Clinical Heart fAilure Management Program: Changing the practice by partnering primary care and specialists (CHAMP-HF).

Background: While significant gains were made in the management of heart failure (HF), most patients are still diagnosed when they are acutely ill in hospital, often with advanced disease. Earlier diagnosis in the community could lead to improved outcomes. Whether a partnership and an educational program for primary care providers (PCP) increase HF awareness and management is unknown.

Optimization of pharmacotherapies for ambulatory patients with heart failure and reduced ejection fraction is associated with improved outcomes.

Background: In heart failure, specific target doses for each drug are recommended, but some patients receive suboptimal dosing, others are undertreated or remain chronically in a titration phase, despite having no apparent contraindication or intolerance. We assessed the association of different levels of adherence to guidelines with outcomes in patients with heart failure and reduced ejection fraction (HFrEF).

Methods: Medical records of patients with HFrEF followed at our heart failure (HF) clinic for at least 6 months (n = 511) were reviewed and patients categorized as: 1) optimized (25.

Early Detection and Correction of Cerebral Desaturation With Noninvasive Oxy-Hemoglobin, Deoxy-Hemoglobin, and Total Hemoglobin in Cardiac Surgery: A Case Series.

Regional cerebral oxygen saturation (rS o2 ) obtained from near-infrared spectroscopy (NIRS) provides valuable information during cardiac surgery. The rS o2 is calculated from the proportion of oxygenated to total hemoglobin in the cerebral vasculature. Root O3 cerebral oximetry (Masimo) allows for individual identification of changes in total (ΔcHbi), oxygenated (Δ o2 Hbi), and deoxygenated (ΔHHbi) hemoglobin spectral absorptions.

Care Gaps in Adherence to Heart Failure Guidelines: Clinical Inertia or Physiological Limitations?

Objectives: This study evaluated the impact of clinical and physiological factors limiting treatment optimization toward recommended medical therapy in heart failure (HF).

Background: Although guidelines aim to assist physicians in prescribing evidence-based therapies and to improve outcomes of patients with HF and reduced ejection fraction (HFrEF), gaps in clinical care persist.

Methods: Medical records of all patients with HFrEF followed for at least 6 months at the authors' HF clinic (n = 511) allowed for drug optimization and were reviewed regarding the prescription rates of recommended pharmacological agents and devices (implantable cardioverter-defibrillator [ICD] or cardiac resynchronization therapy [CRT]).

A comparison of the effects of selective and non-selective mineralocorticoid antagonism on glucose homeostasis of heart failure patients with glucose intolerance or type II diabetes: A randomized controlled double-blind trial.

Mineralocorticoid receptor antagonists (MRAs) decrease morbidity and mortality in patients with heart failure (HF). However, spironolactone, a non-selective MRA, has been shown to exert a harmful effect on glucose homeostasis. The objective of this multicenter, randomized, controlled, double-blind trial was to compare the effects of spironolactone to those of the selective MRA eplerenone on glucose homeostasis among 62 HF patients with glucose intolerance or type II diabetes.

The Association Between Pulsatile Portal Flow and Acute Kidney Injury after Cardiac Surgery: A Retrospective Cohort Study.

Objective: Venous congestion is a possible mechanism leading to acute kidney injury (AKI) following cardiac surgery. Portal vein flow pulsatility is an echographic marker of cardiogenic portal hypertension and might identify clinically significant organ congestion. This exploratory study aims to assess if the presence of portal flow pulsatility measured by transthoracic echography in the postsurgical intensive care unit is associated with AKI after cardiac surgery.

Changes in Outcomes of Cardiac Allograft Vasculopathy Over 30 Years Following Heart Transplantation.

Objectives: This study investigated temporal changes in the demographics and the prognosis of cardiac allograft vasculopathy (CAV) over 30 years following heart transplantation (HTx).

Background: Effects of the changing HTx demographics on CAV outcomes, based on International Society for Heart and Lung Transplantation (ISHLT) classification of CAV, have been incompletely investigated.

Methods: Patients who underwent HTx at the Montreal Heart Institute were classified according to the severity of CAV (CAV 0 is no presence of CAV; CAV 1 is mild, CAV 2 to 3 is moderate to severe) and era of HTx (early: 1983 to 1998; recent: 1999 to 2011).

Noncardiovascular Disease and Critical Care Delivery in a Contemporary Cardiac and Medical Intensive Care Unit.

Background: Noncardiovascular comorbidities and critical illness are increasing in cardiovascular intensive care units (CICUs). There are limited data comparing critical care delivery, resource utilization, and costs between contemporary CICUs and medical intensive care units (MICUs).

Methods: All CICU (n = 6967; 22 748 patient-days) and MICU (n = 10 892; 39 211 patient-days) admissions to Cedars-Sinai Medical Center, a tertiary care academic medical center, between January 2011 and December 2016 were reviewed.

Canadian Cardiovascular Society/Canadian Cardiovascular Critical Care Society/Canadian Association of Interventional Cardiology Position Statement on the Optimal Care of the Postarrest Patient.

