Prognostic Value and Relative Cutoffs of Triglycerides Predicting Cardiovascular Outcome in a Large Regional-Based Italian Database.

BACKGROUND: Despite longstanding epidemiologic data on the association between increased serum triglycerides and cardiovascular events, the exact level at which risk begins to rise is unclear. The Working Group on Uric Acid and Cardiovascular Risk of the Italian Society of Hypertension has conceived a protocol aimed at searching for the prognostic cutoff value of triglycerides in predicting cardiovascular events in a large regional-based Italian cohort. METHODS AND RESULTS: Among 14 189 subjects aged 18 to 95 years followed-up for 11.2 (5.3-13.2) years, the prognostic cutoff value of triglycerides, able to discriminate combined cardiovascular events, was identified by means of receiver operating characteristic curve. The conventional (150 mg/dL) and the prognostic cutoff values of triglycerides were used as independent predictors in separate multivariable Cox regression models adjusted for age, sex, body mass index, total and high-density lipoprotein cholesterol, serum uric acid, arterial hypertension, diabetes, chronic renal disease, smoking habit, and use of antihypertensive and lipid-lowering drugs. During 139 375 person-years of follow-up, 1601 participants experienced cardiovascular events. Receiver operating characteristic curve showed that 89 mg/dL (95% CI, 75.8-103.3, sensitivity 76.6, specificity 34.1, P<0.0001) was the prognostic cutoff value for cardiovascular events. Both cutoff values of triglycerides, the conventional and the newly identified, were accepted as multivariate predictors in separate Cox analyses, the hazard ratios being 1.211 (95% CI, 1.063-1.378, P=0.004) and 1.150 (95% CI, 1.021-1.295, P=0.02), respectively. CONCLUSIONS: Lower (89 mg/dL) than conventional (150 mg/dL) prognostic cutoff value of triglycerides for cardiovascular events does exist and is associated with increased cardiovascular risk in an Italian cohort.

Management of Patients Treated with Direct Oral Anticoagulants in Clinical Practice and Challenging Scenarios.

It is well established that direct oral anticoagulants (DOACs) are the cornerstone of anticoagulant strategy in atrial fibrillation (AF) and venous thromboembolism (VTE) and should be preferred over vitamin K antagonists (VKAs) since they are superior or non-inferior to VKAs in reducing thromboembolic risk and are associated with a lower risk of intracranial hemorrhage (IH). In addition, many factors, such as fewer pharmacokinetic interactions and less need for monitoring, contribute to the favor of this therapeutic strategy. Although DOACs represent a more suitable option, several issues should be considered in clinical practice, including drug-drug interactions (DDIs), switching to other antithrombotic therapies, preprocedural and postprocedural periods, and the use in patients with chronic renal and liver failure and in those with cancer. Furthermore, adherence to DOACs appears to remain suboptimal. This narrative review aims to provide a practical guide for DOAC prescription and address challenging scenarios.

Aortic stiffness plays a role in the discrepancy between mitral valve lesion severity and hemodynamic burden of secondary mitral regurgitation.

BACKGROUND: By the framework of proportionate/disproportionate secondary mitral regurgitation (sMR), disproportionate sMR is characterized by a low left ventricular stroke volume (SV) and an out of proportion regurgitant fraction (RF) for the same effective regurgitant orifice area (EROA). The degree of aortic stiffness is a determinant of the ventricular forward SV. We aim to analyze the importance of aortic stiffness in influencing the discrepancy between measures of mitral valve lesion severity (EROA) and sMR hemodynamic burden (regurgitant volume [RV] and RF). METHODS: We enrolled stable patients with heart failure with reduced ejection fraction (HFrEF) and at least mild sMR. Mitral EROA, RV, RF and aortic pulse wave velocity (PWV) were measured by echocardiography. We defined three groups based on the degree of actual RF deviation from RF estimated by the linear regression equation of RF on EROA (concordant, low-discordant [residuals lower-than -5%] and high-discordant RF [residuals higher-than 5%]). RESULTS: 117 patients were analyzed (68±13 years; female 30%; LVEF 33±8%; EROA 16±12mm2; RV 24±15 ml; RF 27±13%; PWV 6.6 ± 3.2 m/s). LVEF, end-diastolic-volume and EROA didn't differ among groups. PWV and RV were higher in patients with high-discordant RF (p ≤ 0.01), whereas total left ventricular-SV and left ventricular outflow tract-SV (LVOT-SV) were lower (p ≤ 0.0004). PWV was associated with LVOT-SV (r=-0.3;p = 0.0008) and RV (r = 0.3;p = 0.0009). High-discordant RF was predicted by PWV (p = 0.001) independently of LVOT-SV and RV. CONCLUSION: In this HFrEF cohort with sMR, higher PWV was associated with higher-than-expected RF for a given EROA. Aortic stiffness might play a role in the discrepancy between mitral valve lesion severity and sMR hemodynamic burden.

