Challenges adhering to a medication regimen following first-time percutaneous coronary intervention: A patient perspective

Role of Brain-Derived Neurotrophic Factor in Anxiety or Depression After Percutaneous Coronary Intervention

Anxiety or depression after percutaneous coronary intervention (PCI) is one of the key clinical problems in cardiology that need to be solved urgently. Brain-derived neurotrophic factor (BDNF) may be a potential biomarker for the pathogenesis and treatment of anxiety or depression after PCI. This article reviews the correlation between BDNF and cardiovascular system and nervous system from the aspects of synthesis, release and action site of BDNF, and focuses on the latest research progress of the mechanism of BDNF in anxiety or depression after PCI. It includes the specific mechanisms by which BDNF regulates the levels of inflammatory factors, reduces oxidative stress damage, and mediates multiple signaling pathways. In addition, this review summarizes the therapeutic potential of BDNF as a potential biomarker for anxiety or depression after PCI.

Perceived Determinants of Health-Related Behaviors Among Patients with Coronary Heart Disease After Percutaneous Coronary Intervention: A Longitudinal Qualitative Study

Purpose

Studies had reported some influencing factors of health behavior among patients with coronary heart disease(CHD) after percutaneous coronary intervention(PCI). However, considering that human perceptions are complex, unrestricted and dynamically changing. A longitudinal qualitative study was conducted to explore the determinants of health-related behaviors of patients after PCI and dynamic changes of these determinants at the 1st, 3rd, and 6th months.

Patients and Methods

Using purposive sampling, 18 patients undergoing PCI were interviewed. The conventional content analysis method was used to identify categories and subcategories. Semi-structured, face-to-face or telephone in-depth interviews were conducted at the cardiology unit of a tertiary referral hospital in Yunnan Province, China from March 2022 to January 2023.

Results

Seven categories with some subcategories were constructed from the data, categorized into three domains. Firstly, individual factors include (i) Personal coping with healthy lifestyle requirements (tried but failed; I can do it), (ii) individual perception and feeling toward disease (knowing about the disease; belief of cure; fears of relapse), and (iii) personal benefits (improved health; meaning of life). Secondly, social factors include (i) social facilitators (family resources; healthcare support), (ii) social barriers (inconvenient medical care service; conflicting information). Finally, cultural factors include (i) way of living (dietary habits; key roles of yan (cigarette) and jiu (alcohol) in Chinese society), (ii) way of thinking (fatalism and Confucian familism).

Conclusion

The determinants of health-related behaviors of patients after PCI are multifaceted and dynamic. Different interventions should be formulated to promote patients' adherence to health behaviors. Moreover, priority should be given to the impact of traditional Chinese philosophy on the health behaviors of patients after PCI, and the health promotion program for these patients should be culturally sensitive. In addition, future research should further explore the determinants of health behaviors among diverse ethnic minorities after PCI, which has not been fully inquired in this study.

Discharge Information About Adverse Drug Reactions Indicates Lower Self-Reported Adverse Drug Reactions and Fewer Concerns in Patients After Percutaneous Coronary Intervention

AIM

There are discrepancies between the information patients desire about adverse drug reactions (ADRs) and the information they receive from healthcare providers; this is an impediment to shared decision-making. This study aimed to establish whether patients received information about ADRs resulting from prescribed pharmacotherapy, before hospital discharge, after percutaneous coronary intervention (PCI) and to determine whether receiving information about ADRs was associated with incidence of self-reported ADRs or concerns related to prescribed pharmacotherapy.

METHODS

CONCARDPCI, a prospective multicentre cohort study including 3,417 consecutive patients after PCI, was conducted at seven high-volume referral PCI centres in two Nordic countries. Clinical data were collected from patients' medical records and national quality registries. Patient-reported outcome measures were registered 2 months (T1), 6 months (T2), and 12 months (T3) after discharge. Covariate-adjusted logistic regression yielded adjusted odds ratios (aORs) with 95% confidence intervals (CIs).

RESULTS

At discharge, 38% of participants had been informed about potential ADRs. For these patients, the incidence of self-reported ADRs was significantly lower at T1 (aOR 0.61, 95% CI 0.50-0.74; p<0.001), T2 (aOR 0.60, 95% CI 0.49-0.74; p<0.001), and T3 (aOR 0.57, 95% CI 0.46-0.71; p<0.001). Those who were not informed reported higher levels of concern about prescribed pharmacotherapy at all measuring points (p<0.001 for all comparisons). Those living alone (aOR 0.73, 95% CI 0.57-0.92; p=0.008), who were female (aOR 0.57, 95% CI 0.44-0.72; p<0.001), and with three or more versus no comorbidities (aOR 0.61, 95% CI 0.44-0.84; p=0.002) were less likely to receive information.

CONCLUSION

A substantial proportion of patients were not informed about potential ADRs from prescribed pharmacotherapy after PCI. Patients informed about ADRs had lower incidences of self-reported ADRs and fewer concerns about prescribed pharmacotherapy.

