Impacts of intensive follow-up on the long-term prognosis of percutaneous coronary intervention in acute coronary syndrome patients - a single center prospective randomized controlled study in a Chinese population

[Effects of Non-Pharmacological Interventions on Major Adverse Cardiac Events in Patients Underwent Percutaneous Coronary Intervention: Systematic Review and Meta-Analysis]

PURPOSE

In this study a systematic review and meta-analysis investigated the impact of non-pharmacological interventions on major adverse cardiac events (MACE) in patients with coronary artery disease who underwent percutaneous coronary intervention (PCI).

METHODS

A literature search was performed using PubMed, Cochrane Library, EMBASE, and Cumulative Index to Nursing & Allied Health Literature databases up to November 2023. The risk of bias was assessed using the Cochrane Risk of Bias 2.0 tool. Effect sizes and 95% confidence intervals were calculated using R software (version 4.3.2).

RESULTS

Eighteen randomized studies, involving 2,898 participants, were included. Of these, 16 studies with 2,697 participants provided quantitative data. Non-pharmacological interventions (education, exercise, and comprehensive) significantly reduced the risk of angina, heart failure, myocardial infarction, restenosis, cardiovascular-related readmission, and cardiovascular-related death. The subgroup meta-analysis showed that combined interventions were effective in reducing the occurrence of myocardial infarction (MI), and individual and group-based interventions had significant effects on reducing the occurrence of MACE. In interventions lasting seven months or longer, occurrence of decreased by 0.16 times, and mortality related to cardiovascular disease decreased by 0.44 times, showing that interventions lasting seven months or more were more effective in reducing MI and cardiovascular disease-related mortality.

CONCLUSION

Further investigations are required to assess the cost-effectiveness of these interventions in patients undergoing PCI and validate their short- and long-term effects. This systematic review underscores the potential of non-pharmacological interventions in decreasing the incidence of MACE and highlights the importance of continued research in this area (PROSPERO registration number: CRD42023462690).

Effectiveness of cardiac rehabilitation programs on medication adherence in patients with cardiovascular disease: A systematic review and meta-analysis

Background

Education to improve medication adherence is one of the core components of cardiac rehabilitation (CR) programs. However, the evidence on the effectiveness of CR programs on medication adherence is conflicting. Therefore, we aimed to summarize the effectiveness of CR programs versus standard care on medication adherence in patients with cardiovascular disease.

Methods

A systematic review and meta-analysis was conducted. Seven databases and clinical trial registries were searched for published and unpublished articles from database inception to 09 Feb 2022. Only randomised controlled trials and quasi-experimental studies were included. Two independent reviewers conducted the screening, extraction, and appraisal. The JBI methodology for effectiveness reviews and PRISMA 2020 guidelines were followed. A statistical meta-analysis of included studies was pooled using RevMan version 5.4.1.

Results

In total 33 studies were included with 16,677 participants. CR programs increased medication adherence by 14 % (RR = 1.14; 95 % CI: 1.07 to 1.22; p = 0.0002) with low degree of evidence certainty. CR also lowered the risk of dying by 17 % (RR = 0.83; 95 % CI: 0.69 to 1.00; p = 0.05); primary care and emergency department visit by mean difference of 0.19 (SMD = -0.19; 95 % CI: -0.30 to -0.08; p = 0.0008); and improved quality of life by 0.93 (SMD = 0.93; 95 % CI: 0.38 to 1.49; p = 0.0010). But no significant difference was observed in lipid profiles, except with total cholesterol (SMD = -0.26; 95 % CI: -0.44 to -0.07; p = 0.006) and blood pressure levels.

Conclusions

CR improves medication adherence with a low degree of evidence certainty and non-significant changes in lipid and blood pressure levels. This result requires further investigation.