Hypertriglyceridemia is associated with decline of estimated glomerular filtration rate and risk of end-stage kidney disease in a real-word Italian cohort: Evidence from the TG-RENAL Study.

BACKGROUND: This analysis investigated the role of hypertriglyceridemia on renal function decline and development of end-stage kidney disease (ESKD) in a real-world clinical setting. METHODS: A retrospective analysis using administrative databases of 3 Italian Local Health Units was performed searching patients with at least one plasma triglyceride (TG) measurement between 2013 and June 2020, followed-up until June 2021. Outcome measures included reduction in estimated glomerular filtration rate (eGFR) ≥30% from baseline and ESKD onset. Subjects with normal (normal-TG), high (HTG) and very high TG levels (vHTG) (respectively <150 mg/dL, 150-500 mg/dL and >500 mg/dL) were comparatively evaluated. RESULTS: Overall 45,000 subjects (39,935 normal-TGs, 5,029 HTG and 36 vHTG) with baseline eGFR of 96.0 ± 66.4 mL/min were considered. The incidence of eGFR reduction was 27.1 and 31.1 and 35.1 per 1000 person-years, in normal-TG, HTG and vHTG subjects, respectively (P<0.01). The incidence of ESKD was 0.7 and 0.9 per 1000 person-years, in normal-TG and HTG/vHTG subjects, respectively (P<0.01). Univariate and multivariate analyses revealed that HTG subjects had a risk of eGFR reduction or ESKD occurrence (composite endpoint) increased by 48% compared to normal-TG subjects (adjusted OR:1.485, 95%CI 1.300-1.696; P<0.001). Moreover, each 50 mg/dL increase in TG levels resulted in significantly greater risk of eGFR reduction (OR:1.062, 95%CI 1.039-1.086 P<0.001) and ESKD (OR:1.174, 95%CI 1.070-1.289, P = 0.001). CONCLUSIONS: This real-word analysis in a large cohort of individuals with low-to-moderate cardiovascular risk suggests that moderate-to-severe elevation of plasma TG levels is associated with a significantly increased risk of long-term kidney function deterioration.

Impact of eGFR rate on 1-year all-cause mortality in patients with stable coronary artery disease.

BACKGROUND: Coronary artery disease (CAD) is a leading cause of mortality and is often complicated by chronic kidney disease. We sought to investigate the prevalence of different degree of estimated glomerular filtration rate (eGFR) reduction, the clinical and bio-humoral correlates, its relationship with therapeutic management, and its predictive role on 1-year all-cause mortality, in patients with stable CAD. METHODS: We studied 4,130 patients with stable CAD recruited in a prospective, observational, nationwide study (START, STable coronary Artery diseases RegisTry) in Italy. Baseline clinical characteristics, pharmacological treatment, and all-cause 1-year mortality were evaluated according to groups of eGFR (<30; 30-59; 60-89; ≥90 ml/min/1.73 m2) at baseline. RESULTS: The presence and the degree of chronic kidney disease entailed an unfavorable risk profile, since it was gradually associated with more comorbidities. Furthermore, progressively lower eGFR values were associated to lower diastolic blood pressure and hemoglobin values. As eGFR lowers, optimal medical treatment and its persistence overtime is reduced. Multivariate analysis showed that progressively lower eGFR significantly correlated with all-cause 1-year mortality [hazard ratio (HR): 1.02; 95% confidence intervals (CI): 1.01-1-03; p = 0.0001]. CONCLUSIONS: Low eGFR is associated with an increasing risk of all-cause mortality in patients with stable CAD. Chronic kidney disease may hamper the optimization of treatment limiting the use of drugs which may favorably impact cardiovascular and renal outcomes.