The quality of long-term counselling for percutaneous coronary intervention patients: A cross-sectional study

AIM

To compare the long-term counselling quality among the patients visited and not visited at cardiac nurse after percutaneous coronary intervention (PCI) and related factors one to two years after PCI.

DESIGN

An explorative, register-based cross-sectional study.

METHODOLOGY METHODS

A sample was drawn from the one university hospital's procedure register consisted of the patients undergone a PCI (n = 977). The data was collected by Counselling Quality Instrument (CQI) questionnaire by mail, and analysed by basic and multivariate methods.

FINDINGS RESULTS

Of the respondents (n = 459), less than half the patients (48.4%) visited at cardiac nurse one to two years after PCI as instructed in the national current care guidelines. Patients, who visited the nurse (n = 194) had higher satisfaction for counselling than the ones not visited (n = 70). Nevertheless, patients, especially those who had no dyslipidemia, had Unstable Angina Pectoris or Non-ST-elevated myocardial infarction or were out of the workforce, were unsatisfied with counselling, and needed more social support, patient-centred counselling and goal orientating implementation from the cardiac nurse. A half of the PCI patients (51.6%) did not visit the cardiac nurse at the primary health care.

PATIENT OR PUBLIC CONTRIBUTION

Cardiac nurses assisted the members of research group by assessing the questionnaire prior sending it to the patients and patients contributed by completing the questionnaires. We thank both parties for their contribution.

IMPLICATION FOR PROFESSION AND PATIENT CARE

This study demonstrated, that patients out of the workforce and having emergency PCI are in need for better quality counselling, concentrating on social support, patient-centred counselling and goal orientating implementation from the cardiac nurse. Those patients, who did not visit the cardiac nurse, should be offered easier access to cardiac nurse for example, by novel digital solutions.

Bleeding risk in patients prescribed dual antiplatelet therapy and triple therapy after coronary interventions: the ADAPTT retrospective population-based cohort studies

Background

Bleeding among populations undergoing percutaneous coronary intervention or coronary artery bypass grafting and among conservatively managed patients with acute coronary syndrome exposed to different dual antiplatelet therapy and triple therapy (i.e. dual antiplatelet therapy plus an anticoagulant) has not been previously quantified.

Objectives

The objectives were to estimate hazard ratios for bleeding for different antiplatelet and triple therapy regimens, estimate resources and the associated costs of treating bleeding events, and to extend existing economic models of the cost-effectiveness of dual antiplatelet therapy.

Design

The study was designed as three retrospective population-based cohort studies emulating target randomised controlled trials.

Setting

The study was set in primary and secondary care in England from 2010 to 2017.

Participants

Participants were patients aged ≥ 18 years undergoing coronary artery bypass grafting or emergency percutaneous coronary intervention (for acute coronary syndrome), or conservatively managed patients with acute coronary syndrome.

Data sources

Data were sourced from linked Clinical Practice Research Datalink and Hospital Episode Statistics.

Interventions

Coronary artery bypass grafting and conservatively managed acute coronary syndrome: aspirin (reference) compared with aspirin and clopidogrel. Percutaneous coronary intervention: aspirin and clopidogrel (reference) compared with aspirin and prasugrel (ST elevation myocardial infarction only) or aspirin and ticagrelor.

Main outcome measures

Primary outcome: any bleeding events up to 12 months after the index event. Secondary outcomes: major or minor bleeding, all-cause and cardiovascular mortality, mortality from bleeding, myocardial infarction, stroke, additional coronary intervention and major adverse cardiovascular events.

Results

The incidence of any bleeding was 5% among coronary artery bypass graft patients, 10% among conservatively managed acute coronary syndrome patients and 9% among emergency percutaneous coronary intervention patients, compared with 18% among patients prescribed triple therapy. Among coronary artery bypass grafting and conservatively managed acute coronary syndrome patients, dual antiplatelet therapy, compared with aspirin, increased the hazards of any bleeding (coronary artery bypass grafting: hazard ratio 1.43, 95% confidence interval 1.21 to 1.69; conservatively-managed acute coronary syndrome: hazard ratio 1.72, 95% confidence interval 1.15 to 2.57) and major adverse cardiovascular events (coronary artery bypass grafting: hazard ratio 2.06, 95% confidence interval 1.23 to 3.46; conservatively-managed acute coronary syndrome: hazard ratio 1.57, 95% confidence interval 1.38 to 1.78). Among emergency percutaneous coronary intervention patients, dual antiplatelet therapy with ticagrelor, compared with dual antiplatelet therapy with clopidogrel, increased the hazard of any bleeding (hazard ratio 1.47, 95% confidence interval 1.19 to 1.82), but did not reduce the incidence of major adverse cardiovascular events (hazard ratio 1.06, 95% confidence interval 0.89 to 1.27). Among ST elevation myocardial infarction percutaneous coronary intervention patients, dual antiplatelet therapy with prasugrel, compared with dual antiplatelet therapy with clopidogrel, increased the hazard of any bleeding (hazard ratio 1.48, 95% confidence interval 1.02 to 2.12), but did not reduce the incidence of major adverse cardiovascular events (hazard ratio 1.10, 95% confidence interval 0.80 to 1.51). Health-care costs in the first year did not differ between dual antiplatelet therapy with clopidogrel and aspirin monotherapy among either coronary artery bypass grafting patients (mean difference £94, 95% confidence interval -£155 to £763) or conservatively managed acute coronary syndrome patients (mean difference £610, 95% confidence interval -£626 to £1516), but among emergency percutaneous coronary intervention patients were higher for those receiving dual antiplatelet therapy with ticagrelor than for those receiving dual antiplatelet therapy with clopidogrel, although for only patients on concurrent proton pump inhibitors (mean difference £1145, 95% confidence interval £269 to £2195).

