Medication Adherence of Older Adults with Hypertension: A Systematic Review.

Objective: Hypertension (HTN) significantly increases the risk of stroke and heart disease, which are the leading causes of death and disability globally, particularly among older adults. Antihypertensive medication is a proven treatment for blood pressure control and preventing complications. However, medication adherence rates in older adults with HTN are low. In this review, we systematically identified factors influencing medication adherence in older adults with HTN. Methods: We applied the PRISMA guidelines and conducted systematic searches on PubMed, MEDLINE, and Google Scholar in July 2022 to identify preliminary studies reporting factors influencing medication adherence among older adults with HTN. The convergent integrated analysis framework suggested by the Joanna Briggs Institute for systematic reviews was adopted for data synthesis. Results: Initially, 448 articles were identified, and after title and abstract screening, 16 articles qualified for full-text review. During this phase, three articles were excluded for reporting on irrelevant populations or focusing on issues beyond the review's aim, leaving thirteen studies in the final review. After data synthesis, fifteen themes were extracted from the key findings of the included studies. The most prevalent themes included the number of medications used (53.9%, n=7 studies), financial status (38.5%, n=5), sex (38.5%, n=5), age (30.1%, n=4), duration of disease (23.1%, n=3), comorbidities (23.1%, n=3), and health compliance (23.1%, n=3). Other themes, such as education, health literacy, health belief, medication belief, perception of illness, patient-physician relationship, self-efficacy, and social support, were also identified. Conclusion: The findings of this review highlight critical areas for developing innovative, evidence-based programs to improve medication adherence in hypertensive older adults. Insights from this review can contribute to improving medication adherence and preventing future health complications.

Palliative Care Education in Cardiovascular Disease Fellowships: A National Survey of Program Directors.

BACKGROUND: Palliative care (PC) is an essential component of high-quality care for people with cardiovascular disease (CVD). However, little is known about the current state of PC education in CVD training, including attitudes toward integration of PC into training and implementation of PC by the program's leadership. METHODS: We developed a nationwide, cross-sectional survey that queried education approaches, perspectives and barriers to PC education in general CVD fellowship training. The survey was distributed to 392 members of the American College of Cardiology Program Director (PD) listserv, representing 290 general CVD fellowships between 1/2023 and 4/2023. We performed descriptive and ꭕ2 analyses of survey data. RESULTS: Of the program's representatives, 56 completed the survey (response rate = 19.3%). Respondents identified themselves as current PDs (89%), associate PDs (8.9%) or former PDs (1.8%), representing a diverse range of program sizes and types and regions of the country. Respondents reported the use of informal bedside teaching (88%), formal didactics (59%), online or self-paced modules (13%), in-person simulation (11%), and clinical rotations (16%) to teach PC content. Most programs covered PC topics at least annually, although there was variability by topic. We found no associations between program demographics and type or frequency of PC education. Most respondents reported dissatisfaction with the quantity (62%) or quality (59%) of the PC education provided. Barriers to PC education included an overabundance of other content to cover (36%) and perceived lack of fellow (20%) or faculty (18%) interest. Comments demonstrated the importance of PC education in fellowship, the lack of a requirement to provide PC education, difficulty in covering all topics, and suggestions of how PC skills should be taught. CONCLUSIONS: In a national survey of CVD educational leadership concerning approaches to PC education in CVD training, respondents highlighted both challenges to implementation of formal PC curricula in cardiology training and opportunities for comprehensive PC education.

Effectiveness of Medical Student Counseling for Hospitalized Patients Addicted to Tobacco (MS-CHAT): a Randomized Controlled Trial.

BACKGROUND: Low-middle-income countries face an enormous burden of tobacco-related illnesses. Counseling for tobacco cessation increases the chance of achieving quit outcomes, yet it remains underutilized in healthcare settings. OBJECTIVE: We tested the hypothesis that utilizing trained medical students to counsel hospitalized patients who use tobacco will lead to an increase in patient quit rates, while also improving medical student knowledge regarding smoking cessation counseling. DESIGN: Investigator-initiated, two-armed, multicenter randomized controlled trial conducted in three medical schools in India. PARTICIPANTS: Eligibility criteria included age 18-70 years, active admission to the hospital, and current smoking. INTERVENTION: A medical student-guided smoking cessation program, initiated in hospitalized patients and continued for 2 months after discharge. MAIN MEASURES: The primary outcome was self-reported 7-day point prevalence of smoking cessation at 6 months. Changes in medical student knowledge were assessed using a pre- and post-questionnaire delivered prior to and 12 months after training. KEY RESULTS: Among 688 patients randomized across three medical schools, 343 were assigned to the intervention group and 345 to the control group. After 6 months of follow up, the primary outcome occurred in 188 patients (54.8%) in the intervention group, and 145 patients (42.0%) in the control group (absolute difference, 12.8%; relative risk, 1.67; 95% confidence interval, 1.24-2.26; p < 0.001). Among 70 medical students for whom data was available, knowledge increased from a mean score of 14.8 (± 0.8) (out of a maximum score of 25) at baseline to a score of 18.1 (± 0.8) at 12 months, an absolute mean difference of 3.3 (95% CI, 2.3-4.3; p < 0.001). CONCLUSIONS: Medical students can be trained to effectively provide smoking cessation counseling to hospitalized patients. Incorporating this program into the medical curriculum can provide experiential training to medical students while improving patient quit rates. TRIAL REGISTRATION: URL: http://www.

