Cardiac rehabilitation (CR) is the subspecialty of clinical cardiology dedicated to the treatment of cardiac patients, early and in the long term after an acute event. The aim of CR is to improve both quality of life and prognosis through prognostic stratification, clinical stabilization and optimization of therapy (pharmacological and non), management of comorbidities, treatment of disability, as well as through the provision and reinforcement of secondary prevention interventions and maintenaince of adherence to treatment. The mission of CR has changed over time. Once centered on the acute phase, aimed primarily at short-term survival, the healthcare of cardiac patients now increasingly involves the chronic phase where the challenge is to guarantee continuity and quality of care in the medium and long-term. The aim of the present position paper is to provide the state-of-the-art of CR in Italy, discussing its trengths and weaknesses as well as future perspectives.

From being centred on the acute phase, health care of cardiac patients is increasingly involving the long-term chronic phase. The aim of the present position paper is to provide the state of the art of CR in Italy, discussing strengths and weaknesses as well as future perspectives.

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.

Background: Chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD) are leading causes of morbidity and mortality worldwide. Through shared risk factors and pathophysiological mechanisms, CHF and COPD frequently coexist. The concurrent disease has important therapeutic implications and independently predicts worsened mortality, impaired functional status, and health service use. However, assessment of the comorbidity varies widely according to the population studied, diagnostic criteria and measurement tools applied. Both syndromes have been studied extensively but largely separately, mostly in the domain of the pulmonologist for COPD and in the domain of the cardiologist for CHF., Study Objectives and Design: The aim of the study is to evaluate in an Italian outpatients setting (10 cardiology and 10 pulmonology centers from the same institution) the prevalence, clinical profile and the routine diagnostic, functional and therapeutic work-up applied by cardiologists and pulmonologists in the presence/suspicion of concurrent disease in patients in a stable phase of their disease. For this purpose, CHF and COPU outpatients will be enrolled in a multicenter, nationwide, prospective observational study. Risk estimation of comorbidity will be based on suspected, documented or patient-reported diagnosis of COPD/CHF. In the absence of documented concurrent diagnosis, each specialist will describe the diagnostic, functional and therapeutic work-up applied., Conclusion: The design of the study focused on the diagnostic validation of the CHF-COPD comorbidity aims to provide relevant new information on the assessment of the coexistent condition in the cardiac and pulmonary outpatients setting and on specialty-related different diagnostic and therapeutic strategies of comorbidity utilized in real life clinical practice. The symptomatic and prognostic benefits resulting from a combined approach to CHF/COPD could outweigh those attainable by treating either condition alone.

Background: Using data from the Italian SurveY on carDiac rEhabilitation (ISYDE-2008), this study provides insight into the level of implementation of cardiac rehabilitation in patients with chronic heart failure (CHF)., Methods: Data from 165 Italian cardiac rehabilitation units were collected online from 28 January to 10 February 2008., Results: The study cohort consisted of 2281 patients (66.9 ± 11.8 years): 285 (71.3 ± 12.2 years, 66% male) CHF patients and 1996 (66.3 ± 11.6 years, 74% male) non-CHF patients. Compared with non-CHF, CHF patients were older, showed more comorbidity, had lower left ventricular (LV) ejection fraction and reduced access to functional evaluation, underwent more complications during cardiac rehabilitation, and had longer length of in-hospital stay. CHF patients were also more likely to be transferred to ICU (9 versus 3%, P < 0.0001), and less likely to be discharged home (85 versus 92%, respectively, P < 0.0001). Also, discharge prescriptions were significantly different from those of non-CHF patients. Finally, CHF patients had higher mortality during cardiac rehabilitation (1.7 versus 0.5%, P = 0.01). After adjusting for age, ejection fraction, comorbidity, previous interventions and complications during cardiac rehabilitation, multivariate logistic analysis showed that not performing any of the physical performance tests [odds ratio (OR) = 7.0, 95% confidence interval (CI), 1.9-25.8, P = 0.003], acute respiratory failure (OR = 2.3, 95% CI, 1.3-4.1, P = 0.002), acute kidney insufficiency or worsening of chronic kidney disease (OR = 2.9, 95% CI, 1.5-5.6, P = 0.001) and worsening of cognitive impairment (OR = 3.7, 95% CI, 2.0-6.7, P < 0.001) were significant predictors of death in CHF patients., Conclusion: The ISYDE-2008 survey provided a detailed snapshot of cardiac rehabilitation in CHF patients, and confirmed the complexity and the more severe clinical course of these patients during cardiac rehabilitation.

