Relationship between skin autofluorescence levels and clinical events in patients with heart failure undergoing cardiac rehabilitation.

BACKGROUND: Advanced glycation end-products, indicated by skin autofluorescence (SAF) levels, could be prognostic predictors of all-cause and cardiovascular mortality in patients with diabetes mellitus (DM) and renal disease. However, the clinical usefulness of SAF levels in patients with heart failure (HF) who underwent cardiac rehabilitation (CR) remains unclear. This study aimed to investigate the associations between SAF and MACE risk in patients with HF who underwent CR. METHODS: This study enrolled 204 consecutive patients with HF who had undergone CR at our university hospital between November 2015 and October 2017. Clinical characteristics and anthropometric data were collected at the beginning of CR. SAF levels were noninvasively measured with an autofluorescence reader. Major adverse cardiovascular event (MACE) was a composite of all-cause mortality and unplanned hospitalization for HF. Follow-up data concerning primary endpoints were collected until November 2017. RESULTS: Patients' mean age was 68.1 years, and 61% were male. Patients were divided into two groups according to the median SAF levels (High and Low SAF groups). Patients in the High SAF group were significantly older, had a higher prevalence of chronic kidney disease, and more frequently had history of coronary artery bypass surgery; however, there were no significant between-group differences in sex, prevalence of DM, left ventricular ejection fraction, and physical function. During a mean follow-up period of 590 days, 18 patients had all-cause mortality and 36 were hospitalized for HF. Kaplan-Meier analysis showed that patients in the high SAF group had a higher incidence of MACE (log-rank P < 0.05). After adjusting for confounding factors, Cox regression multivariate analysis revealed that SAF levels were independently associated with the incidence of MACE (odds ratio, 1.86; 95% confidence interval, 1.08-3.12; P = 0.03). CONCLUSION: SAF levels were significantly associated with the incidence of MACE in patients with HF and may be useful for risk stratification in patients with HF who underwent CR.

Exercise-Based Cardiac Rehabilitation and All-Cause Mortality Among Patients With Atrial Fibrillation.

Background There is limited evidence of long-term impact of exercise-based cardiac rehabilitation (CR) on clinical end points for patients with atrial fibrillation (AF). We therefore compared 18-month all-cause mortality, hospitalization, stroke, and heart failure in patients with AF and an electronic medical record of exercise-based CR to matched controls. Methods and Results This retrospective cohort study included patient data obtained on February 3, 2021 from a global federated health research network. Patients with AF undergoing exercise-based CR were propensity-score matched to patients with AF without exercise-based CR by age, sex, race, comorbidities, cardiovascular procedures, and cardiovascular medication. We ascertained 18-month incidence of all-cause mortality, hospitalization, stroke, and heart failure. Of 1 366 422 patients with AF, 11 947 patients had an electronic medical record of exercise-based CR within 6-months of incident AF who were propensity-score matched with 11 947 patients with AF without CR. Exercise-based CR was associated with 68% lower odds of all-cause mortality (odds ratio, 0.32; 95% CI, 0.29-0.35), 44% lower odds of rehospitalization (0.56; 95% CI, 0.53-0.59), and 16% lower odds of incident stroke (0.84; 95% CI, 0.72-0.99) compared with propensity-score matched controls. No significant associations were shown for incident heart failure (0.93; 95% CI, 0.84-1.04). The beneficial association of exercise-based CR on all-cause mortality was independent of sex, older age, comorbidities, and AF subtype. Conclusions Exercise-based CR among patients with incident AF was associated with lower odds of all-cause mortality, rehospitalization, and incident stroke at 18-month follow-up, supporting the provision of exercise-based CR for patients with AF.

Patients with Heart Failure During and After Inpatient Cardiac Rehabilitation.

BACKGROUND: Heart failure is the third most fatal disease in Germany and generates considerable treatment costs. The multimodal program of inpatient rehabilitation can improve the symptoms and prognosis of these patients. At the present time, however, only few data are available on the effectiveness of rehabilitation for heart failure patients. METHODS: After receiving study approval from the ethics committee of the Saxony-Anhalt Medical Association, 200 patients with a primary or secondary diagnosis of heart failure were prospectively included in the study at Paracelsus-Harz-Clinic Bad Suderode, Quedlinburg, Germany. Baseline parameters such as age, gender, and BMI were documented. Outcome variables included NYHA classifications, quality of life, and mortality. For follow-up, the patients were contacted again by mail or phone after three and 12 months and, data on symptoms and serious events were recorded. RESULTS: The proportion of patients with a highly reduced ejection fraction (HFrEF) was 13.5%, with a midrange reduced ejection fraction (HFmrEF) 33%, and with preserved ejection fraction (HFpEF) 53.5%. The mean age was 64 ± 11.9 years, the proportion of women 24.1%. The effects of rehabilitation were documented by low overall mortality (no patient died during the stay, only 4% of the patients died in the 12-month follow-up) and an improvement in NYHA classification during and after the inpatient rehabilitation. CONCLUSION: This monocentric study showed effects both for symptoms (improvement in NYHA classifications) and prognosis (overall mortality) after rehabilitation. These data reflect the effectiveness of multimodal rehabilitation and underscore the need for rehabilitation in patients diagnosed with heart failure after an acute event and hospital stay or who present with chronic deterioration.

