABG.

Slow breathing increases arterial baroreflex sensitivity in patients with chronic heart failure.

BACKGROUND: It is well established that a depressed baroreflex sensitivity may adversely influence the prognosis in patients with chronic heart failure (CHF) and in those with previous myocardial infarction. METHODS AND RESULTS: We tested whether a slow breathing rate (6 breaths/min) could modify the baroreflex sensitivity in 81 patients with stable (2 weeks) CHF (age, 58+/-1 years; NYHA classes I [6 patients], II [33], III [27], and IV [15]) and in 21 controls. Slow breathing induced highly significant increases in baroreflex sensitivity, both in controls (from 9.4+/-0.7 to 13.8+/-1.0 ms/mm Hg, P<0.0025) and in CHF patients (from 5.0+/-0.3 to 6.1+/-0.5 ms/mm Hg, P<0.0025), which correlated with the value obtained during spontaneous breathing (r=+0.202, P=0.047). In addition, systolic and diastolic blood pressure decreased in CHF patients (systolic, from 117+/-3 to 110+/-4 mm Hg, P=0.009; diastolic, from 62+/-1 to 59+/-1 mm Hg, P=0.02). CONCLUSIONS: These data suggest that in patients with CHF, slow breathing, in addition to improving oxygen saturation and exercise tolerance as has been previously shown, may be beneficial by increasing baroreflex sensitivity.

Contrast-enhanced magnetic resonance imaging assessment of scar size in patients with chronic myocardial infarction.

BACKGROUND: In the assessment of myocardial infarction (MI) mass, contrast-enhanced magnetic resonance imaging (CE-MRI) is comparable to single-photon emission computed tomography (SPECT). The aim of the present study was to determine whether the MI area, as assessed at CE-MRI and SPECT, is comparable to mass evaluation. We also compared CE-MRI and SPECT estimates of the MI area with functional evaluations made at echocardiography and kinetic MRI (cine-MRI). METHODS: We used a 1.0 Tesla MRI scanner and an inversion-recovery turboFLASH sequence, a tomographic gamma-camera and second-harmonic ultrasound systems. Two blinded operators assessed the extent of scarring, expressed as a percentage of the whole left ventricle (LV), using a 16-segment model. We studied 55 consecutive patients with a clinically stable healed MI (50 Q wave, 5 non-Q wave). RESULTS: The scar mass was 19+/-23% of the LV at CE-MRI and 21+/-25% at SPECT; the scar area was 29+/-23% of the LV at CE-MRI, 41+/-28% at SPECT, 29+/-31% at cine-MRI, and 32+/-29% at echocardiography. The Bland-Altman bias between CE-MRI and SPECT mass estimations was -2% of the LV with a+/-23% limit of agreement (LOA), while the bias between the area assessments was -12% with a+/-42% LOA. Bias between CE-MRI and functional evaluation by cine-MRI and echocardiography was 0% with a+/-39% LOA and -3% with a+/-36% LOA respectively. Comparing SPECT with cine-MRI and echocardiography the bias was 12% with a+/-52% LOA and 9% with a+/-56% LOA respectively. CONCLUSIONS: CE-MRI has proved to be comparable to SPECT in the assessment of the healed MI mass. Conversely, a high systematic error (high bias and LOA) renders CE-MRI and SPECT assessments of the MI area incomparable. Similarly (high bias and/or LOA) CE-MRI and SPECT estimations of the MI area cannot be compared with functional evaluation by echocardiography or cine-MRI.

Is physical training contraindicated in patients with deep vein thrombosis during cardiac rehabilitation?

Deep vein thrombosis is a potential complication in patients admitted to cardiac rehabilitation programs after acute coronary syndromes, episodes of acute congestive heart failure, and cardiac revascularization. A common clinical problem in these patients is to decide whether to start or continue physical training or not, given the risk of pulmonary embolism. Until definite evidence becomes available, careful patient selection and inpatient supervision may avoid the a priori withdrawal of such an important core component of cardiac rehabilitation programs.

[A new test (VITTORIO Test) for functional fitness assessment in rehabilitation after cardiac surgery]. / Un nuovo test (VITTORIO Test) per la valutazione dell'efficienza fisica in soggetti ammessi a programmi di riabilitazione dopo intervento di chirurgia cardiaca.

An adequate assessment of physical function (PF) in Cardiac Rehabilitation (CR) plays a central role in early detection of physical limitations. Traditionally exercise tolerance has been used as an indicator of overall PF. However exercise tolerance has been shown to poorly predict patients' ability to perform daily-life activities. The goal of the present study is to evaluate a new test, named VITTORIO TEST, for assessing various component of daily activities among patients in CR after cardiac surgery. VITTORIO test consists in 8 items that assess lower and upper extremity strength and flexibility, agility, dynamic balance, aerobic capacity. 500 patients (359 males; 141 females) admitted to CR programs following cardiac surgery (349 coronary artery bypass surgery; 151 valvular surgery) were enrolled in the study. They were evaluated with an initial test (T1) (10.7 +/- 6.3 days after cardiac surgery) and a final test (T2) after an in-hospital intensive training program (mean length 16.8 +/- 6.6 days) consisting in stretching, large muscle group and aerobic activity, resistance exercises. Statistical analysis showed a significant improvement of all items at the end of the rehabilitation program. Old patients (>70 years) and particularly females demonstrate exercise improvement comparable to that of younger subjects especially regards lower extremity strength and aerobic capacity. VITTORIO test is inexpensive, simple and easy to perform by the patient. Through the identification and the measurement of different aspects of physical disability, it allows a personalized rehabilitation exercise program. It could be used as an outcome measure of CR programs.

