Associations between emergency department crowding and perceptions of interpersonal care in patients presenting with suspected acute coronary syndrome.

BACKGROUND: Emergency department (ED) crowding is associated with numerous healthcare issues, but little is known about its effect on psychosocial aspects of patient-provider interactions or interpersonal care. We examined whether ED crowding was associated with perceptions of interpersonal care in patients evaluated for acute coronary syndrome (ACS). METHODS: Patients presenting to a quaternary academic medical centre ED in New York City for evaluation of suspected ACS were enrolled between November 2013 and December 2016. ED crowding was measured using the ED Work Index (EDWIN), which incorporates patient volume, triage category, physician staffing and bed availability. Patients completed the 18-item Interpersonal Processes of Care (IPC) survey, which assesses communication, patient-centred decision-making and interpersonal style. Regression analyses examined associations between EDWIN and IPC scores, adjusting for demographics, comorbidities and depression. RESULTS: Among 933 included patients, 11% experienced ED overcrowding (EDWIN score >2) at admission, 11% experienced ED overcrowding throughout the ED stay and 30% reported suboptimal interpersonal care (defined as per-item IPC score <5). Higher admission EDWIN score was associated with modestly lower IPC score in both unadjusted (ß=-1.70, 95% CI -3.15 to -0.24, p=0.02) and adjusted models (ß = -1.77, 95% CI -3.31 to -0.24, p=0.02). EDWIN score averaged over the entire ED stay was not significantly associated with IPC score (unadjusted ß=-1.30, 95% CI -3.19 to 0.59, p=0.18; adjusted ß=-1.24, 95% CI -3.21 to 0.74, p=0.22). CONCLUSION: Increased crowding at the time of ED admission was associated with poorer perceptions of interpersonal care among patients with suspected ACS.

Long-term cardiac outcomes of depression screening, diagnosis and treatment in patients with acute coronary syndrome: the DEPACS study.

BACKGROUND: To investigate the impacts of depression screening, diagnosis and treatment on major adverse cardiac events (MACEs) in acute coronary syndrome (ACS). METHODS: Prospective cohort study including a nested 24-week randomised clinical trial for treating depression was performed with 5-12 years after the index ACS. A total of 1152 patients recently hospitalised with ACS were recruited from 2006 to 2012, and were divided by depression screening and diagnosis at baseline and 24-week treatment allocation into five groups: 651 screening negative (N), 55 screening positive but no depressive disorder (S), 149 depressive disorder randomised to escitalopram (E), 151 depressive disorder randomised to placebo (P) and 146 depressive disorder receiving medical treatment only (M). RESULTS: Cumulative MACE incidences over a median 8.4-year follow-up period were 29.6% in N, 43.6% in S, 40.9% in E, 53.6% in P and 59.6% in M. Compared to N, screening positive was associated with higher incidence of MACE [adjusted hazards ratio 2.15 (95% confidence interval 1.63-2.83)]. No differences were found between screening positive with and without a formal depressive disorder diagnosis. Of those screening positive, E was associated with a lower incidence of MACE than P and M. M had the worst outcomes even compared to P, despite significantly milder depressive symptoms at baseline. CONCLUSIONS: Routine depression screening in patients with recent ACS and subsequent appropriate treatment of depression could improve long-term cardiac outcomes.

The effect of patient education based on health belief model on hospital readmission preventive behaviors and readmission rate in patients with a primary diagnosis of acute coronary syndrome: a quasi-experimental study.

BACKGROUND: The health belief model is one of the applicable methods of training health preventive behaviors, especially in patients with cardiovascular diseases. Therefore, this study aimed to determine the effect of patient education based on the health belief model on readmission preventive behaviors and readmission rate in patients with a primary diagnosis of acute coronary syndrome. METHODS: The present quasi-experimental study was conducted in 2020 on patients with a primary diagnosis of acute coronary syndrome who were discharging from Seyed Al-Shohada Hospital, Urmia, Iran. In this study, a total of 70 samples were recruited using convenience sampling and then randomly assigned to two groups of intervention and control (n = 35 in each group). A total of 7 face-to-face group training sessions were held with the participation of the patients and one of their family members during 14 days after hospital discharge. These sessions were conducted along with concentration on the structures of the health belief model. Data were collected at three time points of immediately before, one month, and three months after the intervention using a demographic questionnaire, a researcher-made questionnaire of readmission preventive behaviors in cardiovascular diseases, and a checklist of hospital readmission. Data were analyzed using SPSS Statistics for Windows, version 17.0 (SPSS Inc., Chicago, Ill., USA). RESULTS: The results showed that there was a statistically significant difference in the mean score of preventive behaviors between the two groups at time points of one month and three months after the intervention (p < .05). However, there was no statistically significant difference in the readmission rate between the two groups after the intervention (p > .05). CONCLUSION: Health belief model-based education was shown to be effective on readmission preventive behaviors in patients with acute coronary syndrome, although this model had no effect on the readmission rate in these patients. Other factors affecting the readmission rate are recommended to be investigated.

