Predictors of survival in patients undergoing cardiac rehabilitation after transcatheter aortic valve replacement (TAVR): a multicenter retrospective study.

Background: The aim of this study was to evaluate cardiac rehabilitation (CR)-derived predictors of outcome in patients discharged from rehabilitation after transcatheter aortic valve replacement (TAVR).

Methods: We retrospectively analyzed data from 232 TAVR patients (aged 82±6 years, 55% females) discharged following an average 3-week residential CR program in the period January 2009 to December 2017. Comorbidities (cumulative illness rated state-comorbidity index, CIRS-CI), echocardiography on admission, disability (Barthel Index [BI]) and functional capacity (6-min walk distance, 6MWD) at discharge, and maximal training session intensity expressed in METs/min were collected.

Impact of in-hospital cardiac rehabilitation on mortality and readmissions in heart failure: A population study in Lombardy, Italy, from 2005 to 2012.

Aims: The 2016 European guidelines for the diagnosis and treatment of heart failure classified cardiac rehabilitation as a mandatory class I intervention. We aimed to analyse in heart failure patients the impact of an in-hospital cardiac rehabilitation programme on all-cause mortality and readmissions.

Methods: From the Lombardy healthcare administrative database, we analysed in patients with incident heart failure, from 2005 to 2012, the number of all hospitalisations, cardiac rehabilitation admissions, post-discharge deaths, outpatient drug prescriptions and visits.

[Consensus document and recommendations for the prevention of cardiovascular disease in Italy - 2018].

Cardiovascular prevention represents a cornerstone of modern strategies to reduce the burden of cardiovascular disease. It is of key importance to prevent cardiovascular diseases and associated events, not only to reduce morbidity and mortality, but also to increase the years of wellness in the aging population and to make the growing socio-economic burden imposed by cardiovascular events more sustainable.The current approach to prevention is based on an integrated use of effective lifestyle measures and, whenever appropriate, of antihypertensive and antidiabetic drugs, lipid-lowering agents and antiplatelet drugs.

[Heart rate as a therapeutic target after acute coronary syndrome and in chronic coronary heart disease].

For patients with stable coronary artery disease (SCAD), either after hospitalization for acute cardiac events or in the chronic phase, comprehensive treatment programs should be devoted to: (i) reducing mortality and major adverse cardiovascular events, (ii) reducing the ischemic burden and related symptoms, and (iii) increasing exercise capacity and quality of life.Heart rate (HR) has demonstrated to have prognostic value and patients beyond the limit of 70 bpm display increased risk of all the above adverse outcomes, even after adjustment for parameters such as the extension of myocardial infarction and the presence of heart failure. It is well known that a sustained HR elevation may contribute to the pathogenesis of SCAD, being the likelihood of developing ischemia, plaque instability, trigger for arrhythmias, increased vascular oxidative stress, and endothelial dysfunction the mechanisms resulting in this effect.

Shortened questionnaires to assess anxiety and depression during in-hospital rehabilitation: clinical validation and cutoff scores.

Background: A postacute phase needs reliable routine screening instruments in order to identify the patients to be referred for a clinical interview with a psychologist. The aim of this study was to estimate the clinical cutoff scores of the anxiety and depression questionnaires and their clinical validity using a gold standard.

Methods: The study involved 177 patients with pulmonary, cardiac, or neurological disease undergoing in-hospital rehabilitation.

Current activities of Cardiovascular Rehabilitation in the ambulatory setting of the Lombardy Region.

In the present work, the current activities of Cardiovascular Rehabilitation and Prevention (CRP) in the ambulatory setting of the Lombardy Region (Italy) are described. Based on the 2012 Legislation, ambulatory CRP is delivered by means of three programme categories (MAC 6, 7, and 8) with different degrees of intensity. The patient evaluation of global cardiovascular/clinical risk, comorbidity, and disability is the cornerstone for MAC prescription.

