Alternatives to Hospitalization: Adding the Patient Voice to Advanced Heart Failure Management.

Advanced heart failure (HF) is associated with the extensive use of acute care services, especially at the end of life, often in stark contrast to the wishes of most HF patients to remain at home for as long as possible. The current Canadian model of hospital-centric care is not only inconsistent with patient goals, but also unsustainable in the setting of the current hospital-bed availability crisis across the country. Given this context, we present a narrative to discuss factors necessary for the avoidance of hospitalization in advanced HF patients. First, patients eligible for alternatives to hospitalization should be identified through comprehensive, values-based, goals-of-care discussions, including involvement of both patients and caregivers, and assessment of caregiver burnout. Second, we present pharmaceutical interventions that have shown promise in reducing HF hospitalizations. Such interventions include strategies to combat diuretic resistance, as well as nondiuretic treatments of dyspnea, and the continuation of guideline-directed medical therapies. Finally, to successfully care for advanced HF patients at home, care models, such as transitional care, telehealth, collaborative home-based palliative care programs, and home hospitals, must be robust. Care must be individualized and coordinated through an integrated care model, such as the spoke-hub-and-node model. Although barriers exist to the implementation of these models and strategies, they should not prevent clinicians from striving to provide individualized person-centred care. Doing so will not only alleviate strain on the healthcare system, but also prioritize patient goals, which is of the utmost importance.

L'insuffisance cardiaque avancée est associée à une utilisation considérable des services de soins de courte durée, surtout en fin de vie et souvent en contradiction totale avec les désirs de la plupart des patients, qui sont de rester à la maison le plus longtemps possible. Le modèle canadien actuel, centré sur les soins hospitaliers, n'est pas seulement incompatible avec les objectifs des patients, mais il est n'est pas viable vu le manque criant de lits constaté dans des hôpitaux de partout au pays. En tenant compte de ce contexte, nous présentons une perspective permettant de discuter des facteurs nécessaires pour éviter l'hospitalisation des patients atteints d'insuffisance cardiaque avancée. Il faut d'abord identifier les patients admissibles à des soins non hospitaliers en menant des discussions exhaustives sur les objectifs de soins qui se fondent sur les valeurs et qui portent notamment sur la participation du patient et de ses aidants et sur l'évaluation de l'épuisement des aidants. Nous présentons ici les interventions pharmaceutiques qui se sont révélées prometteuses dans la réduction des hospitalisations pour cause d'insuffisance cardiaque. Il s'agit de stratégies visant à lutter contre la résistance aux diurétiques et de traitements non diurétiques de la dyspnée, ainsi que de la poursuite des traitements médicaux indiqués par les lignes directrices. Enfin, pour bien soigner les patients atteints d'insuffisance cardiaque avancée à domicile, les modèles de soins, comme les soins de transition, la télémédecine, les programmes collaboratifs de soins palliatifs à domicile et les programmes d'hospitalisation à domicile, doivent être robustes. Les soins doivent être personnalisés et coordonnés par un modèle de soins intégré, comme le modèle en étoile (spoke-hub-and-node). Bien qu'il existe des obstacles à l'instauration de ces modèles et stratégies, ceux-ci ne devraient pas empêcher les médecins de s'employer à offrir des soins adaptés axés sur la personne. Cette pratique libérera le système de santé d'un poids et permettra de mettre de l'avant les objectifs des patients, qui sont de la plus grande importance.

The Use of Intranasal Fentanyl for the Palliation of Incident Dyspnea in Advanced Congestive Heart Failure: A Pilot Study.

BACKGROUND:: Dyspnea is distressing in palliative patients with end-stage heart failure and many are hospitalized to optimize this symptom. We hoped to conduct a pilot study to determine whether the administration of intranasal fentanyl would decrease activity-induced dyspnea in this patient population. METHODS:: Patients performed two 6-minute walk tests with and without the administration of 50 µg of intranasal fentanyl. Vital signs were recorded before and after each walk, as were participant reported dyspnea and adverse events scores. RESULTS:: Twenty-four patients were screened, 13 were deemed eligible, and 6 completed the study. Dyspnea scores changed from a mean of 6.00 immediately after the walk without fentanyl to a mean of 3.83 after the walk with fentanyl ( P = .048). Mean respiratory rate decreased from 21.0 to 18.7 ( P = .034) breaths per minute and was considered a favorable outcome by the participants. Distance walked did not significantly increase with the fentanyl pretreatment (136.0-144.2 m; P = .283), although the participants reported feeling better while walking a similar distance. CONCLUSIONS:: In this pilot study, the preadministration of intranasal fentanyl prior to activity in palliative, end-stage hospitalized heart failure patients, safely reduced tachypnea, and the feeling of shortness of breath. This approach may help palliate advanced heart failure patients by alleviating symptoms brought on by exertional activities.

