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.

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.

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.

Prevalence and 1-year prognosis of transient heart failure following coronary revascularization.

The occurrence of heart failure during the whole pre-discharge course of coronary revascularization, as far as its influence on subsequent prognosis, is poorly understood. The present study examined the effect of transient heart failure (THF) developing in the acute and rehabilitative phase on survival after coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI). Patients in the Italian survey on cardiac rehabilitation and secondary prevention after cardiac revascularization (ICAROS) were analyzed for THF, the latter being defined either as signs and symptoms consistent with decompensation or cardiogenic shock. ICAROS was a prospective, multicenter registry of 1,262 consecutive patients discharged from 62 cardiac rehabilitation (CR) facilities, providing data on risk factors, lifestyle habits, drug treatments, and major cardiovascular events (MACE) during a 1-year follow-up. Records were linked to the official website of the Italian Association of Cardiovascular Prevention and Rehabilitation (GICR-IACPR). The overall prevalence of pre-discharge THF was 7.6%, with 69.8% of cases in acute wards, 22.9% during CR, and 7.3% in both settings. THF affected more frequently patients with chronic cardiac condition (42.7 vs. 30.6%; p < 0.05), age ≥75 years (33.3 vs. 23.1%; p < 0.005), COPD (19.8 vs. 12.3%; p < 0.05), and chronic kidney disease (17.7 vs. 7%; p < 0.001). After discharge, THF patients showed good maintenance rates of RAAS modulators (90.6%) and beta-blockers (83.3%), while statin therapy significantly decreased from 81.3 to 64.6% (p < 0.05). The pursuit of secondary prevention targets, as far as self-reported drug adherence, was not different among groups. Patients with THF had increased 1-year mortality (8.3 vs. 1.6%, p < 0.001). Moreover, THF independently predicted adverse outcome with OR for recurrent events (mainly further episodes of decompensation) of 2.4 (CI 1.4-4.3). Patients who experienced THF after coronary revascularization had increased post-discharge mortality and cardiovascular events. Hemodynamic instability, rather than recurrent myocardial ischemia, seems to be linked with worse prognosis.

Effective secondary prevention through cardiac rehabilitation after coronary revascularization and predictors of poor adherence to lifestyle modification and medication. Results of the ICAROS Survey.

BACKGROUND AND AIM: Secondary prevention is a priority after coronary revascularization. We investigate the impact of a cardiac rehabilitation (CR) program on lifestyle, risk factors and medication modifications and analyze predictors of poor behavioral changes and events in patients after coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). METHODS: Multicenter (n=62), prospective, longitudinal survey in post-CABG or -PCI consecutive patients after a comprehensive CR program. Cardiac risk factors, lifestyle habits, medication and 1 year cardiovascular events were collected. Logistic regression analyzed the association between risk factors, events and predictors of non-adherence to treatment and lifestyle. RESULTS: At 1 year, of the 1262 patients (66 ± 10 years, CABG 69%, PCI 31%), 94% were taking antiplatelet agents (vs. 91.8% at CR admission and 91.7% at CR discharge, p=ns), 87% statins (vs. 67.5%, p<.0001, and 86.3%, p=ns), 80.7% beta-blockers (vs. 67.4%, p<.0001, and 88.8%, p=ns), and 81.1% ACE inhibitors (vs. 57.5% p<.0001, and 77.7%, p=ns). 89.9% of the patients showed good adherence to treatment, 72% adhered to diet and 51% to exercise recommendations; 74% of smokers stopped smoking. Younger age was predictive of smoking resumption (OR 8.9, CI 3.5-22.8). Pre-event sedentary lifestyle (OR 3.3, CI 1.3-8.7) was predictive of poor diet. Older patients with comorbidity (OR 3.1; CI, 1.8-5.2) tended to persist in sedentary lifestyle and discontinue therapy and diet recommendations. Age, diabetes, smoking and PCI indication were predictors of recurrent CV events which occurred in 142 patients. 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 benefit of secondary prevention. Several clinical characteristics may predict poor behavioral changes.

[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.