Prospective Use of Microvolt T-Wave Alternans Testing to Guide Primary Prevention Implantable Cardioverter Defibrillator Therapy.

Background: We hypothesized that a negative microvolt T-wave alternans (MTWA) test would identify patients unlikely to benefit from primary prevention implantable cardioverter defibrillator (ICD) therapy in a prospective cohort.

Methods and results: Data were pooled from 8 centers where MTWA testing was performed specifically for the purpose of guiding primary prevention ICD implantation. Cohorts were included if the ratio of ICDs implanted in patients who were MTWA "non-negative" to patients who were MTWA negative was >2:1, indicating that MTWA testing had a significant impact on the decision to implant an ICD.

[Nonsteroid anti-inflammatory drugs (NSAID) and risk of cardiovascular events. Literature review and clinical implications].

Non steroid anti-inflammatory drugs (NSAIDs) are largely used for treatment of acute and chronic pain, even for long periods of time (months or years). While it is known that their use is frequently associated with gastrointestinal damage, including major bleedings from peptic ulcer, the risk of cardiovascular events related to NSAID has received much less attention. However, there is a large body of evidence showing that NSAIDs (both "traditional", such as diclofenac or indobufen, and selective cyclooxygenase inhibitors, COX-2) are associated with a significant increase of risk of cardiovascular events, both fatal and nonfatal.

[Erectile dysfunction and cardiovascular disease: focus on].

Erectile dysfunction (ED) is a common clinical problem and its prevalence increases in frequency with age. ED is a risk marker for major cardiovascular events independently of other more common risk factors in men with and without known cardiovascular disease. On the basis of the "artery-size hypothesis" patients with cardiovascular disease often report ED before disease detection, in average 3 years.

A combined anatomic and electrophysiologic substrate based approach for sudden cardiac death risk stratification.

Background: Although left ventricular ejection fraction (LVEF) is the primary determinant for sudden cardiac death (SCD) risk stratification, in isolation, LVEF is a sub-optimal risk stratifier. We assessed whether a multi-marker strategy would provide more robust SCD risk stratification than LVEF alone.

Methods: We collected patient-level data (n = 3355) from 6 studies assessing the prognostic utility of microvolt T-wave alternans (MTWA) testing.

Clinical utility of N-terminal pro-B-type natriuretic peptide for risk stratification of patients with acute decompensated heart failure. Derivation and validation of the ADHF/NT-proBNP risk score.

Background: NT-proBNP has been associated with prognosis in acute decompensated heart failure (ADHF). Whether NT-proBNP provides additional prognostic information beyond that obtained from standard clinical variables is uncertain. We sought to assess whether N-terminal pro-B-type natriuretic peptide (NT-proBNP) determination improves risk reclassification of patients with ADHF and to develop and validate a point-based NT-proBNP risk score.

[Measuring change in rehabilitative cardiology: reliability of a short questionnaire to assess an outcome].

Unlabelled: The present Italian health planning demands the use of tools, care and treatments useful for the National Health Service, but with empirical effectiveness scientifically sustained. Aim of the present paper is to verify the validity, the reliability and the responsiveness of the factor "Perception of positive change" (named Schedule C) in cardiovascular rehabilitation.

Method: The reliability of the Schedule C of the CBA VE has been examined comparing the mean scores obtained from each item at the entry and just before the discharge through the t-Student for paired sample.

Clinical utility of microvolt T-wave alternans testing in identifying patients at high or low risk of sudden cardiac death.

Background: Previous studies have demonstrated that microvolt T-wave alternans (MTWA) testing is a robust predictor of ventricular tachyarrhythmias and sudden cardiac death (SCD) in at-risk patients. However, recent studies have suggested that MTWA testing is not as good a predictor of "appropriate" implantable cardioverter-defibrillator (ICD) therapy as it is a predictor of SCD in patients without ICDs.

Objective: To evaluate the utility of MTWA testing for SCD risk stratification in patients without ICDs.

