RESUMO
BACKGROUND AND PURPOSE: Vascular access site (VAS) bruising is common following invasive cardiac procedures. The extent of VAS bruising is underreported because of the lack of reliable measurement methods. This study examined the reliability of linear measurement and planimetry to measure VAS bruise size. METHODS: There were 40 participants with VAS bruising after invasive cardiac procedures who completed VAS bruise measurement. Participants, a principal investigator, and a research assistant completed measurements independently. Inter-rater reliability was determined using intraclass correlation coefficient (ICC), 2-way random effects model. RESULTS: The ICC for linear measurement and planimetry was high (.929 and .914 respectively). Both methods were reliable measures of VAS bruise size. CONCLUSIONS: Linear measurement or planimetry can be used with confidence to measure VAS bruising in clinical and research contexts.

BACKGROUND: Chronic stable angina (CSA) has a major negative impact on health-related quality of life (HRQL) including poor general health status, psychological distress, and inability to self-manage. METHODS: We used meta-analysis to assess the effectiveness of self-management interventions for improving stable angina symptoms, HRQL and psychological well-being. Nine trials, involving 1,282 participants in total, were included. We used standard inverse-variance random-effects meta-analysis to combine the trials. Heterogeneity between trials was evaluated using chi-square tests for the tau-squared statistic and quantified using the I2 statistic. RESULTS: There was significant improvement in the frequency of angina symptoms (Seattle Angina Questionnaire [SAQ], symptom diary) across trials, standardized mean difference (SMD): 0.30 (95% Confidence interval [CI] 0.14, 0.47), as well as reduction in the use of sublingual (SL) nitrates, SMD: -0.49 (95% CI -0.77, -0.20). Significant improvements for physical limitation (SAQ), SMD: 0.38 (95% CI 0.20, 0.55) and depression scores (Hospital Anxiety and Depression Scale), SMD: -1.38 (95% CI -2.46, -0.30) were also found. The impact of SM on anxiety was uncertain due to statistical heterogeneity across trials for this outcome, I2 = 98%. SM did not improve other HRQL dimensions including angina stability, disease perception, and treatment satisfaction. CONCLUSIONS: SM interventions significantly improve angina frequency and physical limitation; they also decrease the use of SL nitrates and improve depression in some cases. Further work is needed to make definitive conclusions about the impact of SM on cardiac-specific anxiety.

AIM: To identify the prevalence and predictors of VAS bruising in the 5-7 days following cardiac catheterisation or percutaneous coronary intervention. BACKGROUND: Complication(s) of cardiac catheterisation and/or percutaneous coronary intervention (PCI) occur commonly at the vascular access site (VAS). While major complications, such as retroperitoneal bleeding, are evident before hospital discharge, the prevalence of VAS bruising in the early post-discharge period is undocumented. DESIGN: Prospective observational study. METHOD: Data were collected on 172 patients following cardiac catheterisation and/or PCI through (1) chart review, (2) pre-discharge assessment and (3) telephone follow up 5-7 days post-discharge. RESULTS: At the time of telephone follow up bruising was reported in 68.6% of all patients (n = 118), with 47% of those patients (n = 56) reporting bruises larger than 7.5 cm (3 inches). Incidence of bruising varied by access site; 73% of patients (n = 86) who had femoral access, 83% (n = 5) with femoral access plus closure device and 60% (n = 17) of patients with radial access reported bruising 5-7 days post-discharge. Bivariate analysis revealed a significant association between female sex and post discharge bruising (χ(2) 10.490, p = 0.001), with a likelihood ratio of 11.20. Abciximab use during the procedure was associated with post discharge bruising (Fisher's exact test, p = 0.045). Logistic regression analysis revealed female sex as a significant predictor of bruising after discharge (p = 0.001). CONCLUSION: This study suggests that the majority of patients will experience significant bruising at the VAS following discharge and that women may be more at risk. RELEVANCE TO CLINICAL PRACTICE: The high prevalence of post-discharge bruising after cardiac catheterisation and/or PCI has important implications for nursing education and preparation of patients prior to hospital discharge.