Peripartum Cardiomyopathy Characteristics and Outcomes in Canadian Aboriginal and Non-Aboriginal Women.

BACKGROUND: Peripartum cardiomyopathy (PPCM) is a heterogeneous condition characterized by heart failure and left ventricular dysfunction (left ventricular ejection fraction [LVEF] < 45%) in the absence of an alternative cause and a previous diagnosis of cardiomyopathy. The Aboriginal population (Inuit, First Nations, Metis) of Canada often has barriers to health care, which can lead to delays in diagnosis and treatment. Our objectives are to describe PPCM in a Canadian population, and to determine if Canadian Aboriginal women have worse clinical outcomes than non-Aboriginal women. METHODS: A retrospective study was performed at a single tertiary care centre, between 2008 and 2014. Demographic characteristics, symptoms at presentation, medical history, discharge medications, blood work, echocardiographic parameters, and follow-up information were collected. RESULTS: A total of 177 women were screened, and 23 were included in the study (52% were Aboriginal). Aboriginal women were found to have higher rates of gravidity and parity, and higher incidence of tobacco smoking than non-Aboriginal women, and were more likely to be discharged with diuretic medications. At diagnosis, Aboriginal women were more likely to have a lower LVEF (20% [interquartile range (IQR), 15%-23%] vs 40% [IQR, 30%-42%]; P = 0.02) and a more dilated left ventricle (left ventricular end-diastolic diameter, 64 mm [IQR, 57-74 mm] vs 54 mm [IQR, 50-57mm]; P < 0.01). Recovery rate, defined as LVEF > 50%, was similar (46% in Aboriginal patients and 60% in non-Aboriginal patients). CONCLUSIONS: Our findings support that Aboriginal women with PPCM are more likely to present with lower LVEF and a more dilated left ventricle, as well, require more symptomatic management. To our knowledge, this is the first description and contrast of PPCM between Aboriginal and non-Aboriginal Canadians.

End of life decisions in heart failure: to turn off the intracardiac device or not?

PURPOSE OF REVIEW: Heart failure is a significant public health concern around the world. Implantable cardioverter defibrillators with or without cardiac resynchronization therapy (CRT-D) have proven survival benefit. As patients progress to end-stage disease, management shifts to palliative care, and cardiologists are often confronted with how to best manage these devices. RECENT FINDINGS: Studies suggest that up to one-third of patients with an implantable cardioverter defibrillator receive painful shocks in the last 24 h of life. Disabling pacing or resynchronization devices may further weaken the heart function and expedite death, particularly if the patient has no underlying ventricular rhythm. Is it ethical or legal to discontinue functions of the implantable device? The discussion and the decision to be made are whether to continue both pacing and tachyarrhythmia therapies, disable tachyarrhythmia therapies while maintaining pacing, or discontinue both. SUMMARY: The decision to disable all or parts of the device function is ultimately up to the patient. To avoid painful shocks near the end of life, it is recommended that tachyarrhythmia therapies be turned off when the patient is being treated palliatively. After informed discussion, withdrawing the resynchronization or pacing device option is also acceptable if requested by the patient regardless of the potential outcomes.

The Urea-to-Creatinine Ratio Is Predictive of Worsening Kidney Function in Ambulatory Heart Failure Patients.

BACKGROUND: Changes in kidney function in heart failure patients convey important prognostic information. We investigated the association of the urea-to-creatinine (BUN/Cr) ratio, the fractional excretion of urea (FeUr), and the fractional excretion of sodium (FeNa) and subsequent declines in kidney function in ambulatory heart failure patients. METHODS AND RESULTS: We prospectively enrolled adult patients with ejection fraction <40% at a multidisciplinary heart failure clinic and measured serial measurements of laboratory values from September 2008 to July 2011. The study outcome was changes in the estimated glomerular filtration rate (eGFR). In 138 patients contributing 10,350 patient-hours of follow-up, we found that participants with a decline of >25% in eGFR had higher mean BUN/Cr ratio (0.110 ± 0.043 vs 0.086 ± 0.026; P = .02) and no difference in the FeNa (1.81 vs 1.43; P = .2) or FeUr (32.3 vs 37.2; P = .9) compared with those with no change. There was an association of BUN/Cr ratio with the rate of change of eGFR (coefficient -25.67, 95% confidence interval [CI] -10.99 to -40.35; P < .0001). The BUN/Cr ratio was an independent predictor of eGFR drop >25% (odds ratio 1.19, 95% CI 1.07-1.32) and improved model discrimination (c-statistic increased from 0.624 to 0.693) and reclassification (net reclassification index 11.38% [P < .0001], integrated discrimination improvement 5.24% [P = .02]). CONCLUSIONS: The BUN/Cr ratio is associated with worsening kidney function and adds incremental risk prediction information relative to traditional predictive measures in outpatients with heart failure at risk for worsening kidney disease.