[Prevention of sudden death in heart failure patients: cardiac resynchronization therapy with or without defibrillation back-up].

The prevalence and incidence of heart failure are progressively increasing in both Europe and the United States. Despite many advances in diagnosis and therapy, morbidity and mortality remain high and long-term prognosis is still poor in most heart failure patients. The use of implantable devices, cardiac resynchronization therapy and implantable cardioverter-defibrillators plays a pivotal role in the treatment of heart failure.

Preoperative n-3 polyunsatured fatty acids are associated with a decrease in the incidence of early atrial fibrillation following cardiac surgery.

Background: Atrial fibrillation (AF) after cardiac surgery is associated with increased mortality, morbidity, and expenditure. Controversial data exist on possible preventive effects of n-3 polyunsatured fatty acids (PUFAs) against postoperative AF. We investigated whether preoperative PUFA therapy is effective in reducing AF after cardiac surgery during the surgical hospitalization and/or the cardiac rehabilitation period.

Proportion of patients needing an implantable cardioverter defibrillator on the basis of current guidelines: impact on healthcare resources in Italy and the USA. Data from the ALPHA study registry.

Aims: Implantable cardioverter defibrillators (ICD) improve survival in selected patients with left ventricular dysfunction or heart failure (HF). The objective is to estimate the number of ICD candidates and to assess the potential impact on public health expenditure in Italy and the USA.

Methods And Results: Data from 3513 consecutive patients (ALPHA study registry) were screened.

[Risk stratification for sudden cardiac death: from the electrophysiological study to T-wave alternans].

T-wave alternans is a change, in the microvolt range, of T-wave amplitude on an ABABAB sequence. At present, various groups of patients have been evaluated, including those with myocardial infarction, congestive heart failure, implantable cardioverter-defibrillators and a clinical indication for programmed ventricular stimulation. In all clinical conditions analyzed, T-wave alternans analysis demonstrated a good diagnostic accuracy, suggesting a possible clinical use of the test in these settings.

Right ventricular pressure changes during induced ventricular tachycardias predict clinical symptoms of cerebral hypoperfusion: implications for a reduction of unnecessary, painful ICD shocks.

Background: ICD shocks occurring in conscious patients (as in the case of well-tolerated arrhythmias, electromagnetic interference, or oversensing) have a deleterious impact on the quality of life. We evaluated if a hemodynamic parameter, calculated from the right ventricular pressure (RVP) or systemic arterial pressure (AP) signals, could predict early clinical symptoms of cerebral hypoperfusion during induced ventricular tachycardias (VTs).

Methods And Results: We analyzed 42 tolerated (no symptoms) and 30 untolerated (syncope or severe symptoms within 30 seconds from the onset) VTs, induced during electrophysiological study.

Plasma B-type natriuretic peptide predicts atrial fibrillation during rehabilitation after cardiac surgery.

Background: B-type natriuretic peptide (BNP) levels are known to predict atrial fibrillation (AF) occurrence short-term after cardiac surgery, but no information is available on their predictive potential at a later time point. We evaluated whether BNP levels predict postcardiac surgery AF events occurring during rehabilitation program. AF impact on hospitalization length and rehabilitation program have also been evaluated.

Prognostic value of T-wave alternans in patients with heart failure due to nonischemic cardiomyopathy: results of the ALPHA Study.

Objectives: The aim of this study was to assess the prognostic value of T-wave alternans (TWA) in New York Heart Association (NYHA) functional class II/III patients with nonischemic cardiomyopathy and left ventricular ejection fraction (LVEF) < or =40%.

Background: There is a strong need to identify reliable risk stratifiers among heart failure candidates for implantable cardioverter-defibrillator (ICD) prophylaxis. T-wave alternans may identify low-risk subjects among post-myocardial infarction patients with depressed LVEF, but its predictive role in nonischemic cardiomyopathy is unclear.