Conclusions

This study suggests that more potent dual antiplatelet therapy may increase the risk of bleeding without reducing the incidence of major adverse cardiovascular events. These results should be carefully considered by clinicians and decision-makers alongside randomised controlled trial evidence when making recommendations about dual antiplatelet therapy.

Limitations

The estimates for bleeding and major adverse cardiovascular events may be biased from unmeasured confounding and the exclusion of an eligible subgroup of patients who could not be assigned an intervention. Because of these limitations, a formal cost-effectiveness analysis could not be conducted.

Future work

Future work should explore the feasibility of using other UK data sets of routinely collected data, less susceptible to bias, to estimate the benefit and harm of antiplatelet interventions.

Trial registration

This trial is registered as ISRCTN76607611.

MicroRNA-30e-3p reduces coronary microembolism-induced cardiomyocyte pyroptosis and inflammation by sequestering HDAC2 from the SMAD7 promoter

This study investigates the mechanism by which microRNA (miR)-30e-3p reduces coronary microembolism (CME)-induced cardiomyocyte pyroptosis and inflammation. Cardiac function tests, histological staining, and transmission electron microscopy were performed on CME-model rats injected with adeno-associated viral vectors. Cardiomyocytes were transfected 24 h before a cellular model of pyroptosis was established via treatment with 1 μg/mL lipopolysaccharide (LPS) for 4 h and 5 mM ATP for 30 min. Pyroptosis, inflammation, and Wnt/β-catenin signaling in cardiomyocytes were detected. Dual-luciferase reporter assays and/or RNA pull-down assays were performed to verify the binding of miR-30e-3p to HDAC2 mRNA or HDAC2 to the SMAD7 promoter. Chromatin immunoprecipitation was used to assess the level of H3K27 acetylation at the SMAD7 promoter. miR-30e-3p and SMAD7 expression levels were downregulated and HDAC2 expression was upregulated with CME. The overexpression of miR-30e-3p restored cardiac functions in CME-model rats and reduced serum cTnI, IL-18, and IL-1β levels, microinfarcts, inflammatory cell infiltration, apoptosis, collagen content, and GSDMD-N, cleaved caspase-1, and NLRP3 expression in the myocardium, but these effects were reversed by SMAD7 knockdown. The overexpression of miR-30e-3p or knockdown of HDAC2 reduced LDH, IL-18, and IL-1β secretion, propidium iodide intake, and GSDMD-N, NLRP3, cleaved caspase-1, Wnt3a, Wnt5a, and β-catenin expression in the cardiomyocyte model. miR-30e-3p inhibited the expression of HDAC2 by binding HDAC2 mRNA. HDAC2 repressed the expression of SMAD7 by catalyzing H3K27 deacetylation at the SMAD7 promoter. miR-30e-3p, by binding HDAC2 to promote SMAD7 expression, reduces CME-induced cardiomyocyte pyroptosis and inflammation.

Implementing a newly prescribed cardiovascular medicine in daily routine: The patient perspective at readmission to primary care

BACKGROUND

Readmission to primary care is challenging for patients due to involvement of multiple healthcare providers across different settings and implementing new medicines into their daily routine. Elucidating patients' needs is crucial to tailor counseling support.

OBJECTIVE

To explore the patient perspectives on implementing a newly prescribed cardiovascular medicine into their daily routine at readmission to primary care.

METHODS

A qualitative study was performed within the outpatient pharmacy. Adult patients who were prescribed a new cardiovascular medicine by their treating hospital physician at hospital discharge or during an outpatient clinic visit were eligible to participate. Purposive sampling was applied to equally distribute adherence-influencing factors. Patients were interviewed by telephone and inclusion continued until theoretical data saturation. An adapted Greenhalgh framework for implementation research was used for a thematic content analysis by conceptualizing the new medicine as an innovation that requires implementation by a patient (adopter).

