2 Key issues in Chronic Heart Failure Chronic Heart Failure (CHF) is Common 2% of the population Dangerous high mortality Disabling high morbidity Costly 2% of health care budget Treatable very successful pharmacological therapy developed ESC Guidelines for the Diagnosis and Treatment of CHF

3 ESC Guidelines for the Diagnosis and Treatment of CHF

4 Classes of recommendations I II IIa IIb III Condition for which there is evidence and/or general agreement that a given procedure or treatment is useful and effective Condition for which there is conflicting evidence and /or a divergence of opinion about the usefulness / efficacy of a procedure or treatment Weight of evidence /opinion is in favour of usefulness / efficacy Usefulness/efficacy is less well established by evidence / opinion Evidence or general agreement that the treatment is not useful/effective and in some cases may be harmful Levels of Evidence A B C Data derived from multiple randomized clinical trials or meta-analyses Data derived from a single randomized trial or large non randomized studies Consensus of opinion of experts and/or small studies, retrospective studies, registries ESC Guidelines for the Diagnosis and Treatment of CHF

5 Relationship between cardiac dysfunction, HF and HF rendered asymptomatic NORMAL CARDIAC DYSFUNCTION CORRECTED OR RESOLVED Therapy CAN be withdrawn without recurrence of symptoms Transient Heart Failure CARDIAC DYSFUNCTION No symptoms Asymptomatic cardiac dysfunction SYMPTOMS Symptoms relieved Therapy CANNOT be withdrawn without recurrence of symptoms HEART FAILURE Symptoms persist Systolic dysfunction THERAPY ESC Guidelines for the Diagnosis and Treatment of CHF

6 Algorithm for Diagnosis of Chronic HF or LV Dysfunction ESC Guidelines for the Diagnosis and Treatment of CHF

7 NT-proBNP and BNP: Synthesis and secretion Stretched cardiac myocyte pre-probnp (134 amino acids) probnp (108 amino acids) signal peptide (26 amino acids) NT-proBNP (1-76) BNP 32 (physiologically active form) blood ESC Guidelines for the Diagnosis and Treatment of CHF

8 Natriuretic Peptides Plasma concentrations of certain natriuretic peptides or their precursors, especially BNP and NTproBNP, are helpful in the diagnosis of heart failure. A low-normal concentration in an untreated patient makes heart failure unlikely as the cause of symptoms. BNP and NT-proBNP have considerable prognostic potential, although evaluation of their role in treatment monitoring remains to be determined. ESC Guidelines for the Diagnosis and Treatment of CHF

9 Echocardiography and Doppler Echocardiography: preferred method for the documentation of cardiac dysfunction at rest. Left ventricular ejection fraction most important assessment to differentiate CHF patients with or without preserved systolic function. Diastolic dysfunction: evidence of abnormal left ventricular relaxation, diastolic distensibility or diastolic stiffness. ESC Guidelines for the Diagnosis and Treatment of CHF

10 Diastolic dysfunction or Preserved Left Ventricular Ejection Fraction (PLVEF) Diastolic heart failure is often presumed to be present when symptoms and signs of heart failure occur in the presence of a PLVEF (normal ejection fraction/normal end-diastolic volume) at rest. Predominant diastolic dysfunction is relatively uncommon in younger patients but increases in importance in the elderly, in particular women, in whom systolic hypertension and myocardial hypertrophy with fibrosis are contributors to cardiac dysfunction.

33 ARBs and CHF Update 2005 In patients with systolic dysfunction ARBs are a good alternative to ACE-inhibition in symptomatic patients intolerant to ACE-inhibitors to improve morbidity and mortality (level of evidence B, class I) ARBs and ACE-inhibitors have similar efficacy in CHF (level of evidence B, class I) After acute myocardial infarction with signs of heart failure or left ventricular dysfunction, ARBs have similar efficacy to ACE-inhibitors (level of evidence B, class I) ESC Guidelines for the Diagnosis and Treatment of CHF

34 ARBs and CHF Update 2005 ARBs can be considered in combination with ACE-inhibitors in patients who remain symptomatic, to reduce mortality (level of evidence B, class IIa) and hospital admissions for heart failure (level of evidence A, class I) ESC Guidelines for the Diagnosis and Treatment of CHF

37 Update 2005 and AA Aldosterone receptor antagonist: is recommended in addition to ACE-inhibition, betablockers and diuretics in advanced heart failure (NYHA III-IV) to improve survival and morbidity (level of evidence B, class I) is recommended in addition to ACE-inhibition and beta-blockade in heart failure after myocardial infarction with left ventricular systolic dysfunction and signs of heart failure to reduce mortality and morbidity (level of evidence B, class I) ESC Guidelines for the Diagnosis and Treatment of CHF

38 Update 2005 and AA Whether an aldosterone antagonist is of proven benefit in patients with class II heart failure or asymptomatic left ventricular dysfunction remains to be established When symptoms increase, which neurohormonal antagonist to add is difficult to determine ESC Guidelines for the Diagnosis and Treatment of CHF

39 Pharmacological therapy of heart failure due to Left Ventricular Systolic Dysfunction NYHA I For Survival/Morbidity mandatory therapy Cont. ACE-inhibitor/ARB if ACEinhibitor intolerant, continue aldosterone antagonist if post-mi add beta-blocker if post-mi For Symptoms reduce / stop diuretic NYHA II ACE-inhibitor as first-line treatment/arb if ACE-inhibitor intolerant add betablocker and aldosterone antagonist if post MI +/- diuretic depending on fluid retention NYHA III ACE-inhibitor plus ARB or ARB alone if ACE intolerant beta-blocker add aldosterone antagonist + diuretics + digitalis If still symptomatic NYHA IV Continue ACE-inhibitor/ARB beta-blocker Aldosterone antagonist +diuretics + digitalis + consider temporary inotropic support ESC Guidelines for the Diagnosis and Treatment of CHF

40 Treatment of patients with preserved ejection fraction (PSEF) ACE-inhibitors may improve relaxation and cardiac distensibility directly and may have long-term effects through their anti-hypertensive effects and regression of hypertrophy and fibrosis. Diuretics may be necessary when episodes with fluid overload are present, but should be used cautiously so as not to lower preload excessively. Beta-blockade could be instituted to lower heart rate and increase the diastolic period. Verapamil-type calcium antagonists may be used for the same. A high dose of an ARB may reduce hospitalizations. ESC Guidelines for the Diagnosis and Treatment of CHF

48 ICD Implantation of an ICD in combination with bi-ventricular pacing can be considered in patients who remain symptomatic with severe heart failure NYHA class III-IV with LVEF <35% and QRS duration > 120 msec to improve mortality or morbidity (level of evidence B, class IIa) ICD therapy is recommended to improve survival in patients after cardiac arrest or who have sustained ventricular tachycardia, with reduced systolic left ventricular function (level of evidence A, class I) ICD implantation is reasonable in selected symptomatic patients with left ventricular ejection fraction <30-35%, not within 40 days of a myocardial infarction, on optimal background therapy including ACE-inhibitor, ARB, betablocker and an aldosterone antagonist, where appropriate, to reduce sudden death (level of evidence A, class I) ESC Guidelines for the Diagnosis and Treatment of CHF

49 Conclusions Treatment of CHF with a combination of various neuroendocrine antagonists has resulted in substantial improvements in outcomes in this malignant syndrome over a relatively short period of time. Implementation of ESC Guidelines will provide optimal evidence based therapy. ESC Guidelines for the Diagnosis and Treatment of CHF
