Use of Cardiac Rehabilitation by Medicare Beneficiaries After Myocardial Infarction or Coronary Bypass Surgery

Randomized controlled trial of a well-being intervention in cardiac patients

OBJECTIVE

Positive psychological well-being interventions have demonstrated promise in improving both psychological and physical health-related outcomes in patients with coronary artery disease (CAD), but evidence of the efficacy of these interventions with individuals with CAD is limited. As such, we developed an eight-week group-based intervention targeting eudaimonic aspects of psychological well-being in a randomized pilot trial. The primary aims of the trial were feasibility and acceptability, and we also explored the intervention's effectiveness on psychological outcomes.

METHOD

Participants were 40 CAD outpatients randomly assigned to the intervention (n = 20) or an attention-matched control group (n = 20). Feasibility was measured by rates of group session attendance and homework completion, and acceptability was assessed through participant ratings of intervention activities. Additional study outcomes, compared between groups, included psychological well-being, optimism, depression, and positive and negative affect.

RESULTS

The intervention met a priori criteria for feasibility and acceptability. The intervention was also associated with greater improvements in psychological well-being (β = -16.90; 95% Confidence Interval [CI] = -23.36, -10.44; p < .001, ES = 1.65), optimism (β = -8.80; 95% CI = -11.17, -6.43; t = -7.41; p < .001; ES = 2.34), and depression (β = 26.45; 95% CI = 20.97, 31.93; p < .001) immediately post-intervention, with sustained effects six weeks later.

CONCLUSIONS

These results indicate that the intervention was feasible, well-accepted, and effective in improving clinically relevant psychological outcomes in individuals with CAD. Future work should seek to replicate this work and assess general health-related and cardiac health-specific outcomes.

Effect of Initiating Cardiac Rehabilitation After Myocardial Infarction on Subsequent Hospitalization in Older Adults

PURPOSE

Outpatient cardiac rehabilitation (CR) participation after myocardial infarction (MI) reduces all-cause mortality; however, less is known about effects of CR on post-MI hospitalization. The study objective was to investigate effects of CR on hospitalization following acute MI among older adults.

METHODS

Medicare beneficiaries aged 65 to 88 yr hospitalized in 2008 with acute MI, who survived at least 60 d post-discharge, had a revascularization procedure during index hospitalization, and did not have an MI in previous year were eligible for this study. CR initiation was assessed in the 60 d post-discharge. Competing risk survival analysis was used to estimate the proportion of discharged beneficiaries hospitalized between the end of 60-d exposure window and December 31, 2009, treating death as a competing event.

RESULTS

The mean ± SD age of 32 851 Medicare beneficiaries meeting study criteria was 75 ± 6.0 yr, approximately half were male (52%), and the majority were white (88%). In this study, 21% of beneficiaries initiated CR within the exposure window. At 1 yr post-discharge, CR initiators had a lower risk of recurrent MI (4.2% [95% CI, 3.5-5.1]), cardiovascular (15.7% [95% CI, 14.3-17.2]), and all-cause (30.4% [95% CI, 28.8-32.1]) hospitalization than noninitiators (5.2% [95% CI, 5.0-5.5]; 18.0% [95% CI, 17.6-18.4]; and 33.2% [95% CI, 32.5-33.8], respectively). There was no difference in fracture risk (negative control outcome).

CONCLUSIONS

This study provides evidence that CR can reduce the 1-yr risk of cardiovascular and all-cause hospital admissions in Medicare aged MI survivors.

High-intensity interval training for patients with coronary artery disease: Finding the optimal balance

BACKGROUND

The optimal characteristics of high-intensity interval training (HIIT) for patients with coronary artery disease (CAD) within cardiac rehabilitation (CR) are unclear. We assessed a HIIT protocol designed to balance patient safety, efficacy and enjoyment.

METHODS

Twenty-nine patients with CAD completed 6-weeks (× 2 sessions per week) of HIIT within outpatient (phase 2) CR. HIIT comprised 15 repetitions × 30-seconds cycling at ∼85-90% maximum heart rate, interspersed with 30-seconds of active recovery. Key outcomes covered patient safety, efficacy (peak aerobic capacity, body composition, blood pressure and vascular function), and patient adherence and enjoyment.

RESULTS

No cardiovascular-related adverse events were reported in relation to HIIT sessions. Patients showed significant improvement in peak aerobic capacity (mean +12%, p < 0.001, effect size d = 0.38), blood pressure (brachial systolic -7mmHg, p < 0.001, d = -0.59) and total body fat (-4%, p < 0.001, d = -0.49). Central adaptations were prominent (aortic systolic BP -5mmHg, p = 0.001, d = -0.50; visceral fat -10%, p = 0.001, d = -0.41). Patient enjoyment of training was high (5.5 out of 7 using the Exercise Enjoyment Scale) and measures of affective state improved following training (assorted p < 0.018).

CONCLUSIONS

This HIIT protocol appears safe, effective and enjoyable for patients with CAD within CR. Improved aerobic fitness, blood pressure and body fat levels were observed indicating improved cardiovascular-risk. High patient enjoyment and improved mood suggest the HIIT could be sustainable for patients in the longer-term.

Gender Disparities in Cardiac Rehabilitation Among Older Women: Key Opportunities to Improve Care

Older women with cardiovascular disease experience lower referral, participation, and completion rates of cardiac rehabilitation (CR), despite its well-established benefits (improved morbidity, mortality, quality of life, and functional capacity). Multiple social and health care system barriers affect participation of this population, including limitations in accessibility and transportation, competing responsibilities as caregivers, and lack of insight among patients and provider regarding the value of CR. With continued advances in technology and the ubiquity of smartphones, alternative CR programs may be able to better overcome barriers that affect older women.

Cardiac Rehabilitation for Secondary Prevention of Cardiovascular Disease: 2019 Update

PURPOSE OF REVIEW

To provide updated information on the science and practice of cardiac rehabilitation (CR).

RECENT FINDINGS

Evidence continues to mount that supports the many benefits of CR as well as the important gap in delivering CR to all eligible patients. Recent studies have identified center-based and home-based strategies to improve the reach and impact of CR. Cardiac rehabilitation is a systematic, evidence-based approach to deliver effective secondary CVD preventive therapies to individuals with cardiovascular conditions. Because of a number of benefits that have been associated with CR, clinical practice guidelines strongly endorse CR services for eligible patients. Research supports CR as a high value service, with evidence of favorable clinical outcomes and costs. Unfortunately, a significant gap exists in CR participation due to a number of patient-, provider-, and system-level barriers. Solutions to most of these barriers have been identified and involve systematic approaches to CR delivery. The future is bright for CR as new strategies, new policies, and new methods of delivery continue to develop to help provide CR services to all eligible patients.