Inpatient Cardiac Rehabilitation of LVAD Patients-Updated Recommendations from the Working Group of the German Society for Prevention and Rehabilitation of Cardiovascular Diseases.

Cardiac rehabilitation physicians are faced to an increasing number of heart failure patients supported by left ventricular assist devices (LVAD). Many of these patients have complex medical issues and prolonged hospitalizations and therefore need special cardiac rehabilitation strategies including psychological, social, and educational support which are actually poorly implemented.Cardiac rehabilitation with clear guidance and more evidence should be considered as an essential component of the patient care plan especially regarding the increasing number of destination patients and their long-term follow-up.In this article the working group for postimplant treatment and rehabilitation of LVAD patients of the German Society for Prevention and Rehabilitation of Cardiovascular Diseases has summarized and updated the recommendations for the cardiac rehabilitation of LVAD patients considering the latest literature.

Factors related to the discontinuation and mortality rates of a cardiac rehabilitation programme in patients with Chagas disease: a 6-year experience in a Brazilian tertiary centre.

OBJECTIVES: To describe the clinical and sociodemographic characteristics of participants as well as discontinuation and mortality rates in a cardiac rehabilitation programme (CRP) tailored to Chagas disease (CD). METHODS: Participants underwent functional capacity, anthropometry and cardiac function evaluations before beginning a CRP. Univariate and multivariate Cox proportional hazards models were performed to investigate the associations between clinical and sociodemographic characteristics at baseline with discontinuation rates and deaths. RESULTS: Forty-two patients were enrolled in the CRP (61.9% men, mean age of 58.1 ± 11.8 years). During a median follow-up period of 10.8 months, 74% discontinued and 14% died while enrolled in CRP. 34% of the patients who discontinued CRP died during follow-up. White race (HR = 0.09; 95% CI 0.01-1.00), right ventricular systolic dysfunction (HR = 10.54; 95% CI 1.24-89.50) and oxygen pulse (HR = 0.69; 95% CI 0.48-0.99) were independently associated with death while enrolled in CRP. Married status (HR = 0.44; 95% CI 0.21-0.95) was independently associated with discontinuation rates from CRP. VO2 peak (HR = 0.85; 95% CI 0.74-0.98) and CRP discontinuation due to CD-related reasons (HR = 8.33; 95% CI 1.91-36.27) were the variables independently associated with death after discontinuation of CRP. CONCLUSION: In this population, sociodemographic aspects and severity of CD were important determinants of CRP discontinuation and mortality.

OBJECTIFS: Décrire les caractéristiques cliniques et sociodémographiques des participants ainsi que les taux d'abandon et de décès dans un programme de réadaptation cardiaque (PRC) adapté à la maladie de Chagas (MC). MÉTHODES: Les participants ont subi des évaluations de la capacité fonctionnelle, de l'anthropométrie et de la fonction cardiaque avant de commencer un PRC. Des modèles de risques proportionnels de Cox univariés et multivariés ont été appliqués pour étudier les associations entre les caractéristiques cliniques et sociodémographiques au départ avec les taux d'abandon et les décès. RÉSULTATS: 42 patients ont été enrôlés dans le PRC (61,9% d'hommes, âge moyen de 58,1 ± 11,8 ans). Au cours d'une période médiane de suivi de 10,8 mois, 74% ont abandonné et 14% sont décédés durant leur enrôlement au PRC. 34% des patients qui ont arrêté le PRC sont décédés au cours du suivi. La race blanche (HR = 0,09; IC95%: 0,01-1,00), le dysfonctionnement systolique ventriculaire droite (HR = 10,54; IC95%: 1,24-89,50) et le pouls d'oxygène (HR = 0,69; IC95%: 0,48-0,99) étaient indépendamment associés avec le décès lors de l'enrôlement au PRC. Le statut marié (HR = 0,44; IC95%: 0,21-0,95) était indépendamment associé aux taux d'abandon de la CRP. Le pic de VO2 (HR = 0,85; IC95%: 0,74-0,98) et l'arrêt du PRC pour des raisons liées à la MC (HR = 8,33; IC95%: 1,91 à 36,27) étaient les variables indépendamment associées au décès après l'arrêt du PRC. CONCLUSION: Dans cette population, les aspects sociodémographiques et la sévérité de la MC étaient des déterminants importants de l'arrêt du PRC et du décès.

Association of Cardiac Rehabilitation With Survival Among US Veterans.