RESULTS

Data saturation was reached at 44 patients of which 19 discontinued their new medicine at the time of the interview. Reasons for discontinuing included: side-effects, insufficient efficacy or negligence. Patients considered a lack of basic knowledge on their newly prescribed cardiovascular medicine as a major barrier for adopting it into their daily routine. They were in need of information on risks and benefits of their new medicine. A noticeable effect and tailored counseling facilitated patients in taking their medicine as prescribed. Patients mentioned personalized organizing tools and routinization of medication intake as important success factors for addressing their practical challenges with their new medicine.

CONCLUSIONS

By applying the adapted Greenhalgh framework, this study provided a unique and structured insight in patients' barriers and facilitators that could influence their ability to implement a new cardiovascular medicine at readmission to primary care. This knowledge enables pharmacists to tailor their patient support and provide individualized patient counseling.

Perceptions of generic medicines and medication adherence after percutaneous coronary intervention: a prospective multicentre cohort study

OBJECTIVE

To determine patient perceptions of generic medicines 2 and 6 months after percutaneous coronary intervention (PCI), and to determine whether these perceptions moderate medication adherence.

DESIGN

Prospective multicentre cohort study with repeated measures of perceptions of generic medicines and medication adherence.

SETTING

The CONCARDPCI study conducted at seven large referral PCI centres in Norway and Denmark between June 2017 and May 2020.

PARTICIPANTS

A total of 3417 adults (78% men), using both generic and brand name medicines, with a mean age of 66 years (SD 11) who underwent PCI were followed up 2 and 6 months after discharge from hospital.

MAIN OUTCOME MEASURES

Perceptions of generic medicines were the main outcome. The secondary outcome was medication adherence.

RESULTS

Perceptions of generic medicines were significantly more negative at 2 than at 6 months (1.10, 95% CI 0.41 to 1.79, p=0.002). Female sex (-4.21, 95% CI -6.75 to -1.71, p=0.001), older age (-0.12, 95% CI -0.23 to -0.02, p=0.020), lower education level (overall p<0.001), ethnicity (overall p=0.002), Norwegian nationality (10.27, 95% CI 8.19 to 12.40, p<0.001) and reduced self-reported health status (0.19, 95% CI 0.09 to 0.41, p=0.003) were significantly associated with negative perceptions of generic medicines. There was no evidence to suggest that perceptions of generic medicines moderate the association between sociodemographic and clinical variables and medication adherence (p≥0.077 for all covariates). Moreover, self-reported medication adherence was high, with 99% scoring at or above the Medication Adherence Report Scale midpoint at both time points. There were no substantial correlations between negative perceptions of generic medicines and medication non-adherence at 2 months (r=0.041, 95% CI 0.002 to 0.081, p=0.037) or 6 months (r=0.038, 95% CI -0.005 to 0.081, p=0.057).

CONCLUSIONS

Mistrust and uncertainty about the safety and efficacy of generic medicines remains in a sizeable proportion of patients after PCI. This applies especially to those of lower socioeconomic status, older age, female sex, immigrants and those with poorer mental health. However, this study demonstrated a shift towards more positive perceptions of generic medicines in the longer term.

Predictors of Medication Adherence of Patients With Coronary Heart Disease After Percutaneous Coronary Intervention: A Structural Equation Modeling Based on the Extended Theory of Planned Behavior

BACKGROUND

The theory of planned behavior (TPB), combined with social support, forms the extended TPB, which has shown to predict adherence to health-related behavior effectively, but few studies have applied it to explain medication adherence in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).

OBJECTIVES

The aim of this study was to explore the factors associated with medication adherence and the underlying mechanisms based on the extended TPB among patients with CHD after PCI.

METHODS

A cross-sectional descriptive study was conducted among patients with CHD after PCI in 2 major hospitals in Guangzhou, China. Medication adherence was measured with the Medication Adherence Report Scale. Constructs of the TPB contributing to medication adherence were assessed by the Theory of Planned Behavior Questionnaire for Medication Adherence. Social support was measured by the Multidimensional Scale of Perceived Social Support. Structural equation modeling was used to examine the hypotheses based on the extended TPB.

RESULTS

A total of 300 patients were surveyed and 26.0% of them were nonadherent. The structural equation modeling had good fit indices and estimated 62.6% of the variance in medication adherence. Regarding the relationships between the extended TPB constructs and medication adherence, "intention" was directly associated with medication adherence, and "perceived behavioral control" positively predicted medication adherence directly and indirectly. "Affective attitude" and "subjective norm" were indirectly associated with medication adherence through "intention." Social support exerted an indirect effect on medication adherence through "subjective norm."

CONCLUSIONS

The extended TPB is an appropriate model to predict medication adherence and provides an effective framework for adherence-enhancing interventions.