Voucher-Based Contingency Management is Efficacious but Underutilized in Treating Addictions

The United States lags far behind other industrialized countries on major markers of population health. Population health experts identify unhealthy behavior patterns (e.g., cigarette smoking, other substance use disorders, physical inactivity and poor food choices, nonadherence with recommended medical regimens) as the largest contributor to the status quo. Because these risk behaviors are overrepresented in socioeconomically disadvantaged and other vulnerable populations, they also increase health disparities. Hence, identifying evidence-based strategies to promote and sustain health-related behavior change is critical to improving U.S. population health. In this report, we review research demonstrating the efficacy of voucher-based contingency management delivered alone or in combination with other interventions for treating substance use disorders and other health-related behavior problems. The efficacy supporting these interventions is robust and discernible at the level of controlled randomized clinical trials and meta-analyses. Unfortunately, these evidence-based interventions are being underutilized in routine clinical care for substance use disorders, although they are used broadly in private-sector wellness programs and international programs to reduce chronic poverty. This report reviews the evidence supporting the efficacy of voucher-based contingency management using projects developed at the University of Vermont as exemplars and discusses dissemination of the model to public and private sector efforts to improve individual and population health.

Telerehabilitation with live-feed biomedical sensor signals for patients with heart failure: a pilot study

Background

Integrating biomedical sensors to a telerehabilitation platform allowed clinicians to receive real-time transmissions of the electrocardiogram (ECG) signal, oxygen saturation, and heart rate during an exercise program. These clinical data could be helpful to adjust and personalize the intensity of exercises to each patient's condition. The purpose of this study was to evaluate the feasibility and usefulness of biomedical sensors in telerehabilitation in patients with heart failure (HF).

Methods

Four participants with HF (mean age 66 years) followed the 12-week cardiac program using telerehabilitation, including sensors to monitor real-time vital signs during sessions. The exercise program included cardiovascular, strengthening and flexibility exercises. Participants were evaluated before the intervention and one month after the end of the program. Functional capacity was measured with Cardiopulmonary Exercise Testing (CPX), the 6-minute walk test (6MWT), and the sit to stand test (STST). Quality of life was objectified using the Kansas City Cardiomyopathy Questionnaire (KCCQ).

Results

Our main objective demonstrated that real-time biomedical sensors can be safely used by clinicians during a telerehabilitation session. Most participants showed a tendency to improve their physical capacities such as walking distance and lower limb muscular strength. As a main outcome of cardiac rehabilitation (CR), quality of life seems to improve after the 12-week intervention.

Conclusions

This study proved the feasibility of using telerehabilitation with real-time biomedical sensors as an alternative or a complement to the conventional CR program. Use of sensors allowed a safe environment for the patient and an adequate and personalized exercise prescription. Limitation in one-to-one supervision must be challenged in future clinical trials to demonstrate that telerehabilitation could be efficient for cardiac patients requiring more individual supervision than group sessions in a gymnasium.

Factors associated with non-attendance at exercise-based cardiac rehabilitation

Background

Despite its well-established positive effects, exercise-based cardiac rehabilitation (exCR) is underused in patients following an acute myocardial infarction (AMI). The aim of the study was to identify factors associated with non-attendance at exCR in patients post-AMI in a large Swedish cohort.

Methods

A total of 31,297 patients who have suffered an AMI, mean age 62.4 ± 4 years, were included from the SWEDEHEART registry during the years 2010-2016. Comparisons between attenders and non-attenders at exCR were done at baseline for the following variables: age, sex, body mass index, occupational status, smoking, previous diseases, type of index cardiac event and intervention, and left ventricular function. Distance of residence from the hospital and type of hospital were added as structural variables in logistic regression analyses, with non-attendance at exCR at one-year follow-up as dependent, and with individual and structural variables as independent variables.

Results

In total, 16,214 (52%) of the patients did not attend exCR. The strongest predictor for non-attendance was distance to the exCR centre (OR 1.75 [95% CI: 1.64-1.86]). Other predictors for non-attendance included smoking, history of stroke, percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), AMI or diabetes, male sex, being retired vs. being employed, and being followed-up at a county hospital. Patients with ST-elevation myocardial infarction (STEMI) and those intervened with PCI or CABG were more likely to attend exCR.

Conclusions

A distance greater than 16 km was associated with increased probability of non-attendance at exCR, as were smoking, a higher burden of comorbidities, and male sex. A better understanding of individual and structural factors can support the development of future rehabilitation services.

Disparities in the Use of Cardiac Rehabilitation after a Myocardial Infarction in the United States

The study's aim was to identify disparities in the use of cardiac rehabilitation (CR) services. Data were obtained from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) conducted through landline and cellular phones by the Centers for Disease Control and Prevention. Demographic, behavioral, and clinical variables were defined to explore disparities between CR users and non-users. Bivariate chi-square analyses and weighted multivariable logistic regression were used to identify disparities. Analyses were conducted using SAS version 9.4. There were 8506 individuals who had a myocardial infarction (MI) that completed the survey, and 2891 of these individuals reported using CR. The mean weighted CR utilization rate was 31.9% and varied from 17.9% (Hawaii) to 58.9% (Minnesota). Females (adjusted odds ratio (aOR) = 0.73; 0.6-0.88), African Americans (aOR = 0.63; 0.46-0.87), and those in-between the ages of 18 and 49 years-old were less likely to use CR (aOR = 0.54; 0.34-0.86) compared to their counterparts. Individuals who were high school graduates (aOR = 1.57; 1.19-2.07), attended college (aOR = 1.34; 1.01-1.79), or graduated college (aOR = 1.91; 1.41-2.61) were more likely to use CR compared to their counterparts. Non-high school graduates, females, African Americans, and those aged between 18 to 49 should be targeted to increase CR participation.

Effects of Exercise-Based Cardiac Rehabilitation in Patients with Acute Coronary Syndrome: A Meta-Analysis

BACKGROUND Acute coronary syndrome (ACS) has become an important cause of death from cardiovascular disease. Cardiac rehabilitation (CR) plays an essential role in ACS patients after treatment. Therefore, in order to detect the impact of CR on mortality and major adverse cardiac events in patients with ACS, we conducted this meta-analysis. MATERIAL AND METHODS We searched PubMed, Web of science, and EMBASE databases to obtain published research results from 2010 to August 2018 to determine the relevant research. Random-effects model or fixed-effects model were used to calculate relative risk (RR) and 95% confidence interval (CI). RESULTS Overall, a total of 25 studies with 55 035 participants were summarized in our meta-analysis. The results indicated that the hazard ratio (HR) of mortality significantly lower in the CR group than in the non-CR group (HR=-0.47; 95% CI=(-0.56 to -0.39; P<0.05). Fourteen studies on mortality rate showed exercise was associated with reduced cardiac death rates (RR=0.40; 95% CI=0.30 to 0.53; P<0.05). We found the risk of major adverse cardiac events (MACE) was lower in the rehabilitation group (RR=0.49; 95% CI=0.44 to 0.55; P<0.05). In 11 articles on CR including 8098 participants, the benefit in the CR group was greater than in the control group concerning revascularization (RR=0.69, 95% CI: 0.53 to 0.88; P=0.003). The recurrence rate of MI was reported in 13 studies, and the risk was lower in the CR group (RR=0.63, 95% CI: 0.57-0.70; P<0.05). CONCLUSIONS Our meta-analysis results suggest that CR is clearly associated with reductions in cardiac mortality, recurrence of MI, repeated PCI, CABG, and restenosis.