[ISYDE-Psi first step of the implementation of guidelines for psychology activities in cardiac rehabilitation and prevention. Italian SurveY on CarDiac REhabilitation-Psychology]. / ISYDE-Psi prima fase dell'implementazione delle linee guida per le attività di psicologia in cardiologia riabilitativa e preventiva. Italian SurveY on CarDiac REhabilitation-Psychology.

The Italian SurveY on CarDiac REhabilitation-Psychology (ISYDE-Psi) was developed, in line with the indications of the Italian National Guidelines Program, as part of a project to implement and apply the guidelines for psychology interventions in cardiac rehabilitation and prevention published in 2003. The Task Force on Psychological Interventions in Cardiac Rehabilitation conducted this pilot survey of the existing situation of Psychology in order to prepare the ground for implementation of the guidelines through interactive training. As part of the evaluation of training requirements a questionnaire was elaborated to gather information on the models of organization of and activities carried out by psychologists working in the surveyed cardiac rehabilitation facilities. Data collection for ISYDE-Psi terminated at the end of March 2005, with replies from 68/107 (63.6%) structures. In the light of this response, the Task Force has developed a training project for psychologists working in cardiac rehabilitation, sponsored by the Italian Council of Psychologists, that will be implemented in different regions of the country with the aim of disseminating the guidelines and promoting their correct application despite the existing regional disparities in organization.

Clinical characteristics and course of patients with diabetes entering cardiac rehabilitation.

BACKGROUND: Using data from the Italian SurveY on carDiac rEhabilitation (ISYDE-2008), this study provides insight into the level of implementation of Cardiac Rehabilitation (CR) in patients with diabetes. METHODS: Data from 165 CR units were collected online from January 28th to February 10th, 2008. RESULTS: The study cohort consisted of 2281 patients (66.9 ± 12 yrs); 475 (69.7 ± 10 yrs, 74% male) patients with diabetes and 1806 (66.2 ± 12 yrs, 72% male) non-diabetic patients. Compared to non-diabetic patients, patients with diabetes were older and showed more comorbidity [myocardial infarction (32% vs. 19%, p < 0.0001), peripheral artery disease (10% vs. 5%, p < 0.0001), chronic obstructive pulmonary disease (20% vs. 11%, p < 0.0001), chronic kidney disease (20% vs. 6%, p < 0.0001), and cognitive impairment (5% vs. 2%, p = 0.0009), respectively], and complications during CR [re-infarction (3% vs. 1%, p = 0.04), acute renal failure (9% vs. 4%, p < 0.0001), sternal revision (3% vs. 1%, p = 0.01), inotropic support/mechanical assistance (7% vs. 4%, p = 0.01), respectively]; a more complex clinical course and interventions with less functional evaluation and a different pattern of drug therapy at hospital discharge. Notably, in 51 (3%) and in 104 (6%) of the non-diabetic cohort, insulin and hypoglycemic agents were prescribed, respectively, at hospital discharge from CR suggesting a careful evaluation of the glycemic metabolism during CR program, independent of the diagnosis at the admission. Mortality was similar among diabetic compared to non-diabetic patients (1% vs. 0.5%, p = 0.23). CONCLUSIONS: This survey provided a detailed overview of the clinical characteristics, complexity and more severe clinical course of diabetic patients admitted to CR.

Distance walked in the 6-minute test soon after cardiac surgery: toward an efficient use in the individual patient.

STUDY OBJECTIVES: To describe the results of the 6-min walking test performed on admission to an intensive rehabilitation program after cardiac surgery and to develop, through an algorithm based on a few clinical indicators, reference tables in order to apply distance walked values more efficiently in the individual patient at his/her entry into a cardiac rehabilitation program. SETTING: Intensive cardiac rehabilitation units. PATIENTS AND INTERVENTION: A total of 2,555 consecutive patients admitted between January 2001 and December 2002 to the Cardiac Rehabilitation Department of the S. Maugeri Foundation early after cardiac surgery performed a 6-min walking test within the fourth day of hospital admission. RESULTS: The mean walked distance was 296 +/- 111 m (+/- SD). At multiple regression analysis, age, sex, and comorbidity were independent predictors of walking test performance. The left ventricular ejection fraction only influenced the walked distance in men. Starting from these variables, we propose an algorithm and specific reference tables. CONCLUSIONS: Reference values for gender-, age-, comorbidity-, and systolic function-related test performance in patients after cardiac surgery at the beginning of the rehabilitative phase are provided. Once a new patient has been categorized through simple parameters, the actual distance walked could be compared with the matched reference value, thus making the interpretation of the result more efficient. The walked distance might be used to define different levels of disability and to personalize therapeutic exercise prescriptions.