Cardiovascular services in Covid-19 - Impact of the pandemic and lessons learned.

The coronavirus disease 2019 (COVID-19) pandemic immediately and perhaps irrevocably impacted society at large, the provision of cardiovascular (CV) care, the function and staffing of hospitals, and CV clinicians. Initially many clinicians at all career stages rose to the challenges, and support and accolades were the initial societal response. Politicization of the public health response as well as widespread misinformation and disinformation all negatively impacted CV clinicians' roles as well diminished and, in some cases, eliminated their public and self-esteem. Unabated stress, disrespect, and a likely lack of emotional and physical respite may all have contributed to the Great Resignation. Insights gained from review of the COVID-19 pandemic may help inform changes to foster system resiliency and prepare for an improved response to the inevitable next stressor.

Outcomes of coronary artery bypass grafting in patients with heart failure with a midrange ejection fraction.

BACKGROUND: Coronary artery bypass grafting (CABG) improves survival in patients with heart failure and severely reduced left ventricular systolic function (LVEF). Limited data exist regarding adverse cardiovascular event rates after CABG in patients with heart failure with midrange ejection fraction (HFmrEF; LVEF > 40% and < 55%). METHODS: We analyzed data on isolated CABG patients from the Veterans Affairs national database (2010-2019). We stratified patients into control (normal LVEF and no heart failure), HFmrEF, and heart failure with reduced LVEF (HFrEF) groups. We compared all-cause mortality and heart failure hospitalization rates between groups with a Cox model and recurrent events analysis, respectively. RESULTS: In 6533 veterans, HFmrEF and HFrEF was present in 1715 (26.3%) and 566 (8.6%) respectively; the control group had 4252 (65.1%) patients. HFrEF patients were more likely to have diabetes mellitus (59%), insulin therapy (36%), and previous myocardial infarction (31%). Anemia was more prevalent in patients with HFrEF (49%) as was a lower serum albumin (mean, 3.6 mg/dL). Compared with the control group, a higher risk of death was observed in the HFmrEF (hazard ratio [HR], 1.3 [1.2-1.5)] and HFrEF (HR, 1.5 [1.2-1.7]) groups. HFmrEF patients had the higher risk of myocardial infarction (subdistribution HR, 1.2 [1-1.6]; P = .04). Risk of heart failure hospitalization was higher in patients with HFmrEF (HR, 4.1 [3.5-4.7]) and patients with HFrEF (HR, 7.2 [6.2-8.5]). CONCLUSIONS: Heart failure with midrange ejection fraction negatively affects survival after CABG. These patients also experience higher rates myocardial infarction and heart failure hospitalization.

Meta-Analysis of Antidepressant Pharmacotherapy in Patients Eligible for Cardiac Rehabilitation: ANTIDEPRESSANT AMBIVALENCE.

PURPOSE: Many patients exhibit clinically significant depression upon enrollment in cardiac rehabilitation (CR). Antidepressants are a first-line treatment option for depression, but the effectiveness of antidepressants in patients with heart disease is mixed. The purpose of this meta-analysis was to evaluate the efficacy of antidepressants for depression in patients eligible for CR. METHODS: A meta-analysis was conducted including randomized controlled trials of antidepressants from January 1990 to September 2021 that compared antidepressants with placebo. Random-effects models were used between group effect sizes (Hedges' g ). RESULTS: A total of 13 trials with predominately White (68% ± 12; n =7) male (70% ± 11) samples averaging 61 ± 5 yr compared antidepressants (1128 participants) with placebo (1079 participants). Antidepressants reduced depressive symptoms ( g = 0.17: 95% CI, 0.08-0.27), but the effect was small. Heterogeneity among study effects was low ( I2 = 6.42) and nonsignificant ( Q = 10.75, P = .46), although patients with heart failure ( gHF = 0.05: 95% CI, -0.09 to 0.18) demonstrated smaller effects compared with patients with other cardiovascular disease conditions (g non-HF = 0.22: 95% CI, 0.11-0.32) ( QB [1] = 3.97; P < .05). No study reported safety concerns associated with antidepressants. SUMMARY: The effect size of antidepressant pharmacotherapy in this population is small. No trials reported on the combined effects of exercise and pharmacotherapy. If the patient is not suicidal, CR staff may consider patient preference and refer patients for additional treatment as necessary.