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, β-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., (Copyright © 2011 Elsevier Ireland Ltd.

The increasing evidence on the favourable cost/effectiveness impact of the comprehensive cardiac rehabilitation program for the treatment of a wide spectrum of cardiovascular conditions have imposed to healthcare services a major attention on a critical analysis of the results in different clinical indications and delivery organisations. The Regional Health Agency of Liguria, in the occasion of drawing up regional guidelines directed to define the clinical indications and the effectiveness of the cardiac rehabilitation delivery model (in-patients, out-patients and home-based) and its requisites, indications and procedures, has updated the reference guidelines (PLNG and SIGN) with the evidence provided by the more recent literature, focusing its attention on the clinical and, in particular, organizational effectiveness. The document, on the base of these evidences, provides some effective proposals and some organizational advices.

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.

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.

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.

Background: Cardiac rehabilitation programmes are a proven treatment for individuals with recent myocardial infarction, resulting in reduced morbidity and mortality compared to usual care. Unfortunately, following completion of a cardiac rehabilitation programme, risk factors and lifestyle behaviours may deteriorate. The GlObal Secondary Prevention strategiEs to Limit event recurrence after myocardial infarction (GOSPEL) study investigates the benefits of a programme of continued educational and behavioural interventions to achieve optimal long-term secondary prevention goals., Design: This will be a multicentre, randomized, controlled study carried out in 78 Italian cardiac rehabilitation centres., Methods: After completion of an initial cardiac rehabilitation programme, patients with recent (<3 months) myocardial infarction were randomized to either a long-lasting (over 3 years) multifactorial continued educational and behavioural programme (intensive approach) or usual care (control) group. Intensive approach patients participated in extensive cardiac rehabilitation sessions, monthly from months 1 to 6, then every 6 months for 3 years. Each session consisted of aerobic exercise, comprehensive lifestyle and risk factor counselling, and clinical assessment. Usual care patients returned to their family physicians' care, and attended the reference centre only for the 6-month and then annual scheduled assessment. The efficacy of the two different strategies will be evaluated in terms of morbidity and mortality as primary endpoint., Results: From January 2001 through December 2002, 3241 patients were enrolled. Results will be available in mid 2006., Conclusions: The GOSPEL trial, the rationale and design of which we present here, was designed to test a new strategy of secondary prevention delivery and to raise standards of long-term secondary prevention in Italy. With a cohort of over 3200 patients, GOSPEL is the largest randomized, multifactorial lifestyle and risk factor intervention trial after myocardial infarction conducted so far.

Background: Since the large multicenter DIG trial has shown no effects of digitalis on the all-cause mortality of patients with chronic heart failure (HF), the broad prescription of this drug in patients with HF appears to be at the very least, questionable. The aims of this study were: to analyze prescription patterns of digitalis, from 1995 to 2000, in a large group of outpatients with HF; to analyze the independent predictors of digitalis prescription and to evaluate the impact of the results of the DIG trial on the prescription rate of this drug., Methods: From 1995 to 2000, 11 070 HF outpatients (mean age 64 +/- 12 years, ejection fraction 35 +/- 12%) were enrolled in a large Italian database., Results: Out of 11 070 patients, 7198 (65%) were treated with digitalis. At multivariate analysis, the following variables were independently associated with digitalis prescription; atrial fibrillation (odds ratio [OR] 3.3, 95% confidence interval [CI] 2.9-3.8), ejection fraction < 30% (OR 1.7, 95% CI 1.5-1.9), NYHA class III-IV vs II-III (OR 1.3, 95% CI 1.2-1.5), admission for HF during the previous year (OR 1.4, 95% CI 1.2-1.5). After the publication of the DIG trial, there was a significant reduction in the rate of digitalis prescription: the percentage of patients taking digitalis fell from 68% in 1996-1997 to 61% in 1998-1999 (p < 0.001)., Conclusions: Over 60% of Italian outpatients with HF were treated with digitalis; as expected, patients with a low ejection fraction, atrial fibrillation and in a more advanced stage of HF are more likely to receive this drug. Finally, after the publication of the DIG trial, the rate of digitalis prescription significantly decreased.