Out of hospital cardiac arrest (OHCA) is associated with a low rate of survival to hospital discharge and high rates of neurological morbidity among survivors. Programmatic efforts to institute and integrate OHCA best care practices from the bystander response through to the in-hospital phase have been associated with improved patient outcomes. This Canadian Cardiovascular Society position statement was developed to provide comprehensive yet practical recommendations to guide the in-hospital care of OHCA patients.

Extracardiac Signs of Fluid Overload in the Critically Ill Cardiac Patient: A Focused Evaluation Using Bedside Ultrasound.

Fluid balance management is of great importance in the critically ill cardiac patient. Although intravenous fluids are a cornerstone therapy in the management of unstable patients, excessive administration coupled with cardiac dysfunction leads to elevation in central venous pressure and end-organ venous congestion. Fluid overload is known to have a detrimental effect on organ function and is responsible for significant morbidity in critically ill patients.

Preoperative Optimization of the Heart Failure Patient Undergoing Cardiac Surgery.

Heart failure patients who undergo cardiac surgery are exposed to significant perioperative complications and high mortality. We herein review the literature concerning preoperative optimization of these patients. Salient findings are that end-organ dysfunction and medication should be optimized before surgery.

From Coronary Care Units to Cardiac Intensive Care Units: Recommendations for Organizational, Staffing, and Educational Transformation.

Medical care in Canadian cardiac units has changed considerably over the past 3 decades in response to an increasingly complex and diverse patient population admitted with acute cardiac pathology. To maintain the highest level of care for these patients, there is a pressing need to evolve traditional coronary care units into contemporary cardiac intensive care units. In this article we aim to highlight the current variations in Canadian units, develop approaches to overcome logistical and infrastructural obstacles, and propose staffing and training recommendations that would allow for the establishment of contemporary cardiac intensive care units.

Decreased circulating and neutrophil mediated VEGF-A165 release in stable long-term cardiac transplant recipients.

Background: Vascular endothelial growth factor (VEGF) may play a role on the allograft remodelling following cardiac transplantation (CTx). We measured the circulating levels of VEGF-A165 concomitantly with the proinflammatory (Interleukin-8; IL-8), anti-inflammatory (IL-1 receptor antagonist; IL-1RA) and their release from neutrophils of CTx recipients.

Methods: Eighteen CTx recipients aged 49.

Innovative approaches in the perioperative care of the cardiac surgical patient in the operating room and intensive care unit.

Perioperative care for cardiac surgery is undergoing rapid evolution. Many of the changes involve the application of novel technologies to tackle common challenges in optimizing perioperative management. Herein, we illustrate recent advances in perioperative management by focusing on a number of novel components that we judge to be particularly important.

Heart failure with anemia: novel findings on the roles of renal disease, interleukins, and specific left ventricular remodeling processes.

Background: Anemia is a highly prevalent and strong independent prognostic marker in heart failure (HF), yet this association is not completely understood. Whether anemia is simply a marker of disease severity and concomitant chronic kidney disease or represents the activation of other detrimental pathways remains uncertain. We sought to determine which pathophysiological pathways are exacerbated in patients with HF, reduced ejection fraction (HFrEF) and anemia in comparison with those without anemia.

Long-term evolution, secular trends, and risk factors of renal dysfunction following cardiac transplantation.

Recent reports suggest that individuals who underwent heart transplantation in the last decade have improved post-transplant kidney function. The objectives of this retrospective study were to describe the incidence and to identify fixed and time-dependent predictors of renal dysfunction in cardiac recipients transplanted over a 25-year period (1983-2008). To illustrate temporal trends, patients (n = 306) were divided into five groups based on year of transplantation.

An unusual case of giant cell myocarditis missed in a Heartmate-2 left ventricle apical-wedge section: a case report and review of the literature.

Herein we present a case of fulminant myocarditis in a woman previously treated for B-cell lymphoma. While the clinical context was suggestive of adriamycin-induced cardiomyopathy, the initial pathology of the Heartmate-2 apical core showed lymphocytic myocarditis. After 8 months of stability, the patient presented with progressive heart failure and recurrent ventricular arrhythmias.

Impaired heart rate responses and exercise capacity in heart failure patients with paced baseline rhythms.

Background: Conduction system disease and beta-blocker therapy are both common among heart failure (HF) patients and contribute to increasing reliance on paced rhythms. We hypothesized that many HF patients dependent on pacing have suboptimal heart rate responses and associated limitations in exercise capacity.

Methods And Results: We studied 122 HF patients (left ventricular ejection fractions ≤40%) referred for cardiopulmonary exercise testing, comparing those with pacing at baseline with those with native rhythms.

Rubbing salt into wounds: hypertonic saline to assist with volume removal in heart failure.

Traditionally accepted management strategies for patients with heart failure include sodium and fluid restriction, neurohormonal blockade, and the use of loop diuretics to achieve and maintain euvolemia. Despite continued advances in medical and device therapy, fluid management remains a significant problem in patients with the cardiorenal syndrome (manifested as diuretic resistance and worsening renal function with more aggressive attempts at volume removal). This article examines the counterintuitive use of hypertonic saline as a potential therapy to facilitate diuresis in patients with decompensated heart failure and diuretic resistance.