Chinese patients' clinical and psychosocial outcomes in the 6 months following percutaneous coronary intervention.

BACKGROUND: In China, there has been a precipitous increase in the number of percutaneous coronary interventions (PCI) conducted. We sought to characterize the clinical and psychosocial trajectory of PCI patients from the time of procedure through 6 months post, and correlates of adverse cardiovascular events (ACEs). METHODS: In this prospective, observational study, patients from 2 hospitals in Shanghai, China were assessed. At follow-up visits at 1, 3 and 6 months post-PCI, clinical indicators were again extracted from patients' clinical records, including ACEs, and they completed validated surveys assessing self-management, as well as psychosocial indicators (Hospital Anxiety and Depression Scale; Pittsburgh Sleep Quality Index; quality of life [QoL]: SF-12, Seattle Angina Questionnaire [SAQ]). Repeated measures analysis of variance, adjusted for Barthel index and PCI indication, was used to assess change over time in risk factors and psychosocial indicators. Logistic regression was used to explore correlates of ACEs. RESULTS: 610 participants (mean age = 63.3; n = 150, 18.2% female) were recruited, of which 491 (80.5%) were retained at 6 months. 82 (16.7%) had an ACE at any time point, including most commonly angina and stroke (only 1 death). Clinical indicators such as blood pressure (p < 0.031 for both), symptom burden (p < .01 on all subscales) and QoL (p < 0.001 for both, but started quite low) improved over 6 months. Anxiety and depressive symptoms were above threshold, and the latter worsened over time (p < 0.001). With adjustment for age and indication, patients with any ACEs had higher sleep latency (odds ratio [OR] = 1.48; 95% confidence interval [CI] = 1.03-2.10]), and depressive symptoms (OR = 1.20; 95% CI = 1.02-1.41), but lower anxiety (OR = 0.79; 95% CI = 0.67-0.93) compared to those without. CONCLUSION: Centers may wish to re-visit patient selection criteria and processes for PCI, as well as implement mental health screening and treatment protocols, as can be achieved through cardiac rehabilitation, given how hazardous psychosocial distress is in this population.

Effects of clinical depression on left ventricular dysfunction in patients with acute coronary syndrome.

Depression is associated with heart failure independent of traditional cardiovascular disease risk factors. Enhanced platelet activation has been suggested as a potential mechanism and has been associated with negative inotropic effects that can affect left ventricular ejection fraction (LVEF). We examined 131 consecutive acute coronary syndrome (ACS) patients to assess whether depression increased the risk for developing LV dysfunction, and to determine the effects of platelet serotonin signaling in this relationship. Major depression was assessed using the Structured Clinical Interview and depressive symptoms were measured using the Beck Depression Inventory (BDI), with BDI ≥ 10 defined as abnormal. LV dysfunction was defined as LVEF ≤ 45%. Platelet serotonin response was measured by serotonin augmented platelet aggregation and platelet serotonin receptor density. Mean age of ACS participants was 59 years, 78.6% male and 74.0% Caucasian. 34.4% of patients had a reduced LVEF ≤ 45% on presentation. Almost half (47.0%) of patients had BDI ≥ 10 and 18.0% had major depressive disorder. Platelet serotonin response was found to be augmented in depressed patients with low LVEF compared to depressed patients with normal LVEF (p < 0.020). However, the presence of LV dysfunction was found to be similar in both depressed (32.3%) and non-depressed (36.2%) patients (p = 0.714). This suggests alternative factors contribute to poor cardiovascular outcomes in depressed patients that are independent of LV function in post ACS patients.

Prevention of depression in adults with long-term physical conditions.