Left atrial strain predicts exercise capacity in heart failure independently of left ventricular ejection fraction.

AIMS: We hypothesized that left atrial (LA) remodelling and function are associated with poor exercise capacity as prognostic marker in chronic heart failure (CHF) across a broad range of left ventricular ejection fraction (LVEF). METHODS AND RESULTS: One hundred seventy-one patients with CHF were analysed [age 65 ± 11 years, 136 males (80%); 86 heart failure with reduced ejection fraction (HFrEF), 27 heart failure with mid-range ejection fraction (HFmrEF), 58 heart failure with preserved ejection fraction (HFpEF)]. All patients underwent echocardiography and maximal cardiopulmonary exercise testing and were classified according to a prognostic cut-off of peak VO2 (pVO2 ; 14 mL/kg/min). Seventy-seven (45%) patients reached pVO2  < 14 and 94 (55%) pVO2  ≥ 14 mL/kg/min. Between the two groups, there was a considerable difference in both left atrial volume (LAVi, 53 ± 24 vs. 44 ± 18 mL/m2 , P = 0.005) and function (LA reservoir strain 12 ± 5 vs. 20 ± 10%, P < 0.0001). Receiver-operating characteristic curves identified LA reservoir strain (area under the curve: 0.73 [0.65-0.80], P < 0.0001) as strong predictor for impaired pVO2 among all echocardiographic variables; LA reservoir strain < 23% had 37% specificity but a very high sensitivity (96%) in identifying a severely reduced pVO2 . In logistic regression analysis, LA reservoir strain < 23% was associated with a highly increased risk of pVO2  < 14 mL/kg/min (odds ratio 16.0 [4.7-54.6]; P < 0.0001). The multivariate analysis showed that a reduced LA reservoir strain was associated with pVO2  < 14 mL/kg/min after adjustment for age, body mass index (BMI), and clinical variables, that is, New York Heart Association class, atrial fibrillation, haemoglobin, and creatinine (b 0.22 [95% confidence interval, CI, 0.12-0.31]; P < 0.0001), and after adjustment for echocardiographic variables, that is, LVEF or left ventricular global longitudinal strain (LVGLS) and tricuspid annular plane systolic excursion (TAPSE) (b 0.16 [95% CI 0.08-0.24]; P < 0.0001). Patients with HFrEF, HFmrEF, and HFpEF were separately analysed. Among LA reservoir strain, LAVi, LVEF, LVGLS, and TAPSE, LA reservoir strain was the only one significantly associated with pVO2 in all subgroups (after adjustment for sex and BMI, P = 0.003, 0.04, and 0.01, respectively). CONCLUSIONS: In patients with CHF, an impaired LA reservoir function is independently associated with a severely reduced pVO2 . LA dysfunction represents a marker of poor prognosis across LVEF borders in the CHF population.

Is physical activity always good for you? The physical activity paradox.

Regular physical activity is a known protective factor for the prevention of non-communicable diseases such as cardiovascular disease, type 2 diabetes, breast, and colon cancer. Physical activity also has benefits for mental health, delays the onset of dementia, contributes to the maintenance of an adequate body weight and to general well-being. Research on physical activity has mainly focused on leisure and total time, and less on the activity in the workplace. The current guidelines actually recommend physical activity in any form and do not distinguish between the different areas, e.g. physical activity carried out during leisure time, at home or at work. However, new evidence suggests a contrast between the health effects of physical activity in leisure time vs. that in the workplace. In particular, while physical activity, even of high intensity in leisure time, has been associated with positive health outcomes, adverse consequences have been documented for physical activity in the workplace, both in terms of cardiovascular diseases, work absences due to illness and mortality from all causes. These contrasting effects of physical activity in leisure time compared to that in the workplace constitute the so-called 'physical activity paradox'.

