Changing Paradigms Traditional FocusTransformational Focus Immediate clinical needsComprehensive needs of the whole person Patients as recipients of carePatients and families as essential, active members of the care team Varity of different teams based on setting of care Cross continuum teams with a focus on the patient plan over time Key Areas: 1.Patient education with Teach Back 2.Multidisciplinary rounds (bedside is best) 3.Post discharge follow up-medical homes 4.Early follow up-timely appointments 5.Medication reconciliation 6.Proactive thinking-treat symptoms early Slide 9 Cross-Continuum Team Collaboration Key Elements Health Information Exchange & Shared Care Plans Patient and Family Engagement Identify those at riskCase reviews Nursing competencies Medication reconciliationS-BAR for status change reports Nursing home capabilitiesAccess to the EMR Telehealth Shared CHF patient education materials Advance care planningMedical homes Slide 10 I NTERACT Communicatio n Tools Decision Support Tools Advance Care Planning Tools Quality Improveme nt Tools Go tohttp://www.interact2.net/tools.html Slide 11 Signs of Transition to End-Stage HF End-of-life care should be considered in patients who have symptoms at rest despite repeated attempts to optimize pharmacologic, cardiac device, and other therapies, as evidenced by 1 or more of the following: Multiple hospital admissions. Chronic poor quality of life with minimal or no ability to accomplish activities of daily living. Multiple implantable defibrillator shocks. Inability to control the heart failure with standard medications. Need for continuous intravenous inotropic therapy support to increase myocardial contractility. Heart Failure Society of America Heart Failure is a Chronic, Progressive Illness Patients with heart failure report high symptom burden, including Pain Anxiety Shortness of breath Mortality rates can be as high as 30% once the patient presents to the ER multiple times. Slide 12 So how are we doing? Slide 13 What does the future hold? Trained facilitators across the community for Advance Care Planning Increased use of technology used to complete assessments SNFistsphysicians and/or Advance Practice Nurses whose whole practice focuses on SNF patients Shared competency training sessions with use of simulation and other approaches. Slide 14 Slide 15 Clinical syndrome of: Decreased exercise tolerance Fluid retention Due to structural heart disease Slide 16 Cardiac output = the amount of blood the heart is able to pump in 1 minute (Normal range approximately 5 liters) Stroke volume = the amount of blood the heart pumps with each contraction Peripheral vascular resistance (PVR) = resistance encountered in all vessels Affected by: Radius of arteries Blood viscosity Blood volume Aortic valve Pulmonic valve Slide 17 Cardiac Output = Stroke Volume x Heart Rate Mean Arterial Blood Pressure = Cardiac Output x Peripheral Vascular Resistance (PVR) Slide 18 Systole Diastole Slide 19 Alteration in pressures of the vascular system Hemodynamics Perception of decreased blood volume Neurohumoral mechanisms Slide 20 Not just for the ICU nurse anymore! Slide 21 Forces that affect circulating blood throughout the body and in and out of chambers of the heart Relationship between: Preload (volume, stretch) Afterload (resistance) Blood pressure measurement and palpating a pulse reflect degree of stability Basically getting the blood where it needs to go! Slide 22 Force that stretches muscle fibers of a resting heart how much they are stretched just prior to contraction What determines stretch ? 1. The amount of blood present in R & L atria 2. Condition of the myocardium The greater the volume of blood in the heart the greater the preload Blood volume muscle stretches stroke volume .up to a point! Slide 23 Relationship between fiber stretch and contractile force The more it is stretched in diastole (filling or resting) the harder it contracts in systole If stretches too much, output decreases Slide 24 Tension that ventricle must generate to overcome resistance to ejection To open aortic valve and eject blood, left heart needs to overcome resistance of: Peripheral vascular resistance (PVR) (HTN) Aortic Valve (Aortic stenosis) Right heart must overcome resistance of: Pulmonary vascular system (Hypoxemia) Slide 25 Affected by: Preload Stretch Volume Afterload Resistance Cove r-up this Slide 26 Slide 27 Hypotension (doesnt occur initially) Tachycardia Cool, clammy skin Decreased urine output Alteration in mental status Slide 28 Heart (pump) failure cardiogenic shock Increased preload, increased stretch Compensatory initially but if pressure increases too much stretch goes too far and stroke volume decreases CO = SV x HR Overstretched LV contractility SV cardiac output perception of decreased blood volume Slide 29 Occurs secondary to perception of decreased blood volume Norepinephrine - vasoconstriction, increased contractility Epinephrine increased heart rate and increased contractility Stimulates secretion of renin activation of renin angiotensin aldosterone system Slide 30 Renin excreted by kidney in response to 1.decrease in BP 2.sympathetic stimulation 3.decreased serum sodium (Na+) 4.decreased renal blood flow Slide 31 Slide 32 Norepinephrine Vasoconstriction BP (afterload), stimulates production of renin Angiotensin II BP (afterload) Aldosterone (saves water and sodium, wastes potassium) preload and afterload afterload SVR (resistance the heart has to pump against) preload stretch of ventricles (stretch too much) WHOOPS Cardiac Output even more Slide 33 Increases the blood pressure and heart rate Increases the resistance that the heart has to pump against Increases the work of the heart Increases the volume that the heart has to pump through the system Slide 34 Slide 35 Cardiac Increased workload leads to increased O2 consumption and angina Decreased contractility leads to low output Tachycardia, dysrhythmias Low output leads to low BP and decreased tissue perfusion, lowered exercise tolerance Jugular vein distention, increased CVP, systemic edema Slide 36 Right Heart FailureLeft Heart Failure Causes Left HF, COPD (cor pulmonale), PE, RV infarction, pulmonary HTN Pathophysiology Output of RV < venous return venous congestion and decreased output to lungs Causes MI, HTN, AR, AS, cardiomyopathy Pathophysiology Decreased cardiac output Slide 37 Slide 38 Decreased cardiac output from left ventricle Increased preload left heart Increased pressure in pulmonary vascular system Fluid moves from pulmonary capillaries into lung tissue impaired diffusion of oxygen and carbon dioxide Slide 39 Dyspnea Ask many questions Any activities youve stopped doing? Any modifications by caregiver? Cough Orthopnea Paroxysmal Nocturnal Dyspnea Dyspnea on exertion (DOE) Slide 40 ClassPatient Symptoms Class I (Mild)No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, or dyspnea Class II (Mild)Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity results in fatigue, palpitation or dyspnea Class III (Moderate)Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity causes fatigue, palpitation, or dyspnea Class IV (Severe)Unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency at rest. If any physical activity is undertaken, discomfort is increased.