BACKGROUND: Human epidermal growth factor receptor 2 (HER2) overexpressing malignancies, including breast and gastro-esophageal, are associated with a poor prognosis. The cardiotoxicity of trastuzumab, a HER2-targeting monoclonal antibody, is well established. However, the cardiotoxic effect of pertuzumab, another HER2-directed therapy, is less well documented. The objective of this systematic review and meta-analysis was to determine the risk of cardiac events in patients with HER2-positive cancer who are receiving pertuzumab. METHODS: We performed a systematic review of phase 2 and 3 randomized controlled trials in which the addition of pertuzumab to other standard therapies in patients with stage I-IV HER2-positive cancer was evaluated, and cardiac adverse effects reported. We searched MEDLINE (1946-2020), Embase (1974-2020), and CENTRAL. Two independent reviewers assessed the risk of bias and extracted the data. Risk ratios (RRs) with 95% confidence intervals (CIs) were calculated from the pooled data using the inverse variance method and random-effects models. RESULTS: Eight randomized controlled trials (8420 patients) were included: 1 was gastro-esophageal; 7 were breast cancer trials. Participants' median age ranged from 49 to 61.5 years. All participants received trastuzumab and chemotherapy in addition to pertuzumab or placebo. Compared with placebo, pertuzumab increased the risk of clinical heart failure (HF; RR [95% CI]: 1.97 [1.05-3.70]; I2 = 0%). However, pertuzumab had no demonstrable effect on asymptomatic/minimally symptomatic left ventricular systolic dysfunction (RR [95% CI]: 1.19 [0.89-1.61]; I2 = 19%). CONCLUSIONS: Pertuzumab increases the risk of clinical HF, but not asymptomatic/minimally symptomatic left ventricular systolic dysfunction, in HER2-positive cancer patients. Further research into the mechanisms underlying pertuzumab-related HF is needed to understand its clinical spectrum of cardiotoxicity.
INTRODUCTION: Les tumeurs malignes qui surexpriment le récepteur 2 du facteur de croissance épidermique humain (HER2, de l'anglais Human epidermal growth factor receptor 2), notamment le cancer du sein et le cancer de la jonction gastro-Åsophagienne, sont associées à un mauvais pronostic. La cardiotoxicité du trastuzumab, un anticorps monoclonal qui vise le HER2, est bien établie. Toutefois, les effets cardiotoxiques du pertuzumab, un autre traitement qui vise le HER2, sont moins bien démontrés. L'objectif de cette revue systématique et de cette méta-analyse était de déterminer le risque d'événements cardiaques chez les patients atteints d'un cancer HER2 positif qui prennent du pertuzumab. MÉTHODES: Nous avons réalisé une revue systématique d'essais comparatifs à répartition aléatoire de phase 2 et de phase 3 lors desquels nous avons évalué l'ajout du pertuzumab à d'autres traitements standards chez les patients atteints d'un cancer HER2 positif de stades I-IV, et signalé les effets indésirables sur le cÅur. Nous avons fait des recherches dans MEDLINE (1946-2020), Embase (1974-2020) et CENTRAL. Deux examinateurs indépendants ont évalué le risque de biais et extrait les données. Les données groupées ont permis de calculer les intervalles de confiance (IC) à 95 % des risques relatifs (RR) au moyen de la méthode de la variance inverse et des modèles à effets aléatoires. RÉSULTATS: Nous avons inclus huit essais contrôlés randomisés (8420 patients), soit un qui portait sur le cancer de la jonction gastro-Åsophagienne, et sept sur le cancer du sein. L'âge médian des participants se situait entre 49 à 61,5 ans. Tous les participants ont pris le trastuzumab et ont suivi une chimiothérapie en plus de la prise du pertuzumab ou du placebo. Comparativement au placebo, le pertuzumab a fait augmenter le risque de manifestations cliniques de l'insuffisance cardiaque (IC) (RR [IC à 95 %] : 1,97 [1,05-3,70]; I2 = 0 %). Toutefois, le pertuzumab n'a démontré aucun effet sur la dysfonction systolique du ventricule gauche asymptomatique/minimalement symptomatique (RR [IC à 95 %] : 1,19 [0,89-1,61]; I2 = 19 %). CONCLUSIONS: Le pertuzumab fait augmenter le risque de manifestations cliniques de l'IC, mais pais la dysfonction systolique du ventricule gauche asymptomatique/minimalement symptomatique, chez les patients atteints d'un cancer HER2 positif. Des recherches plus approfondies sur les mécanismes sous-jacents à l'IC liée au pertuzumab sont nécessaires pour comprendre son spectre de manifestations cliniques de cardiotoxicité.
RESUMO
BACKGROUND: Patients with ST-segment elevation myocardial infarction (STEMI) have traditionally been hospitalized for 5 to 7 days to monitor for serious complications such as heart failure, arrhythmias, reinfarction, and death. The Zwolle Primary Percutaneous Coronary Intervention (PCI) Index is an externally validated risk score that has been used to identify low-risk STEMI patients who have undergone primary PCI and can safely be discharged from hospital within 72 hours. Previous studies have shown that many low-risk patients remain in hospital significantly longer. METHODS: We randomly assigned 54 low-risk STEMI patients treated with primary or rescue PCI to 1 of 2 groups. Patients in the intervention group (n = 27) were actively targeted for early hospital discharge (48-72 hours) and received outpatient follow-up with an advanced practice nurse (APN). In the control group (n = 27), discharge planning and follow-up were left to the treating physician, and there was no added nursing intervention. The 2 primary outcomes of this pilot study were to demonstrate feasibility and safety. Secondary outcomes included compliance with medications, smoking cessation, attendance at cardiac rehabilitation, and quality of life, measured in both groups at 6 weeks time. RESULTS: In the intervention group, 74% of patients were discharged within 72 hours, 100% had follow-up with the APN within 3 days (74% in person, 26% by phone), and 100% had >/= 3 APN follow-ups in total, meeting our prespecified criteria for feasibility. The median length of stay was 55 hours in both groups. There were no deaths in either group, and there was no difference in rehospitalization between patients in the intervention and control groups (8% vs 4%, P = .56). There was no difference in rates of medication compliance, smoking cessation, attendance at cardiac rehabilitation, or quality of life between the 2 groups, although our small pilot study was not powered to detect a difference in these outcomes. CONCLUSION: In low-risk STEMI patients treated with primary or rescue PCI, a strategy of early hospital discharge facilitated by close nursing follow-up is feasible. Although our study did not identify differences in compliance or quality of life between the 2 groups, it did provide a functional study design for a larger trial powered to detect these important clinical end points.

