Worsening (decompensated) HF – Preexisting and stable HF that worsens suddenly or progressively is described as decompensated AHF. New (de novo) HF - There is no known previous HF. Symptoms and findings appear suddenly after an acute event [e.g. acute myocardial infarction (AMI)] or gradually in the presence of asymptomatic left ventricular systolic and/or diastolic dysfunction. In-hospital worsening heart failure Frequency of in-hospital worsening heart failure: 4.5-30%. Mortality is ~19% in 30-day and 50% in 1-year compared to 7.3% and 32.7%, respectively, in those with an uncomplicated course. In-hospital worsening renal function Frequency of in-hospital worsening renal function: 20-30%, sign of increaed 90-day mortality. In-hospital events Worsening heart failure Worsening renal function Ischemic hepatitis Congestive hepatopathy Failure to improve or worsening signs and symptoms of HF despite therapy that occurs 1-2 days (usually in the first 7 days) after hospitalization and requires initiation or intensification of parenteral therapy [e.g. inotropes or vasoactive agents] or implementation of mechanical cardiac or ventilatory support. Increase in serum creatinine of ≥0.3 mg/dL or decrease in eGFR ≥25% after admission. Decreased blood supply (due to shock or low blood pressure) to liver resulting in liver injury and marked elevation of liver function tests Liver dysfunction due to venous congestion, usually right heart failure Contents Definitions Epidemiology Clinical Evaluation and Diagnostic Approach Management in ED/CCU/Ward Clinical Characteristic of Acute Heart Failure Patients in Different Registries AHF is reported as the cause of hospitalization in 20% of cases older than 65 years. About 30–50% of the AHF patients have preserved LVEF. I n-hospital mortality rate of AHF is similar to AMI and ranges between 4–7% in registry studies. Farmak,s D, et al.

Contents Definition Epidemiology Clinical Evaluation and Diagnostic Approach Management in ED/CCU/Ward Precipitating causes Cardiac Treatment noncompliance: 1. Salt and fluid intake 2. Non-compliance with drug treatment Ischemic Heart Disease: 1. Acute coronary syndrome 2. Mechanical complications of AMI 3. Right ventricular MI Valvular Heart Disease: 1. Valvular stenosis 2. Valvular regurgitation 3. Endocarditis 4. Aortic dissection Cardiomyopathies: 1. Peripartum CMP 2. Acute myocarditis 3. Pericardial tamponade Hypertensive/Arrhythmic: 1. Hypertension 2. Acute arrhythmias (e.g. AF, tachyarrhythmias, serious bradycardia, etc.) Concomittant usage of negative inotropic drugs: Verapamil, beta-blockers, diltiazem, nifedipine, etc. Non-Cardiac Endocrinological diseases: Diabetes, thyrotoxicosis, hypothyroidism, etc. Pulmonary diseases: Pulmonary emboli, asthma, COPD Infections: Pneumonia, influenza, sepsis, etc. Cases increasing blood volume: Anemia, shunts, beriberi, Paget disease Renal failure Drugs and addictions: Drugs leading to sodium retention (e.g. steroids, tiazolidinediones, NSAI's), excessive alcohol or illegal drug addiction Others: Cerebrovascular event, surgical intervention Symptoms and signs The main symptoms which dominates clinical presentation is related to the systemic and pulmonary congestion. 1. Pulmonary congestion: The accumulation of an abnormal amount of blood in the vascular bed of the lungs. It usually occurs in asso ciation with left heart failure. 2. Systemic congestion: Congestion of the subsidiary organs of the systemic circulation as a result of right heart failure. The main symptoms are edema, venous congestion in the lower extremities, liver and spleen, liver and splenic congestion, and engorgement jugular. Demographical and clinical characteristics of 5 clinical scenarios of AHF Diagnostic tests Chest X ray Enlarged heart silhouette, pulmonary congestion, pleural effusion, Kerley lines pulmonary interstitial or alveolar edema. A normal chest radiogram (observed in ~20% of cases) does not exclude AHF diagnosis. ECG ECG should be performed at initial evaluation in all AHF patients and cardiac rhythm should be monitored. ECG is almost always abnormal in patients admitted with acute decompensated HF. Diagnostic tests Hemogram Blood glucose Urea, creatinine, BUN and estimated eGFR Creatinine and electrolytes should be monitored at short intervals (daily during IV treatment, in 1-2 days after starting oral treatment) during AHF treatment. Electrolytes Transaminases Liver function abnormalities are detected in about 75% of AHF patients and are closely related to the severity of disease and clinical findings. C-reactive protein Myocardial injury biomarkers Increase in troponin is observed in 30-50% of cases (even without myocardial infarction) BNP or NT-proBNP - Initial evaluation of suspected AHF - Patients with ongoing symptoms in CCU/ward -Prior to discharge Diagnostic tests Echocardiography: Differential diagnosis Thoracic ultrasonography: Pulmonary and to plan treatment of AHF. congestion. B lines in congestion (comet tails) whereas A lines chronic obstructive If can be performed in ED, it provides pulmonary disease. information about etiology of AHF, cardiac anatomy (e.g. volumes, geometry, mass) and functions. A lines B-lines arise from the pleural line, creating a pattern called lung rockets. These vertical, long, well-defined artifacts erasing the A-lines and moving in concert with lung sliding indicate the changeover from below to above 18 mm Hg when this pattern replaces A-lines during fluid therapy. Contents Definition Epidemiology Clinical Evaluation and Diagnostic Approach Management in ED/CCU/Ward Management of AHF Main objectives of AHF treatment are symptomatic relief and hemodynamic recovery. Other initial treatment objectives are improving oxygenation to required levels (PaO2 >60 mm Hg, SpO2 >90%), restriction of organ damage and decreasing duration of stay in