Gender differences in cardiac rehabilitation programs from the Italian survey on cardiac rehabilitation (ISYDE-2008).

PURPOSE: In recent years epidemiological and clinical evidence has shown gender disparities in several aspects of cardiovascular disease. Aim of this study was to identify gender differences in the clinical profile and management of patients admitted to cardiac rehabilitation (CR) programs. POPULATION: Patients enrolled in the ISYDE-2008 survey were considered. RESULTS: The ISYDE-2008 survey enrolled 2281 patients; 604 (26.5%) were women. Compared to men, women were older (mean age 70.8 ± 11.5 versus men's 65.6 ± 11.5 years), had less traditional risk factors (low cardiovascular risk profile in 45.3% of women and 38.0% of men, p=0.003), were more frequently admitted after valvular surgery and heart failure, but less for post-acute myocardial infarction and post-by-pass procedure. Women were more frequently admitted to an in-hospital rehabilitation program. Women showed a more complicated acute and rehabilitative course, with 63.2% of them having at least one complication during acute-phase, compared to 52.5% of men, and 48.3% during rehabilitation, compared to 35.0% of men (p<0.0001). During rehabilitation, women underwent exercise tests less frequently, except for the 6-minute walking test. At discharge, women received ACE-inhibitors/ARBs, ß-blockers, statins, omega-3 fatty acids, antiplatelet agents less frequently, but more frequently digoxin, amiodarone, diuretics, oral anticoagulants, insulin and anti-depressive drugs. The duration of the rehabilitation program was longer for women. Mortality was very low in the entire population. CONCLUSIONS: Women are less frequently admitted to CR than men. They are older and show a greater cardiovascular burden. Women are more likely to be enrolled in CR after valvular surgery and heart failure than men.

Postoperative anemia and exercise tolerance after cardiac operations in patients without transfusion: what hemoglobin level is acceptable?

BACKGROUND: Restrictive transfusion strategies have been suggested for cardiac surgical patients, leading to various degrees of postoperative anemia. This study investigates the exercise tolerance during rehabilitation of cardiac surgical patients who did not receive transfusions, with respect to their level of postoperative anemia. METHODS: This observational study started in January 2010 and ended in May 2010 in 2 rehabilitation hospitals and 2 large-volume cardiac surgical hospitals. The study population was 172 patients who did not receive transfusions during cardiac surgical operations with cardiopulmonary bypass and subsequently followed a rehabilitation program in 1 of the 2 rehabilitation hospitals. No patient received a transfusion during the rehabilitation hospital stay. Exercise tolerance was measured using the 6-minute walk test at admission and discharge from the rehabilitation hospital. The level of anemia at admission to the rehabilitation hospital was tested as an independent predictor of exercise tolerance within a model inclusive of other possible confounders. RESULTS: Patients with values of hemoglobin less than 10 g/dL at admission to the rehabilitation institute had a significantly (p=0.007) worse performance on the 6-minute walk test than patients with higher values (258±106 vs 306±101 meters). This functional gap was completely recovered during a normal rehabilitation period. Other independent factors affecting exercise tolerance were age, sex, and albumin concentration. CONCLUSIONS: Postoperative anemia with hemoglobin levels of 8 to 10 g/dL is well tolerated in patients who have not received a transfusion and induces only a transient impairment of exercise tolerance.

Late postoperative atrial fibrillation after cardiac surgery: a national survey within the cardiac rehabilitation setting.