BACKGROUND: Major depression is one of the world's leading causes of disability in adults with long-term physical conditions compared to those without physical illness. This co-morbidity is associated with a negative prognosis in terms of increased morbidity and mortality rates, increased healthcare costs, decreased adherence to treatment regimens, and a substantial decline in quality of life. Therefore, preventing the onset of depressive episodes in adults with long-term physical conditions should be a global healthcare aim. In this review, primary or tertiary (in cases of preventing recurrences in those with a history of depression) prevention are the focus. While primary prevention aims at preventing the onset of depression, tertiary prevention comprises both preventing recurrences and prohibiting relapses. Tertiary prevention aims to address a depressive episode that might still be present, is about to subside, or has recently resolved. We included tertiary prevention in the case where the focus was preventing the onset of depression in those with a history of depression (preventing recurrences) but excluded it if it specifically focused on maintaining an condition or implementing rehabilitation services (relapse prevention). Secondary prevention of depression seeks to prevent the progression of depressive symptoms by early detection and treatment and may therefore be considered a 'treatment,' rather than prevention. We therefore exclude the whole spectrum of secondary prevention. OBJECTIVES: To assess the effectiveness, acceptability and tolerability of psychological or pharmacological interventions, in comparison to control conditions, in preventing depression in adults with long-term physical conditions; either before first ever onset of depressive symptoms (i.e. primary prevention) or before first onset of depressive symptoms in patients with a history of depression (i.e. tertiary prevention). SEARCH METHODS: We searched the Cochrane Common Mental Disorders Controlled Trials Register, CENTRAL, MEDLINE, Embase, PsycINFO and two trials registries, up to 6 February 2020. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of preventive psychological or pharmacological interventions, specifically targeting incidence of depression in comparison to treatment as usual (TAU), waiting list, attention/psychological placebo, or placebo. Participants had to be age 18 years or older, with at least one long-term physical condition, and no diagnosis of major depression at baseline (primary prevention). In addition, we included studies comprising mixed samples of patients with and without a history of depression, which explored tertiary prevention of recurrent depression. We excluded other tertiary prevention studies. We also excluded secondary preventive interventions. Primary outcomes included incidence of depression, tolerability, and acceptability. Secondary outcomes included severity of depression, cost-effectiveness and cost-utility. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included 11 RCTs, with one trial on psychological interventions, and 10 trials on pharmacological interventions. Data analyses on the psychological intervention (problem-solving therapy compared to TAU) included 194 participants with age-related macular degeneration. Data analyses on pharmacological interventions included 837 participants comparing citalopram (one trial), escitalopram (three trials), a mixed sample of fluoxetine/nortriptyline (one trial), melatonin (one trial), milnacipran (one trial), and sertraline (three trials), each to placebo. Included types of long-term physical conditions were acute coronary syndrome (one trial), breast cancer (one trial), head and neck cancer (two trials), stroke (five trials), and traumatic brain injury (one trial). Psychological interventions Very low-certainty evidence of one study suggests that problem solving therapy may be slightly more effective than TAU in preventing the incidence of depression, immediately post-intervention (odds ratio (OR) 0.43, 95% confidence interval (CI) 0.20 to 0.95; 194 participants). However, there may be little to no difference between groups at six months follow-up (OR 0.71, 95% CI 0.36 to 1.38; 190 participants; one study; very low-certainty evidence). No data were available regarding incidence of depression after six months. Regarding acceptability (drop-outs due to any cause), slightly fewer drop-outs occurred in the TAU group immediately post-intervention (OR 5.21, 95% CI 1.11 to 24.40; 206 participants; low-certainty evidence). After six months, however, the groups did not differ (OR 1.67, 95% CI 0.58 to 4.77; 206 participants; low-certainty evidence). This study did not measure tolerability. Pharmacological interventions Post-intervention, compared to placebo, antidepressants may be beneficial in preventing depression in adults with different types of long-term physical conditions, but the evidence is very uncertain (OR 0.31, 95% CI 0.20 to 0.49; 814 participants; nine studies; I2 =0%; very low-certainty evidence). There may be little to no difference between groups both immediately and at six months follow-up (OR 0.44, 95% CI 0.08 to 2.46; 23 participants; one study; very low-certainty evidence) as well as at six to 12 months follow-up (OR 0.81, 95% CI 0.23 to 2.82; 233 participants; three studies; I2 = 49%; very low-certainty evidence). There was very low-certainty evidence from five studies regarding the tolerability of the pharmacological intervention. A total of 669 adverse events were observed in 316 participants from the pharmacological intervention group, and 610 adverse events from 311 participants in the placebo group. There was very low-certainty evidence that drop-outs due to adverse events may be less frequent in the placebo group (OR 2.05, 95% CI 1.07 to 3.89; 561 participants; five studies; I2 = 0%). There was also very low-certainty evidence that drop-outs due to any cause may not differ between groups either post-intervention (OR 1.13, 95% CI 0.73 to 1.73; 962 participants; nine studies; I2 = 28%), or at six to 12 months (OR 1.13, 95% CI 0.69 to 1.86; 327 participants; three studies; I2 = 0%). AUTHORS' CONCLUSIONS: Based on evidence of very low certainty, our results may indicate the benefit of pharmacological interventions, during or directly after preventive treatment. Few trials examined short-term outcomes up to six months, nor the follow-up effects at six to 12 months, with studies suffering from great numbers of drop-outs and inconclusive results. Generalisation of results is limited as study populations and treatment regimes were very heterogeneous. Based on the results of this review, we conclude that for adults with long-term physical conditions, there is only very uncertain evidence regarding the implementation of any primary preventive interventions (psychological/pharmacological) for depression.