Revascularization in ischaemic heart failure with preserved ejection fraction: a nationwide cohort study.

AIMS: Despite the common occurrence of coronary artery disease (CAD) and heart failure (HF) with preserved ejection fraction (HFpEF), there is limited evidence to guide revascularization. METHODS AND RESULTS: We investigated the long-term outcomes of coronary artery bypass grafting (CABG) in patients with HF and significant CAD across the spectrum of ejection fraction, using a large national cohort of patients from the Veteran Affairs (VA) Medical Centers in the US. Patients with HF were stratified into groups, HFpEF, HF with mid-range ejection fraction (HFmrEF), and HF with reduced ejection fraction (HFrEF) and compared to patients with no preoperative HF. We analysed 10 396 patients. Despite an increased hazard in the first year following revascularization, the long-term survival (median follow-up 6.6 years; interquartile range 3.7-10.1) of HFpEF post-CABG was similar to controls (hazard ratio 0.85, 95% confidence interval 0.68-1.06), but survival progressively declined with HFmrEF and HFrEF. Similar trends were seen with recurrent HF hospitalization with lower risk with baseline HFpEF (43.9 ± 6.9/100 patient-years) compared to HFmrEF (65.9 ± 3.8/100 patient-years) and HFrEF (93.4 ± 4.8/100 patient-years). Although HFpEF patients had lower mortality and HF hospitalization post-CABG compared to patients with a lower ejection fraction, they experienced the highest rates of future myocardial infarction. CONCLUSION: Although HFpEF patients with CAD have greater short-term risk post-CABG, their long-term survival is comparable to controls. However, they are at increased risk for HF hospitalizations and myocardial infarction. These data support the safety of CABG in HFpEF patients and suggest continuum of mortality risk for ischaemic HF when stratified by baseline ejection fraction before revascularization.

Health Literacy, Cognitive Function, and Mortality in Patients With Heart Failure.

BACKGROUND: Health literacy has predicted mortality in heart failure. However, the role of cognitive functioning in this relationship has not been evaluated. We hypothesized that health literacy would predict all-cause mortality but that cognitive functioning would modify the relationship between health literacy and mortality in heart failure. OBJECTIVE: The aim of this study was to examine the association between health literacy, cognitive functioning, and mortality in patients with heart failure. METHODS: This secondary analysis of a larger study included 298 patients with heart failure with reduced ejection fraction (trial identifier: NCT01461629). Health literacy was evaluated using the Rapid Estimate of Adult Literacy in Medicine (REALM) and Medical Term Recognition Test (METER), and cognitive functioning was evaluated using the Modified Mini-Mental Status Examination (3MS). Cox proportional hazards regression was used with time-until-death as the dependent variable. RESULTS: After controlling for age, sex, and race, neither METER nor REALM scores predicted mortality in heart failure (Ps ≥ .37). However, 3MS predicted mortality in models using the METER (Δχ2 = 9.20, P < .01; B = -.07; hazard ratio, 0.94 [95% confidence interval, 0.89-0.98]; P < .01) and REALM (Δχ2 = 9.77, P < .01; B = -0.07; hazard ratio, 0.94 [95% confidence interval, 0.90-0.97]; P < .01). Furthermore, adding the 3MS improved model fit. CONCLUSIONS: Cognitive functioning predicted mortality in heart failure better than health literacy. Results suggest the need to further evaluate the contribution of cognitive functioning to increased risk of mortality in those with heart failure.

Cardiac rehabilitation in heart failure: Indications for exercise training based on heart failure phenotype.

Exercise intolerance with dyspnea and fatigue is pervasive amongst individuals with heart failure (HF) due to both central and peripheral mechanisms. Cardiac rehabilitation (CR) is a cornerstone therapy for numerous cardiovascular disease (CVD) processes, and it's use in HF with reduced ejection fraction (HFrEF) has shown significant benefit in improved mortality and quality of life (QoL). Less is known about the benefit of CR in the setting of HF with preserved ejection fraction (HFpEF), and optimal exercise therapy (ET) may vary based on underlying disease phenotype. Here we offer review of existing data for ET in both HFrEF and HFpEF with proposed exercise treatment modalities based on underlying comorbidities and variable phenotypes.

Diaphragmatic pacemaker-induced ventricular tachycardia leading to cardiac arrest: a case report.