Usefulness of a Positive Psychology-Motivational Interviewing Intervention to Promote Positive Affect and Physical Activity After an Acute Coronary Syndrome

Most patients are not able to achieve recommended levels of physical activity following an acute coronary syndrome (ACS). Existing interventions to promote activity have not focused on promoting psychological well-being, which is independently linked to superior cardiac health. To address this gap, we developed and tested a combined positive psychology-motivational interviewing (PP-MI) intervention in post-ACS patients to assess its feasibility and explore potential benefits in an initial randomized trial. We compared a 12-week, phone-delivered, PP-MI intervention to an attention-matched, MI-based health education control condition among 47 post-ACS patients with low baseline health behavior adherence. Feasibility/acceptability were assessed through rates of session completion and participant session ratings; we also explored between-group differences in positive affect, other self-reported outcomes, and accelerometer-measured physical activity, through mixed effects regression models, at 12 and 24 weeks. PP-MI participants completed a mean of 10.0 (standard deviation 2.2) sessions (84%), and mean participant ratings of sessions' ease/utility were >8/10, above a priori thresholds for success. Compared with the control condition, PP-MI was associated with greater improvements in positive affect at 12 and 24 weeks (12 weeks: estimated mean difference [EMD] = 3.90 [SE = 1.95], p = 0.045, effect size [ES] = 0.56; 24 weeks: EMD = 7.34 [SE = 2.16], p <0.001, ES = 1.12). PP-MI was also associated with more daily steps at 12 weeks (EMD = 1842.1 steps/day [SE = 849.8], p = 0.030, ES = 0.76) and greater moderate-vigorous activity at 24 weeks (EMD = 15.1 minutes/day [SE = 6.8], p = 0.026, ES = 0.81). In conclusion, PP-MI was feasible in post-ACS patients and showed promising effects on well-being and physical activity; additional studies are needed to confirm these findings.

Irisin vs. Treadmill Exercise in Post Myocardial Infarction Cardiac Rehabilitation in Rats

BACKGROUND

Irisin is an exercise-induced myokine that could play a role in post-myocardial infarction (MI) cardiac rehabilitation.

AIM OF THE STUDY

We investigated the ability of dihydromyricetin to mimic the effects of exercise on raising serum irisin and on enhancing cardiac function and remodeling following MI in rats.

METHODS

MI was induced in albino rats by subcutaneous injection of isoproterenol (85 mg/kg) for 2 consecutive days at an interval of 24 h. One week post-MI, rats either underwent physical exercise by running on a motor-driven treadmill at 25 m/min, 30 min/d, 5 d/week or received orally dihydromyricetin 100 mg/kg/d, for 8 weeks.

RESULTS

Exercise and dihydromyricetin raised serum irisin 1.8 and 1.9 folds as compared to sedentary rats (p <0.001) with no difference between both regimens (p = 0.992). There was an improvement of cardiac remodeling where β-myosin heavy chain level was not different in exercise and dihydromyricetin groups from normal group (p = 0.695, p = 0.470). The heart rate variability domains increased back to normal. However, exercise was superior to dihydromyricetin in improving cardiac contractility by increasing carotid blood flow, stroke volume and cardiac output to be insignificant from normal rats (p = 0.899, p = 0.850, p = 0.912). Meanwhile, treatment with dihydromyricetin showed reduction by 29% of carotid blood flow, 24% of stroke volume and 25% of cardiac output compared to normal rats (p <0.001).

CONCLUSIONS

DHM could mimic the effect of exercise in stimulating irisin secretion but it is not as effective as exercise in improving myocardial contractility.

Cardiac Rehabilitation in Primary Care. Impact of an Intervention on Perceived Self-Efficacy

Cardiac rehabilitation is cost-effective and should be considered a part of the care system provided to patients who have suffered a myocardial infarction or another heart disease. The main variable to study was the scoring, prior to and after the intervention in the General Scale of Self-Efficacy by Baessler & Schwarzer. A clinical community trial that was open controlled and randomised was used. All adult subjects of both sexes who had completed a cardiac rehabilitation program for 12 months at the reference hospital were selected and offered to participate. The psychometric variables registered were the Salamanca screening questionnaire, the Hamilton Anxiety Rating Scale, and the Beck Depression Inventory. Eighty-nine subjects accepted to participate in the study (93.89% response rate), with an average age of 63.01 years (SD 8.75). Once the study was concluded, the main outcome was a difference in means of 6.09 points in the General Scale of Self-Efficacy (p < 0.0053, 96% confidence interval-4.1950-10.29), showing that the group exposed to the intervention reached a higher score in the above-mentioned scale. However, there were no significant differences (t-student 0.1211; p = 0.943) after the estimation and contrast of population means for score differences between the groups regarding the Hamilton scale. Similarly, there were no significant differences between the groups regarding the means obtained in the variable score difference in the Beck Depression Inventory (t-student -0.1281; p = 0.8987). The results showed an increase in those scores related to general self-efficacy among the population that completed the intervention program, as compared to the control group.

Effect of Cardiac Rehabilitation on Outcomes in Patients with ST-Elevation Myocardial Infarction

PURPOSE

Whether cardiac rehabilitation (CR) improves clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) has not been thoroughly evaluated. Moreover, few studies have sought to identify patients who would benefit most from CR among STEMI patients.

MATERIALS AND METHODS

Consecutively, 265 STEMI patients who underwent primary PCI with implantation of DESs and follow-up angiography were examined. Seventy-six patients (30%) who received CR were assigned to the CR+ group. Another 178 patients (70%) who did not participate in CR were assigned to the CR- group. Second generation DESs were implanted in 238 (94%) patients.

RESULTS

Major adverse cardiovascular events (MACEs), including death, myocardial infarction, and revascularization, were compared. The CR+ group tended to have lower MACE than the CR- group at 3 years, although the difference was not statistically significant (9.9% vs. 18.3%, hazard ratio=0.54, p=0.138). Subgroup analysis revealed a significant interaction according to CR and preprocedural thrombolysis in myocardial infarction (TIMI) flow (p value for interaction=0.011). In patients with low preprocedural TIMI flow (TIMI flow ≤1, n=161), those in the CR+ group had significantly lower MACE than those in the CR- group (p=0.005), whereas MACE was not different among patients with higher TIMI flow (TIMI flow ≥2, n=93).