Importance: Participation in cardiac rehabilitation (CR) programs at Veterans Affairs (VA) facilities is low. Most veterans receive CR through purchased care at non-VA programs. However, limited literature exists on the comparison of outcomes between VA and non-VA CR programs. Objective: To compare 1-year mortality and 1-year readmission rates for myocardial infarction or coronary revascularization between VA vs non-VA CR participants. Design, Setting, and Participants: This cohort study included 7320 patients hospitalized for myocardial infarction or coronary revascularization at the VA between 2010 and 2014 who did not die within 30 days of discharge and who participated in 2 or more CR sessions after discharge. The study excluded individuals hospitalized for ischemic heart disease after December 2014 when the VA Choice Act changed referral criteria for non-VA care. Data analysis was performed from November 2019 to January 2020. Exposures: Participation in 2 or more CR sessions within 12 months of discharge at a VA or non-VA facility. Main Outcomes and Measures: The 1-year all-cause mortality and 1-year readmission rates for myocardial infarction or coronary revascularization from date of discharge were compared between VA vs non-VA CR participants using Cox proportional hazards models with inverse probability treatment weighting. Results: The 7320 veterans with ischemic heart disease who participated in CR programs had a mean (SD) age of 65.13 (8.17) years and were predominantly white (6005 patients [82.0%]), non-Hispanic (6642 patients [91.0%]), and male (7191 patients [98.2%]). Among these 7320 veterans, 2921 (39.9%) attended a VA facility, and 4399 (60.1%) attended a non-VA CR facility. Black and Hispanic veterans were more likely to attend CR programs at VA facilities (509 patients [17.4%] and 378 patients [12.9%], respectively), whereas white veterans were more likely to attend CR programs at non-VA facilities (3759 patients [85.5%]). After inverse probability treatment weighting, rates of 1-year mortality were 1.7% among VA CR participants vs 1.3% among non-VA CR participants (hazard ratio, 1.32; 95% CI, 0.90-1.94; P = .15). Rates of readmission for myocardial infarction or revascularization during the 12 months after discharge were 4.9% among VA CR participants vs 4.4% among non-VA CR participants (hazard ratio, 1.06; 95% CI, 0.83-1.35; P = .62). Conclusions and Relevance: These findings suggest that rates of 1-year mortality and 1-year readmission for myocardial infarction or revascularization did not differ for participants in VA vs non-VA cardiac rehabilitation programs. Eligible patients with ischemic heart disease should participate in CR programs regardless of where they are provided.

Improvement in VO2peak predicts readmissions for cardiovascular disease and mortality in patients undergoing cardiac rehabilitation.

BACKGROUND: Improvement in exercise capacity is a main goal of cardiac rehabilitation but the effects are often lost at long-term follow-up and thus also the benefits on prognosis. We assessed whether improvement in VO2peak during a cardiac rehabilitation programme predicts long-term prognosis. METHODS AND RESULTS: We performed a retrospective analysis of 1561 cardiac patients completing cardiac rehabilitation in 2011-2017 in Copenhagen. Mean age was 63.6 (11) years, 74% were male and 84% had coronary artery disease, 6% chronic heart failure and 10% heart valve replacement. The association between baseline VO2peak and improvement after cardiac rehabilitation and being readmitted for cardiovascular disease and/or all-cause mortality was assessed with three different analyses: Cox regression for the combined outcome, for all-cause mortality and a multi-state model. During a median follow-up of 2.3 years, 167 readmissions for cardiovascular disease and 77 deaths occurred. In adjusted Cox regression there was a non-linear decreasing risk of the combined outcome with higher baseline VO2peak and with improvement of VO2peak after cardiac rehabilitation. A similar linear association was seen for all-cause mortality. Applying the multi-state model, baseline VO2peak and change in VO2peak were associated with risk of a cardiovascular disease readmission and with all-cause mortality but not with mortality in those having an intermediate readmission for cardiovascular disease. CONCLUSION: VO2peak as well as change in VO2peak were highly predictive of future risk of readmissions for cardiovascular disease and all-cause mortality. The predictive value did not extend beyond the next admission for a cardiovascular event.

Effect of pre-discharge cardiopulmonary fitness on outcomes in patients with ST-elevation myocardial infarction after percutaneous coronary intervention.