OBJECTIVES: This study sought to evaluate the safety of continuing trastuzumab in patients with human epidermal growth factor receptor-positive breast cancer who developed mild cardiotoxicity. BACKGROUND: Cardiotoxicity is the most common dose-limiting toxicity associated with trastuzumab. Current standard of care is discontinuation of trastuzumab, which can lead to worse cancer outcomes. It is unknown whether it is safe to continue trastuzumab despite mild cardiotoxicity. METHODS: Patients were eligible for this phase I, prospective, single-arm trial if left ventricular ejection fraction (LVEF) was between 40% and the lower limit of normal or if it fell ≥15% from baseline. Participants were treated with angiotensin-converting enzyme (ACE) inhibitors and/or beta-blockers in a cardio-oncology clinic and were followed clinically and with serial echocardiograms for 1 year. The primary outcome was cardiac dose-limiting toxicity, defined as cardiovascular death, LVEF <40% together with any heart failure symptoms, or LVEF <35%. RESULTS: All 20 participants received ACE inhibitors and/or beta-blockers. A total of 18 participants (90%) received all planned trastuzumab doses. Two (10%) participants developed cardiac dose-limiting toxicity (heart failure with LVEF <40%). Their LVEF and heart failure symptoms improved to nearly normal following permanent trastuzumab discontinuation. There were no deaths. LVEF rose progressively from a mean of 49% at enrollment to 55% at 12 months (p < 0.001). CONCLUSIONS: It may be feasible to continue trastuzumab despite mild cardiotoxicity in the setting of a cardio-oncology clinic, where ACE inhibitors and beta-blockers are administered. Approximately 10% of patients may develop moderate to severe heart failure using this approach.