Age, knowledge, preferences, and risk tolerance for invasive cardiac care.

BACKGROUND/OBJECTIVES: The extent to which individual knowledge, preferences, and priorities explain lower use of invasive cardiac care among older vs. younger adults presenting with acute coronary syndrome (ACS) is unknown. We directly surveyed a group of patients to ascertain their preferences and priorities for invasive cardiovascular care. DESIGN: We performed a prospective cohort study of adults hospitalized with ACS. We surveyed participants regarding their knowledge, preferences, goals, and concerns for cardiac care, as well as their risk tolerance for coronary artery bypass grafting (CABG). SETTING: Single academic medical center. PARTICIPANTS: Six hundred twenty-eight participants (373 <75 years old; 255 ≥75 years old). MEASUREMENTS: We compared baseline characteristics, knowledge, priorities, and risk tolerance for care across age strata. We also assessed pairwise differences with 95% confidence intervals (CI) between age groups for key variables of interest. RESULTS: Compared with younger patients, older participants had less knowledge of invasive care; were less willing to consider cardiac catheterization (difference between 75-84 and< 65 years old: -7.8%, 95% CI: -14.4%,-1.3%; for ≥85 vs. <65: -15.7%, 95% CI: -29.8%,-1.6%), percutaneous coronary intervention (difference between 75-84 and< 65 years old: -12.8%, 95% CI: -20.8%,-4.8%; for ≥85 vs. <65: -24.8%, 95% CI: -41.2%,-8.5%), and CABG (difference between 75-84 and< 65 years old: -19.0%, 95% CI: -28.2%,-9.9%; for ≥85 vs. <65: -39.1%, 95% CI: -56.0%,-22.2%); and were more risk averse for CABG surgery (p < .001), albeit with substantial inter-individual variability and individual outliers. Many patients who stated they were not initially willing to undergo an invasive cardiovascular procedure actually ended up undergoing the procedure (49% for cardiac catheterization and 22% for PCI or CABG). CONCLUSION: Age influences treatment goals and willingness to consider invasive cardiac care, as well as risk tolerance for CABG. Individuals' willingness to undergo invasive cardiovascular procedures loosely corresponds with whether that procedure is performed after discussion with the care team.

Sequential Combination of Cognitive-Behavioral Treatment and Well-Being Therapy in Depressed Patients with Acute Coronary Syndromes: A Randomized Controlled Trial (TREATED-ACS Study).

INTRODUCTION: Randomized controlled trials (RCT) of psychotherapeutic interventions have addressed depression and demoralization associated with acute coronary syndromes (ACS). The present trial introduces psychological well-being, an increasingly recognized factor in cardiovascular health, as a therapeutic target. OBJECTIVE: This study was designed to determine whether the sequential combination of cognitive-behavioral therapy (CBT) and well-being therapy (WBT) may yield more favorable outcomes than an active control group (clinical management; CM) and to identify subgroups of patients at greater risk for cardiac negative outcomes. METHODS: This multicenter RCT comparedCBT/WBT sequential combination versus CM, with up to 30 months of follow-up. One hundred consecutive depressed and/or demoralized patients (out of 740 initially screened by cardiologists after a first episode of ACS) were randomized to CBT/WBT associated with lifestyle suggestions (n = 50) and CM (n = 50). The main outcome measures included: severity of depressive symptoms according to the Clinical Interview for Depression, changes in subclinical psychological distress, well-being, and biomarkers, and medical complications and events. RESULTS: CBT/WBT sequential combination was associated with a significant improvement in depressive symptoms compared to CM. In both groups, the benefits persisted at follow-up, even though the differences faded. Treatment was also related to a significant amelioration of biomarkers (platelet count, HDL, and D-dimer), whereas the 2 groups showed similar frequencies of adverse cardiac events. CONCLUSIONS: Addressing psychological well-being in the psychotherapeutic approach to ACS patients with depressive symptoms was found to entail important clinical benefits. It is argued that lifestyle changes geared toward cardiovascular health may be facilitated by a personalized approach that targets well-being.

Feasibility and validity of Ecological Momentary Assessment in patients with acute coronary syndrome.

BACKGROUND: In recent years, Ecological Momentary Assessment (EMA) has expanded rapidly in healthcare research but its application specifically to the field of cardiology has been limited. This study presents essential information concerning the feasibility and validity of EMA in patients with acute coronary syndrome. METHODS: Four months after a first-ever acute coronary syndrome, 47 patients completed EMA five times a day for seven consecutive days concerning their current activities, mood and perceived negativity or positivity of daily events. RESULTS: Compliance with the repeated electronic assessments was high, and no evidence was found for time-dependent biases such as fatigue or practice effects. The resulting EMA data were found to have high internal validity, high reliability when considering average scores, and low reliability when considering within-person variance. CONCLUSIONS: We found evidence for the feasibility and intrinsic validity of EMA in patients with acute coronary syndrome. Research examining daily life experiences, symptoms and therapeutic adherence in this population can be reinforced through the use of mobile technologies.