BACKGROUND: The purpose of this study was to analyze cardiopulmonary fitness in Phase I cardiac rehabilitation on the prognosis of patients with ST-Elevation Myocardial Infarction (STEMI) after percutaneous coronary intervention (PCI). METHODS: The study enrolled a total of 499 STEMI patients treated with PCI between January 2015 and December 2015. Patients were assigned to individualized exercise prescriptions (IEP) group and non-individualized exercise prescriptions (NIEP) group according to whether they accept or refuse individualized exercise prescriptions. We compared the incidence of major cardiovascular events between the two groups. IEP group were further divided into two subgroups based on prognosis status, namely good prognosis (GP) group and poor prognosis (PP) group. Key cardio-pulmonary exercise testing (CPX) variables that may affect the prognosis of patients were identified through comparison of the cardio-respiratory fitness (CRF). RESULTS: There is no significant difference in the incidence of cardio-genetic death, re-hospitalization, heart failure, stroke, or atrial fibrillation between the IEP and the NIEP group. But the incidence of total major adverse cardiac events (MACE) was significantly lower in the IEP group than in the NIEP group (P = 0.039). The oxygen consumption (VO2) at ventilation threshold (VT), minute CO2 ventilation (E-VCO2), margin of minute ventilation carbon dioxide production (△CO2), rest partial pressure of end-tidal carbon dioxide(R-PETCO2), exercise partial pressure of end-tidal carbon dioxide(E-PETCO2) and margin of partial pressure of end-tidal carbon dioxide(△PETCO2) were significantly higher in the GP subgroup than in the PP subgroup; and the slope for minute ventilation/carbon dioxide production (VE/VCO2) was significantly lower in GP subgroup than in PP subgroup (P = 0.010). The VO2 at VT, VE/VCO2 slope, E-VCO2, △CO2, R-PETCO2, E-PETCO2 and margin of partial pressure of end-tidal carbon dioxide CO2 (△PETCO2) were predictive of adverse events. The VO2 at VT was an independent risk factor for cardiovascular disease prognosis. CONCLUSIONS: Individualized exercise prescription of Phase I cardiac rehabilitation reduced the incidence of cardiovascular events in patients with STEMI after PCI. VO2 at VT is an independent risk factor for cardiovascular disease prognosis, and could be used as an important evaluating indicator for Phase I cardiac rehabilitation.

Impact of inpatient cardiac rehabilitation on Barthel Index score and prognosis in patients with acute decompensated heart failure.

BACKGROUND: Although cardiac rehabilitation (CR) can improve exercise capacity and quality of life in patients with chronic heart failure (HF), the long-term prognostic influence of inpatient CR on patients with acute decompensated HF (ADHF) is not well established. We examined the impact of inpatient CR on disability and prognosis in patients with ADHF. METHODS: A total of 171 patients admitted for ADHF underwent CR that included resistance training and aerobic exercise. Patient disability was evaluated using Barthel Index (BI) scores at pre- (BIpre) and post- (BIpost) rehabilitation. All-cause mortality was retrospectively recorded after discharge. RESULTS: In the study cohort (median age: 76 years), 46 patients experienced all-cause mortality during a median of 478 days of follow-up. Impaired BIpost (i.e., BI < 60) was significantly correlated with older age and lower albumin, hemoglobin, estimated glomerular filtration rate (eGFR), and B-type natriuretic peptide (BNP). In Kaplan-Meier analysis, impaired BIpre and BIpost were significantly associated with all-cause mortality. Better outcomes were observed for improved BI (ΔBI > 15) among patients with impaired baseline BI. BIpost was an independent predictor of all-cause mortality after adjusting for age, sex, eGFR, BNP, hemoglobin, albumin, and left ventricular ejection fraction. CONCLUSIONS: Inpatient CR led to improvements in disabilities among patients with ADHF. Baseline disabilities were associated with a poor prognosis. Greater improvements in BI to inpatient CR were significantly related to better outcomes in patients with impaired baseline BI. CR should be indicated for patients with ADHF.

Predictors of survival in patients undergoing cardiac rehabilitation after transcatheter aortic valve implantation.

AIMS: Cardiac rehabilitation may improve physical and functional recovery after transcatheter aortic valve implantation (TAVI), but outcome predictors in TAVI patients are usually based on assessments made before or at the time of TAVI without regard to cardiac rehabilitation referral. We aimed to assess exercise-based cardiac rehabilitation-derived parameters that may predict 3-year outcome in TAVI patients undergoing residential cardiac rehabilitation. METHODS AND RESULTS: In 95 consecutive TAVI patients (82.7 ±â€Š4.9 years, 65% women) who underwent a 3-week cardiac rehabilitation program, at 3-year follow-up 35 deaths occurred. Compared with survivors, nonsurvivors had longer stay in cardiac rehabilitation (29.5 ±â€Š12.3 vs. 21.6 ±â€Š7.5 days, P = 0.0001), worse serum creatinine at admission/discharge (1.59 ±â€Š0.86 vs. 1.26 ±â€Š0.43 mg/dl, P = 0.0164; 1.52 ±â€Š0.61 vs. 1.23 ±â€Š0.44 mg/dl, P = 0.011), higher Cumulative Illness Rated State Comorbidity Index (5.4 ±â€Š1.5 vs. 4.6 ±â€Š1.8, P = 0.036) and Barthel Index at admission/discharge (51.8 ±â€Š24.5 vs. 68.1 ±â€Š23.2, P = 0.0016; 73.5 ±â€Š27.2 vs. 88.6 ±â€Š15.3, P = 0.0007), higher Morse Fall Risk score (35.6 ±â€Š24 vs. 24.3 ±â€Š14.1, P = 0.0056), and were less likely to train above the median exercise workload (fit) (11 vs. 35%, P = 0.008) or perform the 6-min walk test (6MWT) at admission/discharge (NO-6MWT: 34 vs. 12%, P = 0.008) and walked less distance on admission (6MWT: 129.6 ±â€Š88.3 vs. 193.3 ±â€Š69.8 m, P = 0.008). Univariate predictors of 3-year survival were cardiac rehabilitation duration, serum creatinine, Cumulative Illness Rated State Comorbidity Index, Barthel Index and NO-6MWT at admission/discharge, 6MWT at admission, Morse Fall Risk score at discharge and fit. Multivariate analysis confirmed exercise tolerance, Barthel Index and sCr at discharge as predictors. CONCLUSION: In TAVI patients who undergo cardiac rehabilitation, lower exercise tolerance, higher Barthel Index and sCr at discharge may predict 3-year mortality.