Cardiac rehabilitation is accepted as an important component in the management of heart disease. Diabetes Mellitus is a chronic disease frequently associated to ischemic heart disease and both disease require continuing medical care, aggressive treatment of other risk factors, educational programs for self management of disease to prevent acute complication. The scientific community should offer standard of care for management of diabetic patients with coronary artery disease, and should design new strategies to promote prevention in this high risk patients. The need to define characteristics and peculiar problems of diabetics patients with ischemic heart disease encouraged the Board of the Italian Group of Cardiac Rehabilitation and Prevention (GICR) to set up a working group composed of cardiologists and diabetologists chosen on the basis of their proven specific experience. The document is subdivided in six parts. In the first section is described the cardiovascular risks in patients with diabetes and the importance of post-prandial hyperglycemia and glycemic variability. We analyse also the difference in prevalence of ischemic heart disease in Italian diabetic patients compared with other countries. In the second section we described clinical presentation of ischemic heart disease in diabetic patients such as acute myocardial infarction and unstable angina, and the revascularization procedures (balloon angioplasty and coronary bypass surgery). We analysed the differences between the procedures and the evidence-based results. In patients with myocardial infarction we analysed the evidence-based therapy and specific advantages of aspirin, beta-blockers and ace-inhibitor in diabetic patients. In this section we also posed particular attention to the clinical course of patients who underwent bypass grafting and to the impact of diabetes on short and long-term results and on main intervention-related complications including deep infections, mediastinitis, neurological problems, renal failure. In the third section we evaluated the factors responsible of atherosclerosis progression and their treatment, and we underlined that cardiac rehabilitation is less effective for patients with diabetes mellitus. Suggestions proposed in this paper about risk factors are in line with the recommendations of standards guidelines of American Diabetics Association. In patients with concomitant diabetes and ischemic heart disease we suggest blood pressure <130/80, LDL-cholesterol <100 mg/dl, triglycerides <150 mg/dl and daily physical activity. In the fourth section we analysed therapeutic regimens and management of diabetes. We posed particular attention on insulin therapy in acute phase of myocardial infarction and in recent coronary bypass grafting, and chronic use of oral antidiabetic drugs or insulin. In the fifth section we provided some recommendations on the organization of educational programs and physical activity in these patients. In the last section we provided some information on diagnosis of coronary artery disease in diabetes, aim of screening and in which patients is need to perform diagnostic tests. We described the available diagnostic tests with the differences in each method.

In 2001-2002 the Italian Working Group on Cardiac Rehabilitation (CR) developed the ISYDE project, a survey on CR in Italy. In 2001, the CR units were 144 (57% in the North of the country), 58% in general hospitals, 23% in private hospitals, 8% in rehabilitative hospital, and only 2% in university clinics. Patients admitted to CR were 60,819 (vs 37.049 in 1996, +64%); 86% of CR units treated > 100 pts/year (vs 66% in 1996; +32%). Patients were admitted to CR units after cardiosurgery in 55% of cases, after myocardial infarction in 22%, and for chronic heart failure in 9.6%, without significant differences respect to 1996. A special survey investigated the work-up performed in patients with recent myocardial infarction. The admission ranges from 11th to 20th day, the mean duration of the CR programs ranges from 21 to 34 days. Most of italian CR units have a definite program for risk stratification and secondary prevention. In particular, the programs of exercise training, educational interventions concerning diet, lifestyle, and smoking cessation, and psychological intervention are well designed, developed, and evaluated before discharge in most cases. In conclusion, although in recent years the number of CR units are increasing, and the quality of care may be well-established by serial evaluations scheduled before discharge and during the long-term follow-up, a further development is mandatory to face the needs of cardiac patients in the post-acute and chronic phase of a cardiac disease.