Prevention after acute coronary syndrome the 'less is more' philosophy.

In the cardiology field, in recent years, we have witnessed an exponential increase in the use of both invasive and non-invasive instrument diagnostics. Particularly after an acute coronary syndrome, instrumental examinations, especially non-invasive ones, are often prescribed inappropriately until they almost completely replace the clinical evaluation. Their correct use, on the contrary, would require the choice of a test to be prescribed according to the epidemiological and clinical context of the individual patient. The strategy of early diagnosis, obtainable through instrumental screening and borrowed from oncological pathologies, was transferred 'tout court' in the cardiovascular field without any scientific basis, replacing the pharmacological or non-pharmacological intervention, such as the appropriate lifestyle, aimed at reducing cardiovascular risk factors. The guidelines of the main scientific societies define the most appropriate paths in the management of the coronary heart disease patients, both in the immediate post-acute phase and in the chronic phase. Although the guidelines sometimes show an excessive simplification of clinical problems, in an age in which the control of health expenditure has become a priority the correctness of the indications is an indispensable objective, being incontrovertible that a test is indicated only when an instrumental examination is able to modify the diagnostic-therapeutic path and the outcome of the patient.

Referral from vascular surgery to cardiovascular rehabilitation and related outcomes in patients with peripheral arterial disease: the THINKPAD-RELOADED survey.

The utilization of cardiovascular rehabilitation (CR) programmes in patients with Lower Extremity Peripheral Artery Disease (LEPAD) is generally poor, with limited evidence of current policies for referral. The aim of the study was to evaluate, within a cohesive network of CR and vascular surgery facilities with facilitated referral process, the clinical characteristic of LEPAD patients referred to CR and related outcomes, as compared to patients not referred. The present is an observational prospective study of consecutive patients recruited at vascular surgery facilities. Out of 329 patients observed, the average referral rate to CR was 34% (28% and 39% in patients with and without recent peripheral revascularization, p<0.05). LEPAD patients entering the CR programme were similar to those who did not according to sex, age, the vascular surgery setting of evaluation, and localization of arterial lesions. Patients with moderate intermittent claudication and patients with acute limb ischemia as index event were more represented among those who attended CR (41% vs 21% and 9% vs 2% respectively, p<0.05). Patients referred to CR had five times more episodes of acute coronary syndrome and heart failure as complication of the index event. The cardiovascular risk profile (obesity 29.5% vs 11%, p<0.05; hypercholesterolemia 80% vs 61%, p<0.05) was much worse in LEPAD patients referred to CR, but conversely, they better achieved secondary prevention targets, particularly for blood pressure control (97% vs 57%, p<0.05). All-cause 2-year mortality in the whole patients' population was 6%. Patients entering the CR programme displayed less events (13.5% vs 37.7%, p<0.05), mainly death (3.1% vs 11.3%, p<0.05) and limb-related events (4.2% vs 15.2%, p<0.05). The results of our study suggest that when a cohesive network of vascular surgery and CR facilities becomes available, the referral rate to rehabilitation may increase up to one third of eligible patients. Patients with higher comorbidity and cardiovascular risk seem to have priority in the referral process, nevertheless those with peripheral revascularization are still underestimated. Entering CR may ensure better cardiovascular risk profile and cardiovascular prognosis in LEPAD patients, and consequently the systematic adoption of this care model needs to be strongly recommended and facilitated.

Current management and treatment of patients with stable coronary artery diseases presenting to cardiologists in different clinical contexts: A prospective, observational, nationwide study.