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. We divided patients into hospitalised for heart failure in acute care only (group A) versus patients with one or more admission to cardiac rehabilitation for an in-hospital cardiac rehabilitation programme (group B). RESULTS: Of 140,552 incident cases, 100,843 (71%) were in group A and 39,709 (29%) in group B. Patients in group B had 3.26 ± 1.78 admissions to acute care before referral to an in-hospital cardiac rehabilitation programme. Male gender, age in women and comorbidities (more than two) were higher in group B ( P < 0.0001). Patients in group B had a higher number of interventional procedures ( P < 0.0001), drug prescription and outpatient visit rate ( P < 0.0001). Total mortality was 30% in group A versus 29% in group B. At Cox and logistic regression analyses, after adjustment for covariates, group B had a significantly lower risk of mortality (hazard ratio 0.5768, 95% confidence interval 0.5650-0.5888, P < 0.0001) and readmissions (0.7997, 0.7758-0.8244, P < 0.0001) than group A. CONCLUSION: This study showed in a large population of heart failure patients that in-hospital cardiac rehabilitation is associated with a reduction of all-cause mortality and rehospitalisations in heart failure. Given its potential significant benefit, referral of heart failure patients to an in-hospital cardiac rehabilitation programme should be promoted.

Targeting relatives: Impact of a cardiac rehabilitation programme including basic life support training on their skills and attitudes.

BACKGROUND: Training families of patients at risk for sudden cardiac death in basic life support (BLS) has been recommended, but remains challenging. This research aimed to determine the impact of embedding resuscitation training for patients in a cardiac rehabilitation programme on relatives' BLS skill retention at six months. DESIGN: Intervention community study. METHODS: Relatives of patients suffering acute coronary syndrome or revascularization enrolled on an exercise-based cardiac rehabilitation programme were included. BLS skills of relatives linked to patients in a resuscitation-retraining programme (G-CPR) were compared with those of relatives of patients in a standard programme (G-Stan) at baseline, following brief instruction and six months after. Differences in skill performance and deterioration and self-perceived preparation between groups over time were assessed. RESULTS: Seventy-nine relatives were included and complete data from 66 (G-Stan=33, G-CPR=33) was analysed. Baseline BLS skills were equally poor, improved irregularly following brief instruction and decayed afterwards. G-CPR displayed six-month better performance and lessened skill deterioration over time compared with G-Stan, including enhanced compliance with the BLS sequence ( p = 0.006 for group*time interaction) and global resuscitation quality ( p = 0.007 for group*time interaction). Self-perceived preparation was higher in G-CPR ( p = 0.002). CONCLUSIONS: Relatives of patients suffering acute coronary syndrome or revascularization enrolled on a cardiac rehabilitation programme showed poor BLS skills. A resuscitation-retraining cardiac rehabilitation programme resulted in relatives' higher BLS awareness, skill retention and confidence at six months compared with the standard programme. This may suggest a significant impact of this formula on the family setting and support the active role of patients to enhance health education in their environment.

Sex Differences in In-Hospital Management and Outcomes of Patients With Acute Coronary Syndrome.