BACKGROUND: Diaphragmatic pacemakers are used to assist respiration in ventilator-dependent patients. Electromagnetic interference with intrinsic cardiac electrical activity is a theoretical risk but has never been reported in the literature. This case highlights a serious complication of cardiac arrest as a result of diaphragmatic pacing. CASE SUMMARY: We report a quadriplegic patient with recent diaphragmatic pacemaker implantation who presented with ventricular tachycardia leading to cardiac arrest. Extensive workup was negative for other aetiologies for ventricular arrhythmias. Reduction of the left-sided diaphragmatic pacemaker voltage resulted in cessation of ventricular ectopy. DISCUSSION: Diaphragmatic pacing at high voltages can cause unwanted transmission of impulses to the cardiac myocytes as a rare complication. This should be noted as a possible complication of intramuscular diaphragmatic pacing, and efforts should be taken to circumvent this risk in the future.

A pilot randomized clinical trial of a teamwork intervention for heart failure care dyads.

BACKGROUND: Dyadic heart failure (HF) management can improve outcomes for patients and caregivers and can be enhanced through eHealth interventions. OBJECTIVE: To evaluate the feasibility, acceptability, and preliminary efficacy of an eHealth dyadic teamwork intervention, compared to an attention control condition. METHODS: We recruited 29 HF patient-caregiver dyads from inpatient units and randomized dyads to an intervention or a control group. We calculated enrollment and retention rates, described acceptability using interview and questionnaire data, and computed intervention effect sizes. RESULTS: 37% of eligible dyads agreed to participate and 93% of randomized participants completed follow-up questionnaires. Participants found both study conditions to be acceptable. Between-group effect sizes suggested that the intervention led to improvements in relationship quality, self-efficacy, and quality of life for patients and caregivers. CONCLUSIONS: Dyadic recruitment from acute care settings is challenging. Findings provide initial evidence that our intervention can contribute to better health outcomes for HF dyads.

Insights from Monitoring Aspirin Adherence: A Medication Adherence Cascade Tool.

BACKGROUND: Adherence to recommended medications is a key issue in the care of patients with cardiovascular disease (CVD) and barriers to adherence are well established during the medication adherence cascade, the processes of prescribing, obtaining, taking, and maintaining medication use. Aspirin avoids many of the barriers in the medication adherence cascade as it does not require a prescription (prescribing) and is inexpensive, easily accessible (obtaining), prescribed once-daily (taking) as an over-the-counter medication and is generally perceived by patients as safe (maintaining). The purpose of this paper is to report aspirin adherence and propose the Medication Adherence Cascade Tool to assist clinicians to consider all aspects of medication adherence. METHODS: Adherence to aspirin was monitored with an electronic pillbox. Frequency analysis, independent T-tests, and ANOVA were completed on 151 patients with underlying heart failure who were prescribed aspirin within a larger parent study. Chi-square tests were completed to assess differences in baseline demographic characteristics. FINDINGS: Mean aspirin adherence was 82.2% overall, with 11.9% of sample with adherence 50%, 18.5% with adherence 50-80%, and 69.5% with adherence ≥80%. Greater adherence was observed in self-identified White as compared to Black patients (84.47% vs 73.53%; p = 0.014), and patients ≥70 years of age compared to <70 years (87.00% vs 77.49%; p = 0.009). INTERPRETATION: Aspirin adherence was suboptimal despite the fact that it addresses most of the barriers on the medication adherence cascade (ie, relatively easy access, low cost, and low risk). A Medication Adherence Cascade Tool (MACT) is proposed as a clinical guide to facilitate patient-provider co-production of strategies to address medication adherence. The tool can assist patients and providers to co-produce adherence to achieve optimal medication benefits.

Rationale and Design of a Randomized Controlled Trial to Evaluate the Effectiveness of Medical Student Counseling for Hospitalized Patients Addicted to Tobacco (the MS-CHAT Trial).

Globally, India is the second largest consumer of tobacco. However, Indian medical students do not receive adequate training in smoking cessation counseling. Each patient hospitalization is an opportunity to counsel smokers. Medical Student Counseling for Hospitalized patients Addicted to Tobacco (MS-CHAT) is a 2-arm multicenter randomized controlled trial (RCT) that compares the effectiveness of a medical student-guided smoking cessation program initiated in inpatients and continued for two months after discharge versus standard hospital practice. Current smokers admitted to the hospital are randomized to receive either usual care or the intervention. The intervention group receives inpatient counseling and longitudinal postdischarge telephone follow-up by medical students. The control group receives counseling at the discretion of the treating physician. The primary outcome is biochemically verified 7-day point prevalence of smoking cessation at 6 months after enrollment. Changes in medical student knowledge and attitude will also be studied using a pre- and postquestionnaire delivered prior to and 12 months after training. This trial tests a unique model that seeks to provide hands-on experience in smoking cessation counseling to medical students while simultaneously improving cessation outcomes among hospitalized smokers in India.