Partner presence in the emergency department and adherence to daily cardiovascular medications in patients evaluated for acute coronary syndrome.

Stressful health situations may compromise spouses'/partners' ability to provide patients with support. We tested whether partner status/partner presence in the emergency department (ED) were associated with patients' adherence to daily cardiovascular medications and whether effects differed by age/gender. Participants were 189 patients evaluated for acute coronary syndrome at an urban academic ED (MAge = 62.18; 57.1% male; 58.7% Hispanic). Participants self-reported partner status/partner presence. Medication adherence was measured using an electronic pillcap. For male patients, having a partner was associated with increased adherence in the first month post-discharge, OR 1.94, p < .001, but having a partner present in the ED was associated with lower adherence, OR 0.33, p < .001. The opposite effect was evident for female patients. Partner status/partner presence in the ED are associated with medication adherence during the first month post discharge, with opposing effects for male and female patients.

Vietnamese version of the coronary artery disease education questionnaire-Short version: Translation, adaptation and validation.

WHAT IS KNOWN AND OBJECTIVE: Coronary artery disease (CAD) is the leading cause of mortality worldwide. Patient education is an essential part of cardiac patients' care targeting self-management behaviour to reduce risk factors and subsequent events. There has been no Vietnamese questionnaire to assess patient's knowledge about CAD; therefore, the purpose of this study was to translate, cross-culturally adapt and validate the Coronary Artery Disease Education Questionnaire-Short Version (CADE-Q SV) for use in Vietnam. METHODS: Translation and cross-cultural adaption of the tool were carried out in five stages: (a) two independent translations from English into Vietnamese were produced; (b) these two translations were then synthesized; (c) two translators blinded to the outcome measurements independently created separate back translations into English; (d) nine experts reached consensus on all items of the Vietnamese version of the CADE-Q SV; and (e) a pilot study was conducted on 35 patients with acute coronary syndrome (ACS). The validity and reliability of the questionnaires were then evaluated in 117 Vietnamese patients with ACS. The internal consistency and test-retest reliability were assessed by Cronbach's alpha and Cohen's kappa coefficient, respectively. Construct validity was determined by examining the relationship between knowledge scores and patient characteristics. RESULTS: The Vietnamese version of CADE-Q SV was created, including 20 items divided into two domains: medical and psychological condition, and nutrition and exercise. There was good equivalence between the original and the Vietnamese versions in all four areas: semantic, idiomatic, experiential and conceptual equivalence. Cronbach's alpha coefficients were acceptable for the questionnaire as a whole (0.78) and for the two domains: medical and psychological condition (0.71) and nutrition and exercise (0.52). All Cohen's kappa coefficients confirmed test-retest reliability (Kappa > 0.600; P < .001). Construct validity was confirmed by a significant correlation of knowledge scores with education level (P = .004). WHAT IS NEW AND CONCLUSION: The Vietnamese version of CADE-Q SV can be considered a valid and reliable questionnaire to evaluate patient's knowledge of CAD. Further studies could investigate the influence of knowledge scores on adherence to medications and clinical outcomes of patients with CAD.

Compliance of Patients with Acute Coronary Syndrome with Treatment Following Their Hospitalization from the Cardiac Coronary Unit.

BACKGROUND: Low compliance rates with medication after an acute coronary syndrome (ACS) is a serious public health problem with adverse socioeconomic implications for both patients and their families as well as for health systems in general. The aims of the study are to measure the levels of compliance with medication in the treatment of patients who suffered from ACS and to investigate the factors contributing to the noncompliance. METHODS: The sample consisted of 100 patients hospitalized in the coronary care unit (CCU) of a general hospital. The compliance of patients with treatment, which was measured with the GR-SMAQ and ARMS scales, was measured at 3, 6, and 12 months after their hospitalization. The t-test and control X2 were used, and the value of statistical significance was set to 0.05. RESULTS: According to the GR-SMAQ and ARMS scales, compliance of patients at 3, 6, and 12 months after hospitalization is low (58%, 70%, 32% with ARMS scale and 54%, 58%, 38% with GR-SMAQ scale, respectively). Patients who were readmitted to CCU had 68.9% less chances of showing compliance, and patients who had normal levels of systolic blood pressure were 3.5 times more likely to adhere to their treatment. No correlation between compliance and social demographic data, such as gender, age, level of study, and family and occupational status, was found (p > 0.05). CONCLUSION: Compliance of patients who suffered from ACS is at low level. There is a need for closed monitoring and use of wearable devices in order to improve the compliance rates.