BACKGROUND: Coronary heart disease is a leading cause of mortality among women. Systematic evaluation of the quality of care and outcomes in women hospitalized for acute coronary syndrome (ACS), an acute manifestation of coronary heart disease, remains lacking in China. METHODS: The CCC-ACS project (Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome) is an ongoing nationwide registry of the American Heart Association and the Chinese Society of Cardiology. Using data from the CCC-ACS project, we evaluated sex differences in acute management, medical therapies for secondary prevention, and in-hospital mortality in 82 196 patients admitted for ACS at 192 hospitals in China from 2014 to 2018. RESULTS: Women with ACS were older than men (69.0 versus 61.1 years, P<0.001) and had more comorbidities. After multivariable adjustment, eligible women were less likely to receive evidence-based acute treatments for ACS than men, including early dual antiplatelet therapy, heparins during hospitalization, and reperfusion therapy for ST-segment-elevation myocardial infarction. With respect to strategies for secondary prevention, eligible women were less likely to receive dual antiplatelet therapy, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, statins at discharge, and smoking cessation and cardiac rehabilitation counseling during hospitalization. In-hospital mortality rate was higher in women than in men (2.60% versus 1.50%, P<0.001). The sex difference in in-hospital mortality was no longer observed in patients with ST-segment-elevation myocardial infarction (adjusted odds ratio, 1.18; 95% CI, 1.00 to 1.41; P=0.057) and non-ST-segment elevation ACS (adjusted odds ratio, 0.84; 95% CI, 0.66 to 1.06; P=0.147) after adjustment for clinical characteristics and acute treatments. CONCLUSIONS: Women hospitalized for ACS in China received acute treatments and strategies for secondary prevention less frequently than men. The observed sex differences in in-hospital mortality were mainly attributable to worse clinical profiles and fewer evidence-based acute treatments provided to women with ACS. Specially targeted quality improvement programs may be warranted to narrow sex-related disparities in quality of care and outcomes in patients with ACS.

Exercise-based cardiac rehabilitation for adults with heart failure.

BACKGROUND: Chronic heart failure (HF) is a growing global health challenge. People with HF experience substantial burden that includes low exercise tolerance, poor health-related quality of life (HRQoL), increased risk of mortality and hospital admission, and high healthcare costs. The previous (2014) Cochrane systematic review reported that exercise-based cardiac rehabilitation (CR) compared to no exercise control shows improvement in HRQoL and hospital admission among people with HF, as well as possible reduction in mortality over the longer term, and that these reductions appear to be consistent across patient and programme characteristics. Limitations noted by the authors of this previous Cochrane Review include the following: (1) most trials were undertaken in patients with HF with reduced (< 45%) ejection fraction (HFrEF), and women, older people, and those with preserved (≥ 45%) ejection fraction HF (HFpEF) were under-represented; and (2) most trials were undertaken in the hospital/centre-based setting. OBJECTIVES: To determine the effects of exercise-based cardiac rehabilitation on mortality, hospital admission, and health-related quality of life of people with heart failure. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and three other databases on 29 January 2018. We also checked the bibliographies of systematic reviews and two trial registers. SELECTION CRITERIA: We included randomised controlled trials that compared exercise-based CR interventions with six months' or longer follow-up versus a no exercise control that could include usual medical care. The study population comprised adults (> 18 years) with evidence of HF - either HFrEF or HFpEF. DATA COLLECTION AND ANALYSIS: Two review authors independently screened all identified references and rejected those that were clearly ineligible for inclusion in the review. We obtained full papers of potentially relevant trials. Two review authors independently extracted data from the included trials, assessed their risk of bias, and performed GRADE analyses. MAIN RESULTS: We included 44 trials (5783 participants with HF) with a median of six months' follow-up. For this latest update, we identified 11 new trials (N = 1040), in addition to the previously identified 33 trials. Although the evidence base includes predominantly patients with HFrEF with New York Heart Association classes II and III receiving centre-based exercise-based CR programmes, a growing body of studies include patients with HFpEF and are undertaken in a home-based setting. All included studies included a no formal exercise training intervention comparator. However, a wide range of comparators were seen across studies that included active intervention (i.e. education, psychological intervention) or usual medical care alone. The overall risk of bias of included trials was low or unclear, and we downgraded results using the GRADE tool for all but one outcome.Cardiac rehabilitation may make little or no difference in all-cause mortality over the short term (≤ one year of follow-up) (27 trials, 28 comparisons (2596 participants): intervention 67/1302 (5.1%) vs control 75/1294 (5.8%); risk ratio (RR) 0.89, 95% confidence interval (CI) 0.66 to 1.21; low-quality GRADE evidence) but may improve all-cause mortality in the long term (> 12 months follow up) (6 trials/comparisons (2845 participants): intervention 244/1418 (17.2%) vs control 280/1427 (19.6%) events): RR 0.88, 95% CI 0.75 to 1.02; high-quality evidence). Researchers provided no data on deaths due to HF. CR probably reduces overall hospital admissions in the short term (up to one year of follow-up) (21 trials, 21 comparisons (2182 participants): (intervention 180/1093 (16.5%) vs control 258/1089 (23.7%); RR 0.70, 95% CI 0.60 to 0.83; moderate-quality evidence, number needed to treat: 14) and may reduce HF-specific hospitalisation (14 trials, 15 comparisons (1114 participants): (intervention 40/562 (7.1%) vs control 61/552 (11.1%) RR 0.59, 95% CI 0.42 to 0.84; low-quality evidence, number needed to treat: 25). After CR, a clinically important improvement in short-term disease-specific health-related quality of life may be evident (Minnesota Living With Heart Failure questionnaire - 17 trials, 18 comparisons (1995 participants): mean difference (MD) -7.11 points, 95% CI -10.49 to -3.73; low-quality evidence). Pooling across all studies, regardless of the HRQoL measure used, shows there may be clinically important improvement with exercise (26 trials, 29 comparisons (3833 participants); standardised mean difference (SMD) -0.60, 95% CI -0.82 to -0.39; I² = 87%; Chi² = 215.03; low-quality evidence). ExCR effects appeared to be consistent different models of ExCR delivery: centre vs. home-based, exercise dose, exercise only vs. comprehensive programmes, and aerobic training alone vs aerobic plus resistance programmes. AUTHORS' CONCLUSIONS: This updated Cochrane Review provides additional randomised evidence (11 trials) to support the conclusions of the previous version (2014) of this Cochane Review. Compared to no exercise control, CR appears to have no impact on mortality in the short term (< 12 months' follow-up). Low- to moderate-quality evidence shows that CR probably reduces the risk of all-cause hospital admissions and may reduce HF-specific hospital admissions in the short term (up to 12 months). CR may confer a clinically important improvement in health-related quality of life, although we remain uncertain about this because the evidence is of low quality. Future ExCR trials need to continue to consider the recruitment of traditionally less represented HF patient groups including older, female, and HFpEF patients, and alternative CR delivery settings including home- and using technology-based programmes.