Increased BP Nonadherence? SNS activity? Heart rate Stroke volume x heart rate = Cardiac output Too low cardiac output drops Too high, ventricular filling time decreases stroke volume Respiratory rate Slide 62 Dyspnea Crackles Peripheral Edema Slide 63 Signs of hypervolemia may be absent in patients with worsening heart failure Miller, Frana, Rodriquez, Laule-Kilian, Perruchoud (2005) Increased filling and intravascular pressures may be present before clinical manifestations Stevenson, Perloff (1989) Volume overload frequently present in nonedematous patients Androne, Hryniewicz, Hudaihed, Mancini, Lamanca, Katz (2004) Slide 64 Need multiple assessment approaches Slide 65 Angiotensin Converting Enzyme Inhibitors Angiotensin Receptor Blockers Beta Blockers Diuretics Others. Slide 66 Inhibit ACE prevents angiotensin I from converting to angiotensin II Angiotensin II is a potent vasoconstrictor (Blocked = total peripheral resistance) Angiotensin II blocks release of nitric oxide (Blocked = total peripheral resistance) Angiotensin II stimulates aldosterone production sodium and water retention and potassium elimination (Blocked = ECF, hyperkalemia) Slide 67 Decreases total peripheral resistance and extracellular fluid volume, also glomerular filtration pressure (renal protective) Decreases preload and afterload Side effects first dose hypotension, (especially if on diuretics), hyperkalemia, cough, rash, angioedema Captopril (Capoten), benazepril (Lotensin), enalapril (Vasotec), quinnapril (Accupril), lisinopril (Prinivil), quinapril (Accupril), others Slide 68 Block angiotensin II receptors Decreased preload and afterload Similar effects No cough, less hyperkalemia Angiotensin II also produced by pathways that dont involve ACE i.e. lungs- ARBs can completely block ALL activity. Candesartan (Atacand), losartan (Cozaar), valsartan (Diovan) others Slide 69 SNS activation effects of norepinephrine and epinephrine increase heart rate, vasoconstriction, contractility and renin release Block that response Non selective Propanolol (Inderal) Carvedilol (Coreg) (also alpha 1 blocker) Labetalol (Normodyne, Trandate) also alpha 1 Selective Metoprolol (Lopressor, Toprol) Sustained release metoprolol (Toprol XL) Atenolol (Tenormin) Bisoprolol (Zebeta) *Approved for use in heart failure Heart failure, asthmatics, and diabetics Slide 70 5 classes Loop diuretics Thiazides Osmotics Potassium sparing Carbonic anhydrase inhibitor (weak) Block reabsorption of sodium and water urine output extracellular fluid volume Decreased preload Amount of solute as filtrate flows through nephron The earlier the site of action the greater the diuresis (more solute to work with so they make more of an impact) Slide 71 Loop diuretics Thiazides Potassium sparing Slide 72 Loop diuretics Most effective even when renal blood flow and creatinine clearance Block reabsorption of sodium and chloride in loop of Henle Furosemide (Lasix), bumetanide (Bumex), torsemide (Demadex) Also increases urinary excretion of potassium, magnesium, calcium If not responding to high dose Lasix (400 mg) GI absorption may be impaired due to congestion, torsemide better absorbed.

Consider support system Plans for follow up Parameters for weights, blood pressures, pulse Fluid restriction? Diet Information about medications Consider medication taking behaviors Daily routine Missed medication Assess understanding Slide 83 Patients with any 3 (orthopnea, edema, weight gain, need for diuretic dose and JVD) 4-6 weeks post discharge 2 year mortality x 3 Lucas, Johnson, Hamilton, et al. (2000) Number of clinical exacerbations (two or more of edema, dyspnea, orthopnea, PND, JVD, weight) Poor quality of life, decreased function and exercise tolerance, increased mortality 2 years Sayers, Riegel, Goldberg, Coyne, Samaha (2008) Slide 84 Multiple hospitalizations for exacerbations risk for mortality Medications limited by side effects (*renal function) Consider quality of life Education of client and support system Plan in place Slide 85 Heart failure is a syndrome that presents with alterations in hemodynamics and maladaptive responses of the sympathetic nervous system Signs and symptoms include those of diminished cardiac output and tissue congestion Multiple approaches to assessment are necessary to accurately identify acute decompensation The medication regimens for heart failure patients are effective but adherence is crucial Teaching plans should be holistic, consider each clients specific situation Heart failure exacerbations associated with decreased quality of life, increased mortality therefore addressing palliative and end of life care needs to be addressed following multiple hospitalizations