Controlled pilot test of a translated cardiac rehabilitation education curriculum in percutaneous coronary intervention patients in a middle-income country delivered using WeChat: acceptability, engagement, satisfaction and preliminary outcomes

In China, despite the rapid increase in percutaneous coronary interventions (PCIs), cardiac rehabilitation (CR) is just burgeoning, leaving a need for comprehensive evidence-based education curricula. This pilot study assessed the acceptability of Simplified Chinese CR education delivered via booklets and videos on WeChat asynchronously and the impact on improving knowledge, risk factors, health behaviors and quality of life. In this pre-post, controlled, observational study, interested PCI patients received the 12-week intervention or usual care and WeChat without education. Participants completed validated surveys, including the Coronary Artery Disease Education-Questionnaire and Self-Management Scale. Acceptability (14 Likert-type items), engagement (minutes per week) and satisfaction were assessed in intervention participants. Ninety-six patients consented to participate (n = 49 intervention), of which 66 (68.8%) completed the follow-up assessments. Twenty-seven (77.1%) retained intervention participants engaged with the materials, rating content as highly acceptable (all means ≥4/5) and satisfactory (2.19 ± 0.48/3); those engaging more with the intervention were significantly more satisfied (P = 0.03). While participants in both groups achieved some improvements, only intervention participants had significant increases in disease-related knowledge, reductions in body mass index and triglycerides, as well as improvements in diet (all P < 0.05). In this first study validating the recently translated CR patient education intervention, acceptability and benefits have been supported.

Medication adherence in cardiovascular medicine

Cardiovascular disease is the leading cause of death globally. While pharmacological advancements have improved the morbidity and mortality associated with cardiovascular disease, non-adherence to prescribed treatment remains a significant barrier to improved patient outcomes. A variety of strategies to improve medication adherence have been tested in clinical trials, and include the following categories: improving patient education, implementing medication reminders, testing cognitive behavioral interventions, reducing medication costs, utilizing healthcare team members, and streamlining medication dosing regimens. In this review, we describe specific trials within each of these categories and highlight the impact of each on medication adherence. We also examine ongoing trials and future lines of inquiry for improving medication adherence in patients with cardiovascular diseases.

Nurse-led counseling for coronary artery disease patients: A 1-year follow-up study

Nurse-led counseling and systematic follow-up have been shown to reduce cardiovascular risk factor levels. The study aims were to investigate if cardiovascular risk factor levels could be reduced in patients with coronary artery disease with a nurse-led intervention and to report patients' evaluations of nurse-led counseling. The study design was a real-life longitudinal follow-up counseling intervention. Data were collected from November 2017 to May 2020. The nurse-led intervention and patients' follow-up time was 1 year. Of the 78 patients recruited, 74 completed the study. The most significant findings were in the levels of total cholesterol, low-density lipoprotein cholesterol, and triglycerides at every follow-up visit compared to their baseline levels and that waist circumference decreased during the 1-year follow-up. Patients assessed the quality of nurse-led counseling to be very good, though it decreased slightly during follow-up. The results suggest the integrated care path and specialized and primary care for coronary artery disease patients need further development. More research is needed on how to strengthen patients' self-management and what kind of counseling would best promote it.

Education interventions in Chinese cardiac patients on health behaviours, disease-related knowledge, and health outcomes: A systematic review and meta-analysis

OBJECTIVE

This systematic review and meta-analysis aimed to summarize and synthesize the available evidence in adult Chinese cardiac patients to determine the effect of education interventions on health behaviours, disease-related knowledge, self-efficacy, depressive symptoms, anxiety symptoms, health-related quality of life, morbidity, and mortality.

METHODS

Seven databases were searched from database inception until January 2020 for randomized controlled trials. Characteristics of education interventions were described and random-effects meta-analysis was performed where feasible.

RESULTS

Overall, 18 randomized controlled trials were included in this systematic review and suggested that education interventions are effective in improving patients' physical activity, dietary habits, medication behaviour, disease-related knowledge, and health-related quality of life. Meta-analysis of two studies demonstrated benefit on physical activity (standardized mean difference [SMD] 1.27, 95% confidence interval [CI] 1.06-1.48; participants = 422; I² = 0%), dietary habits (SMD 0.76, 95%CI 0.44-1.08; participants = 422; I² = 61%), and medication behaviour (mean difference [MD] 0.31, 95%CI 0.17-0.46; participants = 422; I² = 28%).

CONCLUSION

This study supports the benefits of education interventions for adult Chinese cardiac patients on health behaviours, disease-related knowledge, and health-related quality of life. Future studies should characterize their education interventions in detail to facilitate reproducibility and comparison.