CONCLUSION

CR including exercise training was associated with lower MACE, particularly in patients with lower preprocedural TIMI flow during primary PCI for STEMI in the current DES era.

Home-Based Cardiac Rehabilitation: A Scientific Statement From the American Association of Cardiovascular and Pulmonary Rehabilitation, the American Heart Association, and the American College of Cardiology

Cardiac rehabilitation (CR) is an evidence-based intervention that uses patient education, health behavior modification, and exercise training to improve secondary prevention outcomes in patients with cardiovascular disease. CR programs reduce morbidity and mortality rates in adults with ischemic heart disease, heart failure, or cardiac surgery but are significantly underused, with only a minority of eligible patients participating in CR in the United States. New delivery strategies are urgently needed to improve participation. One potential strategy is home-based CR (HBCR). In contrast to center-based CR services, which are provided in a medically supervised facility, HBCR relies on remote coaching with indirect exercise supervision and is provided mostly or entirely outside of the traditional center-based setting. Although HBCR has been successfully deployed in the United Kingdom, Canada, and other countries, most US healthcare organizations have little to no experience with such programs. The purpose of this scientific statement is to identify the core components, efficacy, strengths, limitations, evidence gaps, and research necessary to guide the future delivery of HBCR in the United States. Previous randomized trials have generated low- to moderate-strength evidence that HBCR and center-based CR can achieve similar improvements in 3- to 12-month clinical outcomes. Although HBCR appears to hold promise in expanding the use of CR to eligible patients, additional research and demonstration projects are needed to clarify, strengthen, and extend the HBCR evidence base for key subgroups, including older adults, women, underrepresented minority groups, and other higher-risk and understudied groups. In the interim, we conclude that HBCR may be a reasonable option for selected clinically stable low- to moderate-risk patients who are eligible for CR but cannot attend a traditional center-based CR program.

Financial Incentives to Increase Cardiac Rehabilitation Participation Among Low-Socioeconomic Status Patients: A Randomized Clinical Trial

OBJECTIVES

This study sought to examine the efficacy of financial incentives to increase Medicaid patient participation in and completion of cardiac rehabilitation (CR).

BACKGROUND

Participation in CR reduces morbidity, mortality, and hospitalizations while improving quality of life. Lower-socioeconomic status (SES) patients are much less likely to attend and complete CR, despite being at increased risk for recurrent cardiovascular events.

METHODS

A total of 130 individuals enrolled in Medicaid with a CR-qualifying cardiac event were randomized 1:1 to receive financial incentives on an escalating schedule ($4 to $50) for completing CR sessions or to receive usual care. Primary outcomes were CR participation (number of sessions completed) and completion (≥30 sessions completed). Secondary outcomes included changes in sociocognitive measurements (depressive/anxious symptoms, executive function), body composition (waist circumference, body mass index), fitness (peak VO₂) over 4 months, and combined number of hospitalizations and emergency department (ED) contacts over 1 year.

RESULTS

Patients randomized to the incentive condition completed more sessions (22.4 vs. 14.7, respectively; p = 0.013) and were almost twice as likely to complete CR (55.4% vs. 29.2%, respectively; p = 0.002) as controls. Incentivized patients were also more likely to experience improvements in executive function (p < 0.001), although there were no significant effects on other secondary outcomes. Patients who completed ≥30 sessions had 47% fewer combined hospitalizations and ED visits (p = 0.014), as reflected by a nonsignificant trend by study condition with 39% fewer hospital contacts in the incentive condition group (p = 0.079).

CONCLUSIONS

Financial incentives improve CR participation among lower-SES patients following a cardiac event. Increasing participation among lower-SES patients in CR is critical for positive longer-term health outcomes. (Increasing Cardiac Rehabilitation Participation Among Medicaid Enrollees; NCT02172820).

Regional variations in trajectories of long-term readmission rates among patients in England with heart failure

BACKGROUND

We aimed to compare the characteristics and types of heart failure (HF) patients termed "high-impact users", with high long-term readmission rates, in different regions in England. This will allow clinical factors to be identified in areas with potentially poor quality of care.

METHODS

Patients with a primary diagnosis of heart failure (HF) in the period 2008-2009 were identified using nationally representative primary care data linked to national hospital data and followed up for 5 years. Group-based trajectory models and sequence analysis were applied to their readmissions.

RESULTS

In each of the 8 NHS England regions, multiple discrete groups were identified. All the regions had high-impact users. The group with an initially high readmission rate followed by a rapid decline in the rate ranged from 2.5 to 11.3% across the regions. The group with constantly high readmission rate compared with other groups ranged from 1.9 to 12.1%. Covariates that were commonly found to have an association with high-impact users among most of the regions were chronic respiratory disease, chronic renal disease, stroke, anaemia, mood disorder, and cardiac arrhythmia. Respiratory tract infection, urinary infection, cardiopulmonary signs and symptoms and exacerbation of heart failure were common causes in the sequences of readmissions among high-impact users in all regions.

CONCLUSION

There is regional variation in England in readmission and mortality rates and in the proportions of HF patients who are high-impact users.

PCI Alternative Using Sustained Exercise (PAUSE): Rationale and trial design

Cardiovascular disease (CVD) currently claims nearly one million lives yearly in the US, accounting for nearly 40% of all deaths. Coronary artery disease (CAD) accounts for the largest number of these deaths. While efforts aimed at treating CAD in recent decades have concentrated on surgical and catheter-based interventions, limited resources have been directed toward prevention and rehabilitation. CAD is commonly treated using percutaneous coronary intervention (PCI), and this treatment has increased exponentially since its adoption over three decades ago. Recent questions have been raised regarding the cost-effectiveness of PCI, the extent to which PCI is overused, and whether selected patients may benefit from optimal medical therapy in lieu of PCI. One alternative therapy that has been shown to improve outcomes in CAD is exercise therapy; exercise programs have been shown to have numerous physiological benefits, and a growing number of studies have demonstrated reductions in mortality. Given the high volume of PCI, its high cost, its lack of effect on survival and the potential for alternative treatments including exercise, the current study is termed "PCI Alternative Using Sustained Exercise" (PAUSE). The primary aim of PAUSE is to determine whether patients randomized to exercise and lifestyle intervention have greater improvement in coronary function and anatomy compared to those randomized to PCI. Coronary function and anatomy is determined using positron emission tomography combined with computed tomographic angiography (PET/CTA). Our objective is to demonstrate the utility of a non-invasive technology to document the efficacy of exercise as an alternative treatment strategy to PCI.

Is Exercise Prescription in Cardiac Rehabilitation Influenced by Physical Capacity or Cardiac Intervention?