RESUMO
AIM: While caregivers (CGs) make an important contribution to the self-care of heart failure (HF) patients, there are no reliable and valid tools for measuring such contributions. Current interventions that strive to optimize patient outcomes through self-care strategies neglect to account for CG contributions, a potential confounder on outcomes. The aim of the study was to develop an instrument that measures CG contributions to HF patients' self-care. DESIGN: The study design follows an established process for instrument development. METHODS: A systematic literature review and semi-structured interviews of CGs were conducted to identify measureable CG activities. Items were derived from thematic analysis of CG narratives. A content validity index was computed for each item (I-CVI). Items with an I-CVI of >0·70 were retained. Items with an I-CVI of 0·50-0·70 were revised for clarification and items with an I-CVI <0·5 were discarded, except in instances where fulsome theoretical or empirical evidence supported their retention. RESULTS: 14 CGs completed interviews and 10 CGs with 4 expert nurses completed I-CVI testing. Major interview themes included arranging appointments, medication adherence, monitoring, coordinating care, encouraging independence and taking action. A total of 36 items were constructed and underwent I-CVI testing. Following I-CVI testing, 27 items were retained, seven items were retained after revision based on CG feedback and two items were removed. This newly developed 34-item questionnaire represents current literature, CGs' experiences, excellent I-CVI scores and ready for further psychometric testing.
RESUMO
AIMS: The purpose of this study was to conduct a systematic review answering the following questions: (a) what specific activities do caregivers (CGs) contribute to patients' self-care in heart failure (HF)?; and (b) how mature (or developed) is the science of the CG contribution to self-care? METHODS: MEDLINE, EMBASE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), the Cochrane Library and ClinicalTrials.gov were searched using the terms heart failure and caregiv* as well as the keywords 'careers', 'family members' and 'lay persons' for studies published between 1948 and September 2012. Inclusion criteria for studies were: informal CGs of adult HF patients-either as dependent/independent variable in quantitative studies or participant in qualitative studies; English language. Exclusion criteria for studies were: formal CGs; pediatric, adult congenital, or devices or transplant CGs; mixed diagnosis; non-empiric reports or reports publishing duplicate results. Each study was abstracted and confirmed by two authors. After CG activities were identified and theoretically categorized, an analysis across studies was conducted. RESULTS: Forty papers were reviewed from a pool of 283 papers. CGs contribute substantively to HF patients' self-care characterized from concrete (weighing the patient) to interpersonal (providing understanding). Only two studies attempted to quantify the impact of CGs' activities on patients' self-care reporting a positive impact. Our analysis provides evidence for a rapidly developing science that is based largely on observational research. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: To our knowledge, this is the first systematic review to examine CGs' contributions in depth. Informal caregivers play a major role in HF self-care. Longitudinal research is needed to examine the impact of CGs' contributions on patient self-care outcomes.

BACKGROUND: The purpose of this study was to identify factors that predispose individuals to nonischemic chest pain following successful percutaneous coronary intervention (PCI). METHODS: We prospectively followed, for 6 months, a cohort of 110 patients who underwent PCI. We determined baseline factors associated with post PCI pain via nonlinear mixed model regression; a binomial distribution with logit link was used. RESULTS: The mean age of participants (n = 110) was 64 (SD ± 11.19), 69% were male. The majority had 1 coronary vessel dilated (88%) and a single stent placement (67%). During follow-up, chest pain was prevalent in 54% (95% confidence interval [CI], 44.8-63.7) and 45% (95% CI, 36.0-54.8) of patients, at 3 and 6 months respectively. Less than half of those with chest pain were evaluated for ischemia. Of those evaluated, tests were negative for the majority; 74% and 61% at 3 and 6 months respectively. Higher baseline depression (odds ratio 1.50; 95% CI, 1.13-1.99) scores (Hospital Anxiety Depression Scale) were significantly associated with nonischemic chest pain during follow-up. CONCLUSION: Higher baseline depression scores were found to be significant risk factors for chest pain of nonischemic origin following successful PCI. A larger study is needed to confirm the predictive value of this and other factors that may contribute to this elusive pain problem. Further research is also required to develop pain management strategies for patients whose chest pain persists in the absence of discernible ischemic causes.

Refractory angina (RFA) is a debilitating disease characterized by cardiac pain resistant to conventional treatments for coronary artery disease including nitrates, calcium-channel and ß-adrenoceptor blockade, vasculoprotective agents, percutaneous coronary interventions, and coronary artery bypass grafting. The mortality rate of patients living with RFA is not known but is thought to be in the range of approximately 3%. These individuals suffer severely impaired health-related quality of life with recurrent and sustained pain, poor general health status, psychological distress, impaired role functioning, and activity restriction. Effective care for RFA sufferers in Canada is critically underdeveloped. These guidelines are predicated upon a 2009 Canadian Cardiovascular Society (CCS) Position Statement which identified that underlying the problem of RFA management is the lack of a formalized, coordinated, interprofessional strategy between the cardiovascular and pain science/clinical communities. The guidelines are therefore a joint initiative of the CCS and the Canadian Pain Society (CPS) and make practice recommendations about treatment options for RFA that are based on the best available evidence. Concluding summary recommendations are also made, giving direction to future clinical practice and research on RFA management in Canada.