Background Stable coronary artery disease (CAD) is a leading cause of mortality worldwide. Few studies document the complete sequence of investigation of the overall stable CAD population during outpatient visits or hospitalisation. Aim To obtain accurate and up-to-date information on current management of patients with stable CAD. Methods START (STable coronary Artery diseases RegisTry) was a prospective, observational, nationwide study aimed at evaluating the presentation, management, treatment and quality of life of stable CAD patients presenting to cardiologists during outpatient visits or discharged from cardiology wards. Results Over a 3-month period, 5070 consecutive patients were enrolled in 183 participating centres: 72% managed by a cardiologist during outpatient or day hospital visits and 28% discharged from cardiology wards. The vast majority of patients (87%) received a coronary angiography (86% of patients managed during outpatient visits and 90% during hospitalisation; p < 0.0001). Outpatients more frequently received optimal medical therapy (OMT; i.e. aspirin or thienopyridine, ß-blockers and statins) compared to hospitalised patients (70.2% vs 67.1%; p = 0.03). A personalised diet was prescribed in 58% (60.5% in outpatients and 52.9% in those admitted to hospitals; p < 0.0001), physical activity programmes were suggested in 65% (69.4% and 54.3%; p < 0.0001) and smoking cessation was recommended in 71% of currently smoking patients (73.2% and 65.2%; p = 0.02). Conclusions In this large, contemporary registry, patients with stable CAD discharged from cardiology wards more commonly underwent diagnostic imaging procedures and less frequently received OMT or lifestyle modification programmes compared to patients manged by cardiologists during outpatient visits.

ANMCO/GICR-IACPR/SICI-GISE Consensus Document: the clinical management of chronic ischaemic cardiomyopathy.

Stable coronary artery disease (CAD) is a clinical entity of great epidemiological importance. It is becoming increasingly common due to the longer life expectancy, being strictly related to age and to advances in diagnostic techniques and pharmacological and non-pharmacological interventions. Stable CAD encompasses a variety of clinical and anatomic presentations, making the identification of its clinical and anatomical features challenging. Therapeutic interventions should be defined on an individual basis according to the patient's risk profile. To this aim, management flow charts have been reviewed based on sustainability and appropriateness derived from recent evidence. Special emphasis has been placed on non-pharmacological interventions, stressing the importance of lifestyle changes, including smoking cessation, regular physical activity, and diet. Adherence to therapy as an emerging risk factor is also discussed.

Association Between Diabetes and 1-Year Adverse Clinical Outcomes in a Multinational Cohort of Ambulatory Patients With Chronic Heart Failure: Results From the ESC-HFA Heart Failure Long-Term Registry.

OBJECTIVE: Diabetes mellitus is associated with an increased risk of cardiovascular disease (CVD) and death. Because the prevalence of diabetes is rising worldwide and chronic heart failure (CHF) is becoming increasingly common with the aging population, it is timely to examine the impact of diabetes per se on 1-year adverse outcomes in patients with CHF. RESEARCH DESIGN AND METHODS: We prospectively assessed whether diabetes status independently affected the 1-year risk of all-cause and CVD mortality and first hospitalization for worsening heart failure (HF) in a multinational cohort of 9,428 outpatients with CHF enrolled in the European Society of Cardiology and Heart Failure Association Long-Term Registry. RESULTS: Compared with those patients without diabetes, patients with diabetes (n = 3,440, 36.5%) had higher cumulative rates of 1-year all-cause death (9.4% vs. 7.2%; adjusted hazard ratio [HR] 1.28; 95% CI 1.07-1.54), CVD death (4.8% vs. 3.8%; adjusted HR 1.28; 95% CI 0.99-1.66), and HF hospitalization (13.8% vs. 9.3%; adjusted HR 1.37; 95% CI 1.17-1.60), all independent of age, sex, BMI, smoking, systolic blood pressure, estimated glomerular filtration rate, hemoglobin, HF etiology, left ventricular ejection fraction, hypertension, statin use, and prior stroke or chronic obstructive pulmonary disease. Among CHF patients with HbA1c measurements available at baseline (n = 2,567), there was a significant and independent association between increasing HbA1c levels and the risk of 1-year survival outcomes. CONCLUSIONS: The presence of diabetes markedly increases the risk of 1-year adverse clinical outcomes in outpatients with CHF independent of multiple common risk factors. More effective and personalized treatment for diabetes should be considered in this particularly high-risk patient population.