PRACTICE IMPLICATIONS

This study identified the need for studies on the outcome of alcohol consumption and in Chinese immigrant populations.

Effect of pragmatic versus explanatory interventions on medication adherence in people with cardiometabolic conditions: a systematic review and meta-analysis

OBJECTIVE

To synthesise findings from randomised controlled trials (RCTs) of interventions aimed at increasing medication adherence in individuals with type 2 diabetes (T2DM) and/or cardiovascular disease (CVD). And, in a novel approach, to compare the intervention effect of studies which were categorised as being more pragmatic or more explanatory using the Pragmatic-Explanatory Continuum Indicator Summary-2 (PRECIS-2) tool, to identify whether study design affects outcomes. As explanatory trials are typically held under controlled conditions, findings from such trials may not be relatable to real-world clinical practice. In comparison, pragmatic trials are designed to replicate real-world conditions and therefore findings are more likely to represent those found if the intervention were to be implemented in routine care.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Ovid Medline, Ovid Embase, Web of Science and CINAHL from 1 January 2013 to 31 December 2018.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

RCTs lasting ≥3 months (90 days), involving ≥200 patients in the analysis, with either established CVD and/or T2DM and which measured medication adherence. From 4403 citations, 103 proceeded to full text review. Studies published in any language other than English and conference abstracts were excluded.

MAIN OUTCOME MEASURE

Change in medication adherence.

RESULTS

Of 4403 records identified, 34 studies were considered eligible, of which 28, including 30 861 participants, contained comparable outcome data for inclusion in the meta-analysis. Overall interventions were associated with an increase in medication adherence (OR 1.57 (95% CI: 1.33 to 1.84), p<0.001; standardised mean difference 0.24 (95% CI: -0.10 to 0.59) p=0.101). The effectiveness of interventions did not differ significantly between studies considered pragmatic versus explanatory (p=0.598), but did differ by intervention type, with studies that included a multifaceted rather than a single-faceted intervention having a more significant effect (p=0.010). The analysis used random effect models and used the revised Cochrane Risk of Bias Tool to assess study quality.

CONCLUSIONS

In this meta-analysis, interventions were associated with a significant increase in medication adherence. Overall multifaceted interventions which included an element of education alongside regular patient contact or follow-up showed the most promise. Effectiveness of interventions between pragmatic and explanatory trials was comparable, suggesting that findings can be transferred from idealised to real-word conditions.

Hypothetical model of perceived adherence to treatment among patients with coronary heart disease after a percutaneous coronary intervention

Aim

To test the hypothetical model of adherence to treatment among patients with coronary disease after percutaneous coronary intervention.

Design

A descriptive, explanatory, cross-sectional survey.

Methods

The study was conducted in 2013 with 416 patients in five hospitals in Finland. The adherence of patients with chronic disease instrument, the adherence visual analogue scale, the social support for people with coronary heart disease instrument, the EuroQoL five-dimensional scale and EuroQoL visual analogue scale were used. The data were analysed using descriptive statistic. The hypothetical model was tested using structural equation modelling.

Results

The hypothetical model explained 30% of perceived adherence to treatment. Structural equation modelling confirmed that motivation, support from physicians and next of kin had direct associations with adherence. Indirectly, informational support, results of care, perceived health, anxiety and depression were associated with adherence. The background variables associated with adherence were gender, relationship, physical activity, consumption of vegetables and consumption of alcohol.

Support from next of kin and nurses are significant predictors of long-term adherence to treatment in post-PCI patients

BACKGROUND

Adherence to treatment is a crucial factor in preventing the progression of coronary heart disease. More evidence of the predictors of long-term adherence is needed.

AIMS

The purpose of this study was to identify the predictive factors of adherence to treatment six years after percutaneous coronary intervention.

METHODS

Baseline data (n=416) was collected in 2013 and follow-up data in 2019 (n=169) at two university hospitals and three central hospitals in Finland. The self-reported Adherence of Patients with Chronic Disease Instrument was used. Data were analysed using descriptive statistics and binary logistic regression analysis.