MicroRNA-136-5p protects cardiomyocytes from coronary microembolization through the inhibition of pyroptosis

This study investigated how miR-136-5p partially affected cardiomyocyte pyroptosis in rats with coronary microembolization (CME). The cardiac function and structure of rats with CME were evaluated using echocardiography, hematoxylin and eosin staining, Masson staining, and troponin I level. Pyroptosis was induced by lipopolysaccharide (LPS) in isolated rat cardiomyocytes and evaluated by the expression of caspase-1, NOD-like receptor family pyrin domain-containing 3, interleukin-1β, and gasdermin D-N. After cell transfection, the expression of Ataxin-1 like (ATXN1L), pyrin domain-containing 1 (PYDC1), and pyroptosis-related proteins was assessed. Dual-luciferase reporter and immunoprecipitation assays were used to verify the relationships among miR-136-5p, ATXN1L, and capicua (CIC). MiR-136-5p was under-expressed, whereas ATXN1L was overexpressed in rats with CME and in LPS-treated primary cardiomyocytes. MiR-136-5p targeted ATXN1L, and ATXN1L bound to CIC to suppress PYDC1 expression. MiR-136-5p overexpression suppressed pyroptosis by inhibiting the binding of ATXN1L with CIC and promoting PYDC1 expression, which was reversed by simultaneous elevation of ATXN1L. In conclusion, miR-136-5p suppressed pyroptosis by upregulating PYDC1 via ATXN1L/CIC axis, thereby attenuating cardiac damage caused by CME.

Greater Nursing Role for Enhanced Post-Percutaneous Coronary Intervention Management

Percutaneous coronary intervention (PCI) has increasingly been used in management of coronary artery diseases (CAD). Coupled that with an increasing incidence rate of CAD has augmented the hospital burden with consequential post-PCI patient management problems and dissatisfaction. Nursing care has a key role to play in upgrading the healthcare services and raising patients’ satisfaction through enhanced patient education and engagement. In this regard, nursing-led intervention has shown some success in three main domains: risk reduction; psychological improvement; and quality of life. Urgent efforts are needed to formulize a structured follow-up with enhanced nursing role in post-PCI management to raise quality of healthcare.

Prevalence of pharmacological adherence in patients with coronary artery disease and associated factors

Objective:

to assess the prevalence of pharmacological adherence in patients with coronary artery disease and to identify factors associated with adherence.

Method:

a crosssectional, correlational study, including 198 patients with a previous diagnosis of coronary artery disease. Pharmacological adherence was assessed by the four-item Morisky Green test, and the factors that potentially interfere with adherence were considered independent variables. The association between the variables was determined by the Cox model, with a 5% significance level.

Results:

43% of the patients adhered to the treatment. Fatigue and palpitation, never having consumed alcohol and being served by medical insurance were associated with adherence. Lack of adherence was associated with considering the treatment complex, consumption of alcohol and being served by the public health care system. In the multiple analysis, the patients with fatigue and palpitations had a prevalence of adherence around three times higher and alcohol consumption was associated with a 2.88 times greater chance of non-adherence.

Conclusion:

more than half of the patients were classified as non-adherent. Interventions can be directed to some factors associated with lack of adherence.

Factors Contributing to Medication Adherence in Patients with a Chronic Condition: A Scoping Review of Qualitative Research

Introduction: Medication adherence continues to be a significant challenge in healthcare, and there is a shortage of effective interventions in this area. This scoping review studied the patient-related factors of medication adherence. Methods: We searched Medline Ovid, Scopus, and Cochrane Library from January 2009 to June 2021 to find the most recent original qualitative studies or systematic reviews that addressed the patient-related factors of medication adherence in treating chronic conditions. We used the PRISMA-ScR checklist to ensure the quality of the study. Results: The initial search revealed 4404 studies, of which we included 89 qualitative studies in the scoping review. We inductively organized the patient-related factors causing barriers, as well as the facilitators to medication adherence. The studies more often dealt with barriers than facilitators. We classified the factors as patient-specific, illness-specific, medication-related, healthcare and system-related, sociocultural, as well as logistical and financial factors. Information and knowledge of diseases and their treatment, communication, trust in patient-provider relationships, support, and adequate resources appeared to be the critical facilitators in medication adherence from the patient perspective. Discussion and conclusions: Patients are willing to discuss their concerns about medications. Better communication and better information on medicines appear to be among the critical factors for patients. The findings of this scoping review may help those who plan further interventions to improve medication adherence.

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.

Current trends in optimal medical therapy after PCI and its influence on clinical outcomes in China

Background

Limited data were available on the current trends in optimal medical therapy (OMT) after PCI and its influence on clinical outcomes in China. We aimed to evaluate the utilization and impact of OMT on the main adverse cardiovascular and cerebrovascular events (MACCEs) in post-PCI patients and analyzed the factors predictive of OMT after discharge.