[Physical activity and cardiovascular health]. / Attività fisica (moderata) e benessere cardiovascolare. Chi si ferma è perduto!

It is well known that regular moderate physical activity, in the context of a healthy lifestyle, significantly reduces the likelihood of cardiovascular events, both in primary and secondary prevention. In addition, it is scientifically proven that exercise can reduce the incidence of diabetes, osteoporosis, depression, breast cancer and colon cancer. Despite this strong evidence, sedentary lifestyle remains a widespread habit in the western world. Even in Italy the adult population has a poor attitude to regular physical activity. It is therefore necessary, as continuously recommended by the World Health Organization, to motivate people to "move" since the transition from inactivity to regular light to moderate physical activity has a huge impact on health, resulting in significant savings of resources. We do not need to be athletes to exercise - it should be part of all our daily routines.

A retrospective multicenter study on long-term prevalence of chronic pain after cardiac surgery.

BACKGROUND: There are limited data on sternotomy as a cause of chronic postsurgical pain, mainly restricted to 1 year after surgery. AIMS: To assess the prevalence of chronic post-sternotomy pain and its interference on daily living. METHODS: In three groups of patients, a standardized telephone interview was obtained at 3 months (n = 313), 1 year (n = 313), and 3 years (n = 319) following the rehabilitation program after cardiac surgery, in 11 rehabilitation centers. Presence, site, and the severity and interference of pain on selected daily living items were assessed. RESULTS: The prevalence of pain after cardiac surgery was 35.3% in the 3-month group, 26.8% in the 1-year group, and 19.8% in the 3-year group (P < 0.0001). Pain in the 3-year group was rated as moderate to severe in one-third of the patients. In patients aged above 75 years, the prevalence of pain in the 3-month and the 3-year group was nonsignificantly different [34.2 and 29.3%, respectively (NS)]. In the 3-month group, pain was more frequent in the female (51.4%) than in the male patients (31.3%; P < 0.01); in the remaining groups, a comparable prevalence was documented. CONCLUSION: Results form this large, retrospective, multicenter survey indicated that one out of five patients still complain pain at 3 years after cardiac surgery; persistence of pain was more common in the older patients. The approach to management of chronic pain by cardiologists and cardiac surgeons should be improved.

[Italian cardiologists and tobacco smoking. A survey on the prevalence and knowledge of smoking and strategies for smoking cessation in a cohort of Italian cardiologists]. / Cardiologi italiani e fumo di tabacco. Survey su prevalenza e conoscenza del tabagismo e delle strategie antifumo di una coorte di cardiologi italiani.

BACKGROUND: Tobacco use is the single most preventable cause of death. Its cessation is the most cost-effective strategy for reducing long-term cardiovascular morbidity and mortality. Although both healthcare professionals and the general population are aware of the detrimental effects of smoking on health, more than 25% of Italians are current smokers. Recent surveys showed that almost 50% of smoker patients relapse to smoke after having been discharged for acute coronary syndrome. Physicians who smoke may be a barrier for effective cessation interventions. Thus, it is important to assess cardiologists' attitude toward smoking habits and the implementation of smoking cessation programs. METHODS: The survey "Italian cardiologists and smoking habits" has been held in 2013 during the 44° National Congress of the Italian Association of Hospital Cardiologists (ANMCO) to assess cardiologists' smoking status, their level of knowledge about smoking cessation interventions and their involvement in the management of smoking cessation. Out of more than 1200 cardiologists attending the ANMCO congress, 610 subjects (aged 51 ± 11 years) answered an anonymous 35-item questionnaire; they were asked to declare their smoking status (9.5% current smokers). RESULTS: Among doctors who attended the survey, 58% correctly indicated smoking as an addiction and 45% regularly advised their patients to stop smoking. The majority of cardiologists (93%) reported a positive attitude toward smoking cessation strategies, 62% of them thought that cardiologists themselves should treat smoking dependence, though specific tools (70%) and education for the management of smoking cessation are lacking (66%). Two thirds of the entire sample of ANMCO cardiologists declared their willingness to participate in specialized educational programs. CONCLUSIONS: More than a half of Italian cardiologists are aware that smoking is an addiction. Although they feel themselves yet inadequate toward this approach, they are favorable to implement their own knowledge and skills toward smoking cessation.