RESULTS

The respondents reported higher adherence to a healthy lifestyle six years after percutaneous coronary intervention in comparison to four months post-percutaneous coronary intervention; adherence was seen in their healthy behaviour, such as decreased smoking and reduced alcohol consumption. Participating in regular follow-up control predicted adherence. Support from next of kin predicted physical activity and normal cholesterol levels; this outcome was associated with close relationships, which also predicted willingness to be responsible for treatment adherence. Women perceived lower support from nurses and physicians, and they had more fear of complications. Fear was more common among respondents with a longer duration of coronary heart disease. Physical activity and male gender were associated with perceived results of care.

CONCLUSION

Support from next of kin, nurses and physicians, results of care, responsibility, fear of complication and continuum of care predicted adherence to treatment in long term. These issues should be emphasised among women, patients without a close relationship, physically inactive and those with a longer duration of coronary heart disease.

Impacts of Clinical Pharmacist Intervention on the Secondary Prevention of Coronary Heart Disease: A Randomized Controlled Clinical Study

Coronary heart disease (CHD) is one of the leading causes of morbidity and mortality worldwide, and more efforts should be made to reduce the risk of cardiovascular events. This study aimed to investigate the impact of clinical pharmacist intervention on the prognosis of acute coronary syndrome (ACS) in Chinese patients with CHD. Two hundred and forty patients who had ACS were recruited. Participants were randomly assigned to the intervention group (n = 120) or the control group (n = 120). The intervention group received a medication assessment and education by the clinical pharmacist at discharge and telephone follow-ups at 1 week and 1 and 3 months after discharge. The control group received usual care. The primary outcomes of this study were the proportion of patients who had major adverse cardiovascular events (MACEs), including mortality, nonfatal myocardial infarction (MI), stroke, and unplanned cardiac-related rehospitalizations within 6 and 12 months after hospital discharge. Secondary outcome was self-reported medication adherence to evidence-based medications for CHD (antiplatelets, statins, β-blockers, and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers). Of 240 enrolled patients, 238 (98.3%) completed 6-month follow-up, and 235 (97.9%) completed 12-month follow-up. There were no significant differences between intervention and control groups in the percentages of patients who incurred MACEs within the 6-month follow-up (3.3% vs 7.6%, respectively, P = 0.145) or 12-month follow-up (10.9% vs 12.1%, respectively, P = 0.783). Significant improvements were found in the prescribing rates of β-blockers and all four classes of medications at discharge in the intervention group compared with the control group (P = 0.001 and P = 0.009, respectively). There was no significant difference between the intervention and control groups in the use of all four classes of medications at the 6-month follow-up (48.3% vs 45.8%, respectively, P = 0.691) and 12-month follow-up (47.9% vs 46.6%, respectively, P = 0.836). The use of β-blockers was nonsignificantly higher in the intervention group than in the control group at the 6-month follow-up (74.2% vs. 64.4%, P = 0.103) and 12-month follow-up (74.8% vs 63.8%, P = 0.068). Clinical pharmacist intervention had no significant effects on reduction in cardiovascular events among patients with CHD. Further studies with larger sample sizes and longer time frames for both intervention and follow-up are needed to validate the role of the clinical pharmacist in the morbidity and mortality of CHD.

Adherence to Treatment of Female Patients With Coronary Heart Disease After a Percutaneous Coronary Intervention

BACKGROUND

Adherence to treatment is essential to prevent the progression of coronary heart disease (CHD), which is the most common cause of death among women. Coronary heart disease in women has special characteristics: the conventional risk factors are more harmful to women than men, accumulation of risk factors is common, and women have nontraditional risk factors such as gestational diabetes and preeclampsia. In addition, worse outcomes, higher incidence of death, and complications after percutaneous coronary intervention have been reported more often among females than among male patients.

OBJECTIVE

The aim of this study was to test a model of adherence to treatment among female patients with CHD after a percutaneous coronary intervention.

METHODS

A cross-sectional, descriptive, and explanatory survey was conducted in 2013 with 416 patients with CHD, of which the 102 female patients were included in this substudy. Self-reported instruments were used to assess female patient adherence to treatment. Data were analyzed using descriptive statistics and a structural equation model.

RESULTS

Motivation was the strongest predictor for female patients' perceived adherence to treatment. Informational support, physician support, perceived health, and physical activity were indirectly, but significantly, associated with perceived adherence to treatment via motivation. Furthermore, physical activity was positively associated with perceived health, whereas anxiety and depression were negatively associated with it.