The use of modern telemedicine technologies in an innovative optimal cardiac rehabilitation program for patients after myocardial revascularization: Concept and design of RESTORE, a randomized clinical trial.

Despite proven efficacy of cardiac rehabilitation (CR) in reducing the all-cause mortality in patients after myocardial revascularization, the penetration of CR, due to patient-related factors and referral rates remains limited. To improve the outcomes, home-based tele-rehabilitation (TR) has been proposed recently. In theory TR enhances the effects of standard CR procedures due to implementation of an intelligent monitoring system designed to ensure optimal training through on-demand transmission of vital signs, aimed at motivating the patients through daily schedule reminders, setting daily goals and creating a platform for mutual feedback. Several meta-analyses assessing various studies comparing these two methods (CR and TR) have proven that they are at least equally effective, with some of the research showing superiority of TR. Although there was a small sample size, lack of long-term follow-up, reporting effects of TR itself, no integration with tools designed for coaching, motivating and promoting a healthy lifestyle constitutes an important limitation. The latter carries a hopeful prognosis for improvement when utilizing a broad-spectrum approach, especially with use of dedicated technological solutions exploiting the fact of a large and yet rapidly increasing penetration of smartphones, mobile PCs and tablets in the population. The above-mentioned findings worked as the basis and rationale for commencing the RESTORE project aimed at developing and delivering state-of-the-art, comprehensive TR for patients after myocardial revascularization and evaluating its molecular aspect in view of how it influences the atherosclerosis progression attenuation. This paper presents the current state and rationale behind the project based on up-to-date TR efficacy data.

Effect of multidisciplinary cardiac rehabilitation on the response to cardiac resynchronization therapy.

BACKGROUND: Both cardiac resynchronization therapy (CRT) and Multidisciplinary Cardiac Rehabilitation (CR) beneficially influence symptomatic status, exercise capacity, quality of life, and heart failure readmission rates. However, the interaction between both therapies remain incompletely addressed. METHODS: Consecutive CRT patients implanted in a single tertiary care center were retrospectively analyzed. Patients were dived according to the participation in a structured CR-program following CRT-implant. The effect on functional status (New York Heart Association; NYHA-class), reverse remodeling (change in left ventricular ejection fraction; LVEF), and the combined endpoint of heart failure readmission and all-cause mortality was assessed after multivariate correction. RESULTS: A total of 655 patients were analyzed of whom 223(34%) did and 432(66%) did not participate in a structured multidisciplinary CR-program following implant. No adverse events relating to exercise training occurred during the CR-program. Patients who participated in the CR-program had a more pronounced improvement in NYHA-class at 6-months (P = 0.006), even after multivariate correction (ß = -0.144; 95% CI = [-0.270; -0.018]; P = 0.025). Maximal workload and VO2max on CPET at 6 months improved significantly even after adjustment (P < 0.001, respectively P = 0.017). At 6-months, CR associated with more improvement in LVEF (+11.9 ± 13 vs +14.5 ± 11; P = 0.008), however, this relationship was lost after multivariate correction (P = 0.136). During 36 ± 22 months follow-up, patients in the CR group had a higher event-free survival for the combined endpoint (P = 0.001), even after multivariate correction (adjusted HR = 0.547; CI = 0.366-0.818; P = 0.003). CONCLUSIONS: Following CRT-implant, the participation in a structured CR-program is safe and beneficially influences symptomatic response and clinical outcome. The beneficial effects of exercise training are potentially independent and additive to the beneficial reverse remodeling effect induced by CRT itself.

Cardiac rehabilitation for patients having cardiac surgery: a systematic review.