Methods

We collected data from 3812 individuals from 2016.10 to 2017.09 at TEDA International Cardiovascular Hospital. They were classified into an OMT group and a non-OMT group according to their OMT status, which was defined as the combination of dual antiplatelet therapy, statins, β-blockers, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers after PCI. Multivariable Cox regression models were developed to assess the association between OMT and MACCEs, defined as all-cause mortality, nonfatal myocardial infarction, stroke, and target vessel revascularization. A logistic regression model was established to analyze the factors predictive of OMT.

Results

Our results revealed that the proportion of patients receiving OMT and its component drugs decreased over time. A total of 36.0% of patients were still adherent to OMT at the end of follow-up. Binary logistic regression analysis revealed that baseline OMT (P < 0.001, OR = 52.868) was the strongest predictor of OMT after PCI. The Cox hazard model suggested that smoking after PCI was associated with the 1-year risk of MACCE (P = 0.001, HR = 2.060, 95% CI 1.346–3.151), while OMT (P = 0.001, HR = 0.486, 95% CI 0.312–0.756) was an independent protective factor against postoperative MACCEs.

Conclusions

There was still a gap between OMT utilization after PCI and the recommendations in the evidence-based guidelines. Sociodemographic and clinical factors influence the application of OMT. The management of OMT and smoking cessation after PCI should be emphasized.

The transition from hospital to home following acute coronary syndrome: an exploratory qualitative study of patient perceptions and early experiences in two countries

OBJECTIVES

Following acute coronary syndrome (ACS), it is standard practice for stable patients to be discharged as quickly as possible from hospital. If patients are not adequately supported at this time, issues such as readmission can occur. We report findings from an exploratory qualitative study investigating the perceptions and early experiences of patients transitioning from hospitals in the UK and USA to home following ACS.

METHODS

Within 1 month of discharge, we conducted semi-structured telephone interviews with patients hospitalised for ACS (UK: n = 8; USA: n = 9). Data were analysed using the Framework Method.

KEY FINDINGS

We identified four superordinate themes. Coping, adjustment and management: Patients were still adjusting to the physical limitations caused by their event but most had begun to implement positive lifestyle changes. Gaps in care transition: Poor communication and organisation postdischarge resulted in delayed follow-up for some patients causing considerable frustration. Quality of care from hospital to home: Patients experienced varied inpatient care quality but had largely positive interactions in primary/community care. Pharmacy input during care transition was viewed favourably in both countries. Medication-taking beliefs and behaviour: Patients reported good initial adherence to treatment but side effects were a concern.

CONCLUSIONS

ACS patients experienced gaps in care early in the transition from hospital to home. Poor communication and uncoordinated support postdischarge negatively impacted patient experience. Further research is needed to determine how patients' early experiences following ACS can affect longer-term outcomes including healthcare engagement and treatment maintenance.

Patient and family perceptions and experiences of same-day discharge following percutaneous coronary intervention and those kept overnight

OBJECTIVE

To explore perceptions and experiences of patients discharged the same day (or not) and their family members towards same-day discharge following percutaneous coronary intervention.

DESIGN AND METHODS

A qualitative interpretative design. Semi-structured phone interviews were conducted with consented patients who underwent percutaneous coronary intervention, and their family members (n = 23). Data were analysed using a content analysis approach.

SETTING

This study was undertaken in the cardiac services department of an Australian tertiary hospital.

MAIN OUTCOME MEASURES

Perceptions and experiences of same-day discharge.

FINDINGS

A total of 31 patients and 23 family members were interviewed. Two categories emerged from the analysis: communication challenges with hospital staff and perceptions of same-day discharge. Family members were often not provided discharge instructions, and some same-day discharged patients felt vulnerable following discharge. When asked, most participants perceived same-day discharge as a preferred option because of its comfort and convenience. Some expressed uncertainty towards same-day discharge due to feeling anxious and apprehensive. Others misperceived same-day discharge as a signal that their heart problem was fixed without realising their underlying chronic health conditions.

CONCLUSION

Most patients and family members perceived same-day discharge as a preferred option. However, strategies are needed to support their transition from hospital to home, therefore, recognising and improving their long-term disease management.

Patient perspectives of nuisance bleeding and adherence to dual antiplatelet therapy: a qualitative study

OBJECTIVE

To understand the experiences of patients with dual antiplatelet therapy (DAPT) and nuisance bleeding, and their perspectives of the impact of nuisance bleeding on medication adherence and information seeking.

METHODS

We conducted focus groups with patients who had undergone percutaneous coronary intervention, coronary artery bypass graft and conservatively managed acute coronary syndrome patients. Two focus groups were with patients at the early stages of treatment (0-3 months), and two with patients coming to the end of treatment (9-12 months). Group discussions were audio recorded, and recordings were transcribed verbatim, anonymised and analysed using framework analysis.