The double helix angiography of right coronary arteries: false lumen stenting of a type F right coronary artery spiral dissection with late recanalization of the true lumen and occlusion of the stented false lumen.

Guide catheter induced dissection of coronary arteries is an uncommon, but serious complication of coronary angioplasty. Treatment can include emergent coronary artery bypass grafting to the affected vessel or percutaneous intervention including wiring the true lumen and exclusion stenting of the dissection flap to prevent further propagation. Detailed descriptions have been published of techniques of intentional passage of guide wires into the false lumen and reentry into the true lumen with chronic total occlusions. We present an unusual case of what appeared to be successful intentional false lumen stenting with reentry into the true lumen of an iatrogenic dissection of the right coronary artery with restoration of TIMI III coronary flow which, one year later, was complicated by recanalization of the true lumen and occlusion of the stented false lumen causing symptomatic angina.

Eosinophilic myocarditis: two case reports and review of the literature.

BACKGROUND: Eosinophilic myocarditis is a rare and often under-diagnosed subtype of myocarditis with only around 30 cases published in the medical literature. In this article we present two patients with eosinophilic myocarditis with the aim to demonstrate the often elusive nature of the disease and present the current scientific literature on this topic. CASE PRESENTATION: A 76 years old Caucasian gentleman and a 36 years old Aboriginal gentleman both presenting with heart failure symptoms were eventually diagnosed with eosinophilic myocarditis after extensive evaluation. Their presentation, assessment, and medical management is explored in this article. CONCLUSIONS: Eosinophilic myocarditis remains a rare and likely under-diagnosed subtype of myocarditis. The key features of this disease include myocardial injury in the setting of non-contributory coronary artery disease. Endomyocardial biopsy remains the definitive gold standard for diagnosis of noninfectious eosinophilic myocarditis. Non-invasive cardiac imaging in the setting of peripheral eosinophilia can be strongly suggestive of eosinophilic myocarditis with potential for earlier diagnosis. Failure to diagnose eosinophilic myocarditis and the delay of therapy may lead to irreversible myocardial injury. Therapies for this disease have yet to be validated in large prospective studies.

Reduced hospitalizations in severe, refractory congestive heart failure with peritoneal dialysis: a consecutive case series.

BACKGROUND: Peritoneal dialysis (PD) for long-term management of diuretic resistant volume overload in heart failure (HF) may provide potential benefit with few adverse consequences. We examined the impact of PD on clinical status hospitalizations, and complications of therapy in severe end-stage HF. METHODS: A consecutive case series of 10 transplant ineligible patients receiving PD solely for HF volume management between 2007 and 2011 was evaluated with clinical data reviewed pre- and post-PD initiation. RESULTS: The mean ejection fraction (EF) pre-PD was 24.5 ± 6.0% with the majority of patients having NYHA class IIIB symptoms and moderate-severe right ventricular dysfunction. 9/10 patients were Stage 3 chronic kidney disease (CKD) or worse. After PD initiation, average weight loss was almost 7 kg (p = 0.016) with improvement in diuretic response, peripheral edema, and functional class. There was a significant decrease in re-hospitalization from an average of 3.2 ± 2.5 to 0.1 ± 0.3 admissions per patient (p = 0.007) and reduced average length of stay from 37 ± 36.7 to 0.78 ± 2.3 days (p = 0.019). SUMMARY: Objective criteriabased institution of PD for the treatment of diuretic refractory severe-end-stage HF was well tolerated and demonstrated favorable outcomes; these included improved clinical status, reduced hospitalizations and length of stay, with very few and easily treatable PDrelated complications. PD appears to be a viable option in refractory, end-stage congestive heart failure (CHF).