INTRODUCTION: Cardiac rehabilitation (CR) is recommended for all cardiac patients including patients after cardiac surgery. Since the effect of CR after cardiac surgery has not been well established yet, we conducted a systematic review on the effects of CR for patients after cardiac surgery compared to treatment as usual. EVIDENCE ACQUISITION: A systematic review of randomized clinical trials (RCTs), quasi-randomized and prospective observational studies in The Cochrane Library, PubMed/MEDLINE and EMBASE was undertaken until October 18th, 2017. Adults after any kind of cardiac surgery were included. Primary outcome was all-cause mortality, other outcomes were serious adverse events, health-related quality of life, work participation, functioning and costs/cost-effectiveness. Risk of bias was evaluated, and the quality of evidence was assessed by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria. EVIDENCE SYNTHESIS: Eighteen RCTs and 15 observational studies were included. Low risk of bias was only observed in one observational study. Meta-analysis of RCTs suggested no significant difference of CR compared to control on mortality (random-effects relative risk (RR) 0.93 (95% CI: 0.40-1.81), while observational studies suggested statistically significant beneficial effect associated with CR (random-effects RR=0.49, 95% CI: 0.35 - 0.68). CR did not significantly affect any of the other outcomes. Due to the limited data TSA could not be performed. CONCLUSIONS: The body of evidence does not allow us to reach any reliable conclusions about the effectiveness of CR following cardiac surgery. Future trials need to be conducted with low risks of bias and clearly defined outcomes.

Cardiac Rehabilitation Protects Against the Expansion of Abdominal Aortic Aneurysm.

BACKGROUND: Virtually no reports on the effects of exercise in patients with a small abdominal aortic aneurysm (AAA) exist. METHODS AND RESULTS: We conducted a retrospective cohort study on 1515 patients with a small AAA before surgery at 2 high-volume hospitals in Tokyo, Japan, from April 2004 to September 2015. A carefully modified cardiac rehabilitation program without excessive blood pressure elevation during exercise was prescribed to 50 patients with an AAA. Using propensity score matching, mortality and clinical outcomes, including AAA expansion rate, were compared between 2 groups: rehabilitation group and nonrehabilitation group. The background characteristics of the rehabilitation group (n=49) and the nonrehabilitation group (n=163) were almost identical. The risk for AAA repair was much lower in the rehabilitation group after matching (before matching: hazard ratio, 0.43; 95% confidence interval, 0.25-0.72; P=0.001; and after matching: hazard ratio, 0.19; 95% confidence interval, 0.07-0.50; P<0.001). AAA expansion rate was slower in the rehabilitation group (before matching: rehabilitation versus nonrehabilitation group, 2.3±3.7 versus 3.8±3.4 mm/y [P=0.008]; after matching: rehabilitation versus nonrehabilitation group, 2.1±3.0 versus 4.5±4.0 mm/y [P<0.001]). Elevation of blood pressure during exercise was positively correlated with AAA expansion rate after the rehabilitation program (r=0.569, P<0.001). CONCLUSIONS: Cardiac rehabilitation protects against the expansion of small AAAs and mitigates the risk associated with AAA repair, possibly because of the decreased elevation of blood pressure during exercise.

Slow Gait Speed and Cardiac Rehabilitation Participation in Older Adults After Acute Myocardial Infarction.

BACKGROUND: Lack of participation in cardiac rehabilitation (CR) and slow gait speed have both been associated with poor long-term outcomes in older adults after acute myocardial infarction (AMI). Whether the effect of CR participation on outcomes after AMI differs by gait speed is unknown. METHODS AND RESULTS: We examined the association between gait speed and CR participation at 1 month after discharge after AMI, and death and disability at 1 year, in 329 patients aged ≥65 years enrolled in the TRIUMPH (Translational Research Investigating Underlying Disparities in Recovery From Acute Myocardial Infarction: Patients' Health Status) registry. Among these patients, 177 (53.7%) had slow gait speed (<0.8 m/s) and 109 (33.1%) participated in CR. Patients with slow gait speed were less likely to participate in CR compared with patients with normal gait speed (27.1% versus 40.1%; P=0.012). In unadjusted analysis, CR participants with normal gait speed had the lowest rate of death or disability at 1 year (9.3%), compared with those with slow gait speed and no CR participation (43.2%). After adjustment for cardiovascular risk factors and cognitive impairment, both slow gait speed (odds ratio, 2.30; 95% confidence interval, 1.30-4.06) and non-CR participation (odds ratio, 2.34; 95 confidence interval, 1.22-4.48) were independently associated with death or disability at 1 year. The effect of CR on the primary outcome did not differ by gait speed (P=0.70). CONCLUSIONS: CR participation is associated with reduced risk for death or disability after AMI. The beneficial effect of CR participation does not differ by gait speed, suggesting that slow gait speed alone should not preclude referral to CR for older adults after AMI.
