1 hartfalen Mortaliteit door chronisch hartfalen > 70% op 8 jaar. Harttransplant is de enige mogelijke genezing, maar < 5% van deze patiënten komen daarvoor in aanmerking.Palliatieve zorgen wordt bij end-stage hartfalen erg belangrijk.Symptomen/klachten van deze patiënten in eindfase (laatste weken): angst, pijn, dyspnoe, oedemen, vermoeidheid, depressie, anorexie, incontinentie, constipatieFarmacotherapie van palliatieve zorgen in deze fase omvat O2, anxiolytica, morfine of andere narcotica, en antidepressiva, diuretica, digoxin, ACE inhibitoren, ARBs, en ß-blockers.
2 Small doses of morphine sulfate, such as 2-3 mg taken orally, may relieve dyspnea and pain. Doses may be titrated upwards as needed.
3 Summary the importance of Drug Therapy Recommendations for Chronic HF from the 2005 ACC/AHA GuidelinesSummarythe importance ofrisk factor modificationearly detectiontherapies proven to prevent and/or reduce morbidity and mortality.HF cannot be cured with drug therapy lifelong follow-up and patient education are needed to promote adherence to diet and medications.

9 β blockers in heart failure Potential mechanisms and benefits of β blockers:improved left ventricular function;reduced sympathetic tone; improved autonomic nervous system balance;up regulation of β adrenergic receptors;reduction in arrhythmias, ischaemia, further infarction, myocardial fibrosis, and apoptosis
10 Antithrombotic treatment In patients with chronic heart failure the incidence of stroke and thromboembolism is significantly higher in the presence of atrial and left ventricular dilatation, particularly in severe left ventricular dysfunction. Nevertheless, there is conflicting evidence of benefit from routine treatment of patients with heart failure who are in sinus rhythm with antithrombotic treatment, although anticoagulation should be considered in the presence of mobile ventricular thrombus, atrial fibrillation, and severe cardiac impairment. Large scale, prospective RCT of antithrombotic treatment in heart failure are in progress, such as the WATCH study (a trial of warfarin and antiplatelet therapy); the full results are awaited with interest.The combination of atrial fibrillation and heart failure (or evidence of left ventricular systolic dysfunction on echocardiography) is associated with a particularly high risk of thromboembolism, which is reduced by long term treatment with warfarin.
11 Chronic heart failure and atrial fibrillation Restoration and long term maintenance of sinus rhythm is less successful in the presence of severe structural heart disease, particularly when the atrial fibrillation is longstanding. In patients with a deterioration in symptoms that is associated with recent onset atrial fibrillation, treatment with amiodarone increases the long term success rate of cardioversion. Digoxin is otherwise appropriate for controlling ventricular rate in most patients with heart failure and chronic atrial fibrillation, with the addition of amiodarone in resistant cases.
12 diureticaThe guidelines note that periodic weight and symptom assessment should direct diuretic dosage adjustment, based on the patient's fluid status.In a nurse-driven telephone follow-up program, recently discharged HF patients were contacted at least weekly. Nurses assessed patients for symptoms of HF exacerbation and adjusted diuretic doses as appropriate. After one year, this intervention resulted in a 30% reduction in emergency department visits (p = 0.029) and readmissions (p = 0.045). In another study, a patient-driven sliding-scale diuretic protocol in patients with NYHA Class II-IV HF resulted in a 90% reduction in emergency department visits (p = 0.015). Diuretic dose adjustment was based on a 6 point questionnaire that evaluated signs (daily weights) and symptoms (dyspnea, peripheral edema) of HF. These data suggest that a flexible dosing strategy could enhance diuretic effectiveness.The relationship between diuretic use and the efficacy and safety of other HF therapies is also important. Symptoms of volume overload can arise upon initiation or dose escalation of a ß-blocker. Some ß-blocker clinical trials managed this complication by increasing the diuretic dose to regain a euvolemic state and improve tolerance of the increased ß-blocker dose.[40,43] Diuretic-induced volume depletion can negatively impact titration of both ACE inhibitors and ß-blockers by increasing the risk of hypotension. In the absence of fluid overload, diuretic dosage reduction should be considered.
13 Cox-inhibitoren en HFCyclooxygenase (COX) inhibitors (both COX-2 selective and nonselective) can cause fluid retention and congestive symptoms, which may attenuate diuretic efficacy.Thus, these agents should be used cautiously or avoided entirely in HF patients. The renal effects of COX inhibitors, along with diuretic-associated volume depletion, may result in additive risks of renal dysfunction.