This study investigated the influence of cardiac intervention and physical capacity of individuals attending an Australian outpatient cardiac rehabilitation program on the initial exercise prescription. A total of 85 patients commencing outpatient cardiac rehabilitation at a major metropolitan hospital had their physical capacity assessed by an incremental shuttle walk test, and the initial aerobic exercise intensity and resistance training load prescribed were recorded. Physical capacity was lower in surgical patients than nonsurgical patients. While physical capacity was higher in younger compared with older surgical patients, there was no difference between younger and older nonsurgical patients. The initial exercise intensity did not differ between surgical and nonsurgical patients. This study highlights the importance of preprogram exercise testing to enable exercise prescription to be individualized according to actual physical capacity, rather than symptoms, comorbidities and age, in order to maximize the benefit of cardiac rehabilitation.

Stability in Cardiac Attributions Before and After Cardiac Rehabilitation

PURPOSE

This study examined temporal patterns in causal attributions generated by patients with cardiovascular disease before and after cardiac rehabilitation (CR).

DESIGN

Qualitative, descriptive survey.

METHODS

Eighty-six participants were asked what they believed was the primary cause of their cardiac events. Cardiac attributions were collected at the beginning of CR, at the end of CR, and 15 months after baseline.

FINDINGS

Content analyses showed that heredity and behavior were the most commonly generated causes. Most participants showed stability in attributions over time, although we found a trend for more participants endorsing behavioral attributions at the end of the study.

CONCLUSIONS

Cardiac attributions remain relatively stable across time.

CLINICAL RELEVANCE

Cardiac rehabilitation staff should approach patients differently, depending on their causal narratives. Some patients enter CR understanding that behavior played a causal role, whereas some do not. Encouraging appreciation of the importance of behavior in cardiovascular disease onset and recurrence is vital.

Apps and Mobile Health Technology in Rehabilitation: The Good, the Bad, and the Unknown

Although there is disparity in access to mobile health (mHealth) services among people with disabilities, several smartphone and tablet-based mHealth applications are available that may affect the care of patients in rehabilitation medicine. This article reviews the current evidence for and breadth of application-based mHealth interventions in rehabilitation medicine, including comprehensive self-management mHealth services; weight management mHealth services; diagnosis-specific mHealth services for individuals with brain, spinal cord, musculoskeletal, or other injury types; and nonmedical services to improve community and social integration.

Approaches to Address Premature Death of Patients When Assessing Patterns of Use of Health Care Services After an Index Event

BACKGROUND

Studies of the use of health care after the onset of disease are important for assessing quality of care, treatment disparities, and guideline compliance. Cohort definition and analysis method are important considerations for the generalizability and validity of study results. We compared different approaches for cohort definition (restriction by survival time vs. comorbidity score) and analysis method [Kaplan-Meier (KM) vs. competing risk] when assessing patterns of guideline adoption in elderly patients.

METHODS

Medicare beneficiaries aged 65-95 years old who had an acute myocardial infarction (AMI) in 2008 were eligible for this study. Beneficiaries with substantial frailty or an AMI in the prior year were excluded. We compared KM with competing risk estimates of guideline adoption during the first year post-AMI.

RESULTS

At 1-year post-AMI, 14.2% [95% confidence interval (CI), 14.0%-14.5%) of beneficiaries overall initiated cardiac rehabilitation when using competing risk analysis and 15.1% (95% CI, 14.8%-15.3%) from the KM analysis. Guideline medication adoption was estimated as 52.3% (95% CI, 52.0%-52.7%) and 53.4% (95% CI, 53.1%-53.8%) for competing risk and KM methods, respectively. Mortality was 17.0% (95%CI, 16.8%-17.3%) at 1 year post-AMI. The difference in cardiac rehabilitation initiation at 1-year post-AMI from the overall population was 0.1%, 1.7%, and 1.9% compared with 30-day survivor, 1-year survivor, and comorbidity-score restricted populations, respectively.

CONCLUSIONS

In this study, the KM method consistently overestimated the competing risk method. Competing risk approaches avoid unrealistic mortality assumptions and lead to interpretations of estimates that are more meaningful.

Platelet indices and function response to two types of high intensity interval exercise and comparison with moderate intensity continuous exercise among men after coronary artery bypass graft: A randomized trial

BACKGROUND

It has been indicated that the acute exercise increases the thrombotic events that stem from platelet hyper-reactivity. The present randomized controlled trial study was carried out with the aim to compare high-intensity interval exercise (HIIE) with moderate intensity continuous exercise (MICE) in terms of platelet indices and function in patients who had undergone post coronary artery bypass graft (CABG).

METHODS

30 men with a history of CABG were recruited and divided into 3 groups (MICE, HIIE-1, and HIIE-2). The MICE protocol consisted of running for 40 minutes with 65% of maximal heart rate (HRmax). Subjects in HIIE-1 group performed an interval exercise with work to rest ratio of 1:1 in which 10 rounds of running (95% HRmax) were followed by active recovery (35% HRmax). HIIE-2 subjects performed an interval exercise with work to rest ratio of 2:1 in which 7 rounds of running (85% HRmax) were followed by active recovery (45% HRmax). Before and immediately after the exercise protocols, blood samples were taken from subjects and analyzed to measure the variables.

RESULTS

Although platelet count (PLT) and hematocrit (HCT) were increased significantly after HIIE-1 and HIIE-2 in comparison to MICE (P < 0.050), the other platelet indices [mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT)] were not significantly changed among groups (P > 0.050). The platelet aggregation and fibrinogen were further increased after HIIE-1 and HIIE-2 as compared with MICE; however, such increment were significant between HIIE-2 and MICE (P < 0.050).

CONCLUSION

It seems that HIIE, regardless of the type, has higher thrombotic potentials compared with MICE. Accordingly, MICE is safer than HIIE for rehabilitation in patients undergoing CABG.

Predicting Long-Term Mortality, Morbidity, and Survival Outcomes Following a Cardiac Event: A Cardiac Rehabilitation Study

Background

Cardiac rehabilitation (CR) has been shown to decrease mortality and morbidity but estimations vary. While there is significant literature supporting short-term benefits, there is not a similarly body of research as to long-term (LT) benefits. Low participation rates in CR are due to several causes and evidence demonstrating positive LT outcomes could be a catalyst to increased participation rates.

Objective

To predict LT mortality, readmission, and survival benefits associated with CR participation in a nationally certified program.

Methods

Investigators collected mortality and hospital readmission data in a retrospective study to examine a cohort of cardiac patients following a myocardial infarction (MI), MI/percutaneous coronary intervention (PCI), and coronary artery bypass graft (CABG) up to 14 years ago. Hospital electronic medical record (EMR; n = 207) were used to measure hospital readmission outcome and State Health Department records (n = 361) for mortality and survival outcomes. Participation in CR, age, gender prior history of cardiac event, and diagnosis were used to predict readmission, mortality, and survival.

