(Wolters Kluwer, 2022-09) Jung, Miyeon; Hays, Laura M.; Pang, Peter S.; Newhouse, Robin P.; Arkins, Thomas P.; O'Donnell, Daniel; Cook, Ryan; Gradus-Pizlo, Irmina; McAdams, Ellen; Pressler, Susan J.; School of Nursing
Background Heart failure (HF) is a common condition leading to activation of emergency medical services (EMS). Objective The aim of this study was to describe reasons given by persons with HF, family members, or other caregivers for requesting EMS activation during 911 calls. Methods In this descriptive qualitative study, a content analysis was performed on transcribed audio files of 383 EMS requests involving 383 persons with HF in the community. Results One hundred forty-seven calls (38.4%) were placed by the family members, 75 (19.6%) were placed by the patients, 56 (14.6%) were placed by healthcare workers or personnel from living facilities, and the remaining calls (n = 105, 27.4%) were placed by others (eg, friends, neighbors, officers). Three broad categories of symptoms, signs, and events were identified as the reasons for an EMS request. Frequently reported symptoms were breathing problems (55.4%), chest pain (18.3%), and other pain (eg, head, extremities) (16.7%). Signs included decreased consciousness (15.4%), swelling (5.7%), and bleeding (5.0%). The reported events involved falls (8.1%), heart attack (6.3%), hypoxic episodes (6.0%), stroke (5.2%), and post–hospital-discharge complications (4.7%). In most calls (74.9%), multiple reasons were reported and a combination of symptoms, signs, and events were identified. Heart failure diagnosis was mentioned in fewer than 10% of the calls. Conclusions Overall, symptoms and signs of HF exacerbation were common reasons to activate 911 calls. Falls were frequently reported. Under the duress of the emergent situations surrounding the 911 call, callers rarely mentioned the existence of HF. Interventions are needed to guide patients with HF and their family members to promote the management of HF to reduce EMS activation as well as to activate EMS quickly for acute changes in HF conditions.

(Wolters Kluwer, 2024) Jung, Miyeon; Apostolova, Liana G.; Gao, Sujuan; Burney, Heather N.; Lai, Dongbing; Saykin, Andrew J.; Pressler, Susan J.; School of Nursing
Background: Incidence of cognitive impairment and its consequences have not been fully examined in heart failure (HF). Objective: The aim of this study was to examine associations of HF with cognitive decline, frequencies and risks of, and time-to-develop mild cognitive impairment (MCI) or dementia during 15-year follow-up. Methods: For this retrospective cohort study, data were retrieved from the National Alzheimer's Coordinating Center. Cognitive decline was assessed using the Uniform Data Set neuropsychological battery. Development of MCI and dementia was assessed using clinically diagnosed cognitive status. Results: Compared with participants without HF (n = 12 904), participants with HF (n = 256) had more decline in attention, executive function, and memory while controlling for covariates including apolipoprotein E4. Participants with HF developed MCI or dementia more frequently (44.9% vs 34.4%), developed dementia faster from normal cognition, and had a lower risk of dementia from MCI after controlling for covariates (hazard ratio, 0.71) than participants without HF. Conclusions: Heart failure was associated with accelerated cognitive decline.
Characterizing pain leading to emergency medical services activation in heart failure
(Wolters Kluwer, 2022) Smith, Asa B.; Jung, Miyeon; Lee, Christopher; Pressler, Susan J.; School of Nursing
Background: Pain is a common but understudied symptom among patients with heart failure (HF) transported by emergency medical services (EMS). The aims were to determine explanatory factors of a primary complaint of pain and pain severity, and characterize pain among patients with HF transported by EMS. Methods: Data from electronic health records of patients with HF transported by EMS within a midwestern United States county from 2009 to 2017 were analyzed. Descriptive statistics, χ 2 , analysis of variance, and logistic and multiple linear regression analyses were used. Results: The sample (N = 4663) was predominantly women (58.1%) with self-reported race as Black (57.7%). The mean age was 64.2 ± 14.3 years. Pain was the primary complaint in 22.2% of the sample, with an average pain score of 6.8 ± 3.1 out of 10. The most common pain complaint was chest pain (68.1%). Factors associated with a primary pain complaint were younger age (odds ratio [OR], 0.97; 95% confidence interval [CI], 0.96-0.97), history of myocardial infarction (OR, 1.96; 95% CI, 1.55-2.49), and absence of shortness of breath (OR, 0.67; 95% CI, 0.58-0.77). Factors associated with higher pain severity were younger age ( b = -0.05, SE = 0.013), being a woman ( b = 1.17, SE = 0.357), and White race ( b = -1.11, SE = 0.349). Conclusions: Clinical and demographic factors need consideration in understanding pain in HF during EMS transport. Additional research is needed to examine these factors to improve pain management and reduce transports due to pain.