Italian Survey on Prevalence and Disease Management of Chronic Heart Failure and Chronic Obstructive Pulmonary Disease comorbidity in ambulatory patients. SUSPIRIUM study rationale and design.

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.

[Appropriateness of diagnostic tests in cardiovascular prevention: what can we skip?]. / Appropriatezza delle procedure diagnostiche in prevenzione cardiovascolare: di che cosa possiamo fare a meno?

In recent years, a huge increase in the use of cardiac procedures, both invasive and non-invasive, was observed. Diagnostic tests, mainly non-invasive tests, are often prescribed inappropriately, in most cases replacing the clinical evaluation. The rate of inappropriate tests in cardiology is largely variable, depending on regional issues and different medical approach. When the test entails radiation exposure, the biological risk for both the patient and the environment must be taken into account. For this reason, the test that results in less biological risk should always be preferred as a first step.Moreover, it has not been clearly demonstrated that some diagnostic tests help to improve the outcome, that is to prevent cardiovascular events. As many as one sixth of the patients who undergo stress imaging are not taking proper medication, and very frequently no change in therapy is made after the test, regardless of the outcome. Since the appropriateness of diagnostic evaluation requests is mandatory, we focused on the diagnostic tests usually performed in primary and secondary prevention that carry no contribution to the clinical management of patients. This review addresses the need to optimize available resources, reduce costs and avoid unnecessary cardiovascular assessments, thereby enhancing the more efficient care delivery models.

Lower extremities peripheral arterial disease among patients admitted to cardiac rehabilitation: the THINKPAD registry.

BACKGROUND/OBJECTIVES: Lower extremities peripheral arterial disease (LE-PAD) across the wide range of conditions for Cardiac Rehabilitation (CR) is poorly understood. The "ATHerosclerosis of the lower extremIties as a liNKed comorbidity in Patients Admitted for carDiac rehabilitation" (THINKPAD) registry explored LE-PAD in CR patients in terms of prevalence and interventions delivered. METHODS: Multicenter, consecutive case series of 1506 patients discharged from 16 CR Units in Italy from May 1 to June 30, 2012. RESULTS: LE-PAD constituted a primary indication for CR and a comorbidity on admission in 2.6% and 9.3% of patients respectively. LE-PAD patients were significantly older (72 ± 9 vs. 67 ± 12 years, p<0.001) and displayed a worse cardiovascular risk profile (diabetes 38% vs. 23%, hypertension 86% vs. 63%, hypercholesterolemia 74% vs. 52%, smoking 72% vs. 50%, low level of physical activity 84% vs. 69%, impaired diet habits 69% vs. 55%, p<0.01 for all). COPD (17% vs. 11%, p<0.05), CKD (20% vs. 10%, p<0.01), and past history of coronary revascularization (29% vs. 14%, p<0.001) were also more represented in the LE-PAD group. Half of LE-PAD patients received a formal staging, with low provision of ABI (18%) and color Doppler (48%) investigation. Secondary prevention targets at the end of CR for blood pressure and lipid control were accomplished in 83% and 46% of patients respectively (strongly correlated with the presence of CAD), while other guideline-recommended drugs for LE-PAD were prescribed in less than 4% of cases. CONCLUSION: LE-PAD represents an uncommon referral indication for CR. Our data confirm its systematic underassessment and undertreatment.