Results

Approximately half (52.1%) the sample participated in CR. Participants included 72% males, average age 68 years (38-91 years), and were predominantly Non-Hispanic white. CR participants attended an average of 20 sessions. CR group differed in diagnoses MI (58.5%), CABG (57.4%) and in prior history of heart disease (25.4%) from the non-cardiac rehabilitation (NCR) group (83.2%, 25.4%, 42.2%, respectively) (P < .05). After controlling for the covariates in logistic regression analyses, the CR group independently predicted lower all-cause mortality (odds ratio, OR = 0.22, 95% CI 0.12 to 0.39) and decreased hospital readmissions (OR = 0.48, 95% CI 0.24 to 0.96). After controlling for the covariates in survival analysis, the CR group significantly contributed to decreased likelihood of death hazard (hazard ratio = 0.36, 95% CI 0.24 to 0.54). Median survivor time for the participants was 5.91 years, SD = 3.81 years.

Conclusions

Participation in CR for middle age and elderly patients is associated with increased survival, a marked decrease in all-cause mortality, and a decrease in cardiovascular-related hospital readmission. A referral to a nationally certified outpatient CR program prior to hospital discharge and early enrollment may improve LT outcomes.

Class-based masculinity, cardiovascular health and rehabilitation

Men in economically advanced societies are more at-risk of dying prematurely due to heart disease than women, and this risk is inversely related to their socioeconomic status (SES). While the strong influence of socioeconomic factors on self-management of chronic diseases is important, the impact of masculinity must also be considered. This study examines the social variation in preventive health lifestyles of men from two contrasting socioeconomic groups who have suffered from a cardiovascular incident requiring hospitalization. It draws chiefly on Pierre Bourdieu's sociocultural theory of the practice (habitus and symbolic violence). Qualitative data was collected through 60 in-depth, semi-structured interviews with Canadian men (average age 57.3). Results indicate that participants from both socioeconomic groups share aspirations towards personal fulfilment (achieving a sense of security, preserving autonomy and gaining social recognition) after their heart incident, but apply different strategies in pursuit of these aspirations that have distinctive effects on healthy lifestyles. This study emphasise the importance of drawing on theoretical approaches in public health that have the potential to combine universal with context-specific views of human experience in order further understand health and lifestyle inequalities.

Patient Attitudes Toward Telemedicine-Delivered Cardiac Rehabilitation

BACKGROUND

Telemedicine-delivered cardiac rehabilitation (telemedicine-CR) provides an alternative pathway for patients who are unable to participate in conventional CR. Little is known regarding the relationships among potential participants' perceptions of barriers to CR participation, interest in telemedicine-CR, and self-efficacy beliefs toward the use of telemedicine. The purpose of this study was to identify if associations exist between these variables.

METHODS

A quantitative, correlational survey study was conducted using the Cardiac Rehabilitation Barriers Scale and a survey examining interest in and self-efficacy for telemedicine technologies. Eighty-three patients were invited to participate.

RESULTS

Twenty surveys (24%) were returned. Significant correlations were identified between interest in telemedicine-CR and self-efficacy beliefs for the use of live video links, rs(14) = .510, p = .044, and the Cardiac Rehabilitation Barriers Scale Comorbidity subscale, rs(18) = -.469, p = .037.

CONCLUSIONS

Higher self-efficacy for the use of video chat and fewer perceived comorbidity barriers were associated with greater interest in telemedicine-CR.

Cardiac rehabilitation fitness changes and subsequent survival

Aims

Assessments of cardiac rehabilitation (CR) in coronary heart disease (CHD) cohorts usually examine mortality in aggregate. This study examines the prognosis and characteristics of patients who enrolled and completed CR, stratified by their level of improvement in cardiorespiratory fitness (CRF) by examining the characteristics, outcomes and predictors of non-response in CRF (NonRes) compared with low-responders (LowRes) and high-responders (HighRes) after CR.

Methods and results

A total of 1171 CHD patients were referred for a phase II CR programme after therapy for an acute coronary syndrome, coronary artery bypass graft procedure or a percutaneous coronary intervention between 1 January 2000 and 30 June 2013 underwent cardiopulmonary exercise testing before and after CR. This cohort was divided according to absolute improvements in CRF (i.e. change in peak oxygen consumption expressed in mL⋅kg-1⋅min-1). Mortality was analysed after 0.5-13.4 years of follow-up (mean 6.4 years). A total of 266 (23%) subjects were NonRes. After adjustment for body mass index, age, gender, left ventricular ejection fraction and baseline CRF, NonRes, and LowRes had a statistically significant three-fold and two-fold higher mortality, respectively, when compared with HighRes (HighRes 8% vs. LowRes 17% vs. NonRes 22%; P < 0.001). Age, female gender, baseline CRF, hostility, and presence of diabetes were significant predictors of NonRes and LowRes. In addition, higher waist circumference was a predictor of NonRes.

Conclusion

Significant proportions of subjects referred to CR have no/low improvement in CRF and higher associated mortality risks. Greater attention is required to increase improvements in CRF following CR and avoid NonRes.

To what extent is the variation in cardiac rehabilitation quality associated with patient characteristics?

BACKGROUND

Huge variability in quality of service delivery of cardiac rehabilitation (CR) in the UK. This study aimed to ascertain whether the variation in quality of CR delivery is associated with participants' characteristics.

METHODS

Individual patient data from 1 April 2013 to 31 March 2014 were collected electronically from the UK's National Audit of Cardiac Rehabilitation database. Quality of CR delivery is categorised as low, middle, and high based on six service-level criteria. The study included a range of patient variables: patient demographics, cardiovascular risk factors, comorbidities, physical and psychosocial health measures, and index of multiple deprivation.

RESULTS

The chance that a CR patient with more comorbidities attended a high-quality programme was 2.13 and 1.85 times higher than the chance that the same patient attended a low- or middle-quality programme, respectively. Patients who participated in high-quality CR programmes tended to be at high risk (e.g. increased waist size and high blood pressure); high BMI, low physical activity levels and high Hospital Anxiety and Depression Scale scores; and were more likely to be smokers, and be in more socially deprived groups than patients in low-quality programmes.

CONCLUSIONS

These findings show that the quality of CR delivery can be improved and meet national standards by serving a more multi-morbid population which is important for patients, health providers and commissioners of healthcare. In order for low-quality programmes to meet clinical standards, CR services need to be more inclusive in respect of patients' characteristics identified in the study. Evaluation and dissemination of information about the populations served by CR programmes may help low-quality programmes to be more inclusive.