Computerized Cognitive Training and 24-Month Mortality in Heart Failure
(Wolters Kluwer, 2024) Jung, Miyeon; Smith, Asa B.; Giordani, Bruno; Clark, David G.; Gradus-Pizlo, Irmina; Wierenga, Kelly L.; Lake, Kittie Reid; Pressler, Susan J.; School of Nursing
Background: Cognitive dysfunction predicts mortality in heart failure (HF). Computerized cognitive training (CCT) has shown preliminary efficacy in improving cognitive function. However, the relationship between CCT and mortality is unclear. Aims were to evaluate (1) long-term efficacy of CCT in reducing 24-month mortality and (2) age, HF severity, global cognition, memory, working memory, depressive symptoms, and health-related quality of life as predictors of 24-month mortality among patients with HF. Methods: In this prospective longitudinal study, 142 patients enrolled in a 3-arm randomized controlled trial were followed for 24 months. Logistic regression was used to achieve the aims. Results: Across 24 months, 16 patients died (CCT, 8.3%; control groups, 12.8%). Computerized cognitive training did not predict 24-month mortality (odds ratio [OR], 0.65). Older age (OR, 1.08), worse global cognition (OR, 0.73), memory (OR, 0.81), and depressive symptoms (OR, 1.10) at baseline predicted 24-month mortality. Conclusions: Efficacious interventions are needed to improve global cognition, memory, and depressive symptoms and reduce mortality in HF.
Construct Validity of the Multi-Source Interference Task to Examine Attention in Heart Failure
(Wolters Kluwer, 2018-11) Jung, Miyeon; Jonides, John; Berman, Marc G.; Northouse, Laurel; Koelling, Todd M.; Pressler, Susan J.; School of Nursing
Background Patients with heart failure (HF) are at risk of cognitive dysfunction, including decreased directed attention. Directed attention is critical for performing daily activities including HF self-care by facilitating one to follow instructions or train-of-thought when there are interferences in which presented stimuli are in conflict with one another. The Multi-Source Interference Task (MSIT) is a computerized neuropsychological test that examines the function of the dorsal anterior cingulate cortex, the neurological substrate for directed attention. However, the MSIT has not been used in past HF studies. Objective The purpose of the study was to examine construct validity of the MSIT in HF. Methods Baseline data were obtained from a cognitive intervention study among patients with HF (n = 22) and age- and education-matched healthy adults (n = 20). Construct validity was evaluated using t tests to examine differences between patients with HF and healthy adults and congruent and incongruent MSIT trials. Pearson’s correlations were computed to examine relationships between the MSIT and Trail-Making Test, Stroop Test, and Attentional Function Index. Results Compared with healthy adults, patients with HF demonstrated worse performance (i.e., slower response times and higher error rates) on MSIT. Patients with HF had worse performance on MSIT incongruent trials than congruent trials. Interference z scores of MSIT did not correlate with Trail-Making Tests A and B and Stroop Test interference z scores, but the MSIT interference z scores correlated with perceived attention function measured by Attentional Function Index. Discussion Construct validity of the MSIT was supported, in part, among patients with HF. The MSIT is a sensitive measure of detecting worse directed attention among patients with HF compared with healthy adults. The preliminary findings support the use of the MSIT as a measure of directed attention in HF. Confirmation is warranted for current findings in larger samples.
Design and Rationale of the Cognitive Intervention to Improve Memory in Heart Failure Patients Study
(Wolters Kluwer, 2018-07) Pressler, Susan J.; Giordani, Bruno; Titler, Marita; Gradus-Pizlo, Irmina; Smith, Dean; Dorsey, Susan G.; Gao, Sujuan; Jung, Miyeon; School of Nursing
BACKGROUND: Memory loss is an independent predictor of mortality among heart failure patients. Twenty-three percent to 50% of heart failure patients have comorbid memory loss, but few interventions are available to treat the memory loss. The aims of this 3-arm randomized controlled trial were to (1) evaluate efficacy of computerized cognitive training intervention using BrainHQ to improve primary outcomes of memory and serum brain-derived neurotrophic factor levels and secondary outcomes of working memory, instrumental activities of daily living, and health-related quality of life among heart failure patients; (2) evaluate incremental cost-effectiveness of BrainHQ; and (3) examine depressive symptoms and genomic moderators of BrainHQ effect. METHODS: A sample of 264 heart failure patients within 4 equal-sized blocks (normal/low baseline cognitive function and gender) will be randomly assigned to (1) BrainHQ, (2) active control computer-based crossword puzzles, and (3) usual care control groups. BrainHQ is an 8-week, 40-hour program individualized to each patient's performance. Data collection will be completed at baseline and at 10 weeks and 4 and 8 months. Descriptive statistics, mixed model analyses, and cost-utility analysis using intent-to-treat approach will be computed. CONCLUSIONS: This research will provide new knowledge about the efficacy of BrainHQ to improve memory and increase serum brain-derived neurotrophic factor levels in heart failure. If efficacious, the intervention will provide a new therapeutic approach that is easy to disseminate to treat a serious comorbid condition of heart failure.

