Effectiveness of revascularization interventions compared with medical therapy in patients with ischemic cardiomyopathy: A systematic review protocol.

ABSTRACT:

Background

Cardiomyopathies is a group of heart diseases that directly affects the heart muscle, and their causes is not just high blood pressure, congenital and pericardial diseases but ischemic cardiomyopathy disease are also caused by vascular disorders, and to confirm the diagnosis, angiography is required. There are several methods for treating and controlling ischemic cardiomyopathy in world health systems and especially in the Iran health system, which include medical treatment, percutaneous coronary intervention (PCI), and coronary artery bypass graft (CABG).

Methods

This systematic review will includes observational and interventional studies in English and Persian languages and evaluates effectiveness of revascularization interventions and medical therapy in patients with ischemic cardiomyopathy. Animal studies will not be considered. In this systematic review, our sources of information will be electronic databases, trial registries, and different types of grey literature. An electronic search is performed through PubMed, Cochrane library, Scopus, Web of Science, EMBASE, Tufts Medical Center Cost-Effectiveness Analysis Registry, NHS Economic Evaluations Database. To integrate the results of studies with similar results, meta-analysis will be used, for which Comprehensive Meta-Analysis (CMA) software will be used. Results are provided using relative risk with a 95% confidence interval for information.

Results

The results of this systematic review will be published in a peer-reviewed journal.

Conclusion

To our knowledge, this systematic review will be the first to evaluate existing research on the effectiveness of revascularization interventions compared with medical therapy in patients with ischemic cardiomyopathy. The review will benefit patients, healthcare providers, and policymakers.

Project description:BackgroundRandomized studies have shown optimal medical therapy to be as efficacious as revascularization in stable ischemic heart disease (IHD). It is not known if these efficacy results are reflected by real-world effectiveness.ObjectiveTo evaluate the comparative effectiveness of routine medical therapy versus revascularization with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in stable IHD.DesignObservational cohort study.PatientsStable IHD patients from 1 October 2008 to 30 September 2011, identified using a Registry of all angiography patients in Ontario, Canada.InterventionRevascularization, defined as PCI/CABG within 90 days after index angiography.Main measuresDeath, myocardial infarction (MI) or repeat PCI/CABG. Revascularization was compared to medical therapy using a) multivariable Cox-proportional hazard models with therapy strategy treated as a time-varying covariate; and b) a propensity score matched analysis. Post-angiography medication use was determined.Key resultsWe identified 39,131 stable IHD patients, of whom 15,139 were treated medically, and 23,992 were revascularized (PCI = 15,604; CABG = 8,388). Mean follow-up was 2.5 years. Revascularization was associated with fewer deaths (HR 0.76; 95 % CI 0.68-0.84; p < 0.001) ,MIs (HR 0.78; 95 % CI 0.72-0.85; p < 0.001) and repeat PCI/CABG (HR 0.59; 95 % CI 0.50-0.70; p < 0.001) than medical therapy. In the propensity-matched analysis of 12,362 well-matched pairs of revascularized and medical therapy patients, fewer deaths (8.6 % vs 12.7 %; HR 0.75; 95 % CI 0.69-0.81; p < 0.001) , MIs (11.7 % vs 14.4 %; HR 0.84; 95 % CI 0.77-0.93 p < 0.001) and repeat PCI/CABG ( 17.4 % vs 24.1 %;HR 0.67; 95 % 0.63-0.71; p < 0.001) occurred in revascularized patients, over the 4.1 years of follow-up. The revascularization patients had higher uptake of clopidogrel (70.3 % vs 27.2 %; p < 0.001), ?-blockers (78.2 % vs 76.7 %; p = 0.010), and statins (94.7 % vs 91.5 %, p < 0.001) in the 1-year post-angiogram.ConclusionsStable IHD patients treated with revascularization had improved risk-adjusted outcomes in clinical practice, potentially due to under-treatment of medical therapy patients.

Project description:BACKGROUND:Patients with ischemic cardiomyopathy (ICM) may continue to experience persistent chest pain and/or dyspnea despite pharmacologic therapy and revascularization. We hypothesized that ranolazine would reduce anginal symptoms or dyspnea in optimally treated ICM patients. METHODS:In this randomized, double-blind, crossover-design pilot study, 28 patients with ICM (ejection fraction less or equal 40%) were included after providing informed consent. A total of 24 patients completed both placebo and ranolazine treatments and were analyzed. All patients were on treatment with a beta blocker, an angiotensin-converting enzyme inhibitor (or angiotensin receptor blocker), and at least one additional antianginal drug. After randomization, patients received up to 1,000 mg ranolazine orally twice a day, as tolerated, versus placebo. The primary end point was change in angina as assessed by the Seattle Angina Questionnaire (SAQ), or in dyspnea as assessed by the Rose Dyspnea Scale (RDS). Change in the RDS and SAQ score from baseline was compared, for ranolazine and placebo, using the Wilcoxon signed rank test or paired t-test. RESULTS:Patients had the following demographic and clinical variables: mean age of 71.5 years; male (82.1%); prior coronary bypass surgery (67.9%); prior coronary percutaneous intervention (85.7%); prior myocardial infarction (82.1%); diabetes (67.9%); and mean ejection fraction of 33.1%. No statistical difference was seen between baseline RDS score and that after placebo or ranolazine (n=20) (P?0.05). There was however, an improvement in anginal frequency (8/10 patients) (P=0.058), quality of life (8/10 patients) (P=0.048), and mean score of all components of the SAQ questionnaire (n=10) (P=0.047) with ranolazine compared with placebo. CONCLUSION:In optimally treated ICM patients with continued chest pain or dyspnea, ranolazine possibly had a positive impact on quality of life, a reduction in anginal frequency, and an overall improvement in the mean SAQ component score compared with baseline. Ranolazine did not change the dyspnea score compared with baseline.