Sex Differences in Prodromal Symptoms and Individual Responses to Acute Coronary Syndrome.

BACKGROUND: Although researchers have shown that prodromal symptoms can predict acute coronary events, the ability of patients with acute coronary syndrome (ACS) to identify these symptoms in a timely manner is limited. OBJECTIVES: We aimed to assess prodromal symptoms in Chinese patients with ACS and their responses to symptoms by sex. DESIGN: This cross-sectional, multicenter study involved 5 teaching hospitals in China and included 806 patients admitted for ACS between June 2013 and February 2014. The McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey (Chinese version) was used to gather data. RESULTS: Among 806 patients (including 483 women), 688 (85.4%) experienced at least 1 prodromal symptom before ACS onset. Using adjusted logistic regression models, we determined that women were significantly more likely than men to report back pain, between- or under-shoulder blade pain/discomfort, sleep disturbances, anxiousness, or heart racing. The prevalence of generalized chest pain and loss of appetite was higher among men than women. Only 41% of patients attributed their prodromal symptoms to the heart, and women were more likely than men to attribute prodromal symptoms to a heart attack. CONCLUSIONS: More than two-thirds of patients with ACS reported at least 1 prodromal symptom, with some significant sex differences. Most patients do not attribute their symptoms to an impending ACS event.

Warfarin control in Hong Kong clinical practice: a single-centre observational study.

INTRODUCTION: Time in therapeutic range (TTR) assesses the safety and effectiveness of warfarin therapy using the international normalised ratio. This study investigated the TTR in Hong Kong patients using both European and Japanese therapeutic ranges and patients' economic and clinical outcomes. Predictors of poor warfarin control and patient knowledge concerning warfarin therapy were assessed. METHODS: A 5-month observational study with retrospective and prospective components was conducted in the Prince of Wales Hospital. The study examined electronic patient records of patients who received warfarin for at least 1 year during the period from January 2010 to August 2015. Patient knowledge was assessed via phone interview using the Oral Anticoagulation Knowledge (OAK) test. RESULTS: In total, 259 patients were included; 174 completed the OAK test. The calculated mean TTR was 40.2±17.1% (European therapeutic range), compared with 49.1±16.1% (Japanese therapeutic range) [P<0.001]. Mean TTR was higher in patients with atrial fibrillation than in patients with prosthetic heart valve (P<0.001). The abilities of TTR to predict clinical and economic outcomes were comparable between European and Japanese therapeutic ranges. Patients with ideal TTR had fewer clinical complications and lower healthcare costs. Patients with younger age exhibited worse TTR, as did those with concurrent use of furosemide, famotidine, or simvastatin. Mean OAK test score was 54.1%. Only 24 (13.8%) patients achieved a satisfactory overall score of ≥75% in the test. CONCLUSION: Warfarin use in Hong Kong patients was poorly controlled, regardless of indication. Patient knowledge concerning warfarin use was suboptimal; thus, additional patient education is warranted regarding warfarin.

Thirty-day readmission, length of stay and self-management behaviour among patients with acute coronary syndrome and type 2 diabetes mellitus: A scoping review.

AIMS AND OBJECTIVES: To summarise the current evidence on comorbid type 2 diabetes mellitus (T2DM) related to 30-day readmission and hospital length of stay (LOS) among patients with acute coronary syndrome (ACS) and evidence on the effectiveness of self-management programmes for patients with both conditions. BACKGROUND: Acute coronary syndrome and T2DM remain two major diseases leading to serious consequences. Thirty-day readmission and LOS were considered indicators of the quality of care, with the understanding that the potential significant effects of these outcomes could be varied. DESIGN: This scoping review followed the methodology described by Arksey and O'Malley. METHODS: Five databases including PubMed, Embase, Cochrane Library, Web of Science and CINAHL were searched, and a total of 20 articles involving 913,807 patients were included. Results were reported in accordance with PRISMA-ScR guidelines. RESULTS: The results indicated that patients with both ACS and T2DM have prolonged LOS and increased 30-day readmission rates. The findings supported that improvements in patient self-management behaviour for optimal health outcomes were partially successful by effective self-management programmes; however, few articles on intervention programmes specifically designed for patients with two conditions were found. CONCLUSION: Prolonged LOS and increased 30-day readmission rates are found among patients with ACS and T2DM. Based on few pilot studies building on each other, the effectiveness of self-management programmes in promoting self-care behaviour, self-efficacy and knowledge for patients with ACS and T2DM cannot be concluded. RELEVANCE TO CLINICAL PRACTICE: Findings from this review provide valuable information on and a better understanding of readmissions and LOS among patients with ACS and T2DM for healthcare providers. Future developments and implementations of effective self-management programmes should target patients with dual diagnoses to improve health behaviour and reduce readmission and LOS.