Differential Gene Expression Among Patients With Heart Failure Experiencing Pain
(Wolters kluwer Health, 2023-02-26) Smith, Asa; Jung, Miyeon; Pressler, Susan; Mocci, Evelina; Dorsey, Susan
Background: Chronic pain is frequently experienced by patients with heart failure (HF) and is associated with higher mortality, higher symptom burden, and worsened health-related quality of life. However, the genomic mechanisms underlying chronic pain in HF are understudied. Building an understanding of the mechanistic underpinnings of pain may inform novel interventions. Objective: The objective was to identify genes associated with pain from mRNA sequence data collected from patients with HF with and without pain. Methods: The current study analyzed data from 40 patients with HF previously enrolled in a clinical trial. Pain presence was measured using the Health Utilities Index Mark-3. Genes were tested for differential expression using DESeq2, and differentially expressed genes were analyzed for protein–protein interaction (PPI) and relevant ontological pathways using Metascape. Genes located within the core of the PPI network were considered key in disease-relevant biological pathways. Differentially expressed genes within this PPI network were reviewed in existing literature to narrow down candidate genes of interest. These target genes of interest were reanalyzed in a second sample of 24 patients with HF using validation quantitative polymerase chain reaction. Results: A total of 334 genes (279 upregulated, 55 downregulated) were differentially expressed between patients with and without pain in the primary sample of 40. These genes were largely aligned with neutrophil degranulation pathways. Seven genes of interest were identified from a core network of 15 co-expressed genes in the PPI network and existing literature. Three of these seven genes: matrix metallopeptidase 8 (MMP8), proprotein convertase subtilisin/kexin type 9 (PCSK9), and neutrophil defensin 3 (DEFA3) were upregulated in patients with pain versus without pain in both the primary and validation samples. All seven genes of interest are involved in immune, inflammatory, and atherosclerotic processes. Discussion: These results identify potential genes that may play a mechanistic role in chronic pain in HF. Further research is needed to evaluate these potential genes among clearly delineated pain phenotypes.
Does pain at hospital discharge predict transition from hospital to home and 12-month mortality among patients with heart failure?
(N/A, 2022-11) Smith, Asa; Jung, Miyeon; Pressler, Susan
Introduction: Pain is present in 37%-68.9% of hospitalized patients with heart failure (HF), but little is known about how pain at discharge influences transition from hospital to home or 12-month mortality. The aims were to examine if pain at discharge predicts 1) return to home status and 2) 12-monthmortality among hospitalized patients with HF. Methods: In this prospective study, data were obtained from a dataset of 1,475 patients with HF hospitalized at 3 tertiary-care hospitals from 2009-2017. Pain at discharge (yes/no) was obtained from medical records using ICD-9 or ICD-10 codes. Return to home status (yes/no) and all-cause 12-month mortality were obtained from medical records. Descriptive statistics, independent samples t-tests, and χ2 were used to describe the sample. Logistic regression was computed to address the aims. Results: The sample was 59.5% women and 40.5% men. The mean age was 68.6 (SD 13.6) years. Race was 53.6% Black and 46.4% White. Of 1,475 patients, 239 (16.2%) had pain documented at discharge. Patients with pain documented at discharge were younger compared to patients without pain (p<.001). One hundred sixty-five of 239 patients (69.0%) with pain and 831 of1,236 patients (67.2%) without pain returned to home (χ2=0.297, p=.585). At 12 months after discharge, 20 of 239 patients (8.4%) with pain had died compared to 134 of 1,236 patients (10.8%) without pain (χ2=1.31, p=.252). In logistic regressions, pain at hospital discharge was not a statistically significant predictor of return to home status or 12-month mortality (Table 1). Conclusions: Over 30% of patients with HF did not return to home after hospitalization. Patients with HF have significant transitional care needs, including pain management. Future studies are needed to determine the phenotypes of pain among patients with HF, evaluate associations between pain at discharge and transitional care needs, and design innovative strategies to ameliorate pain.