FINDINGS

Nine patients taking DAPT for up to 3 months, and 12 taking DAPT between 9 and 12 months participated in the focus groups. We found that: (1) participants adhered to treatment when they believed DAPT was important to health outcomes; (2) those who experienced nuisance bleeding reported symptoms to be mild and manageable; (3) participants' and their family's understanding of DAPT risks and benefits, and their ability to manage symptoms, influenced perspectives of and experiences with adherence. Factors influencing DAPT knowledge included access to medication counselling, engaging with information communicated during medication counselling, and access to timely, relevant and expert information and advice after discharge from hospital.

CONCLUSIONS

Positive attitudes towards adherence were facilitated by knowledge and understanding of DAPT and confidence in dealing with symptoms caused by DAPT, but hindered by lack of opportunities to access relevant, timely and appropriate medication counselling. Education interventions should aim to support medication literacy through family-centred approaches and involve patients and families at all stages of intervention design and evaluation.

Nurse-led Motivational Telephone Follow-up After Same-day Percutaneous Coronary Intervention Reduces Readmission and Contacts to General Practice

BACKGROUND

Same-day discharge of patients undergoing percutaneous coronary intervention (PCI) may challenge preparation of patients for discharge.

OBJECTIVE

The objective of this study was to investigate whether nurse-led telephone follow-up influenced patients' self-management post-PCI.

METHODS

We performed a randomized study with an allocation rate of 1:1. A standardized nurse-led motivational telephone consultation was conducted between 2 and 5 days after PCI to support adherence to medical therapy, follow-up activities, emotional well-being, and healthy lifestyle. The control group received usual care and discharge procedures. Primary outcome was adherence to use of P2Y12 inhibitor (clopidogrel or ticagrelor) therapy at 30 days of follow-up.

RESULTS

We consecutively included 294 elective patients (83%) undergoing PCI and with planned same-day discharge. Adherence to P2Y12 inhibitors was not influenced by the intervention (intervention vs control, 95% vs 93%, respectively; P = .627). However, the proportion of patients readmitted (8% vs 16%, P = .048), as well as self-initiated contacts to general practitioners (29% vs 42%, P = .020), was lower in the intervention group compared with the control group. Patients in the intervention group were more likely to know how to manage symptoms of angina pectoris (90% vs 80%, P = .015), and a higher proportion of patients in the intervention group commenced healthy physical activities (53% vs 41%, P = .043).

CONCLUSION

Nurse-led motivational telephone follow-up did not influence adherence to antiplatelet medical therapy after PCI. However, the intervention positively influenced self-management of angina pectoris and reduced hospital readmissions and self-initiated contacts to general practitioners and hospitals.

Nurses' perceptions of patient participation in the myocardial infarction pathway

Aim

To explore nurses' perceptions of patient participation in different phases of the myocardial infarction pathway.

Design

Qualitative design with a hermeneutical approach.

Methods

Five focus groups were conducted at two hospitals, one with and one without percutaneous coronary intervention facilities, between February-November 2018. Participants were recruited through purposive sampling. Twenty-two nurses experienced in cardiac care participated. The analysis had a hermeneutical approach.

Results

The findings revealed nurses' perceptions of patient participation in different phases of the myocardial infarction pathway. Four themes were identified: (a) variation between paternalism and autonomy in the acute phase; (b) individualization of dialogue and patient participation during treatment; (c) lack of coherence in the pathway hinders patient participation at discharge; and (d) cardiac rehabilitation promotes patients' autonomous decisions in lifestyle changes.

Level of Medication Adherence and Its Associated Factors among Patients Receiving Antiretroviral Therapy at a Tertiary Care Hospital in South India

Introduction: Anti-retro viral drugs are the corner stone of management of human immunodeficiency virus (HIV) infection. Anti-retro viral drugs have been consistently proven to reduce mortality due to HIV. The aim of this study was to identify the level of drug adherence and related challenges for adherence.

Methods: A cross- sectional study was conducted in the antiretroviral therapy (ART) clinic of a tertiary care teaching hospital. Patients who were above 18 years of age, on ART for at least six months and underwent counselling before starting ART were included in the study (n = 143). Demographic variables and clinical profile were noted and level of drug adherence and associated factors were assessed using Morisky Green Levine test and check list respectively. Data was analysed in SPSS version 22.

Results: Most of the study subjects (89.5%) had high level of medication adherence and 10.5% had medium level adherence. Factors contributing to high adherence level were confidentiality and trust among health workers, concerned about their own health, understanding about the prescribed drugs, idea about disease progression, effectiveness and knowledge of anti-retro viral drugs.

Conclusion: Drug adherence was found to be high among HIV- infected patients in this study and various reasons contributed for the high adherence among the study subjects.

Prescribing and medical non-adherence after myocardial infarction: qualitative interviews with general practitioners in Germany

BACKGROUND

An increasing prevalence of having survived a myocardial infarction increases the importance of medical secondary prevention. Although preventive medication reduces mortality, prescribing and adherence are known to be frequently insufficient. General practitioners are the most important prescriber. However, their perspective on prescribing and medical non-adherence following myocardial infarction has not yet been explored. Thus, the aim of this study was to explore the general practitioners' perspective on long-term care after myocardial infarction focussing on medical prevention.