A well defined Italian sample from Trino Vercellese (Northern Italy) is analysed for 75 nuclear DNA RFLPs. It represents the only European sample [Matullo et al 1994] which is unmixed in a comparative study of eight populations from four continents [Bowcock et al 1991a; Lin et al 1994]. Genetic substructure of this sample has been investigated by allele sharing distances and no bias or higher homogeneity is shown. Genetic variability between populations was measured by the FST statistics (average FST was 0.138 +/- 0.086). Average heterozygosity for eight populations was 0.312 +/- 0.069. Genetic distances were evaluated between pairs of populations. Phylogenetic trees were reconstructed and principal component analysis performed. Particular attention has been given to the genetic relationship between our sample and the mixed-Caucasoid sample: 14 out of 75 markers show statistically significant frequency differences (P < 0.05), 5 of which are significant at a probability level < 1%: GH/Bg1II (Lower system), D7S1/HindIII, D17S71/MspI, EPB3/PstI, HLA-DQA. Hypotheses on admixed origin of Europeans has been discussed.

(1) The microgeographic structure of Sardinia, well documented from a historical and linguistic point of view, further supported by archaeological evidence, can also be dissected at the genetic level: gene frequencies show heterogeneities which are statistically significant. (2) Dendrogram analyses performed with different methods lead to the same result: even if gene frequencies cluster linguistically defined geographic domains in agreement with historical and archaeological evidence, no phylogenetic tree can be inferred, very likely because the assumptions which allow a phylogenetic tree to be a valid model of evolution (mainly constant evolutionary rates and independence between branches) do not apply to the genetic history of Sardinia. (3) Evidence of a qualitative association between distribution of genes and distribution of languages or dialects seems to emerge also at the microgeographic level of our analysis. More linguistic and genetic data are planned to be considered.

Trino Vercellese, a village of Piedmont (Italy), was selected with the aim at reconstructing the genetic history of a putative Celtic sample known to be settled in Italy with the name of Rigomagus since pre-roman times. The HLA-A, Cw, B, DR and DQ antigens of 101 unrelated individuals have been typed. The antigens characterizing this sample for their higher frequency are shown to be A3, A11, A32, B35, B39, Bw52, Cw4, DRw11, DRw13, DQw7. Gene frequencies are estimated by maximum likelihood and Hardy-Weinberg equilibrium was tested with no deviant genetic locus. Two-locus haplotype frequencies were also estimated and those with significant associations tabulated. "Extended" haplotypes were reconstructed: the three most frequent haplotypes (covering a total frequency of 11.5%) share the same Cw, B, DR and DQ alleles. Comparisons with other Italian and European samples are indicated to challenge archeological evidence of a pre-roman genetic stratification of the people living in our old Rigomagus.

We analysed a sample of 55 unrelated individuals from Trino Vercellese, a village in northern Italy. It represents the only European sample which is unmixed in a comparative study of eight populations from four continents [Bowcock et al 1991a; Lin et al 1994]. RFLP analysis was performed on 32 DNA markers, for a total of 37 independent alleles. Genetic variability between populations was measured by the FST statistics (average FST is 0.138). Average heterozygosity was calculated for each marker and for each population. Genetic distances were evaluated between pairs of populations. Phylogenetic trees were reconstructed and principal component analysis performed.

Human histocompatibility (HLA) gene frequencies were studied in the Italian population. A random sample of healthy individuals born in several Italian regions and provinces was studied to estimate HLA-A, -B, -C and -DR gene frequencies using the maximum likelihood method. The goodness of fit to Hardy-Weinberg proportions was evaluated by the likelihood ratio statistics. Different Italian regions and provinces show significant differences in the HLA alleles, providing further evidence for the genetic heterogeneity in the Italian population. This heterogeneity is also displayed by a synthetic geographical representation which uses colour to map the most informative gene differences. Statistically significant gametic associations between HLA-A, -B, -C and -DR loci are reported. The difference between northern and southern Italy and between continental Italy and Sardegna is clearly shown also by their heterogeneous linkage disequilibria.