Effect of cardiac rehabilitation programme following elective percutaneous coronary angiography on depressive symptoms: A cohort study

Background

Depression is a common condition in cardiac patients. We investigated the effect of cardiac rehabilitation on depressive symptoms as detected by Beck depression inventory II score (BDI) in patients who underwent percutaneous coronary intervention (PCI).

Methods

In this cohort, 95 patients met our criteria. Patients were then studied in two groups based on their participation in the rehabilitation program to rehabilitation (exposure) and the control (non-exposure) groups. The control group consisted of those who only participated in the introductory session and decided not to continue the program. Finally, demographic and clinical parameters as well as the BDI scores were compared between the study groups.

Results

Data of 35 patients who completed rehabilitation program was compared with 60 patients who did not. There was no significant difference between the study groups regarding the demographic and clinical variables, except for a higher frequency of family history for CAD in the control group (p < 0.001). The frequency of the patients with no or mild depression was significantly higher in the rehabilitation group than the controls (p = 0.02). There was also a significant increase in the BDI score of the control group and a significant decrease in the rehabilitation group (p < 0.001). After adjustment for confounders (family history and severity of CAD), not attending the rehabilitation program was a strong risk factor for depression (OR = 10.8, 95% CI: 1.3, 88.5; P = 0.027).

Conclusion

Overall, this study showed that not attending cardiac rehabilitation program following elective PCI was a risk factor for depression.

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.

"When what is taken for granted disappears": women's experiences and perceptions after a cardiac event

BACKGROUND AND PURPOSE

On entering Cardiac Rehabilitation (CR), the female cardiac population shows greater fear of overexertion and sense of uncertainty than similarly affected men. The purpose of this study was to explore how women experienced the recovery process after a cardiac event and what impact the event had on bodily experiences.

METHODS

A qualitative, descriptive design, inspired by a phenomenological approach. Information was collected from 20 women through focus groups and individual in-depth interviews. The material was analyzed with a method of systematic text condensation.

RESULTS

The women's recovery after a CE could be a lonely and difficult process. Their own perspectives on what they need in the process is often overlooked, focus being on medical care and clinical recovery in the early phase. Returning home, the women suffered vulnerability, fragility, and insecurity, affecting well-being as well as activity levels. Lack of support and follow-up post-discharge seemed to disturb the progress of the recovery process.

CONCLUSIONS

Helping the women regain confidence in their new bodies, supporting the personal recovery processes, and bridging the gap between discharge and enrolling in a CR-program could reduce personal stress and withdrawal, thereby empowering more women to start and complete CR programs.

Predictors of cardiorespiratory fitness improvement in phase II cardiac rehabilitation

BACKGROUND

Cardiac rehabilitation (CR) improves cardiorespiratory fitness (CRF) and has been shown to reduce cardiovascular events and death. However, data about predictors of fitness improvement during CR are limited and conflicting. The objective of this study was to determine predictors of improvement in metabolic equivalents of task (METs) based on formal exercise testing throughout phase II CR.

METHODS

We retrospectively reviewed 20 671 patients enrolled in phase II CR at our center from 2006 to 2016. Patients who completed 36 sessions and had entry and exit exercise stress tests were included for study. The short form-36 (SF-36) questionnaire was used to assess quality-of-life. Univariate and multivariate regression analyses were performed to determine independent predictors of METs improvement.

RESULTS

Of the full cohort, 827 patients completed 36 sessions and had entry/exit stress test data. The majority of patients (N = 647, 78.2%) had improvement in METs (mean Δ 2.0 ± 1.2 METs), including patients ≥65 and < 65 years old (77% vs 79%, P = 0.46 for difference). METs improvement was negatively associated with body mass index, diabetes, left ventricular dysfunction, and poor baseline fitness; and positively associated with SF-36 score (P < 0.05 for all). After multivariable adjustment, improvement was no longer affected by age, ejection fraction, or baseline fitness. Patients with poor fitness (≤5 METS) and adequate fitness (> 5 METS) both had improvement, with no statistical difference between the groups (P = 0.36).

CONCLUSIONS

In a large cohort of phase II CR patients, improvement in CRF was seen in the majority of patients across all ages, genders, and levels of baseline fitness.

Trajectory Modelling to Assess Trends in Long-Term Readmission Rate among Abdominal Aortic Aneurysm Patients

Introduction

The aim of the study was to use trajectory analysis to categorise high-impact users based on their long-term readmission rate and identify their predictors following AAA (abdominal aortic aneurysm) repair. Methods. In this retrospective cohort study, group-based trajectory modelling (GBTM) was performed on the patient cohort (2006-2009) identified through national administrative data from all NHS English hospitals. Proc Traj software was used in SAS program to conduct GBTM, which classified patient population into groups based on their annual readmission rates during a 5-year period following primary AAA repair. Based on the trends of readmission rates, patients were classified into low- and high-impact users. The high-impact group had a higher annual readmission rate throughout 5-year follow-up. Short-term high-impact users had initial high readmission rate followed by rapid decline, whereas chronic high-impact users continued to have high readmission rate.

Results

Based on the trends in readmission rates, GBTM classified elective AAA repair (n=16,973) patients into 2 groups: low impact (82.0%) and high impact (18.0%). High-impact users were significantly associated with female sex (P=0.001) undergoing other vascular procedures (P=0.003), poor socioeconomic status index (P < 0.001), older age (P < 0.001), and higher comorbidity score (P < 0.001). The AUC for c-statistics was 0.84. Patients with ruptured AAA repair (n=4144) had 3 groups: low impact (82.7%), short-term high impact (7.2%), and chronic high impact (10.1%). Chronic high impact users were significantly associated with renal failure (P < 0.001), heart failure (P = 0.01), peripheral vascular disease (P < 0.001), female sex (P = 0.02), open repair (P < 0.001), and undergoing other related procedures (P=0.05). The AUC for c-statistics was 0.71.

Conclusion

Patients with persistent high readmission rates exist among AAA population; however, their readmissions and mortality are not related to AAA repair. They may benefit from optimization of their medical management of comorbidities perioperatively and during their follow-up.

Feasibility of a Smartphone-enabled Cardiac Rehabilitation Program in Male Veterans With Previous Clinical Evidence of Coronary Heart Disease

Cardiac rehabilitation (CR) is recommended for patients with coronary heart disease, however, participation among veterans remains poor. Smartphones may facilitate data transfer and communication between patients and providers, among other benefits. We evaluated the feasibility of a smartphone-enabled CR program in a population of veterans. Qualifying veterans were prospectively enrolled in a single-arm, nonrandomized feasibility study of a smartphone-enabled, home-based CR program, featuring an app with daily reminders to exercise, log vitals, and review educational materials. A coach remotely monitored patients through an online dashboard and scheduled telephone visits. Clinical end points were assessed as an exploratory aim. After 21 veterans provided informed consent, 18 were enrolled and successfully completed at least 30days of the program; 13 completed the entire 12-week intervention. Mean (standard deviation) age was 62 (7) years and 96% were male. Program completers logged a mean (standard deviation) of 3.5 (1.4) exercise sessions and 150 (86) exercise minutes per week. The majority (84%) of program completers reported being satisfied overall with the program. Mean functional capacity improved by 1.0 metabolic equivalents (5.3 to 6.3, 95% confidence interval 0.3 to 1.7; p = 0.008) and mean systolic blood pressure at rest improved by 9.6mm Hg (mean difference 9.6, 95% confidence interval -19.0 to -0.7; p = 0.049) among completers. Smartphone-enabled, home-based CR is feasible in veterans with heart disease and is associated with moderate to high levels of engagement and patient satisfaction.