Modifying effects of depression on the association between BDNF methylation and prognosis of acute coronary syndrome.

AIMS: Brain-derived neurotrophic factor (BDNF) plays important roles in angiogenesis, inflammation, and neuronal plasticity. BDNF methylation has been extensively investigated in depression, but not in cardiac diseases. We asked whether BDNF methylation status is associated with a major adverse cardiac event (MACE), inflammation, and the association with depression comorbidity and its treatment in patients with acute coronary syndrome (ACS). METHODS AND RESULTS: A cross-sectional baseline study and nested 24 week double-blind escitalopram placebo-controlled trial (ClinicalTrial.gov identifier NCT00419471) were performed from 2006 to 2012, with 5-12 year follow-up for MACE. Patients with recent ACS (969 total) were divided into four groups according to depression comorbidity at baseline and treatment allocation: 591, absent depression; 127, depression on escitalopram; 128, depression on placebo; 123, depression on care as usual (CAU). BDNF methylation was measured in leucocyte DNA, and multiple demographic and clinical characteristics including interleukin 6 were evaluated as covariates at baseline. The primary outcome, time to first MACE (a composite of all-cause mortality, myocardial infarction and percutaneous coronary intervention), was investigated using Cox regression models after adjustment for covariates. Interleukin 6 level was significantly higher in patients with higher BDNF methylation values. Higher BDNF methylation was associated with increased MACE independent of confounding factors [HR (95% CI) = 1.45 (1.17-1.78)]. This association was significant in patients without depression [HR (95% CI) = 1.39 (1.01-1.90)] and depressive patients on placebo [HR (95% CI) = 1.72 (1.02-3.02)] or CAU [HR (95% CI) = 1.53 (1.01-2.61)], but not in those treated with escitalopram [HR (95% CI) = 1.00 (0.51-1.95)]. CONCLUSION: BDNF methylation was significantly associated with prognosis of ACS. Escitalopram may mitigate the deleterious effect of higher BDNF methylation in depressive patients with ACS. Further research is needed to elucidate the mechanistics and to assess the generalisability of these findings.

Religious practices and changes in health-related quality of life after hospital discharge for an acute coronary syndrome.

BACKGROUND: Religious beliefs and practices influence coping mechanisms and quality of life in patients with various chronic illnesses. However, little is known about the influence of religious practices on changes in health-related quality of life (HRQOL) among hospital survivors of an acute coronary syndrome (ACS). The present study examined the association between several items assessing religiosity and clinically meaningful changes in HRQOL between 1 and 6 months after hospital discharge for an ACS. METHODS: We recruited patients hospitalized for an ACS at six medical centers in Central Massachusetts and Georgia (2011-2013). Participants reported making petition prayers for their health, awareness of intercessory prayers by others, and deriving strength/comfort from religion. Generic HRQOL was assessed with the SF-36®v2 physical and mental component summary scores. Disease-specific HRQOL was evaluated using the Seattle Angina Questionnaire Quality of Life subscale (SAQ-QOL). We separately examined the association between each measure of religiosity and the likelihood of experiencing clinically meaningful increase in disease-specific HRQOL (defined as increases by ≥10.0 points) and Generic HRQOL (defined as increases by ≥3.0 points) between 1- and 6-months post-hospital discharge. RESULTS: Participants (n = 1039) were, on average, 62 years old, 33% were women, and 86% were non-Hispanic White. Two-thirds reported praying for their health, 88% were aware of intercessions by others, and 85% derived strength/comfort from religion. Approximately 42, 40, and 26% of participants experienced clinically meaningful increases in their mental, physical, and disease-specific HRQOL respectively. After adjustment for sociodemographic, psychosocial, and clinical characteristics, petition (aOR:1.49; 95% CI: 1.09-2.04) and intercessory (aOR:1.72; 95% CI: 1.12-2.63) prayers for health were associated with clinically meaningful increases in disease-specific and physical HRQOL respectively. CONCLUSIONS: Most ACS survivors in a contemporary, multiracial cohort acknowledged praying for their health, were aware of intercessory prayers made for their health and derived strength and comfort from religion. Patients who prayed for their health and those aware of intercessions made for their health experienced improvement in their generic physical and disease-specific HRQOL over time. Healthcare providers should recognize that patients may use prayer as a coping strategy for improving their well-being and recovery after a life-threatening illness.

Trajectories of perceived social support in acute coronary syndrome.