CONCLUSIONS

Secondary prevention programs and patient education have to take into account individual or unique differences. It is important to pay attention to issues that are known to contribute to motivation rather than to reply on education alone to improve adherence.

Cardioprotective medication adherence among patients with coronary heart disease in China: a systematic review

In China, poor cardioprotective medication adherence is a key reason for the high mortality rate of coronary heart disease (CHD). The aims of this systematic review are to (1) describe and synthesise factors that influence medication adherence among Chinese people with CHD, (2) evaluate the current status of intervention studies, and (3) discuss directions of future research to improve medication adherence. A comprehensive search using PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, Scopus, Global Health and PsycINFO was undertaken to describe poor adherence in China. Thirty-three eligible articles were included in the study. The review shows that there are multiple contributing factors to poor medication adherence, including patients' sociodemographic characteristics, health status and medication characteristics. In addition, from patients' perspective, lack of medication-related knowledge, such as the name, function, dosage and frequency, contributes to poor adherence. From physicians' perspective, a gap exists between CHD secondary prevention guidelines and clinical practice in China. Follow-up phone calls, educational lectures, booklets and reminder cards were common methods found to be effective in improving medication adherence. This systematic review indicates that cardioprotective medications were commonly prescribed as secondary prevention medication to patients with CHD in China, but adherence to these medications gradually decreased during a follow-up period. Therefore, more research should be conducted on how to establish high-quality health educational programmes aimed at increasing patients' medication adherence.

Assessing Prognosis of Acute Coronary Syndrome in Recent Clinical Trials: A Systematic Review

There is no recent comprehensive overview of contemporary clinical trials assessing short and long-term outcomes in patients with acute coronary syndrome (ACS). This paper reviews factors from recent clinical trials that influenced prognosis in patients with ACS. Cochrane and PubMed databases were screened systematically for clinical trials published in the English literature reporting on ACS prognosis. Two authors independently screened titles, abstracts, and full text. Studies meeting inclusion criteria evaluated the impact of modern practice on prognosis. In vitro and animal models studies, conference abstracts, imaging studies, and review articles were excluded. Disagreement in inclusion criteria was resolved by consensus. A large study of 8,859 patients showed no difference in all-cause mortality between 31 days and 2 years in patients with ST segment elevation myocardial infarction (STEMI) compared to those with non-ST segment elevation myocardial infarction (NSTEMI) or stable ischemic heart disease (SIHD). Other studies showed a significant increase in all-cause mortality in patients with STEMI within the first 30 days, with NSTEMI patients exhibiting a higher mortality rate compared to those with SIHD during the 2-year follow-up period. Our review found that women have a poorer short-term prognosis compared to men. Additionally, reports from patients receiving comprehensive and coordinated care showed longer survival rates. In view of the improved prognosis demonstrated for patients suffering from ACS, assessing prognosis in patients represents a formidable task in modern practice. Our review highlights the need for further evidence-based studies evaluating long-term outcomes on diagnostic and treatment strategies.

Comparative Effectiveness of the Core Components of Cardiac Rehabilitation on Mortality and Morbidity: A Systematic Review and Network Meta-Analysis

A systematic review and network meta-analysis (NMA) of randomized controlled trials (RCTs) evaluating the core components of cardiac rehabilitation (CR), nutritional counseling (NC), risk factor modification (RFM), psychosocial management (PM), patient education (PE), and exercise training (ET)) was undertaken. Published RCTs were identified from database inception dates to April 2017, and risk of bias assessed using Cochrane's tool. Endpoints included mortality (all-cause and cardiovascular (CV)) and morbidity (fatal and non-fatal myocardial infarction (MI), coronary artery bypass surgery (CABG), percutaneous coronary intervention (PCI), and hospitalization (all-cause and CV)). Meta-regression models decomposed treatment effects into the main effects of core components, and two-way or all-way interactions between them. Ultimately, 148 RCTs (50,965 participants) were included. Main effects models were best fitting for mortality (e.g., for all-cause, specifically PM (hazard ratio HR = 0.68, 95% credible interval CrI = 0.54⁻0.85) and ET (HR = 0.75, 95% CrI = 0.60⁻0.92) components effective), MI (e.g., for all-cause, specifically PM (hazard ratio HR = 0.76, 95% credible interval CrI = 0.57⁻0.99), ET (HR = 0.75, 95% CrI = 0.56⁻0.99) and PE (HR = 0.68, 95% CrI = 0.47⁻0.99) components effective) and hospitalization (e.g., all-cause, PM (HR = 0.76, 95% CrI = 0.58⁻0.96) effective). For revascularization (including CABG and PCI individually), the full interaction model was best-fitting. Given that each component, individual or in combination, was associated with mortality and/or morbidity, recommendations for comprehensive CR are warranted.