AIMS: The aims of this study were to determine the incidence and clinical predictors of new-onset and recurrent late postoperative atrial fibrillation (POPAF) in a large cohort of patients who underwent cardiac rehabilitation programs (CRPs) after discharge from surgery units, and the association between late POPAF and cardiovascular morbidity and mortality in the medium term. METHODS: The ISYDE and ICAROS registries were two multicenter, prospective studies carried out by the Italian Association for Cardiovascular Prevention, Rehabilitation and Epidemiology (IACPR-GICR), providing clinical information on consecutive patients completing CRP in 165 facilities. Patients following cardiac surgery were considered, with the exclusion of those with persistent POPAF at discharge from the surgery units. A total of 2256 patients following cardiac surgery were enrolled (isolated coronary surgery 62.9%, valve interventions 16%, combined surgery 21.1%). RESULTS: The mean age of patients was 67 ± 10 years, and the observation period 13 ± 20 days. During CRP, POPAF occurred in 241 (10.7%) patients, with 4.4% new-onset and 6.3% recurrent cases, respectively. In the logistic regression model, valve surgery (P < 0.05), a history of early POPAF (P < 0.001), and the presence of postoperative ventricular arrhythmias (P < 0.05) independently predicted the occurrence of late POPAF. Lack of prescription of cardioprotective drugs was not associated with late POPAF. Late POPAF increased the 1-year risk of cardiovascular events after CRP, mainly episodes of decompensated heart failure. CONCLUSION: A high level of suspicion for late POPAF, after discharge from surgery units, should be maintained due to the risk of occurrence, the low antiarrhythmic effect of common cardioprotective drugs and the impact on cardiovascular prognosis.

Cardiac rehabilitation in very old patients: data from the Italian Survey on Cardiac Rehabilitation-2008 (ISYDE-2008)--official report of the Italian Association for Cardiovascular Prevention, Rehabilitation, and Epidemiology.

BACKGROUND: Using data from the Italian SurveY on carDiac rEhabilitation-2008 (ISYDE-2008), this study provides insight into the level of implementation of cardiac rehabilitation (CR) in very old cardiac patients. METHODS: Data from 165 CR units were collected online from January 28 to February 10, 2008. RESULTS: The study cohort consisted of 2,281 patients (66.9 ± 11.8 years): 1,714 (62.4 ± 9.6 years, 78% male) aged<75 years and 567 aged ≥ 75 years (80.8 ± 4.5 years, 59% male). Compared with adults, a higher percentage of older patients were referred to CR programs after cardiac surgery or acute heart failure and showed more acute phase complications and comorbidity. Older patients were less likely discharged to home, more likely transferred to nursing homes, or discharged with social networks activation. Older patients had higher death rate during CR programs (odds ratio = 4.6; 95% confidence interval = 1.6-12.9; p = .004). CONCLUSION: The ISYDE-2008 survey provided a detailed snapshot of CR in very old cardiac patients.

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.

[Thromboprophylaxis against venous thromboembolism after coronary surgery: underevaluated, underused, or both?]. / La profilassi eparinica del tromboembolismo venoso dopo cardiochirurgia coronarica: poco studiata, poco utilizzata o entrambi?

Little evidence exists about the risk of venous thromboembolism after coronary artery bypass graft (CABG) surgery. According to available studies, about one fifth of CABG patients develop symptomatic or asymptomatic deep vein thrombosis, whereas less than 1% of patients suffer from clinically evident pulmonary embolism. Deep vein thrombosis and pulmonary embolism may influence the outcome of coronary revascularization in terms of morbidity and mortality in the short and medium-term, but unfortunately no clear consensus still exists regarding proper thromboprophylaxis measures. As the incidence of deep vein thrombosis and pulmonary embolism after CABG is similar to the incidence in patients undergoing general surgery, heparin prophylaxis could be considered targeted on patients' individual prothrombotic risk.

In this paper, the Italian Society of Cardiac Rehabilitation and Prevention (GICR) presents the third survey on the status of cardiac rehabilitation (CR) in Italy. The Italian SurveY on carDiac rEhabilitation 2008 (ISYDE 2008) is a multicenter, observational study aimed at identifying the number and characteristics of Italian CR facilities, both in terms of health operators and interventions. Clinical records of all patients consecutively discharged within the whole network--composed of up to 200 CR units--from January 28 to February 10, 2008 will also be reviewed for diagnosis of admission, comorbidities, rehabilitation programs, and drug therapy, in order to obtain a snapshot of current implementation strategies in daily clinical practice. The survey will adopt a web-based methodology for data provision and transmission. Preliminary results of the survey are expected in the late summer 2008.

[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.

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.

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.