PURPOSE: Perceived social support is known to be an important predictor of health outcomes in patients with acute coronary syndrome (ACS). This study investigates patterns of longitudinal trajectories of patient-reported perceived social support in individuals with ACS. METHODS: Data are from 3013 patients from the Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease registry who had their first cardiac catheterization between 2004 and 2011. Perceived social support was assessed using the 19-item Medical Outcomes Study Social Support Survey (MOS) 2 weeks, 1 year, and 3 years post catheterization. Group-based trajectory analysis based on longitudinal multiple imputation model was used to identify distinct subgroups of trajectories of perceived social support over a 3-year follow-up period. RESULTS: Three distinct social support trajectory subgroups were identified, namely: "High" social support group (60%), "Intermediate" social support group (30%), and "Low" social support subgroup (10%). Being female (OR = 1.67; 95% CI = [1.18-2.36]), depression (OR = 8.10; 95% CI = [4.27-15.36]) and smoking (OR = 1.70; 95% CI = [1.23-2.35]) were predictors of the differences among these trajectory subgroups. CONCLUSION: Although the majority of ACS patients showed increased or fairly stable trajectories of social support, about 10% of the cohort reported declining social support. These findings can inform targeted psycho-social interventions to improve their perceived social support and health outcomes.

Artificial FLOwering plants in Reducing Anxiety and depressive symptoms following Acute Coronary Syndromes (A-FLORA-ACS): a randomised controlled trial.

Patients often experience emotional distress after acute coronary syndrome (ACS). These may lead to symptoms of depression or anxiety and greater morbidity/mortality. We sought to determine whether flowering plants in the coronary care ward reduced depressive and anxiety symptoms in these patients. Patients with ACS were randomly allocated to flowering plants (intervention) or no plants (control) in their room during index hospitalisation. Baseline data were collected. The primary outcome was the Hospital Anxiety and Depression Scale (HADS) depressive and anxiety symptom scores at discharge. Secondary outcomes were HADS depression and anxiety scores at 3 months. Both modified intention-to-treat (mITT) and per-protocol (PP) analysis were performed. 122 patients were included in the analysis after case exclusion, with all completing the HADS questionnaire at discharge and 89/122 (73%) patients completing the 3-month post-discharge HADS. At discharge, mean depressive symptom scores were lower in the intervention group, but only significantly so in the PP analysis (mITT 3.6/21 vs 4.6/21, p = 0.11; PP 3.5/21 vs 4.9/21, p = 0.04). There were no significant changes in between-group anxiety symptom scores (mITT 6.4/21 vs 6.1/21, p = 0.51; PP 3.3/21 vs 3.6/21, p = 0.67). The mean increase in depressive symptom scores at 3 months was smaller in the intervention group in both analyses (mITT 0.6 ± 3.6 vs 2.2 ± 2.6, p = 0.02; PP 0.8 ± 3.6 vs 2.4 ± 2.7, p = 0.03). Mean increase in anxiety symptom scores was not significantly different between groups (mITT 2.8/21 vs 2.5/21, p = 0.86; PP 3.3/21 vs 3.6/21, p = 0.67). Flowering plants during index hospitalisation for ACS reduced depressive symptoms in a per-protocol analysis but did not have a significant impact on anxiety symptoms. Increases in depression symptom scores were significantly smaller at 3 months post exposure to flowers compared to anxiety symptom scores.

Determinants of Return to Work After Multicomponent Cardiac Rehabilitation.

OBJECTIVES: To explore predictors of return to work in patients after acute coronary syndrome and coronary artery bypass grafting, taking into account cognitive performance, depression, physical capacity, and self-assessment of the occupational prognosis. DESIGN: Observational, prospective, bicentric. SETTING: Postacute 3-week inpatient cardiac rehabilitation (CR). PARTICIPANTS: Patients (N=401) <65 years of age (mean 54.5±6.3y), 80% men. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Status of return to work (RTW) 6 months after discharge from CR. RESULTS: The regression model for RTW showed negative associations for depression (odds ratio 0.52 per SD, 95% confidence interval 0.36-0.76, P=.001), age (odds ratio 0.72, 95% confidence interval 0.52-1.00, P=.047), and in particular for a negative subjective occupational prognosis (expected incapacity for work odds ratio 0.19, 95% confidence interval 0.06-0.59, P=.004; unemployment odds ratio 0.08, 95% confidence interval 0.01-0.72, P=.024; retirement odds ratio 0.07, 95% confidence interval 0.01-0.067, P=.021). Positive predictors were employment before the cardiac event (odds ratio 9.66, 95% confidence interval 3.10-30.12, P<.001), capacity to work (fit vs unfit) at discharge from CR (odds ratio 3.15, 95% confidence interval 1.35-7.35, P=.008), and maximum exercise capacity (odds ratio 1.49, 95% confidence interval 1.06-2.11, P=.022). Cognitive performance had no effect. CONCLUSIONS: The patient's perception and expectation regarding the occupational prognosis play a crucial role in predicting return to work 6 months after an acute cardiac event and CR. These findings highlight the importance of the multimodal approach, in particular psychosocial components, of CR.