METHODS

In this qualitative interview study we conducted episodic interviews with sixteen general practitioners from rural and urban surgeries in Germany. Framework analysis with focus on general practitioners' prescribing and patients' non-adherence was performed.

RESULTS

Almost all general practitioners reported following guidelines for myocardial infarction aftercare and prescribing the medication that was initiated in the hospital; however, they described deviating from guidelines because of drugs' side effects or patients' intolerances. Some questioned the benefits of medical secondary prevention for the oldest of patients. General practitioners perceived good adherence among their patients who had had an MI while they regarded their methods for assessing medical non-adherence as limited. They perceived diverse reasons for non-adherence, particularly side effects, patients' freedom from symptoms and patients' indifference to health. They attributed mainly negative characteristics, like lack of knowledge and understanding, to non-adherent patients. These characteristics contribute to the difficulty of convincing these patients to take medications as prescribed. General practitioners improved adherence by preventing side effects, explaining the medication's necessity, facilitating intake and involving patients in decision-making. However, about half of the general practitioners reported threatening their patients with negative consequences of non-adherence.

CONCLUSIONS

General practitioners should be aware that discharge medication can be insufficient and thus, should always check hospital recommendations for accordance with guideline recommendations. Improving physicians' communication skills and informing and motivating patients in an adequate manner, for example in simple language, should be an important goal in the hospital and the general practitioner setting. General practitioners should assess patients' motivations through motivational interviewing, which no general practitioner mentioned during the interviews, and talk with them about adherence and long-term treatment goals regularly.

Trivial or Troublesome: Experience with Coronary Heart Disease Medication from the Patient's Perspective

BACKGROUND

Living with coronary heart disease (CHD) usually means being prescribed several medications to help prevent new cardiac events. Using medicines for long-term conditions impacts on day-to-day life, and coping with medicines can be burdensome and can affect the quality of life. To enable better support of these patients, we need to understand their collective medicine-related experience.

PURPOSE

The purpose of this study was to describe patients' medicine-related experience 1 year after the diagnosis of CHD.

PATIENTS AND METHODS

A qualitative, descriptive study using semi-structured interviews was conducted in 19 patients in their homes or at Linnaeus University, Sweden. Interviews were recorded and transcribed verbatim. Qualitative content analysis with an inductive approach was used.

RESULTS

Patients' experiences with using their medicines after diagnosis of CHD differed considerably. Some patients found handling the medicines and administering their treatment very easy, natural and straightforward, while others found that it was distressing or troublesome, and influenced their lives extensively. There was a varied sense of personal responsibility about the treatment and use of medicines. The patients' experiences were classified into one of seven categories: a sense of security, unproblematic, learning to live with it, taking responsibility for it, somewhat uncertain, troublesome, or distressing. Participants in the study who expressed an unproblematic view of medicine taking also often revealed that they had dilemmas or uncertainties.

CONCLUSION

Patients' medicine-related experiences after CHD vary greatly. The findings of this study highlight a need for more individualized support for patients using medicines for secondary prevention. The patients often needed better dialogue with healthcare providers to optimally manage their medicines. Medicine-related support for these patients should encompass various aspects of medicine-taking.

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.

Patient Perspectives on Factors Influencing Medication Adherence Among People with Coronary Heart Disease (CHD) and CHD Risk Factors

BACKGROUND

Few qualitative studies have explored factors influencing medication adherence among people with coronary heart disease (CHD) or CHD risk factors. We explored how factors related to the patient (e.g. self-efficacy), social/economic conditions (e.g. social support and cost of medications), therapy (e.g. side effects), health condition (e.g. comorbidities), and the healthcare system/healthcare team (e.g. support from healthcare providers and pharmacy access) influence medication adherence, based on the World Health Organization Multidimensional Adherence Model (WHO-MAM).

METHODS

We conducted 18 in-depth qualitative interviews from April to July 2018 with ambulatory care patients aged ≥45 years (8 black men, 5 black women, 2 white men, and 3 white women) who were using medications for diabetes, hypertension, dyslipidemia and/or CHD. We used thematic analysis to analyze the data, and sub-themes emerged within each WHO-MAM dimension.

FINDINGS

Patient-related factors included beliefs about medications as important for self and faith; the desire to follow the advice of family, friends, and influential others; and self-efficacy. Social/economic factors included observations of social network members and information received from them; social support for medication adherence and pharmacy utilization; and economic influences. Therapy-related barriers included side effects and medicine schedules. Only a few participants mentioned condition-related factors. Healthcare system/healthcare team-related factors included support from doctors and pharmacists; and ease of pharmacy access and utilization.

CONCLUSION

These results underscore the need for multidimensional interventions aimed at improving medication adherence and overall health of patients with CHD and CHD risk factors.