Project description:Care transitions from the hospital to home are critical to the sustainability of our health care system. Ineffective care transitions can be caused by high incidences of post-discharge adverse events, by poor communication with patients, and/or by inadequate information transfer between providers from the hospital to home. Any one of these can lead to fragmented care, high readmission rates, increased visits to the emergency department, and ultimately poor patient outcomes. Despite the ongoing improvement efforts of health care organizations, the efficacy of person- and family-centered care transition interventions on the quality of care and on the patient experience are not known. The aim of this systematic review is to critically analyze the body of evidence regarding the effectiveness of person- and family-centered care transition interventions on the quality of care, and the experience of patients.We will conduct a systematic review using the Cochrane Handbook's guidelines and will adhere to a standardized reporting format: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A comprehensive search strategy will be conducted in the following databases: MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and the Cochrane Consumers and Communication Group. Following a two-step screening process, data including the full reference, objectives, target population, description of the intervention and control intervention, outcome measures, design, length of post-intervention follow-up period, and the study results will be extracted, synthesized, and reported. Risk of bias and quality of the studies will also be assessed.This systematic review will summarize and present the evidence base for person- and family-centered care transition interventions. This review will also inform further research and will lay the groundwork for more empirical studies on person- and family-centered care transitions. Specifically, the results of this systematic review may inform the development of measures to monitor safe and effective person- and family-centered transitions from the hospital to home. These results may also be important for policy makers, decision-makers, clinicians, and patients/families who are involved in navigating the health care system.PROSPERO CRD42017067990.

Project description:BackgroundMedical school typically presents students with a combination of academic and personal stressors that may lead to substandard mental health wellbeing. Meditation practices such as mindfulness facilitate a greater awareness of one's thoughts and feelings, thereby decreasing emotional reactivity. The use of mindfulness-based interventions delivered online has considerable potential in fostering self-care and helping medical students to handle mental health challenges. We examined the available evidence on the use of online mindfulness interventions in order to determine whether they are feasible and effective for improving medical students' mental health.MethodsWe performed a systematic review guided by PRISMA guidelines and utilised the following databases: ProQuest, Medline, PubMed, PsycINFO, Web of Science, IEEE Explore, Cochrane, and CINAHL. The key search terms used include mindfulness, cognitive behavioural therapy, acceptance and commitment therapy, online, web, virtual, internet cyber, app, medical students, residency students, and residents. English-language articles published in the last ten years that described online interventions for medical students or residents were included in the review.ResultsTwo studies describing the impact of online mindfulness interventions on medical students' mental health were identified. Research in this domain is nascent; available qualitative and quantitative evidence suggests benefits in self-compassion, perceived stress, cognitive skill use, mindfulness, creating coping mechanisms, and greater awareness of emotions and feelings. There was no evidence of the effectiveness of online mindfulness interventions on depression, anxiety and burnout. There was, however, general low program usage and participation tended to diminish near the conclusion of the interventions.ConclusionsThe evidence found in the systematic review exhibits the potential for online mindfulness interventions to be effective in addressing some mental health challenges of medical students. There was insufficient evidence to support the use of online mindfulness interventions for burnout, depression, and anxiety. Longitudinal studies with randomised controlled trials are required to generate stronger and robust evidence.

Project description:Background: The purpose of this review is to systematically examine the reported clinical effectiveness of pregnancy yoga. The review will use the FITT (frequency, intensity, time/duration and type) principle of physical activity to characterise the different types of yoga interventions that have been evaluated in the included studies. Studies will be categorised as effectiveness or efficacy studies and this continuum of efficacy versus effectiveness will be incorporated into the full review. Methods/design: The following electronic databases will be searched using a detailed search strategy: MEDLINE, PsycINFO, EMBASE, CINAHL, WHOLiS, AMED, ScieLo, ASSIA and Web of Science. Randomised control trials and quasi-experimental studies examining pregnancy yoga and reporting on effect will be included. Titles, abstracts and full articles will be screened by two investigators independently to identify eligible studies. The Cochrane Collaboration's Risk of Bias Assessment tool will be used to assess study quality. Quality of the evidence will be evaluated using the GRADE criteria. A standardised data extraction form will be used to extract data. Effect sizes will be estimated using mean differences for continuous outcomes, and relative risks for dichotomous outcome. Where possible, pooling of effect estimates will be done using a random effect model. The outcomes of interest are quality of life, stress, anxiety, depression, mode of birth, labour duration and pain management in labour. Discussion: This review will synthesise the best available evidence on the effectiveness of yoga during pregnancy and provide valuable high-quality information for clinicians and health policymakers. Findings will be disseminated through publication in a peer-reviewed journal and presentation at relevant conference proceedings. The review will make recommendations for the appropriate volume, intensity and type of pregnancy yoga for maximum effect and may have implications for policy and practice relating to pregnancy yoga as an intervention.