Sexual rehabilitation for cardiac patients with erectile dysfunction: a randomised clinical trial

Background

Sexual dysfunction is common in patients with either ischaemic heart disease (IHD) or implantable cardioverter defibrillator (ICD) and has a negative impact on quality of life. Non-pharmacological treatment options are lacking. The purpose of this trial was to assess the effect of sexual rehabilitation versus usual care for males with erectile dysfunction and either IHD and/or ICD.

Methods

Participants with erectile dysfunction and IHD and/or ICD were randomised to 12 weeks of sexual rehabilitation consisting of physical exercise training, pelvic floor exercise and psychoeducation, or usual care. Primary outcome: sexual function by the International Index of Erectile Function (IIEF). Secondary outcome: sexual function by the Psychosocial Adjustment to Illness Scale. Exploratory outcomes: exercise capacity, pelvic floor strength/endurance, self-reported health and mental health.

Results

154 participants were included, mean age 61.6 years (SD 6.1). Sexual rehabilitation compared with usual care improved sexual function with a mean difference IIEF score of 6.7 (95% CI 3.1 to 10.4, p<0.0003) at 4 months between groups (unadjusted IIEF mean scores 36.4 vs 31.3) and a mean difference of 6.7, 95% CI 3.2 to 10.1 (p<0.0002) at 6 months between groups (unadjusted mean scores IIEF 37.1 vs 32.2). No effects were seen on the secondary outcome. Sexual rehabilitation improved exercise capacity on cycle ergometer measured by Watt max with a mean difference of 10.3, 95% CI 3.6 to 16.9 (p<0.003) and pelvic floor strength (p<0.01). No differences were seen on self-reported health and mental health.

Conclusion

Sexual rehabilitation compared with usual care improves sexual function and exercise capacity.

Tailored nurse-led cardiac rehabilitation after myocardial infarction results in better risk factor control at one year compared to traditional care: a retrospective observational study

BACKGROUND

Cardiac rehabilitation improves prognosis after an acute myocardial infarction (AMI), however, the optimal method of implementation is unknown. The aim of the study was to evaluate the effect of individually-tailored, nurse-led cardiac rehabilitation on patient outcomes.

METHOD

This single-centre retrospective observational study included 217 patients (62 ± 9 years, 73% men). All patients attended cardiac rehabilitation including at least two follow-up consultations with a nurse. Patients receiving traditional care (n = 105) had a routine cardiologist consultation, while for those receiving tailored care (n = 112) their need for a cardiologist consultation was individually evaluated by the nurses. Regression analysis was used to analyse risk factor control and hospital readmissions at one year.

RESULTS

Patients in the tailored group achieved better control of total cholesterol (- 0.1 vs + 0.4 mmol/L change between baseline (time of index event) and 12-14-month follow-up, (p = 0.01), LDL cholesterol (- 0.1 vs + 0.2 mmol/L, p = 0.02) and systolic blood pressure (- 2.1 vs + 4.3 mmHg, p = 0.01). Active smokers, at baseline, were more often smoke-free at one-year in the tailored group [OR 0.32 (0.1-1.0), p = 0.05]. There was a no significant difference in re-admissions during the first year of follow-up. In the tailored group 60% of the patients had a cardiologist consultation compared to 98% in the traditional group (p < 0.001). The number of nurse visits was the same in both groups, while the number of telephone contacts was 38% higher in the tailored group (p = 0.02).

CONCLUSION

A tailored, nurse-led cardiac rehabilitation programme can improve risk factor management in post-AMI patients.

Analysis of Cardiovascular Disease Risk Factors in Women

AIM:

Study the cardiovascular risk factors in a feminine population vulnerable to cardiovascular events particularly to evaluate the principal factors or possible confounding variables.

METHODS:

This is a cross-sectional descriptive study. Were analysed all the female patients from the Cardiovascular Rehabilitation Institute of Sports Medicine of Caxias do Sul who had the complete information on cardiovascular disease history, comorbidities and habits and who knew the complete gynaecological history by a phone interview.

RESULTS:

A group of 91 patients were analysed. About the comorbidities and habits, 45.2% of these patients presented some tobacco load, 82.4% are hypertensive, 61.5% are dyslipidemic, 25.3% are diabetic and the BMI average was 29.27 (overweight). Between the patients who undergone a hysterectomy and had an episode of the acute coronary syndrome (10 patients), 70% had the event after the procedure. Between the post-menopause women with at least one episode of the acute coronary syndrome, 80.5% (33 patients) had the first event after the menopause.

CONCLUSION:

We found multiple lifetime risk factors that predisposed the women of the sample to have cardiovascular disease. Between the women with specific to women risk factors and without, the prevalence of cardiovascular disease was very similar. This information supports the idea that these are just confounding factors of CVD and the principals involved are the genetic factors and habits. For this reason, the focus of CVD prevention and treatment should be directed towards these aspects.

Optimal Gender-Specific Strategies for the Secondary Prevention of Heart Disease in Women: A SYSTEMATIC REVIEW

BACKGROUND

There is a paucity of evidence on gender-specific, individually tailored secondary prevention (cardiac rehabilitation [CR]) services for women with heart disease. Women participate less in CR programs, thus increasing their risk of further cardiac events. This review aims to (1) determine the effectiveness of gender-specific interventions specifically designed for women with heart disease, delivered in outpatient CR settings; and (2) classify key elements of effective CR strategies/models for women with heart disease.

METHODS

Using the PRISMA guidelines, this is a systematic review of CR models tailored to women to improve cardiovascular risk. Four databases were searched for randomized controlled trials (RCTs) between January 1974 and July 2017 published in peer-reviewed English language journals.

RESULTS

Three RCTs comprising 725 women of gender-specific CR strategies were identified. Significant improvements were found in one-third (1 study) of the included multicomponent CR strategies for outcomes including general health, social functioning, vitality, mental health, depression, and quality of life.

CONCLUSION

Further large-scale RCTs are required to replicate positive findings and accurately assess the capacity for gender-specific multicomponent CR programs that incorporate participant-driven collaborative models to moderate psychological risk and improve functional capacity and quality of life for women with heart disease.