Temporal trends in secondary prevention in myocardial infarction patients discharged with left ventricular systolic dysfunction in Poland

Background

The proportion of patients discharged after myocardial infarction with left ventricular systolic dysfunction remains high and the prognosis is unfavourable. The aim of this study was to analyse the temporal trends in the treatment and outcomes of a nationwide cohort of patients.

Methods and results

Data from the Polish Registry of Acute Coronary Syndromes and Acute Myocardial Infarction in Poland Registry were combined to achieve complete information on inhospital course, treatment and outcomes. An all-comer population of patients discharged with left ventricular ejection fraction of 40% or less formed the sample population ( n = 28,080). The patients were analysed for the incidence of significant temporal trends and their possible consequences. The implementation of guideline-based treatment at discharge was high. In the post-discharge course a trend towards a higher frequency of percutaneous coronary intervention and a lower prevalence of planned coronary artery bypass grafting procedures was observed. The number of implantable cardioverter defibrillator/cardiac resynchronisation therapy defibrillator implantations was increasing. Cardiac rehabilitation was performed in 19–23% cases. The post-discharge outpatient care was based on general practitioner visits, with only 47.9–48.1% of patients attending an ambulatory cardiology specialist visit. In 12 months of observation the frequency of heart failure rehospitalisations was 17.5–19.1%, while the prevalence of rehospitalisations due to myocardial infarction decreased (8.3% in 2009 to 6.7% in 2013, P < 0.001). A trend towards lower all-cause mortality was observed. Assessment of composite outcomes (death, myocardial infarction, stroke or heart failure rehospitalisation) adjusted for sex and age at 12 months revealed a significant decreasing trend.

Conclusion

The overall prognosis in this population is improving slowly. This may be due to the increasing prevalence of guideline-based forms of secondary prevention. Efforts aimed at maintaining these trends are essential, as overall compliance with these guideline remains suboptimal.

Healthcare provider-led interventions to support medication adherence following ACS: a meta-analysis

We conducted a systematic review and meta-analysis to determine the effectiveness of healthcare provider-led (HCPs) interventions to support medication adherence in patients with acute coronary syndrome (ACS). A systematic search of Cochrane Library, Medline, EMBASE, PsycINFO, Web of Science, IPA, CINAHL, ASSIA, OpenGrey, EthOS, WorldCat and PQDT was undertaken. Interventions were deemed eligible if they included adult ACS patients, were HCP-led, measured medication adherence and randomised participants to parallel groups. Intervention content was coded using the Behaviour Change Technique (BCT) Taxonomy and data were pooled for analysis using random-effects models. Our search identified 8870 records, of which 27 were eligible (23 primary studies). A meta-analysis (n=9735) revealed HCP-led interventions increased the odds of medication adherence by 54% compared to control interventions (k=23, OR 1.54, 95% CI 1.26 to 1.88, I2=57.5%). After removing outliers, there was a 41% increase in the odds of medication adherence with moderate heterogeneity (k=21, OR 1.41, 95% CI 1.21 to 1.65, I2=35.3%). Interventions that included phone contact yielded (k=12, OR 1.63, 95% CI 1.25 to 2.12, I2=32.0%) a larger effect compared to those delivered exclusively in person. A total of 32/93 BCTs were identified across interventions (mean=4.7, SD=2.2) with 'information about health consequences' (BCT 5.1) (19/23) the most common. HCP-led interventions for ACS patients appear to have a small positive impact on medication adherence. While we were able to identify BCTs among interventions, data were insufficient to determine the impact of particular BCTs on study effectiveness.