intensive care unit. Management in Emergency Department Venous line Monitorization ECG: Baseline and follow-up SaO2 monitorization (pulse oxymeter): If < 90% administer nasal oxygen (with cannula or mask; goal: >95%) Blood pressure (Invasive continuous [arterial line], noninvasive, 5 minute apart). Urine output Invasive hemodynamic monitorization Swan-Ganz (pulmonary artery) catheterization, which had been used more frequently in former years, is currently recommended only in selected cases, as it does not add more information to those obtained by non-invasive methods. Patients who would benefit from hemodynamic monitorization are: (i) patients with hypotension/cardiogenic shock who don't respond to fluid treatment, (ii) ACS patients with mechanical complications, (iii) cases not responsive to standard treatment, and measurement of intravascular volume, cardiac output and pulmonary capillary wedge pressure will be beneficial in planning the treatment, (iv) cases who are candidates for heart transplantation or implantation of a LVAD. Intra-arterial catheterization is used to monitor mean arterial pressure in patients with low SBP in whom signs of AHF don't improve morbidity or mortality. It is also beneficial for patients who receive vasopressor treatment and in whom arterial blood gas analysis should be repeated frequently. Management in Emergency Department Diuretic treatment: Furosemide 20-40 mg IV bolus Diuretic response (urine output >100 mL/h in first two hours, relief of dyspnea) should be waited after this initial dose. Vasoactive treatment : In patients with a SBP >110-120 mmHg, time between first admission and initiation of IV nitrates should not be more than 2 hours. Sublingual or oral nitrate treatment instead of parenteral forms of vasodilators can be preferred for patients with relatively less serious symptoms and findings in emergency unit. Management in Emergency Department Routine opioid administration: There is no strong evidence supporting benefits of routine use. Morphine at a dose of 4-8 mg can be applied with metoclopropamide (morphine induces nausea) in patients with significant anxiety, then again respiration should be monitored carefully. Triage into CCU/ICU Patients with a respiratory rate >25/min, SaO2 <90% or requiring intubation, Systolic BP <90 mm Hg, Hypoperfusion findings (existence of any: lactate >2 mmol/L, confusion, metabolic acidosis, oliguria, cold extremities in room temperature, mixed venous oxygen saturation <65%) should be directed into CCU/ICU. Patients without critical findings can be followed in ward and receive treatment including parenteral drugs. Triage: Discharge to home Approximately half of AHF patients can be discharged from emergency department. Patients subjectively mentioning she/he has recovered, Resting heart rate <100/min, Room air oxygen saturation ≥95%, Urine output >30 cc/h, No orthostatic hypotension or end organ dysfunction are potential candidates for early discharge. These rules are not valid for de novo AHF patients who should always be hospitalized. Management in ICU/CCU Fluid and sodium restriction – Although a strict fluid restriction is not recommended, a fluid intake of 1.5-2 L/day is commonly recommended for AHF patients (especially for hyponatremic cases) to relieve symptoms and congestion during the initial management. Sodium restriction (to 2‒3 g/day) may also help to control the symptoms and signs of congestion. Nonetheless, there is no clear evidence to support these recommendations. Venous thromboembolism prophylaxis – Hospitalization due to AHF carries a high risk for development of venous thromboembolism. Therefore prophylactic anticoagulation (enoxaparin 40 mg subcutaneously once daily or unfractionated heparin 5000 units 3 times/day subcutaneously) is recommended for patients during the hospital stay. However, evidence from randomized clinical trials are lacking for this recommendation. Ventilation Indications for noninvasive ventilation 1. 2. 3. 4. 5. 6. Inadequate response to initial standard therapy High-risk of endotracheal intubation Respiratory rate ≥30/min Persistent O2 saturation ≤ 90% or PaO2/FiO2 <200 mmHg on >4 L/min oxygen Mild hypercapnia (CO2 <45 mmHg) or acidosis (pH <7.3) Respiratory muscle fatigue FiO2 = fraction of inspired oxygen, PaO2 = partial pressure arterial oxygen. A-CPAP settings: • Start with 5- H2O • Increase in increments of H2O, as tolerated and indicated • FiO2 >40% B-BIPAP settings: • Initial inspiratory pressure of 8–10 cm H2O • Increase in increments of 2–4 cm H2O (Max ~20 cm H2O) aiming at tidal volume >7ml/kg • Initial expiratory pressure of ~4- H2O • Maximum inspiratory pressure is H2O and expiratory pressure H2O • FiO2 >40% Ventilation Indications for endotracheal ventilation Any 1 of the following: • pH less than 7.20 • pH 7.20–7.25 on 2 occasions 1 hour apart • Hypercapnic coma (Glasgow Coma Scale score < 8 and PaCO2 >60 mm Hg) • PaO2 less than 45 mm Hg • Cardiopulmonary arrest Two or more of the following in the context of respiratory distress: • Respiratory rate >35 breaths/min or <6 breaths/minute • Tidal volume <5 mL/kg • Blood pressure changes, SBP <90 mm Hg • SaO2 <90% despite adequate supplemental oxygen • Hypercapnia (PaCO2 >10 mm increase) or acidosis (pH decline >0.08) from baseline • Obtundation • Diaphoresis • Abdominal paradox Treatment approach according to systolic blood pressure Diuretics IV bolus administration of loop diuretics (approximately 2.5 times the outpatient dose should be considered) may be followed by continuous IV infusion. Urine output should be increased to ≥40 mL/h and a weight loss of 1-1.5 kg/day should be achieved. Patient’s BP, fluid balance, weight at the same hour of each day (preferably in the morning), daily renal functions and electrolytes should be monitored as long as parenteral treatment continues.
